Abstract

Light emitting diodes are mounted in an assembly of electrical leads and lenses, the leads having a common carrier strip attached thereto and pairs of resilient contact fingers, the diodes being resiliently gripped between pairs of contact fingers and then encapsulated in a light transmitting material which itself forms a diffusing lens; a separate lens alternatively being provided by a rigid outer shell of light transmitting material.

Claims

1. A diode mounting assembly, comprising:

first and second conductive carrier strips, each having a projecting series of electrically conducting contacts bent outwardly of the plane of a respective carrier strip, with portions of the series of said contacts overlapping corresponding portions of the series of said contacts on the other carrier strip to define cooperating pairs of resilient gripping fingers adapted for engaging and gripping opposite sides of miniature electronic circuit devices, and

with said devices being supported by cooperating pairs of said fingers in positions outwardly of the plane of each said carrier strip and in alignment with clearance spaces defined between said carrier strip and between cooperating pairs of said fingers, so that said devices are exposed for access thereto from directions across the plane of each said carrier strips.

2. The structure as recited in claim 1, wherein, said carrier strips are interconnected by metal strip portions having web portions connected to cooperating pairs of said fingers, said web portions having openings therethrough in alignment with said clearance spaces.

3. The structure as recited in claim 2, wherein, said webs include pairs of depending electrical lead portions.

4. The structure as recited in claim 1, wherein, said carrier strips are adjustable with respect to each other to adjust the overlapped portions of said cooperating pairs of said contacts, either in compression with each other or spaced apart with small clearances, to accommodate gripping of said devices.

5. The structure as recited in claim 4, wherein, said contacts tend to return resiliently toward the plane of a corresponding said carrier strip after being bent, providing a resilient spring action biasing said overlapping portions of cooperating pairs of said contacts toward each other.

6. The structure as recited in claim 1, wherein, said contacts tend to return resiliently toward the plane of a corresponding said carrier strip after being bent, providing a resilient spring action biasing said overlapping portions of cooperating pairs of said contacts toward each other.
