Description
Technical Field
[0001] This utility model relates to the field of semiconductor light-emitting technology, and in particular to a semiconductor light-emitting device with a reinforced connection structure. Background Technology
[0002] Semiconductor light-emitting diode (LED) lamps are lighting devices that use semiconductor chips as light-emitting materials. These lamps consist of fixed protective components, wiring accessories, etc. They can transmit light, distribute and change the light distribution of the light source, and have a variety of light colors such as red, yellow, and blue. They are widely used in display screens, traffic signals, automotive lighting, and medical fields.
[0003] In string light products, the electrical connection and mechanical fixation of LED lights to circuit boards mostly rely on the insertion and extraction mechanism between the protruding edge of the LED light's bottom and the plastic slot of the circuit board. The core of this mechanism is only the interference fit between the protruding edge and the slot to form a preliminary fixation. Some products use adhesives to enhance the connection. However, string lights inevitably suffer from dynamic loads such as vibration and impact during use. In addition, the temperature cycle of the outdoor environment causes inconsistent deformation between the plastic slot and the LED protruding edge due to the difference in the coefficient of thermal expansion of the materials. This leads to a gradual increase in the fit gap, resulting in loose connection and poor contact. Therefore, we propose a semiconductor light-emitting device with a reinforced connection structure. Utility Model Content

This can solve the problem that in light string products, the electrical connection and mechanical fixation of LED lights and circuit boards mostly rely on the insertion and extraction of the protruding edge of the LED light bottom and the plastic slot of the circuit board. The core of this is only to form a preliminary fixation through the interference fit between the protruding edge and the slot. Some products are supplemented with adhesives to enhance the connection. However, during the use of light strings, they inevitably suffer from dynamic loads such as vibration and impact. In addition, the temperature change cycle of the outdoor environment causes the plastic slot and the LED protruding edge to deform inconsistently due to the difference in the thermal expansion coefficient of the materials.

[0028] LED string 1: As the basic carrier of the entire semiconductor light-emitting device, it is used to install multiple LED lamp heads 2 and add a fixing and positioning structure, provide circuit connection path, and realize the power transmission and overall series connection of multiple LED lamp heads 2;
[0029] LED lamp head 2: The core light-emitting component of the device, which obtains power from the lamp string 1 and realizes the light-emitting function. Its external convex ring 5 provides clamping points for the fixing and positioning structure, ensuring its installation stability on the lamp string 1.
[0030] Fixed frame 3: Fixedly connected to the top of the light string 1, it provides an installation base and motion guide for components such as rotating disk 4 and reinforcing limiting plate 7 with fixed positioning structure. The positioning groove 11 on its top and the sliding groove 10 on its outer surface respectively constrain the movement trajectory of positioning column 14 and sliding handle 6.
[0031] Rotating disk 4: Rotatably connected inside the fixed frame 3, located outside the LED lamp head 2, it drives the sliding block 15 to slide in the hexagonal groove 9 by its own rotation, thereby driving multiple reinforcing limiting plates 7 to move synchronously, realizing the clamping or loosening of the protruding ring 5 of the LED lamp head 2.
[0032] 5. The protruding ring is integrally formed on the outside of the LED lamp head 2. It serves as a clamping structure and works in conjunction with the reinforcing limiting plate 7 to ensure that the LED lamp head 2 is securely installed on the light string 1 through the reinforcing and fixing structure, preventing the LED lamp head 2 from loosening or falling off.
[0033] Sliding handle 6: It is fixedly connected to the outer surface of the rotating disk 4 and slidably connected inside the sliding groove 10. It provides the operator with a force point to rotate the rotating disk 4. By sliding inside the sliding groove 10, it drives the rotating disk 4 to rotate. The through hole 8 at the top is used to fix the position of the rotating disk 4 with the bolt 13.
[0034] The reinforcing limiting plate 7 is arranged in a circular array on the top of the rotating disk 4 and contacts the inner top wall of the fixing frame 3. The bottom is connected to the hexagonal groove 9 of the rotating disk 4 through the sliding block 15. The positioning post 14 at the top slides in the positioning groove 11 and moves radially under the drive of the rotating disk 4. Together, they form a ring clamp on the convex ring 5 of the LED lamp head 2 to achieve reinforcement and limiting.
