Document Type and Number:
Japanese Patent JP2011129469
Kind Code:
A
Abstract:
To provide a lighting fixture capable of elongating a life of an LED by efficiently radiating heat to a fixture case via a thermally conductive member jointed to an outer shell of an LED package.
The LED package 21 mounted to a substrate 22 is insertion-fitted into a long hole 32 (32a, 32b) which penetrates the substrate 22, and the heat of the LED is transferred to a heat-radiating sheet 45 as a heat-radiating member arranged at a rear-face side of the substrate 22 through the thermally conductive member 23 in contact with a side face of the LED package 21.
