[0050] Embodiment 1:

[0051] like Figures 1 to 5As shown, the LED lamp provided in the first embodiment of the present application includes a lamp housing 10, a columnar lamp holder 20, a cylindrical light-emitting shell 50, a driving circuit board 60, a plurality of electrode terminals 61 and a plurality of first LED light sources 30, and the LED lamp also includes a second LED light source 40. The lamp housing 10 is provided with a plug-in end 13, the plug-in end 13 is used to be plugged into the lamp holder, and the side wall of the plug-in end 13 is provided with an anti-detachment protrusion 131, when the plug-in end 13 is inserted into the lamp holder, the anti-detachment protrusion 131 is stuck in the anti-detachment groove of the lamp holder, thereby preventing the plug-in end 13 from being separated from the lamp holder at will. The plurality of electrode terminals 61 are all connected to the lamp housing 10, and the plurality of electrode terminals 61 pass through the lamp housing 10 along the axial direction of the plug-in end 13, and are spaced around the plug-in end 13. The first end of the columnar lamp holder 20 is connected to the end of the lamp housing 10 away from the plug-in end 13, the cross-sectional profile of the columnar lamp holder 20 is a regular polygon, and the columnar lamp holder 20 is formed with a hollow cavity 21. The driving circuit board 60 is accommodated in the hollow cavity 21, and the driving circuit board 60 is electrically connected to the electrode terminal 61. A plurality of first LED light sources 30 are arranged on a plurality of side walls of the columnar lamp holder 20 in a one-to-one correspondence, and the driving circuit board 60 is electrically connected to the first LED light source 30. The second LED light source 40 is arranged at the second end of the columnar lamp holder 20, and the driving circuit board 60 is electrically connected to the second LED light source 40. The cylindrical light emitting shell 50 is sleeved on the columnar lamp holder 20, the first end of the cylindrical light emitting shell 50 is connected to the lamp holder housing 10, and the second end of the cylindrical light emitting shell 50 is connected to the second end of the columnar lamp holder 20.

[0052] In the LED lamp provided by the present application, a plurality of first LED light sources 30 are circumferentially arranged one by one on the side wall of a columnar lamp holder 20 whose cross-sectional profile is a regular polygon, and a second LED light source 40 is arranged at the second end of the columnar lamp holder 20 away from the lamp holder housing 10, and the columnar lamp holder 20 is covered by a cylindrical light-emitting shell 50. When the LED lamp provided by the present application is used for lighting, the plug-in end 13 of the lamp holder housing 10 is inserted into the lamp holder, so that the electrode terminal 61 is connected to the external circuit, and then the driving circuit board 60 is turned on and outputs a direct current to the first LED light source 30 and the second LED light source 40 after rectification and adjustment, so that the first LED light source 30 and the second LED light source 40 are powered on and emit light at the same time, and the light emitted by the first LED light source 30 is emitted from the circumferential side wall of the cylindrical light-emitting shell 50 for illumination, and the light emitted by the second LED light source 40 is emitted from the second end of the cylindrical light-emitting shell 50 away from the lamp holder housing 10 for illumination. In this way, the LED lamp forms a lighting effect with a 360° beam angle light output, which can meet the requirements of large beam angle light output at the lighting site. Moreover, compared with the fluorescent lamp of the related art, the LED lamp consumes less energy and has better energy-saving effect.

[0053] In the LED lamp of the first embodiment of the present application, the first end of the columnar lamp holder 20 is detachably connected to the end of the lamp housing 10 away from the plug-in end 13 by a first screw 81. In this way, the columnar lamp holder 20 and the lamp housing 10 cannot be disassembled at will by the user, but the first screw 81 needs to be disassembled with the assistance of a screwdriver or other tools, and then the driving circuit board 60, the first LED light source 30, the second LED light source 40, etc. can be repaired or replaced, thereby eliminating the safety hazard caused by the user's arbitrary disassembly of the LED lamp and protecting the user's safety in using the LED lamp.

