The whole lamp is designed beautifully, simply, grandly and luxuriously. It not only has a good lighting effect, but also can bring people a beautiful feeling. The LED panel lamp has a unique design. After the light passes through a light guide plate with a high light transmittance, a uniform planar light-emitting effect is formed. The illuminance uniformity is good, the light is soft, comfortable and not lacking in brightness, and it can effectively relieve eye fatigue.

[0003] The prior art is an invention patent named Panel Lamp Installation Structure, Panel Lamp and Its Installation Method, and the publication number of this invention patent is US20210341114A1. This invention discloses a panel lamp installation structure, a panel lamp and its installation method. The panel lamp installation structure includes a fixing groove provided on the back of the lamp body and an installation bracket that is snap-fitted with the fixing groove. The first clamping plate in the installation bracket slides into the first fixing groove through the first accommodating surface, and at the same time is snap-fitted with the first fixing groove through the first abutting surface and the second abutting surface. The second clamping plate in the installation bracket slides into the second fixing groove through the second accommodating surface and the third accommodating surface, and at the same time is snap-fitted with the second fixing groove through the third abutting surface and the fourth abutting surface. This invention uses a sliding snap-fitting method to match and connect the lamp body of the panel lamp with the installation bracket. The installation is convenient and fast, and the ceiling effect is excellent. In addition, this invention can also realize the blind operation during the installation process of the panel lamp. However, this invention has insufficient heat dissipation and shock absorption effects for the panel lamp. Summary of the Invention

[0004] The purpose of the present invention is to provide a housing connection structure of a panel lamp and a panel lamp with balanced heat dissipation and buffering and good fastening effect.

[0005] The technical solution adopted by the present invention to achieve the above purpose is as follows:

[0006] The housing connection structure of the panel lamp includes a connection base body. One side of the connection base body has an installation groove. There are pressing plates arranged at intervals in the installation groove. The pressing plates are provided with first connection holes, and the connection base body is provided with second connection holes. The first connection holes and the second connection holes are arranged in one-to-one correspondence. An adjusting member is arranged between adjacent pressing plates. The adjusting member includes a first ring plate and a second ring plate. The first ring plate and the second ring plate respectively abut against adjacent pressing plates. An elastic plate is arranged between the first ring plate and the second ring plate.

[0007] According to an embodiment of the present invention, the pressing plate is inclined. The pressing plate has a back surface facing the mounting groove and a front surface on the other side. The first ring plate is connected to the back surface of the pressing plate on one side. The second ring plate is bent and includes a first surface and a second surface. The first surface abuts against the front surface of the pressing plate on the other side, and the second surface abuts against the mounting groove.

[0008] The panel lamp is connected to the fixed surface by using a connecting base. It should be noted that the fixed surface can be the surface of a fixed base such as a wall surface, or a frame such as a lamp holder that can be moved to adjust the angle and height of the panel lamp. The fixed surface, the housing connection structure, and the panel lamp can be sequentially connected by fasteners. When the fasteners pass through the housing connection structure, they are sequentially connected through the first connection holes provided on the pressing plate and the second connection holes provided on the connecting base.

[0009] Since the pressing plate is inclined and an adjusting member is provided between two adjacent pressing plates, the cooperation between the pressing plate and the fastener actually has a tensioning effect on the fastener to prevent the fastener from loosening. It should be noted that when the fastener passes through the connection structure to connect the fixed surface and the panel lamp, the pressing plate will be compressed at this time, and the adjusting member will be compressed. An elastic plate provided between the first ring plate and the second ring plate of the adjusting member will undergo elastic deformation, the distance between the first annular plate and the first surface will decrease, the inclination angle of the pressing plate will increase, and the distance between the pressing plates will decrease. At this time, the adjusting member will apply an upward force to the adjacent pressing plate, and the pressing plate will transfer this force to the fastener, thereby realizing the action of this tensioning force on the fastener to prevent the fastener from loosening; in addition, through the setting of the adjusting member, when the panel lamp or the fixed surface vibrates, through the setting of the adjusting member provided between the two pressing plates, the vibration can be prevented from being transmitted, that is, the vibration of the panel lamp is prevented from being transmitted to the fixed surface or the vibration of the vibrating surface is prevented from being transmitted to the panel lamp, which can improve the stability of the panel lamp, reduce the vibration amplitude of the panel lamp and accelerate the speed of the panel lamp to stabilize, and when it is necessary to move or adjust the angle of the frame, the adjusting member can prevent the panel lamp from vibrating too much and causing the connection between the fixed surface and the panel lamp to be unstable.

