Zusammenfassung:	To provide a vehicle interior lighting device that can properly light up a vehicle interior.SOLUTION: A vehicle interior lighting device is configured to be installed on a ceiling in a vehicle interior. The vehicle interior lighting device comprises a power supply part, a housing, a temperature sensor, and a light emitting part. The power supply part is connected with a +B voltage wire and a ground voltage wire. The temperature sensor is installed inside the housing. The light emitting part is installed in the housing. The light emitting part can emit light with a predetermined color temperature. The light emitting part lights up the vehicle interior using electric power supplied from the power supply part. The temperature sensor detects a period lowest temperature that is lowest in a predetermined period of time. When the period lowest temperature is a first temperature, the light emitting part emits light at a first color temperature. When the period lowest temperature is a second temperature, the light emitting part emits light at a second color temperature. The second temperature is higher than the first temperature. The second color temperature is different from the first color temperature.SELECTED DRAWING: Figure 15 【課題】本開示は、室内を適切に照明できる車室内照明装置を提供する。【解決手段】本開示に係る車室内照明装置は、車両の室内の天井に設置するように設定される。車室内照明装置は、電源部と筐体と温度センサと発光部とを有する。電源部は、＋Ｂ電圧線とグランド電圧線とが接続される。温度センサは、筐体内部に設置される。発光部は、筐体に設置される。発光部は、所定の色温度で発光が可能である。発光部は、電源部から供給される電力を基に車内を照らす。温度センサにより、所定期間での最低である期間最低温度を検出する。期間最低温度が第１温度である場合、発光部は第１の色温度で発光する。期間最低温度が第２温度である場合、発光部は、第２の色温度で発光する。第２温度は、第１温度より大きい温度である。第２の色温度は、第１の色温度と異なる。【選択図】図１５
