Document Type and Number:
WIPO Patent Application WO/2019/129040
Kind Code:
A1
Abstract:
Disclosed are an annular light distribution element (100), a light source module including the annular light distribution element (100), a light source component and a lighting lamp including the light source module. The annular light distribution element (100) comprises a light distribution element body (110); the light distribution element body (110) is provided with an annular accommodating space (111) and an in-light surface (112) and an out-light surface (113) being disposed at two sides of the light distribution element body (110), respectively; and the annular accommodating space (111) is used for receiving at least two lighting units (200) circumferentially distributed herein; an inner wall of the annular accommodating space (111) is an in-light surface (112); and the in-light surface (112) comprises an inner-side in-light surface (112a) close to a center of the annular light distribution element (100) and an outer-side in-light surface (112b) away from the center; a deflection angle for light projected from the lighting unit (200) deflected by a portion on the light distribution element body (110) opposite to the inner-side in-light surface (112a), is a first defecting angle (a); a deflection angle for light deflected by a portion on the light distribution element body (110) opposite to the outer-side in-light surface (112b) is a second defecting angle (b); the first defecting angle (a) is smaller than the second defecting angle (b). The solution may improve the lighting uniformity of the lighting lamp.
