Description

Technical Field

[0001] This utility model relates to lighting fixtures, and more particularly to a self-cleaning tree floodlight. Background Technology

[0002] In fields such as garden landscape lighting, municipal greening illumination, and courtyard plant decoration, tree floodlights, as a type of directional lighting device, are widely used to highlight the aesthetic form of trees and enhance the layering of nighttime landscapes. Their core function is to project light at a specific angle, making the branches and leaves of trees appear clearly outlined and three-dimensional at night, meeting the dual needs of environmental decoration and functional lighting. In existing technology, tree floodlights typically consist of a transparent housing and a lighting mechanism. The transparent housing covers the outside of the lighting mechanism, protecting it from external rainwater, dust, insects, and other foreign objects, preventing corrosion and damage, while ensuring unobstructed light penetration for optimal lighting effects. However, in actual use, the outer surface of the transparent housing easily accumulates dust, fallen leaf debris, pollen, bird droppings, and other impurities. These impurities directly lead to a significant decrease in the light transmittance of the transparent housing, weakening the intensity of the projected light and reducing the illumination range, thus affecting the landscape lighting effect of the tree floodlight. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a self-cleaning tree floodlight that can ensure effective landscape lighting.

[0005] It has at least the following beneficial effects:

[0006] The light-emitting surface of the transparent cover facing the tree is convex and curved, making it easier for impurities falling on the surface to slide off under their own weight. This reduces the amount of impurities adhering to the light-emitting surface, thus ensuring the light transmittance of the transparent cover. This avoids the problem of weakened light intensity and reduced illumination range caused by a significant decrease in the light transmittance of the transparent cover, thereby guaranteeing the landscape lighting effect of the self-cleaning tree floodlight. Furthermore, the inclined lighting mechanism, combined with the transparent cover, directs the light obliquely upwards onto the tree. This ensures that the light is projected onto the tree normally to highlight its aesthetic form, and the curved self-cleaning design of the light-emitting surface further ensures the long-term stable landscape lighting effect of the tree floodlight.

[0028] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] refer to Figure 1 and Figure 2 This utility model discloses a self-cleaning tree floodlight, including an illumination mechanism 200 and a transparent cover 100. The illumination mechanism 200 is inclined. The transparent cover 100 covers the illumination mechanism 200 so that the light emitted by the illumination mechanism 200 passes through the transparent cover 100 and shines obliquely upwards onto the tree. The surface of the transparent cover 100 facing the tree is the light-emitting surface 110, which is convex arc-shaped so that impurities falling on the light-emitting surface 110 can slide off.

[0032] It should be explained that both the lighting mechanism 200 and the transparent housing 100 are set at an angle, so that the light emitted by the lighting mechanism 200 can shine obliquely upwards onto the trees, thereby achieving a better landscape lighting effect.

[0033] Understandably, the light-emitting surface 110 of the transparent cover 100 facing the tree is convex and curved, making it easier for impurities falling on the light-emitting surface 110 to slide off along the curved surface under their own gravity. This reduces the amount of impurities adhering to the light-emitting surface 110 of the transparent cover 100, thereby ensuring the light transmittance of the transparent cover 100. This avoids the problem of weakened light intensity and reduced illumination range caused by a significant decrease in the light transmittance of the transparent cover 100, thus ensuring the landscape lighting effect of the self-cleaning tree floodlight. On the other hand, the lighting mechanism 200 is tilted and works with the transparent cover 100 to illuminate the tree obliquely upwards. While ensuring that the light is projected normally onto the tree to highlight its aesthetic form, the curved self-cleaning design of the light-emitting surface 110 further ensures the long-term stable landscape lighting effect of the tree floodlight.

[0034] In this embodiment of the invention, the self-cleaning tree floodlight can achieve a more efficient self-cleaning effect in rainy weather. When rainwater falls onto the convex arc-shaped light-emitting surface 110 of the transparent cover 100, since the light-emitting surface 110 has no planar concave structure, the rainwater will not accumulate on the light-emitting surface 110, but will flow naturally along the inclined trajectory of the light-emitting surface 110, forming a continuous rainwater flow layer. For dust already attached to the light-emitting surface 110, the flowing rainwater will generate a scouring force on the attached dust, pushing the dust to slide off the light-emitting surface 110 with the water flow, preventing dust from adhering and accumulating on the light-emitting surface 110. For larger impurities such as leaves and petals, the rainwater will also wash away the larger impurities, allowing the impurities to detach from the light-emitting surface 110 more quickly and slide off with the rainwater. On the other hand, the convex arc-shaped light-emitting surface 110 makes the rainwater flow path smoother, ensuring that the rainwater can fully act on all areas of the light-emitting surface 110, achieving all-round cleaning of the light-emitting surface 110. In windy conditions, impurities attached to the light-emitting surface 110 will slide off the surface under the action of wind, achieving a self-cleaning effect of the light-transmitting cover. This ensures that the light transmittance of the transparent cover 100 is maintained within the design standard range, thereby ensuring the landscape lighting effect of the self-cleaning tree floodlight.

