LED lights are the most energy-efficiency green power light source, natural lighting energy saving options, along with the gradual reduction of costs and prices of LED lights, its popularity is also accelerating. In 2020, the market share of LED ligh bulbs is over 50%. What is the influence and determination of led lamp technology development direction?
Low down the cost of LED light
LED chip occupies the main part of the cost of LED lights, thereby reducing the cost of the LED is to reduce the cost of the LED chip.
The key for LED chip technology development lies in the base material and epitaxial growth techniques. Base material is by the traditional materials of sapphire, silicon and silicon carbide, the development of zinc oxide, gallium nitride and other materials. In a few short years, by means of a series of technical improvements, including chip architecture, surface roughening treatment and multiple quantum structure design, LED light bulbs achieved a great breakthrough on the Light effect.
Low cost silicon substrate technology continue to progress, but the luminous efficiency are still not satisfied, to maintain this pace of development, once they reach a higher level, the silicon substrate as the main technical program has become an inevitable choice. Businesses will also be huge economic returns.
Improving the luminous efficiency of LED lights
Improve the light efficiency can also improve the proportion of the effective light to start. Light thin-film chip technology can reduce the light output of each side of the loss, with the bottom of the reflecting surface of more than 97% of the light from the front output power conversion be mostly light, not only significantly improve the LED light bulbs luminous efficiency, a favorable conditions for the lens design. The thin-film chip technology is the core technology of super bright LED chip production.
Improving the color of the LED Tunnel lights
In the high-brightness white LED, a small portion of blue stokes shift of the longer wavelengths. This is a good thing, because it makes the LED light manufacturers that can use many different colors of the phosphor layer to extend the emission spectrum, effectively enhances LED color rendering index (CRI).
