<P>PROBLEM TO BE SOLVED: To provide a vehicle lamp in which heat generation of a light source unit and a millimeter-wave radar is discharged to the outside of a lamp chamber, and in which electronic components of the millimeter-wave radar can be protected from heat. <P>SOLUTION: The rear-combination lamp 1 has a lamp chamber 5 formed between a lamp body 2 and a front cover 3, and a plurality of light source units 7 and a millimeter-wave radar 6 are installed in the lamp chamber 5. A plurality of LEDs 7a are arranged on the substrate 7b of the light source unit 7, and the substrate 7b is installed on the outer face of a metal case 16 of the millimeter-wave radar 6. A rear-surface aperture 12 of the lamp body 2 is covered by a metallic back cover 13 from the outside of the lamp chamber 5, and the case 16 is fitted, by jointing to a bump portion 18 of the back cover 13. Heat generated from the light source units 7 and the millimeter-wave radar 6 is transmitted to the back cover 13 from the case 16 and is discharged to the outside of the lamp chamber 5 by a heat-radiating fin 14. <P>COPYRIGHT: (C)2010,JPO&INPIT |
