Description

Technical Field

[0001] The present application relates to the technical field of lighting devices, and in particular to a lampshade and a street lamp. Background Art

[0002] Good road lighting conditions can improve the city's investment environment and promote economic activities, especially in the night economy and tourism industry, the lighting effect of street lamps directly affects the tourists' experience and the city's attractiveness. Street lamps are the main source of urban night lighting, providing the necessary visibility for pedestrians and vehicles, thereby ensuring the safety and smoothness of night traffic.

[0003] The street lamp in the prior art is composed of a lamp body and a lamp pole, wherein the lamp body includes a lamp tube and a lampshade. The traditional lampshade is open-type, and from its appearance, the upper end is small and the lower end is large, and it is set in a cone shape, and its lower end is open to guide the light beam to the designed irradiation range. Since the lampshade is open-type, the lamp tube is exposed to the outside, and the lamp tube is easily subjected to external forces, which leads to the scrapping of the lamp tube. At the same time, rainwater and dust in the air are easy to invade or adhere to the lamp tube and the line, causing the line to age or short-circuit, which seriously shortens the life of the street lamp.

[0004] A Chinese patent with announcement number CN111174178B discloses a lampshade and a street lamp, comprising an upper cover body and a lower cover body, wherein a ferrule is arranged in the upper cover body, a guide body is arranged on the outer wall of the ferrule, the guide body is inclined, the lower end is away from the ferrule relative to the upper end, and a first concave surface concave inwardly is formed between the lower end of the ferrule and the lower end of the guide body; a connecting portion is arranged at the top end of the lower cover body, the top of the connecting portion is located in the ferrule and connected to the ferrule, the bottom of the connecting portion extends outwardly to form an extension portion, the extension portion is not provided with a first inclined body, the upper end of the first inclined body is away from the connecting portion relative to the lower end, the upper end of the first inclined body is connected to a second inclined body, the upper end of the second inclined body is close to the connecting portion relative to the lower end to form a vertex angle, the vertex angle is located in the first concave surface, the bottom surface of the lower cover body is located on the inner side of the second inclined portion, and the position where the side surface of the lower cover body is connected to the second inclined portion forms a first side angle, which is located in the upper cover body; a first through hole connecting the ferrule and the inside of the lower cover body is arranged on the connecting portion.

[0005] The above-mentioned lampshade and street lamp isolate rainwater on the outside of the lampshade through a sealed installation connection. However, the light source inside the lampshade will generate a lot of heat when working. The sealed installation connection method seriously affects the heat dissipation effect of the lampshade, thereby causing the light source to overheat. The overheated light source will reduce the luminous efficiency, resulting in a decrease in lighting brightness, affecting the lighting effect and visibility.

[0006] At this time, due to the shortened life of the light source and potential circuit failures, the lamp tube needs to be frequently maintained and replaced. However, one side of the lampshade in the above-mentioned lampshade and the street lamp is fixed to the lamp pole, and the same side is the connection between the lamp housing and the upper cover. When the street lamp needs to be repaired, the maintenance personnel must climb up to open the lampshade for inspection and maintenance, which not only increases the maintenance cost and workload, but also affects the overall operating efficiency of the street lamp system. Summary of the invention

[0007] In order to improve the heat dissipation effect of the lampshade and facilitate maintenance personnel to repair the street lamp, the present application provides a lampshade and a street lamp.

