Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED light with adjustable lighting range. Background Technology

[0002] LED, or light-emitting diode, has a basic structure consisting of an electroluminescent semiconductor chip that is fixed to a support using silver or white glue. The chip and circuit board are then connected by silver or gold wires, and the entire circuit is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. As a result, LED lights have good shock resistance and are widely used in mobile phones, desk lamps, home appliances, and machinery manufacturing.

[0003] For example, Chinese Patent Publication No. CN214948301U discloses an LED lamp with adjustable lighting range, including a lamp post, a mounting base at the upper end of the lamp post, a lamp cover at the lower end of the lamp post, a lamp holder at the center inside the lamp cover, an LED lamp at the lower end of the lamp holder, a vertical rod at the upper end of the lamp holder, a movable block at the upper end of the vertical rod, sliders at both ends of the movable block, grooves on both sides of the inner wall of the lamp post, a screw hole through the center of the movable block, and wire holes on both sides of the screw hole. This LED lamp with adjustable lighting range can adjust the vertical height of the LED lamp by setting up a screw, movable block, slider, vertical rod and protective cover.

[0004] However, in the above solution, the device can only adjust the angle of one LED light when in use, which is not convenient for adjusting the angle of two LED lights at the same time. This limits the lighting range of the LED lights and makes them less applicable. Utility Model Content

A motor is fixedly connected to the side wall of the mounting cavity, and the output shaft of the motor is fixedly connected to one end of the side wall of one of the winding rods. A transmission wheel is fixedly connected to the outer side wall of both winding rods, and the two transmission wheels are connected by a transmission belt. Two pull ropes are wound around the outer side wall of both winding rods. One end of each of the four pull ropes passes through the side wall of the lamp holder and is movably connected to the lamp holder. The bottom of each of the four pull ropes is fixedly connected to the top side wall of the outer casing.

[0009] As a further improvement to this technical solution: all four pull ropes are made of steel wire rope.

[0010] As a further improvement to this technical solution: a circular card holder is fixedly connected to the bottom of the lamp holder, and a conical groove is opened at the bottom of the circular card holder. A conical card head is fixedly connected to the top of the outer shell, and the top of the conical card head is adapted to the conical groove at the bottom of the circular card holder.

[0011] As a further improvement to this technical solution: the surface of the rotating block is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the device can adjust the angle of two LED lights simultaneously through the cooperation of components such as the winding rod, transmission wheel, fixing rod, and worm gear, so that the two LED lights can rotate in two directions at the same time, thereby improving the lighting range of the LED lights, improving the applicability of the device, and making it simple, convenient and quick to operate.

[0023] Please see Figure 1-3 In this embodiment of the present invention, an adjustable LED lamp includes a lamp holder 1. Two fixing plates 18 are fixedly connected to both sides of the lamp holder 1. Fixing holes 17 are provided on the side walls of the four fixing plates 18. An installation cavity 2 is provided inside the lamp holder 1. A housing 16 is connected to the installation cavity 2 through a lifting structure. A rotating rod 15 is rotatably connected to the side wall of the housing 16. Two worm gears 19 are fixedly connected to the side wall of the rotating rod 15. The two worm gears 19 are arranged in opposite directions. One end of the rotating rod 15 passes through the side wall of the housing 16 and is fixedly connected to a rotating block 10. The surface of the rotating block 10 is provided with anti-slip texture. The outer ring side wall of the rotating rod 15 is rotatably connected to the housing 16 through a rubber ring pad. Two fixing rods 14 are rotatably connected to the inner side wall of the housing 16. A turbine 11 is fixedly connected to the outer ring side wall of the two fixing rods 14. The two turbines 11 are respectively meshed with the two worm gears 19. A connecting rod 13 is fixedly connected to the bottom of the two turbines 11. The bottom of the two connecting rods 13 extends out of the housing 16 and is fixedly connected to the LED lamp body 12.

[0024] Please see Figure 1-3The lifting structure includes two winding rods 3, both of which are rotatably connected within the mounting cavity 2. A motor 7 is fixedly connected to the side wall of the mounting cavity 2, and the output shaft of the motor 7 is fixedly connected to one end of the side wall of one of the winding rods 3. A transmission wheel 5 is fixedly connected to the outer side wall of each of the two winding rods 3, and the two transmission wheels 5 are connected by a transmission belt 4. Two pull ropes 6 are wound around the outer side wall of each of the two winding rods 3, and one end of each of the four pull ropes 6 passes through the side wall of the lamp holder 1 and is movably connected to the lamp holder 1. The bottom of each of the four pull ropes 6 is fixedly connected to the top side wall of the outer casing 16. All four pull ropes 6 are made of steel wire rope. When the motor 7 is started, the output shaft of the motor 7 drives the winding rod 3 to rotate. The winding rod 3 drives the other winding rod 3 to rotate simultaneously through the two transmission wheels 5 and the transmission belt 4. When the two winding rods 3 rotate, they can wind up or lower the four transmission wheels 5, thereby facilitating the adjustment of the height of the two LED lamp bodies 12, which makes it easy to maintain and replace the LED lamp bodies 12.

[0025] Please see Figure 1-3 A circular bracket 8 is fixedly connected to the bottom of the lamp holder 1. A conical groove is provided at the bottom of the circular bracket 8. A conical clip 9 is fixedly connected to the top of the outer shell 16. The top of the conical clip 9 is adapted to the conical groove at the bottom of the circular bracket 8. Through the circular bracket 8 and the conical clip 9, the conical clip 9 can be moved when the outer shell 16 moves upward, so that the top of the conical clip 9 enters the conical groove at the bottom of the circular bracket 8, thereby improving the stability between the lamp holder 1 and the outer shell 16.

[0026] The working principle of this utility model is as follows: The four fixing holes 17 facilitate the installation of the device. Starting the motor 7 causes the output shaft of the motor 7 to rotate the winding rod 3. The winding rod 3, through two transmission wheels 5 and a transmission belt 4, simultaneously rotates another winding rod 3. When the two winding rods 3 rotate, they can wind up or lower the four transmission wheels 5, thus facilitating the adjustment of the height of the two LED lamp bodies 12, making maintenance and replacement of the LED lamp bodies 12 easier. Rotating the rotating block 10 causes the rotating rod 15 to drive the two worm gears 19 to rotate. Since the two worm gears 19 are arranged in opposite directions, their rotation drives the two turbines 11 to rotate in opposite directions. The two turbines 11 drive the two LED lamp bodies 12 to rotate, causing them to rotate simultaneously to both sides, thereby adjusting the angle of the two LED lamp bodies 12 and thus adjusting their illumination range. The rubber gasket between the rotating rod 15 and the outer casing 16 allows the rotating rod 15 to rotate under external force, preventing it from rotating on its own.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
