Light-emitting device of air conditioner indoor unit, air conditioner indoor unit and air conditioner

Abstract

The invention relates to an air conditioner indoor unit light-emitting device, an air conditioner indoor unit and an air conditioner, belongs to the technical field of air conditioners, and aims to solve the technical problem that light emitted by an existing air conditioner indoor unit light-emitting device is concentrated. The air conditioner indoor unit light-emitting device comprises a light source and a light guide part, the light guide part comprises an incidence area, a light guide area and a light emitting area which are sequentially arranged, diffuse reflection structures are arranged on the inner side face and / or the outer side face, facing the incidence area, of the light source, and the diffuse reflection structures are continuously distributed in the width direction of the inner side face and / or the outer side face. From the incident area to the light emitting area, the width of the light guide area increases progressively, and the distribution density of the diffuse reflection structures on the inner side face and / or the outer side face increases. The light source can be uniformly diffused, and the problem that the brightness of a light-emitting device of the air conditioner indoor unit is concentrated is effectively solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a light emitting device for an indoor unit of an air conditioner, an indoor unit and an air conditioner. Background technique [0002] With the development of society and the improvement of production technology, the functions of air conditioners are becoming more and more comprehensive, and the appearance is more beautiful. In order to facilitate users to use the air conditioner at night, the floor-standing air conditioner is equipped with a night indicator light. However, most of the lighting devices used in floor-standing air conditioners are a combination of multiple LED light sources and lampshades. This solution has the disadvantages of high cost and low reliability due to the use of multiple LED light sources. The brightness of the light-emitting device is relatively concentrated, and it is even easy to form light pollution at night. Although there are technolog...
