When the connecting seat is fixed with other components, the connecting seat serves as a main force receiving and supporting component and is often subjected to a large pulling force, which causes the connecting seat to be easily deformed. In related solutions, the connecting seat and the main body component of the lamp panel are connected through buckling. The force receiving points are few. When the overall weight of the lamp panel is large, the connecting position of the connecting seat and the lamp panel is easily deformed or even separated. CONTENT OF THE UTILITY MODEL

Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0035] It should be noted that, in the description of the present application, if the terms "first", "second" and the like appear, "first", "second" are only used for convenient description of different components or names, and cannot be understood as indicating or implying the order relationship, relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, if "and / or" appears throughout the text, it means that it includes three parallel solutions. For example, "A and / or B" includes A solution, or B solution, or A and B solutions.

[0036] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a frame assembly of a lamp panel, which comprises a fixed frame 10, an optical film 20, a reflective layer 30, a connecting seat 40 and two pressing plates 50. The optical film 20, the reflective layer 30 and the connecting seat 40 are sequentially arranged along the axial direction of the fixed frame 10. The connecting seat 40 is provided with an electrical interface 41 to be connected to a power supply. The two pressing plates 50 are distributed on the two opposite sides of the connecting seat 40. The edge of the pressing plate 50 is overlapped with the edge of the connecting seat 40, and the pressing plate 50 is abutted on the side of the connecting seat 40 away from the reflective layer 30. The pressing plate 50 is detachably connected with the fixed frame 10.

[0037] Specifically, the optical film 20 can include a light guide plate 21, a diffusion plate 22, a soft light plate and the like optical elements. The light emitted by the light source is processed by the optical film 20 and then emitted from the frame assembly. In addition, the reflective layer 30 reflects the corresponding light to the optical film 20, so that the reflective layer 30 can block the light from being emitted to the side where the connecting seat 40 is located.

[0038] The two pressing plates 50 and the connecting seat 40 jointly splice to form an integral whole, and the integral whole is located on the side of the reflective layer 30 away from the optical film 20.

[0039] The connecting seat 40 serves as an adapter structure, which is an electrical adapter structure to connect the light source to the power supply. Specifically, the electrical interface 41 on the connecting seat 40 can be plugged with a male or female connector to achieve connection with the power supply. The connecting seat 40 also serves as a mechanical installation adapter structure, which can be fixed to a connecting rod 300 for use as a table lamp or floor lamp. The power supply can refer to a rechargeable power supply located in a mounting seat 200 (described in the later embodiment), or the power supply can refer to a mains electricity.

[0040] In the embodiment, the two side edges of the connecting seat 40 are abutted by the two pressing plates 50 respectively, so that the connecting seat 40 is prevented from being separated from the fixed frame 10. Since the pressing plates 50 are fixed to the fixed frame 10, the force received by the connecting seat 40 can be transferred to the pressing plates 50, so that the force received by the connecting seat 40 is reduced. Meanwhile, since the pressing plates 50 are overlapped with the edges of the connecting seat 40, it means that the contact area between the pressing plates 50 and the connecting seat 40 is large, and the pressing force of the pressing plates 50 on the connecting seat 40 is dispersed to the whole edge, so that the risk of deformation of the connecting seat 40 due to excessive local force is avoided, and the risk of separation of the connecting seat 40 from the fixed frame 10 is reduced.

[0041] Please refer to Figure 3 In some embodiments, the inner wall of the fixed frame 10 is provided with a support rib 13 extending along the circumference of the fixed frame 10. Specifically, the fixed frame 10 has a ring-shaped frame structure, such as a square frame or a circular ring-shaped frame, and the axial direction of the fixed frame 10 refers to the through direction. The fixed frame 10 has a first side 11 and a second side 12 distributed along the axial direction thereof, the first side 11 is provided with a limiting plate 14 protruding inward, the limiting plate 14 extends along the circumference of the fixed frame 10 to form a ring shape, the support rib 13 is arranged on the limiting plate 14 and protrudes toward the second side 12, and the support rib 13 is arranged close to the inner wall of the fixed frame 10. The optical film 20 is overlapped on the side of the limiting plate 14 facing the second side 12 to avoid being separated from the fixed frame 10 in the direction of the first side 11, and the support rib 13 is wrapped on the outer side of the optical film 20.

[0042] Please refer to Figures 3 to 5 In some embodiments, the side of the connecting seat 40 facing the reflective layer 30 is provided with a limiting groove 42, and the support rib 13 is clamped with the limiting groove 42. In this way, the connecting seat 40 is clamped by the support rib 13 and the pressing plate 50 together, so that the connecting seat 40 is prevented from being separated from the fixed frame 10. Moreover, the clamping of the limiting groove 42 and the support rib 13 not only can pre-position the installation of the connecting seat 40, but also can prevent the connecting seat 40 from moving in the thickness direction of the support rib 13. In addition, the two sides of the connecting seat 40 are abutted by the pressing plates 50, and the other two sides of the connecting seat 40 are supported by the support rib 13, so that the force received by the connecting seat 40 is balanced.

