[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] In the claims, specification and the above drawings of the present utility model, unless otherwise clearly defined, the terms "first", "second" or "third" are used to distinguish different objects, rather than to describe a specific order. In the claims, specification and the above drawings of the present utility model, the terms "upper", "lower", "top" and "bottom" are the same as the up and down directions of the panel light after actual installation. The term "front" refers to the side where light is emitted, and the term "back" refers to the side where the backlight is not emitted. The remaining directional words are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the specific protection scope of the present utility model.

[0037] In the claims, specification and the above drawings of the utility model, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.

[0038] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0039] Please also read Figures 1 to 10 Now, the panel light with replaceable power supply provided by the utility model is described. The panel light with replaceable power supply comprises a lamp body 10, a power module 20 and a connector 30. The back of the lamp body 10 is recessed to form a receiving cavity 12, and a first contact spring 11 is provided on one side of the receiving cavity 12; the power module 20 is placed in the receiving cavity 12, and the back of the power module 20 does not protrude from the back of the lamp body 10. A second contact spring 21 corresponding to the first contact spring 11 is provided on one side wall of the power module 20 to achieve electrical conduction; the connector 30 is connected between the power module 20 and the lamp body 10.

[0040] It is easy to understand that the second contact spring 21 is electrically connected to the circuit inside the power module 20, and the first contact spring 11 is electrically connected to the light-emitting module in the lamp body 10. Therefore, when the first contact spring 11 contacts the second contact spring 21, electrical conduction is achieved, so that turning on the power module 20 can directly drive the lamp body 10 to emit light.

[0041] Compared with the prior art, the panel lamp with replaceable power supply provided in this embodiment needs to assemble the power module 20 and the lamp body 10 before use, place the power module 20 in the accommodating cavity 12, and adjust the position of the power module 20 so that the second contact spring 21 fits on the first contact spring 11, and then fix the position of the power module 20 by the connecting piece 30, so that it can be used normally. When the power module 20 needs to be replaced or repaired, the connecting piece 30 can be directly removed for operation. The power module 20 in the panel lamp with replaceable power supply of the utility model is arranged in the accommodating cavity 12 of the lamp body 10 and fixed by the connecting piece 30, so that the power module 20 can be disassembled conveniently, and then the power module 20 can be repaired or replaced conveniently; the structure of the first contact spring 11 and the second contact spring 21 is used for electrical conduction, which is lower in cost than the traditional wire connection or PIN connection, and the frequent disassembly of the power module 20 will not cause poor plugging.

[0042] In some embodiments, an improved implementation of the power module 20 may be as follows: Figures 2 to 3 and Figure 6 See the structure shown. Figures 2 to 3 and Figure 6 The side wall of the power module 20 is provided with a plurality of grooves 23 , each groove 23 is provided with a second contact spring 21 , and the number of the first contact springs 11 is equal to the number of the second contact springs 21 .

[0043] The grooves 23 are provided to protect the second contact springs 21, thereby preventing the second contact springs 21 from being directly exposed to the outside and being worn when the power module 20 is transported separately. Since each groove 23 is independent of each other, when the first contact springs 11 extend into the grooves 23, it is ensured that each first contact spring 11 only contacts one second contact spring 21, thereby achieving a one-to-one corresponding connection between the two and a better connection effect.

[0044] It should be noted that the first contact spring 11 needs to extend into the groove 23 to achieve contact with the first contact spring 11, so the first contact spring 11 needs to have a structure extending toward the second contact spring 21, for example: the first contact spring 11 has an extension portion extending toward the second contact spring 21, and the free end of the extension portion is bent downward. After the first contact spring 11 and the second contact spring 21 are in contact, they abut against the extension portion. At this time, the extension portion undergoes a certain deformation due to its own elasticity. After the power module 20 is fixed, the extension portion can continuously abut against the second contact spring 21, and the connection structure is more stable and is not easily disconnected due to external factors such as vibration; and the free end of the extension portion (i.e., the end facing the second contact spring 21) is bent downward, which can ensure that the arc surface abuts against the second contact spring 21, avoiding the tip contacting the second contact spring 21 to cause wear and tear, thereby extending the service life.

[0045] In some embodiments, an improved implementation of the power module 20 may be as follows: Figure 3 See the structure shown. Figure 3 The second contact spring 21 fits the bottom surface of the groove 23, and a stopper 24 is also provided on the top wall of each groove 23. The stopper 24 is used to limit the second contact spring 21 on the side close to the first contact spring 11. After the second contact spring 21 is installed, since the stopper 24 is located on the side of the second contact spring 21 facing the first contact spring 11, and the bottom surface of the stopper 24 is lower than the top surface of the second contact spring 21, it can be prevented that the second contact spring 21 no longer fits the bottom surface of the groove 23 due to its own elasticity, thereby causing poor contact with the first contact spring 11.

[0046] Specifically, the cross-sectional shape of the stopper 24 is a right triangle, the side corresponding to one right angle side is fixedly connected to the top wall of the groove 23, and the side corresponding to the other right angle side faces the second contact spring 21. A fixing plate 25 is provided inside the power module 20, and a plug 26 is bent downward on the fixing plate 25, and the plug 26 is matched with the plug hole on the power module 20. The second contact spring 21 is integrally formed with the fixing plate 25 and extends out of the outside of the power module 20. After the second contact spring 21 extends out of the power module 20, it needs to fit the bottom surface of the groove 23. In this process, the top of the second contact spring 21 passes through the inclined surface on the stopper 24 and is installed in the groove 23, which makes installation more convenient.

