The importance of thermal management in LED lighting systems
The input power of high-power LED products is about 20% converted into light energy, and the remaining 80% is converted into heat energy. If a large amount of heat cannot be smoothly exported, the junction temperature of the LED chip will be too high, which will affect the service life of the product. Luminous efficiency and reliability. At this stage, the thermal bottleneck of the entire LED lighting system is concentrated on the interface between the LED device and the heat-conducting substrate, and then to the interface between the system boards. The excellent interface thermal conductive material can keep the LED heat dissipation channel unblocked, thus ensuring the normal illumination and service life of the LED.
The rapid development of LED packaging technology, the improvement of power and light efficiency of LED packaging products, prompted the cooling of LED lamps to put forward new requirements for interface thermal materials.
1. High thermal conductivity: The power of a single LED device increases, the heat generated is higher, and the temperature is higher. The thermal conductivity of the thermal conductive material is required to be higher than that of the OFweek semiconductor lighting network. The thermal conductivity of the interface thermal conductive material on the market is currently 0.8. W/mK ~ 3.5W / mK, the main substrate is a silicone material.
2, the operation is simple: the product can adapt to the production line, the operation process is suitable for manual or mechanical brushing process, and can meet the test and sales requirements in the shortest time.
3, stable performance: LED lighting products in long-term, high-temperature work, the performance of thermal materials will not change, thermal conductivity, electrical insulation properties, bonding properties, material color and other aspects will not change.
4, cost-effective: on the basis of maintaining excellent thermal conductivity products and high quality, it can reduce the cost of customers and improve the cost performance of LED lighting products.
Gold-cool.com, a technology and innovation company in the field of heat conduction and heat dissipation nano-products, is launching a new thermal silica film. This innovative technology is specially developed for thermal management in the new trend of LED lighting. It helps LED luminaires and lighting manufacturers to apply thickness-controlled thermally conductive silicone compounds more quickly and accurately on complex shaped substrates while ensuring excellent thermal conductivity and reduced production costs.
Today, the electronics industry faces increasingly serious challenges in thermal management. As designers and vendors become more inclined to design and produce electronic devices that are smaller, faster, and more capable, the resulting heat management becomes more difficult. The ever-decreasing equipment space and increasing operating frequency have caused the temperature of the equipment to rise, which may affect the performance and reliability of the equipment. To help electronics designers and manufacturers overcome these challenges, Coco Nano's thermal materials are specifically developed to address these challenges. Not only does Nano-Nano offer a broad line of leading thermal materials, but it also offers a complete line of high performance thermal adhesives, gap fillers and gels to meet key industry needs.
