Hi,
Im a robotics specialist by day which likes to dabble in electronics and CPUs by night. Most of my spare time is put in assembly and C++ programming languages for microprocessors... a big passion of mine! However, electronics intregues very much, however aint no expert due to lack of time.
I am really impressed of such a website where electronic questions can be posted, I just discovered this site this week and this is my 2nd question and by which I deeply thank the guys that answered the first one. My first question was to get a schematic for a 120VAC incandecent dimmer. And I did get one. I really enjoyed looking it over, reading up on it and understanding it. Anyway here is my 2nd question.
I would love to construct a light dimmer which can dim incandecent and halogen lamps. Usually halogen lamps work on 12VAC, so when you supply the 120V, thier usually hooked up to a 120VAC/24VAC transformer.
That being said!... My dilema is that I don't know the principles for a halogen dimmer. You see, I understood the principles of the incandecent one (Firing of triac, phase angle, threshold voltage in the diac which is connected to the gate and soforth....) but are these principles the same for a holagen fixture (Halogen lamp with transformer).
If anyone knows this, I would greatly appreciate an electronic schematic for the holagen dimmer, which basically, the dimmer would have to dim the trasnformer ofcourse since halogens need a transformer.
The idea of me wanting to construct a double function dimmer (For incandecent and halogen lighting) the schematic I would be ultimately looking for would have to be able to dim both lighting mediums. If this is too complicated, I would appreciate any link or reference that could lead to my answer.
Maybe this dimmer will eventually be able to dim fluorecent fixtures also, but thats next year's question!!!!!!!!
Hope I am not to demanding! Thanking all of you in advance once again.
Best regards
Robert
