Title:
DIMMING BALLAST DEVICE OF ELECTRODELESS LAMP
Document Type and Number:
WIPO Patent Application WO/2011/113354
Kind Code:
A1
Abstract:
A dimming ballast device (20) of an electrodeless lamp, used in an electrodeless lamp (30) and a direct-current voltage (40), includes a frequency converting unit (208), a control unit (210) and a dimmer signal output unit (212). The control unit (210) is electrically connected to the frequency converting unit (208), and the dimmer signal output unit (212) is electrically connected to the control unit (210). After receiving a negative feedback signal output from the frequency converting unit (208) and a signal output from the dimmer signal output unit (212), the control unit (210) sends a control signal to the frequency converting unit (208). By means of said control signal, said frequency converting unit (208) converts the direct-current voltage (40) into a driving alternating-current dimming signal so as to drive the electrodeless lamp (30) to lighten and adjust light. Said dimming ballast device (20) can adjust the light of the electrodeless lamp so as to increase the practicality of the electrodeless lamp.
