With the continuous development of LED technology, high-power LEDs are increasingly used in the field of lighting. However, the high heat problem brought by high-power LEDs has also become prominent, which puts higher requirements on the thermal conductivity of lighting ring aluminum substrate.As a key component of LED heat dissipation, the thermal conductivity of lighting ring aluminum substrate directly affects the heat dissipation effect and service life of LED. In order to optimize the thermal conductivity of lighting ring aluminum substrate, we can start from multiple aspects.First, in terms of material selection, aluminum alloy materials with better thermal conductivity can be selected, such as 2024 aluminum alloy, which has a higher thermal conductivity coefficient and better heat dissipation effect. At the same time, the thickness of the aluminum substrate should also be appropriately increased to improve its heat dissipation capacity, but it should be noted that it should not affect the packaging thickness of the LED.Secondly, in terms of the surface coating of the aluminum substrate, materials with high reflectivity, such as polymers, siloxanes, etc., can be selected to improve the ability to reflect light, reduce energy loss, and indirectly improve the heat dissipation effect.Furthermore, optimizing the design and layout of heat dissipation holes is also the key to improving the thermal conductivity of lighting ring aluminum substrate. By rationally designing the size, number and distribution of the heat dissipation holes, the heat dissipation channel can be kept unobstructed, the thermal diffusion coefficient can be improved, and the heat can be dissipated in a timely and effective manner.In addition, the use of advanced production processes and processing technologies, such as laser cutting and precision milling, can also improve the precision and surface finish of the lighting ring aluminum substrate, thereby further improving its thermal conductivity.In summary, optimizing the thermal conductivity of the lighting ring aluminum substrate requires starting from multiple aspects such as material selection, surface coating, heat dissipation hole design, and production process. Only in this way can the heat dissipation requirements of high-power LEDs be met, the long-term stable operation of LEDs can be ensured, and their service life can be extended. With the continuous advancement and innovation of technology, it is believed that the thermal conductivity of the lighting ring aluminum substrate will be further improved in the future, injecting new vitality into the development of the LED lighting field.
