ED lighting applications in the past, the main architectural landscape lighting, such as garden lights (Path light), Searchlight (Floodlight), step lights (Step lights), balcony lights, accounting for the overall LED lighting market in 2008 to about 43%, but this The growth of the field has become a slow, emerging growth areas of the future promising, outdoor applications that LED lights, its growth potential can not be ignored, because of the global number of street lamp device has reached 180 million, and China, the United States and other countries are more active use of the type lights. Indoor application is based on the fastest-growing retail display lighting, the next three years, the growth rate will remain above 5 percent. As for the much-anticipated home lighting, home lighting due time each day an average of about 4.3 hours, LED lighting manufacturers, power-down feature that can be created by the lack of benefit from the use of the limited time, can only look forward to greatly enhance the LED bulb / luminaire efficiency and guide light bulb / lighting costs decreased rapidly in order spread to the general households. 1 illumination characteristics. Limit the significance of parameters (1) to allow power Pm: allows you to add to the positive DC voltage across the LED with a maximum current flowing through it the product of. More than this value, LED fever, damage. (2) The maximum forward current IFm: allows you to add the maximum forward current. Exceeding this value can damage the diodes. (3) The maximum reverse voltage VRm: the allowed maximum reverse voltage applied. More than this value, the light emitting diode may be breakdown. (4) Working environment topm: light-emitting diodes with a working temperature range. Lower or higher than this temperature range, the LED will not work, efficiency is greatly reduced. Without changing the premise of the material in the LED limits, higher brightness means is to increase the current, as the current increases, LED heat will soar. Used LED light source portable projector, or micro-investment of friends, we all understand, LED light source projector, very hot, and generally there will be significant noise. These products, small body is one thing, the key is large due to its own heat. With the increase in power, LED heat dissipation becomes more and more prominent, a large number of practical applications show that, LED lighting technology, LED input power can not increase the basic reason is due to the LED during operation will release a lot of heat, so that the tube die junction temperature rises rapidly, the thermal resistance increases. The higher the input power, LED lighting board, the greater the heating effect. At elevated temperatures will lead to changes in device performance and attenuation, non-radiative recombination increases, the leakage current of the device increases, the growth of the semiconductor material defects, LED lighting, metal electrode migration, yellowing epoxy encapsulation, etc., seriously affecting the LED's optical parameters. And even the power LED failure. Thus, for LED devices, reduce the thermal resistance and junction temperature, thermal properties of light emitting diodes research seems increasingly important.
