(NaturalNews) They help cut energy costs and make the nighttime street lighting around town a bit less orange and abrasive. But cutting-edge LED illumination is already on its way out in many cities following a warning by the American Medical Association (AMA) that low color temperature lighting, like the kind used in many LED bulbs, is bad for health. The AMA claims that blue light emissions can cause eye damage and disrupt sleep patterns, particularly at color temperatures higher than 3000 Kelvin. In most major cities where LED lighting is used on streetlights, the average color temperature ranges from 5000K to 6000K, including in cities like Phoenix, Arizona; Lake Worth, Florida; and Los Angeles, California. Blue light, which is also emitted from flat screen televisions, laptop computers, and smartphones, is the markedly "cooler" color spectrum that many people find difficult to look at, especially at night. It's similar in offense to the bright white fluorescent lighting commonly used in office buildings and at big box retail stores that lacks the "warm" and more soothing colors better suited for the eyes. LED lighting itself isn't the problem, but rather the type of LED lighting being used in many areas. Mark Hartman, the chief sustainability officer for the city of Phoenix, is already working on a plan to develop a warmer LED light for use in streetlights that will range in color from between 2700K to 4000k, which experts say is much better suited for nighttime illumination. "Ideally, we want low-Kelvin bulbs everywhere," Hartman told CNN about his plan. "But there is still a remarkable difference in appearance from 5000K to 4000K. The lights may be just as bright, but not as white." Avoid 'blue' light at night to improve sleep According to the group Eversource Energy, some 25 cities in Connecticut alone have already opted to follow the AMA's advice by installing LED streetlights with a color temperature of 3000K or lower. And many other cities across the country are likely to follow their lead, especially those that have yet to transition from the dark orange ones that have been a staple in cities for many years. But the risk is still present in many consumer electronic devices, especially smartphones that people use late at night before going to bed. Like with streetlights, the blue light from these devices can be damaging to the eyes, and is known to disrupt the circadian rhythm, making it difficult to maintain a normal and healthy sleep cycle. Bright white lights in general are problematic for health, especially in the elderly. Research shows that shortwave blue light scatters more in the eyes than red and yellow light, which in extreme cases can cause retina damage. Exposure to blue light has also been linked to more severe health conditions like depression and obesity. "Really bright lights can be worse for aging people," says Travis Longcore, an architecture professor at the University of Southern California who studies artificial night lighting. "Our brains are particularly sensitive to light that peaks in blue. When overexposed to high-color temperature LED lights, our circadian rhythms are more likely to be disrupted." Because it suppresses melatonin production, blue light is particularly hazardous to healthy sleep--perhaps even more so in consumer electronic products than in street lights. That's because most people don't stare directly into streetlights, but they most definitely stare directly into their smartphone, tablet and computer screens. It is advisable to limit the use of such electronics before going to bed, or to alter the color temperatures of such devices at night to make them "warmer."

An LED street light is an integrated light that uses light emitting diodes (LED) as its light source. These are considered integrated lights because, in most cases, the luminaire and the fixture are not separate parts (except LEDGine-based luminaires). New in manufacturing, the LED light cluster is sealed on a panel and then assembled to the LED panel with a heat sink to become an integrated lighting fixture. Different designs have been created that incorporate various types of LEDs into a light fixture. The current trend is to use high power 1 watt LEDs. However, some companies use low power LEDs in their products, including several low power LEDs packed together to perform the same purpose as a single high power LED. The shape of the LED street light depends on several factors, including LED configuration, the heat sink used with the LEDs and aesthetic design preference. Heat sinks for LED street lights are similar in design to heat sinks used to cool other electronics such as computers. Heat sinks tend to have as many grooves as possible to facilitate the flow of hot air away from the LEDs. The area of heat exchange directly affects the lifespan of the LED street light. The lifespan of an LED street light is determined by its light output compared to its original design specification. Once its brightness decreases by 30 percent, an LED street light is considered to be at the end of its life. Most LED street lights have a lens on the LED panel, which is designed to cast its light in a rectangular pattern, an advantage compared to traditional street lights, which typically have a reflector on the back side of a high-pressure sodium lamp. In this case, much of the luminance of the light is lost and produces light pollution in the air and surrounding environment. Such street lights can also cause glare for drivers and pedestrians. A drawback of LED focus panels is that most light is directed to the road, and less light to the footpaths and other areas. This can be addressed by the use of specialized lens design and adjustable mounting spigots.

