The waterproof structure of the lamp panel of the present application is described below in conjunction with Figures 1 to 3. More specifically, the waterproof structure of the lamp panel is suitable for side-emitting clean lamps.

1 and 2 , the present application provides a waterproof structure of a lamp panel, including a frame 100 , a first waterproof sealing ring 110 , a second waterproof sealing ring 120 , a diffuse light guide composite plate 130 and a bottom plate 140 .

Specifically, the inner edge of the frame 100 is stepped and provided with a step surface, and the step surface includes a first step surface and a second step surface parallel to each other, wherein the first step surface is formed with a circle of first mounting grooves 101 for embedding and installing the first waterproof sealing ring 110, and the second step surface is formed with a circle of second mounting grooves 102 for embedding and installing the second waterproof sealing ring 120. The diffuse light guide composite plate 130 is placed in the frame 100, and the end surface of the diffuse light guide composite plate 130 Abutting against the first waterproof sealing ring 110; the chassis 140 is covered on the inner edge of the frame 100, the end surface of the chassis 140 is crimped against the second waterproof sealing ring 120, and the chassis 140 is fastened to the frame 100 by fasteners, thereby forming a sealed space in the frame.

Among them, the light source module 150 is suitable for being installed on at least one side of the frame 100 and is located in the packaging space formed between the diffuse light-guiding composite plate 130 and the chassis 140. The light source module 150 abuts against the side of the light-guiding composite plate to form a side-emitting structure, and also plays a better sealing and protective role for the light source module 150.

In actual applications, a first installation groove 101 equipped with a first waterproof sealing ring 110, a second installation groove 102 equipped with a second waterproof sealing ring 120, and a diffuse light-guiding composite plate 130 formed by a diffuser plate and a light guide plate are provided in the frame 100, and the diffuse light-guiding composite plate 130 is made to abut against the first waterproof sealing ring 110, and the chassis 140 is covered on the frame 100 and crimped with the second waterproof sealing ring 120. The waterproof structure of the lamp panel of this embodiment can not only achieve the effect of waterproof sealing and improve the safety performance of the product in harsh environments such as humidity and dust, but also use the diffuse light-guiding composite plate 130 to replace the original structure that requires both a light guide plate and a diffuser plate to be installed, thereby saving material costs, reducing assembly steps, and improving assembly efficiency.

1 and 2 , the diffuse light-guiding composite plate 130 is an integrated structure formed by combining a diffuser plate and a light guide plate through hot-melt processing. In addition, the thickness of the diffuse light-guiding composite plate 130 can be controlled within the range of 0.5 mm to 0.7 mm. In a specific embodiment, the thickness of the diffuse light-guiding composite plate 130 can be 0.6 mm, compared with the previous single-piece light guide plate with a thickness of 0.6 mm, the thickness of the single diffuser plate is 0.6 mm, and the total thickness of the light guide plate and the diffuser is 1.2 mm. This can greatly save occupied space and required materials, and before being assembled to the lamp, the diffuser plate and the light guide plate have been integrated through hot-melt processing. When assembled to the lamp, the diffuse light-guiding composite plate 130 can be directly installed, and only one installation process is required. Compared with the previous two installation processes, this saves time and improves assembly efficiency.

In this embodiment, the main material of the light guide plate can be optical grade acrylic (methacrylic The material of the diffusion plate can be polystyrene, polycarbonate, polyethylene, polypropylene, polyvinyl chloride, etc., which is not specifically limited here.

It can be understood that the light guide plate mainly plays a role of guiding light, the diffusion plate mainly plays a role of diffusing light, and the diffusion light guide composite plate 130 can play a combined role of guiding light and diffusing light.

In actual applications, if the light guide plate and the diffuser plate are assembled in a separate form, in order to maintain the rigidity of the plate, the thickness of the single plate of the diffuser plate and the light guide plate will often exceed 0.6mm, which not only consumes more materials, but also easily squeezes the installation space of other components in the clean lamp; while the diffuser plate and the light guide plate are combined into one diffuser light guide composite plate 130 through a hot melt process, while maintaining the overall rigidity of the plate in compliance with the requirements, the total thickness of the plate is greatly reduced to 0.5-0.7mm, which not only saves material costs, but also reduces assembly steps and improves assembly efficiency.

Referring to FIG. 1 and FIG. 2 , in a specific embodiment, the cross section of the frame 100 is axially symmetrical, and the axis of symmetry is a central axis perpendicular to the upper and lower end surfaces of the frame 100. Light source mounting grooves 103 are respectively provided on opposite sides of the frame 100, and the light source mounting groove 103 on one side is now described as an example: the light source mounting groove 103, the first mounting groove 101, and the second mounting groove 102 are all integrally formed on the frame 100, and the light source mounting groove 103 is located between the first mounting groove 101 and the second mounting groove 102; the first mounting groove 101 is located on the side away from the chassis 140, and the second mounting groove 102 is located on the side close to the chassis 140. In other words, the first mounting groove 101 is located close to the lower end surface of the frame 100, and the second mounting groove 102 is located close to the upper end surface of the frame 100.

