BALLAST CONTROL SYSTEM FOR HID LAMP USING ZIGBEE
First Claim
1. A constant power type magnetic ballast control system for a HID lamp, the system comprising:
- a management system module for outputting HID lamp control signals on the basis of Zigbee communications;
a wireless control module for controlling the HID lamp by bi-directionally communicating with the management system module; and
a constant power type magnetic ballast unit provided with a plurality of power factor improving condensers to be selected by the wireless control module, for stably supplying power.

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, thereby eliminating inconvenient confirmation processes. The magnetic ballast control system is useful in street lamps, tunnel lamps, factory lamps, warehouse lamps, landscape illuminations, and the like.
