Description

Technical Field

[0001] This utility model belongs to the field of LED driver power supply technology, and in particular relates to an LED driver power supply with overheat protection function. Background Technology

[0002] LED driver power supplies are power converters that convert power supply into specific voltage and current to drive LEDs to emit light. As a rapidly developing and widely used new type of light source, LED light sources have advantages over traditional light sources, such as energy saving, high efficiency, small size, long life, fast response speed, low driving voltage, and excellent shock resistance. As a result, they have been able to rapidly develop and expand the industry scale and market share. Under the guidance of industry trends, their technology is also constantly being updated and deepened. However, the biggest technical barrier restricting the development of LED light sources is the problem of heat conduction and heat sinking in LED packaging, that is, the heat dissipation problem of LEDs.

[0003] As a light source, LEDs typically need to operate continuously for extended periods. Even for a cold light source like LEDs, prolonged operation can generate a significant amount of heat. This necessitates efficient heat dissipation devices for LED light sources, capable of dissipating heat through short conduction paths to minimize damage to the chip caused by excessively high temperatures.

[0004] The current practice is to encapsulate the LED driver power supply onto the heat sink main bracket, with the power supply directly installed inside the frame without insulation, posing a safety hazard and resulting in poor heat dissipation. Alternatively, the power supply can be installed on a fixed box near the LED cabinet frame, which would block light and make wiring complicated. Utility Model Content

[0022] This utility model embodiment provides an LED driver power supply with overheat protection function, such as Figure 1-4As shown, the LED driver power supply with overheat protection function includes: a protective shell 1, with multiple exhaust ports on one side; multiple support plates 2, all fixed to the inner wall of the protective shell 1; a metal shell 3, fixed between the multiple support plates 2, located inside the protective shell 1; an insulating coating 4, disposed on the inner wall of the metal shell 3; a driver power supply body 5, disposed inside the metal shell 3; multiple air ducts 6, respectively disposed between the multiple support plates 2; a cooling fan 10, installed on the side of the protective shell 1 away from the multiple exhaust ports; and a protective component, disposed on the protective shell 1, used to isolate external foreign objects.

[0023] In this embodiment, the protective shell 1 serves as the outer protective structure of the entire driving power supply. Multiple exhaust ports are provided on one side to dissipate internally generated heat, improving heat dissipation efficiency. The design of the protective shell 1 not only provides physical protection but also optimizes heat dissipation performance through the exhaust ports. The support plate 2 supports and fixes other components. The metal shell 3 houses the driving power supply body 5, providing additional protection and aiding in heat conduction and dissipation. The insulating coating 4 effectively prevents current leakage or short circuits, improving safety. The driving power supply body 5 is the core component of the LED driving power supply. Through reasonable encapsulation and isolation, the driving power supply body 5 can operate stably, providing a stable power supply to the LED. The air duct 6 guides airflow, enhancing heat dissipation. The design of the air duct 6 optimizes the heat dissipation path and improves heat dissipation efficiency. The cooling fan 10 draws in cool outside air and dissipates heat through the air duct 6. The active cooling method of the cooling fan 10 significantly improves heat dissipation performance, ensuring the stable operation of the driving power supply.

[0024] In a further preferred embodiment of the present invention, the protective component includes a support shell 11 and a plurality of dustproof nets 12. The support shell 11 is detachably mounted on the protective shell 1 by bolts. The support shell 11 is sleeved outside the cooling fan 10. The plurality of dustproof nets 12 are respectively fixed inside the support shell 11 and the plurality of exhaust ports. The dustproof nets 12 are used to isolate impurities.

[0025] In this embodiment, the support shell 11 is detachably mounted on the protective shell 1 by bolts and is fitted over the cooling fan 10, providing additional protection for the cooling fan 10. At the same time, its detachable design facilitates maintenance and cleaning. The bolt fixing ensures a stable connection between the support shell 11 and the protective shell 1. The main function of the dust filter 12 is to isolate impurities, such as dust and small particles, to prevent them from entering the drive power supply, thereby protecting the internal components from contamination and damage. The dust filter 12 is installed at the exhaust port to ensure that external impurities are effectively prevented from entering while dissipating heat.

[0026] In a further preferred embodiment of the present invention, a temperature sensor 7 is installed on the top of the protective shell 1, and a detection plate 8 extending into the protective shell 1 is installed at the bottom of the temperature sensor 7. The detection plate 8 is in contact with the outer wall of the metal shell 3, and a handle 9 is hinged to the top of the protective shell 1.

