Title:
OPTICAL ELEMENT AND LIGHT DISTRIBUTION MODULE
Document Type and Number:
WIPO Patent Application WO/2020/199944
Kind Code:
A1
Abstract:
The present application discloses an optical element and a light distribution module, the optical element comprising: an optical element body provided with a light-entering surface and with a light-exiting surface, the optical element body having provided thereon a second reflective surface disposed circumferentially along the light-exiting surface; the second reflective surface and the light-exiting surface forming a hollow cavity, and a light source being disposed in the hollow cavity; the light-entering surface being adhered to a top portion of the light source; along a diameter direction of the light-exiting surface, a surface of the light-exiting surface comprising a first transparent surface, a matte surface and a second transparent surface, successively connected. A light distribution module comprising: an optical element and the aforementioned reflector; along a direction from a light-exiting opening to a light-entering opening, one end of the optical element being connected to the light-entering opening. The present application discloses an optical element, and providing a portion of a light-exiting surface of the optical element as a matte surface, so that the optical element and a reflector may form a clear cut-off line, thus enhancing lateral-surface light spot uniformity, enhancing central light intensity, and enhancing front-surface light spot uniformity.