[0008] The lampshade and street lamp provided in this application adopt the following technical solutions:

[0009] A lampshade comprises an upper cover body and a lower cover body, wherein a ferrule is arranged in the upper cover body, and a connecting portion detachably connected to the ferrule is arranged at the top end of the lower cover body, a plurality of heat dissipation channels are arranged in the circumferentially connected cover body inner cavity of the ferrule, and a connecting through hole is opened along its own axial direction in the top connected inner cavity of the upper cover body, a fixed tube is coaxially arranged in the inner top wall connected to the connecting through hole, and a connecting tube is rotatably sleeved on the fixed tube through a bearing, a heat dissipation mechanism is arranged in the upper cover body, and the heat dissipation mechanism comprises a heat dissipation impeller fixedly sleeved on the connecting tube and a driving member driving the connecting tube to rotate, and when the driving member drives the connecting tube to rotate, the heat dissipation impeller synchronously rotates around the axial direction of the connecting tube, and dissipates the heat generated by the light source of the lamp tube out of the inner cavity of the lampshade through the heat dissipation channel.

[0010] By adopting the above technical solution, a ferrule with a heat dissipation channel and a heat dissipation mechanism are used, which significantly improves the heat dissipation effect of the lampshade. The heat dissipation channel is combined with a connecting through hole opened on the top of the upper cover body to communicate with the inner cavity, which not only facilitates installation and the passage of the line, but also ensures that the heat can be effectively dissipated, effectively preventing the light source from overheating, thereby ensuring the lighting effect and the life of the bulb. When the driving part in the heat dissipation mechanism is working, it will drive the connecting pipe and the heat dissipation impeller to rotate, forming forced convection, so that the heat generated by the light source of the lamp tube is quickly discharged from the inner cavity of the lampshade through the heat dissipation channel. This design greatly improves the heat dissipation efficiency and provides a guarantee for the long-term stable operation of the street lamp.

[0011] Optionally, the driving member includes a driving ring gear fixedly mounted on the connecting pipe, a driving gear meshing with the driving ring gear, and a driving rod driving the driving gear to rotate. The driving ring gear is located between the heat dissipation impeller and the inner top wall of the upper cover body, and the top end of the driving rod rotates through the inner top wall of the upper cover body and is driven to rotate by an external driving device.

[0012] By adopting the above technical solution, the driving gear is driven to rotate, and the rotation of the gear drives the driving gear ring and the connecting pipe to rotate together, thereby driving the heat dissipation impeller to rotate to achieve the heat dissipation function. This driving mechanism is simple and efficient in design, and can ensure the stable operation of the heat dissipation impeller, thereby effectively dissipating the heat in the lampshade.

[0013] Optionally, a support ring is provided at the bottom end of the fixed tube extending out of the connecting tube, and the support ring includes a fixed ring sleeved on the connecting tube, a connecting ring coaxially arranged with the outside of the fixed ring, and a plurality of support rods connected between the fixed ring and the connecting ring, wherein the plurality of support rods are distributed along the circumference of the fixed ring, and a rubber pad is provided on the outer ring of the connecting ring, and the rubber pad is provided in contact with the inner wall of the ring.

[0014] By adopting the above technical solution, the connecting ring and the fixed ring are connected by multiple support rods, which are evenly distributed along the circumference of the fixed ring, providing strong support force, which can improve the stability of the lampshade when the heat dissipation impeller rotates to dissipate heat. In addition, the rubber pad added to the outer ring of the connecting ring can compensate for the part error during the processing of the connecting ring through the property of elastic deformation, thereby pressing against the inner wall of the ferrule, further improving the stability of the lampshade when the heat dissipation impeller rotates to dissipate heat.

[0015] Optionally, a heat dissipation hole is provided on the ring corresponding to each heat dissipation channel, and each of the heat dissipation channels includes a first guide arc plate arranged on the outer wall of the ring and inclined downward, and a second guide arc plate arranged on the inner wall of the ring and inclined upward, the arc center of the first guide arc plate is located below itself, and the end of the first guide arc plate is matched and connected to the upper top wall of the heat dissipation hole, and the end of the second guide arc plate is matched and connected to the lower bottom wall of the heat dissipation hole.

