Abstract

Two substantially identical LED modules each have a nonconductive base having a straight edge and a pair of faces, at least one LED on the base, and two conductive traces on the base connected to the LED and forming on one of the faces inner and outer contacts spaced along a line perpendicular from the edge with the outer contact between the inner contact and the edge. The modules are juxtaposed at the edges with the lines aligned with each other and the one faces generally coplanar. A clip has a nonconductive body bearing on the one faces of both of the bases at the edges and two respective conductors on the clip body having portions spaced apart along the aligned lines and bearing on the contacts of both bases. The clip body and conductors are pressed against the bases to engage the conductors with the respective contacts and secure the bases together.

Claims

1. An assembly comprising:

two substantially identical LED modules each having

a nonconductive base having a straight edge and a pair of faces,

at least one LED on the base, and

two conductive traces on the base connected to the LED and forming on one of the faces inner and outer contacts spaced along a line perpendicular from the edge with the outer contact between the inner contact and the edge, the modules being juxtaposed at the edges with the lines aligned with each other and the one faces generally coplanar; and

a clip having

a nonconductive body bearing on the one faces of both of the bases at the edges,

two respective conductors on the body having conductive portions spaced apart along the aligned lines and bearing on the contacts of both bases, and

means for pressing the body and conductors against the bases and engaging the conductors with the respective contacts.

2. The assembly defined in claim 1 wherein the contacts extend through the respective bases and are exposed on both faces thereof.

3. The assembly defined in claim 1 wherein the modules are each formed at predetermined spacings from the respective edges with seats open toward the clip body, the clip body being formed with respective centering pins engaged in the seats.

4. The assembly defined in claim 3 wherein the clip body has a pair of elastically deflectable arms carrying the centering pins.

5. The assembly defined in claim 3 wherein the pins and seats lie on the line.

6. The assembly defined in claim 5 wherein both of the seats are spaced identically from the respective edges.

7. The assembly defined in claim 1 wherein each of the conductors has one end fixed to the clip body and an opposite end forming the conductive portions engageable with the respective contacts.

8. The assembly defined in claim 7 wherein each of the conductors is thin and elastically deformable.

9. The assembly defined in claim 7 wherein the opposite ends are formed as a pair of arms forming the respective conductive portions.

10. The assembly defined in claim 7 wherein the base is formed with a pair of mounting pins and the one ends of the conductors are formed with lips elastically gripping the respective mounting pins.

11. The assembly defined in claim 1 wherein the means is a cover fixed to the clip body and bearing on the other faces of both of the bases at the edges.

12. The assembly defined in claim 11 wherein the cover has at least one barb arm extending through and clipping it to the base.
