In the semiconductor, light photons are emitted by the recombination of carriers, directly emitting red, yellow, blue and green light. On this basis, by adding fluorescent powder, any color light can be emitted. The lighting appliance made of LED as light source is LED lamp. In the use process of LED lighting lamp, the LED lighting lamp is usually fixed and installed directly on the corresponding working position, and then the on-off control operation of the LED lighting lamp is completed through the control switch.

[0037] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , the base 1 upside is provided with rotating assembly for controlling the rotation of the lamp cylinder 4, rotating assembly includes sliding through the first threaded rod 14 of the clamping plate 3, the first threaded rod 14 is located in the clamping plate 3 threaded sleeve with threaded ring 6, threaded ring 6 and clamping plate 3 rotation connection, the side wall of the fixed rod 5 is fixedly connected with the second connecting rod 13, the second connecting rod 13 rotationally penetrates the clamping plate 3, the second connecting rod 13 and the outer side of the threaded ring 6 are fixedly connected with the second gear 7, a plurality of heat dissipation rods 10 are rotationally installed in the clamping plate 3, a plurality of third connecting rods 8 are also rotationally connected in the clamping plate 3, the plurality of heat dissipation rods 10 and the third connecting rods 8 are staggered, the outer side of the plurality of heat dissipation rods 10 is fixedly connected with the fourth gear 11, the outer side of the plurality of third connecting rods 8 is fixedly connected with the third gear 9, the third gear 9 and the fourth gear 11 are engaged, and the fourth gear 11 and the second gear 7 located at the both ends of the clamping plate 3 are engaged, the heat dissipation rod 10 is fixedly connected with the heat dissipation plate 12 on the side away from the clamping plate 3, the base 1 upside is provided with control assembly for controlling the movement of the first threaded rod 14, the control assembly includes motor 20 fixedly installed on the upper side of the base 1, the output end of the motor 20 is fixedly installed with the rotating shaft 21, the outer side of the rotating shaft 21 is fixedly installed with the first gear 22, the upper side of the base 1 is slidingly connected with two sliding plates 16, the two sliding plates 16 are respectively fixedly connected with the first threaded rod 14, the side wall of the two first threaded rods 14 is fixedly connected with the first connecting rod 24, the outer side of the first connecting rod 24 is fixedly connected with the rack 23, the rack 23 and the first gear 22 are engaged;

[0038] First, when it is necessary to control the lamp tube 4 to rotate, the motor 20 is started, and the motor 20 drives the first gear 22 to rotate through the rotating shaft 21, and the first gear 22 drives the rack 23 to move, and the rack 23 drives the first threaded rod 14 to move through the first connecting rod 24. Since the first threaded rod 14 and the clamping plate 3 are in sliding connection, and the first threaded rod 14 and the threaded ring 6 are in threaded connection, the moving first threaded rod 14 will drive the threaded ring 6 to rotate, and the threaded ring 6 will drive the second gear 7 to rotate, and then drive the gear fixed on the second connecting rod 13 under the transmission action of the third gear 9 and the fourth gear 11. The second gear 7 on the outside rotates, and the second gear 7 rotates through the second connecting rod 13 and the fixed rod 5.

In this process, under the action of the rotating fourth gear 11, the heat dissipation rod 10 will rotate, and the heat dissipation rod 10 drives the heat dissipation plate 12 to rotate, thereby causing the heat dissipation plate 12 to generate cooling air that can be blown toward the lamp tube 4, thereby reducing the temperature of the lamp tube 15 and the lamp tube 4, so that the lamp tube 15 and the lamp tube 4 are always in good working condition, thereby improving the service life of the lamp tube 15.

