HERMETICALLY SEALED ILLUMINATION DEVICE WITH LUMINESCENT MATERIAL AND MANUFACTURING METHOD THEREFOR

摘要

An illumination device is manufactured by providing (101) a substrate (1) having a first side (1a), sealingly coupling (106) an at least partially light transmitting cover (2) to the substrate (1) such that an enclosed space (3) is defined by at least the first side (1a) of the substrate (1) and the cover (2), providing a through-hole (4) into the enclosed space (3), and introducing (107) a luminescent material into the enclosed space (3) via the through-hole (4). By hermetically sealing (108) the through-hole (4) after the introduction of the luminescent material, the enclosed space (3) becomes sealed and hence luminescent materials being relatively sensitive to e.g. water and/or oxygen become protected from exposure to the environment.

1. A method for manufacturing an illumination device, the method comprising:
providing a substrate having a first side provided with a light source; providing an at least partially light transmitting cover sealingly coupled to the substrate such that a chamber is defined by at least the first side of the substrate and the cover; providing a through-hole into the chamber; introducing a luminescent material into the chamber via the through-hole such that a layer of luminescent material is provided on at least a portion of an inner surface of the cover; and sealing the through-hole after the introduction of the luminescent material.
