In this embodiment, the light-emitting panel comprises a heat dissipation aluminum plate 6, a light guide plate 7 and a diffusion plate 8. In addition, in this embodiment, the power driver 5 comprises a shell, and a power source or a driver is arranged in the shell.

[0041] Figure 2 is a front view schematic diagram of the LED panel lamp of the present invention, Figure 3 is a schematic diagram of the back side of the LED panel lamp of the present invention, Figure 1 The LED panel luminaire shown is an exploded schematic diagram from bottom to top.

[0042] See also Figure 4The mounting bracket 3 has an annular frame, which includes an inner annular mounting plate 31 and an outer annular clamping groove 32 arranged along the periphery of the inner annular mounting plate 31 , and a clamping member 33 is arranged in the outer annular clamping groove 32 .

[0043] See also Figure 5 The lamp body 1 is provided with an inner annular support plate 11 for carrying the inner annular mounting plate 31 and an outer annular fixing member 12 arranged around the inner annular support plate 11. The outer annular fixing member 12 has a card slot 13. The card 33 of the outer annular card slot 32 is inserted into the card slot 13 of the outer annular fixing member 12 and rotated to realize a rotational connection between the mounting bracket 3 and the lamp body 1. The present invention realizes a snap-fit ​​fixed rotational connection between the mounting bracket 3 and the lamp body 1 through the card 33 and the card slot 13 structure. This structure is easier to install and disassemble, and the mounting bracket 3 is universal, and users can realize simple replacement.

[0044] In this embodiment, in order to facilitate plugging and manufacturing, a clamping arm 14 is provided at a position corresponding to the clamping slot 13 on the outer annular fixing member 12, and the clamping arm 14 is arranged parallel to the inner annular support plate 11, and the gap formed between the clamping arm 14 and the inner annular support plate 11 forms a guide groove for the clamping member 33 to enter the clamping slot 13. The clamping slot 13 of the outer annular fixing member 12 is directly formed by a groove, and this structure greatly facilitates manufacturing, and the guide groove is realized by the gap formed by the clamping arm 14 and the inner annular support plate 11, which is more convenient for plugging.

[0045] In order to further facilitate plugging, in this embodiment, the clamp 33 is an L-shaped structure, which includes a short arm 331 and a long arm 332 connected to each other, the short arm 331 is formed by a side wall of the outer annular groove 32 extending axially toward the lamp body 1, and the long arm 332 is extended from the end of the short arm 331 along the circumference of the outer annular groove 32. In order to strengthen the buckle structure, the length of the short arm 331 is greater than the thickness of the outer annular groove 32, and the length of the long arm 332 is less than the length of the outer annular groove 32.

[0046] In order to further strengthen the snap-on structure, a stop protrusion 333 is provided on the long arm 332 of the clip 33 (on the side away from the lamp body 1), and the stop protrusion 333 is arranged on the side of the long arm 332 close to the free end; correspondingly, a stop recess 141 is provided at the corresponding position of the clamping arm 14 of the outer annular fixing member 12. When the clip 33 is inserted into the clamping groove 13 of the outer annular fixing member 12, the stop protrusion 333 of the long arm 332 of the clip 33 is inserted into the stop recess 141 of the clamping arm 14. This structure firstly arranges the guide groove (i.e., the card slot 13) so that the card member 33 can be inserted into the card slot 13 more easily, thus facilitating the operation; then, the card arm 14 is arranged so that after the card member 33 is inserted into the card slot 13, the long arm 332 of the card member 33 forms a contact-type clamping position with the card arm 14 due to its elasticity (the L-shaped structure has a certain tension to form elasticity); finally, the anti-rotation concave point 141 and the anti-rotation convex point 333 are arranged to further strengthen the snap-on connection structure, thereby preventing the mounting bracket 3 and the lamp body 1 from being separated due to accidental rotation.

[0047] In order to further facilitate the precise positioning of the plug-in, a convex ring 15 is provided at the center position of the inner annular support plate 11 of the lamp body 1, and a through hole 34 is correspondingly provided on the inner annular mounting plate 31 of the mounting bracket 3. During installation, the through hole 34 of the mounting bracket is sleeved on the convex ring of the lamp body, and then the mounting bracket is rotated so that its clamp is inserted into the slot and fixed.

