Abstract
Conventionally, in order to downsize the enclosure, there was no other choice than downsizing the enclosure and decreasing the area of the lens plate, or increasing the area of the lens plate and increasing the enclosure as well. However, decreasing the area of the lens plate disadvantageously lowers brightness of illumination. In contrast to this, when the dimensions of the lens plate are increased, the proportion of the area of the lens plate with respect to the roof increases, which leads to a problem in terms of design. Accordingly, the present invention provides an interior light system for vehicles comprising a lamp accommodated in the enclosure, a push switch for turning on and off the lamp fixed in the enclosure, and a lens plate journaled at the ends of the opening of the enclosure for a swinging motion, in which the push switch is turned on and off by pressing the lens plate, thereby turning the lamp on and off.
