A height-adjustable lighting street lamp

Abstract

The present invention discloses a height-adjustable lighting street lamp, specifically an LED street lamp, which comprises: a lamp pole, on which a tooth groove is arranged; a lamp cap cover, on which a movable wick and a sliding seat slidably connected to the lamp pole are arranged, and a fixed reflector for holding the movable wick is symmetrically arranged on the sliding seat; and a linkage mechanism, which comprises a planetary reduction gear set rotatably connected to the sliding seat and respectively coupled to the tooth groove and the movable wick. In the present invention, when the sliding seat is slid along the lamp pole, the planetary reduction gear set will drive the movable wick to move in the same direction, so that the distance between the movable wick and the fixed reflector changes. When the position of the sliding seat is relatively high, the distance between the movable wick and the fixed reflector is short, so as to gather light to ensure the degree of irradiation, and when the position of the sliding seat is relatively low, the distance between the movable wick and the fixed reflector increases, so as to reduce the gathering of light, so as to irradiate a larger range at a low position.

Technical Field

[0001] The invention relates to the technical field of LED street lamps, and in particular to a lighting street lamp with adjustable height. Background Art

[0002] Street lights are part of infrastructure construction projects and are mainly installed on both sides of roads to illuminate the roads. Height-adjustable street lights are set up for special sections of roads, making it easy to set them according to different lighting needs.

After the rotation, the lamp pole no longer blocks the road to avoid affecting the passage of pedestrians. At the same time, during the descent process, the lamp pole is also flipped 90 degrees through the rotating mechanism, so that the lamp pole changes from a horizontal state to a vertical state, and after the lamp pole is in a vertical state, the unlocking mechanism is driven to passively unlock the lamp head from the lamp pole to complete the pre-disassembly, so that subsequent staff can directly remove the lamp head, which greatly improves the disassembly efficiency of the lamp head.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] like Figure 1-8 As shown, a height-adjustable lighting street lamp comprises:

[0038] A lamp post 3, on which a tooth groove 30 is provided;

[0039] A lamp cap cover 1 is provided with a movable lamp core 11 and a sliding seat 21 slidably connected to the lamp pole 3, and a fixed reflector 32 for holding the movable lamp core 11 is symmetrically provided on the sliding seat 21;

[0040] The linkage mechanism 2 includes a planetary reduction gear set 22 which is rotatably connected to the sliding seat 21 and is respectively coupled to the tooth groove 30 and the moving wick 11;

[0041] The sliding seat 21 slides with the lamp pole 3 to drive the movable lamp core 11 to slide along the moving direction of the sliding seat 21 through the planetary reduction gear set 22, so that the irradiation range of the lamp cap cover 1 changes.

[0042] Specifically, the sliding seat 21 is slidably connected to the lamp pole 3, the mobile wick 11 is slidably connected to the sliding seat 21, and the fixed reflector 32 is used to reflect the light of the mobile wick 11 to increase the light intensity. The sliding seat 21 is rotatably connected with a planetary reduction gear set 22, the input end of the planetary reduction gear set 22 is coupled to the tooth groove 30, and the output end of the planetary reduction gear set 22 is coupled to the mobile wick 11. During the installation process, the lamp head cover 1 will be slid according to the height of the vegetation to avoid obstruction to the vegetation, and in the process of sliding downward (the downward movement is the bottom of the lamp pole 3), the lamp head cover 1 will be slid downward to avoid obstruction to the vegetation. During the process, the planetary reduction gear set 22 will drive the moving wick 11 to move downward as it slides, so that the distance between the moving wick 11 and the fixed reflector 32 increases. At this time, the light irradiated by the moving wick 11 to the fixed reflector 32 is reduced, while the diffusion range is increased to match the lowered height of the lamp head cover 1, thereby achieving the expansion of the lighting range at a low position without significantly affecting the lighting quality, and the lamp head cover 1 that is not obstructed by vegetation can continue to rise as required. At this time, the distance between the moving wick 11 and the fixed reflector 32 is shorter to gather light to ensure the degree of illumination.