Commercial Segment of LED Lighting Market in China holds the Highest Market Share In China, Commercial segment of LED lighting market dominates the LED market share compared to other segments. Other LED lighting segments such as Residential LED lighting market, Industrial LED lighting market and Outdoor LED lighting market is also performing well in China. Moreover implementation of LED lighting standard in china will further shift the LED lighting into high quality LED product. Due to cutting edge technology & Innovation in Led lightening products, prices of Led bulbs is gradually diminishing & reaching closer to the conventional lightening products Year on Year, due to cutting edge technology and innovation in Led lightening products, the average price of Led bulbs is gradually diminishing and reaching closer to the conventional lightening products. Therefore, as of now, the demand of led lightening products especially in residential and commercial lightening market is expanding.

For promoting high-efficiency LED lighting products, National Development and Reform Commission (NDRC) and China's Ministry of Finance (MOF) had collaborated to look after interim measures on administration of financial subsidies. The actions like financial subsidies to promote LEDs lighting is working. In the current scenario, Local governments are working more proactively in response than China's central government in implementing LED subsidies. In China, Guangdong Province, consist the largest LED industry size and has relatively higher amount of subsidies. As of 2013, Foshan in Guangdong Province, Dongyuan, Zhongshan and many other cities have launched several subsidy projects to promote LED lighting products in mass level. In the mean time, Power costs saved by LEDs are all used to subsidize construction projects in Zhongshan city.

Escalating urbanization, price cuts and local energy savings targets make the technology more tempting. Lighting items are vital to the advancement of the national economy and people's livelihood as far as livelihood is concern. Apart from that China's lighting industry has been on the rise and the country has become a leading world lighting consumer and producer date back to 20 years. Bharat Book Bureau announces the addition of the report "China LED Lighting Market Size, Volume, Share By Applications (Industrial, Outdoor, Residential, & Commercial), Companies (MLS Co Ltd., Philips Lighting, Osram, Cree Inc., Foshan Electrical & Light)" to its offering.

With the LED chip and drive power technology to enhance, plagued the LED lights cooling, light failure, power and other issues to be resolved, while the price of the rapid decline in the LED lights to enhance the cost-effective. The domestic LED lights gradually replace the traditional street lights to become the main force of the new installation of the street, while the intelligent control of street lighting features LED lighting products to strengthen the advantages. In the context of energy-saving emission reduction, LED lamp penetration rate gradually improved. (GGII) research data show that benefit from the domestic LED market collective pick up, 2016 China's domestic LED street lamp market reached 9.46 billion, an increase of 15.4%, as of the end of 2017 the domestic LED street lamp penetration rate of nearly 40% .

