Abstract

A lamp device to be mounted on a vehicle includes a housing, a translucent member defining a housing space together with the housing, a light source housed in the housing space, and a sensor housed in the housing space and configured to detect information outside the vehicle. The translucent member includes a first portion and a second portion. The first portion includes a region through which light emitted from the light source passes and has first weather resistance. The second portion includes a region opposing the sensor and has second weather resistance, and the second weather resistance is higher than the first weather resistance.

Claims

1. A lamp device to be mounted on a vehicle, the lamp device comprising:

a housing;

a translucent member defining a housing space together with the housing;

a light source housed in the housing space; and

a sensor housed in the housing space and configured to detect information outside the vehicle,

wherein the translucent member includes a first portion and a second portion,

wherein the first portion includes a region through which light emitted from the light source passes and has first weather resistance, and

wherein the second portion includes a region opposing the sensor and has second weather resistance, and the second weather resistance is higher than the first weather resistance.

2. The lamp device according to claim 1, further comprising:

an opaque member covering at least one part of a first end edge of the first portion and at least one part of a second end edge of the second portion.

3. The lamp device according to claim 1, further comprising:

an opaque member having a portion which is flush with at least one of (i) at least one part of a first end edge of the first portion and (ii) at least one part of a second end edge of the second portion.

4. The lamp device according to claim 2,

wherein the opaque member presents a same color as a part of a vehicle body of the vehicle.

5. The lamp device according to claim 1,

wherein the second portion is smaller than the first portion.

6. The lamp device according to claim 1,

wherein the second portion includes a portion having a lens function.

7. The lamp device according to claim 1,

wherein the first portion and the second portion are a part of an integral molded product.

8. The lamp device according to claim 1,

wherein the sensor includes at least one of a LiDAR sensor, a millimeter wave radar, an ultrasonic sensor, and a camera.

9. The lamp device according to claim 1,

wherein the second portion is made of either one of glass, acrylic resin, and bio-polycarbonate resin.