[0054] like Figure 5 As shown, the inner wall of the hollow cavity 21 is provided with a first card slot 211 and a second card slot 212 opposite to each other. The driving circuit board 60 is a rectangular plate, and the two side edges of the driving circuit board 60 are respectively inserted into the first card slot 211 and the second card slot 212, so that the driving circuit board 60 can be conveniently and quickly installed in the hollow cavity 21 of the columnar lamp holder 20.

[0055] like Figure 4 and Figure 5 As shown, the two side edges of each side wall of the columnar lamp holder 20 are respectively provided with a first buckle edge 22 and a second buckle edge 23, and the first buckle edge 22 and the second buckle edge 23 are arranged opposite to each other. In addition, the first buckle edge 22 forms a third card slot 221 with the corresponding side wall, and the second buckle edge 23 forms a fourth card slot 231 with the corresponding side wall. When installing multiple first LED light sources 30, the multiple first LED light sources 30 correspond to the multiple side walls one by one, and the substrate of each first LED light source 30 is a rectangular plate, and the two side edges of the substrate of each first LED light source 30 are respectively inserted into the third card slot 221 and the fourth card slot 231. In this way, multiple first LED light sources 30 can be installed conveniently and quickly, thereby improving assembly efficiency.

[0056] In the first embodiment of the present application, the columnar lamp holder 20 is an integrally formed component, wherein the columnar lamp holder 20 is an aluminum profile formed by extrusion process using aluminum material, which is conducive to heat conduction and heat dissipation of the heat generated by the plurality of first LED light sources 30 when emitting light.

[0057] like Figures 1 to 3 As shown, the LED lamp further includes a control switch 70, which is mounted on the lamp housing 10 and electrically connected to the driving circuit board 60. The user can not only control the on and off of the LED lamp through the control switch 70, but also select different color temperature ranges of the LED lamp through the control switch 70, so that the LED lamp can adapt to different needs of various lighting scenes, making the LED lamp more widely used.

[0058] Furthermore, the configuration of the plug end 13 and the plurality of electrode terminals 61 conforms to the G24, GX24 or GY24 lamp holder specifications specified in the IEC 60061 standard. IEC 60061 is a standard established by the International Electrotechnical Commission (IEC) that specifies the specifications and dimensions of electric lamps and lamps.

[0059] like Figure 2 and Figure 3 As shown, the cylindrical light-emitting shell 50 includes a cylindrical shell 51 and an end cover 52. The cylindrical shell 51 is sleeved on the columnar lamp holder 20, and the first LED light source 30 is located between the cylindrical shell 51 and the columnar lamp holder 20. Specifically, the first end of the cylindrical shell 51 is docked with the lamp holder housing 10, and the end cover 52 is covered on the second end of the cylindrical shell 51. The second LED light source 40 is located between the second end of the columnar lamp holder 20 and the end cover 52, and the end cover 52 is detachably connected to the second end of the columnar lamp holder 20. In other words, the cylindrical shell 51 is clamped and fixed by the lamp holder housing 10 and the end cover 52. When the LED lamp is illuminated, the first LED light source 30 emits light to the cylindrical shell 51 and emits light for illumination, and the second LED light source 40 emits light to the end cover 52 and emits light for illumination. In this way, the entire cylindrical light-emitting shell 50 emits light for illumination, forming a lighting effect with a 360° beam angle light output, which can meet the requirements of large beam angle light output at the lighting scene.

[0060] The cylindrical shell 51 and the end cover 52 are both set to be in a semi-transparent state in an atomized form. In this way, after the cylindrical light-emitting shell 50 is assembled, the columnar lamp holder 20, the first LED light source 30, the second LED light source 40, etc. in the cylindrical light-emitting shell 50 will not be directly visible to the user, and the semi-transparent cylindrical light-emitting shell 50 in an atomized form is conducive to uniform and soft light emission, which is not dazzling to the user's eyes.

[0061] like Figure 2 and Figure 3 As shown, in the LED lamp of the first embodiment of the present application, the end cover 52 is locked to the second end of the columnar lamp holder 20 by a second screw 82 .

