LED table lamp power supply selection and requirements

- Nov 05, 2019-

There are many LED driving methods. In the desk lamp products, we use low voltage constant current driving. The constant current driving method is an ideal LED driving method, which can avoid the current fluctuation caused by the change of the LED forward voltage, and the constant current stabilizes the brightness of the LED.

 

Generally, the AC-driven light source has a stroboscopic effect, which causes the optic nerve to be easily fatigued by the ever-changing light intensity. The LED driven by the constant current can emit stable light without stroboscopic phenomenon, which makes the visual feeling very comfortable. The desk lamp is a safe low voltage input, which avoids the safety accident caused by circuit failure of ordinary lamps.
