## Abstract

An illumination device to be mounted on a vehicle, includes a light source; a sensor configured to acquire information outside the vehicle based on invisible light; and a cover including a first portion covering the light source and a second portion covering the sensor. The second portion has a lower visible light transmittance than the first portion.

## Claims

### Claim 1

An illumination device to be mounted on a vehicle, comprising:
a light source;
a sensor configured to acquire information outside the vehicle based on invisible light; and
a cover including a first portion covering the light source and a second portion covering the sensor,
wherein the sensor is configured to receive light through a part of the second portion that has a lower visible light transmittance than the first portion.

### Claim 2 (depends on 1)

The illumination device according to claim 1, wherein the sensor is installed on the cover.

### Claim 3 (depends on 1)

The illumination device according to claim 1, wherein the first portion and the second portion are integrally molded.

### Claim 4 (depends on 1)

The illumination device according to claim 1, wherein the sensor is a LiDAR sensor.

### Claim 5 (depends on 1)

The illumination device according to claim 1,
wherein the cover includes a third portion disposed to face a front and rear direction of the vehicle and a fourth portion disposed to face a left and right direction of the vehicle, and
wherein the second portion is located at a side end portion of the fourth portion remote from the third portion.

### Claim 6 (depends on 1)

The illumination device according to claim 1,
wherein the cover includes a third portion disposed to face a front and rear direction of the vehicle and a fourth portion disposed to face a left and right direction of the vehicle, and
wherein the second portion is located at a side end portion of the third portion remote from the fourth portion.

### Claim 7 (depends on 1)

The illumination device according to claim 1,
wherein the cover includes a third portion disposed to face a front and rear direction of the vehicle and a fourth portion disposed to face a left and right direction of the vehicle, and
wherein the second portion is located at an upper end portion of the third portion.
