[0047] Embodiment 1:
[0048] like Figure 1 and Figure 2 As shown, the flat panel lamp 100 of the first embodiment of the present application includes a flat panel lamp 10, which includes a lamp frame 13, a back plate 12, a diffuser 11 and a light source assembly. The diffuser 11 and the back plate 12 are both connected to the lamp frame 13 to form an assembly cavity, and the light source assembly is installed in the assembly cavity. The light source assembly emits light, and the light is radiated from the diffuser 11 for illumination.
[0049] like Figure 2 , Figures 5 to 7As shown, the flat panel lamp 100 of the first embodiment of the present application further includes a bracket 20, a plurality of third hook structures 30 and a plurality of fourth hook structures 40. The bracket 20 is used to be fixedly installed on the ceiling. The bracket 20 includes a first mounting portion 21, a second mounting portion 22 and a connecting portion 24 arranged at intervals along the first direction X. The first mounting portion 21 and the second mounting portion 22 are respectively connected to the two ends of the connecting portion 24, thereby obtaining a bracket 20 of an integrated structure. The first mounting portion 21 is provided with a plurality of first hook structures 211 arranged at intervals along the second direction Y, and the second mounting portion 22 is provided with a plurality of second hook structures 221 arranged at intervals along the second direction Y. The third hook structure 30 is connected to the back plate 12, and the third hook structure 30 is opened along the first direction X. The plurality of third hook structures 30 are arranged one-to-one with the plurality of first hook structures 211. The fourth hook structure 40 is opened along the first direction X, and multiple fourth hook structures 40 are arranged one by one corresponding to multiple second hook structures 221. The fourth hook structure 40 includes a connected pre-installed part 41 and a hook part 42. The hook part 42 is connected to the back plate 12, and the pre-installed part 41 extends obliquely relative to the back plate 12.
[0050] When the flat panel lamp 10 is installed on the ceiling, the pre-installed portion 41 is first hooked with the second hook structure 221 so that the back plate 12 is tilted relative to the ceiling. Fig.10 As shown, at this time, there is a gap between the side of the flat panel lamp 10 away from the ceiling and the ceiling, and the staff can observe the pre-installed part 41 from the gap, that is, the relative position of the fourth hooking structure 40 and the second hooking structure 221 can be observed, so that the staff can quickly complete the hooking of the pre-installed part 41 and the second hooking structure 221, thereby using the hooking of the pre-installed part 41 and the second hooking structure 221 to temporarily assist the staff in holding the flat panel lamp 10. After the pre-installed part 41 is hooked with the second hooking structure 221, the third hooking structure 30 moves toward the ceiling, and the third hooking structure 30 is opposite to the first hooking structure 211. Then, the flat panel lamp 10 moves along the first direction X so that the third hooking structure 30 is hooked with the first hooking structure 211 and the hooking part 42 is hooked with the second hooking structure 221, thereby completing the ceiling installation of the flat panel lamp 10 on the ceiling.
[0051] When the flat panel lamp 100 provided by the present application is used for ceiling installation, the staff first fixes the bracket 20 to the ceiling, and then installs the flat panel lamp 10 to the ceiling by hooking. During the installation process, since the pre-installed portion 41 extends obliquely relative to the back plate 12, after the pre-installed portion 41 is hooked with the second hooking structure 221, there is a gap between the side of the flat panel lamp 10 away from the ceiling and the ceiling, and the staff can observe the relative position of the fourth hooking structure 40 and the second hooking structure 221 through the gap. In this way, the staff is no longer performing blind installation. Therefore, the staff can quickly complete the hooking of the pre-installed part 41 with the second hooking structure 221, and then quickly align the third hooking structure 30 with the first hooking structure 211, and then push the flat panel lamp 10 along the first direction X, so that the third hooking structure 30 is hooked with the first hooking structure 211 and the hooking part 42 is hooked with the second hooking structure 221, thereby completing the ceiling installation of the flat panel lamp 10 on the ceiling, and the installation efficiency is greatly improved.
[0052] like Fig. 9 As shown, the first mounting portion 21 further includes a plurality of first limiting portions 212, and the plurality of first limiting portions 212 are arranged in a one-to-one correspondence with the plurality of first hooking structures 211. Figure 4 , Fig. 9 and Fig.11 As shown, the third hook structure 30 is provided with a second limiting portion 31. The first limiting portion 212 and the second limiting portion 31 cooperate with each other when the first hook structure 211 and the third hook structure 30 are hooked, so as to limit the first hook structure 211 and the third hook structure 30 from being separated from each other. In this way, under the mutual restriction between the first limiting portion 212 and the second limiting portion 31, even if the flat panel lamp 10 is accidentally touched by a foreign object, the third hook structure 30 and the first hook structure 211 are not easily separated from each other, so that the flat panel lamp 10 can be stably mounted on the ceiling.
[0053] like Figure 8 As shown, the second mounting portion 22 further includes a plurality of third limiting portions 222, and the plurality of third limiting portions 222 are arranged in a one-to-one correspondence with the plurality of second hooking structures 221. Figure 3 , Figure 8 and Fig.12As shown, the fourth hook structure 40 also includes a fourth limiting portion 43. The third limiting portion 222 and the fourth limiting portion 43 cooperate with each other when the hook portion 42 is hooked with the second hook structure 221 to limit the hook portion 42 from being separated from the second hook structure 221. In this way, under the mutual restriction between the third limiting portion 222 and the fourth limiting portion 43, even if the flat panel lamp 10 is accidentally touched by a foreign object, the fourth hook structure 40 and the second hook structure 221 are not easily separated from each other, so that the flat panel lamp 10 can be stably mounted on the ceiling.