[0048] In this embodiment, see Figure 1, a receiving cavity 16 for receiving the power driver 5 is provided at the center of the lamp body 1, and the power driver 5 is installed between the lamp body 1 and the mounting bracket 3; the mounting bracket 3 is provided with a threading hole for leading out the wires of the power driver 5. In order to further clamp the power driver 5 and prevent it from shaking, the inner wall of the receiving cavity 16 of the lamp body 1 is provided with a groove 161, and the power driver 5 is provided with a hook 51 corresponding to the groove 161. When installing, the hook 51 of the power driver 5 is just clamped on the groove 161 of the receiving cavity 16 to fix the power driver 5 at the center of the lamp body 1. The power driver is provided to provide a stable power supply to the light source, and is connected to the light source inside the lamp housing and the external power source respectively. In the existing panel lamp, the power driver is generally connected by external wiring, that is, the power driver is exposed outside the lamp face frame. In this way, it often fails to meet the international certification system due to not paying attention to safety regulations during wiring, such as wire diameter and tensile test. At the same time, the external power driver increases the possibility of human contact, which is prone to safety problems. Not only does it have a large safety hazard, but it is also easy to cause the power driver to have nowhere to be placed during installation, which leads to complex installation and affects the aesthetics of the entire product in the application environment after installation. The present invention arranges a cavity for accommodating the power driver 5 at the center of the lamp body 1, and arranges the power driver 5 inside the lamp body 1, so there is no need to perform special requirements such as wire diameter and tensile test. At the same time, the built-in power driver 5 reduces the possibility of human contact and improves the overall safety. It is also convenient for the installation of the panel lamp as a whole, and the thickness of the product is reduced. After installation, the panel lamp is integrated with the application environment and is more beautiful.

[0049] In order to make the light softer, more uniform and more efficient, the multiple LEDs of the LED light source 2 are regularly spaced and arranged in a ring shape on the side of the outer annular fixing member 12 of the lamp body 1 pointing inward, and then arranged on the inner surface of the lamp body 1. In this embodiment, the LED light source 2 is a flexible light strip formed by a plurality of LEDs regularly spaced from each other on a flexible circuit board, and the flexible light strip is arranged in a ring shape on the side of the outer annular fixing member 12 of the lamp body 1 pointing inward. The inner surface of the lamp body 1 is in the shape of a disk, so that a homogeneous and uniform light impression is achieved respectively.

[0050] In order to make the light softer, more uniform and more efficient, a second annular support plate for carrying the light-emitting panel is provided on the lamp body 1, and the heat dissipation aluminum plate 6, the light guide plate 7 and the diffuser plate 8 are fixed on the second annular support plate in sequence. In order to facilitate heat dissipation, the LED light source 2 is arranged around the heat dissipation aluminum plate 6, and the LED light source 2 (multiple LEDs) faces the inside of the lamp body 1 and is opposite to the side of the light guide plate 7. Among them, the heat dissipation aluminum plate 6 can also change its shape, so that the light guide direction of the LED light source 2 arranged around the heat dissipation aluminum plate 6 changes, thereby further improving the light extraction efficiency. After the light from the LED light source 2 is guided by the light guide plate 7, it passes through the diffuser plate 8 for diffusing the light to form a light radiation surface. The diffuser plate 8 is arranged to cover the front of the light guide plate 7. The diffuser plate 8 homogenizes the inhomogeneous radiation characteristics generated by the multiple LEDs spaced apart from each other of the LED light source 2 and thus realizes a homogeneous and uniform light impression through the entire light radiation surface. The diffuser plate 8 homogenizes the light radiated by the LED light source 2 in terms of its spatial distribution and its angular distribution.

[0051] In addition, as an alternative to or in addition to the diffuser 8, the luminaire body 1 can also have an optical waveguide, which can also achieve homogeneous and uniform radiation of light from the LED light source 2 via, for example, scattering centers, reflection areas and / or light coupling output structures; as a feasible solution, in addition to the diffuser 8, a reflective film for reflecting light is also provided, and the reflective film is provided to cover the back of the light guide plate 7.

[0052] In which, the LED light source 2 radiates light with different colors and / or color temperatures, that is, the light radiated by each LED can be light of the same or different color temperatures, the same or different colors, for example, the light radiated by each LED is warm white light of the same color temperature; or the light radiated by each LED is a mixture of white, yellow and green light of different color temperatures.

[0053] In order to simplify the structure and facilitate production and installation, see Figure 1 , the circumference of the face ring 4 is provided with a spring sheet 41, and correspondingly, the lamp body 1 is provided with a groove 17 that cooperates with the spring sheet 41, so that the face ring and the lamp body are installed in a snap-on push-up fixing manner, which is convenient for assembly and replacement of the face ring. In actual production, the face ring can be made of PA thermal conductive plastic, which is flame retardant and has a delicate and beautiful appearance. In addition, the face ring can be replaced with different forms of face rings that match different scenes. Therefore, the lamp also has the advantages of beautiful and fashionable appearance and wide applicability.

[0054] It can be seen from the above that in the entire lamp body structure of the present invention, the connections between the mounting bracket, power driver, lamp body, heat dissipation aluminum plate, LED light source, light guide plate, diffuser plate and face ring from bottom to top are all achieved without screws, which not only facilitates installation, but also avoids the cumbersome assembly process and the occurrence of screw omissions when screws are fixed, reduces production costs, manufacturing processes and assembly difficulty, and is easy to disassemble, greatly facilitating installation and maintenance.

