LED product performance is not up to quality standards to be further improved

Introduction: national semiconductor lighting application system engineering and technology research center, Li Shuzhi, through the comparison of the data over the past few years, indicating that the more uniform distribution of light is better, the more comfortable the visual experience.

The optical will appear in the early stage of LED road lighting application measure of illumination uniformity is close to 1 as possible, on the other hand, the smaller the more increase of visual fatigue, and the current market for the use of LED efficiency, luminous flux, color temperature and color and other related optical index makes a simple overview.

Early application of outdoor lighting effect is not very ideal, often appear problems related to depreciation, blind, partial color, light flicker, etc.. The lightning strike is a big difficulty to be faced with LED, the main reason is the power supply is not enough. On the other hand, the outdoor lighting products in the miniaturization of modular or light source, the overall performance of the water has been greatly improved.

Li Shuzhi believes that the current industry market is not very perfect, there are many needs to be improved, but he still looks forward to the future of outdoor lighting.
