[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6This utility model provides an embodiment of a low-temperature rise LED, including a lampshade 1. The lampshade 1 plays a crucial role in protecting internal components and optimizing light distribution, preventing external dust, moisture, and other impurities from entering and causing damage to the delicate internal light-emitting and electrical components. Its unique shape design allows the light emitted by the LED chip 8 to be scattered more evenly, meeting the needs of different lighting scenarios. An end base 2 is provided on the lower surface of the lampshade 1, serving as the supporting foundation for the entire device. Pins 3 are fixedly connected inside the end base 2, acting as an important bridge for electrical connection. One end is fixedly connected inside the lamp holder 7, responsible for accurately introducing external power to stably power the LED chip 8 on the lamp holder 7, ensuring its continuous light emission. The lamp holder 7 is fixedly connected inside the end base 2, directly supporting the core component, the LED chip 8. It not only provides physical support for the LED chip 8, ensuring its stability during operation, but also has a certain heat dissipation function, helping to dissipate the heat generated during chip operation and extending the chip's lifespan. An LED chip 8 is fixedly connected to the upper surface of the lamp holder 7. A fixing component is installed inside the end base 2 to achieve a convenient and reliable connection between the lampshade 1 and the end base 2. The fixing component includes a fixing block 5, whose side wall is fixedly connected to the side wall of the lampshade 1. A sliding groove 6 is provided inside the end base 2, providing precise guidance for the sliding of the fixing block 5. A fixing seat 9 is fixedly connected inside the end base 2. A spring 10 is installed inside the lampshade 1, with one end fixedly connected to the side wall of fixing seat 9 and the other end fixedly connected to fixing seat 11. The spring 10 utilizes its elastic properties to buffer and reset during the installation and removal of the lampshade 1. A top plate 12 is fixedly connected to the upper surface of fixing seat 11. The top plate 12 is linked to the spring 10. When the lampshade 1 is pressed down, the top plate 12 receives pressure from the lampshade 1, triggering a specific engagement state between the fixing block 5 and the sliding groove 6 through its own displacement, thus achieving convenient locking and unlocking of the lampshade 1. The side wall of the fixing block 5 is slidably connected to the inside of the slide groove 6, and the side wall of the top plate 12 is slidably connected to the inside of the end seat 2. When the side wall of the fixing block 5 slides into the inside of the end seat 2, its side wall is in contact with the upper surface of the top plate 12. The end seat 2 is also equipped with a heat dissipation component, which can dissipate the heat generated by the LED chip 8 when it is working in time, and avoid problems such as light decay, shortened life or even damage to the chip due to overheating.
[0040] When equipment maintenance is required, the lampshade 1, acting as the first barrier to cover and protect internal components, initiates the separation process by pressing down on it. The downward movement of the lampshade 1 causes the connected fixing block 5 to move synchronously. The fixing block 5 is a key structural component for locking and unlocking the lampshade 1 and the end seat 2. It is tightly fitted inside the slide groove 6 and cooperates with the slot within the slide groove 6. Under normal operating conditions, the slot firmly holds the fixing block 5, ensuring that the lampshade 1 is securely mounted on the end seat 2. This effectively prevents the lampshade 1 from shifting or falling off due to accidental shaking or collision, providing reliable protection for the internal LED chip 8 and other precision components. As the fixing block 5 moves downward, it exerts pressure on the top plate 12. The top plate 12, located at a specific position below the lampshade 1, plays a crucial role in transmitting force. It bears the pressure from the fixing block 5 and transmits this force to the connected spring 10. Spring 10 is an elastic buffer and energy storage component in the entire separation mechanism. When subjected to pressure transmitted from the top plate 12, spring 10 contracts according to its elastic properties, storing this energy to provide necessary elastic assistance for the subsequent repositioning of the lampshade 1 or other operations. Simultaneously, during the disassembly of the lampshade 1, the contraction of spring 10 also acts as a buffer, preventing damage to components caused by sudden external impacts. Next, the lampshade 1 is rotated. Since the fixing block 5 has been released from the slot, the lampshade 1 can rotate smoothly around a certain axis, allowing the fixing block 5 to slide along the trajectory of the slide groove 6 to the edge of the slide groove 6. This step fully utilizes the guiding function of the slide groove 6, which provides a precise path for the movement of the fixing block 5, ensuring that the fixing block 5 does not wobble or deviate from the correct direction after being released from the slot, thus ensuring the orderly progress of the entire disassembly process. Then, by pulling the lamp cover 1 upwards, it can be separated from the end base 2, thereby completely opening the equipment casing and exposing the internal LED chip 8 without any obstruction. This greatly facilitates the technicians in inspecting the LED chip 8. Whether it is checking the chip's light-emitting performance, heat dissipation, or troubleshooting possible electrical faults, it becomes simple and easy, effectively improving maintenance efficiency, shortening equipment downtime, and ensuring that the equipment can be restored to normal operation in a timely manner.
