[0002] Surface light source refers to the mode of light emission. Compared with LED point light source and ordinary lamp light source, surface light source such as flat panel light source and LED surface light source have the characteristics of soft light, no harm to eyes, energy saving, natural light, etc. Surface light source is usually used in occasions that require large area uniform lighting.

[0003] At present, a Chinese patent with publication number CN220169410U discloses a high-protection surface light source, including a panel and a light bar. The panel is a light-guiding structure, and a light trough extending along the edge is provided on the back of the panel; the high-protection surface light source also includes a back plate and a sealant, and the edge of the back plate is provided with a side plate extending along the edge, and the back plate is arranged on the back of the panel, and the side plate extends into the light trough and divides the light trough into an inner area and an outer area, and the sealant is arranged in the outer area for sealing; the light bar is arranged in the inner area. A light trough for installing the light bar is arranged on the back of the panel, and the light bar emits light to the light-guiding area and extends the light to the front of the panel to form a surface light source. At the same time, the back plate is arranged on the back of the panel, and the back plate is used to block the light from the back and shield the light bar. Finally, a sealant is arranged in the outer area of ​​the light trough, so that the light trough can be sealed, and the light-guiding area and the light trough are sealed by the sealant and the back plate, so as to achieve the sealing of the light bar, so as to adapt to the humid working environment.

[0004] In actual use, although the existing technology protects the light bar by sealing it so that it can adapt to a humid working environment, this will also result in the light bar not being able to dissipate heat well. Excessive heat can easily affect the life and stability of the light source, resulting in poor use effect.

[0005] Therefore, the present application provides a high-protection surface light source to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a high-protection surface light source to solve the problem that the existing surface light source adopts sealing treatment to ensure the moisture-proof effect of the light bar, but affects the heat dissipation.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A high-protection surface light source comprises an aluminum alloy frame, a back plate is arranged on one side of the aluminum alloy frame, a groove is opened on the inner side of the aluminum alloy frame, and a light bar is fixed around it, a light guide plate is fixed in the middle of the aluminum alloy frame, the four sides of the light guide plate are respectively connected to the light bar, and a light source is arranged on one side of the light bar connected to the side of the light guide plate, and two layers of filter screens are arranged on the other side, a desiccant is arranged between the two layers of the filter screens, the position of the desiccant connects the light source component in the light bar with the outside of the light bar, and a heat dissipation hole connected to the filter screen is opened on the outer side of the aluminum alloy frame.

[0009] As a further preferred solution, the plurality of light strips are interconnected by cables, and a through hole is provided at one corner of the aluminum alloy frame for one of the cables to extend out.

[0010] As a further preferred solution, a power connector is fixed to one end of the cable extending outside the aluminum alloy frame.

[0011] As a further preferred solution, a diffusion plate is movably embedded in an opening on one side of the aluminum alloy frame away from the back plate, and a spring is installed between an edge of the diffusion plate and an edge of the aluminum alloy frame.

[0012] As a further preferred solution, a reflective plate is provided on the side of the back plate facing the aluminum alloy frame, and the reflective plate is in close contact with the light guide plate.

[0013] As a further preferred solution, the aluminum alloy frame is formed by aluminum die-casting, and the light source on the light bar is an SMDLED lamp bead.

[0014] As a further preferred solution, the light guide plate comprises an acrylic plate, and a silk-screen printing process is performed on the surface.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the cooperation between the aluminum alloy frame and the light bar, the heat dissipation of the light bar can be ensured by opening heat dissipation holes on the aluminum alloy frame. At the same time, two layers of filter screens are set on the side of the light bar facing the heat dissipation holes to sandwich a layer of desiccant to form dry protection, so that the device is not only suitable for humid environments, but also can ensure heat dissipation effects, which is conducive to extending service life.
