Expert interpretation: LED indoor lighting call how true?

LED has great potential for development in the field of indoor lighting. Since the introduction of white light LED, LED lamps like magnets in general for indoor lighting, especially indoor commercial lighting has a huge appeal. With the development of modern commercial, LED lighting applications in more and more industries, indoor commercial lighting has become an essential element, the field of indoor lighting becomes an important aspect of the future development of recognized LED.

What is the application and Prospect of LED in indoor lighting? Faced with the development trend of LED indoor lighting, we are encouraged, but also to think about how to maintain LED in the field of indoor lighting healthy and orderly development? The day before, journalists are generally concerned about employment issues within, interviewed the researcher Chinese aviation industry planning and Design Institute and Professor Ren Yuan will China Building Construction Science Research Institute of optical research director Professor Li Tienan.

Development of LED indoor lighting, to play a good LED advantage

With the development of lighting source, many light sources have been successfully applied in indoor lighting. With the development of a new generation of light source, LED, its unique advantages, such as light efficiency, color temperature and life expectancy, make it a new star in LED indoor lighting. (Table 1)

So, in the indoor lighting, LED and traditional lamps, its application prospects?

Professor Li Tienan believes that the purpose of lighting applications is to get a good light environment, the ability to apply LED or to rely on his suitability to see the final results. We choose different light sources and lamps to match these lighting places, so that the product can meet the lighting needs, it is necessary to compare the performance of various light sources, life and other aspects. LED has many features and advantages, but there are some performance and the needs of the site does not adapt, and LED is not the most stable, the most mature stage. LED has its own application, but not all of the lighting places are replaced by LED light source. Maybe one day, LED to the other light source replaced, but the premise is that LED must show characteristics, are superior to all other sources of good price, and outstanding effect of light environment and atmosphere shaping ability.

Ren Yuan professor believes that the current development of LED indoor lighting has many advantages, the development of better prospects. Semiconductor light-emitting diode (LED) has a history of more than and 40 years, to the first half of the last century, the study of the emergence of the blue light LED, and soon solved the white LED. The advent of white LED and its fast development, all kinds of lighting companies to the attention of the world, invested a lot of money, a very fruitful research, more than and 10 years, the luminous efficiency of white LED increased nearly ten times, as a new type of solid light source (SSL) into the lighting field, to become the second generation (the gas discharge lamp) third generation light source after the.

In yuan will Professor White LED for nearly 15 years, the speed of its development, more than expected, as a supernormal development of the juvenile "child prodigy", by cultivation and pay special attention to the family and society. Its main advantages and characteristics are:

(1) the light effect increased rapidly: right now, the practical light efficiency can reach 70 ~ 90lm/W, according to reports, the laboratory data of 160lm/W, and there is an increasing trend, expected in the next 3 to 5 years, practical optical efficiency is up to 150 ~ 200lm/W is possible, is likely to become the most efficient light source at that time.

(2) the starting performance is good, fast and reliable, only the millisecond response time, to achieve full luminous output.

(3) light adjustment is convenient and controllable.

(4) shock resistance, good weather resistance, long life.

(5) mercury free, environmentally friendly.

(6) LED in a certain angle beam directional radiation, used for lighting, lights and lamps, is conducive to the improvement of downshot flux ratio.

(7) for landscape, decoration, advertising, signal and other occasions, there are a variety of color light LED, plus a good start and dimming performance, easy to realize digital control, to achieve the colorful and dynamic changes in the commercial and recreational places very xuanranxing.

Professor Yuan seems to be in, LED is still in the continuous development of indoor lighting space is broad, the future application prospects are bright. But there is a greater progress and the corresponding research, exploration, and create conditions for the application. To further improve the efficiency of light and color, the color is more suitable for a variety of research; the semiconductor lighting organic combination of disciplines and disciplines, in-depth study for the characteristics of LED lamps form and light distribution system to further reduce costs.
