The invention relates to an in-vehicle lighting device of a vehicle and a lighting control system including the in-vehicle lighting device of the vehicle. The interior lighting device of the vehicle comprises a substrate, a plurality of light sources and a light guide plate. The plurality of light sources are assembled with the substrate to be arranged in a row; the light guide plate comprises a plurality of incident parts, a diffusion area part, a view area part and a light diffusion hole; the incident parts enable light emitted by the light source to be incident on the incident parts; a diffusion region portion provided behind the incident portion to diffuse and reflect light incident on the incident portion; a field-of-view region portion provided behind the diffusion region portion to emit the light diffused and reflected by the diffusion region portion to the outside; and the light diffusion holes are arranged behind the incident parts. Specifically, each light diffusion hole is surrounded by a transmissive surface, a pair of reflective surfaces, and a diffusion surface.

    本发明涉及车辆的车内照明装置及包括车辆的车内照明装置的照明控制系统。车辆的车内照明装置包括:基板、多个光源以及导光板;所述多个光源与基板组装以布置为一排;所述导光板包括多个入射部、扩散区域部、视野区域部和光扩散孔,所述多个入射部使光源发射的光入射到多个入射部上;所述扩散区域部设置在入射部的后方,以扩散并反射入射到入射部上的光;所述视野区域部设置在扩散区域部的后方,以将由扩散区域部扩散并反射的光发射至外部;所述光扩散孔设置在各个入射部的后方。具体地,每个光扩散孔被透射面、一对反射面和扩散面包围。
