Description

Technical Field

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

[0002] A floodlight is a lighting fixture that provides illumination to a surface that is higher than the surrounding environment. Also known as a spotlight, it can typically be aimed in any direction and has a structure that is unaffected by weather conditions. It is mainly used in large-area work sites, mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds to provide architectural lighting and beautification.

[0003] Current floodlights generally consist of a mounting base and a lamp body. For example, the utility model patent with publication number CN204328692U discloses an LED floodlight. This floodlight is equipped with a lamp body, a support device, a sealing ring, and a waterproof plug. The support device is connected to the lamp body by a hinge to support the lamp body, allowing the lamp body to be adjusted at an adjustable angle. Furthermore, the sealing ring and waterproof plug make the floodlight more waterproof and extend its service life.

[0004] However, while traditional floodlights are angle-adjustable, in practice, operators need to loosen all the bolts on both sides of the lamp body to release the lock before adjusting the angle. After adjusting the angle, the bolts on both sides of the lamp body need to be tightened again. During this process, operators need to hold the lamp body to prevent the angle from changing. This makes the angle adjustment process complicated and inconvenient, increasing the burden on operators. Furthermore, after multiple adjustments, the bolts are prone to loosening, which can cause the lamp body to sag, resulting in poor device reliability.

[0005] Based on this, an LED floodlight with adjustable illumination range is proposed. Utility Model Content

[0060] Lamp body fixing base 100;

[0061] The main LED light assembly 200 is mounted on the light body fixing base 100;

[0062] A rotary adjustment structure 300 is mounted on the lamp body fixing base 100 and connected to the main LED lamp body assembly 200 to drive the main LED lamp body assembly 200 and make it flip up or down.

[0063] Two sets of adjustable auxiliary lighting mechanisms 400 are provided, and the two sets of adjustable auxiliary lighting mechanisms 400 are symmetrically installed on the main LED lamp assembly 200.

[0064] In this embodiment, the adjustable illumination range LED floodlight is fixedly installed on the whole device through the lamp body fixing base 100;

[0065] The main LED lamp assembly 200 serves as the core lighting component, providing basic illumination.

[0066] The rotary adjustment structure 300 is connected to the main LED lamp assembly 200. By driving the main LED lamp assembly 200 to flip up or down, the illumination angle of the main lamp body can be adjusted.

[0070] Example 2

[0071] like Figures 1-10 As shown, improvements are made based on Example 1:

[0072] Furthermore, the lamp body fixing base 100 includes an I-shaped fixing base plate 110, and both ends of the I-shaped fixing base plate 110 are integrally formed with support arms 120.

[0073] The four corners of the I-shaped fixed base plate 110 are provided with countersunk holes 150;

[0074] The main LED light assembly 200 is installed between the two support arms 120.

[0075] In this embodiment, the lamp body fixing base 100 includes an I-shaped fixing base plate 110, and the integrally formed support arms 120 at both ends provide installation support for other components;

[0076] The countersunk holes 150 at the four corners of the I-shaped base plate 110 are used to fix the device to the mounting surface;

[0077] The main LED light assembly 200 is installed between the two support arms 120 to achieve the positioning and installation of the main light body.

[0078] In this embodiment, the I-shaped fixing base plate 110 takes into account both structural stability and lightweight, the countersunk hole 150 ensures that the installation is firm and aesthetically pleasing, and the I-shaped fixing base plate 110, together with the two support arms 120, provides a stable installation foundation for the main LED lamp assembly 200.

[0079] Furthermore, the lamp body fixing base 100 also includes mounting holes 130 opened on one end of the top of the two support arms 120, and bearings 140 are embedded in both mounting holes 130.

[0080] The main LED light assembly 200 includes a main light box 210, on which a main LED light board 220 is fixedly installed.

[0081] A rotating shaft 230 is fixedly installed on each of the opposite side walls of the main light box 210. Both rotating shafts 230 are inserted into the inner ring of the corresponding bearing 140, and the ends of both rotating shafts 230 extend outward.

[0082] A driven synchronous pulley 240 is fixedly installed on one end of the outer side of the rotating shaft 230 located on one side of the rotary adjustment structure 300.

[0083] One end of the rotary adjustment structure 300 is mounted on the driven synchronous pulley 240.

