Rumors: LED lamp Blu ray really hurt the eyes?

Incandescent lamp, LED lamp. There are a variety of LED lamp "harm" argument, from time to time in the network, the circle of friends thrown up: damage to the retina, great impact on the eyes...... Really?

Do you have such an article of the circle of friends - LED Blu ray will damage the retina, LED Blu ray has a great impact on the eyes, uncover the secrets behind the LED Blu ray"...... To have eliminated the incandescent lamp, home all installed on the LED source of consumers, look at these undoubtedly have a little Meng ring.

If the blue light of LED lamp is harmful to the eye, can you still use? With the popularity of LED light source, a similar topic must be authoritative interpretation.

According to statistics, the global LED lighting market size increased from about $5 billion in 2011 to about $20 billion 400 million in 2015, an average annual compound growth rate of over 40%. With the enhancement of environmental awareness of the global energy crisis intensifies, residents and LED lighting technology progress and cost reduction, is expected in the next few years LED lighting industry will maintain a rapid growth rate, to 2020, the global LED lighting market will exceed $70 billion, 2015 to 2020 compound annual growth rate of nearly 30%.

With the elimination of incandescent lamps in October last year, China plans to enter the final deadline, LED light source is also becoming the mainstream market products. February 9th, in the vicinity of the city of Shili River, Beijing lighting, LED light source to become the absolute mainstream, and even some students learn to use the light on the product packaging directly on the "no blue" words. "Why do you write 'no Blu ray'? Is blue eye harmful to the eye? "In the face of questions from reporters, the store quickly explained:" it is said that the LED blue light is harmful to the eyes, but in fact, as long as a qualified product, radiation brightness blue are in a reasonable range, there is not much harm to the eyes. Most consumers passive choice

Although the LED blue light is harmful to the eyes "speech has been spread on the Internet, but for most non professional consumers, even if some products are harmful, do not know how to choose to buy qualified products. So I do not dare to buy too cheap, the choice is also a big brand. Consumers Chen Xiaomin told reporters. The spectrum of light flux is such a professional vocabulary is so that consumers can not touch the mind.

So, is it possible to see through the product parameters to see the blue light content? Shop staff told reporters that only from the product release voltage and frequency is unable to calculate whether the excessive blue light, because the voltage and frequency is the electrical indicators, while the blue light is an optical indicator. And it claims that the luminous flux is an optical indicator, but only the total luminous flux of white light, rather than the blue light flux, so it is difficult for consumers to determine whether this is a blue light excessive. The majority of consumers, or directly say what brand, what specifications, directly away. Really 'truer' really not much. Staff told reporters. Indoor LED light source color temperature does not exceed 4000K

So, LED Blu ray in the end how much harm? In fact, the blue light hazards and the rich blue lighting is not the only LED lighting products, before some of the metal halide lamp and some fluorescent lamps already exist.

China Lighting Association vice chairman of Science Committee An Lanpo told reporters, to distinguish between blue light hazards and "rich blue" lighting effect people's secretary Chen rhythm in these two different situations, Blu ray harm is when the blue radiance reached the standard requirements of the 2 class or 3 class, in a relatively short period of time or moment to harm human eyes, it is based on the standard GB/T20145-2006/CIES009/E:2002, the decision is based on the CTL-0744_2009-laser resolution. The physiological effect of rich blue "lighting of the people is silent and after several months or even years time will significantly affect the division Chen rhythm, which is a popular topic in the world of scientific research, research more, but there is no corresponding assessment criteria.

Under normal circumstances, the room can only use blue light hazard classification in 1 categories and below LED lighting products. In order to avoid the possible adverse effects on the human health due to the use of high color temperature rich blue LED lighting products, indoor LED lighting products should not exceed 4000K color temperature, the general color rendering index should be more than 80. Indoor lighting should avoid the use of color temperature 5000K and above LED lighting products. Ann Lanpo also said that blue is an important part of composition of white light, so under normal circumstances to filter out the blue light is one-sided, according to our choice of human physiological rhythm Chen light component and quality, it is right.

For a particular group of people (who are affected by diabetes and photosensitive drugs), or may be in a particular position (such as infants and young children) can look directly at the LED lights, should be used without harm LED lighting products.

Because the infant eyes delicate, unable to filter on Blu ray, and patients with diabetes after years of development, have retinopathy, retinal light damage bears about value decreased greatly, the effect of blue light on the larger vision.
