The "blind spot" of healthy lighting

1, the company does not pay attention to biosafety technology

With the advancement of lighting technology, compared with traditional lighting, LED lighting products have quickly won the favor of the market and consumers with their overwhelming advantages of low power consumption and long life. The government has increased investment in the LED lighting industry year after year in various places. LED companies are building a series of new lighting LED chip production lines.

Behind the development of the new lighting industry in full swing, the hidden risks of bio-safety technology of LED light sources are often ignored by people:

First of all, the characteristics of the LED light source itself make it too strong and can easily cause damage to the human eye. The LED lighting spectrum is narrow, so it has the advantages of low energy consumption and high brightness. However, relative to the full spectrum of natural light, it lacks the eye-protective properties brought by the full spectrum, and the excessively high brightness makes it lack the natural light softness and has great irritation to the eyes.

Second, narrow-spectrum light is poor in color rendering and can easily cause color weakness. Narrow-spectrum light is poor in color rendering and cannot reproduce true colors. Although light does not change visual perception in a short period of time, it is in fact "deception" to human eyes. The spectrum of the LED is not continuous, the wavelength is single, and the spectral energy of the short wavelength is very high. Under long-term irradiation of strong light of a certain band, the resolution of other colors is bound to be reduced, and the possibility of color weakness is high.

Finally, prolonged use can cause visual fatigue. The current various lamps and lanterns proposed various improvements in the light source, but did not take into account myopic objects and prolonged exposure to human eyes under non-natural light. This is closely related to the short-term disturbance of the microcirculation of the retina and the dryness of the eyes caused by blood supply disorders. Since the LED is a narrow-spectrum light, it is very different from the continuous spectrum of natural light. The LED spectrum is narrower and looks more dazzling. The spectrum of the LED is not continuous, the wavelength is single, and the spectral energy of the short wavelength is very high. Under long-term irradiation of strong light of one kind of band, the resolving power to other colors is bound to decrease, resulting in an increase in the incidence of color weakness.

2. The products on the market are uneven

In the LED is recognized as the best light source in the future, the industry has frequently exposed the problem of poor light quality LED. In theory, among the types of lamps used, LED lights have minimal harm to people's health (not just the eyes), and they can even be said to have no harm.

According to an inspection by an authoritative organization, poor-quality LED lights will produce blue radiation that is harmful to the human body, which can easily lead to vision loss, cataracts, blindness and other degrees of eye diseases. The traditional LED lamps produced by small workshops, due to the inability to control the core technologies, have a widespread problem of blue radiation. The real health LED light is not just a simple concept or slogan, but only the high-quality lighting that is produced through advanced research and development techniques and is characterized by soft light color, suitable color temperature, no radiation, no stroboscopic flash, and true color rendering. It is a health lighting.

When users purchase LED indoor lights, they can't just look at the power of the lamps because the LED lamps are not as bright as possible.

It is understood that because the higher the color temperature, the higher the luminous efficiency, the brighter the LED interior lights look. However, in actual use, the low color temperature looks more comfortable and the corresponding cost is higher. At present, in the lighting market, the power of general home LED indoor lights is between 3W and 7W, and the sales price of bulb lights around 5W is generally around 50 yuan. If it is lower than 20 yuan, then the quality of LED indoor lights is certain. There are problems, not only can not play a role in protecting vision, and the life of the light source will be greatly reduced. In addition, when consumers purchase LED interior lights, they can't just look at the power of the lamps, because the LED lamps are not as bright as possible.

3, concept abuse, certification is not complete

Table lamps are an indispensable tool for adults and children to learn and work. In order to prevent myopia, choosing a good eye protection for children has become a problem that many parents consider. According to the reporter's understanding, eye protection products on the market are dazzling, many products are advertised as "no flash" or high-tech LED lights, and the price is much higher than ordinary lamps. Can these lights not protect the child's eyes?

The reporter visited Carrefour, Guangzhou, and many other supermarkets in the lamp zone saw that half of the display lamp products were children's “eye-protection lights”. The prices of these products are uneven, the same is a table lamp, with the words "eye protection" and other words, relatively speaking, a few hundred dollars more expensive than ordinary table lamps. Some LED "eye-protection lights" are even more expensive.

The reporter observed that the desk lamp placed on the shelf did not indicate the “eye protection” function of the desk lamp. The price ranged from 80 yuan to 300 yuan. The lamp with the “eye protection” function was the cheapest to be 300 yuan. The expensive even 900 yuan. The reporter also found that in addition to the price difference, many "eye-safety" products do not have the relevant "3C" certification mark.

Some experts said that “eye protection lights” are currently more of a marketing concept. Whether or not there is an “eye protection” effect is uncertain. Consumers should pay attention to viewing security certificates and manuals during the purchase process, and it is best to choose products that have after-sales services, and Pay attention to the product's 3C certification mark.

4, insufficient attention to certification standards

Currently, the LED system under the giant monopoly of the United States, Japan, and Taiwan has a common fatal flaw, that is, there is no uniform standard for its biological safety. Although there are a series of LED photobiological safety evaluation standards in various countries, there are great differences among various standards. At the same time, it is impossible to exclude the possibility that the giants of lighting will override their own interests in the black box operation of bio-security, thus affecting the guiding significance of their objective indicators for the entire industry.

In the face of the vigorous development of the domestic LED industry, we must actively conduct research on light bio-security at the forefront of the world in order to avoid the huge strategic losses caused by neglecting the research on photobiological safety.

It is due to the absence of bio-safety testing standards for the LED industry that the government and the public are not sufficiently aware of the hazards of LEDs.
