Title:
SUBSTRATE FOR LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, AND METHOD FOR PRODUCING SUBSTRATE FOR LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/014853
Kind Code:
A1
Abstract:
Provided is a substrate for a light-emitting element, with which it is possible to realize broad directivity of the luminous intensity distribution of emitted light and also to prevent degradation of a frame filled with resin as a result of exposure to the emitted light. Also provided are a light-emitting device and a method for producing the substrate for a light-emitting element. A substrate (1) for a light-emitting element comprises: a substrate main body (2) which has a mounting surface (21a) for mounting a light-emitting element (11), and which is formed from a sintered compact of a glass ceramic composition including 30 to 50 mass% of glass powder and 50 to 70 mass% of ceramic filler; and a frame (8) which is disposed at the mounting surface (21a) side of the substrate main body (2) so as to enclose the light-emitting element (11) mounted on the mounting surface (21a), and which includes 80 mass% or more of a glass that is transparent to visible light emitted from the light-emitting element (11).
