First, the lights should be frequency-free flashing. The power supply frequency of ordinary fluorescent lamps is roughly 50 Hz, and this means that it is 100 bright and dark per second when it emits light, so it is a low-frequency stroboscopic flash, and at the same time, it will also make the adjustment organs of the eyes in a state of intense adjustment, which will easily lead to vision. fatigue. If the frequency of light emission can be increased to a high frequency of hundreds or tens of thousands of hertz, then the human eye will not have the feeling of stroboscopic; however, the real flicker-free is DC power supply or semiconductor solid-state light-emitting devices (such as LED light-emitting devices). The light emitted by LEDs) is also called stroboscopic flash, so consumers must pay special attention to this when purchasing LED panel lights.
Second, there is no ultraviolet and infrared light in the spectral composition of LED panel lights. Excessive exposure to ultraviolet rays for a long time will not only easily cause keratitis, but also cause damage to the lens, retina, choroid, etc. Infrared rays are also easily absorbed by water, and too much infrared rays will be absorbed in large amounts when they are gathered by the human eye lens. Over time, the lens will degenerate and cause cataracts.
Third, the color temperature of LED panel lamps must be close to natural light. Because people live under natural light for a long time, the human eye is very adaptable to natural light and has good visual effects. Because there are many color temperatures of LED panel lights, including positive white light, cool white light, warm light, etc., consumers must pay attention to choosing a light color temperature that is suitable for them and looks the most comfortable when purchasing, so that they will not be correct. Eye damage.
