Description

Technical Field

[0001] The present invention relates to the technical field of lamp accessories, and particularly to a fixing structure for a lamp bead substrate. Background Art

[0002] The lamp bead substrate is an important component for fixing and connecting lamp beads and plays a key role in the lighting field. Early lamp bead substrates were relatively simple, mainly traditional printed circuit boards (PCBs), with single-sided or double-sided board structures, and the materials were usually ordinary copper-clad laminates. The technology at that time was mainly to achieve the electrical connection and mechanical fixation of lamp beads to meet basic lighting needs. In recent years, with the rapid development of LED technology, especially the increasing demand for high-power and high-density LED lighting, the lamp bead substrate technology has been continuously innovated.

[0003] The patent with the publication number CN222186773U discloses a fixing structure for a lamp bead substrate, including a lamp board. The bottom surface of the outer wall of the lamp board is fixedly connected with a fixing seat, and fixing chutes are opened on both sides of the inner wall of the fixing seat. The fixing chutes are located on both sides of the outer wall of the lamp board, and one side of the inner wall of the fixing chute is slidably connected with one side of the outer wall of the lamp board. One side of the outer wall of the lamp board is fixedly connected with a fixing block. A fixing groove is opened on one side of the inner part of the fixing seat, and the top end of the inner wall of the fixing groove is slidably connected with the bottom of the outer wall of the fixing block. One side of the outer wall of the fixing seat is fixedly connected with a connecting piece, and a plug pin is fixedly connected with the outer wall of the fixing seat on the side far from the connecting piece. One side of the outer wall of the plug pin is slidably connected with the center of the inside of the connecting piece. The device can realize the rapid installation and disassembly of the lamp board through the mutual cooperation between the adjusting button and the fixing block.

[0004] In the above technical solution, only the fixed clamping of the lamp beads can be realized. With the progress of the times, in some special lighting applications, certain requirements are also imposed on the optical performance of the lamp bead substrate, such as optimizing the light distribution, guiding the light to a specific direction, reducing glare or improving the lighting uniformity.

[0071] The upper surface of the lamp board 301 slopes downward from the middle hole 302 to the edge;

[0072] The surface of the lamp board 301 is evenly embedded with convex cylinder components. The convex cylinder component includes a cover cylinder 303. The cover cylinder 303 is penetrated and inserted on the lamp board 301. The upper end of the cover cylinder 303 protrudes and is flush with the upper surface of the lamp board 301. An air groove 304 is penetrated and opened in the upper end of one side of the cover cylinder 303 facing the middle hole 302. Clamping grooves 305 penetrated and opened on the cover cylinder 303 are respectively arranged on both circumferential sides of the air groove 304;

[0073] The upper end edge of the cover cylinder 303 is evenly provided with connecting pieces 306 embedded on the upper surface of the lamp board 301 at equal distances.

[0074] A lamp bead component 307 is arranged on the convex cylinder component and fits the upper end surface of the cover cylinder 303. The bottom buckle of the lamp bead component 307 is correspondingly snapped into the clamping groove 305, and the side pins of the lamp bead component 307 are correspondingly connected to the connecting pieces 306.

[0075] Please refer to Figure 13 , a first inner groove 403 is penetrated and opened in the middle of each gripping foot 402. The bottom end of the first inner groove 403 is bent and the bottom port is located inside the gripping foot 402;

[0076] Second inner grooves 404 are penetrated and opened in the top shell 401 at equal distances and evenly. The top end of the second inner groove 404 is bent and the top port is located on the upper side of the top shell 401;

[0077] The bottom port of the second inner groove 404 corresponds to and docks with the top port of the first inner groove 403;

[0078] A flexible rod 405 is adaptively inserted into each second inner groove 404. The lower end of the flexible rod 405 is correspondingly inserted into the first inner groove 403. The upper end of the flexible rod 405 extends out of the second inner groove 404 and is commonly fixedly connected with a button 406 that is adaptively inserted into the middle hole 302. A second spring 407 that winds around the flexible rod 405 is fixedly connected between the button 406 and the top shell 401;

[0079] Rod grooves 411 for adaptively inserting the flexible rods 405 are evenly formed at equal intervals on the outer side of the inner ball 408.

