Description

Technical Field

[0001] The utility model relates to a panel light, in particular to a high-light-efficiency frameless panel light. Background Art

[0002] Panel lights are not only aesthetically pleasing but also provide effective lighting, making them widely used in various buildings. However, existing panel lights' light is easily blocked by the frame, reducing the panel's luminous area and, in turn, its luminous efficiency. To address this issue, many lighting manufacturers have designed frameless panel lights. However, most existing frameless panel lights utilize a narrow frame structure. This structure is achieved by shortening the frame size, but the light from the panel is still easily blocked by the frame, failing to effectively address the aforementioned issue. Some existing frameless panel lights feature side-lighting, but the structure required to achieve this is relatively complex, significantly increasing costs.

[0003] In addition, the structure of the side-lighting function will also lead to luminous flux loss, unable to achieve high luminous efficiency, and unable to effectively solve the above-mentioned problems. Utility Model Content

The housing has an opening. The light-emitting module includes a backplate and multiple light sources. The backplate is disposed within the housing through the opening. The backplate has a light outlet, and the multiple light sources are disposed within the backplate through the light outlets. The lampshade is disposed on the housing and covers the light-emitting module. The lampshade has a light inlet, which is interconnected with the light outlet. The area of the light inlet is larger than the area of the light outlet.

[0005] In one embodiment, the outer edge of the housing has a fixing channel and a fixing post. The fixing post is disposed in the fixing channel, so that the cross section of the fixing channel is U-shaped.

[0010] In one embodiment, the bottom surface of the lampshade forms the first light-emitting surface, and the side wall of the lampshade forms the second light-emitting surface.

[0011] In one embodiment, the plurality of light sources are light emitting diodes or light emitting diode arrays.

[0012] In one embodiment, the panel light further includes a power module, which is disposed in the housing.

[0013] In one embodiment, the lampshade is made of a transparent material or a translucent material.

[0014] As described above, the LED lamp according to the present invention may have one or more of the following advantages:

[0015] (1) In one embodiment of the present invention, a panel lamp includes a housing, a light-emitting module and a lampshade. The housing has an opening. The light-emitting module includes a back plate and a plurality of light sources. The back plate is arranged in the housing through the opening. The back plate has a light outlet, and the plurality of light sources are arranged in the back plate through the light outlet. The lampshade is arranged on the housing and covers the light-emitting module. The lampshade has a light inlet, and the light inlet and the light outlet are connected to each other. The area of the light inlet is larger than the area of the light outlet. Through the above-mentioned special optical structure design, the bottom surface of the lampshade can form a first light-emitting surface, and the side wall of the lampshade forms a second light-emitting surface. The first light-emitting surface can be used as a front light-emitting surface, and the second light-emitting surface can be used as a side light-emitting surface. In this way, the panel lamp not only has a front light-emitting function, but also has a side light-emitting function, so that the overall light-emitting area of the panel lamp is increased, which can greatly increase the luminous flux. Therefore, the light efficiency of the panel lamp can be effectively improved, so that the overall performance of the panel lamp is greatly improved. In addition, the panel lamp can also achieve a frameless appearance to provide a good visual effect.

[0016] (2) In one embodiment of the present invention, the panel light has a special optical structure design, which enables the panel light to have both front-facing and side-facing lighting functions.

Therefore, the panel light can truly meet the needs of energy saving and power saving.

[0017] (3) In one embodiment of the present invention, the outer edge of the housing of the panel lamp has a fixing channel and a fixing column. The fixing column is arranged in the fixing channel, so that the cross-section of the fixing channel is U-shaped. Through the structural design of the above-mentioned fixing channel, the lampshade can be arranged on the housing and fixed to the housing through a simple screwless fixing structure. Therefore, the structural complexity of the panel lamp can be greatly reduced, thereby reducing the cost of the panel lamp. At the same time, the manufacturing process of the panel lamp can also be greatly simplified, thereby reducing the manufacturing cost of the panel lamp. Therefore, the application of the panel lamp can be more extensive.

[0018] (4) In one embodiment of the present invention, the outer edge of the panel light housing has a fixing channel and a fixing post. The fixing post is disposed in the fixing channel, so that the cross-section of the fixing channel is U-shaped. Through the structural design of the fixing channel, the fixing channel can not only realize a snap-on fixing structure, but also simultaneously function as a glue groove and a glue overflow groove to realize an adhesive fixing structure. Therefore, the manufacturing process of the panel light can be more flexible to meet the needs of different applications.

