The prospect of 200W led Flood light lights
As the earth's greenhouse gas emissions are getting more and more serious, which approached the earth the self-adjustment of the critical point, various countries has issued relevant policies, including China, governments around the world it is necessary the implementation of energy conservation and emission reduction (co2), 200W led Flood light lamp is the most energy saving green lighting, natural lighting energy conservation and emission reduction as the main options, with 200W led Flood light lamp cost and price decreases gradually, the popularity of speed also to speed up, before 2020, 200W led Flood light lamp market share of more than 50%.
To reduce the cost of 200W led Flood light lights
200W led Flood light chip occupies the main part of the cost of 200W led Flood light lights, and reduce the cost of 200W led Flood light the main way is to reduce the cost of 200W led Flood light chip.
200W led Flood light chip technology development key lies in the base material and epitaxial growth technology. Base material from the traditional sapphire materials, silicon and silicon carbide, development to zinc oxide, gallium nitride and other new materials. In just a few years, with the help of including chip structure, surface roughening treatment and multiple quantum well structure, design a series of technical improvement, 200W led Flood light in efficacy it great breakthrough.
Silicon base cost is very low, technology in progress, but the luminous efficiency is not satisfied, if keep the speed of this evolution, once reached a higher level, the silicon base become the main technical solutions become inevitable choice, the enterprise will also have great economic returns.
Improve the 200W led Flood light light efficiency
Improve the efficacy can also improve the proportion of light from effective starting. Thin film chip technology can reduce the side light output loss, with the aid of the bottom of the reflecting surface that more than 97% of the light output from the front, which makes the power by converting light is mostly effective light, not only significantly improve 200W led Flood light efficiency, but also for the lens design create favorable conveniences. Film chip technology is the super bright 200W led Flood light chip production of core technology.
Improve the 200W led Flood light light color rendering
In the high brightness white light 200W led Flood light , a small part of the blue happen stokes shift has a longer wavelength. This is a good thing, because this makes 200W led Flood light lamp manufacturers can use many different colors of phosphor layer, thus extended emission spectrum, effectively improve the 200W led Flood light color rendering index (CRI). The white 200W led Flood light phosphors have high CRI is the price, because the stokes shift will cause the efficiency of white 200W led Flood light is lower than monochromatic 200W led Flood light efficiency. But for most of the lighting applications is concerned, would rather choose high CRI and efficiency slightly low 200W led Flood light lamp.