[0055] For ease of installation, see Figure 6 The mounting bracket 3 is provided with mounting holes 35, mounting ribs 36 and arrows 37 for indicating the direction of rotation. In order to further make the mounting bracket 3 universal, such as being universal for round, square or special shapes, the mounting ribs 36 include transverse ribs and vertical ribs. When the mounting bracket 3 is installed, the mounting ribs are aligned with the wall direction to ensure the consistency and matching between the lamp and the installation site after the lamp body is installed. At the same time, in order to facilitate heat dissipation, the mounting bracket 3 is also provided with array-arranged heat dissipation holes 38.

[0056] This embodiment provides an LED panel lamp that is easy to install, quick to disassemble and maintain through the above structure. In this embodiment, the lamp body, the light panel and the mounting bracket are respectively formed in the shape of a disc. The lamp body and the mounting bracket are rotated and fixedly installed. The lamp body and the mounting bracket are provided with 4 rotation positions, and the buckle structure is provided with anti-rotation concave and convex points. After installation, each group of anti-rotation concave points and anti-rotation convex points cooperate with each other. Figure 6 and Figure 7 During installation, first install the heat dissipation aluminum plate, flexible light strip, light guide plate, diffusion plate, face ring, etc. inside the lamp body to the lamp body, then install the power driver on the lamp body, and then fix the mounting bracket to the ceiling (or other locations to be fixed) with screws 9. Finally, the lamp body and the mounting bracket are connected by rotation and locked by limit bumps to prevent slipping.

The outer annular fixing member 12 has a card slot 13. The card member 33 of the outer annular card slot 32 is inserted into the card slot 13 of the outer annular fixing member 12 and rotated so that the mounting bracket 3 and the lamp body 1 can be connected in a rotating manner. In order to facilitate plugging and manufacturing, a card arm 14 is provided at a position corresponding to the card slot 13 on the outer annular fixing member 12. The card arm 14 is arranged parallel to the inner annular supporting plate 11, and the gap formed between the card arm 14 and the inner annular supporting plate 11 forms a guide groove for the card member 33 to enter the card slot 13. The card slot 13 of the outer annular fixing member 12 is directly formed by opening a groove, which greatly facilitates manufacturing, and the guide groove is realized by the gap formed by the card arm 14 and the inner annular supporting plate 11, which is more convenient for plugging.

[0063] For further convenience of plugging, see Fig.11 The clamp 33 is an L-shaped structure, which includes a short arm 331 and a long arm 332 connected to each other. The short arm 331 is located in the outer annular clamping groove 32 and extends axially toward the lamp body 1, and the long arm 332 extends from the end of the short arm 331 along the circumference of the outer annular clamping groove 32. In order to strengthen the buckle structure, the length of the short arm 331 is greater than the thickness of the outer annular clamping groove 32, and the length of the long arm 332 is extended (at least greater than 1 / 8 of the circumference of the outer annular clamping groove) to facilitate the buckle with the structure of the lamp body 1.

[0064] In order to further strengthen the buckle structure, a stop-rotation protrusion 333 is provided on the long arm 332 of the clamp 33 (on the side away from the lamp body 1), and there are several stop-rotation protrusions 333, which can be evenly or unevenly arranged; correspondingly, a stop-rotation recess 141 is provided at the corresponding position of the clamping arm 14 of the outer annular fixing member 12. When the clamp 33 is inserted into the clamping groove 13 of the outer annular fixing member 12, the stop-rotation protrusion 333 of the long arm 332 of the clamp 33 is inserted into a stop-rotation recess 141 of the clamping arm 14 to stop rotation. This structure firstly arranges the guide groove (i.e., the card slot 13) so that the card member 33 can be inserted into the card slot 13 more easily, thus facilitating the operation; then, the card arm 14 is arranged so that after the card member 33 is inserted into the card slot 13, the long arm 332 of the card member 33 forms a contact-type clamping position with the card arm 14 due to its elasticity (the L-shaped structure has a certain tension to form elasticity); finally, the anti-rotation concave point 141 and the anti-rotation convex point 333 are arranged to further strengthen the snap-on connection structure, thereby preventing the mounting bracket 3 and the lamp body 1 from being separated due to accidental rotation.

[0065] The present invention uses the structure of the clamp 33 and the clamping slot 13 to connect the mounting bracket 3 and the lamp body 1 in a snap-fit ​​fixed and rotatable manner. This structure is easier to install and disassemble, and the mounting bracket 3 is universal, so users can easily replace it.

[0066] Example 4

[0067] Different from Example 3, see Fig.15 and Fig.16 In this embodiment, the lamp body 1 is in a square shape, and the light emitting panel and the mounting bracket 3 are both in a disc shape. The other structures are the same as those in the third embodiment.

[0068] In addition, in addition to or in addition to the round or square lamp body of Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4, the lamp body can also be any other shape. It is sufficient to set the corresponding mounting rib position of the mounting bracket 3 according to the shape of the lamp body 1 during manufacturing. Therefore, the mounting bracket 3 has very good versatility and is widely applicable to lamp bodies 1 of various shapes.

[0069] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
