Southwest University of Science and Technology LED lighting equipment development and application project passed the appraisal

It is reported that the research and development of the Southwest University of Science and Technology, "Efficient and low-power intelligent LED lighting equipment development and application" project recently passed the expert group appraisal.

The expert group believes that the LED lighting equipment developed by the project has the characteristics of adjustable brightness, temperature automatic control and automatic power consumption adjustment. The project research methods and technical approaches are innovative and the results have reached the domestic leading level. The core technology of the project has independent intellectual property rights. After popularization and application, the market prospect is broad, which has produced significant economic and social benefits. It is also recommended to further increase the application and industrialization of the results.

According to Zhang Jiangmei, project host and associate professor of Southwest University of Science and Technology, high-efficiency and low-power intelligent LED lighting equipment controls PWM output according to LED current brightness, total power consumption, light efficiency and temperature-light efficiency curve to achieve LED brightness and light efficiency. With the best balance of temperature, it can be widely used in the field of civil energy-saving lighting.

At the same time, the project also designed a low-cost anti-flicker LED control circuit, which can greatly suppress or eliminate the flicker phenomenon of LED, meet the lighting needs of special fields, and promote the application of LED in a wider range of fields. The project also studies the use of flexible manufacturing technology to form a modular production technology for multiple series of LED products, significantly reducing the cost of a single product.
