The top ten trends analysis of the LED lighting technology development

The material basis of lighting technology is light source. Therefore, the development of lighting technology is based on the development of light source technology. Since the1990s years, three Japanese scientists Akasaki Akira, Amano Hiroshi and Shuji Nakamura in the GaN-based blue LED technology, which has made a major breakthrough since the rapid development of LED technology. This is also a strong impetus to the development of lighting technology, which has and will have a huge change in lighting technology including the following aspects:

1, the mainstream light source of the lighting will turn to LED

At present, high-power LED commercial products have reached the luminous efficiency of 150lm / W or more, life expectancy of more than 30000 hours, which makes the LED's overall performance has gone beyond the other light source.

At the same time, in addition to great power, the price of LED lamps have been close to other light source composed of lamps. Therefore, relatively speaking, LED has a certain advantage. At the same time, LED laboratory product luminous efficiency has reached 300lm / W or more, and through a reasonable cooling design, more than 50,000 hours of life is fully achievable. In principle, the space of other light sources to enhance the light efficiency and life is not much. Therefore, it can be expected that it should be just around the corner that LED lighting become the mainstream light source in market.

2, LED device technology research will focus on green LED efficiency improvement

The core device of Semiconductor lighting technology - LED, the current red LED and blue LED has a high photoelectric efficiency, but the green LED photoelectric efficiency is very low. This limits the substantial application of LED spectral flexibility. Therefore, to enhance the green LED light effect is the most important LED research project. But the current GaN-based LED technology line encountered a lot of technical bottlenecks. Whether it is the existing technology route or innovative technology line needs to be studied.

3, LED device technology, another study will be narrow-spectrum LED device research

The narrower spectral width of a single LED will help to truly achieve the infinite flexibility of assembling LED spectroscopy. This will make LED application prospects more widely. At the same time, a major application of the current LED - LED display, if the monochrome LED spectral width becomes smaller, it will be able to achieve greater color gamut space. And this is a big area of ??application.

4, ordinary lighting with white LED will gradually turn to RGB way 

General lighting is presented in white or near white light. At present, the most comprehensive cost-effective, but also the mainstream of the market white LED, are blue LED plus YAG phosphor way to achieve. However, theoretically RGB way has a higher luminous efficiency, and the use of RGB way will make the lamp can adjust its dimming, color, and even tone color index. Therefore, with the upgrade of the green LED luminous efficiency, I believe that RGB (further extended to 3 or more monochrome LED color mixing) will become the mainstream white LED mode.

5, the characterization of the color of the light source will be a long process of debate, and the characterized in spectral form may be the ultimate result

The parameters that characterize the color of the light source are mainly the color rendering index now. However, this is based on the limited spectral form of traditional light sources. The infinite flexibility of the LED spectrum will make this characterization problematic. It is expected that if the LED achieves true spectral infinite flexibility, then any one-parameter color representation will actually be flawed, and the ultimate representation should be the spectrum itself.

6, the application of light will include the two basic aspects : visual applications and non-visual applications 

The flexibility of the LED in terms of spectral assembly makes it possible to achieve a variety of visual and non-visual optimized applications, such as agricultural lighting, medical lighting, LED visible light communication, and so on. But relatively speaking, there are a number of issues to be solved for LED applications in the non-visual field, including: how the lighting conditions are optimized, LED prices need to be further reduced and so on. The former is a scientific problem, while the latter is the industrialization problem.

7, lighting technology and information technology will be the depth of integration, the birth of intelligent lighting

LED’s easy-to-control and itself are the characteristics of semiconductor devices, coupled with the relevance of lighting and human life. That is, there must be a lamp where human is. Lighting equipment is a very good physical carrier. Therefore, LED and information technology can be the depth of integration, will be the birth of intelligent lighting. This will be the future of LED lighting technology and an important direction of development.

8, the appearance of the lamp form will have great innovation potential

At present, most of the LED lamps and lanterns, including LED bulb, LED downlight, LED tube, etc., in the form are to meet people's spending habits. But this is not the best form of lighting machinery which needs to be studied. At least, LED lighting in the future is a lot of mechanical forms of innovation space.

9, OLED will occupy an important position in the display area

The OLED emits light in the form of a surface light source relative compared with the LED that emits light at an approximate point source. Therefore, the future of LED lighting applications (visual applications and non-visual applications) occupy the vast majority of the market. OLED still has certain advantage in the display areas.

10, natural light lighting will be taken seriously

In recent years, energy-efficient lighting, health lighting and ecological lighting has gained a lot of attention. And the use of sunlight to achieve lighting naturally becomes the best choice. Therefore, I believe that with the technological progress, natural light will gain more and more attention.

As the LED has great flexibility in the scale, spectrum, time of three space, the future development of LED may be the birth of many innovative applications and concepts, which is worth looking forward to. This is based on the development trend of artificial light source lighting. At the same time, with the green concept of environmental protection continues to deepen, natural light lighting will also have greater development.
