LED lights are currently doing work in frozen food in the lighting. LED lamps and lanterns and other semiconductor devices are sufficient have high luminous efficiency, long period and low setting. And low efficiency of the lighting lamps and lanterns, except for shine and consumption outside, which makes a large cooling will also require the refrigerator to cooling system, which may be cause the waste vitality. Irish Nualight company said, with the right light source to light up the dish is very important. Currently retail food lighting market value, to $1 billion dollars. Retail food lighting market will certainly be a promising store. Nualight company in the last number of years average annual rate of growth of a lot more 100% turned out to be. Liam pointed out that, so far, to pay more may be the fridge freezers and configuration of the lighting software program. Hope in LED lighting applying freezers fluorescent bulb. In recent years, including wal-mart, Telco,, Roger and SUPERVALU, large global food retailers, operates a frozen food with fluorescent lighting replaced ark LED, save energy as high as 70%. 3, LED light source in the KTV room of application KTV rooms lamp would be to belong to a class of stage lights, with domestic economic level growth, people entertainment also more etc rich, go to the pub KTV rooms K song is one kind of the most frequent way of leisure, entertainment, the general KTV cabins indoor decoration has personalized needs, so an associated with KTV rooms operators keep up with the trend of The Times, often to the KTV rooms local or decorate afresh, thus sculpt be produced the belongs to a regarding equipment for KTV rooms, KTV rooms lamp will belong for the KTV room lighting sound category. TV room lights classification: KTV room lights to press utility cent could be divided into a, performing arts of light, this brand of is a common stage lighting, including moving head light, scanner light, wizard light, laser, design lanterns again, scanning regarding three claws fish, eight claw fish, lanterns bimonthly, arrows and energy-saving lamp magic ball, lighting, rain light, led palmer lamp, the console, small machine, etc. The manufacturing atmosphere effect, and second is the environment of lighting, LED lighting palmer lamp, energy-saving fluorescent tubes, wall lamp, droplight, desk lamp, explosion-proof lamps, ZiGuangDeng etc, on environmental lighting effect. Three is decoration class, have LED background curtain, LED channeling light, lighting, LED guardrail tube, article LED lights, LED floor brick, acrylic light box, etc, on environmental adornment effects. KTV room lamps Features: KTV room lamps for KTV rooms itself characteristic is you are going to of the decision, total KTV cabins every day to continuous business 12 hours or so, lengthy time of use, with lamps and submitted the performance of high demand, so KTV room lamps must durable. 2 It is lamps and effect of personalized design, the form of many KTV rooms have been around in decorating a respect to pursue personalized, so spend money on lead the tide, attract consumers. 4, the subway tunnel lighting Because belonging to the subway underground operation in year, compared to beacon have very popular. It requires not only saving electricity, high brightness, the long life, must ensure uninterrupted lighting. However, the used often incandescent lamp, fluorescent, high-pressure sodium lamp and and much more all have some shortcomings, it will likely be some hard to avoid lighting fault. In contrast, LED with environmental protection, energy saving, long service life, high efficiency, no radiation some other characteristics, prolong service life and decrease energy utilization. And, LED characteristics of strong vibration resistance are very suitable for metro operation environment, can perform in 67 without replacement, LED lamp can effect comparing common fluorescent lamp nearly 50% higher. Therefore, the LED is the best green lighting lamps and lanterns. The subway station using LED lamp, cannot only save lots of electricity, nicely can protect your an involving the associated with maintenance. In the same time, also can ensure the length of illumination. LED lighting involving subway the problems existing in the system, and gives a new structure, low cost, long service life, power saving effect is good, high reliability of subway lighting scheme. According to expert estimates, although the LED lamp is expensive, but the common fluorescent lamp is equivalent to 50 moments. Train transformation total fee often $50000, but saving of the electricity as well as the maintenance cost almost three years to recover costs, so in Beijing Metro is predicted to deemed large-scale offer. According to information, ED and semiconductor lighting says, differs from common energy-saving lamp of a particular new generation of lighting technology. Could be the test G432 train. Inside the train 168 a fluorescent lamp modify entirely for LED lights. Relative to fluorescent lamp each five or six yuan price, the replacement of LED lighting market price as high as 300 yuan. Current test project belongs to the National '863,' and the scientific and technical content, temporary manufacturers, free. Four, lighting use LED packaging development trend 1, COB packaging COB, in the electronic manufacturing and isn't a new technology, it is point to directly coupled to the extension of naked inside of circuit board, and will lead/welding line directly in the PCB's gold-plated welding line, is also commonly named the lineup (Wire bonding), again through the glue sealing technology, effective will IC manufacturing associated with the steps to the circuit board packaging transfer directly gathering. LED industry in, because modern day science and technology products more and many more exquisite frivolous and high portability, in addition, to be able to save more than one LED chip design with the system board space problems in high power LED system requirements, he developed directly linked with chip your system board COB solution. The a look at the COB are: the large benefit, lines are simple in design, save the mother board space and so on, but there is also a chip integrated brightness, mixed color temperature and system integration technology building up a tolerance. With 25 W LED the example, may 25 W high power LED light source, should be used in 25 of the 1 W LED chip packages into 25 single LED components, and COB polymorphism can be a 1 W will be 25 LED chip packages in a lone chip, so need two optical lens will 25 pieces from reduced to just one piece, assist you to narrow light source area, reduction material, system cost, then it might be simplified light source is second optical design and save assembly manpower cost. In addition, high power COB encapsulation very single high power Resulted in replace two 1 w (including) above LED encapsulation, make product volume more frivolous transient. 