The lawn lamp is a kind of both lighting and beautification function of lamps, in the town a lot of need lighting of public occasions can see it. Generally speaking, most of the lawn light is solar LED lawn lamp. Advantages of the lawn lamp Caoping Deng use LED as a light source, LED long life, can reach more than 100,000 hours, the working voltage is low, very suitable for use in solar lawn light. In particular, LED technology has gone through its key breakthroughs, and its characteristics in the past 5 years has greatly improved, its cost performance is also greatly improved. In addition, LED by the low-voltage DC power supply, the light source control costs low, so that regulation of light and shade, frequent switching are possible, and will not adversely affect the performance of LED. But also can easily control the light color, change the classification of light, resulting in dynamic illusion, so it is particularly suitable for solar lawn light. Solar lawn light source and power system design methods due to the unique advantages of solar lawn, in recent years has been rapid development. Lawn light power is small, mainly for the purpose of decoration, high mobility requirements, the circuit laying difficulties, high water requirements for the site. These make the solar-powered lawn light show many unprecedented advantages. The development trend of solar LED lighting Solar energy as a new green energy, with its unparalleled advantages of the rapid promotion and application. As the fourth generation of new light source, in the city Lianghua landscaping, road lighting, garden lighting, interior lighting and other areas of lighting and applications have been effectively used. Especially in remote areas without electricity, solar lighting has a wider range of applications. Most people believe that energy-saving lamps can be energy-saving 4/5 is a great initiative, but also energy-saving lamps than the energy-saving LED 1/4, which is a great innovation solid light source. In addition, LED also has high light quality, basically no radiation, reliable and durable, very low maintenance costs and other advantages, are typical of green lighting. Ultra-bright LED successfully developed, greatly reducing the use of solar lighting costs, to reach or close to the frequency of AC lighting systems installed cost of the initial installation, and has the protection of the environment, installation is simple, safe operation, economic and energy-saving advantages. As the LED has high light efficiency, low heat advantages, has been increasingly used in the field of lighting, and presents a trend to replace the traditional lighting sources. In western China, non-main road solar street lights, solar garden lights gradually become the scale. With the vigorous development of solar lamps, "green lighting" will become a trend. Advantages and Application of Lawn The main advantages of lawn lamp for safety, energy saving, convenience, environmental protection. Suitable for residential community green grass landscaping lighting embellishment, park lawn embellishment. Several Problems of Solar Energy Combined System for Lawn (1) photosensitive sensor. Solar Caoping Deng need to light control switch, designers often use photosensitive resistance to automatically switch lights, in fact, the solar cell itself is an excellent photosensitive sensor, use it to do photosensitive switch, better than the photosensitive resistor. For a solar lawn lamp using only a 1.2V Ni-Cd battery, the solar cell module is composed of four solar cells connected in series. The voltage is low and the voltage is lower in the low light, so that no black voltage has been lower than 0.7V. Light control switch failure. In this case, as long as a transistor coupled with a direct amplification, you can solve the problem. (2) according to the level of battery voltage control load size. Solar lawn light is often a continuous rainy time to maintain a high demand, which increases the system cost. We reduce the number of LED accesses when a continuous rain-cell voltage drops, or reduce the daylighting time of the solar lawn light, thus reducing system cost. (3) solar cell packaging. At present, there are two main types of solar cell packaging, laminating and Dijiao. Lamination process can ensure that the working life of solar cells more than 25 years, Dijiao Although beautiful at the time, but the solar cell life of only 1-2 years. Therefore, the following 1W low power solar lawn lamp, in the absence of high life requirements, you can use the Dijiao package form, for the life of a solar lawn, the proposed use of laminated packaging. (4) flicker change light. On the other hand, it is possible to control the average output current of the battery by changing the flicker duty cycle, to extend the working time of the system, or to reduce the working time of the system under the same conditions. Solar power, the cost will be greatly reduced. (5) three-color color energy-saving lamps of the switching speed. This problem is very important, it even determines the life of solar lawn light, three-color-color high-performance energy-saving lamps start up to 10-20 times the starting current, the system to withstand such a large current situation may have a significant voltage drop, Solar lawn light can not start or repeated start until the damage. (6) boost the efficiency of the circuit and the impact of LED lights. Low-power solar lawn generally have booster circuit, if the oscillation circuit, inductor boost. Inductor using standard color code inductor, standard color code inductor using open magnetic circuit, magnetic flux loss, so the circuit efficiency is low. If the use of closed magnetic circuit manufacturing inductor boost, such as magnetic ring, boost circuit efficiency will be greatly improved. LED characteristics close to Zener diodes, the operating voltage change 0.1V, operating current may change about 20mA. For safety, the use of series current limiting resistor under normal circumstances, a great loss of energy is clearly not suitable for solar lawn, and LED brightness changes with the operating voltage, and must automatically limit, otherwise it will damage the LED. General LED peak current 50-100mA, reverse high-energy battery or battery load, boost circuit peak voltage is too high is likely to exceed this limit, damage the LED.

