Description

Technical Field

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

[0002] LED logo lights are lighting devices that utilize LED technology. They are commonly used in commercial and residential environments to enhance brand image and improve the visual appeal of a space. LED logo lights use LEDs as the light source, which features high brightness, low energy consumption, and long lifespan. LED lights convert electrical energy directly into light energy through electroluminescence, making them highly efficient and environmentally friendly.

[0003] LED logo lights are widely used in shop windows, company reception areas, exhibitions, hotel lobbies, and other places. They not only illuminate the space but also attract attention and enhance brand image through unique designs. For example, the existing technology, Chinese Patent Publication No. "CN222363151U", provides a new type of fan blade LOGO display LED light fan, including a fan frame, a back plate fixedly installed on the back of the fan frame, a metal bushing fixedly installed inside the fan frame, a bottom cover movably sleeved inside the metal bushing, a bearing inner ring fixedly sleeved on the outer surface of the metal bushing, and a ball bearing movably installed on the outer surface of the bearing inner ring. This invention, by setting up a metal bushing, a bottom cover, a fan blade bushing, and an impeller, allows the impeller and fan blade bushing to rotate, which in turn causes the outer ring of the bearing to rotate, thereby causing the balls to roll. At the same time, the inner ring of the bearing remains stationary, which in turn keeps the metal bushing stationary, and thus the bottom cover remains stationary. This allows the bottom cover to remain stationary while the impeller rotates, and the logo on the outer surface of the bottom cover can still be clearly seen when the impeller is rotating, improving the overall aesthetics of the device.

[0004] Currently, LED logo lights are typically designed with a fixed angle, meaning the direction and range of the light are pre-set. This fixed design can be inflexible in situations requiring flexible light adjustment. In scenarios demanding dynamic changes or adjustments, such as exhibitions, stage performances, or interior decoration, the inability to adjust the angle of LED logo lights can limit designers' creative expression. For example, at exhibitions, the position of exhibits may need to be adjusted as needed; if the lighting cannot be adjusted accordingly, it could negatively impact the display effect. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an LED logo light with an adjustable projection angle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an adjustable projection angle LED logo light, including a base, a support frame fixedly installed on the top of the base, the support frame having a U-shaped structure, bushings fixedly through both sides of the support frame, the same shaft being rotatably arranged through the bushings distributed on both sides, a brake motor being provided at the outer end of the shaft, a drive shaft being provided inside the brake motor, and the end of the drive shaft being connected to the shaft via a coupling, the surface of the shaft being fixedly fitted with a sleeve;

[0008] Connecting rods are fixed on both sides of the outer wall of the sleeve. An LED light is fixedly installed at the end of the connecting rod away from the sleeve. A terminal is provided at the tail of the LED light. The illuminating end of the LED light is covered with a LOGO light-transmitting template.

[0009] Preferably, the lower end of the base has fixed bearings distributed along both sides, and the inner ring wall of the bearings is fitted with a connecting shaft by interference fit.

[0010] Preferably, a connecting plate is assembled at the lower end of the connecting shaft, and a wheel is fixedly installed at the lower end of the connecting plate.

[0011] Preferably, a plurality of mounting plates 1 are fixedly distributed on the outer ring wall of the LED lamp housing, and a plurality of mounting plates 2 are fixedly distributed on the outer ring wall of the LOGO light-transmitting template, with the positions of mounting plates 2 corresponding to those of mounting plates 1.

[0012] Preferably, a threaded post is fixedly installed on the surface of the second mounting plate, and an inner sleeve is fixedly installed through the interior of the first mounting plate, with the threaded post and the inner sleeve being slidably sleeved together.

[0013] Preferably, a threaded cap is threaded onto the end of the threaded column, and one end of the threaded cap is tightly fitted against the end face of the inner sleeve.