[0041] Reference Figure 1 and Figure 5The heat dissipation component includes a heat-conducting plate 13, which acts as a crucial heat conduction bridge. Made of silicone, which possesses excellent flexibility and conformability, its upper surface can tightly adhere to the lower surface of the lamp holder 7, ensuring a seamless connection that allows heat to be efficiently conducted from the lamp holder 7 to the heat-conducting plate 13. A heat sink 14 is fixedly connected to the lower surface of the heat-conducting plate 13; this tight connection ensures continuous heat transfer, further conducting heat from the lamp holder 7 downwards. A heat sink fin 15, made of aluminum, is fixedly connected inside the end base 2. This fin effectively increases the heat dissipation area, accelerating heat dissipation into the air and significantly reducing the temperature of the LED chip 8, ensuring stable operation of the LED chip 8 in a suitable temperature environment. The upper surface of the heat sink fin 15 is in contact with the heat sink 14, ensuring that heat conducted from the heat sink 14 smoothly enters the heat sink fin 15, further optimizing the heat transfer path and improving heat dissipation efficiency. A protective mesh 16 is fixedly connected inside the end base 2. The protective mesh 16 is attached to the heat sink fins 15. The protective mesh 16 has a dual protective function. On the one hand, it can block external dust, impurities and other foreign objects from entering the interior of the end base 2, preventing these foreign objects from adhering to the heat sink fins 15 and affecting the heat dissipation effect. A protective sleeve 4 is fixedly connected to the side wall of the pin 3. The protective sleeve 4 is made of rubber material. Rubber has excellent flexibility. During daily use, transportation or installation, when the pin 3 is subjected to external impact, the protective sleeve 4 can buffer the external force with its own elasticity to prevent the pin 3 from bending or breaking due to external force. The integrity of the pin 3 is guaranteed, thereby ensuring that the electrical connection of the entire LED light-emitting diode is stable and reliable, and will not cause open circuit or other faults due to damage to the pin 3, maintaining normal power-on and light-emitting function.
[0042] During equipment operation, the continuous operation of the LEDs inevitably generates a large amount of heat. At this time, the lamp holder 7, as a key component supporting the LED chip 8 and other related components, absorbs some heat during operation. The LED chip 8 is also the primary source of heat generation. The heat generated by both urgently needs efficient dissipation; otherwise, it will seriously affect the equipment's performance and lifespan. The heat-conducting plate 13 plays a crucial role in this heat dissipation process. It is tightly attached to the lower surface of the lamp holder 7. Thanks to the excellent thermal conductivity and adhesion properties of its silicone material, it can quickly and accurately absorb the heat generated by the lamp holder 7, while also collecting every bit of heat from the LED chip 8, ensuring comprehensive heat collection and laying a solid foundation for subsequent heat dissipation steps. Next, the heat-conducting plate 13 transfers the collected heat to the heat sink 14. The heat sink 14 and the heat-conducting plate 13 are firmly connected, forming a smooth heat transfer channel, allowing heat to flow unimpeded from the heat-conducting plate 13 to the heat sink 14, further expanding the heat diffusion range and paving the way for efficient heat dissipation by the subsequent heat sink fins 15. Subsequently, the heat sink 14 transfers heat to the heat dissipation fins 15. The heat dissipation fins 15 are made of aluminum, whose high thermal conductivity allows for rapid and even distribution of heat received from the heat sink 14 throughout its structure. Their carefully designed fin structure significantly increases the contact area with the air, enabling rapid heat exchange and accelerating heat dissipation. Finally, the protective mesh 16 not only protects the heat dissipation fins 15 from external interference but also features ventilation holes, providing an outlet for the final heat dissipation. Heat is continuously transferred out through the ventilation holes of the protective mesh 16, forming a complete closed loop in the entire cooling system. This achieves ideal heat dissipation, effectively reducing malfunctions such as flickering and shutdown caused by overheating, ensuring stable and continuous equipment operation, significantly extending equipment lifespan, and improving reliability.
[0043] Working principle: During the operation of this device, a large amount of heat is generated. At this time, the heat generated by the lamp holder 7 and the LED chip 8 is absorbed by the heat conduction plate 13. Then, the heat conduction plate 13 transfers the heat to the heat sink 14, and then the heat sink 14 transfers it to the heat sink fins 15. Finally, the heat is transferred out through the heat dissipation holes of the protective mesh 16, thereby achieving the heat dissipation effect and effectively reducing malfunctions such as flickering and going out caused by excessive temperature. When the device needs to be repaired, press down on the lamp cover 1 to make the fixing block 5 disengage from the slot inside the slide 6. At the same time, when the fixing block 5 moves down, it will squeeze the top plate 12, thereby causing the spring 10 to contract. Then, rotate the lamp cover 1 to let the fixing block 5 slide to the edge of the slide 6. Then, pull the lamp cover 1 upward to separate it from the end seat 2, which facilitates the repair of the LED chip 8.