[0054] In the flat panel lamp 100 of the first embodiment of the present application, preferably, the first limiting portion 212 and the second limiting portion 31 are mutually restricted, and at the same time, the third limiting portion 222 and the fourth limiting portion 43 are mutually restricted, so that the flat panel lamp 10 can be more stably mounted on the ceiling. In some embodiments of the present application, the first limiting portion 212 and the second limiting portion 31 may be mutually restricted, but no restricting structure is provided between the second hook structure 221 and the fourth hook structure 40. Alternatively, in other embodiments of the present application, the third limiting portion 222 and the fourth limiting portion 43 are mutually restricted, but no restricting structure is provided between the first hook structure 211 and the third hook structure 30.
[0055] In the flat panel lamp 100 of the first embodiment of the present application, one of the first limiting portion 212 and the second limiting portion 31 is a slot, and the other of the first limiting portion 212 and the second limiting portion 31 is a protrusion. In addition, one of the third limiting portion 222 and the fourth limiting portion 43 is a slot, and the other of the third limiting portion 222 and the fourth limiting portion 43 is a protrusion. Preferably, as Fig. 9 As shown, the first limiting portion 212 is a slot, and the second limiting portion 31 is a protrusion; Figure 8 As shown, the third limiting portion 222 is a slot, and the fourth limiting portion 43 is a protrusion. When the flat panel lamp 10 is pushed horizontally along the first direction X so that the third hooking structure 30 is hooked with the first hooking structure 211 and the hooking portion 42 is hooked with the second hooking structure 221, the protrusion will make a "click" sound when it is caught in the convex slot, so that the staff can judge that the flat panel lamp 10 has been installed on the ceiling. The protrusion is caught in the slot and is restricted and cannot move along the first direction X, that is, the flat panel lamp 10 cannot move along the first direction X, so that the flat panel lamp 10 can be stably installed on the ceiling.
[0056] In the flat panel lamp 100 of the first embodiment of the present application, the pre-installed portion 41 and the hook portion 42 are integrally formed. That is, the fourth hook structure 40 is punched out of steel material, thereby integrally forming the pre-installed portion 41 and the hook portion 42. Similarly, the third hook structure 30 is also punched out of steel material to obtain an integrally formed third hook structure 30. In this way, the processing efficiency of the third hook structure 30 and the fourth hook structure 40 is greatly improved, and the consistency is good.
[0057] When the flat panel lamp 10 is pushed horizontally along the first direction X so that the third hooking structure 30 is hooked with the first hooking structure 211 and the hooking portion 42 is hooked with the second hooking structure 221, in order to enable the third hooking structure 30 to smoothly hook with the first hooking structure 211, Fig.11 As shown, the third hooking structure 30 is further provided with a guiding inclined surface 32. When the flat panel lamp 10 is pushed horizontally along the first direction X, the first hooking structure 211 slides along the guiding inclined surface 32, so that the third hooking structure 30 and the first hooking structure 211 are hooked smoothly.
[0058] like Figure 6 As shown, the number of the third hook structures 30 is two. In addition, the two third hook structures 30 are locked to the back plate 12 by screws 50 or riveted to the back plate 12. Figure 6 As shown, there are two fourth hook structures 40, and the two fourth hook structures 40 are locked to the back plate 12 by screws 50 or riveted to the back plate 12. Preferably, in the flat panel lamp 100, the two third hook structures 30 and the two fourth hook structures 40 are both locked to the back plate 12 by screws 50.
[0059] Embodiment 2:
[0060] like Fig.13 As shown, it shows the flat panel lamp 100 of the second embodiment of the present application, which has the following differences from the flat panel lamp 100 of the first embodiment.
[0061] like Fig.13As shown, the bracket 20 further includes a guide portion 23, which is disposed adjacent to the second mounting portion 22 and is located between the first mounting portion 21 and the second mounting portion 22. The guide portion 23 is provided with a plurality of guide fins 231 corresponding to the plurality of second hook structures 221, and the pre-installed portion 41 abuts against the guide fins 231 when the third hook structure 30 moves toward the ceiling. In addition, the molded pre-installed portion 41 has elasticity. That is, when the third hook structure 30 moves toward the ceiling and faces the first hook structure 211, the pre-installed portion 41 abuts against the guide fins 231, and the guide fins 231 exert a downward pressure on the pre-installed portion 41. Therefore, when the third limiting portion 222 and the fourth limiting portion 43 restrict each other, under the action of the downward pressure, the third limiting portion 222 and the fourth limiting portion 43 restrict each other more firmly, and even if the flat panel lamp 10 is accidentally touched by foreign objects, the fourth hook structure 40 and the second hook structure 221 are not easy to separate from each other, so that the flat panel lamp 10 can be more stably mounted on the ceiling. In addition, the guide fin plate 231 blocks the pre-installed portion 41 from directly contacting the ceiling, thereby preventing the pre-installed portion 41 from scratching the ceiling when the flat panel lamp 10 is pushed horizontally along the first direction X, and keeping the ceiling flat.
[0062] The flat panel lamp 100 of the second embodiment is compared with the flat panel lamp 100 of the first embodiment. Except for the above differences, the rest of the structures are the same, so they are not described again.
[0063] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
