Can LED blue light monitor be implemented in our country?

At the recent 2013 China International Semiconductor Lighting Application Technology Forum, a number of domestic experts called for updating China's existing light bio-safety indicators, and proposed that the country adjust the light bio-safety standards from the recommended standards to mandatory standards, and at the same time Nationwide risk monitoring of LEDs against blue light.

Recently, there is news that LED blue light spills may cause damage to the retina, and even blindness. Is the LED lamp known as the fourth generation light source insecure? “LED Blu-ray harm” caused a sensation due to the blindness caused by the Xi’an baby bath. In this forum, the experts attending the “Lighting Safety” theme went deeper. Explore. "The current standard limits are based on adult and experimental data and do not take into account certain special populations. For example, infants and young children may stare at the light source for a long time and cause damage to the retina." Eye and ENT Hospital, Fudan University Dean Sun Xinghuai pointed out that children with delicate eyes, the elderly, and consumers with eye diseases should pay attention to the dangers of blue light. This type of special population should use zero-class products.

Experts have suggested that research and establishment of semiconductor lighting standards system, gradually update the product testing standards, safety standards, performance standards and energy efficiency standards, starting from product applications, and gradually promote the industry chain.

In fact, all lighting sources, including natural light, contain a blue light component, whereas in LED light sources, the white light emitted by most light sources is formed by mixing a blue LED chip with a yellow phosphor, and the proportion of blue light energy is higher than that of the LED light source. other. By developing a product with a low color temperature, enhancing secondary light distribution can significantly reduce its hazards. The current priority is to formulate mandatory standards at the national level.

It is reported that China's identification of light bio-safety mainly refers to the "National Standard for Photobiological Safety of Lamps and Lamps", and its update rate is lagging behind, and it is not mandatory. It is difficult for companies to be binding.