[0035] Through hole 8: It is opened at the top of the sliding handle 6 to accommodate the bottom end of the bolt 13. When the bolt 13 is screwed into the threaded hole 12, the bottom end passes through the through hole 8 to limit the sliding handle 6, thereby fixing the position of the rotating disk 4.
[0036] Hexagonal groove 9: It is formed on the top of the rotating disk 4 to provide a sliding track for the sliding block 15. Utilizing the structural characteristics of the hexagon, the rotating disk 4 drives multiple sliding blocks 15 to move synchronously in and outward along the radial direction when it rotates, thereby driving the reinforcing limiting plate 7 to work together.
[0037] Sliding groove 10: It is formed on the outer surface of the fixed frame 3 to provide sliding space and rotation guidance for the sliding handle 6, limit the range of motion of the sliding handle 6, and ensure the stability of the rotating disk 4 when it rotates.
[0038] Positioning groove 11: It is formed on the top of the fixed frame 3 and slides with the positioning post 14 on the top of the reinforcing limiting plate 7 to constrain the movement direction of the reinforcing limiting plate 7, prevent it from shifting or tilting during movement, and ensure the consistency of the movement of multiple reinforcing limiting plates 7.
[0039] Threaded hole 12: It is opened on the top of the fixed frame 3 and communicates with the sliding groove 10. It is used to connect with the bolt 13 by threading. The sliding handle 6 is fixed by screwing in the bolt 13, thereby locking the position of the rotating disk 4 and the reinforcing limit plate 7.
[0040] Bolt 13: The threaded connection is inside the corresponding threaded hole 12, and the bottom end is located in the through hole 8. By tightening, the bottom end presses against the sliding handle 6, fixing the rotating disk 4 in the current position to prevent it from rotating unexpectedly due to vibration or other factors during the use of the device, thus ensuring the stability of the reinforcement effect.
[0041] Positioning post 14: It is fixedly connected to the top of the reinforcing limiting plate 7 and slidably connected inside the corresponding positioning groove 11. It cooperates with the positioning groove 11 to provide guidance for the movement of the reinforcing limiting plate 7, ensuring that it always moves smoothly in the radial direction and avoiding the reinforcing limiting plate 7 from deflecting and affecting the clamping effect.
[0042] Sliding block 15: It is fixedly connected to the bottom of the reinforcing limiting plate 7 and slidably connected inside the hexagonal groove 9. As a connecting component between the rotating disk 4 and the reinforcing limiting plate 7, it converts the rotational motion of the rotating disk 4 into the radial linear motion of the reinforcing limiting plate 7, thereby realizing the power transmission between the two.
[0043] Example 1:
[0044] like Figure 1-4 As shown, the light string 1 is made of flexible circuit board material, and multiple LED lamp heads 2 are evenly installed on its top. Each LED lamp head 2 has a convex ring 5 integrally formed on its outside. The convex ring 5 is made of transparent material. The top of the light string 1 is provided with a fixing structure, which is located on the outside of the LED lamp heads 2 on the light string 1.
[0045] Fixing bracket 3: The fixing bracket 3 is made of circular plastic and is fixedly connected to the top of the light string 1 by hot melt adhesive. Multiple positioning grooves 11 are evenly opened on the top of the fixing bracket 3.
[0046] Rotating disk 4: The rotating disk 4 is made of circular plastic and is rotatably connected inside the fixed frame 3. A hexagonal groove 9 is provided on its top, with a side length of 5mm. The rotating disk 4 is located outside the corresponding LED lamp head 2 and does not contact the LED lamp head 2.
[0047] Reinforcing limiting plate 7: Multiple reinforcing limiting plates 7 are arranged in a circular array on the top of the rotating disk 4, and are in contact with the inner top wall of the fixed frame 3. A positioning column 14 is fixedly connected to the top of the plate. The positioning column 14 is cylindrical and is slidably connected inside the corresponding positioning groove 11.
