Hua Shuming: LED development should focus on the basic theoretical research of light

Humans have lived in the sun and the light for hundreds of years, and only lived under artificial light for nearly 100 years. Light has a very close relationship with people, and production and life are inseparable from it. Semiconductor lighting has made the light more diverse. In the past, the color and form that fluorescent lamps and traditional lighting could not achieve can be realized. This has opened up a broad and unknown field for lighting. It is worth studying and predicting its future technological development. This will make it possible to grasp the future.

What kind of light do people need? What kind of light is good for people? Now everyone's attention is on light efficiency. Energy conservation is the first priority. After energy saving, people should feel comfortable and improve people's living environment. However, at present we have too little research on light and people, so we should strengthen the study of people and light, especially the issue of people and semiconductor lighting.

The emergence of semiconductor lighting will modify our traditional lighting concepts in some places, and will also modify the basic theories of photometry and colorimetry in some places. Basic theoretical research is currently done by Europeans and Americans. We should also use the era of revolutionary changes in lighting to catch up and strengthen the basic theoretical research of lighting-related technologies. Based on the previous photometric and colorimetric foundations of natural light, sunlight, high-pressure mercury lamps, fluorescent lamps, incandescent lamps, etc., and based on the spectral characteristics of LEDs, and breakthroughs in two or three years.

At the same time, semiconductor lighting, like other industrial technologies, should be the first test method, and the product performance index is later. Chinese people should study their own test methods. The standards for semiconductor lighting are not the most advanced. Performance standards should not be rushed, giving people an imaginative upside. The most important of the semiconductor lighting product standards is the standardization of the product specifications, and the uniform specifications should be determined first. It is difficult for China to determine specifications based solely on corporate strength. It should rely on government power, rely on industry and alliances, and rely on every semiconductor lighting industry worker to work together.

It is recommended to study the basic theory, apply the basic theory of photometry, colorimetry, the basic theory between man and light; study the standardization of product specifications; study the unification of test methods, test methods should not be blindly from abroad, should be actively carried out abroad Cooperation, to influence them, this is our strategy.
