LED lighting technology development

LED lighting of the prospects
　 　As the Earth's greenhouse gas emissions, a growing problem, approaching the critical point of the Earth self-regulation, countries have introduced policies, including our governments around the world need urgent implementation of energy saving (carbon dioxide), LED lamps are the most energy-efficient green electric light, natural lighting, energy saving as the main option, with the LED lighting suppliers cost and price decreases, the rate is accelerating its spread in 2020, LED lights will be more than 50% market share .
　　Reduce the cost of LED lights
LED chip occupies a major part of the cost of LED street lights, thereby reducing the LED is the main way to reduce the cost of the cost of LED chips.
LED chip technology is the key substrate and epitaxial growth technology. Sapphire substrate material from the traditional materials, silicon and silicon carbide, the development of zinc oxide, gallium nitride and other new materials. In a few years, including by means of chip architecture, the surface rough treatment and multi-quantum well structure design, including a series of technical improvements, LED in the luminous efficiency to achieve a significant breakthrough.
Low cost silicon substrate, technology advances, the luminous efficiency but also satisfied, if sustained, this growth rate, once you achieve a higher level, the silicon substrate as the main technical solutions become an inevitable choice, companies will huge economic returns.
　　Improve the light efficiency of LED lights
Improve the light efficiency can also increase effective from the ratio of light to start. Thin-film chip technology can reduce the loss of light output side, with the reflective surface of the bottom 97% of the light output from the front, making the energy conversion of light to be effective mostly light, not only significantly improve the efficiency of LED light bulbs, also for the lens design creates a superior convenience. Thin-film chip technology is ultra-bright LED chip production in the core technology.
