Abstract: This invention is to provide an in-vehicle interior light unit that protects a base from a thermal damage attributable to a thermal factor and reduces cost. This is achieved by adopting a general-purpose compact bulb cassette which does not have a heat shielding function although the bulb cassette still uses a heat-resistant resin as the material thereof, and the thermal deformation due to the radiant heat from a bulb is prevented by a heat shield plate integrally formed when punch-molding a bus bar, which is formed of a conductive metal member. Thus, the radiant heat from the bulb is blocked by the heat shield plate.

Abstract: A vehicle lamp assembly includes a case, and a bulb cassette for mounting the a light bulb in the case. The case is formed of a resin material having a low thermal resistance and defines an interior space. The case includes at least one partition wall defining a planar partition wall surface to partition the interior space respectively into one and another chambers. The bulb cassette is received in an opening of the case for accommodating a light bulb within the one chamber thereof and includes at least one planar heat shield wall formed of a heat resistant resin which extends in adjacent contact along the planar partition wall surface so as to shield the at least one partition wall and the other chamber from heat generated by the light bulb in the one chamber.

Abstract: Switch-controlled vehicle room lamps are provided with an insulating structure between bus bars disposed on a back surface of a case Short circuiting between the bus bars is prevented by fitting insulating members molded from a relatively flexible resin into grooves in which the bus bars are fitted to cover exposed surfaces of the bus bars at least entirely over a portion where the mutual distance of the bus bars are reduced. In some embodiments, the insulating members are formed with projections which are adapted to be fit within holes of the case into which severed bridge portions of the bus bar extend. The projections may advantageously be provided with an acute-angled distal end and a constriction at a midsection thereof.

Abstract: A push-button switch includes a fixed member having a first fixed contact strip disposed on the inner surface of the fixed member and a second fixed contact strip disposed on the inner surface of the fixed member and opposite the first fixed contact strip; a control member biased by a spring from the fixed member and locked in a desired position; and a movable contact strip configured, when attached to the control member locked in the desired position, to be in contact with and to short-circuit the first fixed contact strip and the second fixed contact strip. The movable contact strip is configured to be isolated from the first and second fixed contact strips at substantially the same time when the control member is controlled against a biasing force of the spring.

Abstract: In the bulb cassette in the related art, a mounting fixture can be prevented from coming off a case. However, when a space in the case for accommodating a light bulb is small, there arises a problem such that a wall surface which defines the space is thermally deformed by heat from the light bulb, and hence the product value is lowered, and in the worst case, the entire case may become unusable due to thermal deformation of the wall surface. In a case in which a case formed of resin material having low thermal resistant property such as polypropylene and a wall surface which is in the proximity with a light bulb built in the case exist, a bulb cassette for mounting the light bulb in the case is formed of thermal resistant resin, and a heat shield wall interposed between the light bulb and the wall surface is formed so as to continue from the bulb cassette.
