Abstract
A battery-operated automatically switched lighting device is provided for illumination of the interior of enclosures provided with doors, such as for closets, cupboards, cabinets, and the like. Identical light transmitting housing parts are assembled together to contain batteries, a light bulb, and formed metal strips acting as contacts and switch actuator when the enclosure door is opened and closed. Various protrusions projecting from the bottom wall of each housing part together form battery, bulb, housing, and contact strip locating features, and molded locking tabs snap fit together to releasably hold the housing parts together.
Claims11
A battery-powered lighting device comprising:
- a housing formed by two housing part, at least one housing part being translucent, each housing part having a bottom wall and a rim extending about said bottom wall perimeter, said housing parts positioned facing each other with said rim in abutment to form an enclosed space;
- locking means holding said housing parts together;
- a pair of elongated batteries in said housing enclosed space, each battery having a terminal at either end thereof;
- a pattern of battery guide protrusions extending between an inside of said bottom wall of each of said housing parts, said protrusions locating said pair of elongated batteries side-by-side;
- a bulb seat protrusion projecting from an inside of each housing part bottom wall towards each other;
- said bulb seat protrusions each including a seating feature;
- a bulb held between said seating features of said bulb seat protrusions, with a base contact thereof held against a terminal of a first one of said batteries at one end thereof;
- a first contact strip of electrically conductive material held against an adjacent respective terminal at an opposite end of each of said batteries;
- a second contact strip of electrically conductive material extending from a terminal at one end of a second of said batteries to a rim contact on said bulb to complete a battery circuit to said bulb to energize said bulb;
- said second contact strip having a section extending out of said housing with a switch actuator portion able to be contacted by a movable structure;
- said second contact strap also having a resiliently deflectable portion deflected by inward movement of said switch actuator portion and causing said second contact strip to move out of contact with said terminal at said one end of said second battery, to thereby disconnect said battery circuit.