LED Lawn lamp mainly use solar energy to work, during the day when sunlight on the solar cell, the light energy into electrical energy stored in batteries, and then by the battery at night as the lawn of the LED (light emitting diode) provides power. Its main advantage is safety, energy saving, convenient, and environmental protection. Green grass for residential community beautification lighting decorations, park landscaping lawn ornament. Advantage of LED Lawn lamp Lawn use LED as a light source, LED long life, up to 100,000 hours, low voltage, very suitable for use in lawn lamp. In particular, LED technology has been a breakthrough in the key, and their characteristics has greatly improved in the past five years, its cost performance has greatly improved. In addition, LED by the low voltage DC power supply, its low cost and light control, so adjust the brightness, frequent switches are possible, and should not adversely affect the performance of the LED. You can also easily control the light color, light classification change, resulting in dynamic mirage, so it is particularly applicable on lawn lamp. Lawn light and power system design unique advantages as lawn rapid development in recent years. Small lawn lamp power, mainly in the decoration for the purpose of mobility requirements, the circuit laid difficulties, the venue for the high water requirements. This makes the solar-powered lawn show many unprecedented advantages. Category of LED Lawn lamp: Lawn lamp development so far, according to the environment and design is different, derived from a different species, divided into: Continental lawn modern lawn classical lawn theft lawn landscape lawn lamp, LED lawn lamp six categories. Continental lawn lamp: The design style resort to some European countries, European art elements, to abstract forms. Modern Lawn Light: The design style more modern artistic elements, minimalist style of performance techniques, Classical lawn lamp: its use of Chinese classical design elements to use and modifications, such as: lanterns. Three types of lawn, representing different styles, but also most of the manufacturers in order to cater to the urban building design, derived from. Theft lawn light: it is designed to eliminate some of the criminal gangs stealing lawn light on social phenomena such as trafficking, theft lawn light multi-use polymer composite materials made of its strength and corrosion resistance slightly higher than steel and aluminum, but its price expensive. Landscape Lawn Light: Landscape Lawn Light designed mostly decorative landscape main lighting functions supplement. Mostly rockery plants as the main design elements.

The knowledge of LED Projection lights Effect LED Projection lights controlled by the built-in microchip, in a small engineering applications, you can use without controller, to achieve gradual, transition, color blinking, random blinking, alternating gradient and other dynamic effects, you can control by DMX achieve chase, scan results. Applications Single building, historical buildings exterior lighting. Light outside the building through lighting, indoor local lighting. Green landscape lighting, billboard. Specialized medical facilities, cultural and other lighting. Bars, discos and other entertainment atmosphere lighting the Design of LED Projection lights With the advent of LED Projection lights source design methods and ideas to break the traditional light sources, there are two new design concepts 1. lighting scenarios: based on demand environment to design lamps. Lighting scenarios in place as a starting point, intended to create a beautiful, brilliant light environment, to heighten the effect of the scene, people feel there is a scene atmosphere. 2. mood lighting: based on human needs to design lamps. Mood lighting is people feeling as a starting point, from the perspective of people like to create a mood lighting conditions. Mood lighting and scene lighting is different, dynamic mood lighting, lighting the way to meet people's spiritual needs, people feel a mood; and scene lighting is static, it can only highlight scene lighting needs, and can not express people's emotions. Mood lighting includes four aspects: First, green energy, the second is healthy, the third is intelligent, four is humane.

LED Projection lights also known as linear LED lights and so on, because its shape is elongated, some people will call LED line lights, largely used for architectural lighting purposes, as well as to outline the contours of large buildings its technical parameters and LED lights are generally similar, with respect to the circular structure of LED Projection lights, the heat sink stripe structure of LED lights is even more to handle it. principle In the application of more LED Projection lights are basically chosen 1W high power LED tube (each LED will be made of PMMA with a high-efficiency light lens, its main function is secondary light emitted by the LED assignment), was single-line arrangement (two-wire or multi-wire arrangement be classified as LED Projection lights), the most of LED projection lamp LED tube is a common heat sink, and some manufacturers is that each LED tube placed a small radiator, its light angle generally narrow (about 20 degrees), medium (about 50 degrees), width (about 120 degrees) are three high-power LED projection lamp (narrow angle) of the farthest effective projection distance of 15-20 meters from its usual power, about 8W, 12W, 24W, 27W, 36W, such as several forms of power, and their common dimensions generally 300,500,600,1000 several, according to the actual application can choose different lengths and power density. the Type of Control High-power LED Projection lights have internal and external control modes, internal control without an external controller can be built a variety of changes modes (up to six kinds), and the outer configuration control will have to achieve outside the control of the controller before the color change, market applications are also outside the control of the majority.

