Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, and in particular to a high color rendering index iridescent LED lamp bead. Background Technology

[0002] High color rendering index (CRI) LED chips, with their superior light performance and rich color selection, are gradually replacing traditional lighting products and becoming an important part of modern lighting technology. The high CRI is a standard for measuring the ability of a light source to reproduce the true colors of objects. The application of high CRI in LED chips can effectively improve the color reproduction of the environment, allowing people to enjoy more realistic and natural light in their daily lives and work.

[0003] Traditional methods of connecting LED chip substrates and mounting plates are often cumbersome, requiring various complex tools and meticulous procedures to complete the installation. This not only demands a high level of skill from the installers but also significantly reduces installation efficiency. Especially during large-scale installations, time and labor costs increase substantially. Furthermore, due to the lack of an effective positioning mechanism, it is difficult to ensure precise alignment of the substrate and mounting plate during installation, leading to installation deviations and resulting in uneven LED chip arrangement, affecting the overall lighting effect and aesthetics. Therefore, a high color rendering index (CRI) RGB LED chip is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the connection between the traditional LED chip substrate and the mounting plate is usually cumbersome, requiring various complex tools and meticulous operating procedures to complete the installation. Therefore, this invention proposes a high color rendering index (CRI) iridescent LED chip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high color rendering index (CRI) LED bead, comprising a substrate and a mounting plate. A plurality of LED bead bodies are mounted on the surface of the substrate, and a plurality of toothed grooves are formed on the surface of the substrate. A plurality of toothed plates are fixedly connected to the surface of the mounting plate, and the toothed plates are slidably connected to the inner wall of the toothed grooves on the substrate. A U-shaped frame is fixedly connected to the surface of the substrate, and a fixing rod is fixedly connected to the inner surface of the U-shaped frame. A clamping plate is rotatably connected to the arc surface of the fixing rod, and two torsion springs are sleeved on the arc surface of the fixing rod. The two ends of the torsion springs are fixedly connected to the U-shaped frame and the clamping plate, respectively.

[0006] The effects achieved by the above components are as follows: the matching of the toothed groove and the toothed plate is unique and certain, ensuring that the substrate and the mounting plate can be accurately positioned in the preset position when connected, avoiding the situation where the lamp body is not aligned due to inaccurate installation position, thus affecting the overall lighting effect, ensuring the uniformity and consistency of the light emitted by the lamp body, and the structure composed of U-shaped frame, fixing rod, clamping plate and torsion spring plays an automatic clamping role, making the clamping plate press tightly on the mounting plate, forming a stable clamping force.

[0007] Preferably, two insert rods are slidably inserted into the U-shaped frame, and one end of each insert rod is fixedly connected to an elliptical plate.

[0008] The effect achieved by the above components is: the pull plate rotates on the arc surface of the fixed rod, pushing the insertion rod to slide inside the U-shaped frame until the insertion rod blocks the pull plate, so as to facilitate the quick disassembly of the base plate and the mounting plate.

[0009] Preferably, a spring is fitted onto the arc surface of the rod, and the two ends of the spring are fixedly connected to the elliptical plate and the U-shaped frame, respectively.

[0010] The effect achieved by the above components is that the spring itself drives the insertion rod to slide within the U-shaped frame and automatically block the card plate.

[0011] Preferably, a plurality of heat dissipation fins are fixedly connected to the surface of the substrate.

[0012] The effect achieved by the above components is that the heat dissipation fins have a large surface area and a wide contact area with the air, which greatly accelerates the transfer of heat from the lamp bead body to the air and effectively reduces the overall temperature of the lamp bead body.

[0013] Preferably, the surface of the substrate has a plurality of ventilation holes.

[0014] The effect achieved by the above-mentioned components is that the presence of the exhaust vent provides a channel for hot air to be discharged smoothly, while external cold air can be replenished in a timely manner.

[0015] Preferably, the surface of the heat dissipation fins is coated with a heat dissipation layer.

[0016] The effect achieved by the above components is that the heat dissipation coating adopts graphene heat dissipation coating, which can further enhance the heat radiation capacity of the heat dissipation fins and improve heat dissipation efficiency.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, the matching of the toothed groove and the toothed plate is unique and definite, ensuring that the substrate and the mounting plate can be accurately positioned in the preset position when connected. This avoids the situation where the lamp body is not aligned due to inaccurate installation position, which would affect the overall lighting effect. It ensures the uniformity and consistency of the light emitted by the lamp body. The structure composed of U-shaped frame, fixing rod, clamping plate and torsion spring plays an automatic clamping role, so that the clamping plate is pressed tightly on the mounting plate to form a stable clamping force.

