Substrate for mounting a plurality of light emitting elements

摘要

The present invention relates to a substrate (1) comprising: a first segment (5a) provided with a first contact pad (22a) for connection of a first light emitting element (2a); and a second segment (5b) provided with a second contact pad (22b) for connection of a second light emitting element (2b), wherein the substrate is provided with at least one through-hole (6a-c) that extends from an edge (8,9) of the substrate to a point within the substrate, such that a relative movement, in a plane of the substrate, can be achieved between the first segment (5a) of the substrate and the second segment (5b) of the substrate by applying a mechanical force to the substrate. This makes very accurate alignment to a multiple cavity optical system possible without adjusting the optics, thereby enabling a more convenient and time efficient process in production.

1. A light output device, comprising a substrate having:
a first segment provided with a first contact pad and a first light emitting element connected to the first contact pad; and a second segment provided with a second contact pad and a second light emitting element connected to the second contact pad, the substrate defining at least one through-hole that extends from an edge of said substrate to a point within said substrate, wherein said light output device further comprises an optical system comprising a first optical element for receiving light from the first light emitting element, and a second optical element for receiving light from the second light emitting element, wherein said substrate and said optical system include corresponding sets of reference elements, wherein said sets of reference elements and said at least one through-hole are positioned and structured such that application of a mechanical force through mating of said sets of reference elements induces a relative movement, in a plane of the substrate, between the first segment of the substrate and the second segment of the substrate, wherein each of the first and second light emitting elements are arranged to align with the first and second optical elements, respectively, through the application of the mechanical force.
