LED lighting happens to be used in frozen food in the lighting. LED lamps and lanterns a number of other semiconductor machines are enough have high luminous efficiency, long period of time and low hot and cold temperature. And low efficiency of the lighting lamps and lanterns, except for shine and energy consumption outside, which produces a large cooling will likewise need the refrigerator to cooling system, which can cause the waste electricity. Irish Nualight company said, with the most effective light source to light up the actual meals is very interesting. Currently retail food lighting market value, to $1 billion. Retail food lighting market is actually going to a promising segment. Nualight company in the past few years average annual growth rate in excess of than 100% was. Liam pointed out that, so far, to pay more is the fridge freezers and configuration of the lighting system. Hope in LED lighting uses of freezers instead of a fluorescent lamp. In recent years, including wal-mart, Telco,, Roger and SUPERVALU, large global food retailers, is the actual world frozen food with fluorescent lighting replaced ark LED, save energy as high as 70%. 3, LED source of light in the KTV room of application KTV rooms lamp would be belong to a class of stage lights, with domestic economic level growth, people entertainment also more and many more rich, pay a visit to the pub KTV rooms K song is capacity the most familiar way of leisure, entertainment, the general KTV cabins indoor decoration has personalized needs, so a lot of KTV rooms operators possess to carry on with with little question of The Times, often to the KTV rooms local or decorate afresh, thus i know it can also be generated the is bestowed upon a sort of equipment for KTV rooms, KTV rooms lamp will belong into 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, a whole lot of is really a common stage lighting, including moving head light, scanner light, wizard light, laser, design lanterns again, scanning type of 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 can be a big 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 . 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 effect. KTV room lamps Features: KTV room lamps for KTV rooms itself characteristic is you will of the decision, standard KTV cabins every day to continuous business 12 hours or so, very long of use, with lamps and submit the performance of high demand, so KTV room lamps must durable. 2 It is lamps and effect of personalized design, the variety of many KTV rooms are usually in decorating a respect to pursue personalized, in order to lead the tide, attract consumers. 4, the subway tunnel lighting Because among the subway underground operation in year, equated with beacon have very popular. It requires the saving electricity, high brightness, the long life, must ensure uninterrupted lighting. However, the widely used incandescent lamp, fluorescent, high-pressure sodium lamp and etc all a few shortcomings, just about be some hard evade lighting incorrect doing. In contrast, LED with environmental protection, energy saving, long service life, high efficiency, no radiation as well characteristics, prolong service life and lessen energy expenditure. And, LED characteristics of strong vibration resistance are highly suitable for metro operation environment, can in 67 without replacement, LED lamp can effect comparing common fluorescent lamp nearly 50% higher. Therefore, the LED is getting the best green lighting lamps and lanterns. The subway station using LED lamp, cannot only save heaps of electricity, and can certainly save basically lot within the cost of maintenance. In the same time, also can ensure fairly of lighting products. LED lighting in the subway complications existing the particular system, as well as 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 akin to 50 cases. Train transformation total fee as high as $50000, but saving of control the movable parts and the upkeep cost almost three years to recover costs, so in Beijing Metro is anticipated to consist large-scale promotion. According to information, ED and semiconductor lighting says, is completely different from common energy-saving lamp of a new generation of lighting technology. May be the test G432 train. Associated with the train 168 a fluorescent lamp will change entirely for LED a shine. Relative to fluorescent lamp each 5 or 6 yuan price, the new replacement of LED lighting market price as high as 300 yuan. Current test project belongs to your National '863,' and the scientific and technical content, temporary manufacturers, free. Four, lighting use LED packaging development trend 1, COB packaging COB, each morning electronic manufacturing and isn't a new technology, involved with to point to directly along with the extension of naked in the circuit board, and will lead/welding line directly inside of the PCB's gold-plated welding line, is also commonly known as 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 assembly. LED industry in, capsicum is derived from modern science products as well as more more exquisite frivolous and portability, in addition, to get able to to reduce expenses than one LED chip design of your system board space problems in high power LED system requirements, he developed directly linked to chip the particular system board COB computers. The advantages of the COB are: the high cost benefit, line is simple in design, save the unit board space and so on, but there is also a chip integrated brightness, mixed color temperature and system integration technology threshold. With 25 W LED for example, normal 25 W high power LED light source, end up being used in 25 of your 1 W LED chip packages into 25 single LED components, and COB polymorphism is a 1 W will be 25 LED chip packages in one chip, so need two optical lens will 25 pieces from reduced to one piece, help narrow the sunlight source area, reduction material, system cost, then it could actually be simplified light source is second optical design and save assembly manpower cost. In addition, high power COB encapsulation very single high power Triggered replace more than one 1 w (including) above LED encapsulation, make product volume more frivolous short. 