[0046] like Figures 1 to 7 As shown, the ceiling lamp housing 100, LED lamp board 20, lens 30, driver 50 and heat-conducting member 60 provided in the embodiment of the present application. The housing 100 includes a lamp housing 10 and a housing cover 40. The lamp housing 10 forms a receiving space 12 with a light outlet 11. The housing cover 40 is connected to the back side 13 of the lamp housing 10 away from the receiving space 12. A first sealing ring 44 is provided between the circumferential edge area of ​​the housing cover 40 and the back side 13, so that a sealing arrangement is achieved between the housing cover 40 and the back side 13. The LED lamp board 20 is connected to the lamp housing 10 and is located in the receiving space 12. The lens 30 is installed at the light outlet 11. A second sealing ring 31 is provided between the circumferential edge area of ​​the lens 30 and the circumferential edge area of ​​the light outlet 11, so that a sealing arrangement is achieved between the lens 30 and the lamp housing 10. After the LED lamp board 20 is turned on, light is irradiated to the lens 30, and the light is adjusted by the lens 30 and transmitted to illuminate. The driver 50 is disposed in the shell cover 40, the driver 50 is electrically connected to the LED light board 20, the driver 50 is electrically connected to the external circuit, and the driver 50 is turned on to supply power to the LED light board 20. In the ceiling lamp, the heat-conducting member 60 is connected to the back side 13 of the lamp housing 10 and is located in the shell cover 40, wherein the heat-conducting member 60 includes a first rib plate structure 61, the first rib plate structure 61 has a first side wall 611 and a second side wall 612 opposite to each other, the first rib plate structure 61 is located between the side wall of the driver 50 and the inner wall of the shell cover 40, and the first side wall 611 is in contact with the side wall of the driver 50, and the second side wall 612 is in contact with the inner wall of the shell cover 40.

[0047] The ceiling lamp provided by the present application is used for lighting, the driver 50 is turned on and controls the LED lamp board 20 to start, the LED lamp board 20 emits light to the lens 30 located at the light outlet 11 of the lamp housing 10, and the light is adjusted by the lens 30 and then transmitted for lighting. In the process of lighting by the ceiling lamp, in order to effectively transfer the heat generated by the driver 50 to the housing 100 to dissipate into the air, the ceiling lamp of the present application is provided with a heat-conducting member 60, wherein the heat-conducting member 60 includes a first rib plate structure 61, the first rib plate structure 61 is located between the side wall of the driver 50 and the inner wall of the housing cover 40, and the first side wall 611 of the first rib plate structure 61 is in contact with the side wall of the driver 50, and the second side wall 612 of the first rib plate structure 61 is in contact with the inner wall of the housing cover 40, so that the air gap between the side wall of the driver 50 and the inner wall of the housing cover 40 is eliminated by the first rib plate structure 61, thereby eliminating the air gap thermal resistance. In this way, the heat generated by the driver 50 can be quickly transferred to the first rib structure 61, and the first rib structure 61 quickly transfers the heat to the shell cover 40, the outer wall of the shell cover 40 is exposed to the ambient air, and then the shell cover 40 dissipates the heat into the air, thereby greatly improving the heat transfer efficiency between the driver 50 and the shell cover 40, and improving the overall heat dissipation efficiency of the ceiling light.

[0048] In the ceiling lamp of the related art, due to the air gap thermal resistance between the side wall of the driver 50 and the inner wall of the shell cover 40, the heat generated by the driver 50 is transferred to the shell cover 40 through air radiation, and in order to meet the requirement of rapid heat dissipation, a plurality of heat dissipation fins are arranged on the outer wall of the shell cover 40 corresponding to the driver 50. Although the heat dissipation efficiency is improved to a certain extent by the heat dissipation fins, the improvement of the heat dissipation efficiency is limited, and these exposed heat dissipation fins make the appearance of the ceiling lamp not simple, and the gap between two adjacent heat dissipation fins is easy to hide dirt and is difficult to clean. In this regard, the ceiling lamp provided in the embodiment of the present application uses a heat-conducting member 60, so that the first side wall 611 of the first rib structure 61 of the heat-conducting member 60 is fitted with the side wall of the driver 50, and the second side wall 612 of the first rib structure 61 is fitted with the inner wall of the shell cover 40, thereby eliminating the air gap thermal resistance between the side wall of the driver 50 and the inner wall of the shell cover 40, so that the heat generated by the driver 50 can be quickly transferred to the shell cover 40 and then dissipated into the air. Therefore, as 1, Figure 2 and Fig.10 As shown, the outer wall of the shell cover 40 of the ceiling lamp provided in the embodiment of the present application can meet the requirement of rapid heat dissipation even if the heat dissipation fins are removed, so that the outer wall of the shell cover 40 can be designed to be smooth and simple, so that the outer wall of the shell cover 40 can be easily cleaned even if dust accumulates.