[0062] In the LED lamp of the first embodiment of the present application, Figures 1 to 3As shown, the cross-sectional profile of the columnar lamp holder 20 is a regular hexagon, and the cylinder shell 51 is cylindrical. In other embodiments, when the cylinder shell 51 is cylindrical, the cross-sectional profile of the columnar lamp holder 20 can also be an equilateral triangle, a square, a regular pentagon, a regular heptagon, etc., which are not limited here. The cross-sectional profile of the columnar lamp holder 20 of the LED lamp of the first embodiment of the present application is preferably a regular hexagon, which is not only conducive to the circumferential uniform light emission of the cylinder shell 51, and realizes circumferential uniform and soft light illumination, but also is conducive to the reasonable configuration of the number of the first LED light sources 30 and the convenient configuration of the size of the first LED light source 30, so as to facilitate assembly.

[0063] like Figure 2 and Figure 3 As shown, since the tube shell 51 of the LED lamp of the first embodiment of the present application is cylindrical, and the main part of the lamp holder housing 10 is a square structure, in order to enable the main part of the lamp holder housing 10 to be adaptively docked with the tube shell 51, the lamp holder housing 10 includes a first shell 11 and a second shell 12, the first shell 11 is connected to the first end of the columnar lamp holder 20, the first end of the tube shell 51 is docked with the first shell 11, the second shell 12 is connected to the side of the first shell 11 away from the columnar lamp holder 20, and the end of the second shell 12 away from the first shell 11 is provided with a plug-in terminal 13, and the electrode terminal 61 passes through the second shell 12. In the LED lamp of the first embodiment of the present application, the second shell 12 is the main part of the square structure of the lamp holder housing 10, and the first shell 11 is a transition component between the second shell 12 and the cylindrical tube shell 51, so as to facilitate assembly and improve assembly efficiency. That is, the end of the first shell 11 that is connected to the end of the cylindrical shell 51 is an adaptive cylindrical shape, and the end of the first shell 11 that is connected to the second shell 12 is a square structure. In addition, the first shell 11 is locked and connected to the first end of the columnar lamp holder 20 by screws.

[0064] Embodiment 2:

[0065] Compared with the LED lamp provided in the first embodiment, the LED lamp provided in the second embodiment has the following differences.

[0066] In the LED lamp of the second embodiment of the present application, Figures 6 to 12As shown, the cross-sectional profile of the columnar lamp holder 20 is a square. Correspondingly, the cross-sectional profile of the cylinder shell 51 is a square, and an arc transition area 511 is formed between two adjacent side walls of the cylinder shell 51. When the cylinder shell 51 is sleeved on the columnar lamp holder 20, the four arc transition areas 511 are arranged opposite to the first LED light sources 30 on the four side walls of the columnar lamp holder 20. At this time, the four arc transition areas 511 are all main light emitting areas. In this way, it is possible to avoid the situation where four shadow spots are generated when the four edges of the columnar lamp holder 20 with a square cross-sectional profile correspond one-to-one with the four edges of the cylinder shell 51 with a square cross-sectional profile, thereby making the 360° beam angle light output have a more uniform lighting effect.

[0067] like Fig.10 and Fig.12 As shown, the side wall of the columnar lamp holder 20 is provided with a plurality of buckle grooves 24. Fig. 9 As shown, the end cap 52 is provided with a plurality of hooks 521. In the LED lamp of the second embodiment, the plurality of hooks 521 extend into the hollow cavity 21 and are hooked in the plurality of buckle grooves 24 one by one. Fig. 9 As shown, the end cover 52 is provided with a plurality of positioning posts 522 arranged at intervals. When the end cover 52 is connected to the columnar lamp holder 20, the plurality of positioning posts 522 are first aligned one-to-one with the plurality of positioning holes on the second end of the columnar lamp holder 20 so that the end cover 52 is quickly positioned. At this time, the plurality of hooks 521 have also been one-to-one corresponding to the plurality of buckle grooves 24. Then, the end cover 52 is pushed so that the plurality of hooks 521 of the end cover 52 are one-to-one correspondingly hooked on the plurality of buckle grooves 24. The end cover 52 can be installed so that the assembly efficiency is high.

[0068] The LED lamp provided in the second embodiment is compared with the LED lamp provided in the first embodiment. Except for the above structure, the other structures are the same, so they are not described here in detail.

[0069] 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.
