Extrusion aluminum heating sink is used to dissipate heat generated by electronic components such as transistors, diodes, and integrated circuits. The heat sink is attached to the component using thermal adhesive or thermal grease, which helps transfer heat from the component to the heat sink. The extrusion aluminum heat sink has a large surface area, which increases the rate of heat dissipation. The fins on the heat sink increase the surface area even further, allowing for more efficient cooling. The extrusion aluminum heat sink is commonly used in electronic devices such as computers, LED lights, and power supplies.

A heat sink is a device that is used to dissipate heat from electronic components by increasing the surface area of the component and allowing the heat to be transferred to the surrounding air. The specification of a heat sink includes the following parameters:
1. Thermal Resistance: This is the measure of how effectively the heat sink can transfer heat away from the component. It is measured in degrees Celsius per watt (°C/W). A lower thermal resistance indicates a more efficient heat sink.
2. Thermal Conductivity: This is the measure of how well the heat sink material conducts heat. It is measured in watts per meter-kelvin (W/mK). Materials with higher thermal conductivity are more effective at transferring heat.
3. Fin Density: This is the number of fins on the heat sink per unit of length. A higher fin density increases the surface area of the heat sink and improves its ability to dissipate heat.
4. Fin Thickness: This is the thickness of the fins on the heat sink. Thicker fins can absorb more heat but may also impede airflow.
5. Base Thickness: This is the thickness of the base of the heat sink that makes contact with the component. A thicker base can absorb more heat but may also increase thermal resistance.
6. Material: Heat sinks can be made from a variety of materials including aluminum, copper, and graphite. The choice of material depends on the specific application and the desired thermal properties.
7. Size and Shape: The size and shape of the heat sink depend on the size and shape of the component it is intended to cool. Larger components require larger heat sinks with more surface area.
Overall, the specification of a heat sink is critical to ensuring that electronic components operate within their temperature limits and maintain their reliability and lifespan.

1. Analyze the high-power LED market from the main application market of high-power LED - landscape lighting. As the largest application market of LED lighting, the landscape lighting market accounts for about 43%. Its new round of rapid growth will certainly drive the rapid development of the overall LED lighting industry. Some large and medium-sized cities, such as Shanghai, Xiamen, Beijing, Dalian and Nanchang, have completed a considerable number of LED lighting demonstration projects.
2. The successful completion of these demonstration projects in large and medium-sized cities and the successful application in the Olympic venues indicate that the technology of LED lighting in landscape lighting has gradually matured. Whether at home or abroad, the landscape of a city is a landmark building product of a city, and neon lights as landscape lighting are gradually replaced by LED landscape lights around the world due to energy, energy conservation, environmental protection and other issues. There are about 700000 cities around the world, and the huge economic benefits generated by these lights are unpredictable based on the calculation of 5000 lights in a city and about 1000 yuan for a lamp.
3. Driver is the core component of LED lighting. With the maturity of LED chip technology, the quality of LED light source has been very reliable. In many cases, the fault of LED lamps is from the driver. High-power LED drive power supply is an emerging industry, and has not formed a centralized industrial cluster. Therefore, the regional nature is not obvious. And the number of enterprises entering the industry is not large, so the degree of competition is low.
4. The efficiency of led driver is very high, which can fully help us achieve the desired effect. Of course, in the process of using it, don't underestimate its security. No matter how you use it, even if you work for a long time, it will not have any security risks. Of course, the life of the led driver is limited. It is better to replace a new led driver every few years, so that its work efficiency will be better. If you want to better understand its function, you'd better use it yourself.

Geometric accuracy includes shape accuracy, geometric accuracy of mutual position and geometric accuracy of relative motion. The surface shape of the workpiece processed on the lathe depends on the relative motion path between the tool and the workpiece, and the tool and the workpiece are directly driven by the executive part of the CNC lathe. Therefore, the geometric accuracy of the CNC lathe is the basic condition to ensure the machining accuracy. Each type of digital control lathe has its own geometric accuracy requirements. Geometric accuracy generally includes: axial rotation of the main shaft, radial circular run-out of the main shaft, mutual perpendicularity of the movement of each coordinate direction, the equal height of the main shaft taper hole axis and the tailstock taper hole, etc

LED lights need to be protected by the driver. The main reasons are as follows:
1. Because LED is a characteristic sensitive semiconductor device and has negative temperature characteristics, LED driver power supply (also called driver) is to protect its stable working state during the application process.
2. LED devices have almost strict requirements for driving power supply. Unlike ordinary incandescent bulbs, LEDs can be directly connected to 220V AC mains power. LED is driven by low voltage. It is necessary to design complex conversion circuit. Different LED lamps for different purposes should be equipped with different power adapters.
3. To design a good power supply, we must comprehensively consider the factors of efficiency conversion, effective power, constant current accuracy, power supply life, and electromagnetic compatibility, because the role of power supply in the whole lamp is as important as that of human heart.