[0049] like Figure 5 and Figure 6As shown, the heat-conducting member 60 further includes a bottom plate 62, which is locked to the back side 13 of the lamp housing 10 by screws, and the bottom plate 62 is attached to the back side 13. In addition, the first rib structure 61 is arranged on the bottom plate 62, and the bottom side of the driver 50 is attached to the bottom plate 62. In this way, of the heat generated by the driver 50, part of the heat is transferred to the shell cover 40 by the first rib structure 61, and is dissipated into the air by the shell cover 40, and part of the heat is transferred to the lamp housing 10 by the bottom plate 62, and is dissipated into the air by the outer wall of the lamp housing 10 exposed to the air. In this way, the heat dissipation efficiency of the driver 50 can be further improved, thereby improving the heat dissipation efficiency of the ceiling lamp as a whole.

[0050] Further, such as Figure 5 and Figure 6 As shown, there are two first rib structures 61, which are connected to the bottom plate 62 oppositely and at intervals, and the two first rib structures 61 clamp the driver 50. That is, the two first rib structures 61 simultaneously transfer the heat generated by the driver 50 to the shell cover 40, and then the shell cover 40 dissipates the heat into the air, thereby further improving the heat transfer efficiency between the driver 50 and the shell cover 40, and then improving the overall heat dissipation efficiency of the ceiling lamp.

[0051] The ceiling lamp provided in the embodiment of the present application is a lamp capable of realizing remote control. Therefore, the driver 50 of the ceiling lamp includes a power supply driver, a control driver, etc., and as Figures 1 to 4 As shown in FIG. 1 , the ceiling lamp is provided with an antenna 81 for receiving control signals. The antenna 81 is electrically connected to the control driver. The antenna 81 is locked on the housing cover 40 by a nut 82. In order to assemble the driver 50 such as the power supply driver and the control driver, as shown in FIG. Figure 5 and Figure 6 As shown, the heat-conducting member 60 further includes a second rib plate structure 63, which is connected to the bottom plate 62 and is located between the two first rib plate structures 61. The second rib plate structure 63 is used to separate at least two placement spaces 64 between the two first rib plate structures 61, and one placement space 64 is used to place one driver 50, and the side wall of the second rib plate structure 63 is attached to the side wall of the driver 50. In this way, the first rib plate structure 61, the second rib plate structure 63 and the bottom plate 62 simultaneously transfer the heat generated by the driver 50 to the housing 100, and then the outer side wall of the housing 100 exposed to the air dissipates the heat into the air, thereby improving the heat dissipation efficiency.

[0052] In the ceiling lamp of the embodiment of the present application, the heat-conducting member 60 is an integrally formed component. Preferably, the heat-conducting member 60 is an aluminum profile member prepared by an extrusion process, which has high assembly strength and good thermal conductivity, and the aluminum material is light in weight, which helps to reduce the overall weight of the ceiling lamp. Furthermore, the lamp housing 10 and the housing cover 40 are both made of aluminum material, and cooperate with the aluminum heat-conducting member 60 to achieve efficient heat conduction effect and further reduce the overall weight of the ceiling lamp.

[0053] like Figure 5 and Figure 6 As shown, along the direction from the shell cover 40 to the lamp housing 10, the second side wall 612 is inclined relative to the first side wall 611 and gradually moves away. In this ceiling lamp, the shell cover 40 is a casting. In order to facilitate demoulding, the inner wall of the shell cover 40 is set to a wall surface with an inclination. In this way, the first side wall 611 of the inclined first rib plate structure 61 matches the inner wall of the shell cover 40 with an inclination, so that the first side wall 611 is closely attached to the inner wall of the shell cover 40, ensuring the heat conduction efficiency between the first rib plate structure 61 and the shell cover 40.