[0039] like Figure 8 、 Figure 9 、 Figure 10 , a cleaning assembly is installed on the upper side of the base 1, and the cleaning assembly includes two support rods 25 fixedly installed on the upper side of the base 1, the outer sides of the two support rods 25 are slidably connected with collars 27, the side walls of the collars 27 are fixedly connected with first connecting plates 28, the two first connecting plates 28 are commonly fixedly connected with a first connecting ring 29, a sleeve 30 is rotatably connected in the first connecting ring 29, a telescopic cylinder 32 is fixedly connected between the sleeve 30 and the rotating shaft 21, a first spring 33 is also fixedly connected between the sleeve 30 and the rotating shaft 21, the outer side of the collar 27 is also fixedly connected to the fourth connecting rod 26, the outer side of the fourth connecting rod 26 is fixedly connected to the round rod 19, the upper side of the sleeve 30 is fixedly connected to the square rod 31, the outer side of the square rod 31 is slidably connected to the rotating plate 18, and the outer side of the rotating plate 18 is rotatably connected The third connecting ring 17, the outer side of the third connecting ring 17 is symmetrically fixedly connected to two second connecting plates 35, the two second connecting plates 35 slide through the support rod 25, and a second spring 37 is fixedly connected between the second connecting plate 35 and the support rod 25. A plurality of cleaning plates 34 are fixedly connected to the upper side of the rotating plate 18, and the plurality of cleaning plates 34 are rotationally symmetrical. The two support rods 25 are rotatably connected to the second threaded rod 36, and the second threaded rod 36 threadedly penetrates the second connecting plate 35. The second threaded rod 36 is located in the second connecting plate 35 and is slidably sleeved with a fifth gear 39. The fifth gear 39 is rotatably connected to the second connecting plate 35. A gear ring 40 is fixedly connected to the outer side of the rotating plate 18, and the gear ring 40 is meshed with the fifth gear 39. The square rod 31 and the inner wall of the rotating plate 18 are both arranged as regular polygons;

[0040] First, the outer side of the cleaning plate 34 is fixedly provided with a cleaning brush, secondly, under the action of the telescopic cylinder 32, the sleeve 30 and the rotating shaft 21 are in the upper and lower sliding connection state, after the motor 20 is started, without the action of external force, one end of the square rod 31 is located in the rotating plate 18, in the rotating process of the rotating shaft 21, the rotating shaft 21 drives the sleeve 30 and the square rod 31 to rotate through the telescopic cylinder 32, the square rod 31 drives the rotating plate 18 and the cleaning plate 34 to rotate, in this process, the cleaning plate 34 also rotates to generate cooling wind, thereby reducing the temperature of the outer side of the lamp cylinder 4, thereby further enabling the lamp tube 15 to be in a good working state, when the lamp tube 15 performs the lighting work for a long time, a certain amount of dust will accumulate on the outer side of the glass protective cover installed in the lamp cylinder 4, thereby causing the lighting brightness of the lamp tube 15 emitted from the lamp cylinder 4 to be low, at this time, the motor 20 can be started again to drive the lamp cylinder 4 as a whole to rotate until the lamp cylinder 4 and the cleaning plate 34 are opposite, that is, the glass protective cover in the lamp cylinder 4 is located on the upper side of the cleaning plate 34, in this process, the lamp cylinder 4 and the circular rod 19 abut, which causes the circular rod 19 to move downward relative to the base 1, the circular rod 19 drives the sleeve 27 to move downward through the fourth connecting rod 26, the sleeve 27 drives the first connecting ring 29 to move downward through the first connecting plate 28, the first connecting ring 29 drives the sleeve 30 to move downward, the sleeve 30 compresses the first spring 33, at the same time, the sleeve 30 drives the square rod 31 to move downward, the square rod 31 moves out of the rotating plate 18, at this time, the rotating plate 18 loses the rotating power and stops rotating, then in the continuous rotating process of the lamp cylinder 4, the lamp cylinder 4 and the cleaning plate 34 on the outer side of the rotating plate 18 abut, which causes the cleaning plate 34 to move downward, the cleaning plate 34 and the rotating plate 18 drive the third connecting ring 17 and the second connecting plate 35 to move downward, since the second threaded rod 36 is screwed through the second connecting plate 35, in the downward moving process of the second connecting plate 35, the second threaded rod 36 drives the fifth gear 39 to rotate, the fifth gear 39 drives the rotating plate 18 to rotate through the gear ring 40, the rotating plate 18 drives the cleaning plate 34 to rotate, when the glass protective cover in the lamp cylinder 4 is located on the upper side of the cleaning plate 34, there is a certain gap between the end of the lamp cylinder 4 and the glass protective cover, when the glass protective cover moves to the upper side of the cleaning plate 34, the cleaning plate 34 loses the restriction of the lamp cylinder 4, thereby causing the cleaning plate 34 to move upward, in the upward moving process of the cleaning plate 34, since the second threaded rod 36 is screwed through the second connecting plate 35, in the upward moving process of the second connecting plate 35, the second threaded rod 36 drives the fifth gear 39 to rotate, the fifth gear 39 drives the rotating plate 18 to rotate through the gear ring 40, the rotating plate 18 drives the cleaning plate 34 to rotate, the brush on the outer side of the cleaning plate 34 abuts against the glass protective cover, and the cleaning plate 34 is also in the rotating state, thereby forming the cleaning effect on the glass protective cover,This can ensure that the brightness of the light emitted by the lamp tube 15 from the lamp tube 4 is always in good working condition;