[0047] In some embodiments, an improved implementation of the lamp body 10 can be as follows: Figures 1 to 3 , Figure 5 , Figures 8 to 10 See the structure shown. Figures 1 to 3 , Figure 5 , Figures 8 to 10 , a limiting plate 13 is provided on the top of one side wall of the accommodating cavity 12 on which the first contact spring 11 is provided, and the limiting plate 13 is located above the first contact spring 11, and a limiting groove 22 corresponding to the limiting plate 13 is formed on the top of the power module 20. The top surface of the limiting plate 13 is flush with the back surface of the lamp body 10. After the power module 20 is loaded into the accommodating cavity 12, it is necessary to slide the power module 20 to the bottom of the limiting plate 13 so that the first contact spring 11 and the second contact spring 21 abut, and then fix the power module 20. This structure can make the connection between the power module 20 and the lamp body 10 more stable. On the basis of setting the limiting plate 13, the side of the power module 20 provided with the second contact spring 21 can be fixed, and then the connecting member 30 can be centrally arranged on the side of the power module 20 away from the second contact spring 21, thereby facilitating the installation of the power module 20 and reducing the labor intensity.

[0048] In order to allow the power module 20 to slide in the accommodating cavity 12 , the length of the accommodating cavity 12 needs to be longer than the power module 20 , thereby ensuring that the power module 20 can slide into the bottom of the limiting plate 13 .

[0049] Specifically, the bottom surface of the limit groove 22 is an inclined surface that gradually slopes downward toward the direction of the first contact spring 11. The lowest height of the limit groove 22 is lower than the bottom surface of the limit plate 13, and then when the power module 20 slides into the bottom of the limit plate 13, the inclined surface contacts the limit plate 13, preventing the power module 20 from being stuck against the limit plate 13 and being unable to move forward, making installation easier.

[0050] In some embodiments, an improved implementation of the above-mentioned accommodating cavity 12 can be as follows Figure 2 and Figure 5 See the structure shown. Figure 2 and Figure 5 A sinking groove 15 is provided at the bottom of the accommodating cavity 12, and the power module 20 is engaged with the sinking groove 15. The shape of the sinking groove 15 is adapted to the shape of the power module 20. When the power module 20 slides into the bottom of the limiting plate 13 (i.e., the limiting plate 13 slides into the limiting groove 22), once the power module 20 slides into place, the power module 20 is embedded in the groove 23, so that the positioning of the power module 20 can be realized, and the installation of the connector 30 is convenient.

[0051] In some embodiments, an improved connection structure between the power module 20 and the lamp body 10 can be as follows: Figure 4 and Figure 7 See the structure shown. Figure 4 and Figure 7 The power module 20 is provided with a positioning cavity 27 and a through hole 28 communicating with the positioning cavity 27. The accommodating cavity 12 is fixed with a mounting post 14, which is located in the positioning cavity 27 and coaxial with the through hole 28. The connecting piece 30 passes through the through hole 28 and is connected with the mounting post 14. In order to satisfy the sliding process of the power module 20, the positioning cavity 27 can satisfy the relative sliding of the mounting post 14. When the power module 20 is placed in the accommodating cavity 12, the mounting post 14 is located in the positioning cavity 27. After the power module 20 is installed in place, the mounting post 14 is coaxial with the through hole 28. At this time, the connecting piece 30 can be installed.

[0052] Optionally, the connector 30 is threadedly connected or plugged with the mounting post 14. When threaded connection is adopted, the connector 30 is a screw, and the mounting post 14 is provided with a corresponding internal threaded hole; when plug connection is adopted, the connector 30 is a latch, and the mounting post 14 is provided with a corresponding socket.

[0053] In some embodiments, a modified connection structure between the power module 20 and the lamp body 10 may be as follows: Figures 8 to 10 See the structure shown. Figures 8 to 10The lamp body 10 also has a mounting groove 16 located on the side wall of the accommodating cavity 12 and connected to the accommodating cavity 12. The side wall of the power module 20 is provided with a mounting block 29 for extending into the mounting groove 16. The connecting member 30 is connected between the mounting block 29 and the lamp body 10.

[0054] The mounting groove 16 can have two forms: (1) Fig.10 The bottom surface of the mounting groove 16 is higher than the bottom surface of the accommodating cavity 12, and the top surface is flush with the back surface of the lamp body 10; (2) See Figures 8 to 9 The bottom surface of the mounting groove 16 is flush with the bottom surface of the accommodating cavity 12 , and the top surface is spaced apart from the back surface of the lamp body 10 .

[0055] In the above embodiment (1), a socket or threaded hole connected to the connector 30 needs to be opened at the bottom of the mounting groove 16 , and the connector 30 passes through the mounting block 29 and is connected to the socket or threaded hole to fix the power module 20 .

[0056] In the above (2) embodiment, it is necessary to open a through hole on the top wall of the mounting groove 16, and to open a socket or threaded hole connected to the connecting member 30 on the mounting block 29. The connecting member 30 passes through the through hole and is plugged or screwed to the mounting block to fix the power block 20.

[0057] Specifically, one or more mounting slots 16 may be provided, for example, Fig.10 When two mounting grooves 16 are provided, the two mounting grooves 16 can be located on two opposite side walls of the accommodating cavity 12; see Figure 8 Alternatively, both mounting grooves 16 may be located on a side wall of the accommodating cavity 12 where the first contact spring 11 is installed, and the two mounting grooves 16 may be located on both sides of the first contact spring 11 .

[0058] The number of the mounting blocks 29 is equal to or different from the number of the mounting grooves 16 . The shape of the mounting blocks 29 is adapted to the shape of the mounting grooves 16 , and the cross-section thereof may be triangular, rectangular, or the like.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