[0043] In some embodiments, the support rib 13 is ring-shaped, and the structure formed by the two pressing plates 50 and the connecting seat 40 together covers the support rib 13, and the side of the pressing plate 50 facing the reflective layer 30 is overlapped with the support rib 13. In the embodiment, the pressing plate 50 is supported and positioned by the support rib 13, and the connecting seat 40 is also supported and positioned by the support rib 13, the positioning basis of the pressing plate 50 and the connecting seat 40 is the same, which is the support rib 13, so that the positioning accuracy between the pressing plate 50 and the connecting seat 40 is high.

[0044] Please refer to Figure 4 , Figure 6 and Figure 7 In some embodiments, the connecting seat 40 is a metal die casting and includes a main body part 43 and two flanges 44 integrally die cast. The two flanges 44 are distributed on two opposite sides of the main body part 43, and the flanges 44 are arranged close to the side of the main body part 43 facing the light-reflecting layer 30. The pressing plate 50 abuts against the side of the flanges 44 away from the light-reflecting layer 30. In this embodiment, the main body part 43 and the flanges 44 form a shape similar to a step, and the side of the flanges 44 away from the light-reflecting layer 30 is lower than the side of the main body part 43 away from the light-reflecting layer 30. Therefore, when the pressing plate 50 abuts against the side of the flanges 44 away from the light-reflecting layer 30, the pressing plate 50 can be prevented or reduced from protruding from the side of the main body part 43 away from the light-reflecting layer 30, so that the surface of the structure formed after the pressing plate 50 and the connecting seat 40 are spliced is more flat, and the flatness of the bottom plate 80 as an appearance part can be ensured when the bottom plate 80 is covered on the pressing plate 50 and the connecting seat 40.

[0045] The connecting seat 40 is provided with a quick-release structure to be fixed with the connecting rod 300 of the lighting lamp. The quick-release structure can be a rotating buckle, a push-pull buckle or the like, and the quick-release structure can be clamped or disengaged after being rotated or pushed and pulled. Since the connecting seat 40 is the connecting main body with the connecting rod 300, the stress is large, and in some embodiments, the height dimension of the connecting seat 40 is large (for example, protruding out of the bottom plate 80), so the structural strength of the connecting seat 40 is required to be high, and therefore the manufacturing process of metal die casting and machining is adopted accordingly.

[0046] In some embodiments, the connecting seat 40 is also detachably connected with the fixed frame 10. Specifically, the connecting seat 40 and the fixed frame 10 can be fixed by screws, and the pressing plate 50 and the fixed frame 10 can also be fixed by screws. Of course, in other embodiments, the detachable connection mode can also be clamping. In this embodiment, the connecting seat 40 has double fixing positions: one is that the connecting seat 40 is fixed with the fixed frame 10, and the other is that the connecting seat 40 is abutted by the pressing plate 50. The double fixing greatly reduces the risk of disengagement of the connecting seat 40 from the fixed frame 10, and also disperses the stress of the connecting seat 40, avoiding concentrated stress.

[0047] Please refer to Figure 8 and Figure 9Further, the elastic separation layer 60 is arranged between the pressing plate 50 and the light reflection layer 30, and the elastic separation layer 60 separates the fixed frame 10 into two regions along the axial direction of the fixed frame 10, one of which is provided with the main light source 71 and the other of which is provided with the auxiliary light source 72. The elastic separation layer 60 has the function of light shielding, and can avoid the light emitted by the main light source 71 from affecting the auxiliary light source 72, and vice versa. In addition, the elastic separation layer 60 also has the function of heat insulation, and can isolate the heat conducted downward from the circuit board on the connecting seat 40 and the two auxiliary light sources 72, and isolate the heat conducted upward from the circuit board of the main light source 71, so that the heat generated in the upper and lower two regions is isolated from each other.

[0048] The elastic separation layer 60 has a large size and can cover the light reflection layer 30 completely. In addition, the edge of the elastic separation layer 60 is in contact with the inner wall of the fixed frame 10, and can elastically fill the gap between the fixed frame 10 and the light reflection layer 30. The elastic separation layer 60 can be made of foam, sponge or other materials with elasticity and light shielding and heat insulation functions.

