Luminous laminar flow ceiling

Abstract

The invention discloses a light-emitting laminar flow air supply ceiling. The light-emitting laminar flow air supply ceiling comprises a light-permeable flow equalization mesh plate, a box and a light source. The box comprises side plates on the four faces and a top plate on the top, and the side plates are communicated with an air inlet. The light-permeable flow equalization mesh plate is located on the bottom surface of the box. The light source is located in the box. A reflecting layer is arranged on the inner surface of the top plate. The light source comprises strip-shaped side light sources arranged along the inner walls of the side plates, and the light-emitting surfaces of the side light sources face upwards and project light onto the reflecting layer. According to the light-emitting laminar flow air supply ceiling, based on the light reflection principle, reflected light is generated under the reflecting action of the reflecting layer and projected onto the light-permeable flow equalization mesh plate, a large part of the reflected light permeates through the light-permeable flow equalization mesh plate and forms lighting light, and the lighting light illuminates an operating table or the surrounding area of the operating table; thus, the light is soft, the brightness is appropriate, a patient can not see a lamp in the ceiling, and the indirect lighting method is beneficial for operation of medical workers and elimination of the feeling of tension and repression brought by an original dark and dull air supply ceiling to the patient.

Description

Technical field [0001] The invention relates to a luminous laminar flow air supply ceiling for a clean operating room. Background technique [0002] The function of the laminar air supply ceiling in the clean operating room is to provide laminar flow for the operating table and the surrounding area, rather than turbulent clean air flow, which can completely control the operating area in a clean atmosphere and minimize air during the operation Infection with bacteria-carrying particles. The current clean laminar flow air supply ceiling has only air supply function and no built-in lighting. The indoor lighting of the operating room is realized by the light strips arranged around the air supply ceiling. This lighting method creates a dark area in the center of the operating table. During the operation, the patient faces the dark air supply ceiling, which is prone to feel tension and depression. The Chinese patent ZL201120002469.0 discloses "A luminous laminar flow ceiling for clea...

AI Technical Summary

Problems solved by technology

The indoor lighting of the operating room is realized by the light strips arranged around the air-supply ceiling. This lighting method forms a dark area in the center of the operating table. During the operation, the patient faces the dark air-supply ceiling and is prone to feel nervous and depressed.

Chinese patent ZL201120002469.0 discloses "A Luminous Laminar Flow Ceiling for Clean Operating Room". A lighting lamp is installed in the middle of the ceiling. Although the lighting function is provided, the lamp tube can be seen directly. Using the principle of direct lighting, the light is not soft and dazzling

There is also a light-emitting ceiling that adopts the principle of light guide, such as "A Large-area Light-emitting Ceiling" disclosed in Chinese patent ZL201220301653. The way of light input is difficult to maintain, the structure is heavy, and the light will attenuate inside the light guide plate, and the light guide plate used in the clean operating room will need a very large area, which is expensive, heavy, and inconvenient to install
