LED to promote fine lighting intelligent lighting presents three characteristics

Since the beginning of the last century in 90s, LED as the fourth generation light source into the public view, and a huge impact on traditional lighting.

Liang Rongqing, director of the Institute of electric light sources, Fudan University, said that due to the inherent characteristics of technology, the emergence of LED lighting industry is going through a very important period. In the past, the light source is a relatively closed concept, basically consists of the bulb and the light distribution device and a set of power supply system, and the connotation of modern light source is more open, it can be different and cross industry integration, intelligent, personalized lighting. New light source technology innovation, so that the lighting into a new era, and then to the cultural and economic and social development have a significant impact.

LED promotes fine lighting

Traditional lighting is a basic lighting, once the light source is fixed, the light is constant. The intelligent lighting is an extension of the basic lighting, it can be adjusted by changing the parameters of light. If the previous lighting is extensive, it has now entered the era of fine lighting.

Liang Rongqing believes that digital is the basis of intelligent lighting, which includes two aspects: first, the excavation of digital communication technology, the two is the technical characteristics of LED itself. Among them, the characteristics of LED easy to control fully meet the requirements of intelligent lighting. LED wide range of adjustment, can be adjusted continuously, rapid response, the upstream industry chain enterprises can make different spectral chips, later re deployment of more colorful light.

In fact, in the 80s of last century, there are experts on the gas discharge lamp intelligent control, but the characteristics of the gas discharge device determines the technical difficulties in achieving control. It can be said that thanks to the characteristics of the LED light source itself, the achievements of today's brilliant intelligent lighting. However, despite the development of digital technology to make LED intelligent control become more abundant and easy, but how to make the lighting more digital, intelligent but also faces some problems.

Unlike the past extensive "intelligent lighting lighting, a lamp can be used, is a solution of intelligent lighting system, this system should be compatible with different interchangeable lighting solutions in different light conditions, there must be in the standard logic between different lighting solutions. Liang Rongqing said.

In English, intelligent lighting is known as smart lighting (smart lighting), but the situation is just the opposite, because the smart lighting is very complex, the need for human control. In Liang Rongqing view, the real intelligent lighting is not too much interference, it can be based on user needs to provide the best lighting, that is to say, intelligent lighting must be adaptive, self adjustment.

Intelligent lighting presents three characteristics

Referred to intelligent lighting, we first thought is energy saving, LED luminous efficiency of up to 200 lumens per watt, electricity saving effect is very obvious. More importantly, the intelligent lighting due to the energy saving effect of regulation also can not be ignored.

Liang Rongqing for example, in the office buildings near the window position, the light is bright, away from the window is slightly dark, with the weather conditions, different seasons, the light distribution in the building is not the same. But for employees in the building, the light is constant. Intelligent lighting can be perceived through the sensor indoor light intensity in different positions, so close to the window light brightness is relatively weak, by the side of the lamp brightness is stronger, so that the indoor lighting brightness consistency. Make full use of external natural light, intelligent lighting virtually achieved the power saving.

Lighting electricity accounts for about 12%-13% of the total electricity consumption in the whole society. Some experts estimate that if the use of intelligent lighting instead of traditional lighting, can achieve 50% saving, to reduce energy consumption, building a conservation oriented society of great significance.

Secondly, intelligent lighting can provide a healthy and comfortable lighting effect. Different light sources will have an impact on the physiology and psychology of human beings, and LED can adjust the color temperature, color rendering, intensity, distribution and other parameters.

Liang Rongqing said that the pilots of the long flight mission, in the light of different lighting, the psychological state is not the same. Now use the LED light source, can be called a "light formula", with the best lighting for the pilots of the environment, so that they always maintain the most sober state of mind, improve flight safety. In addition, LED lighting can imitate the trajectory of the sun, so that indoor lighting is almost close to natural light, so that long-term in the ship, geology and other indoor work groups to get natural light to avoid depression and other diseases.

Third, intelligent lighting and convenient management, help to improve the transportation efficiency. Liang Rongqing street lamps, for example, there are tens of millions of street lamps, and responsible for the maintenance and management of personnel is very limited. If the use of intelligent lighting, you can achieve fixed-point management, which is a real street lamp feedback to the control center, targeted maintenance, greatly enhance the efficiency of operation and maintenance management.

LED as a new generation of light source is applied to the lighting, so that the lighting presents an infinite possibility, but also to personalized lighting, custom lighting needs to become a reality. Of course, all this is due to the characteristics of LED itself.
