PROTECTION CIRCUIT AND LIGHTING FIXTURE FOR VEHICLE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To keep a main circuit inoperable until a failure factor of the main circuit is removed when the failure of the main circuit is detected.SOLUTION: A protection circuit 90 is provided to protect a main circuit 82. A failure detector 92 detects a failure in the main circuit 82. A fuse 94 is mounted on a power supply path from a power supply 84 to the main circuit 82 and is replaceable. A melting circuit 96 melts the fuse 94 when the failure detector 92 detects a failure.SELECTED DRAWING: Figure 3
