Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED lamp bead with a heat dissipation bracket. Background Technology

[0002] As a highly efficient and energy-saving light source, LED beads are increasingly widely used in the lighting field. However, their photoelectric conversion efficiency is not 100%. Most of the electrical energy that is not converted into light energy will be dissipated in the form of heat. If this heat cannot be dissipated in a timely and effective manner, it will cause the junction temperature of the LED beads to be too high, which will seriously affect their luminous efficiency, stability and lifespan.

[0003] To address the heat dissipation problem, existing technologies typically equip LED chips with heat sink brackets. These brackets are often made of metal materials with good thermal conductivity and increase the contact area with air by adding heat sinks or heat dissipation fins in order to accelerate heat dissipation. However, this design mainly relies on external passive heat dissipation. For compact LED chips, the heat generated inside is difficult to conduct to the outside quickly and cannot form effective internal air convection, which easily leads to heat accumulation in the core area, resulting in low overall heat dissipation efficiency.

[0004] In addition, the way the LED beads are fixed to the heat sink bracket also directly affects the heat conduction efficiency and the reliability of the structure. Some simple clips or adhesives are easy to install, but they are prone to poor contact or loosening and falling off under long-term thermal expansion and contraction and vibration, which affects the stability of the heat conduction path. While the connection method using screws and other fasteners is reliable, the installation process is relatively cumbersome and not conducive to rapid production and maintenance.

[0005] Therefore, this utility model proposes an LED bead with a heat dissipation bracket to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of low heat dissipation efficiency and insufficient reliability of fixing structure in existing LED lamp beads with heat dissipation brackets, this utility model aims to provide an LED lamp bead with heat dissipation brackets with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an LED lamp bead with a heat dissipation bracket, including: an insulating mounting base and a first fixing plate detachably mounted on the insulating mounting base. The LED lamp bead also includes a heat dissipation component disposed on the insulating mounting base and a fixing component for fixing the first fixing plate to the insulating mounting base.

[0008] The heat dissipation component includes multiple heat dissipation teeth fixedly connected to the outer wall of the insulating mounting base. The insulating mounting base also has a first heat dissipation hole and a second heat dissipation hole that are staggered with each other. Through the synergistic effect of the external heat dissipation teeth and the internal heat dissipation holes, a basic internal and external heat dissipation channel is constructed.

[0009] Furthermore, the fixing assembly includes a fixing block fixedly connected to the lower surface of the first fixing plate, a slot is provided inside the insulating mounting base, and a fixing hole is provided inside the insulating mounting base for the insertion of the limiting post. The fixing assembly also includes a spring housed in the receiving cavity and a fixing ball partially housed in the receiving cavity. One end of the spring abuts against the inner wall of the insulating mounting base, and the other end abuts against the fixing ball. Through the cooperation of the fixing ball and the slot, a quick and elastic locking between the first fixing plate and the insulating mounting base is achieved.

[0010] Preferably, in order to further enhance the internal air convection heat dissipation effect, the heat dissipation component also includes a hollow inner ring disposed inside the insulating mounting base. The hollow inner ring is fitted inside the insulating mounting base and, together with the first heat dissipation hole and the second heat dissipation hole, defines an enhanced airflow channel. In order to further increase the internal heat exchange area, the heat dissipation component also includes a plurality of heat dissipation fins fixedly connected inside the insulating mounting base. The heat dissipation fins are located inside the airflow channel and can carry away more heat when air flows through them.

[0011] Preferably, in order to increase the downward heat dissipation path, the LED bead with heat dissipation bracket also includes a support plate, the insulating mounting base is fixedly connected to the support plate, and the heat dissipation assembly also includes multiple heat dissipation grooves formed on the lower surface of the support plate. This structure allows heat to be conducted from the insulating mounting base to the larger support plate, and further dissipated through the heat dissipation grooves, forming a more complete three-dimensional heat dissipation system.

