From three aspects to the selection of high-quality LED lamps
In order to let everyone satisfied to choose products, today SURE lighting will teach you from three aspects to choose the best LED lamps.
First, if there is no light in the light. The frequency of power supply common fluorescent lamp is approximately 50 Hz, and the said light brightness 100 times per second, so is the low frequency frequency flash, also can let the human organ regulation in regulation of tension, which easily lead to visual fatigue. If the light frequency to increase to hundreds, tens of thousands of Hertz above the high frequency, so the eye will not flash feeling; but it really is no flash or DC power semiconductor device (such as the LED light emitting diode) light is also known as no flash, so consumers in the purchase of the LED lamp, we must pay special attention to this point.
Second, LED lamp according to the spectral component is no UV and infrared light. Because too much to accept the ultraviolet, not only is very easy to cause keratitis, but also on the lens, retina, choroid and other damage caused by. And the infrared is also very easy to be absorbed by water, and too much infrared will be gathered by the eye lens, that is, a large amount of absorption, a long time a crystal like experience of degeneration, leading to cataract.
Third, LED lamp color temperature must be close to the natural light. Because people live in the natural light for a long time, the human eye has strong adaptability to natural light, and the visual effect is good. Because the LED light color, there are white, Leng Baiguang, warm light and so on, consumers in the purchase, we must pay attention to the choice of a the most light color, looks comfortable, and will not cause harm to the eyes.
