Can LED lights be dimmed?
Can ah. The LED lights that our company makes are adjustable.Desk lamp is adjustable light, protect eye lamp
LED lights are not normally tuned, and you can choose the number of light bulbs to adjust the brightness
You can adjust the light, as long as the chip is supported, and the power driver support can be tuned, and as far as I know, almost any big plant can be tuned.
You can. Dimming is to use the simplest potentiometer, by changing the series resistance to change the current in the circuit, so as to realize the dimmer, it the biggest harm is the power consumption big, circuit is not economic. Dimming is complicated in dedicated LED driver chip, it is by changing the external resistance to change the current size, but its efficiency is higher than the previous lot, and power consumption is small. PWM wave is actually a series of square wave, just change the duty cycle of square wave, the principle of it is by changing the current conduction time length to change of light intensity, short circuit conduction time, light is darker, brighter and vice. The effect is very good, the efficiency is very high, but the improvement is very difficult, maybe will burn out.