[0012] Preferably, in order to achieve a final secure lock and enhance guidance during installation, the fixing assembly further includes a limiting post fixedly connected to the lower surface of the first fixing plate, the fixing hole being used to adaptably accommodate the limiting post and the fixing block, the fixing assembly further includes a second fixing plate fixedly connected to the lower surface of the first fixing plate and a threaded rod, the threaded rod passing through the second fixing plate and the insulating mounting base in sequence, and being threadedly connected to the insulating mounting base, providing a stronger fixing force through threaded locking based on elastic locking.

[0013] Preferably, in order to simplify the electrical connection structure and improve integration, the LED bead with heat dissipation bracket also includes an electrode sheet, which is integrally formed by extending from the side wall of the insulating mounting base, eliminating the need for additional wiring terminals and making external circuit connection more convenient and reliable.

[0014] Preferably, in order to form a complete light-emitting unit, the LED bead with heat dissipation bracket also includes multiple bead bodies and lamp covers. The bead bodies are fixedly connected to the inner wall of the first fixing plate and serve as a light source. The lamp covers are installed on the first fixing plate and cover the bead bodies, which protect the bead bodies and can also converge or diffuse the light.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problems of simple heat dissipation structure and low heat dissipation efficiency of LED beads in the prior art by setting heat dissipation teeth on the outside of the insulating mounting base, internally staggered heat dissipation holes, hollow inner ring and heat dissipation fins to form an internal air flow channel, and cooperating with heat dissipation grooves on the support plate. It achieves the technical effect of constructing a multi-dimensional three-dimensional heat dissipation network with internal convection, external radiation and downward conduction, improving heat dissipation performance, reducing the working temperature of the LED beads and extending their service life.

[0017] 2. This utility model solves the problems of cumbersome installation or insufficient connection reliability and easy loosening in the existing LED bead fixing method by setting an elastic locking structure composed of a fixing block, a slot, a spring and a fixing ball, and using a threaded rod for final locking. It achieves the technical effect of combining quick installation and positioning with firm locking, which simplifies the installation operation and ensures the long-term stability and vibration resistance of the connection.

[0018] 3.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 4 This utility model provides an LED lamp bead with a heat dissipation bracket, which aims to solve the problems of low heat dissipation efficiency and insufficient reliability of fixing structure of LED lamp beads in the prior art.

[0027] like Figure 1 As shown, the basic frame of the LED lamp bead with heat dissipation bracket includes a support plate 1, an insulating mounting base 2 fixedly connected to the support plate 1, and a first fixing plate 4 detachably mounted on the insulating mounting base 2. Multiple lamp bead bodies 7 are fixedly connected to the inner wall of the first fixing plate 4, and a lamp cover 5 for covering the lamp bead bodies 7 is also installed on the first fixing plate 4. An electrode plate 3 is integrally extended from the side wall of the insulating mounting base 2 for electrical connection. On this basic frame, the LED lamp bead also innovatively sets up a heat dissipation component 6 and a fixing component 8 that work together.

[0028] To achieve efficient multi-dimensional heat dissipation, please refer to... Figure 2The heat dissipation component 6 constructs a three-dimensional heat dissipation network, which includes multiple heat dissipation teeth 601 fixedly connected to the outer wall of the insulating mounting base 2 to increase the external heat dissipation area. At the same time, the interior of the insulating mounting base 2 has first heat dissipation holes 602 and second heat dissipation holes 603 that are staggered to each other to form an internal air convection channel. In order to further enhance the internal heat dissipation effect, the heat dissipation component 6 also includes a hollow inner ring 606 disposed inside the insulating mounting base 2. The hollow inner ring 606 is fitted inside the insulating mounting base 2 and, together with the first heat dissipation holes 602 and second heat dissipation holes 603, defines an enhanced air flow channel. Several heat dissipation fins 604 are fixedly connected in the air flow channel. These heat dissipation fins 604 are located in the air flow channel, increasing the surface area for internal heat exchange. In addition, in order to conduct the heat dissipation path downward, the heat dissipation component 6 also includes multiple heat dissipation grooves 605 opened on the lower surface of the support plate 1, thereby forming a comprehensive heat dissipation system from the inside to the outside and from top to bottom.