[0049] Please refer to Figure 10 and Figure 11 In some embodiments, the pressing plate 50 is a metal piece, and the pressing plate 50 is formed with an abutting convex 51 by integral recessing. The abutting convex 51 abuts the elastic separation layer 60 to the light reflection layer 30. Since the pressing plate 50 is not only connected with the fixed frame 10 but also limits the connecting seat 40, the pressing plate 50 is subjected to a large force, and therefore has a large requirement for structural strength. In the present embodiment, the pressing plate 50 is made of a metal piece, which can have a large structural strength. The abutting convex 51 formed by integral recessing has a double effect, one of which is to produce an effect similar to a reinforcing rib, thereby further strengthening the strength of the pressing plate 50, and the other of which is to jointly hold the elastic separation layer 60 with the light reflection layer 30 to limit the elastic separation layer 60.

[0050] Since the pressing plate 50 is formed with the abutting convex 51 by integral recessing, one side of the pressing plate 50 forms a concave cavity 52, and the opposite side forms the abutting convex 51. The auxiliary light source 72 is arranged in the concave cavity 52, and therefore the space is reasonably utilized, so that the structure is more compact.

[0051] The pressing plate 50 can be provided with a plurality of abutting convexes 51, such as Figure 11 In the present embodiment, the first abutting convex 511 is arranged in the middle region, and a plurality of second abutting convexes 512 are arranged on both sides. The plurality of abutting convexes 51 jointly form a plurality of abutting positions on the elastic separation layer 60. The auxiliary light source 72 is arranged in the concave cavity 52 formed by the first abutting convex 511.

[0052] Further, the pressing plate 50 is punched to form a plurality of heat dissipation holes 53. Specifically, the abutting convex 51 and other positions of the pressing plate 50 are provided with a plurality of heat dissipation holes 53. The arrangement of the heat dissipation holes 53 can enhance the heat dissipation effect of the auxiliary light source 72, and the heat generated by the connecting seat 40 can also be dissipated through the heat dissipation holes 53.

[0053] Please refer again to Figure 2 Further, the connecting seat 40 is provided with a radar 45, and the elastic layer 60 is provided with a avoiding hole 61 corresponding to the radar 45. Specifically, the connecting seat 40 is provided with a circuit board, which is connected with the electrical interface 41, the main light source 71 and the auxiliary light source 72 through wires, and the radar 45 is arranged on the circuit board. The radar 45 emits signals to the side where the light guide plate 21 is located, and can detect whether the user is close to the lamp panel 100. When the user is close to the lamp panel 100, the lamp panel 100 is automatically turned on; when the user is away from the lamp panel 100, the lamp panel 100 is automatically turned off.

[0054] Further, the frame assembly of the lamp panel further comprises a bottom plate 80, which covers the side of the pressing plate 50 away from the reflecting layer 30 and covers the one side (second side 12) of the fixed frame 10. The bottom plate 80 is provided with a avoiding hole 81 for a part of the connecting seat 40 to pass through, so that the bottom plate 80 can accommodate and hide most of the other structures such as the pressing plate 50, the connecting seat 40, the reflecting layer 30 and the like to the inside of the fixed frame 10. In addition, the bottom plate 80 and the fixed frame 10 are metal structures. In the embodiment, the bottom plate 80 is used as an appearance part to hide most of the pressing plate 50 and the connecting seat 40 inside, and plays a protective role. The bottom plate 80 and the fixed frame 10 are both metal structures such as aluminum, which have strong structural strength and large hardness, and can reduce the risk of being scratched. The bottom plate 80 can be fixed with the pressing plate 50, or the bottom plate 80 can be fixed with the fixed frame 10. Specifically, the bottom plate 80 is adhered with the pressing plate 50 by glue or double-sided adhesive tape.

[0055] The embodiment of the present application also provides a lighting lamp, which can be a desk lamp, a floor lamp or a ceiling lamp, etc. Please refer to Figure 1 and Figure 2 The lighting lamp comprises a mounting seat 200, a connecting rod 300 and a lamp panel 100. The lamp panel 100 comprises a main light source 71, an auxiliary light source 72 and a frame assembly of the lamp panel. The main light source 71 and the auxiliary light source 72 are distributed on two opposite sides of the reflecting layer 30. Specifically, the main light source 71 can be side-in type, and the auxiliary light source 72 is direct type and emits light to the side away from the light guide plate 21. The specific structure of the frame assembly of the lamp panel can refer to the above-mentioned embodiments, which will not be described here. In some embodiments, the lamp panel 100 is flat, and the thickness direction of the lamp panel 100 is the same as the axial direction of the fixed frame 10.

[0056] The mounting base 200 can be a disc-shaped or square flat structure, and has a supporting effect. The lower end of the connecting rod 300 is fixed to the mounting base 200, and the upper end of the connecting rod 300 is detachably connected to the connecting base 40. The connecting rod 300 can be a telescopic rod, so that the height of the lamp panel 100 can be adjusted. The connecting rod 300 can specifically be a vertical rod, or the connecting rod 300 can adopt an L-shaped rod structure.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that the technical solutions described in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