[0080] The working principle of the present invention is as follows:

[0081] Base assemblies are respectively arranged on the four sides of the main block 102. A lamp board component 3 is separately arranged on each base assembly. The large-area lamp bead substrate is divided into small-area lamp bead substrates and is connected and limited. The lamp bead components 307 on each lamp board 301 are separately controlled, so that the large-area lamp beads can be dispersedly controlled. The lamp bead substrates in each small area can be used in coordination with each other, and the assembly combination of the lamp beads is more diverse, thereby simulating more lighting effects.

[0082] During the assembly process of the lamp board component 3 and the sliding seat component 2, it is necessary to press the button 406 in the middle hole 302, so that the lower end of the flexible rod 405 extends out of the lower port of the first inner groove 403 and is correspondingly inserted into the rod groove 411. Keeping pressing the button 406 can make the gripper feet 402 and the inner ball 408 relatively stationary. By twisting the lamp board component 3, the screw groove 410 and the screw post 209 are screwed together. When the pressing of the button 406 is released, the gripper feet 402 and the inner ball 408 are relatively movable, so that the lamp board component 3 can rotate in a spherical shape formed by the fitting of the inner ball 408 and the embedded ball 208, enabling the connection function and the use function of the ball hinge component 4 to be switched freely, improving the working convenience.

[0083] The lamp board component 3 and the ball hinge component 4 can be transported as independent accessories. During the transportation process, the inner ball 408 can be flipped in the gripper feet 402, so that the screw groove 410 faces the direction of the top shell 401 to protect it, avoiding the problem of damage to the screw groove 410 during transportation and improving the service life.

[0084] The upper surface of the lamp board 301 slopes downward from the middle hole 302 to the edge. The slope increases the surface area available for installing the lamp bead components 307 relative to the plane, and the spacing between the same number of lamp bead components 307 increases, helping with heat dissipation.

[0085] The bottom buckle of the lamp bead component 307 corresponds to the slot 305, which helps to improve the connection stability of the lamp bead component 307. The side pins of the lamp bead component 307 correspond to the connecting piece 306. The slope structure on the upper surface of the lamp board 301 can disperse the fixing pressure of the bottom buckle of the lamp bead component 307 and the side pins, avoid disconnection caused by single-point force, and improve the fixing stability of the lamp bead component 307.

[0086] When the lamp bead component 307 generates heat, the hot air flow moves along the slope of the lamp board 301 toward the middle hole 302, and is dispersed after contacting the protruding upper end of the cover tube 303, thereby forming tiny turbulence around the convex tube component, further increasing the area of ​​air flow, and the turbulence forms low air pressure on the upper surface of the lamp board 301, which can draw in fresh air through the bottom of the cover tube 303 and pour it into the upper surface of the lamp board 301 from the air groove 304, further improving the heat dissipation.

[0087] The slider assembly slides along the base assembly to bring the lamp panel components 3 closer to each other, and the height of the rubber strip 106 sleeved on the vertical rod 105 is adjusted to align the rubber strip 106 and the lamp panel component 3. The lamp panel components 3 on the four sides are spliced ​​into one, and the lamp panel components 3 are limited to each other to form a non-adjustable form for normal operation.

[0088] By sliding the slider assembly along the base assembly, the lamp panel component 3 can be moved to a position where it can deflect freely, and the height and angle of the rubber strip 106 sleeved on the vertical rod 105 can be adjusted so that the rubber strip 106 lifts the lamp panel 301 close to one side of the main block 102, allowing the lamp panel 301 to work at different angles, optimizing light distribution, directing light in a specific direction, reducing glare or improving lighting uniformity.

[0089] Adjust the height of the rubber strip 106 sleeved on the vertical rod 105 so that the rubber strip 106 fits the lower surface of the lamp panel 301, and start the strip 103 to drive the auxiliary adjustment component to rotate through the hole 104. When the rubber strip 106 rotates, the lamp panel 301 can be driven to rotate around the inner ball 408 as the axis through friction. When lamp beads 307 of different colors are used, a streaming light effect can be formed, thereby increasing the diversity of lighting and the scope of use.

[0090] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
