Abstract
A lamp dimmer system for dimming multiple lamps in a room having unswitched receptacles, and switched receptacles under control of a single wall switch. A user control module connected to an unswitched receptacle transmits momentary wireless brightness command signals in response to user-actuation of a brightness control. Each lamp in the room includes a lamp control module connected to both the unswitched and switched receptacles and to the lamp. The lamp control modules include a receiver which receives the brightness command signals and a control circuit which generates a steady state brightness control signal in response to the momentary command signals. A dimmer circuit responsive to the brightness control signal, and connected between the unswitched receptacle and the lamp, controls the power supplied to the lamp according to the level of the brightness control signal. An AC detector circuit within the lamp control module and connected to the switched receptacle conditions the dimmer circuit to full brightness upon the wall switch being switched on, and to minimum brightness upon the wall switch being switched off, thereby enabling normal operation of lamps by the wall switch.
