How HLD light sources for the future development trend - China lighting network

HLD light source is the vocabulary of the projector industry emerging in the last two years, actually this kind of light source is philips launched highlight LED light source. The principle of this kind of light source and LED light source has no much difference, just on the expression of brightness in contrast to the LED light source has a lot of ascension, you can understand for the HLD technology is the upgrade version of LED technology. At present, the technology more by improving the green LED luminous efficiency, thus promotes the overall brightness of the light source. HLD light source can be understand as a highlighted version of the LED light source HLD light source, to solve the traditional LED light source only up to about 1000 lumens brightness bottleneck, in addition to the micro now brought good news for product industry, also began to layout household and the education market. HLD illuminant brings pressure to traditional light bulb at the same time, also means that its officially announced and also new laser light projector in these two market segments. LED color performance ability better and close to the original image, The left side as the original, LED projection film is on the right picture) HLD light projector inherited the LED light source excellent colour performance advantages, compared with single laser light source currently on the market, both the picture performance gap is very obvious, although we often hear at ordinary times the laser light source, wide color gamut, but monochrome laser light source color accuracy is not satisfactory, the reason is monochrome laser projector with blue laser + phosphors pattern, but no blue laser wavelength optimization to the most accurate, so the color accuracy of the laser light source is not good. So the emergence of HLD illuminant, can make up for the monochrome laser light source color board. HLD technology in the field of micro cast plan this year is still in constantly optimized, most insiders predict 2018 pico projector brightness performance will be a breakthrough. In the recent news of HLD light projection products, many manufacturers launched 3000 lumens projector HLD light source products, philips said, but the future future HLD light source brightness range is 3000 to 6000 lumens, USES this kind of light source products sales market covering the education teaching, conference room, business presentations, show the application fields such as exhibition. HLD light because is trichromatic light at the same time, so on colour also has a natural advantage. HLD light source for micro investment banking industry is a big good news HLD light + 3 combination of LCD projection technology will be a future direction. The combination has the advantage of the color, because the 3 LCD projection itself emphasizes color edge, more combination with HLD light source. For the education market, the combination of HLD + 3 LCD can not only improve display effect, also more eye of HLD light source. HLD light projector is good performance ability but big volume taken together, the HLD light seems to be lost in the past LED lighting source low hat, but as the brightness, volume increase, because the ascension of the first problem is the bulb power directly increase brightness and heat dissipation problem, only by increasing the volume of the projector to solve the problem of heat dissipation of the projector. HLD light projector in addition to this, also has the problem of high cost, want to compete for bigger market, also need to constantly to meet the needs of the consumers more hard.
