Vehicular lamp
First Claim
1. A vehicular lamp, comprising:
- a plurality of semiconductor light emitting devices connected in parallel;
a wire breakage detecting unit detecting wire breakage of each of said plurality of semiconductor light emitting devices; and
an electric current supplying unit supplying a first electric current to said plurality of semiconductor light emitting devices, wherein said electric current supplying unit decreases the electric current to be supplied to said plurality of semiconductor light emitting devices from the first electric current to a second electric current, which is lower than the first electric current, when said wire breakage detecting unit detects wire breakage of at least one of said plurality of semiconductor light emitting devices.

Abstract
Electric current supplied to light source rows of a vehicular lamp is controlled appropriately. The vehicular lamp includes: a plurality of semiconductor light emitting devices connected in parallel; a wire breakage detecting unit detecting wire breakage of each of the plurality of semiconductor light emitting devices; and an electric current supplying unit supplying a predetermined electric current to the plurality of semiconductor light emitting devices. The electric current supplying unit decreases the electric current to be supplied to the plurality of semiconductor light emitting devices when the wire breakage detecting unit detects wire breakage of at least one of the plurality of semiconductor light emitting devices.
