Lighting control circuit, lamp, and lighting control method using the lighting control circuit
Abstract:
A lighting control circuit includes a rectifier connected to an electric ballast to which a commercial AC power is supplied, and configured to convert an AC to a DC, a series light emitter a plurality of solid-state light-emitting elements is connected in series, a smoothing capacitor provided in parallel with the series light emitter in a current supply line between the rectifier and the series light emitter, and configured to eliminate an AC component included in the DC from an output side of the rectifier, and a switching control circuit configured to generate an output voltage equal to an output voltage from the electric ballast when a fluorescent lamp starts up upon the connection of the fluorescent lamp to the electric ballast as a startup voltage in the startup of the series light emitter.