[0043] Furthermore, the movable lamp 11 is an LED lamp.

[0044] In the above technical solution, when the sliding seat 21 slides along the lamp pole 3, the planetary reduction gear set 22 will drive the moving wick 11 to move in the same direction to change the distance between the moving wick 11 and the fixed reflector 32. When the position of the sliding seat 21 is relatively high, the distance between the moving wick 11 and the fixed reflector 32 is shorter to gather light to ensure the degree of illumination. When the position of the sliding seat 21 is relatively low, the distance between the moving wick 11 and the fixed reflector 32 is increased to reduce the gathering of light, thereby illuminating a larger range at a low position.

[0045] As an embodiment provided by the present invention, a sliding seat 21 is slidably connected to a sliding frame 12, the moving wick 11 is arranged on the sliding frame 12, a second transmission belt 24 is arranged on the sliding seat 21, the second transmission belt 24 is connected to the sliding frame 12 through a connecting rod 241, and the second transmission belt 24 is driven to rotate by a planetary reduction gear set 22;

[0046] The planetary reduction gear set 22 includes a sun drive gear 221 rotatably connected to the sliding seat 21 and a fixed outer gear ring 223 fixed to the sliding seat 21, planetary gears 222 are arranged in a circular array between the fixed outer gear ring 223 and the sun drive gear 221, a planetary retainer 2221 is arranged on the planetary gears 222, and the second transmission belt 24 is coupled to the planetary retainer 2221.

[0047] Specifically, a locking screw 211 for locking is provided on the sliding seat 21, and the sun driving gear 221 passes through the sliding seat 21 and rotates along the sliding seat 21. One end of the sun driving gear 221 is coupled to the tooth groove 30, and the other end extends out of the sliding seat 21 and is coaxially arranged with the fixed outer gear ring 223. A planetary gear 222 is arranged in a circumferential array between the fixed outer gear ring 223 and the sun driving gear 221. A planetary holder 2221 is provided on the planetary gear 222. A reduction device is provided between the planetary holder 2221 and the sun driving gear 221. A coupling is rotatably connected to the sliding seat 21. The second transmission belt 24 is rotatably connected to the sliding seat 21 through the coupling shaft, and the coupling shaft is coupled to the planetary holder 2221. When the height is adjusted, the lamp cover 1 is driven to slide, so that the sun drive gear 221 on the sliding seat 21 is coupled to the coupling tooth groove 30 and rotates, and then the sun drive gear 221 drives the planetary gear 222 to rotate in the same direction with reduced speed, and the planetary gear 222 is coupled to the coupling shaft to rotate and drive the second transmission belt 24, thereby driving the sliding frame 12 to slide and change the moving wick 11 through the connecting rod 241, so as to change the distance between the moving wick 11 and the fixed reflector 32.

[0048] During the installation process, the lamp cover 1 will be slid according to the height of the vegetation to avoid obstruction of the vegetation. In the process of sliding downward, the planetary reduction gear set 22 will drive the mobile wick 11 to move downward as it slides, and the sun drive gear 221 on the sliding seat 21 couples the coupling tooth groove 30 and rotates, and then the sun drive gear 221 drives the planetary gear 222 to rotate in the same direction with reduced speed, and the planetary gear 222 couples the coupling shaft to rotate and drive the second transmission belt 24, thereby driving the sliding frame 12 to slide and change the mobile wick 11 through the connecting rod 241. At this time, the light irradiated by the mobile wick 11 to the fixed reflector 32 is reduced, and the diffusion range is increased to match the lowered height of the lamp cover 1, thereby achieving the expansion of the lighting range at a low position without significantly affecting the lighting quality, and the lamp cover 1 that is not obstructed by the vegetation can continue to be raised according to the selection needs. At this time, the distance between the mobile wick 11 and the fixed reflector 32 is shorter.