[0010] Through the arrangement of the array with the pressing plate and the adjusting member, when adjusting the fastener, the distance between the panel light and the fixing surface can be adjusted. Since there are multiple fasteners, the accuracy and stability of the distance adjustment between the panel light and the fixing surface can be achieved. There can be a spacing distance between the panel light and the fixing surface to provide a heat dissipation space between the panel light and the fixing surface. Moreover, when the air flow passes through the connecting structure, during the process of passing through the pressing plate and the adjusting member, the air flow will be disturbed by the shape of the adjusting member, thereby improving the contact effect between the air flow and the connecting matrix, and improving the heat dissipation effect of the panel light. In addition, the turbulent flow formed after the air flow is disturbed by the adjusting member and the pressing plate is beneficial to cleaning the dust at the connection of the panel light, preventing excessive dust accumulation from causing the panel light to easily accumulate too much heat and unable to dissipate.

[0011] Furthermore, there are no less than two limiting plates between the first ring plate and the second ring plate. The limiting plate is a flexible plate, which can be arranged on the first ring plate or the second ring plate. The limiting plate is used to prevent the elastic plate between the first ring plate and the second ring plate from bending too much when the fastener applies too much force on the pressing plate, resulting in exceeding the yield limit of the elastic plate. In addition, the setting of the limiting plate can further realize the disturbance of the air flow, improve the air flow situation near the connecting structure, and improve the heat dissipation effect of the panel light.

[0012] Furthermore, the fasteners can be arranged at intervals. Specifically, the cooperation between the pressing plate and the fasteners is not one-to-one. The cooperation between the fasteners and the pressing plate can be arranged at intervals. Through the setting of the fasteners, the distribution of the fasteners can be realized as needed, that is, different fastener arrangement methods can be adopted for different fixing surfaces and different panel lights. It should be noted that the interval arrangement of the fasteners can also realize the functions of the pressing plate and the adjusting member, and improve the adaptability of the connecting structure.

[0013] According to an embodiment of the present invention, convex strips are provided on both the first surface and the second surface.

[0014] The first ring plate is connected to the back of the pressing plate on one side. The convex strip provided on the first surface is used to abut against the front surface of the pressing plate, and the convex strip provided on the second surface is used to abut against the inner surface of the installation groove. Specifically, the first ring plate and the back of the pressing plate on one side are fixedly connected, and the convex strip is slidably connected to the surfaces of the pressing plate and the installation groove. Such a setting can improve the connection strength between the adjusting member and the pressing plate, and also improve the regulation between the first ring plate and the second ring plate. In addition, the setting of the convex strip can further improve the heat dissipation performance of the connecting structure, that is, the convex strip located on the second surface can dissipate heat through the air flow.

[0015] The panel light includes a first base body, and there is no less than one connecting groove provided on the first base body. It also includes a housing connecting structure of the panel light, and the connecting matrix is arranged in one-to-one correspondence with the connecting groove.

[0016] According to an embodiment of the present invention, the first substrate and the connection groove are provided with protrusions on the opposite side, a bent diffusion plate is provided between the two protrusions, a lamp board is provided on one side of the diffusion plate, and there are no less than two lamp beads on the lamp board;

[0017] Mounting side plates are provided on both sides of the first base body, lamp shades are provided at intervals on one side of the lamp board, and the lamp shades are connected to the protrusions.

[0018] The present invention further designs the panel light. As described above, two opposite protrusions are provided on one side of the first substrate, and there is a bent diffusion plate between the protrusions. A lamp board is provided on the diffusion plate, and the light emitted by the lamp beads on the lamp board is irradiated and the light emitted by the lamp beads will be diffused under the refraction of the diffusion plate.

[0019] The lamp shade is used to protect the lamp board and prevent the occurrence of short circuits caused by organisms entering.

[0020] Furthermore, a second substrate that is detachably connected and perpendicular to the first substrate is provided on the first substrate. A connection groove is also provided on the second substrate, and the installation groove is used to cooperate with the connection base body. The setting of the second substrate is used to expand the application range of the panel light. In addition, a connection groove is provided on the second substrate and the connection groove can cooperate with the connection base body, which can also improve the stability of the second substrate during the fixing process.

[0021] According to an embodiment of the present invention, the lamp shade includes a first lamp shade and a second lamp shade that are spaced apart inside and outside, and ventilation holes are arranged on the second lamp shade.

[0022] Through the above design, by arranging ventilation holes on the second lamp shade, the temperature of the internal space of the first lamp shade can be dissipated, and through the setting of the first lamp shade and the second lamp shade, the light will be refracted by the two side covers, and the light distribution can be made more uniform and the diffusion range can be larger. Furthermore, the ventilation holes on the second lamp shade are arranged around the side, and the ventilation holes can refract the light from the first lamp shade and emit it, further expanding the light irradiation effect around the lamp shade, that is, reducing the problem of insufficient light irradiation in the range of the connection position between the panel light and the fixing surface.

