Abstract

A vehicle lamp includes an optical unit and a light source control circuit part. The optical unit is unitized by attaching a light source and an optical member to an attachment part. In a state where the optical unit is unitized, the light source control circuit part is attachable to the attachment part in a direction in which the light source and the optical member are not disposed.

Claims

1. A vehicle lamp, comprising:

an optical unit that is unitized by attaching a light source and an optical member to an attachment part; and

a light source control circuit part, wherein

in a state where the optical unit is unitized, the light source control circuit part is attachable to the attachment part in a direction in which the light source and the optical member are not disposed.

2. The vehicle lamp according to claim 1, wherein

the optical member includes

a lens disposed on a lamp front side of the light source, and

a reflector disposed so as to cover an upper portion of the light source,

a heat sink is provided on an opposite side to a surface, to which the light source (21) is attached, of the attachment part, and

the light source control circuit part is disposed adjacent to the heat sink on a lamp front side of the heat sink.

3. The vehicle lamp according to claim 1, wherein

the optical unit and the light source control circuit part are disposed in a lamp chamber formed by a lamp body and a transmissive cover, and

a portion of the lamp body corresponding to a direction in which the light source and the optical member are not disposed is openable.

4. The vehicle lamp according to claim 2, wherein

the optical unit and the light source control circuit part are disposed in a lamp chamber formed by a lamp body and a transmissive cover, and

a portion of the lamp body corresponding to a direction in which the light source and the optical member are not disposed is openable.

5. The vehicle lamp according to claim 3, wherein a lamp-lower-side portion of the lamp body is openable.

6. The vehicle lamp according to claim 4, wherein a lamp-lower-side portion of the lamp body is openable.
