Title:
ELECTRONIC BALLAST DEVICE FOR UNINTERRUPTED LIGHTING OF HID LAMP
Document Type and Number:
WIPO Patent Application WO/2008/022549
Kind Code:
A1
Abstract:
An electronic ballast device for uninterrupted lighting of HID lamp, comprises:
an input unit, an output unit and an UPS unit for uninterrupted supplying power
to HID lamp when the power network switches or instantaneous-dropping dithers,
wherein the input unit and the output unit are serially connected by two branch
circuits, the one is that the input unit are directly serially connected to the
output unit, the other is that the UPS unit is set to be serially connected between
the input unit and output unit. As a result, uninterrupted lighting will be implemented
when the power network switches, and the irreversible damages to relating electronic
components and lamp due to extra high voltage triggering can be completely eliminated.