[0035] refer to Figure 2 and Figure 3 The transparent cover 100 is detachably connected to the lighting mechanism 200. Understandably, when the transparent cover 100 experiences wear and tear due to prolonged outdoor use, resulting in decreased light transmittance, or is damaged due to accidental impact, maintenance personnel do not need to disassemble the entire floodlight; they only need to remove the damaged transparent cover 100 from the lighting mechanism 200 and replace it with a new one, improving the convenience of maintenance for the transparent cover 100. On the other hand, when the lighting mechanism 200 malfunctions and requires repair or replacement, maintenance personnel can remove the transparent cover 100, providing unobstructed operating space for easy repair of the lighting mechanism 200. As one embodiment of this invention, the transparent cover 100 can be connected to the lighting mechanism 200 via a threaded connection. In another embodiment of this utility model, the lighting mechanism 200 includes a lamp bead assembly 210 and a housing 220. The lamp bead assembly 210 is disposed on the housing 220. A fastening groove is provided on the outer wall of the housing 220, and a fastening block is provided on the inner wall of the transparent cover 100. The fastening block can be fastened into the fastening groove. When it is necessary to disassemble the transparent cover 100, a pulling force is applied to the transparent cover 100 in a direction away from the housing 220, so that the fastening block on the transparent cover 100 disengages from the fastening groove on the housing 220, thereby completing the disassembly of the transparent cover 100. When it is necessary to install the transparent cover 100, first align the fastening block with the fastening groove, and then press the transparent cover 100 so that the fastening block on the transparent cover 100 is fastened into the fastening groove on the housing 220, thereby completing the installation of the transparent cover 100.

[0036] The LED assembly 210 is a common light-emitting component in the lighting industry. The LED assembly 210 includes a circuit board and multiple LEDs electrically connected to the circuit board, which will not be further described here. In this embodiment of the invention, a sealing ring is provided between the transparent cover 100 and the housing 220. It is understood that the sealing ring can seal the gap between the transparent cover 100 and the housing 220 to prevent rainwater, dew, dust, and other impurities in the outdoor environment from entering the interior of the transparent cover 100 through the gap between the cover and the housing 220. This prevents the LED assembly 210 from short-circuiting or being damaged due to moisture or dust accumulation, thus extending the service life of the LED assembly 210.

[0037] refer to Figures 1 to 3 The self-cleaning tree floodlight also includes a support member 300 and an adapter 400. The lower end of the support member 300 is inserted into the soil, and the lighting mechanism 200 is connected to the upper end of the support member 300 via the adapter 400. Understandably, the support member 300 provides a stable mounting base for the lighting mechanism 200. The lower end of the support member 300 can be inserted into the soil to prevent the lighting mechanism 200 from tipping over or shifting due to wind, minor impacts, or other external forces, ensuring that the lighting mechanism 200 always maintains its preset tilt angle and stably projects light onto the trees. The depth to which the support member 300 is inserted into the soil can be flexibly adjusted according to the tree height and lighting requirements, fixing the lighting mechanism 200 at a suitable height to meet the landscape lighting needs of different trees.

[0038] refer to Figure 2 and Figure 3 The adapter 400 includes a first part 410 and a second part 420. One end of the first part 410 is connected to the lighting mechanism 200, and the other end of the first part 410 is rotatably connected to one end of the second part 420, allowing the tilt angle of the lighting mechanism 200 to be adjusted. The other end of the second part 420 is connected to the upper end of the support member 300. It can be understood that the second part 420 of the adapter 400 is connected to the upper end of the support member 300, and the lighting mechanism 200 is rotatably connected to the second part 420 via the first part 410. When it is necessary to adjust the illumination angle of the lighting mechanism 200, the connection part of the first part 410 relative to the second part 420 can be rotated, causing the lighting mechanism 200 connected to the first part 410 to change its tilt direction, thereby changing the illumination direction of the lighting mechanism 200. The tilt angle of the lighting mechanism 200 can be adjusted to adapt to the illumination needs of different scenarios, improving the versatility of the self-cleaning tree floodlight. In this embodiment of the utility model, one end of the first part 410 is connected to the housing 220 of the lighting mechanism 200.

