  • Patent number: 9915407
    Abstract: Disclosed is a vehicular lamp including: a lamp outer case including a lamp housing having an opening and a cover configured to close the opening; a first board mounted with a first light source package; a second board mounted with a second light source package; and an optical member mounted with the first board and the second board. The first board and the second board are different kinds of boards that have different heat dissipation performances. Since the heat dissipation property for the heat generated when the first light source package is driven and the heat dissipation property of the heat generated when the second light source package is driven becomes different from each other, the heat dissipation performances may be properly controlled depending on an irradiation state.
