Abstract
In a lamp unit (1), a conductive section (2) is formed by directly extending a layer structure of a reflective member (42) from (i) one end of a square U-shape of a part of the reflective member (42) that is closest to a power feeding section for feeding power to the lamp unit (1) toward (ii) a light emission side of the lamp unit (1) and further folding back the extended portion 180 degrees in a direction opposite to the direction that it extends from the reflective member (42). The conductive section (2) is provided with a screw hole (2a) through which the reflective member is connected to another object. This achieves a lamp unit in which, even if a reflective member is fixed to another object with a screw for conduction with an external conductor, a reflective layer is less likely to peel off.

A lamp unit
- including (i) a lamp for emitting light
- and (ii) a reflective member, provided around the lamp, which has a stack of a sheet metal and a reflective layer that reflects at least a part of the light outward, the lamp unit comprising:
- a folded section formed by folding back the reflective member 180 degrees such that the reflective layer is positioned inside the sheet metal,
- the folded section being provided with a screw hole through which the reflective member is connected to another object other than the lamp unit in the folded section
- in a state where the folded section is connected to said another object with a screw through the screw hole, the reflective layer in the folded section being in no contact with said another object, and the sheet metal in the folded section being in contact with said another object.
A lamp unit
