Description

Technical Field

[0001] This utility model relates to the field of LED power supply technology, specifically to an LED power supply heat dissipation and protection structure. Background Technology

[0002] An LED power supply is a device that converts the voltage and current input to the mains grid into a stable, low voltage and current suitable for the operation of LED chips. It typically features overvoltage, overcurrent, and short-circuit protection to ensure stable light emission under various operating conditions. Heat dissipation plays a crucial role because LEDs convert electrical energy into light and heat during operation. If heat cannot be effectively dissipated, the junction temperature of the LED will rise, reducing luminous efficacy, shortening lifespan, and even decreasing brightness and stability. Therefore, excellent heat dissipation design (such as heat sinks, thermally conductive materials, air cooling or forced air cooling, and thermal interface materials) can reduce junction temperature, improve efficiency and lifespan, and reduce the impact of power loss on power supply performance. In short, the LED power supply is responsible for providing a stable drive current, while heat dissipation is a prerequisite for ensuring stable output of this current; both are indispensable.

[0003] However, existing LED power supplies operate at excessively high temperatures and have poor heat dissipation, leading to luminous flux attenuation, color temperature drift, shortened lifespan, and reduced efficiency or even protection triggers in the drive circuit due to heat. This increases the risk of thermal runaway in the lamps and significantly reduces their reliability and safety. To address these issues, the inventors propose an LED power supply heat dissipation and protection structure. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] like Figure 1-5 As shown, this utility model provides a heat dissipation and protection structure for an LED power supply, including a heat dissipation box 1. The heat dissipation box 1 has a first heat dissipation cavity 11 and a second heat dissipation cavity 12. The first heat dissipation cavity 11 is used to absorb and dissipate heat from the side of the LED power supply body 4. Several fixing plates 2 are fixedly installed on the inner wall of the first heat dissipation cavity 11, forming an air inlet slot 21 between the first heat dissipation cavity 11 and the fixing plates 2. The fixing plates 2 create a Z-shaped through slot within the first heat dissipation cavity 11, allowing air to circulate and efficiently remove heat. Several first heat dissipation fins 23 are fixedly installed on the inner wall of the first heat dissipation cavity 11, and second heat dissipation fins 24 are fixedly installed on the inner wall of the second heat dissipation cavity 12. Fins 23 and second heat dissipation fins 24 can absorb heat and carry away the absorbed heat with the air, thus completing the heat dissipation. A protective component 3 is installed on the outside of the heat dissipation box 1 to protect the device. There are two first heat dissipation chambers 11, which are connected to the second heat dissipation chamber 12. The air inlet slot 21 is connected to the second heat dissipation chamber 12, so that the gas in the first heat dissipation chamber 11 can be circulated into the second heat dissipation chamber 12 to improve the heat dissipation effect. An intake fan 22 is installed on the inner wall of both air inlet slots 21, and an exhaust fan 25 is installed in the second heat dissipation chamber 12. The intake fan 22 and the exhaust fan 25 can control the air intake and exhaust in the heat dissipation box 1.

[0021] The protective component 3 includes a mounting plate 31, which is fixedly installed on the outside of the heat sink box 1. Several arc-shaped plates 32 are fixedly provided on the outside of the mounting plate 31. A protective plate 33 is fixedly connected to the side of the arc-shaped plates 32 away from the mounting plate 31. The protective plate 33 has circular holes 34 arranged in an array inside.

[0022] By adopting the above technical solution, the heat sink 1 can be protected, which in turn can protect the LED power supply body 4, preventing damage to the heat sink 1 and the LED power supply body 4 caused by bumps and knocks.

[0023] The heat sink 1 includes a housing 13 and a cover plate 14, which is detachably mounted on the outside of the housing 13 by screws.

[0024] By adopting the above technical solution, the inside of the heat sink box 1 can be easily maintained by disassembling the cover plate 14.

[0025] A second mesh plate 27 is detachably installed on the outside of the heat sink 1. The second mesh plate 27 is located outside the exhaust fan 25.

[0026] By adopting the above technical solution, the second mesh plate 27 can prevent dust from entering the heat sink box 1.

[0027] A first mesh plate 26 is detachably installed on the outside of the heat sink 1, and the first mesh plate 26 is located on the side of the intake fan 22.

[0028] By adopting the above technical solution, the No. 1 mesh board 26 can prevent Hu Chen from entering the heat sink box 1.

[0029] Mounting plate 31 is detachably mounted on the outside of heat sink 1 using screws.

[0030] By adopting the above technical solution, the mounting plate 31 and its outer structure can be installed and disassembled.

[0031] Both the heat sink 1 and the mounting plate 2 are made of aluminum.

[0032] By adopting the above technical solutions, aluminum metal materials are lighter, while improving thermal conductivity and heat dissipation.

[0033] The curved plate 32 is made of elastic metal.

[0034] By adopting the above technical solution, the flexible arc plate 32 can buffer the device of the protective plate 33, thereby achieving the protective effect.

[0035] Working principle: First, the heat sink 1 is installed on the outside of the LED power supply body 4. The heat generated inside the LED power supply body 4 is transferred to the first heat sink fin 23 and the second heat sink fin 24 through the heat sink 1. Then, the intake fan 22 is activated, which draws air from outside the device into the air intake slot 21. The air passing through the air intake slot 21 can carry away the heat attached to the outside of the first heat sink fin 23, and then enters the second heat sink cavity 12. The exhaust fan 25 extracts the air from the second heat sink cavity 12. The intake fan 22 and the exhaust fan 25 can accelerate the air circulation in the heat sink 1, thereby improving the heat dissipation effect, enhancing the light efficiency and stability, extending the service life, and reducing the impact of power loss on the power supply performance. When the device is subjected to an external impact, the protective plate 33 will move first, and the protective plate 33 can protect against the impact. When the protective plate 33 is compressed, the arc plate 32 can dilute the pressure, thereby protecting the heat sink 1 and the LED power supply body 4.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
