[0001] The present invention belongs to the technical field of lighting devices, and in particular relates to an LED lamp. Background Art

[0002] LED lamps are widely used in various places due to their easy installation and maintenance, power saving, high brightness and small size.

[0042] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood. The directions such as "axial direction", "above", "below", etc. in the following text are all for the purpose of more clearly indicating the structural position relationship and are not limitations of the present invention. In the present invention, the "vertical", "horizontal" and "parallel" are defined as: including the situation of ±10% based on the standard definition. For example, vertical usually refers to an angle of 90 degrees relative to the reference line, but in the present invention, vertical refers to the situation within 80 to 100 degrees.

[0043] like Figures 1 to 8 As shown in Figures 1 and 14, the present invention provides an LED lamp in one embodiment, comprising: a housing 1, a light source unit 2, a power source unit 3, a heat sink 4, a lamp holder 5, and a rotating member 6. The heat sink 4 is connected to the housing 1 and is arranged at one end of the housing 1; the power source unit 3 is arranged inside the housing 1; the light source unit 2 is arranged on the heat sink 4 and is connected to the power source unit 3 by wire; the lamp holder 5 is connected to the housing 1 and is arranged at the end opposite to the light source unit 2; and the rotating structure 6 is arranged at the connecting portion between the housing 1 and the heat sink 4.

[0044] like Figure 5 , 6 As shown, the rotating structure 6 may include a first rotating member 61 and a second rotating member 62. The first rotating member 61 and the second rotating member 62 are arranged opposite to each other. The first rotating member 61 and the second rotating member 62 interact with each other to enable the housing of the LED lamp to rotate, thereby driving the heat sink 4 and the light source part 2 to rotate at the same time (the relationship between the two remains consistent) to control the light emission direction of the LED lamp.

[0045] When changing the light emitting direction of the LED lamp, it is only necessary to make the first rotating member 61 and the second rotating member 62 rotate relative to each other, and there is no need to plug or unplug the first rotating member 61 and the second rotating member 62, thereby avoiding damaging the electrical connection between the various parts of the LED lamp during plugging or unplugging.

[0046] like Figures 4 to 7As shown, the first rotating member 61 may further include a first rotating surface 611, and the second rotating member 62 may include a second rotating surface 621. The first rotating surface 611 and the second rotating surface 621 are arranged opposite to each other, and the first rotating surface 611 and the second rotating surface 621 are arranged in parallel or substantially parallel. The size of the first rotating surface 611 and the second rotating surface 621 may be the same or substantially the same. At the same time, in order to make the LED lamp present better integrity, at least 50% of the area of ​​the first rotating surface 611 and the second rotating surface 621 are in contact with each other, so that there will be no obvious gap between the first rotating surface 611 and the second rotating surface 621, which affects the product quality. In the height direction of the LED lamp (as a whole), the acute angle between the first rotating surface 611 and the side wall of the housing 1 is a, and the acute angle between the second rotating surface 621 and the side wall of the housing 1 is b, and the angle a is the same or substantially the same as the angle b. In order to change the light emitting direction of the LED lamp from vertical to horizontal, and to prevent the light emitting direction from changing too much or too little, the angle a is 15°≤a≤75°. When the angle is less than 15°, the light emitting direction changes too much; when the angle is greater than 75°, the light emitting direction changes too little. Preferably, 30°≤a≤60°; more preferably, angle a=45°. Because angle a is the same or approximately the same as angle b, that is, angle b, 15°≤b≤75°; preferably, angle b, 30°≤b≤60°; more preferably, angle b=45°. When angle a / angle b is 45°, the light emitting direction of the LED lamp can undergo a 90° conversion and change.

