Since the LED is a point light source, if it is used improperly or the light distribution is unqualified, the harm to the user will be very large. With the increasing use of indoor and outdoor high-power semiconductor lighting products, the "12th Five-Year" semiconductor lighting special plan also plans to deploy high-power semiconductor lighting products optical radiation safety research projects, mainly for semiconductor lighting products and semiconductor lighting The research on optical radiation characteristics, the establishment of hazard limits and hazard classification, and the development of optical radiation hazard detection methods and testing equipment for semiconductor lighting products with independent intellectual property rights.
"The safety and health of LED light sources is urgent and significant, which is not only related to the application feasibility and market acceptance of LED as a new light source, but also opens another brand new sky for LED applications--to health care These broader areas of application extend the commercial space and opportunities, which is interesting and instructive," said one business community representative. This is also the purpose of this salon event. On the one hand, it conducts a wide range of opinions on national issues, and on the other hand, it guides the development of LED innovation applications.
Reasonable design and use will extend LEDs from safe to healthy applications
Some people surveyed more than 30 volunteers and received a 30-day lighting experiment. The lamps used LED light source and the color temperature was 2800K. The experiment found that the volunteer skin did not change. Therefore, the experimental results prove that LED lighting is safe for the skin. At the same time, the fluorescent lamp contrast experiment was carried out. The results showed that the fluorescent lamp illumination was harmful to the skin, the color of the skin changed, the L value decreased, the M decreased, the A value increased, and the E value increased. The color of the skin turns red and the water content of the skin also tends to decrease.
Outdoor Fixed Led Display is perfect for commercial advertising, stadium, government public announcement etc. It takes the advantage on brightness, seamless, color consistency pixel to pixel, energy saving, long life span etc. Also, it is more environmental, It could change content to play everyday by software instead of changing the printing or plastic materials when you needs to change the advertising banners.
