Tuch Sensitive Light Dimmer Circuit

Posted on Feb 6, 2014

With IC SLB0586A from Siemens you can build a simple touch light dimmer circuit that will allow you to adjust the lamp intensity. Together with a TIC206D triac, it enables smooth regulation of light intensity from a bulb of 10W 400W. A coil of 100 µH/5A is required to suppress switching noise. more The voltage supply is obtained through R2, C2

, D1 and C3 and is about 5. 3V below the network potential. The touch sensor that is used to drive the IC is connected at pin 5 through two 4. 7M © resistors, R5 and R6, in order to ensure user security. In the adjustable touch lamp schematic we can see three selection connection, for selecting one of three modes of the IC. When the B connection is used, the light will always be ON at the last level that we used. With A or C connection the light will be ON at the minimum intensity. With B or C, the purpose of regulation is reversed with each use. When the sensor is touched for a short period of time (50 400 ms), the lamp will be ON or OFF. If the sensor is touched for a longer period of time it will start the regulation process.