2, high-pressure LED In exact same holds true output power, high pressure LED the drive currently significantly not up to low voltage LED. Just as wafer of photoelectric questionable blu-ray 1 WLED, for example, the positive pressure drop as almost as much ast 50 V, i.e., just 20 mA drive current can output 1 W power, and ordinary positive pressure drop for 3 V 1 WLED, need 350 mA drive current can output 1 W power, so the same output power for the high pressure at work of LED dissipation capability to is cheaper than time voltage LED, this will mean that the associated with aluminum shell heat can be greatly diminished. High pressure LED can dramatically reduce AC-DC conversion efficiency decline. With 10 W power output for example, if the positive pressure drop for 50 V 1 W ruthless LED, the output consider 2 and 4 string of configuration, four series LED the positive pressure drop for 200 V, the actual just through your utility 220 V an alternating current (AC) use bridge rectifier and drop 20 5. But if we adopt positive pressure drop for 3 V 1 W low-voltage LED, even 10 string together positive pressure drop also but 30 V, is actually why from 220 VAC utility the buck need to 30 VDC. We know, the input and output differential pressure is lower, the AC to DC conversion efficiency is higher, visible because using high-pressure LED, the efficiency of your transformer can be greatly improved, which can dramatically reduce AC-DC when converting the ability loss, the heating consumption and reduce the price further reduce heat dissipation shell. Therefore, regarding using ruthless LED to create general lighting lamps LED products, overall power consumption can be reduced greatly, and has reduced to heat dissipation shell design requirements, regarding we use the thin lighter more aluminum enclosures can satisfy the demand LED lamps and heat, because weight loss programs aluminum shell heat is LED lighting lamps major cost a part of aluminum shell cost effective to reduce also means that overall LED lighting lamps and reduce the cost. This show, high-pressure LED can bring the LED illumination lamps and weight of keep in mind to reduce the cost, however the more important significance is to significantly reduce the heat on the design of the system requirements, and cleared the LED lighting lamps strong enter indoor lighting market of the most popular hurdles. Therefore, high pressure will be dominated by the future LED LED general lighting lamps market. 3, AC LED With high efficiency and energy saving, green environmental protection, the longevity for fresh characteristics of LED lighting technology might be speeding down the development, the usage of new technology, new project is also emerging. LED lighting design can be combined with light source characteristics, try not to light source, cold light and color directional change, will become the mainstream market will picking. In recent years, as in material selection, LED grain process, encapsulation structure design technology, and other aspects with the research advances, a new exchange light emitting diode (AC LED technology arises at the historic moment, by the right idea, promote the LED lighting technology and worthwhile. The traditional LED is normal of over the voltage DC device, not directly in our daily lighting use power source is hollywood AC 100 ~ 220 V) use, must pass a transformer or switch power supply step-down, then will exchange (AC) transform into household power (DC), to change into a continuing DC current source, make use of for LED light root cause. So in LED lighting is found to use the space set this converter, go with the lighting design and miniaturization. And the progres of the system based through the link, energy there end up being a certain amount of defeat. DC in LED ac/DC switch between about 15% to 30% from the electric power be loss, the efficiency of the product had in order to do more than 90%. If can exchange (AC) direct drive LED light source to shine, and system application plan will greatly simplify. The efficiency belonging to the system can be very easy above 90%. Transform the information on the traditional device cause LED lighting products the cost of crucial factors that restrict LED light source products at the moment are the bottleneck of life, can't reflect the characteristics of LED long your lifetime. AC LED is unlike the traditional DC LED, it will never after the AC/DC conversion, which could be directly connected 220 V (or 110 V) ac use of LED lighting technology. AC LED source of light is the key technology of grain in the package LED special arrangement combination technology, at the same time use LED PN junction of diode characteristics advertise rectification, while using semiconductor fabrication process will more grain integration inside a single chip, namely high power single grain (single power chip) LED technology, and the staggered arrangement of the matrix technology bridge type circuit, resulted in AC current can be double guide line, realize to light. The arrangement of the grain size as shown in figure 1 shows, image quality on the left is AC LED grain the staggered arrangement of matrix diagram, right picture is actual AC LED grain arrangement photos, AC LED grain in exchange body in again after shine, at which point only require the two lead into supply that perform exchange radiance.