[0019] (5) In one embodiment of the present invention, the outer edge of the housing of the panel lamp has a fixing channel and a fixing column. The fixing column is arranged in the fixing channel, so that the cross section of the fixing channel is U-shaped. Through the structural design of the above-mentioned fixing channel, the lampshade can be arranged on the housing and fixed to the housing by a variety of different fixing methods (such as a snap-fit fixing structure, ultrasonic welding, and adhesive fixing structure). Therefore, the user can select an appropriate fixing method according to actual needs, so that the panel lamp can better meet the needs of actual application.

[0020] (6) In one embodiment of the present invention, the panel light is simple in design, so the desired effect can be achieved while reducing costs.

For ease of understanding, identical components in the following embodiments are labeled with the same symbols.

[0034] See also Figure 1 , which is a three-dimensional diagram of a high-efficiency, borderless panel light according to the first embodiment of the present invention. As shown, the panel light 1 includes a housing 11, a light-emitting module 12, and a lampshade 13. The light-emitting module 12 is disposed within the housing 11, while the lampshade 13 is disposed on the housing 11 and covers the light-emitting module 12.

[0035] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the high-efficiency borderless panel light according to this embodiment should still be included in the patent scope of the present invention.

[0036] See also Figure 2 and Figure 3 . Figure 2This is a first schematic diagram of a high-light-efficiency borderless panel light according to the first embodiment of the present invention. Figure 3 This is a second schematic diagram of the high light efficiency borderless panel light of the first embodiment of the utility model. Figure 2 As shown, the housing 11 has an opening PN. First, the user can place the light emitting module 12 in the housing 11 through the opening PN, and then fix the light emitting module 12 in the housing 11 through a plurality of fixing members Fx.

[0037] like Figure 3 As shown, the user can then place the lampshade 13 on the housing 11 and fix it to the housing 11 so that the lampshade 13 covers the light emitting module 12 .

[0038] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the high-efficiency borderless panel light according to this embodiment should still be included in the patent scope of the present invention.

[0039] See also Figure 4 , which is a cross-sectional view of the high light efficiency frameless panel light of the first embodiment of the present invention; and please also refer to Figure 1 、 Figure 2 and Figure 3 As shown in the figure, the light-emitting module 12 includes a backplate 121 and a plurality of light sources 122. The backplate 121 is disposed within the housing 11 through an opening PN. The backplate 121 has a light outlet L1 (an area indicated by a dotted chain line in the figure), and the plurality of light sources 122 are disposed within the backplate 121 through the light outlet L1. In this embodiment, the plurality of light sources 122 may be light-emitting diodes (LEDs). In another embodiment, the plurality of light sources 122 may be an LED array.

[0040] The lampshade 13 has a light inlet L2 (the area indicated by the two-dot chain line in the figure), and the light inlet L2 is connected to the light outlet L1. The area of the light inlet L2 is larger than the area of the light outlet L1, so that an optical extension space ES is formed between the periphery of the lampshade 13 and the bottom of the housing 11 (as shown in FIG. Figure 5 and Figure 7 In one embodiment, the lampshade 13 is made of a transparent material or a translucent material. In this embodiment, the lampshade 13 can be made of plastic. In another embodiment, the lampshade 13 can be made of glass.

[0041] The panel light 1 also includes a power module 14. The power module 14 is disposed within the housing 11. In this embodiment, the power module 14 may be a power supply. In another embodiment, the power module 14 may be a battery or other similar component. As can be seen above, because the area of the light inlet L2 of the lampshade 13 is larger than the area of the light outlet L2 of the backplate 121, the light generated by the multiple light sources 122 passes through the light outlet L2 and enters the light inlet L2 of the lampshade 13, where it then diffuses to the front and sides of the lampshade 13.

[0042] Through the above-mentioned special optical structure design, an optical extension space ES is formed between the periphery of the lampshade 13 and the bottom of the housing 11, so the bottom surface of the lampshade 13 can form a first light-emitting surface S1, and the side wall of the lampshade 13 forms a second light-emitting surface S2 (such as Figure 1 As shown in the figure, the first light-emitting surface S1 (the bottom surface of the lampshade 13) can serve as the front light-emitting surface, while the second light-emitting surface S2 (the side wall of the lampshade 13) can serve as the side light-emitting surface. This allows the panel light 1 to not only emit light from the front but also from the side, increasing the overall light-emitting area and significantly boosting the luminous flux. Consequently, the luminous efficiency of the panel light 1 can be effectively improved, significantly enhancing its overall performance. Furthermore, the panel light 1 can achieve a frameless appearance, providing a superior visual effect.

