[Hui Cong Lighting Network] In the 1950s, incandescent lamps and fluorescent lamps were the only two sources of light, which were widely used in various places. In the late 1950s, the successful development of high-pressure mercury lamps took a step in the innovation of new light sources. Since then, many industrial plants and urban road lighting have changed to high-pressure mercury lamps, playing a huge role; in the 1970s, China began to appear high-pressure sodium lamps, which were gradually applied to road lighting; in the 1980s, compact fluorescent lamps and thin-tube fluorescent lamps Appeared, and further improved the energy saving space. Later, the emergence of rare earth trichromatic fluorescent lamps once again promoted the advancement of high-quality and high-efficiency light sources. The successful application of electronic ballasts to fluorescent lamps can be regarded as another energy-saving revolution. The white light semiconductor light-emitting diodes (LEDs) that emerged in the 1990s and the rapid development of more than a decade have given the world a new imagination for new energy-efficient light sources. Therefore, these major advances have pushed the development of the light source business to a higher level.
LED lighting, as a new type of light source in the 21st century, has developed rapidly in recent years and is also an innovation and revolution in the history of light source. It is destined to occupy an important position in the future. However, the real problem is that the hype of LED lighting is a bit overheated, and there are still a series of problems to be solved in LED lighting. How do we view the growth of LED lighting objectively and rationally? I believe that we should look at the development of LED lighting with a development perspective, optimistic about its future prospects, adopt a positive and enthusiastic attitude, support and promote its development, and in application. Improve, improve, but should not be blindly and disorderly promoted. Just as a child learns to walk and wrestle when he is one year old, his growth requires a process, and it is unrealistic to talk about large-scale applications now. If the society can't treat LED lighting correctly, there will be two problems: one is too big investment, the investment is wasted; the other is that there are more hidden dangers for the future.
I am not conservative or an opposition to whether or not to support the application of LEDs in lighting. However, what I oppose is the kind of exaggeration and bragging about the fact that regardless of the actual situation, regardless of the object, and not actively solving the problems in the advancement, blindly pursuing the number of pushes and unrealistic indicators, claiming energy saving of 60% and 80%. way of doing. Therefore, I hope to start from the analysis and find a place suitable for my own characteristics, pilot first, and gradually promote. For example, indoor lighting should first be used in residential stairwells, walkways, etc., which need to be equipped with energy-saving self-extinguishing control switches. This is a "small project" that is suitable for LED advantages and has great economic and social benefits. Another example is the shop window, the product display rack, the key lighting of the cabinet, as well as the lighting of the auxiliary spot such as ceiling spotlights, wall washers and corridors, bedside lamps of the hotel, night lights, etc.
LED road lighting should also be analyzed. Low-power (such as 150W or less) LED street lights have certain energy-saving effects. The sidewalks, branch roads, residential roads, and pedestrian streets can be applied gradually, and the scope is gradually summarized, improved, and expanded. In short, the initial stage should start with “small thingsâ€, not greedy, often starting from “small placesâ€, more effective, less detours, and easier to succeed.
Following the path of conformity with objective laws, I believe that after several years of development, LED will gradually become a new type of light source with excellent performance, more energy saving and environmental protection. The lighting field will usher in a new era.

Personal profile
For more than 40 years, he has participated in or presided over the electrical design work of many projects in China's aviation industry, and made his own contribution. From 1981 to 1984, he was specially appointed by the Ministry of Foreign Trade and Economic Cooperation to Hong Kong to serve as the 53rd-level director of electrical engineering of China Resources Building. The design of the building plan has made outstanding achievements. Over the years, we have done some research in the fields of low-voltage power distribution and lighting technology, and have a deeper understanding. We have provided a large number of technical consultations for China's building electrical designers and enterprise technicians, and have done a lot of work.
Over the years, he has hosted or participated in the compilation of 11 national, industry and local standards, such as “Architectural Lighting Design Standards†and “Emergency Light Safety Technical Requirementsâ€; edited “Cigarette Lighting Design Standards†and “Green Lighting Engineering Technologyâ€. Procedures, etc. Host or participate in the design of eight manuals, such as the editor of the "Industrial and Civil Power Distribution Design Manual", "Emergency Lighting Design Guide" and so on.
In the past 10 years, more than 30 research results and technical articles have been written. For example, China's "Energy Saving Forecast for the Next Ten Years" prepared in 1990 has been selected into the 1991 National Energy Conservation Week Proceedings, which provides a reference for China's green lighting engineering plan; "Selection of Protection and Protection of Low-Voltage Distribution Lines" has played an active role in propaganda, explanation and implementation of gb50054-95; "Enhanced Energy Saving in All-round" was selected as a technical publication of Hong Kong cie 1996. Quasi-review and product identification, such as "Low-voltage electrical basic technology", "Low-voltage circuit breaker", "Low-voltage fuse", "Low-voltage power distribution design specification", "Lighting design standard", "Fluorescent energy efficiency limit value and energy-saving evaluation value" And other national standards; participated in or hosted circuit breakers, intelligent sets of cabinets, intelligent trip units, DC fluorescent lamps, electronic ballasts, fire-resistant cables and other dozens of department-level identification work.
Personal honor
In the 1970s, he cooperated with the Institute of Physics of China Academy of Building Research, organized and hosted the system testing and research work of China's luminaires, and compiled a total of 3 volumes of "Common Lighting Lighting Design Calculation Charts", which is the foundation of China's first independent completion. And practical research topics, won the 1978 National Science Conference Award.
Executive director of China Lighting Society, director of the indoor lighting professional committee of the society, deputy director of the National Lighting Standards Technical Committee, member of the China Association for Science and Technology Engineering Energy Conservation Committee.
