Document Type and Number:
WIPO Patent Application WO/2016/051895
Kind Code:
A1
Abstract:
Provided is a wavelength conversion member for efficiently forming a light distribution pattern that precisely matches a desired shape. A light emission film (1) is a wavelength conversion member including a phosphorescent substance, said film (1) having a wide surface as a top face, and having, as an ideal face, the ideal face of a side face (s), which is derived from an array of phosphor particles (P) forming the surface of the side face (s) in relation to the top face. The distance between the ideal surface and the phosphor particles (P) does not exceed the allowable value (d).
