Title:
LIGHTING MODULE AND ASSEMBLY METHOD THEREFOR, AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/027419
Kind Code:
A1
Abstract:
A lighting module and an assembly method therefor, and a lighting device. The lighting module comprises: a base (110), comprising a base plate (112) and a base side wall (114) disposed on the base plate (112), the base side wall (114) and the bottom plate (112) enclosing an accommodation groove (210); a light transmitting component (120), being partially disposed in the accommodation groove (210) so as to form an accommodating space (220) between the light transmitting component (120) and the base plate (112), the light transmitting component (120) comprising a light transmitting component side wall (124) which is oppositely arranged with the base side wall (114) at an interval; and a sealing component (130), being partially disposed between the light transmitting component side wall (124) and the base side wall (114), and being in close contact with the light transmitting component side wall (124) and the base side walls (114) respectively so as to seal the accommodating space (220). Thus, the lighting module can improve the illuminating brightness and the lighting efficiency. Furthermore, the lighting module does not require a compression frame and fasteners or screws to be arranged on the edge of the light transmitting component (120), thereby reducing assembling steps, improving assembly efficiency, decreasing the failure rate of products and reducing the cost.
