Title:
PHOSPHOR WHEEL, LIGHT SOURCE APPARATUS, AND PROJECTION TYPE DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/056285
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the heat dissipation efficiency from a phosphor wheel while suppressing air resistance and noise from the phosphor wheel when driving a light source apparatus. The phosphor wheel (100) according to the present invention is provided with: a disk-shaped substrate (120); a phosphor layer (130) formed on the substrate; and a plurality of heat dissipation fins (154a, 154b, 154c) overlapping each other when viewed in a direction perpendicular to the surface of the substrate.
