How much LED color temperature is good for the eyes?

Color temperature is the most general indicator of the spectral quality of a light source. Generally expressed by Tc. Color temperature is defined by absolute black body. Nowadays, LED lamps and lanterns are very common in life. There are various colors, so how much LED color temperature is good for the eyes? Next, Yijingyuan Broadcasting & TV will come to explain it for you. A report pointed out that white cold light LED and blue light LED are harmful to the eyes and should be banned. These LEDs are mainly used for decoration, and the intensity of blue light emitted by them far exceeds that of natural lighting and traditional lighting. These high-intensity blue light will cause damage to the pigment epithelium of the retina and the sensory layer of the retina at the same time, thereby accelerating retinal aging and increasing the risk of macular degeneration. The biggest victims of LEDs are children under 10 years of age. Children of this age have neither cloudy lenses nor macular pigment, so they lack the ability to resist blue light.
The LED lamp uses a blue chip and an external yellow phosphor to be mixed to produce white light, which makes the content of blue light in the LED lamp relatively high. Blue light refers to the blue light band of 400-500 nanometers. If the brightness is too high, the eyes may cause photochemical damage to the retina after looking directly at the light source for a long time. The degree of blue light hazard depends on the accumulated blue light dose received by human eyes under the light. According to national regulations, the color temperature of LED lighting cannot be greater than 4000K. However, due to the high light efficiency and relatively low cost of high color temperature LED light sources, there are many high color temperature products on the market.
Color temperature is the most common indicator of light source spectral quality. "Warm light" has a low color temperature, while "cold light" has a relatively high color temperature. After the color temperature increases, the proportion of blue radiation increases, and the blue light increases accordingly. At the same time, brightness also affects the proportion of blue light. Generally speaking, fluorescent lamps and LED lamps with the same color temperature are basically harmless as long as the brightness of the latter is not more than 3 times that of the former. However, for individual LED lamps that are too bright, the proportion of blue light may exceed the safe value. As the LED technology matures, manufacturers no longer need to blindly increase the color temperature and power of lamps to achieve high lumens, and objectively reduces the possibility of excessive blue light.
