In recent years, LED technology has continuously made new breakthroughs. In 2006, it was reported internationally that the LED has a luminous efficiency of more than 130 lm/w at a current of 20 mA, and the luminous efficiency of a 1 watt LED at a current of 350 mA can reach 100 lm/w. This will provide solid technical support for LEDs entering the lighting field. At present, LED is a key moment in the field of lighting. The three major international lighting groups: Philips, GE, and Osram have invested heavily in the development of LED technology and industry. Japan, South Korea, and Taiwan also vigorously promoted the development of the LED industry, and achieved good results, occupying the world's current major market share. In recent years, relevant Chinese authorities and some local governments have also attached great importance to the development of the LED industry, and have given great support in policy, investment and encouragement of the LED market , and achieved effective results.
With the gradual development of LED lighting fixtures, LEDs have gradually replaced some traditional light source products in public places such as lighting engineering auxiliary lighting. The LED is mainly composed of monochromatic light. Although the power is small and the price is high, the reliability is high, the control is strong, and the volume is small. Therefore, the first emerging market is the indicator light of the electronic device. The market has certain recognition and acceptance of LED lighting products. In 2000, LED began to enter the mainstream lighting popularity in developed countries. Nowadays, it seems that in our country, the road to popularization has begun.

The market dynamics of LED lighting have to go through three stages
1. The LED lamp replaces the acceptance stage. In the case of consistent use with traditional light sources, the characteristics of LED lamps are: low carbon environmental protection, energy saving, long life, etc., making the market easy to accept it. Especially in commercial occasions, it is the product quality advantage.
2. In the practical stage of LED lamps, on the basis of the previous stage, the market has certain recognition and acceptance of LED lighting products. Other features such as environmental protection, small size, and high reliability of LED lamps have gradually emerged. The lighting industry will also have a larger and wider development and application space. The light source is no longer just a lighting effect. As urban culture construction is increasingly valued, the streets have been decorated with lights to beautify the city.
3. Intelligent control stage of LED lamps. With the development of new technologies such as networking, LED as a semiconductor industry will also take advantage of this high-speed train to play its high controllability. From home to office buildings, from roads to tunnels, from cars to walks, from auxiliary lighting to main lighting, intelligently controlled LED lighting systems will bring a higher level of service to humans. The LED lighting industry will also go from making products to designing products to providing a total solution.
Energy saving
According to the data, because the LED is a cold light source, the semiconductor lighting itself has no pollution to the environment. Compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. At the same brightness, the power consumption is only 1/10 of that of an ordinary incandescent lamp and 1/2 of a fluorescent tube. If we replace 50% of our current traditional lighting with LED, the annual electricity saved in China is equivalent to the sum of the power generation of a Three Gorges Power Station, and its energy saving benefits are considerable.
Health
It is a green light source. DC drive, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong directionality; good dimming performance, no visual error when color temperature changes; cold light source generates low heat It can be touched safely; these are not possible with incandescent and fluorescent lamps. It not only provides comfortable lighting space, but also satisfies people's physiological health needs. It is a healthy light source that protects vision and is environmentally friendly.
Artistic
Light color is the basic element that constitutes visual aesthetics, and is an important means of beautifying the living room. The choice of light source directly affects the artistic effect of the light. LED shows an unparalleled advantage in the artistic display of light color display lamps; currently the color led product has covered the entire visible spectrum range, and has good monochromaticity, high color purity, red and green. The combination of yellow and yellow gives greater flexibility in the choice of color and grayscale (16.7 million colors). The luminaire is a luminous sculpture. The material form of the luminaire constructed from materials, structures, shapes and textures is also an important means of displaying art. Led technology makes the living room lamps combine scientific and artistic better, breaking the side frame of traditional lamps, surpassing the inherent concept of so-called lamp form, the design of lamps in the visual and visual artistic expression, with a A new perspective to understand, understand and express the theme of light.
Humanize
Undoubtedly, the relationship between light and people is an eternal topic. "People see the lights, I saw the light." It is this classic discourse that has changed the understanding of the lamps by countless designers. The highest level of lighting is the "shadowless lamp" is also the highest embodiment of humanized lighting. There is no trace of common lamps in the room, so that people can feel the light but can not find the light source, reflecting the humanized design that perfectly combines light and human life. .
Due to the multiple characteristics of LED, we are full of expectations for its bright future, and should not shy away from its current shortcomings.
