Many people heard after the
battery powered beacon lights Blu ray injuries all doubt and anxiety, experts said, LED lights with no problem in the outdoors and large sites, but the family should be used with caution, especially the three kinds of people need to be careful.
Although the
led blue beacon light ray injury problems, the industry and experts are not completely consistent. But there is no controversy one point, that is LED light, belonging to the rich blue. Member, international optical radiation safety standardization committee professor Mou Tongsheng reminded, there are three types of people should be used with caution, first class, all want to get, is a delicate children eyes. The other two kinds of people, generally know very little:
Diabetes after ten years of development, has the retinal lesions, retinal light damage under about value decreased significantly, and drugs, we live in a lot of drugs are photosensitive, after we have eaten medicine, light damage may be more obvious.
Reporters learned that medical experts, photosensitive drugs are not under twenty, including doxycycline, ciprofloxacin, oral hypoglycemic agents are commonly used in D-860. Patients taking these drugs, not only with the lamp to be careful, the sun also need to be careful.
In the discussion, and a term was frequently mentioned, that is "color temperature":
LED energy-saving, but do not do very high color temperature. (indoor, color temperature to drop down. )
The so-called color temperature, color of light source is a measure of the scale, warm light of low color temperature is what we usually say more components, red, blue is less. On the other hand, cool shade of blue, the color temperature is high. Our common light source, the temperature is about 2000K, incandescent lamps are 3000K, the morning sun at noon about 4400K, up to 5600K. Senior engineer, Shanghai Lighting Association chairman Yu Anqi said, people with different times of the day, conform to the laws of nature is the most ideal, but now on the market of the LED lamp, the color temperature is higher, the interference to the human body biological clock:
When the household lamp is mostly in the evening, low color temperature of light, the measurement of 27 product color, there are seven samples is much higher than that of 6500K, and even more than 100000 K, has exceeded the upper limit of white color temperature lighting products, long-term use, will affect sleep, as a biological clock, thereby reducing the people immunity.
This point, consumers know too little! A reporter through a dozen lamps, outer packing are not Biao Mingguang as the color temperature. There are two only in the manual. Expert appeal, countries should set, lighting products on the packaging to make color much scale. Professor China chairman
car beacon lights Forum Zhang Haicong said, consumers should avoid a mistake, is light to shine better more. The best LED lamp with lampshade, on the one hand, the light can be more soft, on the other hand, inspection certificate, such doing can put the blue spill is reduced by 1 to 2 orders of magnitude:
In order to improve the light efficiency, many manufacturers use unscrupulous divisive tactics, the most obvious is the lamp, a lot is a bare, the person is uncomfortable. Table below are cover, put into a sting eye does not sting the eyes.
