PROBLEM TO BE SOLVED: To solve the following problem in a conventional LED ceiling light having a power supply part installed in its heat radiator: although it is preferable that, in order to reduce the occurrence of power leakage failures as much as possible, an insulating material is interposed between the power supply part and the heat radiator made of metal and further the power supply part is surrounded with the insulating material, insulating properties are degraded and assembling man-hours are increased when the power supply part is fixed to the insulating material with a metallic screw.SOLUTION: An LED ceiling light includes a cup-shaped resin housing member inserted inside of a heat radiation member, and a resin lid member closing an opening of the housing member. While a power supply board is placed on a step portion formed inside of the housing member, a pawl portion is formed projecting on the lid member so that the power supply board is immovably held in the housing member by interpolating the power supply board between the tip of the pawl portion and the step portion in a state in which the opening of the housing member is closed by the lid member. |
