Description

Technical Field

[0001] The present invention relates to the technical field of LED lighting lamps, and in particular to an LED lighting lamp with adjustable lighting angle and a use method thereof. Background Art

[0002] LED lighting is light-emitting diode lighting, which is a semiconductor solid light-emitting device. It uses solid semiconductor chips as light-emitting materials. In the semiconductor, excess energy is released through the recombination of carriers, causing photon emission, directly emitting red, yellow, blue, and green light. On this basis, by using the principle of three primary colors and adding fluorescent powder, it can emit light of any color. The lighting fixture made using LED as the light source is the LED lamp. In the use of LED lighting, the LED lighting is often directly fixed and installed in the corresponding working position, and then the switch control operation of the LED lighting can be completed through the control switch. The overall structure is simple and the cost is low. In the actual working process, sometimes, the LED lighting lamp is driven to rotate by the rotating structure. At the same time, the corresponding lighting operation can be completed in conjunction with the control switch, which can form very beautiful lights and good stage effects. However, the above-mentioned rotating structure is simple in structure and can only complete the rotating operation. When the control switch is used to turn on the LED lighting lamp or adjust the lighting intensity of the LED lighting lamp, the temperature of the LED lighting lamp will rise rapidly, which is likely to cause damage to the internal components of the LED lighting lamp. At the same time, during the long-term use of the LED lighting lamp, a certain amount of dust will accumulate on the glass protective cover on the surface of the LED lighting lamp. If the dust cannot be cleaned in time, the lighting brightness of the LED lighting lamp will be greatly reduced. In the process of using the LED lighting lamp, it will gradually dim due to various reasons such as light decay, driver damage, and light bead burning. Sometimes it is necessary to manually disassemble the LED lighting, adjust the position of the lamp tube in the LED lighting, improve the focusing effect, and then eliminate the dimming phenomenon of the LED lighting, which is time-consuming, labor-intensive, and very troublesome.

The above are all prior arts and no redundant description is given; like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A rotating assembly for controlling the rotation of the lamp tube 4 is installed on the upper side of the base 1, and the rotating assembly includes a first threaded rod 14 that slides through the clamping plate 3, and the first threaded rod 14 is located in the clamping plate 3 and is threadedly sleeved with a threaded ring 6, and the threaded ring 6 is rotatably connected to the clamping plate 3. The side wall of the fixed rod 5 is fixedly connected with a second connecting rod 13, and the second connecting rod 13 rotatably passes through the clamping plate 3. The outer sides of the second connecting rod 13 and the threaded ring 6 are both fixedly connected with a second gear 7, and a plurality of heat dissipation rods 10 are rotatably installed in the clamping plate 3. A plurality of third connecting rods 8 are also rotatably connected in the clamping plate 3. The plurality of heat dissipation rods 10 and the third connecting rods 8 are staggered, and the outer sides of the plurality of heat dissipation rods 10 are all fixedly connected with a fourth gear 11, and the outer sides of the plurality of third connecting rods 8 are all fixedly connected with a third gear 9, and the third The gear 9 is meshed with the fourth gear 11, and the fourth gear 11 located at the two ends of the clamp plate 3 is meshed with the second gear 7. The heat dissipation rod 10 is fixedly connected to a heat dissipation plate 12 on one side away from the clamp plate 3. A control component for controlling the movement of the first threaded rod 14 is installed on the upper side of the base 1. The control component includes a motor 20 fixedly installed on the upper side of the base 1. A rotating shaft 21 is fixedly installed on the output end of the motor 20. A first gear 22 is fixedly installed on the outer side of the rotating shaft 21. Two slide plates 16 are slidably connected to the upper side of the base 1.

A rack 23 is fixedly connected to the outer side of the first connecting rod 24. The rack 23 is meshed with the first gear 22.

Since the first threaded rod 14 and the clamping plate 3 are slidably connected, and the first threaded rod 14 and the threaded ring 6 are threadedly connected, 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 fixedly installed 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, and the fixed rod 5 drives the lamp tube 4 to rotate around the fixed rod 5, thereby completing the adjustment operation of the lighting angle of the lamp tube 15, and in this process, under the action of the rotating fourth gear 11, the heat dissipation rod 10 will be caused to rotate, and the heat dissipation rod 10 drives the heat dissipation plate 12 to rotate, so that the heat dissipation plate 12 generates cooling wind that can be blown to 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 increasing the service life of the lamp tube 15.

