Refrigerator and total-reflection honeycomb backlight LED illuminating lamp thereof

Abstract

The invention discloses a total-reflection honeycomb backlight LED illuminating lamp of a refrigerator and the refrigerator using the illuminating lamp. The illuminating lamp comprises a plurality of surface mounted LED lamps arranged on the front surface of a lamp panel, light emitting surfaces of the LED lamps cling to one side of a light guide plate, reflective paper is pasted on the other three sides of the light guide plate, a honeycomb engraved groove is engraved on one surface of the light guide plate, a reflective plate is arranged on the side of the light guide plate with the engraved groove, the lamp panel, the light guide plate and a reflective plate are connected onto a refrigerator clamp, and a closed cavity is formed between the light guide plate and the reflective plate. The illuminating lamp has the advantages of safety, low power consumption, low heating value, large light emitting surfaces, and soft and uniform light, has no extremely dense area, and can bring fresh and bright use experience for users in both daytime and nighttime.

Description

Technical field: [0001] The invention relates to a total reflection honeycomb backlight LED lighting lamp for a refrigerator and a refrigerator equipped with the lighting lamp. Background technique: [0002] At present, incandescent lamps or point-shaped LED lights are mostly used for lighting in refrigerators, and the point light sources are diverged with lampshades. However, due to the problem of luminous color, heat generation and space constraints, it is impossible to perfectly convert the point light source into a surface light source, and the visual quality is not in harmony with the overall configuration of the refrigerator. There are only a few solutions on the market that install LEDs behind the floodlight panel with low light transmittance Due to the large space occupied and poor practicability, high-end refrigerators urgently need a surface light source lighting system with low power consumption, low heat generation, high brightness, and low space occupation to pa...

However, due to the problem of luminous color, heat generation and space constraints, it is impossible to perfectly convert the point light source into a surface light source, and the visual quality is not in harmony with the overall configuration of the refrigerator. There are only a few solutions on the market that install LEDs behind the floodlight panel with low light transmittance Due to the large space occupied and poor practicability, high-end refrigerators urgently need a surface light source lighting system with low power consumption, low heat generation, high brightness, and low space occupation to pair with it