[0041] During the above working process, the second threaded rod 36 and the second connecting plate 35 will not be in a self-locking state, that is, the thread friction angle is smaller than the thread lead angle.

[0042] like Figure 11 A third threaded rod 42 is fixedly connected to the lower side of the lamp tube 15. The third threaded rod 42 is threadedly inserted into the lamp tube 4. A one-way bearing 41 is fixedly connected to the lower side of the third threaded rod 42. A second connecting ring 44 is slidably connected to the outer side of the one-way bearing 41. A plurality of fifth connecting rods 38 are fixedly connected to the lower side of the second connecting ring 44. A bottom plate 43 is fixedly connected to the lower side of the one-way bearing 41.

[0043] First, the second connecting plate 35 and the third connecting ring 17 are both hollow in shape. Secondly, a connected cavity is opened between the second connecting plate 35 and the third connecting ring 17. The upper side wall and the lower side wall of the second connecting plate 35 are both provided with through holes connected to the cavity. Among them, the inner wall of the upper through hole is engraved with a thread matching the second threaded rod 36, and the inner wall of the lower through hole does not contact the second threaded rod 36. When the lamp tube 15 and the lamp barrel 4 are working, when it is necessary to adjust the lighting effect, that is, when it is necessary to perform focusing adjustment, the motor 20 is started to rotate the lamp barrel 4 as a whole again after the angle is adjusted, so that the lamp barrel 4 returns to the initial position, so that the device as a whole is in Figure 1 The connection phenomenon, in Figure 12 In the process, although the device as a whole is changed from the Z state back to the X state, it is different from the cleaning of the glass protective cover. In this process, when the lamp tube 4 moves to this position, the lamp tube 4 will not abut against the round rod 19, and the fifth connecting rod 38 will also not abut against the round rod 19, thereby causing the rotating plate 18 to rotate continuously. When the fifth connecting rod 38 abuts against the cleaning plate 34, under the action of the cleaning plate 34, the fifth connecting rod 38 will rotate around the second connecting ring 44 as the center, and the second connecting ring 44 drives the one-way bearing 41 The one-way bearing 41 drives the third threaded rod 42 to rotate, thereby changing the position of the lamp tube 15 in the lamp tube 4. The focusing effect of the lamp tube 15 is due to the reflective effect of the reflector on the inner wall of the lamp tube 4. The position of the lamp tube 15 in the lamp tube 4 changes, that is, the position of the lamp tube 15 relative to the reflector changes, changing the focusing effect of the lamp tube 15 and reducing the phenomenon of dimming of the brightness emitted by the lamp tube 15 from the lamp tube 4. This is a function of the LED lighting itself, so it will not be redundantly described.