led tunnel light tunnel is a lamp, and it is applied to the tunnel, workshop, large warehouses, stadiums, and all kinds of metallurgical plant, construction, etc. Place large area flood lighting, ideal for the urban landscape, billboards, building facades for landscape lighting. With the rapid development of China's road construction, highway construction scale and the number of tunnels is also growing, tunnel lighting has thus emerged such as energy, security and other problems to be solved, with the LED light source technology matures, domestic lighting industry has also carried out research and practical application in highway tunnel LED lighting applications, therefore, combined with advanced control in tunnel lighting, high light efficiency, good stability, long life light source will be a demand for a new generation and trends. Feature led tunnel lamp is a light efficiency energy saving lamps, use light-emitting diodes (LED) as the light source body, high luminous efficiency, long life, can be realized with different mirror multipurpose lighting; and by the softening process, not people blinding or other discomfort. Ballast selection overheat protection technology to ensure lamp life. Imports of high-purity specular anodized aluminum reflector material made by precise optical design, power factor greater than 0.9, Reflective, high efficiency, good transparency, energy conservation and environmental protection. LED tunnel lighting and contrast conventional LED light source is a solid state semiconductor devices, which can be converted directly into electricity to light, compared to traditional road tunnel lighting (sodium, metal halide, etc.), LED light source has the following advantages: (1) light is small: if in good thermal conditions, LED front 10000h Masamitsu bad as before 10000h light decline of 3% to 10%, before 50000h basic 30%, far lower than the ordinary road lighting, emitting more stable. (2) high color: LED color generally about 70 ~ 80, higher if the words of three-color phosphor; high pressure sodium lamp is generally 20 to 35, lower low-pressure sodium lamp, so even if the brightness of conventional light sources higher than the LED, but the visual effect is worse than the LED, "not the brightest, but see most clearly," this should be a direction LED light source application development. (3) life: LED life span than the general road tunnel lighting, now generally higher than 50000H. (4) Price: LED lamp Although the price is higher than traditional lighting high, but with the manufacturing technology matures, its current price continue to decline sharply, the high and low pressure sodium lamp price is generally set at 2,000 yuan, while its auxiliary cables, etc. price is higher than the LED cable and other expenses. In addition, LED also has a maintenance factor, good safety performance, no flicker and energy saving advantages. Case

Light-emitting diodes (LightEmittingDiode, LED) was invented in the 1960s, it is the use of semiconductor materials electrons and holes combine with each other and release energy, so that the energy band (EnergyGat,) rank changed to light-emitting display their release energy of. LED has a small size, long life, low driving voltage, low power consumption, fast response rate, good shock resistance, etc., it is widely used in signal indication, digital display and other fields. With the progress of technology, ultra-bright LED development has been successful, especially in the successful. led lamps have several advantages 1. Efficiency: the case of the same glow, LED lights than traditional energy-saving fluorescent 67%. It can effectively save money on electricity. 2. Long life: Led lamp uses energy-saving light-emitting semiconductor chip, no filament, no glass bulb, afraid of shock, not broken, the service life of up to (incandescent life of only about 1,000, ordinary energy-saving lamp life of 50,000 hours only 8,000 hours) 3. Light Health: led energy saving light line does not contain ultraviolet and infrared, does not produce radiation (high pressure sodium light contains ultraviolet and infrared) 4 green: led energy saving lamps do not contain mercury and xenon and other harmful elements, conducive to recovery, but does not produce electromagnetic interference (high pressure sodium lamps contain mercury and xenon and other elements, including electronic ballasts will produce electromagnetic interference) 5. protection of eyesight: led energy saving street light particles using DC drive, no strobe (normal lights are AC drive, will inevitably produce strobe.) 6. High light efficiency: led a small energy-saving lamps fever, 80% of the electrical energy into visible light (ordinary incandescent lights 80% of the electrical energy into heat, only 20% of electrical energy into light energy) 7. The high safety factor: led energy saving lamps required voltage, current smaller, less heat, no security risk, in mines and other dangerous places. 8. Anti-mosquito: LED lights because there is no ultraviolet light, not like a traditional fluorescent lamp to attract mosquitoes, which will help maintain a clean interior. 9. Use a worry: normal fluorescent decay few months, they need to be replaced, which caused great inconvenience; LED lights due to the long life (12 hours a day, can be used for 11 years), thus saving a lot of maintenance. LED fluorescent energy-saving: Saving than traditional fluorescent 67%. 1: power, And compared with ordinary fluorescent 40W 18W LED lamp. 18WLED fluorescent Enter the total power of 18W 40W ordinary fluorescent Enter the total power