[0047] like Figure 5 , 6As shown, the first rotating member 61 may include a first rotating portion 612, and the second rotating member 62 may include a second rotating portion 622, and the first rotating portion 612 is connected to the second rotating portion 622, so that the rotating member 61 has a rotating effect. Specifically, in one embodiment, the second rotating portion 622 may be inserted into the first rotating portion 612, that is, the second rotating portion 622 is at least partially located in the first rotating portion 612. The second rotating portion 622 may rotate relatively in the first rotating portion 612. The second rotating portion 622 may be an extension of the second rotating member 62 toward the first rotating portion 612, and the first rotating portion 612 may be an opening. The outer surface of the second rotating portion 622 contacts one or more portions of the first rotating portion 612 to achieve connection and cooperation, so that the first rotating member 61 and the second rotating member 62 rotate relatively. In other embodiments, the first rotating portion 612 may be inserted into the second rotating portion 622 and rotate relatively therein. The first rotating portion 612 can be an extension of the first rotating member 62 toward the second rotating portion 622, and the second rotating portion 622 can be an opening. The outer surface of the first rotating portion 612 contacts one or more portions of the second rotating portion 622 to achieve connection and fit, so that the first rotating member 61 and the second rotating member 62 rotate relative to each other.

[0048] like Figure 5 , 6As shown in FIGS. 24 and 25, the first rotating member 61 may further include a first limiting member 613, and the second rotating member 62 may further include a second limiting member 623. The first limiting member 613 contacts and interacts with the second limiting member 623, and after the LED lamp is rotated to a predetermined position, the limiting member 613 is fixed. The first limiting member 613 may include a groove, and the second limiting member 623 may include a convex portion. The second limiting member 623 is at least partially disposed in the first limiting member 613, and the second limiting member 623 can move in the first limiting member 613. In this embodiment, the first limiting member 613 may include a stopper 6131 and a first groove 6132, and the second limiting member 623 may be a convex portion facing the first rotating member 61. After the first rotating member 61 and the second rotating member 62 rotate to the set position, the second limiting member 623 is inserted into the first groove 6132 of the first limiting member 613, so that the second limiting member 623 moves in the first groove 6132. When the second limiting member 623 rotates to the stopper 6131, the second rotating member 62 can be limited to rotate relative to the first rotating member 61 by the stopper effect of the stopper 6131 to prevent over-rotation. Further, the stopper 6131 may include a step 61311, so that the second rotating member 62 is not easy to slide out after entering the step 61311, thereby fixing the relative position of the first rotating member 61 and the second rotating member 62 after rotation. In one embodiment, the first limiting member 613 may be a stopper, and the second limiting member 623 may be a protrusion toward the first rotating member 61. After the first rotating member 61 and the second rotating member 62 rotate to the set position, the first limiting member 613 blocks the movement of the second limiting member 623, thereby limiting the rotation of the second rotating member 62 relative to the first rotating member 61 to prevent over-rotation. In other embodiments, the first limiting member 613 may be a groove, and the second limiting member 623 may be a protrusion facing the first rotating member 61. After the first rotating member 61 and the second rotating member 62 rotate to the set position, the second limiting member 623 is inserted into the first limiting member 613 to limit the movement of the second limiting member 623, thereby limiting the rotation of the second rotating member 62 relative to the first rotating member 61 to prevent over-rotation.

[0049] like Figures 3 to 6 As shown, the first rotating member 61 of the rotating member 6 can be arranged on the heat sink 4, and the second rotating member 62 of the rotating member 6 can be arranged on the housing 1. The heat sink 4 and the housing 1 are relatively rotated by the rotating member 6. Since the light source part 3 is located on the heat sink 4, when the heat sink 4 and the housing 1 are relatively rotated, the light source part 3 and the housing 1 are relatively rotated at the same time, so that the direction of the light source part 3 can be changed, and then the light emitting direction of the LED lamp is changed.

[0050] like Figure 4 ,8 As shown, the light source unit 2 includes a lamp board 21, and the lamp board 21 is in contact with the heat sink 4. The lamp board 21 may include a first light-emitting unit 211, and further, the first light-emitting unit 211 may include a lamp bead 2111. By lighting the lamp bead 2111, the LED lamp has a lighting effect. The lamp board 21 may also include a second light-emitting unit 212, and the second light-emitting unit 212 includes a lamp bead 2112 that can emit light of a different color temperature from the lamp bead 2111, that is, the first light-emitting unit 211 and the second light-emitting unit 212 emit light of different color temperatures, so that the LED lamp has the function of adjusting the color temperature.

