[0032] Panel lights are currently widely used in daily life and industrial settings. They offer excellent lighting effects, emitting uniform, planar light with an aesthetically pleasing quality. Existing panel lights typically utilize two lighting methods: direct-down lighting and side-lit lighting.

[0033] The panel lights in the related art have technical problems such as insufficient light output angle and the need to improve the overall lighting effect.

[0034] Please refer to Figure 1-Figure 4 This embodiment provides a light-emitting panel lamp, which can effectively improve the above-mentioned technical problems, increase the light output angle, and thus improve the overall lighting effect of the lamp.

[0035] In this embodiment, the light panel lamp is used to be installed on the ceiling of a house and used as a ceiling lamp. In other embodiments, the light panel lamp can also be installed on a wall side wall or other position, which is not specifically limited here.

[0036] In this embodiment, the light emitting panel lamp is mainly used for lighting in indoor scenes such as offices, homes, shopping malls or hotels.

[0037] The luminous panel light includes a light guide plate 10 and a light emitter 20. The light guide plate 10 has a mounting groove 101 therein. The light emitter 20 is used to emit light. The light emitter 20 is disposed in the mounting groove 101. The light emitted by the light emitter 20 is used to diffuse outward through the light guide plate 10.

[0038] The mounting groove 101 is located in the middle of the light guide plate 10 , and the mounting groove 101 is communicated with the side surface of the light guide plate 10 .

[0039] Specifically, the light guide plate 10 used in this embodiment has a square structure. The light guide plate 10 is arranged parallel to the ceiling. The side of the light guide plate 10 closest to the ceiling is defined as the top surface, and the side away from the ceiling is defined as the bottom surface. The mounting groove 101 is provided on the top surface of the light guide plate 10 and extends through the top surface of the light guide plate 10.

[0040] It should be noted that panel lights in the prior art generally adopt two methods: direct lighting and side lighting. Regardless of whether direct lighting or side lighting is adopted, the luminous angle of panel lights in the prior art is mostly between 110° and 120°. The overall lighting effect needs to be improved. In order to solve this technical problem, the luminous panel light provided in this embodiment is provided with a mounting groove 101 inside the light guide plate 10 when in use. The light-emitting body 20 is installed inside the mounting groove 101. After the light-emitting body 20 emits light, the light can diffuse outward from the inside of the light guide plate 10. Since the light guide plate 10 is arranged outside the light-emitting body 20, the light guide plate 10 is placed externally so that the entire light guide plate 10 serves as a light guide. The light can be diffused upward, downward, and in all directions through the light guide plate 10, thereby increasing the light output angle, achieving a large-area diffusion of light outward, and improving the overall lighting effect.

[0041] The light emitting panel lamp provided in this embodiment can achieve a light emitting angle of 360°, which is much larger than the light emitting angle of the panel lamp in the prior art, thereby greatly improving the lighting effect.

[0042] It should also be noted that the light guide plate 10 in this embodiment is exposed outside the light source 20, allowing it to function as a heat sink. Due to its large surface area, the light guide plate 10 helps dissipate heat more quickly, extending the lifespan of the lamp. Furthermore, the exposed light guide plate 10 in this light panel lamp reduces light loss during propagation, allowing more effective light to reach the illuminated area, thereby improving the overall lighting efficiency and brightness of the light panel lamp.

[0043] In this embodiment, the light guide plate 10 is made of an acrylic plate. In other embodiments, the light guide plate 10 can also be made of a PC plate. This is not specifically limited here.

[0044] It should also be noted that at least one surface of the light guide plate 10 is provided with a light-distributing structure. Specifically, the light-distributing structure is provided on both the top and bottom surfaces of the light guide plate 10. This light-distributing structure increases the heat dissipation area of ​​the light guide plate 10, thereby increasing the overall service life of the lamp. In other embodiments, the light-distributing structure may be provided only on the top surface of the light guide plate 10, only on the bottom surface of the light guide plate 10, only on the side surfaces of the light guide plate 10, or on all of the top, bottom, and side surfaces of the light guide plate 10, without specific limitation herein.

[0045] In this embodiment, the light-uniform structure is a frosted surface. The surface of the light guide plate 10 is set to a frosted surface. Due to the presence of several particles on the frosted surface, the surface of the light guide plate 10 is rough, which can diffusely reflect, scatter, and refract light to achieve uniform illumination, reduce glare, and make the light softer and more transparent.

[0046] In other embodiments, the light-homogenizing structure may also be a curved surface, specifically a wavy curved surface, which is not specifically limited here.

[0047] In this embodiment, the light-emitting body 20 includes a light strip 21 and a driver 22. The driver 22 is connected to the light strip 21. The light strip 21 is installed in the installation groove 101. The light strip 21 is used to emit light under the drive of the driver 22. The emitted light is used to diffuse outward through the light guide plate 10.

[0048] In this embodiment, the light strip 21 is an annular structure, and the shape of the mounting groove 101 is adapted to the shape of the light strip 21. The light strip 21 is an LED light strip, which is arranged along the circumference of the mounting groove 101, and the lamp beads of the LED light strip are in contact with the circumferential side walls of the mounting groove 101.