[0054] In the process of using the ceiling lamp for lighting, the LED lamp board 20 also generates heat. In order to effectively transfer the heat generated by the LED lamp board 20 to the housing 100 and finally dissipate it into the air, Figure 4 , Figure 8 and Fig. 9 As shown, the bottom wall of the accommodating space 12 of the lamp housing 10 is provided with a heat-conducting structure 14, which abuts against the LED lamp board 20, and the heat-conducting structure 14 corresponds to the portion of the back side 13 of the lamp housing 10 exposed to the air. In this way, the heat generated by the LED lamp board 20 can be quickly transferred from the heat-conducting structure 14 to the lamp housing 10, and the heat is dissipated into the air from the portion of the back side 13 of the lamp housing 10 exposed to the air, thereby achieving the purpose of heat dissipation for the LED lamp board 20.

[0055] Specifically, Fig. 9 As shown, the heat-conducting structure 14 includes a plurality of heat-conducting columns 141 and a plurality of connecting ribs 142. The plurality of heat-conducting columns 141 are arranged in an array, and the top ends of the heat-conducting columns 141 abut against the LED light board 20, so that the heat generated by the LED light board 20 can be efficiently transferred to the lamp housing 10. In addition, the two ends of the connecting rib 142 are respectively connected to two adjacent heat-conducting columns 141, so that the plurality of heat-conducting columns 141 are mutually related and cooperated to transfer the heat generated by the LED light board 20 to the lamp housing 10. In addition, the plurality of connecting ribs 142 connect the plurality of heat-conducting columns 141 to each other, which helps to improve the overall strength of the lamp housing 10.

[0056] like Figure 1 , Figure 2 , Figure 5 , Fig.10 and Fig.11 As shown, a connecting protrusion 41 is provided on the side of the housing cover 40 away from the lamp housing 10, and the ceiling lamp further comprises a mounting assembly 70, which is detachably connected to the connecting protrusion 41 and is used to be connected to the ceiling. Figure 2 and Figure 4 As shown, the mounting assembly 70 includes a hanging member 71, an adapter 72, a first connecting bolt 73 and a second connecting bolt 74. The adapter 72 is locked on the connecting protrusion 41 by the second connecting bolt 74 (i.e., the second connecting bolt 74 is threadedly connected to the threaded hole of the connecting protrusion 41, thereby locking the adapter 72). The adapter 72 is provided with a limiting protrusion 721, and the connecting protrusion 41 is provided with a limiting groove 411 corresponding to the limiting protrusion 721. When the adapter 72 is placed on the connecting protrusion 41, the limiting protrusion 721 is inserted into the limiting groove 411, so that the adapter 72 is quickly positioned and placed on the connecting protrusion 41. When the second connecting bolt 74 is tightened, the connecting protrusion 41 is provided with a locking screw hole 412, and the locking screw 75 is threaded into the locking screw hole 412, and the end of the locking screw 75 abuts against the second connecting bolt 74, thereby locking the second connecting bolt 74. The hanging member 71 is U-shaped, and the two ends of the hanging member 71 are respectively connected to the two ends of the adapter 72 through the first connecting bolts 73. The two first connecting bolts 73 are coaxially arranged. The hanging member 71 can rotate relative to the adapter 72 with the axis of the first connecting bolts 73 as the rotation axis, so as to adjust the lighting angle of the ceiling light.

[0057] In other embodiments of the present application, the mounting assembly 70 may also directly adopt a hook member, and an external thread is directly set at one end of the hook member, so that it is directly screwed into the threaded hole of the connecting protrusion 41, and then screwed into the locking screw hole 412 through the locking screw 75 to lock the hook member.

[0058] Further, such as Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, a connecting rib 42 is further provided on the side of the housing cover 40 away from the lamp housing 10, and the connecting rib 42 is connected to the outer side wall of the connecting protrusion 41, and a connecting hole 43 for connecting a safety rope is provided on the connecting rib 42. By connecting the installation rope to the connecting rib 42 and connecting the safety rope to the ceiling, when the installation assembly 70 fails, the safety rope can prevent the ceiling lamp from falling directly and injuring people passing by.

[0059] In the ceiling lamp of the embodiment of the present application, the outer contour of the connecting protrusion 41 along the direction from the lamp housing 10 to the shell cover 40 is in the shape of a cone. In this way, when casting the shell cover 40, the cast shell cover 40 can be easily demolded. The connecting protrusion 41 can be a solid protrusion or a hollow protrusion. In the embodiment of the present application, in order to reduce the weight of the shell cover 40, a hollow protrusion is preferably used, and in order to ensure the strength of the connecting protrusion 41, a reinforcing rib 413 is designed, such as Fig.12 As shown, the plurality of reinforcing ribs 413 are evenly spaced apart circumferentially.

[0060] 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.
