Why can leds not be used for dimming circuits and electronic switches
Because your desk lamp is not equipped with dimmer, and the lamps and lanterns are just general lamps and lanterns rather than applicable LED light lamps and lanterns, cannot be adjusted to light.
The brightness range from 100% to 50% (the Toshiba says they can do 0-100%, I doubt). With these two methods, you can make the leds 15-100% dimming. But special lighting fixtures and corresponding dimmers must be chosen.
There are two ways to adjust the light, one of which is to be destroyed by the control points of each other, so that the overall brightness can be adjusted. But they are not evenly distributed, and the dimmers are expensive. Recently, many lighting companies in Japan have successfully developed a sophisticated dimmer, which can be tuned for multiple elements simultaneously
The incandescent lamp is tuned by adjusting the current size of the current. The lighting principle of an LED LED by a ballast changing the frequency of the ballast and changing the voltage to change the voltage will presumably be known. Dc current can only make it bright and not bright.
