Description

Technical Field

[0001] The present invention relates to the field of tree lighting lamps, and in particular to a tree lighting lamp capable of preventing leaf accumulation. Background Art

[0002] Landscape lighting enhances a city's image and prosperity, vividly and uniquely highlighting its character. Urban landscape and nightscape lighting, using landscape trees as a vehicle, is also a driving force behind the creation of new urban aesthetics and spatial value. To enrich the lives of urban residents at night, many cities have built numerous plazas and parks to facilitate their activities. Furthermore, to enhance the nighttime atmosphere, tree lighting is often installed, which also provides lighting.

[0003] In contrast, Chinese invention patent publication number CN111981350A discloses a self-cleaning LED tree light, relating to the technical field of outdoor lighting. The invention comprises a lamp body; a lampshade is provided on the upper surface of the lamp body; side panels are fixedly connected to opposite outer walls of the lamp body; screws are rotatably connected to the lower surfaces of the side panels; guide rails are connected to the upper surfaces of the side panels; the screws are equipped with screw nuts; a U-shaped block is fixed to the screw nuts; a slider is equipped with a slider; the slider is rotatably connected to a rotating shaft; one end of the rotating shaft is connected to a lever, and the other end is connected to a connecting rod; one end of the lever is located between the two side walls of the U-shaped block, and the width of the lever is less than the distance between the two side walls of the U-shaped block; a cleaning plate is rotatably connected to one side of the connecting rod; one end of the cleaning plate is rotatably connected to another connecting rod; and a plurality of scrapers are fixedly connected to the lower surface of the cleaning plate.

[0004] By comparing the existing technology and the comparative scheme, it can be seen that the current cleaning methods of the control tree lights all rely on external equipment. The exposure of the external motor itself and the limitation of materials cause the tree lights and the cleaning equipment attached thereto to occupy a large area and have a high cost. The control tree lights are cleaned indiscriminately when started, and real-time adaptive cleaning cannot be performed according to the obstruction of the tree lights. In addition, the external appearance is not high, resulting in low practicality. Summary of the Invention

[0005] The object of the present invention is to provide a tree lighting lamp that can prevent leaves from piling up in order to solve the above problem.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] A tree lighting lamp for preventing leaf accumulation includes a lighting mechanism for lighting, a toggle mechanism for removing fallen leaves from the top of the lighting mechanism, a ventilation mechanism for ensuring heat dissipation of the lighting mechanism, and a detection mechanism. The toggle mechanism is sleeved on the outside of the lighting mechanism, the ventilation mechanism is mounted on the toggle mechanism, and the detection mechanism is mounted inside the lighting mechanism.

[0008] The toggling mechanism includes an external rotating cylinder, which is rotatably connected to the outside of the lighting mechanism. Inside the external rotating cylinder, it is cooperated with the detection mechanism through a power component.

[0009] The ventilation mechanism includes an air inlet hole and an air outlet plate. A number of air inlet holes are evenly formed on the top surface of the external rotating cylinder. An inner retaining ring is installed between the inside of the external rotating cylinder and the lighting mechanism. A number of air outlet plates are evenly arranged on the outer circumferential end surface of the external rotating cylinder. A central channel is provided corresponding to the lighting mechanism inside the inner retaining ring.

[0010] The detection mechanism includes a follower blade and a fixed rod. The follower blade is fixedly connected inside the lighting mechanism. The fixed rod is installed inside the central channel. A follower blade is installed on the fixed rod. The follower blade and the fixed rod are connected through an elastic reset component in a cooperative manner, and a contact point is installed between the elastic reset components.

[0011] Preferably: The top surface of the inner retaining ring is fixedly connected to the top surface of the inner wall of the external rotating cylinder, and the height of the inner retaining ring is less than the height inside the external rotating cylinder.

[0012] Preferably: The horizontal plane of the air outlet plate is lower than the bottom of the inner retaining ring.

[0013] Preferably: A number of toggle rods are evenly formed at the upper end of the external rotating cylinder.