[0016] By adopting the above technical scheme, a first guide arc plate is arranged outside the heat dissipation through hole and a second guide arc plate is arranged inside the heat dissipation through hole. The possibility of rainwater entering the lampshade from the heat dissipation through hole can be reduced through the guidance of the guide arc plates. In addition, the double guide arc plate structure enhances the hot air circulation effect, which is conducive to forming a heat flow circulation and exporting heat out of the lampshade faster, thereby improving the heat dissipation efficiency of the lampshade.

[0017] Optionally, an insect-proof net is provided at each of the heat dissipation holes.

[0018] By adopting the above technical solution, the setting of the insect-proof net can effectively prevent insects from entering the lampshade, thereby affecting the heat dissipation of the lampshade and the lighting effect of the street lamp, thereby extending the number of inspections and cleanings of the street lamp and increasing the service life of the street lamp.

[0019] Optionally, a plurality of plug-in frames are distributed circumferentially on the inner side wall of the ring, and a water-absorbing sponge is plugged into each of the plug-in frames.

[0020] By adopting the above technical solution, the absorbent sponge in the plug-in frame is used to absorb the condensed water droplets inside the lampshade to avoid electrical failures, and when the lampshade is inspected and cleaned, the absorbent sponge can be taken out of the plug-in frame, squeezed dry and then plugged into the plug-in frame for use.

[0021] A street lamp comprises a lamp post, a supporting tube which is lifted and lowered on the lamp post, and a lampshade as described in any one of items 1-6 connected to the end of the supporting tube away from the lamp post, a photovoltaic panel being installed on the top of the lamp post, a lifting assembly which is electrically connected to the photovoltaic panel being arranged inside the lamp post, and a controller being arranged on the side wall of the lamp post near the bottom.

[0022] By adopting the above technical solution, the lamp post has a lifting function, and the height of the lampshade can be easily adjusted, which greatly simplifies the maintenance operation process and reduces maintenance costs and workload. In addition, the photovoltaic panels store clean energy to increase power for the controller and electrical appliances, so that the lifting and lowering operation of the street lamp can be managed energy-efficiently and efficiently.

[0023] Optionally, the lifting assembly includes a screw rod which is vertically rotatable in the inner cavity of the lamp post and a motor which drives the screw rod to rotate. A vertical hole is provided in a support tube corresponding to the lamp post. The support tube passes through the lamp post through the vertical hole, and a portion of the support tube located inside the lamp post is rotatably sleeved on the screw rod through a thread.

[0024] By adopting the above technical solution, under the guide limit of the vertical hole, when the screw rod rotates, the support tube will move up and down along the screw rod, thereby realizing the lifting function of the lampshade.

[0025] Optionally, the support tube is provided with reinforcing ribs for supporting the side wall of the lamp post, and a plurality of balls for supporting the side wall of the lamp post are embedded on the side of the reinforcing ribs facing the side wall of the lamp post.

[0026] By adopting the above technical solution, the reinforcing ribs can effectively enhance the structural rigidity of the support tube and improve the stability of the support tube during the lifting process. The balls embedded on the side of the reinforcing ribs can reduce the friction resistance generated when the support tube collides with the side wall of the lamp post during the lifting process, thereby improving the smoothness of the lifting process.

[0027] Optionally, two side walls in each of the vertical holes that are opposite to each other in the horizontal direction are provided with rubber strips along their length direction, and the two oppositely arranged rubber strips are fitted together.

[0028] By adopting the above technical solution, when the support tube is raised and lowered in the vertical hole, the rubber strip can provide a certain sealing effect to prevent dust and moisture from entering the interior of the lamp post and reduce the possibility of the screw rusting. At the same time, the rubber strip can also play a certain buffering and supporting role for the support tube, enhancing its stability during the lifting process.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The use of a ferrule and heat dissipation mechanism with a heat dissipation channel significantly improves the heat dissipation effect of the lampshade. The heat dissipation channel is combined with a connecting through hole on the top of the upper cover body that is connected to the inner cavity. This not only facilitates installation and the passage of lines, but also ensures that heat can be effectively dissipated, effectively preventing the light source from overheating, thereby ensuring the lighting effect and the life of the bulb. When the driving part in the heat dissipation mechanism is working, it will drive the connecting pipe and the heat dissipation impeller to rotate, forming forced convection, so that the heat generated by the light source of the lamp tube is quickly discharged from the inner cavity of the lampshade through the heat dissipation channel. This design greatly improves the heat dissipation efficiency and provides a guarantee for the long-term stable operation of the street lamp;

