The present invention relates to an interior lighting device of a vehicle and a lighting control system including the same. The interior lighting device comprises: a substrate; a plurality of light sources assembled on the substrate and arranged in a row; and a light guide plate. The light guide plate includes: a plurality of incident portions into which a light emitted from the light sources is incident; a diffusion area provided behind the incident portions and in which the light incident through the incident portions is diffused and reflected; a viewing area provided behind the diffusion area and in which the light irradiated through the diffusion area is radiated to the outside; and a light diffusion hole provided behind each of the incident portions and surrounded by the transmission surface, a pair of reflection surfaces, and the diffusion surface. At this time, the transmission surface is formed on each of the incident portions so as to face each of the light sources and configured to transmit some of the light emitted from the light sources. The diffusion surface is configured to diffuse the light which has passed through the light diffusion hole by transmitting the transmission surface to the viewing area. Each of the above reflective surfaces is configured to reflect some of the light irradiated from the light source to the outside of the light diffusion hole and irradiate the same to the viewing area.

    본 발명은 차량의 실내 조명 장치 및 이를 포함한 조명 제어 시스템에 관한 것이다. 상기 실내 조명 장치는: 기판과; 상기 기판에 조립되어 일렬로 배열된 복수의 광원들; 및 상기 광원들로부터 방출되는 빛이 입사되는 복수의 입사부들과, 상기 입사부들의 후방에 구비되어 상기 입사부들을 통해 입사된 빛이 확산되고 반사되는 확산영역부, 상기 확산영역부의 후방에 구비되어 상기 확산영역부를 통해 조사된 빛을 외부로 방출하는 시계영역부, 및 상기 각 입사부의 후방에 구비되어 투과면과 한 쌍의 반사면 및 확산면으로 둘러싸인 광확산홀을 구비하는 도광판을 포함한다. 이때, 상기 투과면은 상기 각 광원을 마주하도록 상기 각 입사부에 형성되어 광원에서 방출되는 빛 중 일부를 투과시키도록 구성되고, 상기 확산면은 상기 투과면을 투과하여 상기 광확산홀을 통과한 빛을 시계영역부로 확산시키도록 구성되고, 상기 각 반사면은 상기 광원으로부터 조사되는 빛 중 일부를 상기 광확산홀의 외부로 반사시켜 상기 시계영역부로 조사하도록 구성된 것을 특징으로 한다.