[0014] Preferably: The lighting mechanism includes a lamp body and a lamp housing. The lamp body and the central channel are connected through a bracket, and the central channel is formed between the lamp housing and the lamp body.

[0015] Preferably: The air outlet plate is connected to the external rotating cylinder through a pin shaft, and the air outlet plate opens outwards.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The inclined lighting mechanism drives the inclined external rotating cylinder, so that the air outlet plate near the bottom on the external rotating cylinder opens, and the air outlet plate near the upper side closes. Utilize the passive heat dissipation formed by the lighting mechanism itself when it is turned on, so that the external rotating cylinder, the inner retaining ring, the central channel, and the air outlet plate form the flow of cooling air, thereby driving the follower blade to rotate. After the follower blade rotates, it has an upward force, so that the two contact points inside the follower blade are separated, and when the leaves block the surface of the lighting mechanism, the air inlet end of the external rotating cylinder is blocked, and the device cannot form a complete air flow path, then the follower blade loses the wind energy and is pulled back to the fixed rod by the elastic reset component, so that the two contact points contact, making the power component inside the external rotating cylinder energized, driving the external rotating cylinder to rotate, and the external rotating cylinder rotates to drive the toggle rods at the upper end to rotate to sweep the leaves covering the lighting mechanism, avoiding the lighting mechanism being blocked and affecting the irradiation effect and causing overheating damage.

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] The present invention will be further described below in conjunction with the accompanying drawings: Example 1

[0029] like Figures 1 - 5 As shown, a tree lighting lamp for preventing leaf accumulation includes a lighting mechanism 4 for lighting, a toggle mechanism 2 for removing fallen leaves from the top of the lighting mechanism 4, a ventilation mechanism 3 for ensuring heat dissipation of the lighting mechanism 4, and a detection mechanism 5. The toggle mechanism 2 is sleeved on the outside of the lighting mechanism 4, the ventilation mechanism 3 is installed on the toggle mechanism 2, and the detection mechanism 5 is installed inside the lighting mechanism 4.

[0030] The toggle mechanism 2 includes an external rotating drum 21, which is rotatably connected to the outside of the lighting mechanism 4. The interior of the external rotating drum 21 cooperates with the detection mechanism 5 through a power component. The power component includes a gear ring 23 and a gear 24. The two gears 24 are equipped with a motor (not shown) via a driving gear. The exterior of the gear 24 meshes with the gear ring 23 installed on the inside of the external rotating drum 21. When the motor is energized, the gear ring 23 and gear 24 drive the external rotating drum 21 to rotate, thereby causing the toggle lever 22 to drive the fallen leaves to fall.

[0031] The ventilation mechanism 3 includes an air inlet hole 31 and an air outlet plate 32. A number of air inlet holes 31 are evenly formed on the top surface of the outer rotating cylinder 21. An inner retaining ring 33 is installed between the inside of the outer rotating cylinder 21 and the lighting mechanism 4. A number of air outlet plates 32 are evenly arranged on the outer circumferential end surface of the outer rotating cylinder 21. A central passage 44 is provided corresponding to the lighting mechanism 4 inside the inner retaining ring 33. The outer rotating cylinder 21, the inner retaining ring 33, and the central passage 44 form a U-shaped passage, so as to avoid damage to the internal electrical components caused by rainwater infiltrating from the outer rotating cylinder 21 while ensuring the flow of gas.

[0032] The detection mechanism 5 includes a follower blade 51 and a fixed rod 52. The follower blade 51 is fixedly connected inside the lighting mechanism 4. The fixed rod 52 is installed inside the central passage 44. The follower blade 51 is installed on the fixed rod 52. The follower blade 51 and the fixed rod 52 are connected by a tension spring 53, and a contact 54 is installed between the tension springs 53. When the follower blade 51 is lifted by wind energy, the two contacts 54 are separated. When the follower blade 51 loses wind energy and falls, the two contacts 54 cooperate to contact, so as to energize the motor.

