According to the report of Physicist organizational network, a new manufacturing technology is expected to significantly reduce the cost of production of light-emitting diode and to further promote the popularity of the process.
Silicon is a standard semiconductor materials with large size, low cost, easy processing, good electrical conductivity, excellent conductivity, and performance. However, technical difficulties is different coefficient thermal expansion of silicon and gallium nitride, and vulnerable to stress during the manufacturing process, resulting in uneven and rupture of the film, so it has not been able to widely available in the led production lights cracking phenomenon. Through a special process, the new technology is not only avoided the cracking phenomenon, but also make the new LED Lights stable and bright and are well suited for high-power solid-state lighting.
LED STREET LIGHT is an energy efficient lighting solutions, and considered as the most expectation to replace traditional light sources. So far, however, the cost of LED production have been higher than other more sophisticated lighting products. So it has not been widely used in daily life. Through the use of new technology, LED production is expected to spend a larger piece of silicon, which will be a major upgrade of the efficiency of led production lights.
With its technology, OSRAM has been successfully produced high -performance LED wafer with a diameter of 150 mm(6 inches). Researchers have begun to adjust the production process to manufacturer 200 mm(8 inch) wafer. This will further increase the number of chips on each substrate, reduce production costs. It is understood that the LED industry, mostly 50 mm(2 inch) or 100 mm(4 inch) as the substrate base. Such as silicon GaN technology can save at least 75% of the cost of raw materials.
At present, this film based on the new LED High Bay is still in the prototyping stage. It will be reality environment reliability test. Preliminary experiments showed that the technology made of blue and white silicon-based LED, which can achieve the performance and market products that are similar to the sapphire substrate. They estimated that the first commercial led production lights using the technology will be appeared within the two years after listing.