[0051] like Figures 1 to 5 As shown in Figures 1 and 8, the light source unit 2 may further include a light source cover 22 which is arranged on the light emitting side of the lamp board 21. The light source cover 22 is connected and fixed to the radiator 4. Specifically, the light source cover 22 and the radiator 4 may be connected by means of snap connection, buckle connection, gluing, etc. The light source cover 22 may include an arc surface, and the light emitted from the lamp board 21 is refracted after passing through the arc surface of the light source cover 22, so that the light emitting range of the LED lamp can be enlarged through the effect of the arc surface. Materials that can diffuse light, such as diffusion powder, can also be added to the light source cover 22, so that the light emitted by the LED lamp can be softer. The light source cover 22 may include a side portion 221 that allows light to pass through, and through the light transmission effect of the side portion 221, the range of illumination of the light emitted from the lamp board 21 can be wider and the light emission can be softer.

[0052] The heat sink 4 may include a lamp board fixing portion 42 for fixing the lamp board 21. The lamp board 21 may be fixed to the lamp board fixing portion 42 of the heat sink by gluing, screw locking, riveting, or the like.

[0053] The heat sink 4 may be made of metal, such as aluminum, aluminum alloy, etc., to improve the heat dissipation effect. The heat sink 4 may include heat dissipation fins 41 for heat dissipation.

[0054] like Figures 9 to 13 As shown, the lamp head 5 of the LED lamp may include a shell fixing portion 52 for connecting and fixing with the shell 1. The shell fixing portion 52 and the corresponding connecting portion of the shell 1 can be connected and fixed by means of snap connection, buckle connection, screws, adhesive, etc. or a combination of the above connection methods.

[0055] The lamp holder 5 may further include a lamp holder rotating portion 51 , through which the lamp holder rotating portion 51 can be used to relatively rotate the lamp holder 5 and the housing 1 , thereby adjusting the light emitting direction of the LED lamp.

[0056] Specifically, the lamp holder rotating part 51 can be connected with the shell fixing part 52 so that the shell 1 and the shell 5 can rotate relative to each other. The lamp holder rotating part 51 and the shell fixing part 52 can be connected and fixed by means of snap connection, buckle connection, etc. The lamp holder rotating part 51 includes a first rotating unit 511, and the shell fixing part 52 includes a second rotating unit 521. The first rotating unit 511 and the second rotating unit 521 cooperate with each other so that the lamp holder 5 and the shell 1 can rotate relative to each other. In this embodiment, the first rotating unit 511 can be a barb portion, and the second rotating unit 521 can be a protrusion of the shell fixing part 52 protruding toward the first rotating unit 511. The first rotating unit 511 abuts against the second rotating unit 521, and when rotating, the second rotating unit 521 is connected with the first rotating unit 511, so that the second rotating unit 521 rotates on the side of the first rotating unit 511 away from the shell 1. In other embodiments, the second rotating unit 521 may be a barb, and the first rotating unit 511 may be a protrusion of the lamp holder rotating part 51 toward the second rotating unit 521. The first rotating unit 511 abuts against the second rotating unit 521, and when rotating, the second rotating unit 521 is connected with the first rotating unit 511, so that the second rotating unit 521 rotates on the side of the first rotating unit 511 away from the housing 1 (that is, regardless of the specific structure of the first rotating unit 511 and the second rotating unit 521, the role of the connection between the two is that the second rotating unit 521 rotates on the side of the first rotating unit 511 away from the housing 1, so that when the lamp holder rotating part rotates, the housing fixing part is always inside the lamp holder rotating part and will not be separated from the outside of the lamp holder rotating part). The first rotating unit 511 and the second rotating unit 521 can also adopt other matching methods to achieve relatively stable rotation of the housing 1 and the lamp holder 5, and prevent the lamp holder 5 from falling off.

