紅外燈調光器電路

If you have chosen which remote controller keys will be used as controlling keys, we can start with memorizing process. Press and hold button until lights go 3 times to maximum. After that, light will turn OFF, and that is indication of successful entering “memorizing the remote controller keys” mode, then you can release button. In the next 5 seconds, you must press the first key on remote controller, if you do, lights will blink several times. After that, you must press the second remote controller key, if you do, lights will also blink several times. That’s all, memorizing process is finished.

You can change the assigned remote controller keys when you wish. After powering down the Ir LightDimmer, it will keep in memory these remote controller keys, so you don’t have to memorizing remote controller keys again when the device powers up.

Ir LightDimmer is a small device (36*32mm) and can be easily mounted in electrical case where electrical wires terminate. Device works only with 220V/50Hz and only for resistive loads of 40W-400W. With Ir LightDimmer you can’t use inductive or capacity loads (only bulbs). Device is based on PIC12F629 which is a small microchip microcontroller and therefore overall device is small and uses a few components. On circuit board you can find the IR-receiver, which in our case is TSOP1738, but you can use any other type of IR-receiver which has frequency of 38KHz. For output power stage you can use triac TIC206 or TIC216. For loads more than 150W you must add a heat sink on triac. The rest of parts are defined in schematic.

You must be careful when you connect IrLightDimmer to electrical wire, so you must break fuse switches of your lights. All connections must be like in my schematic, otherwise device will definitive burn out.

If you have IrLightDimmer mounted and connected and you want to change your lights, you must break fuse switches because there is risk of electric shock.
