Title:
LUMINESCENT ELEMENT MODULE
Document Type and Number:
WIPO Patent Application WO/2008/018336
Kind Code:
A1
Abstract:
A luminescent element module (40) which comprises a base (1), a luminescent element (LED
bare chip (20)) disposed thereon, and a first encapsulant (31) and a second encapsulant
(32) which have been superposed in this order on the element. In order to prevent
reflection at the interface (33) between the first encapsulant (31) and the second
encapsulant (32) and thereby improve the efficiency of light extraction from
the luminescent element, the interface (33) between a first encapsulating resin
material (31o) and a second encapsulating resin material (32o) is made gradational
before the first encapsulating resin material (31o) and the second encapsulating
resin material (32o) are completely cured.
