Light source control device |
摘要 |
A light source control device comprises a first bypass switch connected in parallel to one part of semiconductor light sources, and a second bypass switch connected in series to the first bypass switch and in parallel to another part of the semiconductor light sources. In a connection line connecting a connection node between the first and the second bypass switches and a connection node between the one part and the another part of the semiconductor light sources, a polarity of a current flowing in the connection line when the first bypass switch is off and the second bypass switch is on is opposite to a polarity of the current flowing in the connection line when the first bypass switch is on and the second bypass switch is off, When a poor continuity is generated in the connection line, the first and the second bypass switches are forcedly turned on. |