Specific embodiments

[0034] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments and the accompanying drawings:

[0035] Embodiment 1:

[0036] As Figures 1-9 shown, the housing connection structure of the panel light includes a connecting base body 1. One side of the connecting base body 1 has a mounting groove 11. Inside the mounting groove 11, there are pressing plates 12 arranged at intervals. The pressing plate 12 is provided with a first connection hole 13, and the connecting base body 1 is provided with a second connection hole 14. The first connection hole 13 and the second connection hole 14 are arranged in one-to-one correspondence. An adjusting part 2 is arranged between adjacent pressing plates 12. The adjusting part 2 includes a first ring plate 21 and a second ring plate 22. The first ring plate 21 and the second ring plate 22 are respectively in contact with adjacent pressing plates 12, and an elastic plate 23 is arranged between the first ring plate 21 and the second ring plate 22.

[0037] The pressing plate 12 is inclined. The pressing plate 12 has a back surface facing the mounting groove 11 and a front surface on the other side. The first ring plate 21 is connected to the back surface of one side of the pressing plate 12. The second ring plate 22 is bent. The second ring plate 22 includes a first surface 24 and a second surface 25. The first surface 24 is in contact with the front surface of the pressing plate 12 on the other side, and the second surface 25 is in contact with the mounting groove 11.

[0038] The panel light is connected to the fixed surface by using the connecting base 1. It should be noted that the fixed surface can be the surface of a fixed base such as a wall surface, or a frame such as a lamp holder that can be moved to adjust the angle and height of the panel light, etc. The fastener 5 can sequentially connect the fixed surface, the housing connection structure, and the panel light. When the fastener 5 passes through the housing connection structure, it sequentially passes through the first connection hole 13 provided on the pressure plate 12 and the second connection hole 14 provided on the connecting base 1.

[0039] Since the pressure plate 12 is inclined, and an adjusting member 2 is provided between two adjacent pressure plates 12, the cooperation between the pressure plate 12 and the fastener 5 actually has a tensioning effect on the fastener 5 to prevent the fastener 5 from loosening. It should be noted that when the fastener 5 passes through the connection structure to connect the fixed surface and the panel light, the pressure plate 12 will be compressed at this time. At this time, the adjusting member 2 will be compressed, and the elastic plate 23 provided between the first ring plate 21 and the second ring plate 22 of the adjusting member 2 will undergo elastic deformation, and the distance between the first annular plate and the first surface 24 will decrease, the inclination angle of the pressure plate 12 will increase, and the distance between the pressure plates 12 will decrease. The adjusting member 2 will apply an upward force to the adjacent pressure plate 12, and the pressure plate 12 will transfer this force to the fastener 5, thereby realizing the action of this tensioning force on the fastener 5 to prevent the fastener 5 from loosening; in addition, through the setting of the adjusting member 2, when the panel light or the fixed surface vibrates, through the setting of the adjusting member 2 provided between the two pressure plates 12, the vibration transmission can be prevented, that is, the vibration of the panel light is prevented from being transmitted to the fixed surface or the vibration of the vibration surface is prevented from being transmitted to the panel light, which can improve the stability of the panel light, reduce the vibration amplitude of the panel light and accelerate the speed of the panel light to stabilize, and when it is necessary to move or adjust the angle of the frame, through the adjusting member 2, it can prevent the situation that the connection between the fixed surface and the panel light becomes unstable due to excessive vibration of the panel light.

[0040] By arranging the pressure plates 12 and the adjusting members 2 in an array, when adjusting the fastener 5, the distance between the panel light and the fixed surface can be adjusted. Since there are multiple fasteners 5, the accuracy and stability of the distance adjustment between the panel light and the fixed surface can be realized, and an interval distance can be provided between the panel light and the fixed surface to form a heat dissipation space between the panel light and the fixed surface. And when the air flow passes through the connection structure, when the air flow passes through the pressure plates 12 and the adjusting members 2, it will be interfered by the shape of the adjusting member 2 itself, thereby improving the contact effect between the air flow and the connecting base 1, which can improve the heat dissipation effect of the panel light. In addition, the turbulent flow formed after the air flow is interfered by the adjusting member 2 and the pressure plate 12 is beneficial to cleaning the dust at the connection of the panel light, preventing excessive dust accumulation from causing the panel light to accumulate too much heat and unable to dissipate.