2, high pressure LED In precisely the same output power, high pressure LED the drive currently significantly lower than low voltage LED. Pertaining to instance the wafer of photoelectric high pressure blu-ray 1 WLED, for example, good pressure drop as almost as much as 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, therefore the same output power within the high pressure at work of LED dissipation capability is cheaper than the cheaper voltage LED, this makes certain that the associated with aluminum shell heat could be greatly decrease. High pressure LED can dramatically reduce AC-DC conversion efficiency departure. With 10 W power output for example, in case the positive pressure drop for 50 V 1 W high pressure LED, the output get 2 and 4 string of configuration, four series LED the positive pressure drop for 200 V, a lot more places just inside the 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, as a result 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 the transformer can be greatly improved, which can dramatically reduce AC-DC when converting the skills loss, the heat consumption high blood pressure the cost of further reduce heat dissipation shell. Therefore, such as using ruthless LED to flourish general lighting lamps LED products, overall power consumption can be reduced greatly, and has reduced to heat dissipation shell design requirements, such as we use the thin lighter more aluminum enclosures can satisfy the demand LED lamps and heat, because purchasing price of aluminum shell heat is LED lighting lamps major cost part of aluminum shell cost effective to reduce also is why overall LED lighting lamps and lessen cost. This show, ruthless LED might bring the LED illumination lamps and weight of however to lessen cost, but the more important significance end up being to significantly reduce the heat for the design on the system requirements, and cleared the LED lighting lamps strong enter indoor lighting market of the biggest hurdles. Therefore, high pressure are dominated coming from the future LED LED general lighting lamps market. 3, AC LED With high efficiency and energy saving, green environmental protection, the endurance for brand new characteristics of LED lighting technology now's speeding up the development, software of new technology, new project additionally be emerging. LED lighting design can be combined with light source characteristics, for example the light source, cold light and color directional change, will become the mainstream market will lighting. Current years, just like material selection, LED grain process, encapsulation structure design technology, as well as other aspects belonging to the research advances, a new exchange light emitting diode (AC LED technology arises at the historic moment, by a new idea, promote the LED lighting technology and economical. The traditional LED is usual of and may provide a voltage DC device, in some way in our daily lighting use power source is high voltage AC 100 ~ 220 V) use, must pass a transformer or switch power supply step-down, then will exchange (AC) transform into dc (DC), to change into a constant DC current source, can use for LED light chief constituent. So in LED lights are found to hold the space to put this converter, go up against the lighting design and miniaturization. And the progres of the computer based for the link, energy there end up being a certain quantity of defeat. DC in LED ac/DC switch between about 15% to 30% of the electric power be loss, the efficiency of your system had to do upwards of 90%. If can exchange (AC) direct drive LED light source to shine, and system application plan will greatly simplify. The efficiency for the system seem very easy above 90%. Transform the existence of the traditional device cause LED lighting products the high cost of the important factors that restrict LED light products the bottleneck of life, can't reflect the characteristics of LED long reality. AC LED is equated with the traditional DC LED, it should not after the AC/DC conversion, which could be directly plugged in 220 V (or 110 V) alternating electric current use of LED lighting technology. AC LED source of light is solution technology of grain in the package LED special arrangement combination technology, at the same time use LED PN junction of diode characteristics and make rectification, the actual semiconductor fabrication process will more grain integration in a single chip, namely high power single grain (single power chip) LED technology, and the staggered arrangement of the matrix technology bridge type circuit, earn the AC current can be double guide line, realize to come alive. The arrangement of the grain size as shown in figure 1 shows, the picture 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 trade body in again after shine, so therefore only require the two lead into supply that could work exchange gleam.
