Description

Technical Field

[0001] This utility model belongs to the field of surface light source technology, and specifically relates to a surface light source with built-in sterilization effect. Background Technology

[0002] A surface light source refers to a light emission pattern. Compared to LED point light sources and ordinary lamp light sources, existing surface light sources, such as flat panel light sources and LED surface light sources, have characteristics such as soft light emission, eye-friendly light, energy saving, and natural light. Most lamps using surface light sources provide only a single lighting function. However, with the development of modern society, single lighting function can no longer meet people's diverse needs. For example, in hospitals or some places in life, ultraviolet (UV) lamps are added for sterilization to kill bacteria in the air and reduce the health impact caused by airborne bacteria. Furthermore, because UV lamps cannot directly irradiate people (as they can cause skin and eye damage), they cannot be used in areas where people frequently visit. This also means that commonly used lighting fixtures cannot incorporate UV lamp structures to provide effective sterilization functions.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surface light source with built-in sterilization effect, thereby solving the problems mentioned in the background technology.

Each set of air inlet and air outlet slots has a dustproof component installed at the end away from the center of the light source cover assembly. The outer periphery of the upper surface of the light source cover assembly has a sterilization cavity for improving the sterilization path of the introduced indoor air. The sterilization cavity is a spiral structure and an ultraviolet sterilization strip is installed inside it. A sealing plug is installed above the upper starting point of the ultraviolet sterilization strip. The lower surface of the light source cover assembly has a light source cavity. A light source bottom cover is provided below the light source cover assembly. An ultraviolet sterilization lamp for auxiliary sterilization is provided in the light source bottom cover.

[0006] In a preferred embodiment, a mapping lamp is provided around the light source cavity, and a surface light source body is provided inside the light source cavity and surrounding the mapping lamp. Above the surface light source body is a lamp group controller for controlling the mapping lamp, the surface light source body and the ultraviolet germicidal lamp, which is an independent control structure. When a person is present, the ultraviolet germicidal lamp is turned off, and when no person is present, the ultraviolet germicidal lamp is turned on to assist in sterilization.

[0007] In a preferred embodiment, the light source cover is further provided with a light-diffusing plate, and a limiting groove is also provided at the beginning of the sterilization chamber on the upper surface of the light source cover assembly. A limiting plate is provided in the ultraviolet sterilization strip, and the limiting plate and the limiting groove are interlocked.

[0008] In a preferred embodiment, a sterilization strip body is fixedly connected below the limiting plate. The sterilization strip body is a soft strip structure. The sterilization strip body is introduced along the sterilization cavity of the spiral structure, so that the sterilization strip body is introduced through the starting end of the sterilization cavity and is introduced sequentially. The limiting plate and the limiting groove are interlocked, so that the sterilization strip body sterilizes the introduced air.

[0009] In a preferred embodiment, a first air guide groove is provided above the three sets of air inlet grooves and at the beginning of the sterilization chamber, and a second air guide groove is provided below the three sets of air outlet grooves and at the end of the sterilization chamber.

[0012] In a preferred embodiment, a light guide plate is provided above the inner circumference of the ultraviolet germicidal lamp, and a diffuser plate is provided below the light guide plate.

[0013] In a preferred embodiment, a set of mounting slots is provided on the outer side of the end of the air inlet slot and the air outlet slot away from the center of the light source cover assembly. The dustproof component is provided with a mounting frame, and a dustproof net is provided on the inner side of the mounting frame.

Outside air is introduced through the air guide fan in the air inlet slot, flows into the sterilization chamber, and is then discharged to the outside through the air outlet slot. The ultraviolet sterilization strip installed in the sterilization chamber sterilizes the introduced air. The sealing plug completes the sealing of the sterilization chamber and assists in the installation of the ultraviolet sterilization strip. When no one is present, the ultraviolet sterilization lamp is turned on to directly irradiate the area below, providing auxiliary sterilization. Thus, the sterilization function can be provided.

[0016] By adding a light source cover assembly and a dustproof component, the dustproof component is installed in the air inlet and outlet slots, and the mounting frame is fitted into the mounting slot and connected with screws, thereby reducing the entry of dust and making it easy to install and remove the dustproof component.

[0036] The sterilization chamber 105 has a spiral structure and an ultraviolet sterilization strip 300 is installed inside it. A sealing plug 400 is installed above the upper starting point of the ultraviolet sterilization strip 300. A light source cavity is opened on the lower surface of the light source cover assembly 100. A light source bottom cover 200 is provided below the light source cover assembly 100.

Above the surface light source body 108 is a lamp group controller for controlling the mapping lamp 109, the surface light source body 108 and the ultraviolet germicidal lamp 203. The controller is an independent control structure. When a person is present, it controls the ultraviolet germicidal lamp 203 to turn off, and when no person is present, it controls the ultraviolet germicidal lamp 203 to start auxiliary sterilization.

[0038] The light source base cover 200 is also provided with a light uniform plate 201. The sterilization chamber 105 is located on the upper surface of the light source outer cover assembly 100 and a limiting groove 106 is also provided.

The sterilization chamber 105 has a spiral structure that can extend the air delivery path. The sterilization strip body 302 installed inside the chamber is sterilized. Then the sterilized air is discharged to the outside through the air outlet groove.

[0045] Secondly, when there are no people in the area where the light source is used, the ultraviolet germicidal lamp 203 is activated and the light is evenly transmitted to each area through the internal optical structure via the light guide plate 204. After the light is emitted from the light guide plate 204, it is further diffused by the diffuser plate 205 to achieve auxiliary irradiation of the light, thereby providing the sterilization function.