[0048] Sliding block 15: Multiple sliding blocks 15 are slidably connected inside the hexagonal groove 9 and are fixedly connected to the bottom of the corresponding reinforcing limiting plate 7. The sliding block 15 is cuboid in shape and cooperates with the hexagonal groove 9 to realize the sliding of the reinforcing limiting plate 7.
[0049] Sliding handle 6 and bolt 13: The sliding handle 6 is made of rectangular plastic and is fixedly connected to the outer surface of the rotating disk 4. A sliding groove 10 is provided on the outer surface of the fixing bracket 3. The sliding handle 6 is slidably connected to the inside of the sliding groove 10. A through hole 8 is provided at the top of the sliding handle 6. Two threaded holes 12 are provided at the top of the fixing bracket 3. Both threaded holes 12 are connected to the inside of the sliding groove 10. The bolt 13 is made of metal and is threadedly connected to the inside of the corresponding threaded hole 12. The bottom end of the bolt 13 is located inside the through hole 8 and is used to fix the position of the rotating disk 4.
[0050] When it is necessary to adjust the position of the reinforcing limiting plate 7, loosen the bolt 13 so that its bottom end is disengaged from the through hole 8, and then slide it in the sliding groove 10 through the sliding handle 6, driving the rotating disk 4 to rotate. The rotation of the rotating disk 4 drives multiple reinforcing limiting plates 7 to move through the hexagonal groove 9 and the sliding block 15, so that multiple reinforcing limiting plates 7 slide to the top of the convex ring 5 and contact the outer surface of the LED lamp head 2. Then, tighten the bolt 13 so that its bottom end enters the through hole 8, fixing the position of the rotating disk 4, thereby achieving the reinforcement and positioning of the LED lamp head 2.
[0051] Example 2:
[0052] This embodiment represents the basic form of the device and is suitable for reinforcing LED lamp heads with a conventional diameter of 10-15mm.
[0053] There are 6 reinforcing limiting plates 7 arranged in a circular array. The inner arc radius of each limiting plate is 8mm, which matches the diameter of the convex ring 5 of the LED lamp head 2, which is 16mm. When closed, they form a complete ring that hugs and holds the convex ring 5.
[0054] The side length of the hexagonal groove 9 is adapted to the sliding block 15, which is made of wear-resistant nylon material to ensure that the rotating disk 4 rotates without jamming.
[0055] The positioning groove 11 is elongated and 15mm long, guiding the positioning post 14 to slide and limiting the radial movement of the reinforcing limiting plate 7 by a maximum of 5mm.
[0056] Insert the LED lamp head 2 into the mounting position of the light string 1, ensuring that the convex ring 5 is located inside the cavity of the fixing frame 3;
[0057] Push the sliding handle 6 to rotate clockwise along the sliding groove 10, and the 6 reinforcing limiting plates 7 will simultaneously retract inward until they fit the convex ring 5.
[0058] Screw the bolt 13 through the through hole 8 into the inner threaded hole 12 to lock the rotating disk 4 and complete the reinforcement.
[0059] Example 3:
[0060] This embodiment is applicable to multi-head integrated light strings, such as Christmas light strings, to achieve synchronous reinforcement of multiple LED head 2.
[0061] The fixing frame 3 adopts an integrated long strip structure, covering 5-10 LED lamp heads 2 at the top of the light string 1. Each lamp head corresponds to a set of independent rotating disks 4 and reinforcing limiting plates 7.
[0062] Each rotating disk 4 is connected by a linkage rod, enabling simultaneous control of the rotation of multiple rotating disks 4 in a single operation, which greatly improves the efficiency of batch reinforcement.
[0063] The sliding groove 10 is designed as a continuous long arc, and the sliding handle 6 can slide along the groove to any lamp head position to complete the independent reinforcement of one or more lamp heads.
[0064] Efficiency Improvement: Compared to a single operation, the time required for simultaneous reinforcement of 5 lamp heads has been reduced from 25 seconds to 8 seconds, resulting in a 68% increase in efficiency.
[0065] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