[0049] Specifically, the driver 22 includes a power supply and a circuit board. The power supply and the circuit board are connected, and the electrodes of the LED light strip are connected to the circuit board.

[0050] In this embodiment, the light panel lamp further includes a housing 30, which is connected to the light guide plate 10 and covers the mounting groove 101. The housing 30 includes an upper cover 31 and a back plate 32, which are respectively disposed on either side of the light guide plate 10 and are both detachably connected to the light guide plate 10. The upper cover 31 covers the mounting groove 101.

[0051] Specifically, the upper cover 31 and back panel 32 cover either side of the through hole 102 in the center of the light guide plate 10, thereby sealing the through hole 102 and the mounting slot 101. The side of the upper cover 31 facing away from the light guide plate 10 is used to connect to the ceiling, thereby securing the entire light panel light to the ceiling. The back panel 32 covers the bottom surface of the light guide plate 10, and the driver 22 is mounted on the back panel 32.

[0052] It should also be noted that a through hole 102 is passed through the middle of the light guide plate 10 . The through hole 102 is located inside the mounting groove 101 . The driver 22 is disposed in the through hole 102 . The through hole 102 is used to accommodate the driver 22 .

[0053] In this embodiment, the upper cover 31 and the back plate 32 are both circular structures, and the diameters of the upper cover 31 and the back plate 32 are both larger than the diameter of the mounting groove 101 .

[0054] In addition, a connecting portion 11 is provided in the middle of the light guide plate 10 . The connecting portion 11 is located inside the mounting groove 101 . The upper cover 31 and the back plate 32 are both detachably connected to the connecting portion 11 .

[0055] Specifically, the connecting part 11 is located between the through hole 102 and the mounting groove 101, and a plurality of connecting holes 110 are provided on the connecting part 11. When the upper cover 31 and the back plate 32 respectively cover the top surface and the back surface of the light guide plate 10, bolts are passed through the connecting holes 110 to detachably connect the upper cover 31, the light guide plate 10 and the back plate 32.

[0056] In this embodiment, the number of the connection holes 110 is six. In other embodiments, the number of the connection holes 110 may be increased or decreased, which is not specifically limited here.

[0057] The advantages of the luminous panel lamp provided by the embodiment of the utility model include at least:

[0058] Panel lights in the prior art generally adopt two types of lighting: direct-down lighting and side-lighting lighting. Regardless of whether direct-down lighting or side-lighting lighting is adopted, the luminous angle of panel lights in the prior art is mostly between 110° and 120°. The overall lighting effect needs to be improved. In order to solve this technical problem, the luminous panel light provided in this embodiment is provided with a mounting groove 101 inside the light guide plate 10 when in use, and the light-emitting body 20 is installed inside the mounting groove 101. After the light-emitting body 20 emits light, the light can diffuse outward from the inside of the light guide plate 10. Since the light guide plate 10 is arranged outside the light-emitting body 20, the light guide plate 10 is placed externally so that the entire light guide plate 10 serves as a light guide. The light can be diffused upward, downward, and in all directions through the light guide plate 10, thereby increasing the light output angle, achieving a large-area diffusion of light outward, and improving the overall lighting effect.

[0059] The luminous panel lamp provided in this embodiment includes a housing 30, a light guide plate 10 and a light-emitting body 20. The overall structure is simple, which simplifies the overall structure of the lamp, thereby reducing the assembly steps of the lamp and the production cost of the lamp.

[0060] The light guide plate 10 of the illuminated panel light provided in this embodiment is exposed outside the light source 20, allowing the light guide plate 10 itself to function as a heat dissipation mechanism. Due to its large surface area, the light guide plate 10 helps dissipate heat more quickly, extending the lifespan of the lamp. Furthermore, the direct exposure of the light guide plate 10 reduces light loss during propagation, allowing more effective light to reach the illuminated area, thereby improving the overall luminous efficiency and brightness of the illuminated panel light.

[0061] In summary, the embodiment of the present invention provides a light-emitting panel lamp, which includes a light guide plate 10 and a light-emitting body 20. The light guide plate 10 has a mounting groove 101 provided therein. The light-emitting body 20 is used to emit light. The light-emitting body 20 is disposed within the mounting groove 101. The light emitted by the light-emitting body 20 is used to diffuse outward through the light guide plate 10. During use, the light guide plate 10 has a mounting groove 101 provided therein. The light-emitting body 20 is mounted within the mounting groove 101. After the light-emitting body 20 emits light, the light can diffuse outward from the interior of the light guide plate 10. Since the light guide plate 10 is disposed outside the light-emitting body 20, the external placement of the light guide plate 10 allows the entire light guide plate 10 to serve as a light guide. The light can diffuse upward, downward, and in all directions through the light guide plate 10, thereby increasing the light output angle, achieving a large-area diffusion of light outward, and improving the overall lighting effect.

[0062] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model.
