Ir Light Dimmer v.2

• two ways to control light: either with button on dimmer or with remote controller
• soft start - lights change state slowly, so your bulbs will have longer life duration
• soft stop
• You can change the assigned remote controller keys when you wish
• with adjusting light intensity you save on electrical energy.
• “double click” mode - the lights go ON to 70%, and slowly decreasing light intensity to minimum in a period of 1 minute.

Electronics of Ir Light Dimmer v.2 is constructed with two part of circuit boards, because it's small space inside of used switch. On back side you can see circuit board with two connections (picture above).
Used switch is made by Gewiss and in their offer you can find frames in different colours (picture above).

On left picture is a front circuit board with Ir-receiver TSOP2238 and small microswitch for manual adjusting lights. Characteristic of microswitch is that you can't broke him with pression, and current through him is very small, so he will have longer life duration.
The biggest current flow through triac TIC216, and hard of device is ordinary microchip PIC12F629.
Microcontroller is in soic package, and circuit board is made in two layer technology.

On left picture you can see how is wired Ir LightDimmer v.2 .

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 ON or OFF lights, but if we press and hold the button more than 300ms the light intensity is increasing to maximum or decreasing to minimum continuously until you press the button. If we press and hold the button so that lights go to maximum 3 times, then device enters “memorizing the remote controller keys” mode.

Using remote controller key to control the dimmer you can turn on lights or increase light intensity. With a short press, lights turn ON to maximum and if you press and hold key then light intensity increases until you press that key.

The same thing happens with second remote controller key which is used to turn lights off or decrease light intensity. When you short press that key, the lights will turn OFF and if you press and hold key then light intensity decrease until you press that key.

When turning lights ON or OFF they are not reacting immediately but they change state slowly so your bulbs will have longer life duration. Also with adjusting light intensity you save on electrical energy.

“double click” mode (like PC mousses):
so, when you double click the push-button, the lights go ON to 70%, and slowly decreasing light intensity to minimum in a period of 1 minute. This mode is good for your bedroom, so when you go to sleep just double click the button and go to bed. If you don’t like to wait lights to go OFF in 1 minute, you can break this mode by pressing button or by pressing remote controller keys.

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 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 Light Dimmer v.2 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).
