Power LED Dimmer Circuit

A quality and stable LED dimmer circuit is built on LM358 and LM393 opamps, the operating frequency of BUZ71A mosfet is used in the power floor. 150Khz brightness and precise light adjustment can be made. The operating voltage of the LED dimmer circuit is between 12 volts and 24 volts, max. 1.5 amps

Dimmer for LED modules

With modern LED orders can be many light and lighting effects. Especially in bright LED configurations such as cluster or LED Stripes, is the question of the possibility of Dimmens the brightness of these orders. Our little dimmer project addresses precisely this task. The pulse width scheme , the control electronics almost . About one can Comp also an external potentiometer brightness setting to be connected, so that the operation locally separated from the actual control electronics can make.

Ddimmer for LED modules

Many light and lighting effects can be achieved with modern LED products. Especially in bright LED configurations like clusters or LED Strips, there is the possibility of dimmering the brightness of these products.

Our uninspiring little project tackles exactly this task. Pulse width diagram, control electronics almost. Approximately one component can also be connected to an external potentiometer brightness adjustment so that it can operate locally separately from the actual control electronics.

LEDs are conquering other fields of application, possibly offering numerous incandescent lighting tasks. This of course means that there is a certain Atmosphere in terms of bright light, especially in areas with low lighting. Here you can create colored light, dots, light frames, etc., with very little effort.

You can get a wonderful visual effect such as And just where a certain ambiance is to be created, modern LED arrays appear, whose high Brightness is often very bright, up to Intrusive. . So here it makes a dimmer meaning. The course is the corresponding benefits of LEDs, inter alia, to the almost cold produced Light. Thanks to linear regulators, these regulators, which do not have much power, are easily destroyed, that is, heat is produced, but possible losses.

This is achieved with pulse width control because the pulse width Modulator (PWM) is used. This results in a periodic input of the connected load with a variable rate (Pulse-0 to 100 %) between switching on and off, and a faster Sequential Shutdown of the consumer. This is done with a frequency (150 Hz) that the human eye can no longer detect.
