Can't you use energy-saving bulbs or LED screw bulbs on the lamp holder of dimming desk lamp?

The dimming principle of dimming desk lamp is to use thyristor (SCR) to adjust the conduction angle and change the power-on time of alternating current to power the bulb, so as to change the average value of power supply voltage and current and adjust the brightness of the lamp.

Energy-saving lamps and LED lamps have power conversion, and both need to convert the alternating current of the power supply into direct current, and then convert it into high-frequency alternating current (energy-saving lamps) or direct current constant current (LED lamps) to drive the light-emitting part.

When the dimming is adjusted to the maximum position, there is little difference between the power supply after the dimming switch and the direct AC connection, and the energy-saving lamp or LED lamp can be lit normally.

Working in this state will not have a bad influence on the lamp.

Only the dimming function is wasted.

If the dimming is turned to the middle position, the energy-saving lamps and LED lamps will not work normally because of the weakened power supply.

For energy-saving lamps, it will flicker, which will affect the life of energy-saving lamps.

For LED lamps, it will cause low brightness and instability, but it will not affect the life of LED lamps.