[0044] It should be emphasized here that in this solution, the adjustment of the LED light angle, cleaning of the glass protective cover and focusing adjustment are all done by rotating the lamp tube 4. When cleaning the glass protective cover, the lamp tube 4 in this solution is rotated from Figure 1The state rotates to 180 degrees, and the upper end of the lamp cylinder 4 is squeezed during the process, and the cleaning plate 34 is rotated to the upper side during the process, so that the round rod 19 is not touched, and the light adjusting is performed by restoring the lamp cylinder 4 to the initial position, that is, the state shown in the scheme Figure 1 The upper end of the lamp cylinder 4 is not rotated to the lower side during the process, so that the cleaning glass protection cover and the light adjusting are irrelevant.

[0045] A method for using the LED lighting lamp with adjustable illumination angle, comprising the following steps:

[0046] S1, the base 1 is fixedly installed on the working position, and the lamp tube 15 and the corresponding control switch are electrically connected, the lamp tube 15 is turned on and the brightness of the lamp tube 15 is adjusted through the control switch, and then the corresponding lighting operation is started;

[0047] S2, during the lighting process, the motor 20 is started, and the light angle is adjusted;

[0048] S3, the glass protection cover in the lamp cylinder 4 is cleaned by relatively arranging the glass protection cover and the base 1;

[0049] S4, the bottom of the lamp cylinder 4 and the base 1 are relatively arranged, the position of the lamp tube 15 in the lamp cylinder 4 is adjusted, and then the light adjusting effect is adjusted.

[0050] In the present application, the base 1 is installed on the corresponding working position by the bolt 2 during the use of the device as a whole, and the lamp tube 15 and the corresponding control switch are electrically connected, the lamp tube 15 is turned on and the brightness of the lamp tube 15 is adjusted through the control switch, and then the corresponding lighting operation is started, which are all prior art and will not be described in detail.

[0051] When it is necessary to control the rotation of the lamp barrel 4, the motor 20 is started, the motor 20 drives the first gear 22 to rotate through the rotating shaft 21, the first gear 22 drives the rack 23 to move, the rack 23 drives the first threaded rod 14 to move through the first connecting rod 24, since the first threaded rod 14 and the clamping plate 3 are in sliding connection, and the first threaded rod 14 and the threaded ring 6 are in threaded connection, therefore the moving first threaded rod 14 will drive the threaded ring 6 to rotate, the threaded ring 6 drives the second gear 7 to rotate, then under the transmission of the third gear 9 and the fourth gear 11, the second gear 7 fixedly installed outside the second connecting rod 13 is driven to rotate, the second gear 7 rotates through the second connecting rod 13 and the fixed rod 5, the fixed rod 5 drives the lamp barrel 4 to rotate with the fixed rod 5 as the center, thereby completing the adjustment operation of the illumination angle of the lamp 15, and in this process, under the action of the rotating fourth gear 11, the heat dissipation rod 10 will be caused to rotate, the heat dissipation rod 10 drives the heat dissipation plate 12 to rotate, thereby causing the heat dissipation plate 12 to generate cooling wind that can blow to the lamp barrel 4, thereby reducing the temperature of the lamp 15 and the lamp barrel 4, thereby keeping the lamp 15 and the lamp barrel 4 in a good working state, thereby improving the service life of the lamp 15;

