Under the background of low-carbon economy, energy conservation and environmental protection, the Chinese government vigorously promotes the development of LED energy-saving lighting industry. The promotion of national policies and the trend of market laws make the development prospect of LED lighting industry promising. Driven by huge potential benefits, many enterprises have formulated industrial development policies to promote the rapid growth of LED lighting industry. Recently, Guo Wenjun, director and chief engineer of the lighting planning office of the Urban Planning Institute of China Urban Construction Research Institute, expressed some of his views and views on the development of the increasingly hot LED lighting industry in recent years.

Improve people's lives with meaningful lighting innovation

In my opinion, this topic has always been and is being done. Different environments need different lighting environments, but the same purpose is comfort and health. This topic might as well be changed to "improve the combination of technology and lighting to improve people's quality of life". The progress of lighting has been innovating for more than 100 years, but at this stage, more technologies and methods have been applied to life. In the 1980s, there will be no embodiment of intelligent control of lighting. Don't be limited to lighting here. More ways will be combined with lighting to improve synchronously. For example, the combination of intelligent control system, stage lighting, computer software system and intelligent control lighting can control light and color in mobile phones. These are not just lighting innovation. Many manufacturers have introduced to me recently that their products can be tinted at a temperature ranging from 2800k-5000k, while I have long seen light source modules that can be tinted at a temperature ranging from 1700k-4500k, which can bring people a transformation from the light environment of enjoying candlelight dinner to the modern office environment. Isn't this lighting to improve people's quality of life?

LED lighting has replaced traditional lighting?

There has always been no conflict between traditional lighting and LED lighting. In fact, this statement does not exist in the United States, Germany, Japan and other countries I visited, because the means of artificial intelligence lighting is always to improve people's living water products and enjoy the comfort brought by artificial intelligence lighting when there is no natural light or dark clouds. LED is only known as the fourth generation light source. As a high-tech, like PC, it exists to improve people's quality of life, and what we lighting practitioners need is how to apply it scientifically and reasonably. Therefore, there is no substitute. Incandescent lamps have been invented for so many years, and we are not using them. In the future, incandescent lamps and halogen lamps will be used in some places in the market. We don't have to always think about substitution, and science is progressing and developing step by step.

About the technical problems of LED lighting that we are more concerned about

The package of cob light source is more like an "area like light source" than the light source lamp encapsulated by single crystal. It can better facilitate secondary or tertiary optical design without tangled overall lamp efficiency. What is more important is how much useful light shines on the illuminated object. The shadow forming cob light source of the object is clearer than that of single crystal packaged or combined lamps, and the light spot is free of noise and shadow.

The lens can control glare better than the reflective cup. Don't let excess light direct into human eyes, which will bring problems to people's health. There are suitable means to control the light loss rate.

The improvement and improvement of light source packaging process and materials can improve the reduction of light source area, reduction of thermal resistance, smaller color tolerance, elimination of color drift and so on. So as to change the heat dissipation mode and volume of lamps. To cure the disease, there will be no problems such as lobby lighting, high pole lighting, what can not replace halogen lamps of more than 70W to 300W (to modify the original lamp hole size specification), etc. In this way, the overall lighting problem of T3 terminal of capital airport can be solved.

Don't always ask questions based on surface phenomena without proposing solutions, such as "blue light hazard", color fading, color drift and other problems. Quantum dot illumination technology and phosphor process control can effectively solve these light source problems.