[0031] 2. The drive gear rotates, and the gear rotation drives the drive gear ring and the connecting pipe to rotate together, and then drives the heat dissipation impeller to rotate to achieve the heat dissipation function. This driving mechanism is simple and efficient in design, which can ensure the stable operation of the heat dissipation impeller, thereby effectively dissipating the heat in the lampshade;

[0032] 3. The connecting ring and the fixed ring are connected by multiple support rods, which are evenly distributed along the circumference of the fixed ring, providing strong support force, which can improve the stability of the lampshade when the heat dissipation impeller rotates to dissipate heat. In addition, the rubber pad added to the outer ring of the connecting ring can compensate for the part error during the processing of the connecting ring through the elastic deformation property, thereby pressing against the inner wall of the ferrule, further improving the stability of the lampshade when the heat dissipation impeller rotates to dissipate heat.

[0050] Reference Figure 3In order to prevent dust and moisture from entering the interior of the lamp post 8, rubber strips 851 are fixedly arranged along the length direction of each vertical hole 85 on the two side walls opposite to each other in the horizontal direction. The two rubber strips 851 opposite to each other are fitted together and do not interfere with the normal lifting and lowering of the support tube 9.

[0051] Reference Figure 4 In order to improve the stability of the support tube 9 when it is lifted and lowered on the lamp post 8, a reinforcing rib 94 is fixedly provided on the support tube 9 to support the side wall of the lamp post 8, and a plurality of balls 941 are embedded on the side of the reinforcing rib 94 facing the side wall of the lamp post 8, and the plurality of balls 941 are supported on the side wall of the lamp post 8.

[0052] The implementation principle of a lampshade and a street lamp in the embodiment of the present application is as follows: Under normal working conditions, the photovoltaic panel 82 absorbs the electric energy converted by solar energy to supply the motor 842, and the output shaft of the motor 842 rotates to drive the screw 841 to rotate synchronously. The rotation direction of the screw 841 is to drive the support tube 9 to move upward along the guide of the vertical hole 85. However, at this time, the support tube 9 is already located at the connection between the top of the screw 841 and the output shaft, and the support tube 9 no longer moves. However, at this time, the first driven bevel gear 911 and the first active bevel gear 8421 are meshed, and the output shaft of the motor 842 rotates, thereby driving the transmission rod 91 meshed with the gear to rotate, and the rotation of the transmission rod 91 drives the driving rod 423 meshed with it to rotate. The driving rod 423 drives the driving gear 422 to rotate, and the driving gear 422 drives the driving gear ring 421 meshed with it to rotate synchronously. At this time, the heat dissipation impeller 41 starts to rotate, so that the heat generated by the light source of the lamp tube is quickly discharged from the inner cavity of the lampshade through the heat dissipation channel 3;

[0053] On the contrary, the maintenance personnel controls the motor 842 to reverse through the controller 83. At this time, the support tube 9 is automatically connected to the thread of the screw rod 841 due to gravity, and the output shaft of the motor 842 rotates to drive the support tube 9 to rotate synchronously. Under the limit of the vertical hole 85, the support tube 9 and the lampshade are lowered. At this time, the first driven bevel gear 911 is away from the first driving bevel gear 8421 and does not mesh with it. When the support tube 9 is lowered to a suitable height, the maintenance personnel stop the motor 842 through the controller 83, and then the lampshade and the lamp tube can be repaired and cleaned.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
