Abstract

A vehicle lamp includes a light source, a lens, and an optical member provided between the lens and the light source. The light source is provided on an attachment surface of a fixing member. The attachment surface includes a pair of fixing portions provided at positions paired with the light source being interposed therebetween and a contact portion provided to protrude from the attachment surface at a position apart from the light source in a direction perpendicular to a straight line connecting two fixing portions. A protruding amount of the contact portion from the attachment surface in an optical axis direction of the light source is greater than that of the fixing portion. A pair of fixing spots provided at one edge portion of the optical member is fixed to the fixing portions, and a contact spot provided at the other edge portion contacts the contact portion.

First claim

The invention claimed is:

1. A vehicle lamp comprising:
a light source provided on an attachment surface of a fixing member;
a lens configured to forwardly irradiate light directly entered from the light source; and
an optical member having a plate shape, provided between the light source and the lens,
wherein the attachment surface includes a pair of fixing portions provided at positions paired with the light source being interposed therebetween and a contact portion provided protrusively from the attachment surface at a position apart from the light source in a direction perpendicular to a straight line connecting the pair of fixing portions,
a protruding amount of the contact portion from the attachment surface in an optical axis direction of the light source is greater than that of each of the pair of fixing portions,
the optical member is provided with a pair of fixing spots provided at one edge portion of the optical member and a contact spot provided at another edge portion of the optical member, the pair of fixing spots being fixed to the pair of fixing portions through a fastening member, and the contact spot contacting the contact portion,
the optical member is configured such that a pair of attachment pieces having the pair of fixing spots is connected to each other through a coupling piece, and
the contact spot is provided at a coupling-piece-side end portion of the pair of attachment pieces, and is formed in a protruding piece shape such that only one of four sides crossing each other is connected to the pair of attachment pieces.

2. The vehicle lamp according to claim 1 , wherein
the coupling piece includes a bent piece bent toward an attachment surface side, and
the bent piece is chamfered at a spot facing the light source in the optical axis direction.

3. The vehicle lamp according to claim 1 , wherein
the fixing member is a heat radiation member configured to radiate heat from the light source, and is provided with multiple heat radiation fins on a rear surface of the attachment surface, and
the pair of fixing portions set a position of the optical member with respect to the light source in the optical axis direction while receiving the fastening member in such a way that the fastening member does not protrude to a rear side of the fixing member.