[0014] Preferably, a cylinder is fixedly mounted on the side of the support frame away from the brake motor via a bracket. The cylinder has a piston rod for extension and retraction inside, and a pressing seat is fixedly mounted on the end of the piston rod. The inner arc surface of the pressing seat is in close contact with the surface of the shaft.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application:

[0016] 1. This solution uses a brake motor to drive the shaft and rotate the sleeve, so that the LED lights on both sides can be adjusted synchronously to adjust the illumination angle. This structure can not only flexibly adapt to the projection needs of different occasions, but also ensure the stability after the angle is fixed by the built-in braking function of the brake motor. With the help of an external forward and reverse switch, the tilt angle of the light can be easily controlled to meet diverse display requirements. The dual-lamp layout design supports the simultaneous projection of two different logo patterns, which significantly improves the multifunctionality and efficiency of the equipment.

[0017] 2. As described in 1, the sliding sleeve of the threaded column and the inner sleeve are fastened with a threaded cap, so that the light-transmitting template and the lamp body form a modular connection, which not only ensures the stability of the installation but also enables manual operation. The universal wheel set achieves omnidirectional movement through the cooperation of bearings and connecting shafts, which facilitates flexible positioning on site.

[0018] 3. As described in 2, the piston rod of the cylinder can drive the extrusion seat to press and squeeze the shaft, which can be used in conjunction with the braking after the power is cut off by the brake motor to ensure the stability of the shaft position after rotation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4An adjustable projection angle LED logo light includes a base 1, a support frame 11 fixedly mounted on the top of the base 1, the support frame 11 having a U-shaped structure, bushings 12 fixedly passing through both sides of the support frame 11, a common shaft 13 passing through and rotatably mounted inside the bushings 12 distributed along both sides, a brake motor 15 mounted on the outer end of the shaft 13, a drive shaft mounted inside the brake motor 15, and the end of the shaft connected to the shaft 13 via a coupling, a sleeve 14 fixedly fitted on the surface of the shaft 13, the shaft 13 being able to rotate based on the bushings 12, allowing the sleeve 14 to be connected, thereby driving the LED light 17 to adjust the illumination angle; after the brake motor 15 is powered on, it can drive the shaft 13 through its shaft to move in tandem; the brake motor 15 can be connected to a forward / reverse switch via wires, the forward / reverse switch being model HY2-8, to adjust the forward and reverse rotation of the brake motor 15;

[0026] Connecting rods 16 are fixed on both sides of the outer wall of sleeve 14. An LED light 17 is fixedly installed at the end of the connecting rod 16 away from sleeve 14. A terminal 18 is provided at the tail of the LED light 17. The illuminating end of the LED light 17 is covered with a LOGO light-transmitting template 19. The LED lights 17 are distributed along both sides of sleeve 14. Two LOGO lights can be set at the same time, which can facilitate the display of different LOGO icons at one time. The LOGO light-transmitting template 19 is a non-standard part and can be reasonably designed according to the LOGO icon to be transmitted. It is only necessary to ensure that the LOGO logo is illuminated by the LED light 17 and can be displayed through the LOGO light-transmitting template 19.

[0027] Among them, the lower end of the base 1 has fixed bearings 101 distributed along both sides. The inner ring wall of the bearing 101 is fitted with a connecting shaft 102. The connecting shaft 102 can rotate based on the bearing 101, thereby realizing the omnidirectional rotation of the wheel 104.

[0028] The lower end of the connecting shaft 102 is equipped with a connecting plate 103, and the lower end of the connecting plate 103 is fixedly installed with a wheel 104. The wheel 104 facilitates the displacement adjustment of the overall structure and allows for flexible movement on site.

[0029] Among them, several mounting plates 1-2 are fixedly distributed on the outer ring wall of the housing of LED lamp 17, and several mounting plates 21 are fixedly distributed on the outer ring wall of LOGO light-transmitting template 19. The positions of mounting plates 21 and mounting plates 2-2 correspond to those of mounting plates 1-2. Mounting plates 1-2 and mounting plates 21 can support the mounting components of LED lamp 17 and LOGO light-transmitting template 19.