[0033] In this embodiment: The top surface of the inner retaining ring 33 is fixedly connected to the top surface of the inner wall of the outer rotating cylinder 21. The height of the inner retaining ring 33 is less than the height inside the outer rotating cylinder 21, so as to form a gap for gas passage between the outer rotating cylinder 21 and the inner retaining ring 33.

[0034] In this embodiment: The horizontal plane of the air outlet plate 32 is lower than the bottom of the inner retaining ring 33, making it easier for the internal hot air to be discharged.

[0035] In this embodiment: A number of dial rods 22 are evenly formed at the upper end of the outer rotating cylinder 21. When the dial rods 22 are driven by the outer rotating cylinder 21, they can take the fallen leaves away.

[0036] In this embodiment: The lighting mechanism 4 includes a lamp body 43 and a lamp housing 41. The lamp body 43 and the central passage 44 are connected by a bracket, and the central passage 44 is formed between the lamp housing 41 and the lamp body 43. A heat sink 42 is installed on the bottom surface of the lamp body 43. After the heat sink 42 generates heat, the internal pressure increases. When the air passage is unobstructed, the internal high pressure takes the hot air out and at the same time drives the follower blade 51 to rotate.

[0037] In this embodiment: The air outlet plate 32 is connected to the outer rotating cylinder 21 through a pin shaft. The air outlet plate 32 opens outwards. When the outer rotating cylinder 21 is in an inclined state, the air outlet plate 32 is affected by gravity. The air outlet plate 32 near the bottom opens, while the air outlet plate 32 at the top is closed by gravity, so as to prevent external rainwater from invading the inside of the outer rotating cylinder 21 and damaging the internal components.

[0038] Working principle: Under normal conditions, the device is installed on one side of a wall or a tree. By adjusting the angle of the adjustment base 1, the lamp body 43 is aligned with the tree for illumination. At this time, the air outlet plate 32 outside the outer rotating cylinder 21 is affected by gravity, and the air outlet plate 32 near the bottom opens, while the air outlet plate 32 at the top is closed by gravity, thus preventing external rainwater from invading the inside of the outer rotating cylinder 21 and damaging the internal components. At the same time, when the lamp body 43 is turned on, the internal heat dissipation fin 42 dissipates heat. After the heat dissipation fin 42 heats up, the internal pressure increases. At this time, since there is no fallen leaf on the top surface of the lamp body 43, the inclined lighting mechanism 4 drives the inclined outer rotating cylinder 21, causing the air outlet plate 32 near the bottom of the outer rotating cylinder 21 to open and the air outlet plate 32 near the upper side to close. The passive heat dissipation formed by the lighting mechanism 4 when it heats up itself is utilized to form a heat dissipation channel between the outer rotating cylinder 21, the inner retaining ring 33, the central channel 44, and the air outlet plate 32. The high pressure formed by the heat dissipation fin 42 in the channel drives the formation of air flow in the channel, thereby driving the rotation of the follower blade 51. After the follower blade 51 rotates, it has the force to rise, causing the two contacts 54 inside the follower blade 51 to separate. When separated, the motor does not drive. And when the leaves block the surface of the lamp body 43, the air inlet hole 31 of the outer rotating cylinder 21 is blocked, and a complete air flow path cannot be formed inside the device. Then the follower blade 51 loses the wind energy and is pulled back to the fixed rod 52 by the elastic resetting member, causing the two contacts 54 to contact, enabling the motor inside the outer rotating cylinder 21. The motor drives the outer rotating cylinder 21 to rotate through the gear ring 23 and the gear 24. The rotation of the outer rotating cylinder 21 drives the rotation of the lever 22 at the upper end to sweep the leaves covering the lighting mechanism 4, preventing the lighting mechanism 4 from being blocked and affecting the illumination effect and causing overheating damage. After the fallen leaves are taken away, the internal air channel is unblocked again, the follower blade 51 is lifted again, and the contacts 54 are separated, so the outer rotating cylinder 21 stops rotating.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
