Document Type and Number:
WIPO Patent Application WO/2020/135290
Kind Code:
A1
Abstract:
A light source (10) comprises: a first light-guiding member (100) having a first light-entering end surface (110) and a first light output member (120) respectively arranged at two end portions thereof; a second light-guiding member (200) having a second light-entering end surface (210) and a second light output member (220) respectively arranged at two end portions thereof; a first light source (300), a first light beam emitted therefrom entering the first light-guiding member (100) via the first light-entering end surface (110) and exiting via the first light output member (120) to form illumination light; and a second light source (400), a second light beam emitted therefrom entering the second light-guiding member (200) via the second light-entering end surface (210) and exiting via the second light output member (220) to form illumination light, wherein the first light output member (120) and the second light output member (220) are arranged opposite to and close to each other, and orthographic projections of the first light output member (120) and the second light output member (220) on a plane perpendicular to a central axis of the first light output member (120) or the second light output member (220) at least partially overlap. The light source (10) has favorable heat dissipation performance and a high brightness level.