[0057] The housing fixing portion 52 may include a lamp holder rotation limiting portion 522. Through the limiting effect of the lamp holder rotation limiting portion 522 of the lamp holder 5, when the lamp holder 5 rotates relative to the housing 1, it plays a limiting role to prevent the lamp holder 5 from over-rotating. Specifically, the lamp holder rotation limiting portion 522 may be located on the second rotating unit 521, so that the lamp holder rotation limiting portion 522 can be integrated with the second rotating unit 521, and the structure is simpler. The lamp holder rotation limiting portion 522 may also be located outside the second rotating unit 521, that is, the lamp holder rotation limiting portion 522 and the second rotating unit 521 are not integrally arranged, so as to effectively avoid the installation and rotation difficulties caused by the large interference and the risk of the lamp holder falling off due to the small interference. The lamp holder rotating portion 51 may include a limiting matching portion 512, and the limiting matching portion 512 cooperates with the lamp holder rotation limiting portion 522 to achieve the limiting effect.

[0058] More specifically, the lamp holder rotation limit portion 522 may be a protruding portion of the shell fixing portion 52 facing outward, and the limit matching portion 512 may be a stop portion arranged on the inner side of the lamp holder rotation portion. During rotation, the lamp holder rotation portion 51 rotates relative to the shell fixing portion 52, and the limit matching portion 512 rotates relative to the lamp holder rotation limit portion 522, so that the rotation stops when the limit matching portion 512 hits the lamp holder rotation limit portion 522, thereby achieving a limiting effect. In this embodiment, the shell fixing portion 52 is provided with two oppositely arranged first lamp holder rotation limiting portions 5221 and second lamp holder rotation limiting portions 5222 (the preferred angle difference between the two is 180°), and the lamp holder rotating portion 51 is provided with two oppositely arranged limiting matching portions 512 (the preferred angle difference between the two is 180°), so that when the rotation in one direction reaches the limit, the two limiting matching portions 512 respectively abut against the first lamp holder rotation limiting portion 5221 and the second lamp holder rotation limiting portion 5222, and the final limit cannot be over-rotated. In other embodiments, the lamp holder rotation limiting portion 522 and the limiting matching portion 512 can also adopt other matching methods to enable the shell 1 and the lamp holder 5 to achieve relatively stable rotation without over-rotation. In this embodiment, the two limiting matching portions 512 are long groove portions arranged on the lamp holder rotating portion 51.

[0059] like Fig.14 As shown, the lamp holder 5 may further include a second power supply board 53. The second power supply board 53 is disposed on the lamp holder rotating portion 51. Specifically, the second power supply board 53 may be fixed to the lamp holder rotating portion 51 by gluing, screw locking, riveting, etc. The second power supply board 53 is electrically connected to the power supply unit 3. The second power supply board 53 may be parallel or substantially parallel to the setting direction of the lamp board 21.

[0060] like Fig. 27 , 28 As shown in FIG. 29 , the second power board 53 can also be arranged perpendicular to the mounting surface of the lamp board 21 so that it can be installed by plugging in to improve the convenience of installation. Specifically, the lamp head rotating part 51 can include a fixing groove 513, and the second power board 53 can be inserted into the fixing groove 513.

[0061] like Figures 14 to 16 As shown in , 22, and 30, the housing 1 may include a cavity, and the power supply unit 3 may be accommodated in the cavity of the housing 1. The power supply unit may include a power board 31. The power board 31 is electrically connected to the light board 21 of the light source unit 2. Fig.30), the power board 31 can be electrically connected to the lamp board 21 of the light source unit 2 through the wire 311. The wire 311 can pass through the first rotating member 61 and the second rotating member 62 in sequence to reach the lamp board 21. The width D1 of the end of the power board 31 away from the light source can be smaller than the width D2 of the end of the power board 31 close to the light source, so that it can be accommodated in the housing 1 in conjunction with other components. In addition, in other embodiments of the present application, the power board 31 of the power supply unit 3 and the lamp board 21 of the light source unit 2 can also be electrically connected through other conductor connection methods, such as by providing a conductive metal sheet in the first rotating member 61 (not shown in the figure), and connecting the lamp board 21 and the power board 31 through the holes of the first rotating part 612 and the second rotating part 622, so that the two are electrically connected.

