Precautions for the use of led lights
1, Don`t stare directly
The light intensity of the led lamp is relatively high, it will sting the eyes, so don't stare directly at the lamp. led used for is good choice, but due to the high light intensity, it is not suitable for direct irradiation of the eyes. Because led lamp color rendering index is higher than traditional lamps, used to do is good, and energy saving, long service life, it is recommended to buy the led lamp of grinding yarn.
2、Use
More types of led lights, generally used for decoration, in home use is not recommended to be used for reading. led lights are most common is the blue light chip with yellow phosphor, this kind of light in the blue light is too much, used to read if it is harmful to the eyes. Although advanced led lights have red, green, blue light, color rendering index is more than 80, but still not recommended for reading.
3, From the point of view
The led light is a direct current light-emitting device, with our previous generations of light source issued by the light is not the same, the traditional light source including, incandescent lamps, etc. are AC, will follow the frequency of the input current of the civilian power grid changes, so the frequency fluctuation of the AC will make the traditional light source will be strobe, long-term work and study under this light source will be harmful to the eyes. But not all led are not stroboscopic, so be sure to choose is the face of the light-emitting.
4, From the optical point of view
Traditional light source will emit red wavelength light waves, this wavelength in the 780nm radiation will cause damage to the eyes, most of the myopia is long-term indoor, excessive reliance on traditional lighting under the irradiation of work and study caused by. The led light source is mainly blue light stamen excitation yellow phosphor, light emitting wavelength between 380-780nm, no ultraviolet and infrared, good led light source color rendering index is greater than 85, with a relatively full spectrum, at least will not aggravate myopia.
5, Brand
A good quality led light can minimize the harm to the eyes, so we suggest that consumers in the conditions allow, try to pick the brand reputation of the led light.