[0043] Furthermore, in this embodiment, the panel light 1 features a unique optical design, enabling it to emit light from both the front and side. This significantly improves the light efficiency of the panel light 1, saving energy and reducing carbon emissions. Therefore, the panel light 1 truly meets energy and power conservation requirements.

[0044] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the high-efficiency borderless panel light according to this embodiment should still be included in the patent scope of the present invention.

[0045] See also Figure 5 , which is a partial enlarged view of the high light efficiency borderless panel light of the first embodiment of the present utility model; please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 . Figure 5 for Figure 4 As shown in the figure, the outer edge of the housing 11 has a fixing channel FC and a fixing post FP.

[0046] The fixing post FP is disposed in the fixing channel FC, so that the cross section of the fixing channel FC is U-shaped.

[0047] The inner wall of the lamp housing 13 has a plurality of protrusions 131 .

[0048] The multiple protrusions 131 are embedded in the fixing channel FC and interlock with the fixing post FP. The fixing channel FC, fixing post FP, and the multiple protrusions 131 form a screwless fixing structure. Thanks to the structural design of the fixing channel, the lampshade 13 can be mounted on the housing 11 and secured to it using a simple screwless fixing mechanism. Consequently, the structural complexity of the panel light 1 can be significantly reduced, lowering its cost. Furthermore, the manufacturing process of the panel light 1 can be significantly simplified, reducing its manufacturing cost. Consequently, the panel light 1 can be applied in a wider range of applications.

[0049] Furthermore, the outer edge of the housing 11 of the panel light 1 may also include a fixing channel and fixing posts. The fixing posts are positioned within the fixing channel, giving the fixing channel a U-shaped cross-section. This fixing channel design allows the lampshade 13 to be attached to and secured to the housing 11 using a simple, screwless fixing mechanism. Consequently, the structural complexity of the panel light 1 can be significantly reduced, lowering its cost. Furthermore, the manufacturing process can be significantly simplified, reducing its manufacturing cost. This allows for a wider range of panel light applications. The fixing channel not only enables a snap-fit fixing structure but also serves as a glue injection and overflow groove for adhesive fixing. This provides greater flexibility in the manufacturing process of the panel light to meet diverse application requirements. The lampshade 13 can be attached to and secured to the housing 11 using a variety of fixing methods, such as snap-fit fixing, ultrasonic welding, and adhesive fixing. Therefore, users can choose the appropriate fixing method based on their actual needs, allowing the panel light 1 to better meet their application requirements.

[0050] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the high-efficiency borderless panel light according to this embodiment should still be included in the patent scope of the present invention.

[0051] It's worth noting that existing panel lights are easily blocked by their bezels, reducing their luminous area and, consequently, their luminous efficiency. To address this issue, many lighting manufacturers have designed borderless panel lights. However, most existing borderless panel lights employ a narrow bezel. While this structure is achieved by shortening the bezel, the light from the panel lights is still easily blocked by the bezel, failing to effectively address the aforementioned issue. Some existing borderless panel lights feature side-lighting, but the structure required to implement this feature is complex, significantly increasing costs. Furthermore, this side-lighting feature also results in luminous flux loss, preventing high luminous efficiency and effectively addressing the aforementioned issue. In contrast, according to an embodiment of the present invention, a panel light comprises a housing, a light-emitting module, and a lampshade. The housing has an opening. The light-emitting module includes a backplate and multiple light sources. The backplate is disposed within the housing through the opening. The backplate has a light outlet, and the multiple light sources are disposed within the backplate through the light outlet. The lampshade is disposed on the housing and covers the light-emitting module. The lampshade has a light inlet, which is interconnected with the light outlet. The area of the light inlet is larger than the area of the light outlet. Through the above-mentioned special optical structure design, the bottom surface of the lampshade can form a first light-emitting surface, while the side walls of the lampshade can form a second light-emitting surface. The first light-emitting surface can serve as the front light-emitting surface, while the second light-emitting surface can serve as the side light-emitting surface. In this way, the panel light not only has front light-emitting function but also side light-emitting function, which increases the overall light-emitting area of the panel light and significantly increases the luminous flux. Therefore, the luminous efficiency of the panel light can be effectively improved, significantly enhancing the overall performance of the panel light. In addition, the panel light can also achieve a frameless appearance, providing a good visual effect. According to the embodiments of the utility model, the panel light has a special optical structure design, which not only has front light-emitting function but also side light-emitting function. Therefore, the luminous efficiency of the panel light can be effectively improved, allowing the panel light to save energy loss and reduce carbon emissions. Therefore, the panel light can truly meet the needs of energy saving and power saving.

