Abstract
Official abstract text for this publication.
A light source module includes an optical unit, which includes a light-emitting device, a light-guiding device and a light-converging structure. The light-guiding device has a light incident end, a light emitting end, a first curved surface connecting the light incident end and the light emitting end, and a side surface. The light-emitting device is disposed beside the light incident end. The section of the first curved surface by the side surface is a first curve. The section of the first curved surface by the reference plane perpendicular to the side surface is a second curve. The light-converging structure is disposed between the light-emitting device and the light incident end and has a first arc-convex surface and two second convex surfaces, in which the first arc-convex surface and the second convex surfaces are arranged along a direction parallel to the side-surface.
First claim
