Abstract
A heat-sensitive variable-resistance insert device for use with a light bulb and socket including: a thin, heat-sensitive variable-resistance wafer and a perimetrical insulation member surrounding the edge of the wafer and electrically insulating it from the wall of the socket. The wafer has a contact area on one side for engaging the central contact of the socket and on the other side thereof for engaging the central contact of the light bulb, and an adhesive paste on that other side within the perimetrical member for adhering the device to the base of a light bulb.
Claims21
A heat-sensitive variable-resistance insert device for use with a light bulb and socket comprising:
- a heat-sensitive variable-resistance wafer;
- a perimetrical ceramic insulation member surrounding the edge of said wafer and electrically insulating it from the wall of the socket;
- said wafer having a contact area on one side for engaging the central contact of the socket and on the other side for engaging the central contact of the light bulb;
- and
- an adhesive paste on said other side of said wafer within said perimetrical member for adhering the device to the base of a light bulb.
A heat-sensitive variable-resistance insert device for use with a light bulb and socket comprising:
- a heat-sensitive variable-resistance wafer;
- a perimetrical insulation member surrounding the edge of said wafer and electrically insulating it from the wall of the socket:
- said wafer having a contact area on one side for engaging the central contact of the socket and on the other side for engaging the central contact of the light bulb;
- and
- an adhesive paste on said other side of said wafer within said perimetrical member for adhering the device to the base of a light bulb, said adhesive paste being a two-part catalytically activated adhesive with the two parts mounted adjacent each other on said wafer.
A heat-sensitive variable-resistance insert device for use with a light bulb and socket comprising:
- a heat-sensitive variable-resistance wafer;
- a perimetrical insulation member surrounding the edge of said wafer and electrically insulating it from the wall of the socket, said insulation member including a plurality of resilient elements on at least one side thereof for cushioning said insulation member against the socket base;
- said wafer having a contact area on one side for engaging the central contact of the socket and on the other side for engaging the central contact of the light bulb;
- and
- an adhesive paste on said other side of said wafer within said perimetrical member for adhering the device to the base of a light bulb.
