Problems solved by technology

Surface light sources are also prone to water ingress in refrigerator residual frost and frost blocking experiments
[0007] C) After the top light-emitting LED is irradiated, the edge of the acrylic material and the double-sided tape will produce light-gathering effect and light reflection, forming an obvious halo on the edge, which will affect the visual effect. It is necessary to use a frame of at least 6mm or more for shading treatment, which will affect the appearance

Abstract

The invention discloses a refrigerator area light source and a manufacturing process thereof, and relates to the technical field of refrigerator area light sources. The refrigerator area light source comprises a refrigeration fan cover, an area light source assembly, a function display assembly and a function display decoration plate. The area light source assembly comprises a glass light guide substrate, a mirror reflection film, an LED patch lamp fixing strip and an LED patch lamp. The glass light guide substrate adopts sodium-calcium ultra-white glass. The back face of the glass light guide substrate is printed on the attaching face through light guide ink. The mirror reflection film is fully attached to the attaching face of the glass light guide substrate through optical cement. The area light source assembly is installed on the function display decoration plate in a matched manner and assembled on the front face of the refrigeration fan cover. The defect that an acrylic area light source light guide plate is prone to deformation is solved, high strength is achieved, and deformation is not prone to happening; and meanwhile, aluminum alloy frames needed by the two sides of an original conventional acrylic area light source can be omitted, the frameless appearance of the acrylic area light source is achieved, and the cost can be simplified and reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigerator surface light sources, and in particular relates to a refrigerator surface light source and a manufacturing process thereof. Background technique [0002] At present, it has become a development trend to use large-area surface light sources on the back of high-end refrigerators and refrigerators for lighting. The conventional method is to use large-scale acrylic light-guiding surface light sources. Acrylic light guide plate combined with PS diffuser plate and reflector to realize surface light source lighting, its material characteristics and specific multi-level structure have the following limitations: [0003] a) The main materials of "acrylic surface light source": acrylic light guide plate, PS diffuser and reflector. These materials have high expansion coefficients and are easily deformed when they are cold or heated, causing deformation of the surface light source components. It needs ...