[0030] Among them, a threaded post 22 is fixedly installed on the surface of the second mounting plate 21, and an inner sleeve 23 is fixedly installed through the inside of the first mounting plate 2. The threaded post 22 and the inner sleeve 23 are slidably connected. By connecting the threaded post 22 and the inner sleeve 23, the LED light 17 and the LOGO light-transmitting template 19 can be quickly positioned and connected.

[0031] The threaded post 22 is threaded with a threaded cap 24 at its end. One end of the threaded cap 24 is tightly fitted to the end face of the inner sleeve 23. The threaded cap 24 and the threaded post 22 are threaded together, which can achieve the fastening of the LED light 17 and the LOGO light-transmitting template 19.

[0032] Among them, a cylinder 3 is fixedly installed on the side of the support frame 11 away from the brake motor 15 by a bracket. The cylinder 3 is equipped with a piston rod for extension and retraction, and a pressing seat 31 is fixedly installed at the end of the piston rod. The inner arc surface of the pressing seat 31 is in close contact with the surface of the shaft 13. After the shaft 13 rotates a certain angle, the brake motor 15 is de-energized, which can form a braking effect, thereby ensuring that the shaft 13 will not rotate at will. Through the extension of the piston rod of the cylinder 3, the pressing seat 31 can press the surface of the shaft 13 to perform auxiliary anti-movement fastening, and also effectively protect the brake motor 15.

[0033] Working method: The brake motor 15 drives the shaft 13 to rotate, realizing the multi-angle projection adjustment of the LED light 17. The rotating shaft of the brake motor 15 is rigidly connected to the shaft 13 through a coupling. When the motor is powered on, the rotating shaft drives the shaft 13 to rotate inside the bushing 12. The bushing 12 is fixed to both sides of the U-shaped support frame 11 to provide stable support for the shaft 13. The sleeve 14 on the surface of the shaft 13 is fixedly connected to the connecting rods 16 on both sides. The LED light 17 at the end of the connecting rod 16 deflects synchronously, thereby adjusting the illumination direction of the LOGO light-transmitting template 19. The brake motor 15 has a built-in braking function. When the power is cut off, the rotating shaft can be locked immediately to prevent the shaft 13 from shifting due to external force or inertia. In addition, the cylinder 3 contacts the surface of the shaft 13 through the extrusion seat 31 at the end of the piston rod. When the cylinder 3 is started, the extrusion seat 31 applies radial pressure to further enhance the braking effect and ensure that the LED light 17 remains stable at the set angle.

[0034] The LED light 17 and the LOGO light-transmitting template 19 facilitate the replacement of templates with different patterns. The mounting plate 2 on the outside of the LED light 17 housing and the mounting plate 21 on the edge of the light-transmitting template 19 are precisely connected through the threaded post 22 and the inner sleeve 23. During installation, the threaded post 22 is inserted into the inner sleeve 23 and slid to complete the initial positioning; then the threaded cap 24 is tightened so that its end face presses tightly against the inner sleeve 23 to form a rigid fixation. This structure not only simplifies the template replacement process, but also ensures the sealing and alignment of the template and the LED light 17 through multi-point distribution. As a non-standard part, the LOGO light-transmitting template 19 can be customized according to the requirements. As long as its light transmittance matches the beam of the LED light 17, a clear logo can be projected.

[0035] The bottom of the base 1 is press-fitted with the connecting shaft 102 via the bearing 101, enabling the wheel 104 to rotate in all directions. The upper end of the connecting shaft 102 is fixed to the base 1, and the lower end is connected to the wheel 104 via the connecting plate 103. The inner ring of the bearing 101 is tightly fitted with the connecting shaft 102, and the outer ring is fixed to the base 1, allowing the wheel 104 to turn freely in 360°.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