[0052] Furthermore, according to an embodiment of the present invention, the outer edge of the panel light housing has a fixing channel and fixing posts. The fixing posts are disposed within the fixing channel, giving the fixing channel a U-shaped cross-section. This structural design of the fixing channel allows the lampshade to be attached to the housing and secured to the housing using a simple, screwless fixing mechanism. Consequently, the structural complexity of the panel light can be significantly reduced, thereby lowering its cost. Furthermore, the manufacturing process can be significantly simplified, reducing its manufacturing cost. Consequently, the panel light can be applied in a wider range of applications.

[0053] Furthermore, according to an embodiment of the present invention, the outer edge of the panel light housing has a fixing channel and fixing posts. The fixing posts are disposed within the fixing channel, giving the fixing channel a U-shaped cross-section. This structural design of the fixing channel not only enables a snap-on fixing structure but also functions as a glue injection and overflow channel for adhesive fixation. This allows for greater flexibility in the manufacturing process of the panel light to meet the needs of diverse applications.

[0054] Furthermore, according to embodiments of the present invention, the outer edge of the panel light housing has a fixing channel and fixing posts. The fixing posts are positioned within the fixing channel, giving the fixing channel a U-shaped cross-section. This structural design of the fixing channel allows the lampshade to be attached to and secured to the housing using a variety of different fixing methods, such as snap-fit fixing, ultrasonic welding, and adhesive fixing. Therefore, users can choose the appropriate fixing method based on their actual needs, allowing the panel light to better meet their application requirements.

[0055] Furthermore, according to the embodiments of the present invention, the panel light has a simple design, thus achieving the desired effect while reducing costs. Consequently, the practicality of the panel light can be greatly improved and it can meet future development trends. As can be seen from the above, the high-efficiency frameless panel light according to the embodiments of the present invention can indeed achieve excellent technical results.

[0056] See also Figure 6 , which is a first partial enlarged view of the high light efficiency borderless panel light of the second embodiment of the utility model; and please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 . Figure 6 FIG2 is an enlarged view of area A2 of the lampshade 13. As shown in the figure, all four sides of the lampshade 13 have arcs (rounded corners). Unlike the previous embodiment, the lampshade 13 does not have the aforementioned multiple protrusions 131.

[0057] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the high-efficiency borderless panel light according to this embodiment should still be included in the patent scope of the present invention.

[0058] See also Figure 7 , which is a second partial enlarged view of the high light efficiency borderless panel light of the second embodiment of the utility model; please also refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 . Figure 7 for Figure 4An enlarged view of area A1 of FIG. 1 (however, the structure of the lampshade 13 of this embodiment is different from that of the previous embodiment).

[0059] The portion of the fixing channel FC to the right of the fixing post FP serves as a glue groove K1, while the portion to the left of the fixing post FP serves as an overflow groove K2. Thus, the fixing channel FC functions as both the glue groove K1 and the overflow groove K2. The user can fill the glue groove K1 of the fixing channel FC with adhesive and then insert the outer edge of the lampshade 13 into the glue groove K1 of the fixing channel FC. This secures the outer edge of the lampshade 13 to the glue groove K1 of the fixing channel FC. Excess adhesive is then pushed into the overflow groove K2 and prevented from overflowing from the fixing channel FC.

[0060] In another embodiment, the outer edge of the lampshade 13 may also be directly fixed in the fixing channel FC by ultrasonic welding (or other similar fixing methods).

