Description

Technical Field

[0001] This utility model relates to the field of LED floodlight technology, specifically to an LED floodlight with an adjustable illumination angle. Background Technology

[0002] LED floodlights are widely used lighting fixtures, often used alone in municipal facilities for illumination and decoration. Because the projection surface of LED floodlights is made of transparent glass, they are frequently subjected to collisions during transportation and installation. For LED floodlights with significant differences in the length-to-width ratio of the glass, the stress is low, making the glass prone to breakage.

[0003] In the prior art, a Chinese patent document with publication number CN211399478U was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: an LED floodlight, including a lamp body.

[0004] To address the frequent collisions during transportation and installation, and the issue of LED floodlights with large differences in glass aspect ratio causing low stress and easy glass breakage, existing technologies divide the projection surface into multiple projection zones. However, this method still results in situations where the LED floodlight becomes unusable after being mounted on a wall, leading to the inability to adjust its downward beam angle. Utility Model Content

[0005] The purpose of this invention is to provide an LED floodlight with an adjustable illumination angle to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An adjustable LED floodlight includes a suspension assembly, a connecting assembly fixedly mounted on the surface of the suspension assembly, an adjusting assembly movably mounted above the connecting assembly, and a floodlight snapped onto the surface of the suspension assembly.

[0008] The adjustment assembly includes an adjustment unit and a tensioning connection unit, wherein the adjustment unit is movably mounted on the surface of the suspension assembly.

[0009] A further improvement of the present invention is that the suspension assembly includes a suspension plate, the suspension plate has mounting grooves at four ends on its surface, and a snap-fit ​​ball rod is fixedly installed on the top of the suspension plate. The snap-fit ​​ball rod facilitates the auxiliary installation of the floodlight.

[0010] A further improvement of this utility model is that the connecting component includes a connecting rod fixedly installed on the surface of the suspension plate. One end of the connecting rod is inserted into an L-shaped rod, and a snap-fit ​​block is fixedly installed on the bottom surface of the L-shaped rod. By setting the connecting component, the floodlight can be snapped into place using the snap-fit ​​block, and the tilt angle of the L-shaped rod can be adjusted by adjusting the component under the action of the movable connection between the connecting rod and the L-shaped rod, so as to adjust the illumination angle of the floodlight.

[0011] A further improvement of this utility model is that the adjustment unit includes a threaded rod movably mounted on the surface of the suspension plate. A rotating wheel is fixedly mounted on one end of the threaded rod, and a threaded groove ring is threaded onto the surface of the threaded rod. By setting the adjustment unit, when the irradiation angle needs to be adjusted, the rotating wheel can control the rotation of the threaded rod to drive the threaded groove ring to move, thereby driving the tensioning connection unit to pull the L-shaped rod upward to adjust the downward irradiation angle.

[0012] A further improvement of this utility model is that the tensioning connection unit includes a connecting block fixedly installed on the surface of the screw groove ring. A buckle is installed through the surface of the connecting block, and a pull rope is wound around the surface of the buckle. By setting the tensioning connection unit, the L-shaped rod and the adjustment unit can be connected. Since the pull rope is more flexible than the support rod, it can adapt to the situation where the pull rope twists due to the change of angle during adjustment.

[0013] A further improvement of this utility model is that the floodlight includes a snap-fit ​​bracket that is snap-fitted to one end of a snap-fit ​​rod. A rear cover of the floodlight is movably mounted on the surface of the snap-fit ​​bracket. A floodlight lamp core is fixedly installed inside the rear cover of the floodlight. A front cover of the floodlight is snap-fitted to the surface of the rear cover of the floodlight. By setting the snap-fit ​​bracket, the floodlight can be hung without affecting the adjustment of its illumination angle.

[0014] A further improvement of this utility model is that: the other set of connecting blocks is installed on the L-shaped rod and connected by another set of buckles and the other end of the pull rope, and the floodlight rear cover and the snap-fit ​​block are snap-fitted together.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides an LED floodlight with an adjustable illumination angle. By setting a connecting component, the floodlight can be installed by snapping on the snap-fit ​​block. Under the action of the connecting rod and the L-shaped rod being movably connected, the tilt angle of the L-shaped rod can be adjusted by adjusting the component to adjust the illumination angle of the floodlight.

[0017] 2. This utility model provides an LED floodlight with an adjustable illumination angle. By setting an adjustment unit, when the illumination angle needs to be adjusted, the rotating wheel can control the rotation of the threaded rod to drive the screw groove ring to move, thereby driving the tensioning connection unit to pull the L-shaped rod upward to adjust the downward illumination angle.

[0018] 3. This utility model provides an LED floodlight with an adjustable illumination angle. By setting a tensioning connection unit, it can connect the L-shaped rod and the adjustment unit. At the same time, because the pull rope is more flexible than the support rod, it can adapt to the situation where the pull rope twists due to the change of angle during adjustment.

By setting the connecting assembly 2, the floodlight 4 can be snap-fitted onto the surface, and the tilt angle can be adjusted by the adjustment assembly 3 under the action of the movable connection, so as to adjust the illumination angle of the floodlight.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the connecting component 2 includes a connecting rod 21 fixedly installed on the surface of the suspension plate 11, an L-shaped rod 22 inserted into one end of the connecting rod 21, a snap-fit ​​block 23 fixedly installed on the bottom surface of the L-shaped rod 22, an adjusting unit including a threaded rod 31 movably installed on the surface of the suspension plate 11, a rotating wheel 32 fixedly installed on one end of the threaded rod 31, a threaded groove ring 33 threadedly installed on the surface of the threaded rod 31, and a tensioning connecting unit including a connecting block 34 fixedly installed on the surface of the threaded groove ring 33, a retaining ring 35 through the surface of the connecting block 34, and a pull rope 36 wound around the surface of the retaining ring 35. By setting the adjusting unit, when the irradiation angle needs to be adjusted, the rotating wheel 32 can control the threaded rod 31 to rotate, thereby driving the threaded groove ring 33 to move, which in turn drives the tensioning connecting unit to pull the L-shaped rod 22 upward to adjust the downward irradiation angle.

[0030] Example 3

[0031] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the floodlight 4 includes a snap-fit ​​bracket 41 that is snap-fitted to one end of the snap-fit ​​ball rod 13. A floodlight rear cover 42 is movably mounted on the surface of the snap-fit ​​bracket 41. A floodlight lamp core 43 is fixedly mounted inside the floodlight rear cover 42.

Another set of connecting blocks 34 is mounted on the L-shaped rod 22 and is connected by another set of buckles 35 and the other end of the pull rope 36. The floodlight rear cover 42 and the snap-fit ​​block 23 are snap-fitted together. By setting the pull rope 36, the L-shaped rod 22 and the adjustment unit can be connected. At the same time, because the pull rope 36 is more flexible than the support rod, it can adapt to the situation where the pull rope 36 will twist due to the change of angle during adjustment.

[0032] The working principle of an adjustable LED floodlight will be explained in detail below.

[0033] like Figure 1-5 As shown, when using the LED floodlight, screws are used to suspend it through the mounting slot 12 on the suspension plate 11.

[0034] When it is necessary to adjust the illumination angle, the threaded rod 31 can be rotated by holding the rotating wheel 32 to move the threaded ring 33 backward. Under the connection of the pull rope 36, the L-shaped rod 22 can be moved up and down, thereby realizing the rotation of one end of the connecting rod 21, and finally adjusting the angle at which the light can shine downward.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
