SUBSTRATE FOR MOUNTING A PLURALITY OF LIGHT EMITTING ELEMENTS Russian patent published in 2017 - IPC H05K1/02 F21V19/02 F21V23/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to a light output device. Light output device comprises a substrate (1), having first segment (5a) for connection of first light emitting element (2a) and second segment (5b) for connection of second light emitting element (2b), wherein the substrate is provided with at least one through-hole (6a-c), that extends from 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 first segment (5a) of the substrate and the second segment (5b) of the substrate by applying a mechanical force to the substrate. Light output device additionally comprises an optical system (10) comprising first optical element (11a) for receiving light from first light emitting element (2a) and second optical element (11b) for receiving light from second light emitting element (2b), wherein each of the first and second light emitting elements are arranged to align with first and second optical elements (11a, 11b), respectively, by applying a mechanical force to said substrate.

EFFECT: invention 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.
