Document Type and Number:
WIPO Patent Application WO/2022/266801
Kind Code:
A1
Abstract:
A ceiling lamp, comprising a ceiling lamp main body (1). The ceiling lamp main body (1) comprises a lamp housing (11) and a diffusion plate (12); a horizontally arranged light guide plate (2) is mounted in a cavity that is enclosed by the lamp housing (11) and the diffusion plate (12); and an illumination light source lamp strip (3) and an ambient light source lamp strip (4) are further mounted in the cavity, wherein the ambient light source lamp strip (3) is located in the back direction of the light guide plate (2); and a light reflecting layer (5) is arranged on the back side of the light guide plate (2), and the outer diameter of the light reflecting layer (5) is slightly less than the outer diameter of the light guide plate (2), such that a circle of a light-transmitting area (21) that is not covered by the light reflecting layer (5) is formed on the light guide plate (2), and ambient light rays generated by the ambient light source lamp strip (4) are configured to be transmitted onto the light-transmitting area (21) of the light guide plate (2) by means of propagation. After passing through the light guide plate (2) and the diffusion plate (12), illumination light rays emitted by the illumination light source lamp strip (3) can radiate downwards to form an illumination light effect, and the ambient light rays generated by the ambient light source lamp strip (4) can be transmitted onto the light-transmitting area (21) of the light guide plate (2) by means of propagation, thereby generating an ambient light ring at the periphery of the diffusion plate (12) that can be more aesthetic.
