PROBLEM TO BE SOLVED: To provide a lamp capable of changing light distribution without greatly changing an external dimension of the lamp, with a simple structure.SOLUTION: A lamp includes: a plurality of light source units 2; a lamp body 3; and a light source unit support body 4 having fixing surfaces 4c, 4d, 4e where the light source units 2 are fixed and supporting the light source units 2 with respect to the lamp body 3. The plurality of light source units 2 are arranged around a lamp center axis, and between the adjacent light source units 2, there is a gap for air to pass through. The light source unit support body 4 has the plurality of fixing surfaces 4c, 4d, 4e in which angles are different with respect to the lamp center axis, and an inclination angle of the light source unit 2 can be changed with respect to the lamp center axis by fixing the light source unit 2 to the light source unit support body 4 by selecting one of the plurality of fixing surfaces 4c, 4d, 4e. |
