LED in the blue eye damage?

On national quality supervision and inspection center of the lamp to Taiwan to take part in the twentieth cross strait lighting technology and marketing seminar, not only in the blue light hazard LED products, metal halide lamp and fluorescent lamp used in the past have some doubts and blue light hazard, blue is heavy to form white light spectrum, no blue without white, use with the product quality and safety is closely related to the degree of.

LED blue eye damage to the eyes in recent years has become a global concern. With the application of LED lighting is more and more widely, for the consumer's attention issues of blue light hazard also continues to heat up, in order to clarify the consumer adoption of LED lighting products doubts, mentioned LED blue light hazards report of national quality supervision and inspection center of lamps, LED package components of single power of 1W products must strengthen the structure of protective measures, and indoor LED lighting products color temperature should not exceed 4000K. On national quality supervision and inspection center of the lamp to Taiwan to take part in the twentieth cross strait lighting technology and marketing seminar, not only in the blue light hazard LED products, metal halide lamp and fluorescent lamp used in the past have some doubts and blue light hazard, blue is heavy to form white light spectrum, no blue without white, use with the product quality and safety is closely related to the degree of.

LED in the blue eye damage

Blue and blue rich definition of harm and influence is not the same as the blue light hazard vs rich blue LED lighting products caused by blue light hazard argument was caused by the "blue" color, smell the market what is the blue light hazards, national quality supervision and inspection center of lamps is also proposed the definition of blue light hazards, "when the blue radiance to meet the standards of the 2 class 3 or class, will be in a relatively short period of time or moment to harm human eyes" is the blue light hazard. Among them, 2 types and 3 kinds of standards were in danger (2), the radiance is less than 4 * 106W? M-2? SR-1, the light does not produce of high light and temperature does not reflect the harm; high risk (3), radiance >4 * 106W? M-2? SR-1, the light in a shorter moment harm.

National Quality Supervision and inspection center of lamps also explain differences between densely exposed to blue light wave radiation of the "rich blue" and "blue hazards, rich blue physiological effects" of the lighting on people is silent and be after months or even years, will significantly affect the person's biological clock. But there is no corresponding assessment criteria.

How far away from the influence of the harm and the rich blue blue lamps according to the national quality supervision and inspection center survey, in the sample, there are 1 products in the use of 2 kinds of abnormal issued to blue risk criterion, this product uses LED single module power up to 1W, the LED package per unit area of the light output of a large amount of at this time if the eyes open source in this category, it may make the blue light hazard situation, therefore, take the LED package this kind of power should be taken as diffusion cover and other necessary structural protective measures, warning signs and notes.

In addition, a major factor in the quality of blue chip coated fluorescent powder is whether to affect the health of the blue light, the survey shows that many LED fluorescent powder mix unknown source or origin and coating quality is poor, resulting in very high temperature, such as the color temperature is far more than 6500K, even to 100000K and other products, this type of product the long-term use of biological clock on the human impact is the effect of rich blue, fear will affect sleep, caused by the biological clock disorder, and lead to lower immunity. Therefore, the national quality supervision and inspection center of lamps also suggested that in order to avoid the use of high temperature rich blue LED lighting products on the human health effects caused by fear, LED indoor lighting products using the color should not be more than 4000K products, color rendering index should be more than 80.