[0016] like Figure 8 , Fig. 9 , Fig.10A 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, and the outer sides of the two support rods 25 are slidably connected with collars 27, and the side walls of the collars 27 are fixedly connected with a first connecting plate 28, and the two first connecting plates 28 are commonly fixedly connected with a first connecting ring 29, and a sleeve 30 is rotatably connected in the first connecting ring 29, and a telescopic cylinder 32 is fixedly connected between the sleeve 30 and the rotating shaft 21, and a first spring 33 is also fixedly connected between the sleeve 30 and the rotating shaft 21, and a fourth connecting rod 26 is also fixedly connected to the outer side of the collar 27, and a round rod 19 is fixedly connected to the outer side of the fourth connecting rod 26, and a square rod 31 is fixedly connected to the upper side of the sleeve 30, and 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 to The third connecting ring 17, the outer side of the third connecting ring 17 is symmetrically fixedly connected with two second connecting plates 35, the two second connecting plates 35 slide through the support rod 25, 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, the plurality of cleaning plates 34 are rotationally symmetrical, the two support rods 25 are both rotatably connected with a second threaded rod 36, the second threaded rod 36 is threadedly penetrated by 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 with the second connecting plate 35, a gear ring 40 is fixedly connected to the outer side of the rotating plate 18, 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 with regular polygons; First, a cleaning brush is fixedly installed on the outer side of the cleaning plate 34. Secondly, under the action of the telescopic cylinder 32, the sleeve 30 and the rotating shaft 21 are in an up and down 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. During the rotation 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, and the square rod 31 drives the rotating plate 18 and the cleaning plate 34 to rotate. During this process, the rotation of the cleaning plate 34 can also generate cooling wind, thereby reducing the temperature of the outer side of the lamp tube 4, thereby further putting the lamp tube 15 in a good working state. When the lamp tube 15 performs lighting work for a long time, the A certain amount of dust will accumulate on the outside of the glass protective cover, which will cause the brightness of the lighting emitted by the lamp tube 15 from the lamp barrel 4 to become lower. At this time, the motor 20 can be started again to drive the lamp barrel 4 to rotate as a whole until the lamp barrel 4 and the cleaning plate 34 are opposite to each other, that is, the glass protective cover in the lamp barrel 4 is located on the upper side of the cleaning plate 34. During this process, the lamp barrel 4 and the round rod 19 are against each other, which will cause the round rod 19 to move downward relative to the base 1. The round rod 19 drives the ring 27 to move downward through the fourth connecting rod 26. The 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. At the same time, the sleeve 30 drives the square rod 31 to move downward. The square rod 31 is moved out of the rotating plate 18, at which time the rotating plate 18 loses the power to rotate, and the rotating plate 18 stops rotating. Then, during the process of the lamp tube 4 continuing to rotate, the cleaning plate 34 on the outer side of the lamp tube 4 and the rotating plate 18 abuts against each other, causing 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 threadedly penetrated through the second connecting plate 35, during the process of the second connecting plate 35 moving downward, the second threaded rod 36 drives the fifth gear 39 to rotate, and 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, and the glass protective cover in the lamp tube 4 is located on the upper side of the cleaning plate 34. When the cleaning plate 34 is moved upward, the second threaded rod 36 is threadedly penetrated by the second connecting plate 35, and the fifth gear 39 is driven by the second threaded rod 36 to rotate, and 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, and the brush on the outside of the cleaning plate 34 is against the glass protective cover, and the cleaning plate 34 is still in a rotating state, so as to form a 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; In 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.

[0017] like Fig.11 A third threaded rod 42 is fixedly connected to the lower side of the lamp tube 15, and the third threaded rod 42 is threadedly inserted into the lamp tube 4, and a one-way bearing 41 is fixedly connected to the lower side of the third threaded rod 42, and a second connecting ring 44 is slidably connected to the outer side of the one-way bearing 41, and a plurality of fifth connecting rods 38 are fixedly connected to the lower side of the second connecting ring 44, and a bottom plate 43 is fixedly connected to the lower side of the one-way bearing 41; 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 opened with through holes connected to the cavity, wherein the inner wall of the upper through hole is engraved with threads 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 the focusing adjustment is required, 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 Fig.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 all the time. 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, which changes the focusing effect of the lamp tube 15 and reduces the phenomenon of dimming of the brightness of the lamp tube 15 from the lamp tube 4. This is a function of the LED lighting lamp itself, so it will not be redundantly described. It should be emphasized here that in this solution, the adjustment of the LED lamp angle, the cleaning of the glass protective cover and the 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 is rotated to 180 degrees. In this process, the upper end diameter of the lamp tube 4 is larger, so the round rod 19 will be squeezed, and the cleaning plate 34 will not touch the round rod 19 when it rotates to the upper side during this process. When the focusing adjustment is performed, the lamp tube 4 is restored to the initial position, that is, in this solution. Figure 1 In the state shown, the upper end of the lamp tube 4 will not rotate downward during the process, so cleaning the glass protective cover and focusing adjustment are related and do not interfere.

