METAL HALIDE LAMP BALLAST CONTROLLED BY REMOTE ENABLE SWITCHED BIAS SUPPLY |
摘要 |
A vehicle lighting system receives power from a power supply and includes a lighting control module, a lamp, and a ballast having a bias control circuit. The lighting control module provides a remote enable signal to the ballast in response to an input. The bias control circuit of the ballast receives a supply voltage from a power supply and the remote enable signal and selectively energizes a bias regulator circuit of the ballast as a function of the remote enable signal. When the bias regulator circuit is energized, a controller of the ballast operates the ballast to provide power from the power supply to the lamp. |
