Document Type and Number:
Japanese Patent JP2017208171
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lighting fixture capable of securing a sufficient insulation distance and contributing to the miniaturization of the lighting fixture.SOLUTION: The lighting fixture has: a light source module 33 having a plurality of semiconductor light emitting elements 33c; a heat radiation sheet 34 having thermal conductivity; and a plate-like spacer 35. In the case where the main emission direction of light from the plurality of semiconductor light emitting elements 33c is set downward, the spacer 35 has a light source module arrangement region 35b1, in which the light source module 33 is arranged, in a lower surface 35b, and has a heat radiation sheet arrangement area 35a1, in which the heat radiation sheet 34 is arranged, in the upper surface 35a. In a plan view, the center of each of the light source module 33 and the heat radiation sheet 34 is located on one virtual straight line X2 along the vertical direction.SELECTED DRAWING: Figure 7