[0024] Reference Figure 1-4As shown, this utility model provides a technical solution: a high color rendering index (CRI) LED bead, comprising a substrate 1 and a mounting plate 2. A plurality of LED bead bodies 13 are mounted on the surface of the substrate 1, and a plurality of toothed grooves are formed on the surface of the substrate 1. A plurality of toothed plates 3 are fixedly connected to the surface of the mounting plate 2, and the toothed plates 3 are slidably connected to the inner wall of the toothed grooves of the substrate 1. A U-shaped frame 4 is fixedly connected to the surface of the substrate 1, and a fixing rod 5 is fixedly connected to the inner surface of the U-shaped frame 4. A clamping plate 6 is rotatably connected to the arc surface of the fixing rod 5, and two torsion springs 7 are sleeved on the arc surface of the fixing rod 5. The two ends of the torsion springs 7 are fixedly connected to the U-shaped frame and the clamping plate 6, respectively. The unique and deterministic fit between the toothed groove and the toothed plate 3 ensures that the substrate 1 and the mounting plate 2 are precisely positioned during connection, preventing misalignment of the LED bodies 13 due to inaccurate installation and thus affecting the overall lighting effect. This ensures the uniformity and consistency of the light emitted by the LED bodies 13. The structure consisting of a U-shaped frame, a fixing rod 5, a clamping plate 6, and a torsion spring 7 provides automatic clamping, pressing the clamping plate 6 firmly onto the mounting plate 2 to form a stable clamping force. Two insert rods 8 are slidably inserted into the U-shaped frame 4, with one end of the insert rod 8 fixedly connected to an elliptical plate 9. Pulling the clamping plate 6 to rotate on the arc surface of the fixing rod 5 pushes the insert rod 8 to slide within the U-shaped frame 4 until the insert rod 8 blocks the clamping plate 6, facilitating quick disassembly between the substrate 1 and the mounting plate 2. A spring 10 is fitted onto the arc surface of the insert rod 8, with both ends of the spring 10 fixedly connected to the elliptical plate 9 and the U-shaped frame 4, respectively. The spring 10, through its own elastic force, drives the insertion rod 8 to slide within the U-shaped frame 4, automatically blocking the card plate 6. Several heat dissipation fins 11 are fixedly connected to the surface of the substrate 1. The heat dissipation fins 11 have a large surface area and a wide contact area with the air, greatly accelerating the transfer of heat from the LED bead body 13 to the air, effectively reducing the overall temperature of the LED bead body 13. Several exhaust holes 12 are provided on the surface of the substrate 1. The exhaust holes 12 provide a channel for hot air to escape smoothly, while allowing external cool air to replenish in a timely manner. The surface of the heat dissipation fins 11 is coated with a heat dissipation layer. The heat dissipation coating uses graphene heat dissipation paint, which further enhances the heat radiation capacity of the heat dissipation fins 11 and improves heat dissipation efficiency.

[0025] Working principle: When the operator assembles the substrate 1 and the mounting plate 2, pushing the substrate 1 moves the heat dissipation fins 11 towards the mounting plate 2. The heat dissipation fins 11 have a large surface area and a wide contact area with the air, which greatly accelerates the transfer of heat from the lamp bead body 13 to the air, effectively reducing the overall temperature of the lamp bead body 13. This continues until the toothed plate 3 slides against the inner wall of the toothed groove of the substrate 1, pulling the elliptical plate 9 to move the insertion rod 8 within the U-shaped frame 4 until the insertion rod 8 no longer obstructs the clamping plate 6. At this point, the torque of the torsion spring 7 causes the clamping plate 6 to move against the fixing rod 5. The arc surface slides automatically into the slot of the substrate 1. The matching of the toothed groove and the toothed plate 3 is unique and deterministic, ensuring that the substrate 1 and the mounting plate 2 can be accurately positioned in the preset position when connected. This avoids the situation where the lamp body 13 is not aligned due to inaccurate installation position, which would affect the overall lighting effect. It ensures the uniformity and consistency of the light emitted by the lamp body 13. The structure composed of U-shaped frame, fixing rod 5, clamping plate 6 and torsion spring 7 plays an automatic clamping role, so that the clamping plate 6 is pressed tightly on the mounting plate 2, forming a stable clamping force.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
