1. An in-vehicle illumination device, comprising:
- a room lamp section, including a first light source section, and a light guide plate guiding a light of the first light source section from an end surface of the light guide plate and emits the light from a front surface of the light guide plate;
a map lamp section, including a second light source section, and a lens that converges a light of the second light source section;
a first switch used for the room lamp section;
a second switch used for the map lamp section; and
a heat sink member incorporated with a light source of the first light source section and a light source of the second light source section.

Abstract
In an in-vehicle illumination device including: a room lamp section provided with a first light source section and a light guide plate, a map lamp section provided with a second light source section and a lens, a first switch for use by the room lamp section, and a second switch for use by the map lamp section, a light source configuring the first light source section and a light source configuring the second light source section are mounted on any same heat sink member. In the resulting in-vehicle illumination device, measures are taken against heat generation, and the reduction of size and weight is achieved. The design quality of the illumination device can be also improved.

14. An in-vehicle illumination device, comprising:
-
a room lamp section, including a first light source section, and a light guide plate guiding a light of the first light source section from an end surface of the light guide plate and emits the light from a front surface of the light guide plate; a map lamp section, including a second light source section, and a lens that converges a light of the second light source section; a first switch used for the room lamp section; a second switch used for the map lamp section; a heat sink member incorporated with a light source configuring the first light source section, and a light source configuring the second light source section; and a vanity mirror section including a mirror, wherein the first light source section is turned on when the vanity mirror section is in use, and a mode change is made to a vanity-mirror illumination mode in which the room lamp section emits an illumination light, wherein the vanity mirror section includes an open/close lid, and wherein a mode change is made to the vanity-mirror illumination mode when the first light source section is under turn-on control through operation of the first switch, and when the lid is in an open state in response to turn-on control associated with an open/close operation of the lid.

15. An in-vehicle illumination device, comprising:
-
a room lamp section, including a first light source section, and a light guide plate guiding a light of the first light source section from an end surface of the light guide plate and emits the light from a front surface of the light guide plate; a map lamp section, including a second light source section, and a lens that converges a light of the second light source section; a first switch used for the room lamp section; a second switch used for the map lamp section; a heat sink member incorporated with a light source configuring the first light source section, and a light source configuring the second light source section; and a vanity mirror section including a mirror, wherein the first light source section is turned on when the vanity mirror section is in use, and a mode change is made to a vanity-mirror illumination mode in which the room lamp section emits an illumination light, and wherein an illumination light at the time of the vanity-mirror illumination mode is not the same as an illumination light at the time of a room-lamp illumination mode in which the vanity mirror section is not in use, and when the room lamp section is in a turn-on state.
