红外灯调光器电路,IR Light Dimmer

This is a device for adjusting lights in your home with any type of remote controller (tv, dvd, video,). Today we are using many devices in our homes to improve quality of our life and this is another example height=394 src="/data/attachment/portal/201007/ET33174201007230144171.jpg" width=634 border=0 红外灯调光器电路 396px? ?

How it works

We have two ways to control light: either with push-button or with remote controller. Using the push-button, when we apply a short press we can turn> 

Memorizing the remote controller keys

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 src="/data/attachment/portal/201007/ET33174201007230144175.gif" width=181 border=0 name=dimmer0>

Ir LightDimmer is a small device (36*32mm) and can be easily mounted in electrical case where electrical wires terminate. Device works src="/data/attachment/portal/201007/ET33174201007230144176.gif" width=183 border=0 name=dimmer1>

With Ir LightDimmer you can’t use inductive or capacity loads (only bulbs). Device is based src="/data/attachment/portal/201007/ET33174201007230144177.gif" width=180 border=0 name=spajanje>

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>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.
