Homemade 20W fluorescent lamp dimmer circuit diagram

Published:2011/4/6 21:39:00 Author:Ecco | Keyword: Homemade , 20W, fluorescent lamp , dimmer

Homemade 20W fluorescent lamp dimmer Using the method of connecting capacitor in series can easily control the brightness of fluorescent lamps. To adapt to different lighting requirements. Figure 28 is a modified circuit diagram. When the switch connects to the 1 , the brightness of the lamp is normal, the actual power is 20w; and connects to 2 , brightness is medium, power is about 10w; and connects 3 , the brightness is faint, and the power of about 5w. We should pay attentionon the lamp must belit properly before dimming. Dimming dial switching action must be fast, or the light will be turned off when the switch opening too long, and the switch needs to re-start.   (View)

The circuit diagram of light signal receiving

Published:2011/3/29 20:03:00 Author:Ecco | Keyword: light signal receiving

This circuitry adopts the photoelectric cell IR-B2 M type to receive semaphore. Optics semaphore can be optical light or infrared light, and it takes the LED or semiconductor laser machine as light source, and the municipally frequency should be 0.5~2.0 KHZ. When the photocell is irradiated, it can produce quadrature voltage and be amplifiered by Q1, Q2, then the voltage will pass a output transformer which mutually matches with earphone impedance. Consequently, we can use earphone to hear the sound clearly.   (View)