[0041] Furthermore, there are at least two limiting plates between the first ring plate 21 and the second ring plate 22. The limiting plates are flexible plates, which can be arranged on the first ring plate 21 or the second ring plate 22. The limiting plates are used to prevent the elastic plate 23 between the first ring plate 21 and the second ring plate 22 from bending too much when an excessive force is applied to the pressing plate 12 by the fastener 5, resulting in exceeding the yield limit of the elastic plate 23. In addition, the arrangement of the limiting plates can further realize the disturbance of the air flow, improve the air flow condition near the connection structure, and improve the heat dissipation effect of the panel light.

[0042] Furthermore, the fasteners 5 can be arranged at intervals. Specifically, the cooperation between the pressing plate 12 and the fasteners 5 is not set in a one-to-one correspondence. The cooperation between the fasteners 5 and the pressing plate 12 can be arranged at intervals. By setting the fasteners 5, the distribution of the fasteners 5 can be realized as needed, that is, different distribution methods of the fasteners 5 can be adopted for different fixing surfaces and different panel lights. It should be noted that the arrangement of the fasteners 5 at intervals can also realize the functions of the pressing plate 12 and the adjusting member 2, and can improve the adaptability of the connection structure.

[0043] Ribs 26 are provided on both the first surface 24 and the second surface 25.

[0044] The first ring plate 21 is connected to the back surface of one side of the pressing plate 12. The rib 26 provided on the first surface 24 is used to abut against the front surface of the pressing plate 12, and the rib 26 provided on the second surface 25 is used to abut against the inner surface of the installation groove 11. Specifically, the first ring plate 21 and the back surface of one side of the pressing plate 12 are fixedly connected, and the rib 26 is slidably connected to the surfaces of the pressing plate 12 and the installation groove 11. Such an arrangement can improve the connection strength between the adjusting member 2 and the pressing plate 12, and can also improve the regulation between the first ring plate 21 and the second ring plate 22. In addition, the arrangement of the rib 26 can further improve the heat dissipation performance of the connection structure, that is, the rib 26 located on the second surface 25 can dissipate heat through the air flow.

[0048] The present invention further designs the panel light. As described above, two opposite protrusions 33 are provided on one side of the first substrate 32, and a bent diffusion plate 34 is provided between the protrusions 33. A lamp board 35 is provided on the diffusion plate 34. The light emitted by the lamp beads 36 on the lamp board 35 is irradiated and diffused under the refraction of the diffusion plate 34, so that the light of the panel light is controlled within a set irradiation angle range; the installation side plate 37 and the protrusions 33 together fix the lamp cover 4, and the installation side plate 37, the protrusions 33 and the lamp cover 4 together protect the lamp board 35 to prevent the occurrence of short circuits caused by organisms entering. The diffusion plate 34 between the two protrusions 33 is arranged in contact with the protrusions 33, so the protrusions 33 can control the light refraction angle of the diffusion plate 34.

[0049] Furthermore, the protrusion 33 is a hollow structure. The hollow structure of the protrusion 33 can increase the heat dissipation area of the panel light and improve the heat dissipation effect of the panel light.

[0050] Furthermore, a second substrate detachably connected and perpendicular to the first substrate 32 is provided on the first substrate 32. A connection groove 31 is also provided on the second substrate, and the installation groove 11 is used to cooperate with the connection base 1. The setting of the second substrate is used to expand the application range of the panel light. In addition, a connection groove 31 is provided on the second substrate and the connection groove 31 can cooperate with the connection base 1, which can also improve the stability of the second substrate during the fixing process.

[0051] The lamp cover 4 includes a first lamp cover 41 and a second lamp cover 42 arranged at intervals inside and outside, and ventilation holes 43 are arranged on the second lamp cover 42.

[0052] Through the above design, the temperature of the internal space of the first lamp cover 41 can be dissipated by arranging the ventilation holes 43 on the second lamp cover 42, and the light will be refracted by the two lamp covers by setting the first lamp cover 41 and the second lamp cover 42, so that the light distribution can be more uniform and the diffusion range can be larger. Furthermore, the ventilation holes 43 on the second lamp cover 42 are arranged around the side, and the ventilation holes 43 can refract the light from the first lamp cover 41, further expanding the light irradiation effect around the lamp cover 4, that is, reducing the problem that the light at the connection position between the panel light and the fixing surface is not in place.

Moreover, the setting of the fitting 6 can improve the contact firmness between the fastener 5 and the diffusion plate 34 and ensure the parallel effect between the lamp board 35 and the first base body 3 in the installed state. Because the first fitting ring 62 and the second fitting ring of the fitting 6 can adjust the horizontal state of the lamp board 35 to ensure the horizontality of the lamp board 35 and avoid loosening of the lamp board 35 relative to the fastener 5.