[0062] like Figures 14 to 16 As shown in FIG. 22 , the housing 1 may include a power board fixing portion 12. The power supply portion 3 is fixed to the housing 1 through the power board fixing portion 12. The power board fixing portion 12 may be a card slot structure, and the power board 3 is inserted into the card slot of the power board fixing portion.

[0063] like Figure 1 , 3 As shown in Figures 1 to 4, the housing 1 may include a dimming component 13. The color temperature of the light emitted by the light source unit 2 can be changed by the adjustment of the dimming component 13. The dimming component 13 may include an operating portion 131. The color temperature of the light emitted by the light source unit 2 can be adjusted by controlling the operating portion 131. The dimming component 13 may also include a groove 132, and the operating portion 131 may be disposed in the groove 132. The operating portion 131 may move in the groove 132, and the moving range of the operating portion 131 is limited by the size of the groove 132. In addition, since the operating portion 131 does not have too many protruding parts relative to the entire LED lamp, the housing 1 is more beautiful as a whole. In order to more conveniently operate the operating portion 131, the operating portion 131 may include a control component 1311. The control component 1311 may be a raised portion or a recessed portion, so that friction is increased during operation to facilitate operation.

[0064] like Fig.26 As shown, the operating part 131 may include an operating connection part 1312, and the power board 31 includes a controller 311. The operating connection part 1312 is connected to the controller 311, so that the user can adjust the controller 311 by turning the operating part 131, thereby realizing circuit control and adjusting the light color temperature of the LED lamp. Specifically, the controller 311 may include a switch part 3111. The operating connection part 1312 may be two clamping feet, and the two clamping feet are respectively arranged on both sides of the switch part 3111, and the switch part 3111 is fixed in the middle of the operating connection part 1312. The operating connection part 1312 can be made of a material with elastic deformation, such as plastic. Thereby, the operating connection part 1312 and the switch part 3111 are not easily misplaced or fall off through interference fit.

[0065] like Figures 16 to 18 As shown, the LED lamp may further include a stretching portion 7, which may be disposed between the housing 1 and the lamp holder 5. Through the stretching action of the stretching portion 7, the LED lamp may be stretched, thereby lengthening the entire length of the LED lamp. The stretching portion 7 may include a first stretching structure 71, which is located between the lamp holder 5 and the housing 1, and has a certain length in the length direction of the LED lamp. During the use of the LED lamp, when the stretching portion 7 of the LED lamp is stretched, the first stretching member 71 is stretched (extended) in a direction away from the light source (or opposite to the light emitting direction), thereby lengthening the LED lamp (second state). In this embodiment, when the stretching portion 7 is not stretched (first state), a portion of the first stretching member 71 is located inside the housing 1, and further, a portion of the first stretching member 71 may be located inside the lamp holder 5. When the stretching portion 7 is stretched, the first stretching member 71 is pulled out of the housing 1 and exposed outside the housing 1. In other embodiments, the first stretching member 71 may be partially located outside the housing 1. When the stretching portion 7 is stretched, the first stretching member 71 moves in a direction away from the light source (or opposite to the light emitting direction), and the housing 1 partially covered by the first stretching member 71 is exposed.

[0066] The first tensile member 71 may include a barrel 714 and a stopper 715. The stopper 715 is disposed at an end of the first tensile member 71 close to the light source, and the barrel 714 is disposed at an end of the first tensile member 71 far from the light source compared to the stopper 715. The outer circumference of the stopper 715 is greater than the outer circumference of the barrel 714, and the stopper 715 can effectively prevent the first tensile member 71 from being over-stretched from the housing 1 (completely separated from the housing 1) and falling off.