LED (Light Emitting Diode, LED) was invented in the 1960s, it is the use of semiconductor materials Electrons and holes are combined with each other and release energy, so that the energy band (Energy Gat,) rank changes to its light-emitting display The energy released. LED has a small size, long life, low driving voltage, low power consumption, fast response rate, shock resistance Jia, etc., are widely used in signal indication, digital display and other fields. With the progress of technology, ultra-bright LED Development has been successful, especially in the successful development of white LED, making it more and more used in decorative lanterns, and even Lighting. 1 Features of Ultra-bright LED Compared with the traditional lights, super bright LED has the following advantages: 1) long life, reliable and durable, very low maintenance costs LED can be used continuously for 105h, longer than regular incandescent bulbs 100 times; 2) high efficiency can be achieved now 201m / w. 2005 is expected to reach 501m / W [1], LED) spectra of several Almost all concentrated in the visible light spectrum, the luminous efficiency of up to 80% ~ 90%, LED energy-saving lamps also energy than 1/4; 3) colorful, pure light color to 12-inch red traffic lights, for example, it uses low-efficiency 140W incandescent lamp as As the light source, 2000lm white light generated by the red filter, 90% light loss, only 2001m red, In LumiledsLighting company used 18 red LED light source design, including circuit losses into account, only consumption Power 14W, light can produce the same effect; 4) light speed car lights is an important area of application of the LED light source, the LED response speed (ns level), Install high LED brake lights on the car, you can reduce the incidence of rear-end accidents. In recent years, Bright LED has been applied in the last light of an automobile, for example, the German Audi Audi A86.O, Italy Italy Fioravanti company at the 2003 Geneva Motor Show concept car Yak, US Ford Motor Company in Detroit recently The law of Model U motor show have begun to highlight LED headlamp design. Although super bright LED has many advantages, but there are still the following disadvantages: 1) low power LED monomer market power in general 5W or less, but also no more powerful LED, which is currently LED lighting is difficult to become the biggest bottleneck of choice; 2) need to strictly control the temperature of the LED is a semiconductor material, and having a general diode as the PN junction, as highlighted two Diode power is relatively large, so the same power semiconductor devices, you need to consider the heat problem, excessive junction temperature directly Effect of LED life, and increases the LED light decline in serious condition LED will burn; 3) In addition to the high price of power is low, the price is difficult to become a major factor in LED lighting, LED although most people have now been Know, and most people are good, but its high price is difficult to be accepted by consumers, the current single yellow LED about O. 6 yuan / month, green and blue LED monomer at 1.8 yuan / month or so, the price of white LED reach 2.2 to 5.5 yuan / Month or so; if the dozens of single LED combinations, the cost will be greatly increased, as the LED mounted on a lawn lamp , The unit price is equivalent to the general lawn several times, LED light source to become the mainstream of the future of lighting, it must move Large lumen direction, will it be possible to reduce costs, the market may have a breakthrough. 2, Features of Ultra-bright LED HPWA-xH00 Lumileds Lighting Company is a super bright LED, this paper analyzes it as an example super bright LED Features. (IF) is a graph showing the relationship between the forward voltage drop (VF) and forward current of the curve shows that, when the forward voltage exceeds a certain Threshold (about 2V), that is commonly referred to after the turn-on voltage can be approximated that, IF and VF proportional. Current ultra-bright Up to the highest IF LED 1A, and VF is usually 3 ~ 4V. Since the optical characteristics of the LED is usually described as a function of current, rather than a function of voltage, luminous flux (φV) and IF Guan Line curve shown in Figure 2, therefore, the use of constant current source driver can better control the brightness. In addition, from Table 1, LED Range of forward voltage drop variation is relatively large (up to 1V above), but by Figure 1 VF-IF curve indicated, VF tiny Changes will cause large, IF change, causing large changes in brightness. Therefore, the constant voltage source LED driver can not be guaranteed Brightness consistency and impact of LED reliability, lifetime and lumen. Thus, ultra-bright LED constant current source commonly used drive. 