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 light source housed in the main body portion; a cover section that constitutes a frame together with the main body section and that covers the light source from below; and 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 irradiated from the light source to a vehicle interior, the light guide member including: a diffusion portion that is formed on a downward-facing surface of the protrusion portion and diffuses light; a first light guide unit that guides light emitted from the light source to the protruding portion; and a reflection unit configured to reflect the light guided by the first light guide unit toward the diffusion unit.

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 light source housed in the main body; a light-shielding cover portion which constitutes a frame body together with the main body portion and covers the light source from below; and 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 irradiated from the light source to the vehicle interior.

The light guide member includes: a diffusion portion formed on a downward-facing surface of the protrusion portion and diffusing light; a first light guide unit that guides light emitted from the light source to the protruding portion; and a reflection unit that reflects the light guided by the first light guide unit toward the diffusion unit. The vehicle interior lighting device according to the present invention is housed in a housing, and a diffusion portion protruding to the outside of the housing is caused to emit light by light of a light source covered with a light-shielding cover portion. This has the effect of realizing novel illumination with a floating feeling.
