LIGHTING APPARATUS AND DIMMING REGULATION CIRCUIT THEREOF

摘要

The present invention discloses a dimming regulation circuit which stabilizes a rectified voltage in response to an unstable output voltage of a dimmer and a lighting apparatus including the dimming regulation circuit. The dimming regulation circuit stabilizes the rectified voltage and provides the stabilized rectified voltage to a lamp, when a rectified voltage corresponds to a preset stabilization required range.

主权项

1. A dimming regulation circuit of a lighting apparatus, comprising:
a path control circuit configured to perform control according to whether a first rectified voltage corresponds to a preset stabilization necessary range; a first transmission circuit configured to provide a second rectified voltage obtained by stabilizing the first rectified voltage to a lamp including an LED, when the first rectified voltage corresponds to the stabilization necessary range according to control of the path control circuit; and a second transmission circuit configured to refer to the second rectified voltage provided from the first transmission circuit, and provide the second rectified voltage obtained by bypassing the first rectified voltage to the lamp complementarily with the first transmission circuit.
