Claims9
A device for mounting a cartridge lamp having one or more electrical leads, said mounting device comprising:
- a substantially hollow lead housing having opposite ends with a first opening at one end for receiving a lead or leads from the cartridge lamp and a second opening at the other end;
- said housing having a base member with a lower protrusion at the second opening of the lead housing for engaging a surface of a circuit board;
- and
- said housing having an upper protrusion in opposing relation to said lower protrusion of said lead housing, whereby an electrical lead may be bent over said upper protrusion for securing the cartridge lamp to the mounting device.
A light source for mounting on a circuit board, comprising:
- a cartridge lamp having at least on electrical lead at each end thereof;
- a substantially hollow lead housing arranged over each of said leads from the cartridge lamp;
- each of said lead housings including:
- a first opening at a first end for receiving one of the leads from one end of said cartridge lamp;
- a second opening at a second end of said housing opposite said first end of said housing for exposing said one lead for connection with said circuit board;
- a lower protrusion from a lower portion of the second end of the lead housing for engaging a surface of the circuit board;
- and
- an upper protrusion overhanging said second opening of said lead housing, said at least one electrical lead being bendable over said upper protrusion for securing the cartridge lamp to the mounting device.
A method of mounting a cartridge lamp in a socket on a circuit board, said cartridge lamp having an electrical lead extending from each of two opposite ends of the lamp, said method comprising the steps of:
- inserting each of said leads through respective lead housings, each of said lead housings being substantially hollow and having an opening at each end, each of said lead housings having an upper protrusion overhanging one of said openings, said upper protrusion including a central portion for engaging the circuit board;
- securing said respective lead housings to each end of said cartridge lamp by bending respective leads over said upper protrusions from the respective lead housings;
- aligning the central portions of said secured lead housings with respective slots at each end of the socket in said circuit board;
- sliding the upper portion of said respective lead housings into said socket.
