Filed: 2012-06-13
Abstract: PROBLEM TO BE SOLVED: To provide an LED lighting fixture in which heat radiation performance of a substrate mounted with an LED unit is improved and insulation properties of the substrate can be secured.SOLUTION: A substrate 34 mounted with an LED unit 33 is installed on a fixture body 30 through a thermal conductive sheet 37.

Thereby, a contact area between the thermal conductive sheet 37 and the substrate 34 can be increased, and also, the heat radiation performance radiated from the substrate 34 through the thermal conductive sheet 37 can be improved. Further, since the thermal conductive sheet 37 reaches from one face 371 of the substrate 34 to the other face 341 through the end face 372, it does not move against the substrate 34. As a result, since the insulation distance between the substrate 34 and the fixture body 30 becomes long, insulation properties of the substrate 34 can be secured.