[0018] A method for using an LED lighting fixture with adjustable lighting angle comprises the following steps: S1, the base 1 is fixedly installed in the working position, and the lamp tube 15 is electrically connected to the corresponding control switch, and the lamp tube 15 is turned on and the brightness of the lamp tube 15 is adjusted by the control switch, thereby starting the corresponding lighting operation; S2, during the lighting process, start the motor 20 to adjust the lighting angle; S3, make the glass protective cover in the lamp tube 4 face the base 1, and clean the glass protective cover in the lamp tube 4; S4. Make the bottom of the lamp tube 4 face the base 1, adjust the position of the lamp tube 15 in the lamp tube 4, and then adjust the focusing effect.

[0019] In the present invention, when the device as a whole is in use, the base 1 is installed at the corresponding working position by means of bolts 2, and the lamp tube 15 is electrically connected to the corresponding control switch, and the lamp tube 15 is turned on and the brightness of the lamp tube 15 is adjusted by the control switch, thereby starting the corresponding lighting operation. The above are all prior arts and no redundant description is given; 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 slidably connected, and the first threaded rod 14 and the threaded ring 6 are threadedly connected, 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 third gear 9 and the fourth gear 11 to drive the first threaded rod 14 fixedly installed on the outside of the second connecting rod 13. The second gear 7 rotates, and the second gear 7 rotates through the second connecting rod 13 and the fixed rod 5, and the fixed rod 5 drives the lamp tube 4 to rotate around the fixed rod 5, thereby completing the adjustment operation of the lighting angle of the lamp tube 15, and in this process, under the action of the rotating fourth gear 11, the heat dissipation rod 10 is caused to rotate, and the heat dissipation rod 10 drives the heat dissipation plate 12 to rotate, so that the heat dissipation plate 12 generates cooling wind that can be blown to the lamp tube 4, thereby reducing the temperature of the lamp tube 15 and the lamp tube 4, thereby making the lamp tube 15 and the lamp tube 4 always in a good working state, thereby increasing the service life of the lamp tube 15; 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. During the rotation of the shaft 21, the shaft 21 drives the sleeve 30 and the square rod 31 to rotate through the telescopic cylinder 32, and the square rod 31 drives the rotating plate 18 and the cleaning plate 34 to rotate. During this process, the rotation of the cleaning plate 34 can also generate cooling wind, thereby reducing the temperature outside the lamp tube 4, thereby further putting the lamp tube 15 in a good working condition. When the lamp tube 15 performs lighting work for a long time, a certain amount of dust will accumulate on the outside of the glass protective cover installed in the lamp tube 4, thereby causing the lighting brightness of the lamp tube 15 emitted from the lamp tube 4 to become lower. At this time, the motor 20 can be started again. The machine 20 drives the lamp tube 4 to rotate as a whole until the lamp tube 4 and the cleaning plate 34 are opposite to each other, that is, the glass protective cover in the lamp tube 4 is located on the upper side of the cleaning plate 34. During this process, the lamp tube 4 and the round rod 19 are against each other, which will cause the round rod 19 to move downward relative to the base 1. The round 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 power to rotate, and the rotating plate 18 stops rotating. Then, the lamp tube 4 continues to rotate. During the continuous rotation, the cleaning plate 34 on the outside of the lamp tube 4 and the rotating plate 18 abuts against each other, causing 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 threadedly penetrated by the second connecting plate 35, during the downward movement of the second connecting plate 35, the second threaded rod 36 drives the fifth gear 39 to rotate, and 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 tube 4 is located on the upper side of the cleaning plate 34, there is a certain gap between the end of the lamp tube 4 and the glass protective cover. When the glass protective cover moves to the cleaning plate 3 4, the cleaning plate 34 loses the restriction of the lamp tube 4, thereby causing the cleaning plate 34 to move upward. During the upward movement of the cleaning plate 34, since the second threaded rod 36 is threadedly penetrated by the second connecting plate 35, during the upward movement of the second connecting plate 35, the second threaded rod 36 drives the fifth gear 39 to rotate, and 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, and the brush on the outside of the cleaning plate 34 and the glass protective cover are against each other, and the cleaning plate 34 is still in a rotating state, thereby forming a cleaning effect on the glass protective cover, thereby enabling the brightness of the irradiated light emitted by the lamp tube 15 from the lamp tube 4 to be always in a good working state; When the lamp tube 15 and the lamp holder 4 are working, when the lighting effect needs to be adjusted, that is, when the focusing adjustment needs to be performed, the motor 20 is started to rotate the lamp holder 4 as a whole after the angle adjustment, so that the lamp holder 4 returns to the initial position, even if the device as a whole is in Figure 1 The connection phenomenon, in Fig.12 In the process, even if the device as a whole changes from the Z state back to the X state, unlike when the glass protective cover is cleaned, during 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 all the time. 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 is changed, that is, the position of the lamp tube 15 relative to the reflector is changed, thereby changing the focusing effect of the lamp tube 15 and reducing the phenomenon of dimming of the brightness of the lamp tube 15 emitted from the lamp tube 4. This is a function of the LED lighting itself, so it will not be redundantly described.
