Abstract:
A vehicle lamp includes: N semiconductor light sources, wherein N is an integer of 1 or more; M fans configured to cool the N semiconductor light sources, wherein M is an integer of 1 or more; N current supply units configured to supply first current to the N semiconductor light sources, respectively; and a control unit configured to receive electric power supplied from an electric power source and supply second current to the N current supply units. The control unit includes: N switch elements that correspond to the N semiconductor light sources; M switch elements that correspond to the M fans; and a control circuit configured to control fan drive current supplied to the fans through the switch elements and the second current. The fans are coupled to the control unit.