[0049] As an embodiment provided by the present invention, a double-sided reflector 31 is arranged between two fixed reflectors 32, and the double-sided reflector 31 is assembled at the following two stations:

[0050] First station: two ends of the double-sided reflector 31 are respectively attached to two fixed reflectors 32 to form a "C"-shaped reflective surface to gather light;

[0051] Second station: the double-sided reflector 31 moves with the sliding frame 12 , and a reflecting space is formed between the double-sided reflector 31 and the fixed reflector 32 , so that the light is reflected to the top of the lamp cap cover 1 .

[0052] Specifically, a double-sided reflector 31 is arranged between the two fixed reflectors 32. Both sides of the double-sided reflector 31 are reflective surfaces that can reflect light. When the lamp cover 1 is in a high position, the distance between the movable wick 11 and the double-sided reflector 31 is relatively close. At this time, the double-sided reflector 31 is in the first position. The two ends of the double-sided reflector 31 are respectively attached to the two fixed reflectors 32 to form a "C"-shaped reflective surface to gather light. When the lamp cover 1 is restricted and in a low position, the movable wick 11 is 1 and the double-sided reflector 31 increases, and at this time the double-sided reflector 31 is switched to the second working position, so that a distance is generated between the double-sided reflector 31 and the fixed reflector 32, and the distance is the reflection space. The lamp cover 1 is made of transparent plastic, so that the light emitted by the movable wick 11 will be reflected toward the top of the lamp cover 1 along the reflection space, so as to illuminate the vegetation on the top of the lamp cover 1 when it is in a low position due to being restricted by the vegetation, so as to avoid the lower vegetation being unable to be illuminated and hindering the progress of pedestrians.

[0053] During the installation process, the lamp cover 1 will be slid according to the height of the vegetation to avoid obstruction of the vegetation. In the process of sliding downward, the sun drive gear 221 on the sliding seat 21 is coupled with the coupling tooth groove 30 and rotates, and then the sun drive gear 221 drives the planetary gear 222 to rotate in the same direction at a reduced speed, and the planetary gear 222 is coupled with the coupling shaft to rotate and drive the second transmission belt 24, so that the sliding frame 12 is driven to slide through the connecting rod 241 to change the moving wick 11. At this time, the light irradiated by the moving wick 11 to the fixed reflector 32 is reduced, and the diffusion range is increased to match the lowered height of the lamp cover 1, so as not to significantly affect the lighting. On the premise of improving quality, the illumination range is expanded at a low position. At the same time, the double-sided reflector 31 is switched to the second position, so that a distance is generated between the double-sided reflector 31 and the fixed reflector 32, and the distance is the reflection space. The lamp cover 1 is made of transparent plastic, so that the light emitted by the mobile wick 11 will be reflected to the top of the lamp cover 1 along the reflection space and the lamp cover 1 that is not blocked by vegetation can continue to rise according to the selection needs. At this time, the distance between the mobile wick 11 and the fixed reflector 32 is shorter. At this time, the double-sided reflector 31 is in the first position, and the two ends of the double-sided reflector 31 are respectively attached to the two fixed reflectors 32 to form a "C"-shaped reflective surface to gather light.

[0054] Furthermore, a spring 312 is provided between the sliding frame 12 and the double-sided reflector 31 , and a sliding column 311 slidably connected to the sliding frame 12 is provided on the double-sided reflector 31 .

[0055] The sliding column 311 is used to slidably connect the double-sided reflector 31 to the sliding frame 12. The spring 312 can ensure that the double-sided reflector 31 will not switch positions directly with the movement of the moving wick 11. Instead, when the moving wick 11 increases the distance between it and the fixed reflector 32, the spring 312 will keep the double-sided reflector 31 in the first position until the lamp head cover 1 is in a lower position (1700cm~2000cm). Then the extension stroke of the spring 312 will end, so that the double-sided reflector 31 will be switched to the second position as the moving wick 11 continues to move.