[0029] To achieve both quick installation and secure locking, please refer to... Figure 3 and Figure 4 The fixing component 8 adopts a step-by-step fixing structure. First, in order to achieve initial guidance and anti-rotation, the fixing component 8 includes a limiting post 801 fixedly connected to the lower surface of the first fixing plate 4.

[0030] To achieve rapid and flexible positioning, the fixing assembly 8 also includes a fixing block 807 fixedly connected to the lower surface of the first fixing plate 4. The interior of the insulating mounting base 2 has a slot, and the interior of the insulating mounting base 2 has a fixing hole 804 that can accommodate the limiting post 801. The spring 805 and the fixing ball 806 are housed in the receiving cavity. One end of the spring 805 abuts against the inner wall of the insulating mounting base 2, and the other end abuts against the fixing ball 806. When the fixing block 807 is inserted into the fixing hole 804, the fixing ball 806 is engaged in the slot by the elastic force of the spring 805, completing the initial positioning. The fixing ball 806 and the spring 805 are both housed in the internal space formed by the first fixing plate 4 and the insulating mounting base 2.

[0031] To achieve a secure lock, the fixing assembly 8 also includes a second fixing plate 802 and a threaded rod 803 fixedly connected to the lower surface of the first fixing plate 4. The threaded rod 803 passes through the second fixing plate 802 and the insulating mounting base 2 in sequence and is threadedly connected to the internal thread of the insulating mounting base 2. By tightening the threaded rod 803, the first fixing plate 4 can be firmly pressed onto the insulating mounting base 2.

[0032] The working principle of this utility model of an LED lamp bead with a heat dissipation bracket is as follows:

[0033] In terms of heat dissipation, when the lamp bead body 7 generates heat during operation, the heat is first conducted to the first fixing plate 4, and then conducted to the insulating mounting base 2 through the contact surface between the first fixing plate 4 and the insulating mounting base 2. The heat dissipation process is carried out through three parallel paths. The heat is conducted inward through the internal structure of the insulating mounting base 2, heating the air in the airflow channel defined by the hollow inner ring 606 and the heat dissipation fins 604. The hot air rises due to the decrease in density and is discharged through the first heat dissipation hole 602 at the top. At the same time, the external cold air is drawn in from the second heat dissipation hole 603 at the bottom, forming a continuous internal natural convection. The heat dissipation fins 604 greatly improve the heat exchange efficiency in this process. The heat is conducted to the outer wall of the insulating mounting base 2, and the heat is directly dissipated to the surrounding environment through the heat dissipation teeth 601 fixedly connected to it. The heat is conducted downward to the support plate 1, and then dissipated through the increased surface area of ​​the heat dissipation grooves 605 on the lower surface of the support plate 1. Through this three-dimensional heat dissipation network that combines internal convection, external radiation and downward conduction, the overall heat dissipation performance is significantly improved.

[0034] In terms of installation and fixing, the process is divided into two stages. During installation, the first fixing plate 4 is aligned with the insulating mounting base 2. The limiting post 801 is inserted into the fixing hole 804 to provide initial guidance. Then, the first fixing plate 4 is pressed down, and the fixing block 807 enters the fixing hole 804. Its outer wall pushes the fixing ball 806 to compress the spring 805. When the slot on the fixing block 807 moves to the position aligned with the fixing ball 806, the fixing ball 806 quickly snaps into the slot under the elastic force of the spring 805, completing rapid elastic positioning. Subsequently, the threaded rod 803 is passed through the second fixing plate 802 and screwed into the internal thread of the insulating mounting base 2. Tightening the threaded rod 803 will apply a strong axial clamping force to the first fixing plate 4, so that it is firmly and finally locked with the insulating mounting base 2. This method, which combines elastic locking and threaded locking, not only ensures the convenience of installation but also ensures the long-term reliability of the connection, effectively solving the problem of structural loosening.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