[0067] like Figures 14 to 22As shown, the stretching portion 7 may further include a second stretching member 72, which is located between the housing 1 and the lamp holder 5. The second stretching member 72 is fixedly connected to the housing 1. Further, the second stretching member 72 may be sleeved on the outside of the first stretching member 71. The first stretching member 71 may include a receiving groove 712, and the second stretching member 72 may include a sliding arm 721, which may be at least partially received in the receiving groove 712 and can move in the receiving groove 712, so that the stretching portion 7 of the LED lamp plays a stretching role. The second stretching member 72 may include a second housing connection portion 722, which is connected and fixed to the housing 1. Specifically, the second housing connection portion 722 may include a first fixing member 7221, and the housing 1 may include a second fixing member 11, and the first fixing member 7221 is connected and matched with the second fixing member 11. The first fixing member 7221 may be one or more protrusions, and the second fixing member 11 may be an opening corresponding to the first fixing member 7221. The first fixing member 7221 is inserted into the second fixing member 11, so that the second tensile member 72 is connected and fixed to the housing 1. The second housing connection portion 722 may further include a third fixing member 7222, which is sleeved on the end of the housing 1 and abuts against the outer edge of the end of the housing 1, so as to further connect and fix the second tensile member 72 to the housing 1. The inner circumference of the third fixing member 7222 is ≥ the outer circumference of the barrel 714 of the first tensile member 71, so that the barrel 714 of the first tensile member 71 can move relatively in the second tensile member 72. The inner circumference of the third fixing member 7222 is ≤ the outer circumference of the stopper 715 of the first tensile member 71, so that the first tensile member 71 can be prevented from being excessively pulled out.

[0068] like Figures 14 to 20As shown, the first stretching member 71 may include a third limiting member 713, and the sliding arm 721 of the second stretching member 72 may include a second limiting member 7211. The third limiting member 713 cooperates with the second limiting member 7211 to limit the stretching of the stretching portion 7 to prevent improper over-stretching. Specifically, the third limiting member 713 may be an open circular hole and located at the end of the receiving groove 712 of the first stretching member. The second limiting member 7211 may be a convex column facing the axial direction of the LED lamp. The second limiting member 7211 may be located on the sliding arm 721 of the second stretching member 72; further, the second limiting member 7211 may be located on the end of the sliding arm 721 of the second stretching member 72 close to the light source. When the first stretching member 71 is pushed to the housing 1, when the maximum entry value is reached, the second limiting member 7211 is clamped into the third limiting member 713, so that the first stretching structure 71 will not be pushed excessively into the housing 1. Two opening grooves can be respectively set on both sides of the third limiting member 713, which increases the elastic deformation of the third limiting member 713, so that when the first tensile member 71 is pulled, the second limiting member 7211 can be pulled out under the action of appropriate force, thereby playing a tensile role for the LED lamp.

[0069] The end of the sliding arm 721 of the second tensile member 72 close to the light source may contact the power board 81, thereby playing a role of fixing and limiting the power board 81. The end of the sliding arm 721 of the second tensile member 72 close to the light source may not contact the power board 81, but only close to the power board 81, thereby preventing the power board 81 from excessive displacement and playing a role of limiting the power board 81 to a certain extent.

[0070] like Figures 14 to 23As shown, the first tensile member 71 may include a first shell connecting portion 711 on the side facing the lamp holder 5, and the first shell connecting portion 711 cooperates with the lamp holder rotating portion 51 of the lamp holder 5 to enable the shell 1 and the shell 5 to rotate relative to each other. The lamp holder rotating portion 51 and the first shell connecting portion 711 may be connected and fixed by means of snap connection, buckle connection, etc. The lamp holder rotating portion 51 includes a first rotating unit 511, and the first shell connecting portion 711 includes a second rotating unit 7111. The first rotating unit 511 and the second rotating unit 7111 cooperate with each other to enable the lamp holder 5 and the shell 1 to rotate relative to each other. In this embodiment, the first rotating unit 511 may be a barb portion, and the second rotating unit 7111 may be a protrusion of the first shell connecting portion 711 protruding in a direction away from the axis of the LED lamp. The first rotating unit 511 abuts against the second rotating unit 7111. When rotating, the second rotating unit 7111 is connected by the first rotating unit 511, so that the second rotating unit 7111 rotates on the side of the first rotating unit 511 away from the housing 1. In other embodiments, the second rotating unit 7111 may be a barb, and the first rotating unit 511 may be a protrusion of the lamp holder rotating part 51 that protrudes in a direction away from the axial center of the LED lamp. The first rotating unit 511 abuts against the second rotating unit 7111. When rotating, the second rotating unit 7111 is connected by the first rotating unit 511, so that the second rotating unit 7111 rotates on the side of the first rotating unit 511 away from the housing 1 (that is, regardless of the specific structures of the first rotating unit 511 and the second rotating unit 7111, the function of the connection between the two is that the second rotating unit 7111 rotates on the side of the first rotating unit 511 away from the housing 1, so that when the lamp holder rotating part rotates, the housing fixing part is always inside the lamp holder rotating part and will not be separated from the outside of the lamp holder rotating part). The first rotating unit 511 and the second rotating unit 7111 may also be matched in other ways to enable the housing 1 and the lamp holder 5 to achieve relatively stable rotation without causing the lamp holder 5 to fall off.