[0052] After the motor 20 is started, one end of the square rod 31 is located in the rotating plate 18 without external force, and in the process of rotating the rotating shaft 21, the rotating shaft 21 drives the sleeve 30 and the square rod 31 to rotate through the telescopic cylinder 32, the square rod 31 drives the rotating plate 18 and the cleaning plate 34 to rotate, and in this process, the cleaning plate 34 also rotates to generate cooling air, thereby reducing the temperature outside the lamp cylinder 4, and further enabling the lamp tube 15 to be in a good working state. When the lamp tube 15 is in a long-time lighting work, a certain amount of dust will accumulate on the outside of the glass protective cover installed in the lamp cylinder 4, thereby causing the illumination brightness of the lamp tube 15 emitted from the lamp cylinder 4 to be low. At this time, the motor 20 can be started again to drive the lamp cylinder 4 as a whole to rotate until the lamp cylinder 4 and the cleaning plate 34 are opposite, that is, the glass protective cover in the lamp cylinder 4 is located directly above the cleaning plate 34. In this process, the lamp cylinder 4 and the circular rod 19 are in contact, which causes the circular rod 19 to move downward relative to the base 1. The circular rod 19 drives the sleeve ring 27 to move downward through the fourth connecting rod 26, the sleeve ring 27 drives the first connecting ring 29 to move downward through the first connecting plate 28, the first connecting ring 29 drives the sleeve 30 to move downward, the sleeve 30 compresses the first spring 33, and at the same time, the sleeve 30 drives the square rod 31 to move downward, and the square rod 31 moves out of the rotating plate 18. At this time, the rotating plate 18 loses the driving force for rotation and stops rotating. Then, in the process of continuing to rotate the lamp cylinder 4, the lamp cylinder 4 and the cleaning plate 34 outside the rotating plate 18 abut to cause the cleaning plate 34 to move downward, and the cleaning plate 34 and the rotating plate 18 drive the third connecting ring 17 and the second connecting plate 35 to move downward. Since the second threaded rod 36 is screwed through the second connecting plate 35, in the process of moving the second connecting plate 35 downward, the second threaded rod 36 drives the fifth gear 39 to rotate, the fifth gear 39 drives the rotating plate 18 to rotate through the gear ring 40, and the rotating plate 18 drives the cleaning plate 34 to rotate. When the glass protective cover in the lamp cylinder 4 is located directly above the cleaning plate 34, there is a certain gap between the end of the lamp cylinder 4 and the glass protective cover. When the glass protective cover moves to the position directly above the cleaning plate 34, the cleaning plate 34 loses the restriction of the lamp cylinder 4, thereby causing the cleaning plate 34 to move upward. In the process of moving the cleaning plate 34 upward, since the second threaded rod 36 is screwed through the second connecting plate 35, in the process of moving the second connecting plate 35 upward, the second threaded rod 36 drives the fifth gear 39 to rotate, the fifth gear 39 drives the rotating plate 18 to rotate through the gear ring 40, and the rotating plate 18 drives the cleaning plate 34 to rotate. The brushes outside the cleaning plate 34 abut to the glass protective cover, and the cleaning plate 34 is also in a rotating state, thereby forming a cleaning effect on the glass protective cover, and thereby enabling the illumination brightness of the lamp tube 15 emitted from the lamp cylinder 4 to be in a good working state at all times;

[0053] When the light tube 15 and the lamp cylinder 4 are working, when the light effect needs to be adjusted, i.e. the spotlight needs to be adjusted, the motor 20 is started, the lamp cylinder 4 as a whole is rotated after the angle is adjusted, the lamp cylinder 4 is returned to the initial position, i.e. the device as a whole is in the X state Figure 1 The connecting phenomenon is in Figure 12 , even if the device as a whole changes from the Z state to the X state, and the glass protective cover is cleaned, in this process, when the lamp cylinder 4 moves to this position, the lamp cylinder 4 will not abut against the round rod 19, and the fifth connecting rod 38 will also not abut against the round rod 19, further causing the rotating plate 18 to keep rotating, when the fifth connecting rod 38 abuts against the cleaning plate 34, under the action of the cleaning plate 34, the fifth connecting rod 38 will rotate around the second connecting ring 44, the second connecting ring 44 drives the one-way bearing 41 to rotate, the one-way bearing 41 drives the third threaded rod 42 to rotate, further causing the position of the light tube 15 in the lamp cylinder 4 to change, the spotlight effect of the light tube 15 is because of the reflection effect of the reflecting plate in the inner wall of the lamp cylinder 4, the position of the light tube 15 in the lamp cylinder 4 changes, i.e. the position of the light tube 15 relative to the reflecting plate changes, the spotlight effect of the light tube 15 is changed, the phenomenon of the light tube 15 emitting light with reduced brightness from the lamp cylinder 4 is reduced, this is a function of the LED lighting lamp itself, thus it will not be described in detail.
