Abstract

A method and connector for connecting an electroluminescent (EL) lamp to a printed circuit board utilizing a pair of unique connector clips. Each connector clip is formed of bent sheet metal and has a bottom, a top, a closed bent end and an open end. Each connector clip is attached to a printed circuit board and the periphery of an EL lamp is positioned in the clips by sliding the EL lamp into the mouth of the connector clips. In particular, the EL lamp has a pair of contact pads on a bottom surface thereof, such that each pad contacts the bottom of a corresponding one of the connector clips. In a method of attaching the EL lamp to the printed circuit board, the EL lamp is releasably positioned in the clips by sliding the lamp into the clips. In one embodiment, positioning the EL lamp into the clips is done manually. In another embodiment, positioning the EL lamp into the clips is accomplished by a surface mount device and, particularly, by a vacuum-holding device.

Claims

1. A method of attaching an electroluminescent lamp, having at least one contact, to a printed circuit board, said method comprising:

providing a clip, said clip having a bottom and a top;

attaching said clip to said printed circuit board with a soldering step; and

sliding said electroluminescent lamp into said clip, said sliding step comprising;

providing an apparatus for releasably holding said electroluminescent lamp;

moving said holding apparatus, while holding said electroluminescent lamp so that said electroluminescent lamp slides into said clip; and

releasing said holding apparatus from said electroluminescent lamp.

2. The method as set forth in claim 1, wherein said clip has an open end defined by the outer ends of said first and second leg members, and a closed end, wherein said step of sliding comprises sliding electroluminescent lamp into said open end of said clip.

3. The method as set forth in claim 2, wherein said open end of said clip opens in a direction that is substantially parallel to a plane of said printed circuit board, wherein said sliding step comprises sliding said electroluminescent lamp in a direction that is parallel to said plane of said printed circuit board.

4. The method as set forth in claim 1, wherein said soldering step utilizes surface mount technology.

5. The method as set forth in claim 1, wherein said step of providing an apparatus for releasably holding said electroluminescent lamp comprises providing an apparatus that holds said electroluminescent lamp by a vacuum.

6. A product manufactured according to the method of claim 1.

7. A method of attaching an electroluminescent lamp to a printed circuit board, said method comprising:

soldering a clip to said printed circuit board by applying solder compound to said circuit board and vacuum-holding said clip and moving said clip into a position on said solder compound; and

connecting said electroluminescent lamp to said clip by vacuum holding said lamp and moving said lamp into said clip.

8. A product manufactured according to the method of claim 7.
