LED lights are often widely used in our daily lives because they have the characteristics of stable lighting, energy saving, environmental protection, and soft light. Therefore, LED is applied in various fields such as residential lighting, commercial lighting, industrial lighting, agricultural lighting, and medical lighting.
In high-power LED lights, we often see circular aluminum shells on the LED lights. Many people think that these aluminum shells are just for decorative purposes, but in fact, they have many uses.
The aluminum shells are not only visually striking, but also as an important component of LED lights.
Why LED lights need heat sink?
Although LED lights have superior functions and features compared to traditional lighting, they generate a large amount of heat during operation. If the heat is not dissipated in a timely, it will deteriorate the LED lighting environment, affect the brightness of LED lighting, and even threaten the service life of LED lights. The aluminum heat sink shell of LED lights can help them dissipate heat efficiently.
SUN FLOWER heat SINK DESIGN
Most LED lights use a sunflower design, which is circular in shape with fins spreading from the inside to outside, some in a clockwise shape, and some in a straight line outward. This design is not only aesthetically pleasing, but also allows the heat sink to increase the contact area with the LED light source and increase the surface area for heat dissipation, thereby increasing the contact area between heat and air and accelerating the heat dissipation effect. Enable LED lights to maintain a stable working environment.
Generally, extrusion processing is used for this sunflower heat sink, with shapes such as circular, square, or other shapes. It is made in the shape of a sunflower, which can increase the contact between the radiator and the air, and the heat is transmitted to the surroundings of the radiator through the outside of the center. Its shape allows it to receive more winds evenly and smoothly, and dissipate heat more evenly. This heat dissipation effect is very fast and significant.
Sunflower heat sink can also be divided into 2 types in terms of finished product structure:
Solid Sunflower Heat Sink: The middle is made of aluminum, and the fins radiate outward. If a fan and retaining ring are installed on this heat sink, it can become a finished heat sink;
Copper plug/heat pipe sunflower Heat Sink: This heat sink has solid copper or large-diameter copper pipes, with copper pipes inserted in the middle for better thermal conductivity. The copper substrate is in contact with the chip, and heat is conducted to the sunflower through the solid copper in the middle, dissipating heat on the heat sink.