[0084] In this embodiment, the bearings 140 in the mounting holes 130 at the top of the two arms 120 of the lamp body fixing base 100 cooperate with the rotating shaft 230 on the side wall of the main lamp box 210 in the main LED lamp body assembly 200, so that the main lamp box 210 can rotate around the rotating shaft 230.

[0085] The main LED light panel 220 on the main light box 210 provides illumination, and the driven synchronous wheel 240 at the end of one of the rotating shafts 230 provides the driving force point for the rotary adjustment structure 300.

[0086] In this embodiment, the cooperation between the bearing 140 and the rotating shaft 230 reduces rotational friction, making the adjustment of the main lamp body angle smoother;

[0087] The driven synchronous pulley 240 is configured as a rotary adjustment structure 300, providing a reliable transmission interface to ensure adjustment accuracy.

[0088] Furthermore, the rotary adjustment structure 300 includes a micro stepper motor 310, which is fixedly mounted on the side wall of one of the support arms 120.

[0089] The axis of the output shaft of the micro stepper motor 310 is parallel to the axes of the two rotating shafts 230;

[0090] A driving synchronous pulley 320 is fixedly mounted on the output shaft of the micro stepper motor 310. A synchronous belt 330 is sleeved on the driving synchronous pulley 320. The end of the synchronous belt 330 away from the driving synchronous pulley 320 is sleeved on the driven synchronous pulley 240.

[0091] The driving synchronizing pulley 320 and the driven synchronizing pulley 240 are on the same vertical plane.

[0092] In this embodiment, after the micro stepper motor 310 fixed to the side wall of the support arm 120 is started, the output shaft drives the active synchronous wheel 320 to rotate. The active synchronous wheel 320 drives the driven synchronous wheel 240 to rotate through the synchronous belt 330, thereby driving the main LED lamp assembly 200 to rotate up and down around the rotating shaft 230.

[0093] The driving synchronizing pulley 320 and the driven synchronizing pulley 240 are in the same vertical plane to ensure transmission stability.

[0094] In this embodiment, the micro stepper motor 310 provides precise driving force, and the meshing transmission between the synchronous belt 330 and the synchronous pulley ensures accurate and reliable angle adjustment. There is no need to manually loosen / tighten the bolts, making operation convenient and avoiding the problem of lamp body sagging caused by loose bolts.

[0095] In this embodiment, it should be noted that the micro stepper motor 310 is a stepper motor with model number OT-GSM35-368, or a stepper motor with model number OT-GSM24-489, or a stepper motor with model number OT-GSM35-005, or a stepper motor with model number OT-GSM20-569, manufactured by Wanzhida Motor Manufacturing Co., Ltd.

[0096] More specifically, both the driving synchronizing pulley 320 and the driven synchronizing pulley 240 have several tooth grooves on their side walls (not shown in the figure), and both the inner side walls of the synchronizing belt 330 have several teeth (not shown in the figure). The teeth on the inner side walls of the synchronizing belt 330 can mesh and match with the tooth grooves on the driving synchronizing pulley 320 and the driven synchronizing pulley 240.

[0097] In this embodiment, the tooth grooves on the sidewalls of the active synchronizing pulley 320 and the driven synchronizing pulley 240 mesh with the teeth on the inner sidewall of the synchronizing belt 330 to ensure that power is transmitted from the active synchronizing pulley 320 to the driven synchronizing pulley 240 without slippage through the synchronizing belt 330.

[0098] In this embodiment, the meshing structure of the tooth groove and teeth eliminates transmission slippage, improves power transmission efficiency and adjustment accuracy, and ensures stable and reliable adjustment of the main lamp body angle.

[0099] Furthermore, the bottom of the main light box 210 has beveled portions 250 at both opposite ends.

[0100] In this embodiment, the oblique cut portions 250 at opposite ends of the bottom of the main lamp box 210 avoid collision and interference with the lamp body fixing base 100 or other components during the up-and-down flipping process of the main lamp body.

[0101] In this embodiment, the main lamp body is allowed to be freely adjusted within a large angle range, improving the adjustment flexibility of the device and avoiding damage caused by component interference.

