ABSTRACT:
A control system for an HID lamp, which in one implementation includes a magnetic ballast control system for an HID lamp using Zigbee. A plurality of condensers or choke coils of different capacities is mounted on a magnetic ballast for the lamp, and an electronic switch unit controls illumination according to change of such capacities. RF transmitting/receiving means using a Zigbee-based frequency are employed to turn the HID on and off, and to control illumination through wireless remote communications, thereby achieving considerable energy savings. Operational states of the HID lamp and ballast can be bi-directionally controlled through the communication module, with failures of the HID lamp and ballast automatically detected and notified to users.
