Official abstract text for this publication.
A vehicle indoor illumination device includes a housing having an upper opening with an internal space formed therein, a light-emitting unit disposed on the housing to emit light, a diffuser disposed outside the light-emitting unit in a manner as to close the upper opening of the housing to allow the light emitted from the light-emitting unit to diffuse to the outside, a cover part disposed on an outer surface of the diffuser and on which a light pattern is formed through scattering of the light transmitted through the diffuser, and a controller configured to receive an operation signal of a vehicle electronic part to control an operation of the light-emitting unit.
Opening claim text (preview).
What is claimed is: 1. A vehicle indoor illumination device, comprising: a housing having an upper opening with an internal space formed therein; a light-emitting unit disposed on the housing to emit light; a diffuser disposed outside the light-emitting unit and configured to enclose the upper opening of the housing and allow the light emitted from the light-emitting unit to diffuse outside of the housing; a cover part disposed on an outer surface of the diffuser and on which a light pattern is formed through scattering of the light transmitted through the diffuser; and a controller configured to receive an operation signal to control an operation of the light-emitting unit, wherein the housing is a dashboard or an instrument panel. 2. The vehicle indoor illumination device according to claim 1 , wherein the light-emitting unit comprises: a substrate within the housing; and a plurality of light-emitting elements surface-mounted on the substrate. 3. The vehicle indoor illumination device according to claim 2 , wherein each of the light-emitting elements is an RGB LED. 4. The vehicle indoor illumination device according to claim 1 , wherein the light-emitting unit and the diffuser are spaced apart from each other. 5. The vehicle indoor illumination device according to claim 1 , wherein the cover part is attached to the outer surface of the diffuser. 6. The vehicle indoor illumination device according to claim 5 , wherein the cover part is provided with a pattern portion in which a predetermined pattern is formed. 7. The vehicle indoor illumination device according to claim 1 , wherein the internal space comprises: a first spatial portion disposed on one side in the housing; and a second spatial portion disposed on the opposite side of the first spatial portion of the housing.
