Title:
CEILING LAMP
Document Type and Number:
WIPO Patent Application WO/2018/000990
Kind Code:
A1
Abstract:
A ceiling lamp, comprising: a chassis (100); a light-emitting assembly (200) disposed on the chassis (100), further comprising: a diffusion structural member (300a) disposed outside the light-emitting assembly (200) and configured to uniformly diffuse the light emitted by the light-emitting assembly (200); and a light-transmitting structural member (400) disposed outside the diffusion structural member (300a), wherein a micro-prism structure (430) is disposed on the light-transmitting structural member (400) and configured to make the light uniformly diffused by the diffusion structural member (300a) form a pattern corresponding to the micro-prism structure (430) on the light-transmitting structural member (400). The diffusion structural member (300a) functions to make the light uniform, so that the light passing through the diffusion structural member (300a) is uniformly diffused and so that a large range of unevenness between light and dark is avoided. The micro-prism structure (430) disposed on the light-transmitting structural member (400) changes the running direction of the light, so to as enable the light to form the pattern corresponding to the micro-prism structure (430) on the light-transmitting structural member (400) after passing through the light-transmitting structural member (400), and so as to enable the pattern to have more texture than a pattern directly coated onto the surface of the light-transmitting structural member (400).
