Title:
LIGHT SOURCE MODULE AND LAMP
Document Type and Number:
WIPO Patent Application WO/2021/129664
Kind Code:
A1
Abstract:
Provided are a light source module and a lamp, comprising: a light distribution element (100) and a light source plate (200), wherein the light source plate (200) comprises a circuit board (210) and luminous bodies (220) arranged on the circuit plate (210). The light distribution element (100) is provided with a plurality of lens units (110) which are correspondingly covered on the luminous bodies (220). The lens unit (110) is recessed in a surface facing the light source plate (200) to form an accommodating cavity, a first compensation part (300) is arranged on the surface of the accommodating cavity, and the first compensation part (300) is recessed in a surface facing the light source plate (200) to form a light distribution cavity (310) for accommodating the luminous body (220). The surface of the first compensation part (300) facing the light emitting body (220) is a light incident surface (320), and the surface of the lens unit (110) deviating from the first compensation part (300) is a light emergent surface (111). The thickness of the first compensation part (300) is reduced in sequence along the direction from the geometric center of the circuit board (210) to the geometric center far away from the circuit board (210). The above-mentioned scheme can solve the problem that the current lens unit (110) is thermally deformed due to heat and affects the light distribution effect.