[0071] The first housing connection portion 711 may include a lamp holder rotation limiting portion 7112. Through the limiting effect of the lamp holder rotation limiting portion 7112 of the lamp holder 5, when the lamp holder 5 rotates relative to the housing 1, it plays a limiting role to prevent the lamp holder 5 from over-rotating. Specifically, the lamp holder rotation limiting portion 7112 may be located on the second rotating unit 7111, so that the lamp holder rotation limiting portion 7112 can be integrated with the second rotating unit 7111, and the structure is simpler. The lamp holder rotation limiting portion 7112 may also be located outside the second rotating unit 7111, that is, the lamp holder rotation limiting portion 7112 and the second rotating unit 7111 are not integrally arranged, thereby effectively avoiding the difficulty of installation and rotation caused by a large interference and the risk of the lamp holder falling off due to a small interference. The lamp holder rotating portion 51 may include a limiting matching portion 512, and the limiting matching portion 512 cooperates with the lamp holder rotation limiting portion 712 to achieve a limiting effect.

[0072] More specifically, the lamp holder rotation limit portion 7112 may be a protrusion of the first tensile member 71 that protrudes in a direction away from the axial center of the LED lamp, and the limit fitting portion 512 may be a stop portion arranged on the inner side of the lamp holder rotation portion. During rotation, the lamp holder rotation portion 51 rotates relative to the first shell connection portion 711, and the limit fitting portion 512 rotates relative to the lamp holder rotation limit portion 7112, so that the rotation stops when the limit fitting portion 512 hits the lamp holder rotation limit portion 7112, thereby achieving a limiting effect. In this embodiment, the first shell connecting portion 711 is provided with two relatively arranged first lamp holder rotation limiting portions 7113 and second lamp holder rotation limiting portions 7114 (the preferred angle difference between the two is 180°), and the lamp holder rotation portion 51 is provided with two relatively arranged first limiting matching portions 5121 and second limiting matching portions 5122 (the preferred angle difference between the two is 180°), the first limiting matching portion 5121 is located on one side between the first lamp holder rotation limiting portion 7113 and the second lamp holder rotation limiting portion 7114, and the second limiting matching portion 5122 is located on the first lamp holder rotation limiting portion 7113 and the second lamp holder rotation limiting portion 7114. The first position-limiting matching part 5121 abuts against the first lamp holder rotation limit part 7113 and the second position-limiting matching part 5122 abuts against the second lamp holder rotation limit part 7114 when the rotation reaches the limit in one direction, and the final limit cannot be over-rotated; or when the rotation reaches the limit in the opposite direction, the first position-limiting matching part 5121 abuts against the second lamp holder rotation limit part 7114 and the second position-limiting matching part 5122 abuts against the first lamp holder rotation limit part 7113, and the final limit cannot be over-rotated. In other embodiments, the lamp holder rotation limit part 7112 and the position-limiting matching part 512 may also adopt other matching methods to enable the housing 1 and the lamp holder 5 to achieve relatively stable rotation without over-rotation.

[0074] For example, the shell may include a cavity, and the power supply unit may be accommodated in the cavity of the shell.

[0075] For example, the second rotating portion may be an extension portion extending toward the first rotating portion, and the first rotating portion may be an opening.
