| Title: |
Light-Emitting Device Employing a Reflective Light Focusing System having a Focusing Region and a Non-Focusing Region and Projection System Incorporating the Same. |
| Abstract: |
A light-emitting device and a projection system, comprising: a laser
array light source which comprises a non-light-emitting region and a
light-emitting region consisting of a plurality of laser elements; a
reflective light-condensing system which comprises a light-condensing
region and a non-light-condensing region, wherein the light-condensing
region is used for focusing and reflecting emergent light of the laser
array light source; and a light-collecting system used for collecting and
emitting the emergent light from the reflective light-condensing system.
The light-collecting system, the non-light-emitting region and the
non-light-condensing region are located in the same straight line
parallel to a light axis of the emergent light of the laser array light
source, and the light-collecting system passes through the
non-light-emitting region and/or the non-light-condensing region. The
light-emitting device and the projection system have small volumes and
can emit high-brightness and uniform faculae.