3 Drive Circuit Due to limitations LED power level, typically to simultaneously drive a plurality of LED brightness to meet the needs, therefore, require special The gate drive circuit to light LED. Briefly describe the main circuit LED driver below. 3.1 resistive current limiting circuit 3.2 as a linear regulator Core linear regulator is to use the power transistor operating in the linear region or MOSFFET as a dynamically adjustable resistor Control the load. Linear regulators have a parallel and series two. Since the shunt regulator needs a resistor in series, the efficiency is not high, and relatively wide input voltage range of circumstances Under difficult to achieve a constant adjustment. Figure 5 (b) shows the series regulator when the input voltage switching regulator 3.3 The drive technology is not only limited input voltage range, and low efficiency. In general LED for low power driven, Since the current is only a few mA, so the loss was not obvious, when used as a current several hundred mA or more bright LED Drive, the power loss of the circuit became more serious problem. Switching power supply is the most efficient energy conversion, It can reach 90%. Buek, Boost and Buck-Boost converter can be used with equal power LED driver, only To meet the LED constant current driver, instead of using the detected output current detection output voltage feedback control. Figure 6 (a) for the introduction of the LED drive circuit Buck Converter with traditional Buek different converters, power switch S moved Back inductance L, so that S source grounded, thus facilitating the S driver, LED and L series, and the freewheeling diode D and The anti-parallel series circuit, the driver circuit is not only simple and does not require an output filter capacitor, reducing costs. but, Buck converter is a buck converter, does not apply to low input voltage or a plurality of LED series of occasions. 4 Introduction of Drive Control Chip According bright LED high-power constant-current drive characteristics, many companies have launched a special highlight LED Driver IC, For example: Melexis, lnfinton (Infineon), Lienear Technology (Linear Technology), Supenex Inc, Analog. Devices (ADI) Wait. 4.1 introduction of MLxl0801 chip MLXl0801 is Melexi8 of a public TV for automotive applications, LED driver chip, the chip can also be used to relay Etc. coil driver, and as electronic fuse. Principle MLx10801 chip block diagram shown in Figure 7, which integrates power Rate MOSFET, the maximum drive current of 350mA. When used as an LED driver that has the following characteristics: - Shao external application circuit is simple; - Internal / external temperature detection and protection; - High efficiency switching power supply drive; - You can control the brightness by PWM input; -LED Parameters can be adjusted and can be stored in on-chip NV memory. MLX10801 although only 8 pins, but powerful, Table 2 MLXl0801 pin function description. 4.2 Comparison of high-power LED driver chip A comparison of the current drive control chip performance power IED, IED in the application of high-power drive control chip, according to According to different applications to choose: 1) When the optional power devices require higher power is not integrated in the chip controller, so you can follow the actual work Rate demand individually selected power devices; 2) When you need a higher conversion efficiency, such as portable devices, choose the drive circuit of switching power supply; 3) When applied to the high reliability of the device, you can select with a temperature protection, fault alarm and other comprehensive control functions

Classification and distinction LED light bar LED lights with conventional and LED light bar is divided into two kinds of flexible LED lights, but generally also includes using old-fashioned wire connecting LED Lights, such as flat three-wire 4.3W / m, flat four-wire 6.48W / m, flat five lines 8.64W / m light zone. Difference: 1: a flexible LED light strip is made using FPC assembled circuit boards, assembled with SMD LED, the thickness of the product is only The thickness of a coin, does not occupy space; common specifications are 30cm long 18 LED, 24 pcs LED and 50cm long 15 LED, 24 LED, 30 pcs LED and so on.
