Abstract
Provided is a vehicle lamp in which heat is less likely to be trapped and thermal deformation of a condenser lens and a projection lens is prevented. A vehicle lamp includes a light source unit, a support portion, a condenser lens, a light blocking member, and a projection lens. A first lens portion, a first lens peripheral wall portion, and the light blocking member (shade portion) form a first space. A second lens portion, a second lens peripheral wall portion, and the light blocking member (shade portion) form a second space. An upper portion of at least the first lens peripheral wall portion or the second lens peripheral wall portion has an upper opening (upper opening of first lens peripheral wall portion, upper opening of second lens peripheral wall portion).
Claims7
A vehicle lamp comprising:
- a light source unit;
- a support portion that supports the light source unit;
- a condenser lens that collects light emitted from the light source unit;
- a light blocking member that has an irradiation slit that allows part of the light collected by the condenser lens to pass through;
- and
- a projection lens that projects the part of the light passing through the light blocking member to form an irradiation pattern, wherein
- the condenser lens has a first lens portion, and a first lens peripheral wall portion that extends from the first lens portion as a bottom,
- the projection lens has a second lens portion, and a second lens peripheral wall portion that extends from the second lens portion as a bottom,
- the first lens portion, the first lens peripheral wall portion, and the light blocking member form a first space,
- the second lens portion, the second lens peripheral wall portion, and the light blocking member form a second space, and
- an upper portion of at least one of the first lens peripheral wall portion and the second lens peripheral wall portion has an upper opening.
