Abstract: According to one embodiment, there is provided a vehicle interior lighting device including a plurality of light-emitting elements, a switch for switching an ON mode for lighting at least a part of the plurality of light-emitting elements and a DOOR mode for lighting at least a part of the plurality of light-emitting elements when a door of a vehicle is in an open state and extinguishing the plurality of light-emitting elements when doors of the vehicle are in a closed state, and a control section configured to control light-emitting states of the plurality of light-emitting elements to set an amount of light in the DOOR mode to be more than an amount of light in the ON mode.

Abstract: A peak of the radiation directivity of light emitted by each of LEDs is directed to a reflecting surface, and the light emitted by the LEDs is indirectly incident on an outer lens after reflection by the reflecting surface. Thus, problems, such as a local increase in brightness of a light emitting surface over areas corresponding to light emitting portions of the LEDs, are prevented. In addition, most of the light emitted by the LEDs is indirectly incident on the outer lens via the reflecting surface, so that dispersion of blue light and yellow light, which constitute the white light, by the outer lens is prevented. Thus, illumination light highly uniform in amount and color can be provided.

Abstract: A socket device according to an embodiment of the present invention includes a tubular main body 1 made of an electrically insulating material. The tubular main body 1 provides a lamp-loading hole 12 having an opening at upper end, through which a baseless lamp 6 is inserted. A notch 3 is formed in a wall of the tubular main body 1, which extends downward from the opening of the lamp-loading hole 12 along an axis of the tubular main body 1. A flange portion 2 is provided around the tubular main body 1 at a portion spaced from the lower end of the notch 3. First and second protrusions 41, 42 are provided on both sides of the notch portion 3 on the outer surface of the tubular main body 1.