[0056] As an embodiment provided by the present invention, a diffusion cover 33 is symmetrically and movably arranged in the lamp cap cover 1, and the diffusion cover 33 is assembled at the following two stations:

[0057] The third station: two diffusion covers 33 are attached along the bottom of the lamp cover 1 to diffuse the light in the lower half;

[0058] Fourth station: two diffusion covers 33 are attached along the top of the lamp cap cover 1 and form a grid interlayer with the lamp cap cover 1 to diffuse the light in the upper half;

[0059] The third station and the fourth station of the diffusion cover 33 correspond to the second station and the first station of the double-sided reflective cover 31 respectively.

[0060] Specifically, the diffusion cover 33 is made of transparent frosted plastic and has the function of diffusely reflecting light to avoid glare and affect passers-by. A diffusion plate 34 is provided at the bottom of the lamp cover 1 (the bottom is the side facing the ground). The diffusion plate 34 is also made of transparent frosted plastic. When the lamp cover 1 is in a low position, the diffusion cover 33 is in the fourth position. The two diffusion covers 33 are attached along the top of the lamp cover 1. When light is generated at the top of the lamp cover 1, the two diffusion covers 33 will diffusely reflect the light at the top, and the diffusion plate 34 will diffusely reflect the bottom. At the same time, the two diffusion covers 33 and the top of the lamp cover 1 form a checkered interlayer to isolate the temperature when the lamp cover 1 is in a low position to avoid pedestrians from touching and getting burned.

[0061] When the lamp cover 1 is in the high position, the diffusion cover 33 is in the third position. At this time, the two diffusion covers 33 are attached along the diffusion plate 34 at the bottom of the lamp cover 1 to diffusely reflect light. At the same time, the moving wick 11 will be close to the top of the lamp cover 1 to dissipate heat.

[0062] During the installation process, the lamp cover 1 will be slid according to the height of the vegetation to avoid obstruction of the vegetation. In the process of sliding downward, the sun drive gear 221 on the sliding seat 21 couples the coupling tooth groove 30 and rotates, and then the sun drive gear 221 drives the planetary gear 222 to rotate in the same direction with reduced speed, and the planetary gear 222 couples the coupling shaft to rotate and drives the second transmission belt 24, thereby driving the sliding frame 12 to slide and change the moving wick 11 through the connecting rod 241. At this time, the light irradiated by the moving wick 11 to the fixed reflector 32 is reduced, and the diffusion range is increased to match the lowered height of the lamp cover 1, thereby achieving the expansion of the illumination range at a low position without significantly affecting the lighting quality. At the same time, the double-sided reflector 31 switches to the second working position, so that a gap is generated between the double-sided reflector 31 and the fixed reflector 32. , the spacing is the reflection space, the lamp cover 1 is made of transparent plastic, so that the light emitted by the mobile wick 11 will be reflected to the top of the lamp cover 1 along the reflection space, and the two diffusion covers 33 are fitted along the top of the lamp cover 1 to diffusely reflect the light on the top, and at the same time, the two diffusion covers 33 and the top of the lamp cover 1 form a checkered interlayer to isolate the temperature when the lamp cover 1 is in a low position, and the lamp cover 1 that is not hindered by vegetation can continue to rise according to the selection needs. At this time, the spacing between the mobile wick 11 and the fixed reflector 32 is shorter, and the double-sided reflector 31 is in the first position, and the two ends of the double-sided reflector 31 are respectively fitted with two fixed reflectors 32 to form a "C"-shaped reflective surface to gather light, and the diffusion cover 33 is in the third position, and the two diffusion covers 33 are fitted along the diffuse plate 34 at the bottom of the lamp cover 1 to diffusely reflect light.

[0063] Furthermore, the diffusion cover 33 moves with the operation of the planetary reduction gear set 22, and magnetic suction parts 331 are provided at both ends of the diffusion cover 33 to attract each other and delay the separation of the two diffusion covers 33, so that the position of the diffusion cover 33 is switched until the lamp holder cover 1 is at a lower position (1700cm~2000cm).

