Abstract
Official abstract text for this publication.
A light source module includes at least one light bar, a reflector, and at least one bar-shaped reflection unit. The light bar includes light-emitting elements arranged along an extension direction. The reflector has at least one accommodation space accommodating the light bar and reflective convex surfaces located on two opposite sides of the light bar. The bar-shaped reflection unit is located above the light bar, extends along the extension direction, and has a reflection surface facing the light bar. A cross-sectional line obtained by cutting the reflection surface along an optical axis of any of the light-emitting elements and along a direction perpendicular to the extension direction includes a convex arc line protruding toward the light-emitting elements and two concave arc lines connected to two opposite sides of the convex arc line.
First claim
Opening claim text (preview).
What is claimed is: 1. A light source module comprising at least one light bar, a reflector, and at least one bar-shaped reflection unit, wherein the at least one light bar comprises a plurality of light-emitting elements arranged along an extension direction, the reflector has at least one accommodation space accommodating the at least one light bar and a plurality of reflective convex surfaces located on two opposite sides of the at least one light bar, and the at least one…
