Lamp Dimmer


Posted on Feb 6, 2014

This project is a wonderful idea of saving electric bill when you are using a heavy wattage bulbs. With miniature components and extreme care you can build a low power lamp dimmer right into the socket. Instead of a relativity expensive trigger diode, an ordinary neon lamp of the NE-83 or NE-2 variety can be used. (An NE-83 is treaded for dark ope

ration and will provide more consistent operation. ) Because the neon does not trip the gate until it conducts, the lamp turns on at medium brilliance. The lamp can then be backed off to a soft glow. Because the neon drops out when the applied voltage falls below the neon holding voltage of approximately 40V the lamp cannot be adjusted as low as it can with a diode trigger.
