Title:
VEHICULAR LED LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2008078088
Kind Code:
A
Abstract:

To provide a vehicular LED lighting fixture using LEDs for light sources, in which temperature rise in LED light sources is suppressed by increasing the heat radiation properties of the self generated heat of the LED light sources and the predetermined quantity of light irradiation is secured by reducing a decrease in luminous efficiency in the LED light sources.

A lamp chamber 15 is mainly formed of a front surface lens 13 and a housing 14. A lamp unit 3 having an LED light sources 21, a heat sink portion 8 and so on, and a lamp unit 1 united with a bracket 4 are disposed in the lamp chamber 15. Thus, the self generated heat of the LED light sources 21 while they are lit is radiated by the heat sink portion 8 and the bracket 4 to suppress temperature rise in the LED lighting fixture 21, and the predetermined quantity of light irradiation required for a vehicular LED lamp fixture 24 is secured.
