Technical Field

The present invention relates to a vehicle interior lighting device and a roof module.

Background

Disclosure of Invention

Technical problem to be solved by the invention

In vehicles, it is desirable to enable novel lighting. For example, if a visual effect that light appears to float in the air can be achieved, the user can be made to feel novelty.

The invention aims to provide an indoor lighting device for a vehicle and a roof module, which can realize illumination with novel feeling.

Means for solving the problems

The vehicle interior lighting device of the present invention is characterized by comprising: a main body portion fixed to an inner surface of a roof of a vehicle on a vehicle compartment side; a first light source and a second light source housed in the main body portion; a cover portion that constitutes a frame body together with the main body portion and that covers the first light source and the second light source from below; a light guide member that has a protruding portion protruding from a gap between the main body portion and the cover portion in a direction along the inner surface, and that guides light irradiated from the first light source and the second light source to a vehicle interior; and a condensing lens disposed between the second light source and the light guide member, the light guide member including: a diffusion portion that is formed on a downward-facing surface in the protruding portion and diffuses light; and a reflection unit that reflects light emitted from the second light source and incident on the light guide member via the condenser lens toward a part of the diffusion unit, wherein the light guide member causes the diffusion unit to emit light entirely by light emitted from the first light source, and causes the diffusion unit to emit light partially by light emitted from the second light source.

Effects of the invention

The present invention relates to a vehicle interior lighting device comprising: a main body portion fixed to an inner surface of a vehicle roof on a vehicle compartment side; a first light source and a second light source housed in the main body; a cover section that forms a frame together with the main body section and covers the first light source and the second light source from below; a light guide member that has a protruding portion protruding from a gap between the main body portion and the cover portion in a direction along the inner surface, and guides light emitted from the first light source and the second light source to the vehicle interior; and a condensing lens disposed between the second light source and the light guide member.

The light guide member includes: a diffusion portion formed on a downward-facing surface of the protrusion portion and diffusing light; and a reflection unit that reflects light emitted from the second light source and incident on the light guide member via the condenser lens toward a part of the diffusion unit. The light guide member makes the diffusion portion emit light entirely by light irradiated from the first light source, and makes the diffusion portion emit light partially by light irradiated from the second light source. The vehicle interior lighting device according to the present invention is housed in a housing, and partially emits light from a diffusion portion protruding outside the housing by light from a second light source covered with a light-shielding cover portion. This provides an effect of realizing novel lighting with a floating feeling.
