Abstract

To provide a light device that can suppress the heat influence. In a tail light having LED chips, an electronic component that turns on the LED chips, and a first substrate, and a second substrate, and a third substrate on which the LED chips and the electronic component are disposed, a plurality of the first substrate, the second substrate, and the third substrate are independently provided, and are spaced from one another.

First claim

The invention claimed is:

1. A light device, comprising:
a light source;
an electrical element that turns on the light source;
substrates on which the light source and the electrical element are disposed, a plurality of the substrates being independently provided, and being disposed to be spaced from one another;
a column to which the substrates are fixed;
a housing that supports the column;
an outer lens that, together with the housing, forms a housing portion for housing the plurality of substrates; and
an inner lens that is provided inside the outer lens, and is disposed between the plurality of substrates and supported by the column,
wherein
the outer lens includes a lens cut portion that is a part of the outer lens and that has been subjected to lens cut processing, and the inner lens includes a lens cut portion in a position that does not overlap with the lens cut portion of the outer lens in a rear view,
in the rear view, the lens cut portion of the outer lens is provided in a center portion of the outer lens, the lens cut portion of the inner lens is provided in the inner lens on both sides of the lens cut portion of the outer lens, and the substrate disposed between the outer lens and the inner lens is disposed on an inner side of a contour of the lens cut portion of the outer lens.

2. The light device according to claim 1 , further comprising:
a partition portion that is fixed to the column, and is disposed between the plurality of substrates.

3. The light device according to claim 1 , wherein
the outer lens is a tail lamp, and includes a light transmitting portion in a part of a bottom surface of the outer lens, the light transmitting portion transmitting light of the light source to illuminate a license plate attached to a rear portion of a vehicle body, and
a boundary between the light transmitting portion and a lower portion of the housing is located in front of an upper boundary with respect to the vehicle body, the upper boundary being provided between the outer lens and the housing.
