Over the past few years, prospect of LED develops fast but the household popularity of the process is very slow. "This is not just a price, production or other issue. In addition to consumer recognition problem, there are a number of technical bottleneck." According to the China Illuminating Engineering Society director Wang Jinsui introduces, this leads to a commercially available track led lighting beans gall lights, LED down light, LED lamps, compared with traditional lamps, it still has very big difference, fass less well than said.
At present, the domestic market oriented with Trinity form of LED products. One of the three major key elements: source, drive power, heat dissipation. The light source is the part of the core products, chip technology mastered by Europe and the United Stated and Japan. Most domestic enterprises adopt buy the assembling way. Therefore, although the LED illumination threshold is not high, yet if you want to do well, it is necessary to solve two key problems--heat dissipation, driving power supply. In contrast, drive power challenges focused on outdoor lighting environment, while heat dissipation is for home used light to enter a large obstacle. According to industry sources, in Zhongshan Ancient Town, there are many LED assembly business, simply to put the track led lighting source assembly into the traditional lamp. Heat, light and a two optical design is not just as one wishes. Life span can not obtaion the ideal value also.
LED cooling is not good, which will cause the light, and life span shorten. In the current exhibition, the reporter found that the technical problems have had new breakthrough. From the friends of Shenzhen completely subverb the ordinary LED heat, they first introduce the new fin type LED interior lighting series, modeling include ceiling lamp, cast light lamps. According to its general manager, it can save aluminum 4% or more above. The weight is the 1/3 of the traditional lamps. Through more efficient heat conduction and heat radiation, in order to meet the domestic LED relability and life requirements. According to several hundred watts of power LED heat problem, a new research -- micro slot cluster compound phase-change cooling technology, become this year's show is a prominent spot in this study.
