<P>PROBLEM TO BE SOLVED: To provide a vehicular LED lamp capable of securing a predetermined quantity of irradiation light by suppressing temperature rise of an LED light source by enhancing heat radiation capability against self-heating of the LED light source, and thereby reducing deterioration of emission efficiency of the LED light source, in a vehicular LED lamp using LEDs for a light source. <P>SOLUTION: In a lamp unit 5 supported in a lamp chamber formed with a front lens and a housing, a mount plate 7 with a mounting board of the LED light source 6 mounted thereon, a reflector 8 connected to the mount plate 7, and a heat sink 12 similarly fixed to the mount plate 7 are each formed of a material having high thermal conductivity, and the reflector 8 is provided with a radiation fin 15 formed of a material having high thermal conductivity. <P>COPYRIGHT: (C)2008,JPO&INPIT |