[0039] refer to Figure 3The self-cleaning tree floodlight also includes a fastening knob 440. The other end of the first part 410 is hinged to one end of the second part 420. The other end of the first part 410 has a through hole, and one end of the second part 420 has a stud 430, which passes through the through hole. The fastening knob 440 is threadedly connected to the stud 430, and the fastening knob 440 can press against the other end of the first part 410 to fix the first part 410 to the second part 420. In this embodiment, the other end of the first part 410 is hinged to one end of the second part 420 via a first hinge shaft, the axis of which coincides with the axis of the stud 430. It is understood that when the tilt angle of the lighting mechanism 200 needs to be adjusted, the fastening knob 440 can be loosened first. At this time, the first part 410 can rotate around the stud 430, thereby driving the lighting mechanism 200 to adjust its tilt angle. After the lighting mechanism 200 is adjusted to the target angle, tighten the fastening knob 440. The threaded engagement between the fastening knob 440 and the stud 430 generates axial pressure, pressing the fastening knob 440 onto the first part 410 to increase the friction between the first part 410 and the second part 420. Finally, the first part 410 is stably fixed onto the second part 420, ensuring that the lighting mechanism 200 does not loosen.

[0040] refer to Figure 1 and Figure 4 The support member 300 includes a mounting rod 320 and two insert rods 310. The lower ends of the two insert rods 310 are inserted into the soil, and the upper ends of the two insert rods 310 are connected to the mounting rod 320. The other end of the second part 420 is provided with a slot 421, in which the mounting rod 320 is inserted. The self-cleaning tree floodlight also includes a fastener. The other end of the second part 420 is provided with a threaded hole 422, which communicates with the slot 421. The fastener is threaded into the inner wall of the threaded hole 422 and pressed against the mounting rod 320. It can be understood that the lower ends of the two insert rods 310 of the support member 300 are inserted into the soil, which can enhance the stability of the support and avoid the problem of a single insert rod 310 easily tipping over. The upper ends of the two insertion rods 310 are connected to the mounting rod 320, which is inserted into the slot 421 of the second part 420, enabling quick assembly of the support member 300 and the adapter 400, and providing a stable mounting base for the lighting mechanism 200. Fasteners are threaded into the inner wall of the threaded hole 422 on the second part 420 and pressed against the mounting rod 320 in the slot 421, fixing the mounting rod 320 in place and preventing it from loosening or shifting. This ensures a stable connection between the support member 300 and the adapter 400, thereby preventing changes in the illumination angle of the lighting mechanism 200.

[0041] refer to Figure 5The self-cleaning tree floodlight also includes a support rod 330. A receiving groove is provided on the outer wall of the insertion rod 310. The lower end of the support rod 330 is hinged to the inner wall of the receiving groove, allowing the support rod 330 to be stored within the receiving groove and inserted into the soil. A torsion spring is provided between the support rod 330 and the insertion rod 310, forcing the support rod 330 to swing out of the receiving groove. Understandably, when the insertion rod 310 needs to be inserted into the soil, the worker first firmly grasps the outer wall of the insertion rod 310 and the upper end of the support rod 330, pressing the support rod 330 towards the receiving groove. This allows the support rod 330 to overcome the preload of the torsion spring and be fully retracted into the receiving groove on the outer wall of the insertion rod 310, ensuring that the support rod 330 does not protrude from the surface of the insertion rod 310. The worker then aligns the lower end of the insertion rod 310 with the preset installation position and applies vertical downward pressure, inserting the insertion rod 310 and the retracted support rod 330 into the soil. As the insertion rod 310 continues to penetrate deeper into the soil, once the predetermined insertion depth is reached, the worker gradually releases their grip on the support rod 330. At this point, the pressure of the soil on the support rod 330 weakens, and the spring force begins to release, pushing the support rod 330 outward from the storage groove around the hinge point until the support rod 330 and the insertion rod 310 form a stable angle, thus completing the installation and fixation of the insertion rod 310 in the soil. Under the action of the spring force, the support rod 330 can compress the soil, thereby increasing the friction between the insertion rod 310 and the soil, preventing the insertion rod 310 from being easily pulled out. When an upward pulling force is applied, causing the insertion rod 310 to move upward, the support rod 330, which is laterally embedded and tightly squeezed into the soil, will be subjected to stronger downward pressure and lateral friction caused by the soil. In other words, the soil hinders the movement of the support rod 330 with the insertion rod 310, and the increased friction between the support rod 330 and the soil further weakens the effect of the pulling force on the insertion rod 310, thereby enhancing the anti-pull-out effect of the insertion rod 310. Ultimately, this makes it difficult for the insertion rod 310 to be pulled out, ensuring that the insertion rod 310 can be firmly inserted into the soil.

[0042] In this embodiment of the utility model, the lower end of the tensioning rod 330 is hinged to the inner wall of the storage groove via the second hinge shaft. The torsion spring is sleeved on the second hinge shaft, and the two elastic arms of the torsion spring are respectively connected to the tensioning rod 330 and the inner wall of the storage groove. Further details will not be provided here.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
