ABSTRACT:
A fluorescent lamp control circuit includes a dimmer and a sensor. The dimmer is electrically connected in parallel with the fluorescent lamp. The sensor is electrically connected in parallel with the dimmer and lamp. The dimmer adjustably controls the brightness of the lamp when an operating voltage is applied to the lamp. The sensor electrically disables the dimmer when a starting voltage is applied to the lamp and electrically enables the dimmer when an operating voltage is applied to the lamp. The sensor includes a voltage controlled switch, a voltage regulator, a direct current power supply, and a voltage controlled trigger. An output of the voltage regulator is electrically connected to an input of the voltage controlled switch. The voltage controlled trigger is electrically connected between an output of the direct current voltage supply and an input of the voltage regulator. The dimmer includes a current controlled switch, a variable phase-shift (RC) network, and a voltage controlled switch. The voltage controlled switch is electrically connected between an output of the variable phase-shift (RC) network and an input of the current controlled switch.