[0061] As can be seen above, the outer edge of the housing 11 of the panel light 1 has a fixing channel FC and fixing posts FP. The fixing posts FP are positioned within the fixing channel FC, giving the fixing channel FC a U-shaped cross-section. This structural design of the fixing channel FC not only enables a snap-on fixing mechanism but also functions as a glue groove K1 and a glue overflow groove K2 for adhesive fixing. This allows for greater manufacturing flexibility in the panel light 1 to meet the needs of diverse applications.

[0062] Furthermore, according to an embodiment of the present invention, the outer edge of the housing 11 of the panel light 1 has a fixing channel FC and fixing posts FP. The fixing posts FP are disposed within the fixing channel FC, giving the fixing channel FC a U-shaped cross-section. Due to the structural design of the fixing channel FC, the lampshade 13 can be attached to and secured to the housing 11 using a variety of different fixing methods (such as snap-fit fixing, ultrasonic welding, and adhesive fixing). Therefore, users can select the appropriate fixing method based on their actual needs, allowing the panel light 1 to better meet practical application requirements.

[0063] Similarly, the panel light 1 of this embodiment also features a unique optical design. This optical structure allows the bottom surface of the lampshade 13 to form a first light-emitting surface S1, while the sidewalls of the lampshade 13 form a second light-emitting surface S2. The first light-emitting surface S1 serves as the front light-emitting surface, while the second light-emitting surface S2 serves as the side light-emitting surface. This allows the panel light 1 to illuminate not only the front light but also the side light, increasing its overall light-emitting area and significantly boosting its luminous flux. Consequently, the panel light 1's luminous efficiency is significantly enhanced, significantly improving its overall performance. Furthermore, the panel light 1 achieves a frameless appearance, providing a superior visual experience.

[0064] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the high-efficiency borderless panel light according to this embodiment should still be included in the patent scope of the present invention.

[0065] See also Figure 8 and Figure 9 . Figure 8 This is a three-dimensional diagram of a high-light-efficiency borderless panel light according to the third embodiment of the present invention. Figure 9 This is a cross-sectional view of a high-efficiency, frameless panel light according to the third embodiment of the present invention. As shown, the panel light 1 comprises a housing 11, a light-emitting module 12, and a lampshade 13. The light-emitting module 12 is disposed within the housing 11, while the lampshade 13 is disposed on the housing 11 and covers the light-emitting module 12.

[0066] Unlike the previous embodiment, the panel light 1 is circular. That is, the housing 11 and the lampshade 13 are also circular. The shape of the panel light 1 can be designed according to actual needs and is not limited to the shape of the above embodiment.

[0067] The light-emitting module 12 includes a backplate 121 and a plurality of light sources 122. The backplate 121 is disposed within the housing 11. The backplate 121 has a light outlet L1 (indicated by the dotted chain line in the figure), and the plurality of light sources 122 are disposed within the backplate 121 through the light outlet L1. In this embodiment, the plurality of light sources 122 may be light-emitting diodes (LEDs). In another embodiment, the plurality of light sources 122 may be an LED array.

[0068] The lampshade 13 has a light inlet L2 (the area indicated by the two-dot chain line in the figure), and the light inlet L2 is connected to the light outlet L1. The area of the light inlet L2 is larger than the area of the light outlet L1, so that an optical extension space ES is formed between the periphery of the lampshade 13 and the bottom of the housing 11 (as shown in FIG. Figure 5 and Figure 7 In one embodiment, the lampshade 13 is made of a transparent material or a translucent material. In this embodiment, the lampshade 13 can be made of plastic. In another embodiment, the lampshade 13 can be made of glass.

[0069] The panel light 1 also includes a power module 14. The power module 14 is disposed within the housing 11. In this embodiment, the power module 14 may be a power supply. In another embodiment, the power module 14 may be a battery or other similar component. Similarly, because the area of the light inlet L2 of the lampshade 13 is larger than the area of the light outlet L2 of the backplate 121, the light generated by the multiple light sources 122 passes through the light outlet L2 and enters the light inlet L2 of the lampshade 13, where it then diffuses to the front and sides of the lampshade 13.

