The invention provides a vehicle interior lighting device which is low in luminosity attenuation and can be configured at low cost. A vehicle interior lighting device is provided with a light source (610) and a translucent cover (300), and the cover (300) is provided with: a light incident part (310) on which illumination light emitted from the light source (610) is irradiated; and a reflection part (320) which is formed on a surface opposite to the vehicle interior side and reflects the illumination light entering the cover (300) toward the vehicle interior side, the light entering part (310) having: a light transmitting part (311) through which a part of the illumination light emitted from the light source (610) passes toward the vehicle interior side, and a light receiving part (312) through which a part of the illumination light emitted from the light source (610) passes toward the vehicle interior side; and an incidence unit (312) that causes a part of the illumination light emitted from the light source (610) to enter the interior of the cover (300).
本发明提供一种光度的衰减少的能廉价地构成的车辆内室照明装置。车辆内室照明装置具备光源(610)和透光性的罩(300),在罩(300)设有:入光部(310),被照射从光源(610)发出的照明光;以及反射部(320),形成于与车辆内室侧相反侧的面,使入光至罩(300)内的照明光向车辆内室侧反射,入光部(310)具有:透光部(311),使从光源(610)发出的照明光的一部分向车辆内室侧通过;以及入射部(312),使从光源(610)发出的照明光的一部分向罩(300)的内部入光。