[0064] As an embodiment provided by the present invention, a scroll shaft 231 is rotatably connected to the sliding seat 21, a first transmission belt 23 is arranged between the scroll shaft 231 and the planetary reduction gear set 22, and an elastic pulling strip 232 is arranged between the scroll shaft 231 and the diffusion cover 33;

[0065] A pulling member 332 is disposed on the sliding seat 21 , and the pulling member 332 is used to pull the diffusion cover 33 to switch from the fourth station to the third station.

[0066] Specifically, a scroll shaft 231 is rotatably connected to the sliding seat 21, a first transmission belt 23 is sleeved between the sun drive gear 221 of the planetary reduction gear set 22 and the scroll shaft 231, and an elastic pulling strip 232 is provided between the scroll shaft 231 and the diffusion cover 33. When the sliding seat 21 slides downward, the scroll shaft 231 rotates with the rotation of the sun drive gear 221 to pull the diffusion cover 33 through the elastic pulling strip 232. The pull strip 232 will be gradually tightened until the suction force of the magnetic part 331 is overcome, so as to pull the diffusion cover 33 from the third station to the fourth station in a short time. When the sliding seat 21 moves upward, the elastic pull strip 232 will gradually relax, and the pulling member 332 provided on the sliding seat 21 will be tensioned in the fourth station, so that when the elastic pull strip 232 is gradually relaxed, the tensioned pulling member 332 pulls away the magnetic part 331, so as to switch the station of the diffusion cover 33 in a short time.

[0067] Furthermore, a limiting plate 121 is provided on the sliding frame 12 , and the limiting plate 121 is used to guide the elastic pulling strip 232 .

[0068] During the installation process, the lamp cover 1 will be slid according to the height of the vegetation to avoid obstruction of the vegetation. In the process of sliding downward, the sun drive gear 221 on the sliding seat 21 couples the coupling tooth groove 30 and rotates, and then the sun drive gear 221 drives the planetary gear 222 to rotate in the same direction with reduced speed, and the planetary gear 222 couples the coupling shaft to rotate and drives the second transmission belt 24, thereby driving the sliding frame 12 to slide and change the moving wick 11 through the connecting rod 241. At this time, the light irradiated by the moving wick 11 to the fixed reflector 32 is reduced, and the diffusion range is increased to match the lowered height of the lamp cover 1, thereby achieving the expansion of the illumination range at a low position without significantly affecting the lighting quality. At the same time, the double-sided reflector 31 switches to the second working position, so that a spacing is generated between the double-sided reflector 31 and the fixed reflector 32, and the spacing is the reflection space. The lamp cover 1 is made of transparent plastic, so that the light emitted by the moving wick 11 will be reflected to the top of the lamp cover 1 along the reflection space, and rolled The moving shaft 231 rotates with the rotation of the sun drive gear 221, and pulls the diffuser 33 through the elastic pull strip 232, so that the two diffusers 33 fit along the top of the lamp cover 1 to diffusely reflect the light on the top. At the same time, the two diffusers 33 and the top of the lamp cover 1 form a checkered interlayer to insulate the temperature when the lamp cover 1 is in a low position, and the lamp cover 1 that is not blocked by vegetation can continue to rise according to the selection needs. At this time, the moving wick 11 and the fixed reflector 3 2, the double-sided reflector 31 is in the first position, and the two ends of the double-sided reflector 31 are respectively attached to the two fixed reflectors 32 to form a "C"-shaped reflective surface to gather light. At this time, the elastic pulling strip 232 will gradually relax, and the pulling member 332 provided on the sliding seat 21 will be tensioned in the fourth position, pulling open the magnetic attraction part 331, so as to switch the diffusion cover 33 to the third position in a short time. At this time, the two diffusion covers 33 are attached along the diffusion plate 34 at the bottom of the lamp cover 1 to diffusely reflect light.

[0069] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