[0070] Through the above-mentioned special optical structure design, an optical extension space ES is formed between the periphery of the lampshade 13 and the bottom of the housing 11, so the bottom surface of the lampshade 13 can form a first light-emitting surface S1, and the side wall of the lampshade 13 forms a second light-emitting surface S2 (such as Figure 8 As shown in the figure, the first light-emitting surface S1 (the bottom surface of the lampshade 13) can serve as the front light-emitting surface, while the second light-emitting surface S2 (the side wall of the lampshade 13) can serve as the side light-emitting surface. This allows the panel light 1 to not only emit light from the front but also from the side, increasing the overall light-emitting area and significantly boosting the luminous flux. Consequently, the luminous efficiency of the panel light 1 can be effectively improved, significantly enhancing its overall performance. Furthermore, the panel light 1 can achieve a frameless appearance, providing a superior visual effect.

[0071] Furthermore, in this embodiment, the panel light 1 features a unique optical design, enabling it to emit light from both the front and side. This significantly improves the light efficiency of the panel light 1, saving energy and reducing carbon emissions. Therefore, the panel light 1 truly meets energy and power conservation requirements.

[0072] As can be seen above, the panel light 1 of this embodiment is circular. This embodiment also has a rectangular shape (as shown in the previous embodiment). The shape of the panel light 1 can be designed based on actual needs; for example, the panel light 1 can also be polygonal (such as a pentagon, hexagon, etc.), and is not limited to the shape of the above embodiment. Panel lights 1 of different shapes can all adopt the above optical structure design to achieve the same effect.

[0073] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the high-efficiency borderless panel light according to this embodiment should still be included in the patent scope of the present invention.

[0074] In summary, according to an embodiment of the present invention, a panel light comprises a housing, a light-emitting module, and a lampshade. The housing has an opening. The light-emitting module comprises a backplate and multiple light sources. The backplate is disposed within the housing through the opening. The backplate has a light outlet, and the multiple light sources are disposed within the backplate through the light outlet. The lampshade is disposed on the housing and covers the light-emitting module. The lampshade has a light inlet, which is interconnected with the light outlet. The area of the light inlet is larger than the area of the light outlet. Due to the aforementioned unique optical structural design, the bottom surface of the lampshade forms a first light-emitting surface, while the side walls of the lampshade form a second light-emitting surface. The first light-emitting surface can serve as the front light-emitting surface, while the second light-emitting surface can serve as the side light-emitting surface. This allows the panel light to have both front and side light-emitting functions, increasing its overall light-emitting area and significantly boosting its luminous flux. Consequently, the panel light's luminous efficiency is significantly improved, significantly enhancing its overall performance. Furthermore, the panel light can achieve a frameless appearance, providing a superior visual effect.

[0075] According to the embodiments of the present invention, the panel light features a unique optical design, enabling it to illuminate both the front and side surfaces. This significantly improves the light efficiency of the panel light, saving energy and reducing carbon emissions. Consequently, the panel light truly meets energy and power conservation requirements.

[0076] Furthermore, according to an embodiment of the present invention, the outer edge of the panel light housing has a fixing channel and fixing posts. The fixing posts are disposed within the fixing channel, giving the fixing channel a U-shaped cross-section. This structural design of the fixing channel allows the lampshade to be attached to the housing and secured to the housing using a simple, screwless fixing mechanism. Consequently, the structural complexity of the panel light can be significantly reduced, thereby lowering its cost. Furthermore, the manufacturing process can be significantly simplified, reducing its manufacturing cost. Consequently, the panel light can be applied in a wider range of applications.

[0077] Furthermore, according to an embodiment of the present invention, the outer edge of the panel light housing has a fixing channel and fixing posts. The fixing posts are disposed within the fixing channel, giving the fixing channel a U-shaped cross-section. This structural design of the fixing channel not only enables a snap-on fixing structure but also functions as a glue injection and overflow channel for adhesive fixation. This allows for greater flexibility in the manufacturing process of the panel light to meet the needs of diverse applications.

[0078] Furthermore, according to embodiments of the present invention, the outer edge of the panel light housing has a fixing channel and fixing posts. The fixing posts are positioned within the fixing channel, giving the fixing channel a U-shaped cross-section. This structural design of the fixing channel allows the lampshade to be attached to and secured to the housing using a variety of different fixing methods, such as snap-fit fixing, ultrasonic welding, and adhesive fixing. Therefore, users can choose the appropriate fixing method based on their actual needs, allowing the panel light to better meet their application requirements.

[0079] Furthermore, according to the embodiments of the present invention, the panel light has a simple design, thus achieving the desired effect while reducing costs. Therefore, the practicality of the panel light can be greatly improved and can meet future development trends.

[0080] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model.
