SIOSUN The development trend of lighting technology

1.One of the main light source will be converted to the LED lighting

At present, the high power LED lighting for commercial products have reached more than 150 lm/W,lifespan up to 30000 hours,these make the comprehensive performance of the LED has transcended the other light sources.

Besides,in addition to the high power,LED lamps price are close to the lamp which made with another light sources.Therefore, relatively speaking, the LED has a certain advantage.At the same time, the LED lighting laboratory products have reached more than 300 lm/W, and through the reasonable heat dissipation design, the lifespan of 50000 hours is completely can be achieved.The photosynthetic efficiency and lifespan of another light sources has limited space for improvement.Therefore, can be expected that LED will become the mainstream in the lighting market soon.

2.LED device technology research will be mainly focused on the green light to promote the efficiency of LED

Core component, LED semiconductor lighting technology, the current red light LED and blue LED has high photoelectric efficiency, but the green LED photoelectric efficiency is very low.This limits the LED spectrum flexibility material application.Therefore, promote green LED lighting is the most important research topics LED device.But the current GaN LED technology route in big technical bottlenecks, both in the existing technical route and innovation of technical route to study.

3.Another study of LED device technology research will be a narrow spectrum LED device

A single LED a narrow spectral width will help achieve the infinite flexibility of assembly LED spectrum.This will make the LED application more widely.At the same time, the LED one of the main application of the LED display, if you can make the monochromatic LED the spectrum width of the smaller, will be able to achieve greater color gamut space.And this is a large application field.

4.White LED general lighting will gradually turn to RGB

Normal lighting light source are presented in the form of white light or close to white light.At present, with the highest cost-effective integrated, is also the market mainstream white LED, are the YAG phosphors are blue leds.However, RGB mode has higher photosynthetic efficiency in theory, and takes the way of RGB can make the lamps and lanterns that move light, color, and color rendering index, etc.As green light LED luminous efficiency has increased, therefore, believe in RGB mode (further extended for more than 3 or 3 monochromatic LED mixed color) will become the mainstream model of white LED.

5.Light source color rendering of the characterization of the debate will be a long process, in the form of spectral characterization may be the ultimate result.

The characterization of the parameters of the light source color rendering mainly color rendering index.But, it is based on the traditional form of limited spectrum of light source on the basis of.LED spectral infinite flexibility will make such a representation.Can be expected, if the LED to achieve the real spectrum infinite flexibility, so any kind of color rendering of the single parameter characterization will actually is flawed, the ultimate way of representation should be spectrum itself.
