LIGHT GUIDE ELEMENT AND LAMP
Document Type and Number:
WIPO Patent Application WO/2023/088034
Kind Code:
A1
Abstract:
A light guide element (40) and a lamp (400). The light guide element (40) is used to guide light emitted from a light source (20), and the light guide element (40) is provided with a light-incident portion (41) and a light guide portion (42), wherein the light source (20) is disposed below the light-incident portion (41); the side of the light-incident portion (41) that is close to the light source (20) is recessed to form a light-incident surface (A), the light-incident surface (A) being a curved surface; and the light guide portion (42) is provided with a light-exit surface, and the light guide portion (42) is arranged beside the light-incident portion (41) and is connected to the light-incident surface (A), so that the light emitted from the light source (20) passes through the light-incident surface (A) and then enters the light guide portion (42) and propagates inside the light guide portion (42), with the light inside the light guide portion (42) being emitted through the light-exit surface in the propagation path thereof. By means of the light source in a direct-lit arrangement, in cooperation with the light-incident portion (41) on the light guide element (40), the light guide element (40) can achieve side-emitting of light, which not only realizes an ultra-thin shape of the lamp (100), but also increases the creepage distance of the light source, thereby improving the luminous efficiency of the lamp (100) and the natural softness of the light.
