WIPO Patent Application WO/2016/135769
Kind Code:

Abstract:
The purpose of the present invention is to obtain an illumination lamp in which variation in the relative position of a light source with respect to a cover is suppressed. This illumination lamp is characterized by being provided with: a light source module 3 in which a light source 4 is provided to a surface parallel to the length direction; a light-source-side positioning part 67, i.e. a groove which is formed in the surface of an arc part 64 positioned at the opposite side to the light-source-module 3 surface having the light source 4 provided thereto, and in which a valley part 67b sandwiched between a pair of slanted surfaces 67a is formed along the length direction; a cylindrical cover 2 which holds the light source module 3 therein such that the inner circumferential surface faces the surface of the light source module 3 in which the light-source-side positioning part 67 is formed; and a cover-side positioning part 23, i.e. a protrusion which is formed in a position of the inner circumferential surface of the cover 2, said position facing the light-source-side positioning part 67, and which has a ridge part 23a formed at the tip. The illumination lamp is further characterized in that the ridge part 23a and a valley part 23b are brought into contact with each other.
