As a widely used lighting tool in life, LED lights are favored by consumers because of their environmental protection, energy saving, stable lighting, and soft lighting. However, the biggest technical problem in the development of LED lighting at present is the heat dissipation problem. Poor heat dissipation performance will limit the development of LED lamp driving power, chips, circuit boards and other structures, and cause premature LED lamp decay.

In order to solve the problem of poor LED heat dissipation performance, LED lamp heat sinks that help LED lamps dissipate heat have appeared on the market. However, LED heat sink manufacturers will have differences in scale, strength, and efficiency. The quality of the LED heat sinks produced and processed And there will be differences in performance. This article starts from the common problems when LED radiator manufacturers process LED radiators, and comes to Dongguan Zhigao Industrial to introduce the precautions of LED radiator manufacturers when processing LED light radiators.

1. Choose the right raw materials. The raw materials selected by various LED radiator manufacturers in the processing of LED radiators in the market are different. The common raw materials used to manufacture and process LED radiators on the market are plastic, ceramic, metal and Graphene. LED heat sinks made of plastics and ceramics have advantages in plasticity and price cost. Although the heat conduction and heat dissipation performance is worse than other materials, low-power LED lamp heat sinks can well meet the heat dissipation requirements. Metal is the most widely used material for making and processing LED heat sinks. Among them, aluminum alloy is more popular among manufacturers. This is because aluminum alloy is not only excellent in heat conduction and heat dissipation, but also has light weight, easy processing and affordable price. Features, very suitable for making heat sinks for high-power LED lights. Graphene's most new type of semiconductor thermal conductive material, super thermal and heat dissipation performance and ultra-light quality make it a new focus of the LED heat sink industry, but the use of graphene to process LED heat sinks requires professional and mature processing capabilities, and the price Higher, so it has not yet been popularized. Therefore, when LED radiator manufacturers help customers to process LED light radiators, they should pay attention to choosing different raw materials according to different LED light heat dissipation requirements. This is not only to manufacture LED radiators that meet the requirements, but also from the perspective of customers. Help them festival省成本。

2. Ensuring sufficient contact area. Different LED lamps have different requirements on the size and shape of the radiator. LED radiator manufacturers will use different processing techniques to shape radiators with different shapes of shells during processing. It is to fit perfectly with LED lights. Although the radiators are different in size and shape, they are inseparable. The general principle of design and processing cannot be changed, that is, to ensure that there is a sufficient contact area with the lamp and the air. The fin-shaped heat sink and the sun tube radiator are representative works that make good use of this principle. Both of them increase the contact area with the LED lamp in a limited space, which can help the LED lamp absorb more Heat, to achieve efficient heat conduction; at the same time, the convection area between the radiator and the air is increased, so that the radiator can dissipate the heat into the air in the shortest time. Therefore, LED radiator manufacturers must ensure the rationality of the shape of the radiator when processing, not only to ensure that the appearance is novel and unique, unconventional, but also to ensure excellent heat dissipation performance.

3. Ensuring the overall stability The LED light radiator must not only have excellent heat dissipation capacity, but also ensure that the overall stability is strong and have a long service life. This is based on the processing and shaping of the radiator. When manufacturers make LED heat sinks with complex shapes, especially for heat sinks that require large-area bending, the processing techniques used by each will be quite different. The traditional method used to make and process this type of LED heat sink is welding and molding. The contact area is increased by welding small heat sinks on the motherboard. This method does not require too high processing costs, but in But it will leave hidden dangers on stability. Because the welding forming is a test of the manufacturer's welding technology, once the welding is not tight enough, the welding place is easily corroded, which not only affects the overall heat dissipation capacity of the LED radiator, but also easily breaks. In order to improve the structural stability of the LED radiator, many LED radiator manufacturers on the market have gradually begun to use the technology of integral stretching and forming. Under the precise control of CNC machining, the LED radiator is stretched and formed by a mold. It can effectively reduce the existence of welds, or even no welds. The LED radiator without welding gap is not only more beautiful, but also less prone to this period. The overall stability and service life have been greatly improved.

LED radiator manufacturers need to consider comprehensively when processing LED radiators, pay attention to details, ensure the rationality of the overall design and processing of LED radiators, ensure that there are no shortcomings in the quality of radiators, and help manufacturers establish a senior professional in the minds of customers The image of LED heat sink processing plant.