[0027] In this embodiment, the temperature sensor 7 can monitor the temperature inside the protective shell 1 in real time, especially the temperature near the metal shell 3. This is crucial for preventing overheating and protecting the drive power supply. By acquiring temperature information in a timely manner, the overheat protection mechanism can be triggered to prevent damage or malfunction caused by excessive temperature. The design of the probe plate 8 ensures the accuracy and reliability of temperature measurement. Since the metal shell 3 is an important part of heat conduction, the probe plate 8 can accurately reflect the temperature status of the metal shell 3 and the internal drive power supply through direct contact with it. The design of the handle 9 improves the portability and ease of use of the drive power supply.

[0028] In a further preferred embodiment of the present invention, a housing 13 is installed on the side of the protective shell 1 away from the cooling fan 10. The housing 13 is provided with two power sockets 14. Each of the two power sockets 14 is equipped with a wire connected to the drive power supply body 5. The two power sockets 14 are used for inputting power and outputting power, respectively. A protective cover 16 for sealing the housing 13 is hinged to the protective shell 1.

[0029] In this embodiment, the housing 13 provides installation space for the power socket 14 and protects the power socket 14 from interference and damage from the external environment. By integrating the power socket 14 into the housing 13, the power interface of the entire power supply is cleaner and more orderly, and the safety of use is improved. The design of the power socket 14 allows the power supply to be easily connected to an external power source and output power to loads such as LED lights. The input power socket 14 is used to receive power provided from the outside, while the output power socket 14 provides the power converted by the power supply to the load. This design makes the power management of the power supply more flexible and efficient. The protective cover 16 is used to close the housing 13 and protect the power socket 14 from external factors such as dust and moisture.

[0030] In a further preferred embodiment of the present invention, an mounting plate 18 is installed on the protective cover 16, a fixing bolt 17 is threaded on the mounting plate 18, and a limiting hole 19 is provided on the protective shell 1, and the fixing bolt 17 can extend into the limiting hole 19.

[0031] In this embodiment, the design of the mounting plate 18 provides a stable support point for the fixing bolt 17, so that the protective cover 16 can be more firmly fixed to the protective shell 1. The fixing bolt 17 is a key component connecting the mounting plate 18 and the protective shell 1. By tightening it in the limiting hole 19, the protective cover 16 can be firmly fixed to the protective shell 1. This fixing method is not only simple and reliable, but also easy to disassemble and maintain.

[0032] In a further preferred embodiment of the present invention, a shock-absorbing pad 15 that can contact the protective cover 16 is installed on the side of the housing 13 near the protective cover 16, the protective cover 16 is provided with two cable ports, and the protective housing 1 is made of polyethylene.

[0033] In this embodiment, when the protective cover 16 is closed, the shock-absorbing pad 15 comes into contact with the protective cover 16. The design of the shock-absorbing pad 15 can absorb and disperse the impact force generated when the protective cover 16 is closed, thereby protecting the housing 13 and the internal power socket 14 from damage. This design not only improves the overall durability of the drive power supply, but also reduces the noise caused by vibration or impact, and improves the comfort of use. The design of the cable tray allows the wires or cables to pass neatly through the protective cover 16 and connect to the power socket 14. This not only improves the routing efficiency of the wires or cables, but also avoids the safety hazards caused by messy wires.

[0034] In a further preferred embodiment of the present invention, the cooling fan 10 is composed of a support frame 20, a motor 21 and a plurality of fan blades 22. The support frame 20 is mounted on the protective shell 1, the motor 21 is fixed inside the support frame 20, and the plurality of fan blades 22 are all mounted on the output shaft of the motor 21.

[0035] In this embodiment, the design of the support frame 20 provides a solid support for the motor 21 and the fan blades 22, ensuring that the cooling fan 10 can operate stably. The motor 21 is the core component of the cooling fan 10. By driving the fan blades 22 to rotate, airflow is generated, thereby achieving the heat dissipation effect. Selecting a high-performance, low-noise motor 21 can improve the heat dissipation efficiency of the cooling fan 10 and reduce noise pollution, thereby improving the overall performance of the drive power supply.

[0036] In summary, compared with related technologies, this device provides dual protection for the drive power supply body 5 by setting up a protective shell 1 and a metal shell 3, thereby increasing the safety of the equipment. The insulating coating 4 can effectively prevent short circuits and electric shocks. The cooling fan 10 and the air duct 6 can increase the heat dissipation effect of this device. The temperature sensor 7 can be used to achieve overheat protection.
