What is a "flicker-free" eye protection desk lamp?
"No stroboscopic" is the minimum eye protection condition for eye protection desk lamps. LED eye protection desk lamps sold on the market generally have stroboscopic phenomenon, but most consumers do not notice it.
Generally, we should consider it from the perspective of consumers. When we buy eye protection desk lamps, we try to buy desk lamps with yellowish white light, and do not buy desk lamps with blue and white light. Due to scientific verification, blue-white light has certain damage to the human eye, commonly known as blue light hazard, and long-term use will cause damage to the eyes, while the light yellow-white light is suitable for reading and writing lighting.
How to detect the color rendering of eye protection desk lamp?
Color rendering is an important requirement for eye protection lamps. If the color rendering of the light is poor, it is difficult to restore the original color of the illuminated object. The easiest way to check the color rendering of the eye protection table lamp is: use the blood red of the palm to check the color rendering of the lamp. Under the light, the blood red color of the palm is better. If there is no blood, the color rendering is not good. Color pictures can also be used for comparison.
About the environmental requirements of eye protection table lamps
The power of the eye protection table lamp is between 9W and 18W, which can meet the desktop illumination requirements of reading and writing lighting. The light power should also be matched with the brightness and darkness of the surrounding environment, and the brightness of the light and the environment should not be too different. In the case of low ambient brightness.
Finally, let's talk about the precautions for the purchase of eye protection table lamps
The first step must be to look at the national 3C compulsory certification. Avoid buying LED eye protection desk lamps from small workshops;
The second step is to look at the color temperature of the eye-protecting table lamp. If the color temperature is too high, the light will be pale and visually dazzling; if the color temperature is too low, the light will turn yellow and the eyes will be easily tired; the most suitable color temperature is about 5000K, and the light is biased Pale yellow.
The third step is to check the brightness of the eye-protecting desk lamp. Too bright or too dark brightness will cause the eyes to be easily fatigued, so the appropriate brightness is very necessary (it is recommended to choose a desk lamp with stepless dimming).
The last step is to take care of the optical processing of the eye protection desk lamp. Since the eye protection desk lamp uses LED chips as the light source and belongs to the point light source, reasonable optical processing technology is very necessary.
