LED lighting shell non-metallic how long the road?

The present most leds are used aluminum plate, aluminum plate between the welding surface and radiating surface in order to solve the circuit and thermal insulation, compression body, among them with an insulating layer of epoxy resin, although solving the problem on the electrical properties, but directly LED to the thermal resistance increase, from a certain degree of influence to limit the life span of the product. For this, ceramic film technology arises at the historic moment, seems to have a want to replace the aluminum substrate, the implementation of the large-scale application of momentum. 
At present, most of the LED lights are used aluminum plate, such as insulating layer is epoxy resin cause of heat dissipation is not high question; Light failure rate is higher due to short of theoretical service life of life; Stroboscopic is also common, many products on the market, color rendering index below 80 in the China national standards; Adaptive voltage narrow range and other technical defects. 
There are companies launched a new thermal conductive ceramic film LED lights series effectively solve traditional lamps and lanterns and existing deficiencies LED lights above and on the product performance achieved six revolutionary breakthrough, namely: the droop smaller; Use more security; Products more environmentally friendly; Longer service life, applicable range is wider; Energy saving is more outstanding. 
Recently, the reporter called the general manager of JiTai XiKe, he said "ceramic phragmoplast technology instead of aluminum sheet and aluminum shell, LED tube directly welding on ceramic substrate, and then put the ceramic welding on the aluminum plate base board, the above two processes can get rid of the epoxy resin and the effect of thermal conductive adhesive, reduce LED thermal resistance greatly. With aluminum base plate with aluminum shell technology ceramic film on the cooling performance more obvious advantages. At the same time, the use of ceramic membrane technology production of lamps and lanterns as small heat resistance, temperature rise is small, greatly extend the life of a LED lamps and lanterns, there are both electrical insulation and thermal conductivity of thermal conductivity ceramics performance, have a combination of rigidity and corrosion resistance and conform to the eu limit of hazardous substances (RoHS) directive and environmental protection requirements." 
XiKe, according to this way of JiTai through research and development and the production has just entered the LED field, research on ceramic substrate and there are many process need to be examined, and the use of ceramic membrane technology in the production of LED lamps and lanterns capacity also is not very big. 
Industry experts also said that the ceramic film forming technology is introduced into the production of LED lamps and lanterns, instead of aluminum board and aluminum shell, save epoxy resin and thermal conductive adhesive, on the heat dissipation performance indeed performed better than aluminum substrate. But in the current domestic ceramic membrane technology research and development level, in the application process of LED lamps and lanterns is not enough mature, intervention to achieve large-scale alternative aluminum plate LED lamps and lanterns also need a long way to go. 
XiKe said, ceramic film technology is indeed still has a lot of technology needs further technology breakthrough, of JiTai also want to want to do something in the field of LED, their goal is to achieve the LED lamps and lanterns of internal cooling body comprehensive nonmetal. For the future prospects of the development of LED industry, LED is the best alternative future after incandescent lamp, energy-saving lamp light source, but the LED products on the market are of variable quality, the quality problems have had a lot to do with the power and cooling technology, at the same time, the product smooth effect, the price is high, the lack of standard problem solved, such as LED lighting must be the development direction of future lighting. So, in the LED industry prospects but period case, ceramic substrates in the application of the LED lamps and lanterns is just the beginning, the future in order to achieve the LED lamps and lanterns of internal heat dissipation body non-metallic still a long way to go. 
CSA Research pointed out that in terms of the present domestic Research and development level, compared with ceramic film technology aluminum plate due to the complexity of the process, so the cost will increase, on the material and the aluminum plate price. On ceramic substrate technology also need larger technical improvement, in the future for application technique of ceramic substrates is relatively mature, the LED will realize non-metallic cooling inside the lamp body, on the material cost and performance will highlight its advantages.
