<P>PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture capable of attaining output stability and lifetime extension of a light source while reducing the number of components. <P>SOLUTION: In the vehicular lighting fixture wherein a plurality of LEDs (light source) 6 mounted on a heat sink 7 are stored in a housing, LED mounting seat surfaces 7A to each of the plurality of LEDs 6 are arranged on the heat sink 7, a heat transmitting route L1 between two adjacent LEDs 6 is set up to be a curved line on the LED mounting seat surface 7A, and the heat sink 7 is integrated. For example, the LED mounting seat surface 7A is divided into a plurality of pieces by forming a slit 9 between two adjacent LEDs 6 on the LED mounting seat surface 7A of the heat sink 6, and two divided LED mounting seat surfaces 7A1, 7A2 are combined and integrated by connecting heads of respective heat-radiating fins 7B. <P>COPYRIGHT: (C)2011,JPO&INPIT |