In actual applications, light source mounting grooves 103 are arranged on opposite sides of the frame 100, and light source assemblies are arranged in the two light source mounting grooves 103, which can produce a more uniform lighting effect for the side-emitting clean light; on the other hand, by arranging the light source mounting groove 103 between the first mounting groove 101 and the second mounting groove 102, the first waterproof sealing ring 110 and the second waterproof sealing ring 120 can prevent water vapor or dust from entering the frame 100 from the upper and lower end surfaces of the frame 100, avoiding affecting the light source assembly, thereby forming a better waterproof sealing effect.

Referring to Figures 1 and 2, in the packaging space formed by the diffuse light-guiding composite plate 130 and the chassis 140, a reflective paper 160 and a pressing plate 170 are sequentially provided on the diffuse light-guiding composite plate 130; in a specific embodiment, the reflective paper 160 is attached to the diffuse light-guiding composite plate 130, the pressing plate 170 is located between the reflective paper 160 and the chassis 140, the pressing plate 170 is crimped onto the reflective paper 160, and the chassis 140 is crimped onto the pressing plate 170.

In practical applications, the reflective paper 160 is used to reflect the light beam emitted by the light source module 150 to the chassis 140 through the light guide plate, thereby forming a better lighting effect; the pressing plate 170 makes the diffuse light guide composite plate 130 and the reflective paper 160, and the diffuse light guide plate and the first waterproof sealing ring 110 fit more closely, which helps to improve the reflective effect of the reflective paper 160 and the waterproof sealing effect of the sealing ring.

In summary, by adopting the above technical scheme, a first waterproof sealing ring 110 is embedded in the first mounting groove 101 close to the lower end face of the frame 100, a second waterproof sealing ring 120 is embedded in the second mounting groove 102 close to the upper end face of the frame 100, and a light source assembly is installed in the light source mounting groove 103; then the diffuse light-guiding composite plate 130 is installed in the frame 100, so that the side of the diffuse light-guiding composite plate 130 abuts against the light source assembly and the end face abuts against the first waterproof sealing ring 110, and then the reflective paper 160 is attached to the diffuse light-guiding composite plate 130 and pressed with a pressing plate 170; then the chassis 140 is covered on the frame 100, so that the chassis 140 is pressed against the second waterproof sealing ring 120 and the pressing plate 170, and finally the chassis 140 and the frame 100 are fixedly connected with fasteners, thereby forming a lamp panel waterproof structure suitable for side-emitting clean lamps. The waterproof structure of the lamp panel can not only achieve the effect of waterproof sealing, improving the safety performance of the product in humid environments, but also use a hot-melt process to combine the light guide plate and the diffuser plate into one to form an integrated diffuse light guide composite plate 130 with a thickness of 0.5 to 0.7 mm, saving material costs, reducing assembly steps and improving assembly efficiency.

Referring to FIG. 2 and FIG. 3 , the present application further provides a clean waterproof lamp using the above-mentioned lamp panel waterproof structure, comprising a light source module 150 connected to a power line 180, the light source module 150 being installed on at least one side of the frame 100 and being located in the packaging space formed by the diffuse light guide composite plate 130 and the chassis 140. In a specific embodiment, the power line 180 is welded to the light source module 150. On group 150, the light source module 150 is installed on two opposite sides of the frame 100; wherein, the light source module 150 is fixed in the light source mounting groove 103 of the frame 100 by gluing, the power cord 180 passes through and extends out of the chassis 140, and the chassis 140 is fixedly connected with a wire gland 190 at the passing position of the power cord 180, and the power cord 180 is fixedly connected to the chassis 140 through the wire gland 190.

In actual application, the installation steps of the clean waterproof lamp are as follows: first assemble the first waterproof sealing ring 110 and the second waterproof sealing ring 120 on the frame 100, then install the light source module 150 on the frame 100, assemble the diffuse light-guiding composite plate 130 on the frame 100, attach the reflective paper 160 to the diffuse light-guiding composite plate 130, and crimp the pressing plate 170 on the reflective paper 160; then pass the power cord 180 through and extend it out of the chassis 140, fix the chassis 140 to the frame 100 with bolts and other fasteners, and finally fix the wire gland to the frame 100 with bolts and other fasteners, thereby completing the assembly. It should be noted that in a specific embodiment, the clean waterproof lamp adopts a rectangular frame 100, but it does not mean that the shape of the frame 100 cannot be set to other shapes such as square, circle or ellipse.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
