Title:
LIGHT EMITTING APPARATUS, LED ILLUMINATION APPARATUS, AND METHOD FOR MANUFACTURING PHOSPHOR-CONTAINING FILM PIECE USED IN LIGHT-EMITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/091539
Kind Code:
A1
Abstract:
Provided are: a lower-cost light-emitting apparatus having improved properties as an LED illumination device or as an LED illumination apparatus, such as an LED bulb, by eliminating interaction between the phosphors and using a structure and mechanism design for optimized conditions; and a method for manufacturing the same. The present invention is a light-emitting apparatus comprising: a semiconductor light-emitting element for emitting blue, purple, or ultraviolet light; and a phosphor for emitting intrinsic light that is excited by light from the semiconductor light-emitting element; wherein the light-emitting apparatus is characterized in having a specific structure, that is, a structure with separated phosphors, in which as the intrinsic light, two or more types of phosphors of different colors are used from among a blue phosphor for emitting blue light, a green phosphor for emitting green light, a yellow phosphor for emitting yellow light, and a red phosphor for emitting red light. The two or more types of phosphors are disposed in the lateral direction in a state in which they do not overlap each other vertically, and interactions between the phosphors are suppressed.
