Title:
PROJECTOR
Document Type and Number:
WIPO Patent Application WO/2018/030632
Kind Code:
A1
Abstract:
A projector is provided. The projector includes: a fluorescent wheel; at least one first light source that emits light toward the fluorescent wheel; and a fly eye lens that uniformalizes light, having transmitted the fluorescent wheel. Therefore, a fly eye lens is used instead of a light tunnel and a transmissive fluorescent wheel is used and thus it is unnecessary to divide a lens configuration of transmitting light and reflecting light. Accordingly, the number of optical systems can be reduced and thus efficiency of a projector can be enhanced and a size and production cost of the projector can be reduced.