[0102] Furthermore, both adjustable auxiliary lighting mechanisms 400 include two auxiliary LED lamp assemblies 410, which are respectively located on the upper and lower sides of the main light box 210.

[0103] A telescopic adjustment structure 420 is installed between the two sets of auxiliary LED light assemblies 410 and the main light box 210;

[0104] Each of the two sets of auxiliary LED light assemblies 410 is movably mounted with a frame structure 430, and the two sets of frame structures 430 are respectively installed on the upper and lower parts of the main light box 210.

[0105] The two sets of telescopic adjustment structures 420 can drive the corresponding secondary LED light assembly 410 when they extend or retract, and make it flip up or down.

[0106] In this embodiment, the auxiliary LED lamp body assemblies 410 of the two adjustable auxiliary lighting mechanisms 400 are located on the upper and lower sides of the main lamp box 210, respectively, and are connected to the main lamp box 210 through the telescopic adjustment structure 420.

[0107] The frame structure 430 movably mounts the secondary LED lamp assembly 410 onto the main lamp box 210;

[0108] When the telescopic adjustment structure 420 is extended or retracted, it drives the auxiliary LED lamp assembly 410 to flip up and down, adjusting the illumination angle of the auxiliary lamp.

[0109] In this embodiment, the overall illumination range of the floodlight is further expanded by independently adjusting the secondary LED lamp assembly 410, meeting the lighting needs of different scenarios and improving the practicality of the device.

[0110] Furthermore, both sets of secondary LED light assemblies 410 include secondary light boxes 4101, and secondary LED light boards 4102 are fixedly installed on both secondary light boxes 4101. Bearings 4103 are fixedly installed at both ends of the bottom of the two secondary LED light boards 4102.

[0111] Both sets of frame structures 430 include U-shaped brackets 4301, and the bases of the two U-shaped brackets 4301 are respectively fixedly installed on the upper and lower parts of the main light box 210;

[0113] Both bearing seats 4103 are sleeved and installed at both ends of the shaft 4302, and after being sleeved, they are rotatably connected to the shaft 4302;

[0114] One end of each of the two sets of telescopic adjustment structures 420 is connected to the bottom of the auxiliary lamp box 4101, and the other end is connected to the upper and lower parts of the main lamp box 210, respectively.

[0115] In this embodiment, the secondary LED light panel 4102 on the secondary light box 4101 of the secondary LED light body assembly 410 provides auxiliary lighting; the bearing 4103 at the bottom of the secondary light box 4101 is sleeved on both ends of the shaft 4302 of the U-shaped bracket 4301 in the frame structure 430, so as to realize the secondary light body rotating around the shaft 4302.

[0116] The telescopic adjustment structure 420 connects the auxiliary lamp box 4101 and the main lamp box 210, driving the auxiliary lamp body to flip.

[0117] In this embodiment, the cooperation between the bearing seat 4103 and the shaft 4302 ensures smooth rotation of the auxiliary lamp body, and the U-shaped bracket 4301 provides stable support, making the angle adjustment of the auxiliary lamp body reliable and expanding the lighting range.

[0118] Furthermore, both sets of telescopic adjustment structures 420 include electric telescopic rods 4201. Lower U-shaped connecting seats 4202 are movably mounted on the connecting seats at the bottom of the cylinders of the two electric telescopic rods 4201 via pins. Upper U-shaped connecting seats 4203 are movably mounted on the piston rod ends of the two electric telescopic rods 4201 via pins. The two lower U-shaped connecting seats 4202 are respectively fixedly installed at the center of the upper and lower parts of the main lamp box 210, and the two upper U-shaped connecting seats 4203 are respectively fixedly installed at the center of the side wall of the corresponding auxiliary lamp box 4101.

[0120] When the electric telescopic pole 4201 extends or retracts, the lower U-shaped connecting seat 4202 and the upper U-shaped connecting seat 4203, connected by a pin, adapt to the angle change and drive the auxiliary lamp box 4101 to rotate around the shaft 4302.

[0121] In this embodiment, the electric telescopic rod 4201 provides precise telescopic driving force, and the cooperation between the U-shaped connecting seat and the pin ensures flexible transmission, realizing convenient and precise adjustment of the auxiliary lamp body angle, further improving the ease of operation of the device and the expansion of the lighting range.
