Examples of the yellow phosphor include a YAG (yttrium, aluminum, garnet) phosphor material, a silicate phosphor material, and the like. An example of the resin carrying the phosphor in a dispersed state is a silicone resin.

  The substrate 301 is a long plate-like member in which the first light source 321 and the second light source 322 are attached to the surface, and the longitudinal direction is arranged along the arrangement axis A. For example, the substrate 301 is made of a ceramic substrate such as aluminum nitride having translucency. Note that the material of the substrate 301 is not limited, and a resin, glass, or the like may be used as long as the material has insulating properties. Further, the substrate 301 is not limited to a rigid body, and may be a flexible substrate having flexibility.

  By making the case 200 into the above-described shape, it is possible to easily obtain the case 200 by forming a long member by extruding (drawing) the case 200 and cutting out the member. Moreover, since the length of the housing | casing 200 can be changed only by changing the position to cut out, the lamp | ramp 100 from which length differs can be manufactured easily. In particular, in combination with the substrate 301 having the above structure, the lamps 100 having different lengths can be easily manufactured.

In the case of the present embodiment, the rotating part 223 receives the first engaging part 221 and guides it to the rotating part 223, from the slit 225 to the second engaging part 222, over the entire range of 90 degrees around the rotation axis C. Is provided. Therefore, in the state where the lamp 100 and the base body 703 are engaged, the rotation angle at which the lamp 100 rotates with respect to the base body 703 is determined by the rotating unit 223 and is selected from the range of 0 degree or more and less than 270 degree. 90 degrees is set.

  And the direction with respect to the base | substrate 703 of the optical axis B is determined by the 2nd engaging part 222 and the 1st engaging part 221 which are provided in the edge part of the rotation part 223 engaging. In the case of the present embodiment, the optical axis B is set to be perpendicular to the main surface 705 of the base 703 by the engagement of the first engagement portion 221 and the second engagement portion 222.
