PROBLEM TO BE SOLVED: To reduce assembly man-hour of a fixture in a lighting fixture and radiate heat inside the fixture efficiently to the outside without installing separately a heat radiating member.SOLUTION: A lighting fixture 1 is provided with a light source 6, a lighting control section 7 for controlling lighting of the light source 6, an mounting base 8 which holds the light source 6 and the lighting control section 7, and a casing 9 which houses these members. The mounting base 8 is a long square tube shape structured of a material having a high heat radiation characteristics, and has the light source 6 on one surface of an outer circumference thereof and the lighting control section 7 on one surface of the inner circumference thereof. Since the light source 6 and the lighting control section 7 are installed on the mounting base 8, the light source 6 and the lighting control section 7 can be made integrated with the mounting base 8, thereby, a number of members is reduced and a man-hour in assembly of the lighting fixture 1 can be reduced. Further, since the mounting base 8 is structured of a material having heat radiation characteristics, and is made a square tube shape with a large surface area, heat inside the lighting fixture 1 can be radiated efficiently to the outside without installing separately a radiating member. |
