Patent ID: 7164235

Claim:
A vehicular lamp, comprising: a plurality of semiconductor light emitting devices connected in parallel; a plurality of current limiting units provided corresponding to said plurality of semiconductor light emitting devices, wherein said plurality of current limiting units connect with said corresponding semiconductor light emitting devices respectively in series, and limit electric current flowing through said corresponding semiconductor light emitting devices respectively; and a current control unit for changing electric current to be supplied to at least one of said plurality of semiconductor light emitting devices; wherein when a wire of one of said plurality of semiconductor light emitting devices is broken, said current control unit increases the electric current to be supplied to at least one of said plurality of semiconductor light emitting devices of which a wire is not broken by causing at least a part of the electric current to flow via a path connected in parallel with corresponding one(s) of said plurality of current limiting units, wherein said plurality of current limiting units comprise a plurality of series resistances respectively connecting with said plurality of semiconductor light emitting devices in series so that at least a part of the electric current to be supplied to each of said plurality of semiconductor light emitting devices flows through corresponding one of said plurality of series resistances, each of said plurality of series resistances comprises a terminal located closest to corresponding one of said plurality of semiconductor light emitting devices, said current control unit comprises a terminal connecting unit connecting said plurality of terminals with one another.
