At present, the light sources used in writing desk lamps on the market are mainly incandescent lamps, quartz halogen lamps and eye protection lamps. Incandescent lamps mostly use bulbs with power consumption of 40W-60W as light sources, do not need ballasts, and are cheap. The price difference is mainly reflected in the process of modeling lamp shells. On the low side, the life of the bulb is short, and the bulb is a spherical point light source, which makes it difficult to form a large and uniform high-illuminance area. Therefore, in developed countries abroad, it is no longer used as a lighting for writing, but only as a craft decorative lamp.

Avoid stroboscopic
Writing desk lamp If it is dedicated to the readers, in addition to the brightness, it is necessary to avoid stroboscopic. The AC light source used in daily life often has the phenomenon of light and dark replacement due to the constant change of voltage. This light flash phenomenon is called stroboscopic. The flicker is less than 100 times per second, which is a low frequency flicker, which has strong irritation and damage to human eyes. Reading and working under this light source for a long time will cause young people to have dry eyes, eye pain and eye fatigue. It is easy to cause myopia.
At present, there is a flicker-free vision care desk lamp on the market, which converts ordinary AC signals into high-frequency signals through electronic processing, so that people’s eyes cannot feel the stroboscopic phenomenon, which is very beneficial to protect eyesight .
