Change the dimmer switch, a few dollars, you can generally repair it in the place where the table lamp is sold, but the maintenance cost is high.
Do not take it.
The dimming principle of incandescent lamps is very simple, that is, a variable resistance (knob to adjust the size of the resistance) The principle of energy-saving lamps is electrode discharge. The dimming condition is to control the ionization of the gas in the lamp, and the adjustment is to control the discharge frequency and wax sensitivity (adjustable ballast). >>>More
It may be that the bulb is unscrewed when the lamp is the brightest, and then screwed to the dimmable lamp after the other lamp head is tried, and then the full voltage is added to the cool bulb, and the impulse current is a little larger, and the lA bidirectional silicon breakdown is short-circuited. , change to a bidirectional thyristor.
Do you have a junior high school physics book at home or with friends? I remember learning about electrical circuits when I was learning (like a lamp in a hallway, can you turn it off when you turn it on downstairs). The diagram is as follows..../ …… >>>More
Poor contact leads to an increase in resistance, and the current is converted into heat energy when it passes, so it is recommended to replace the switch, which will have a fire hazard.
There should be none, the remote control switch of the electric light only receives, does not emit.
