摘　　要：固态照明器件(白光LED/激光照明)具有发光效率高、节能环保、结构设计灵活和使用寿命长等显著优势,在室内外照明、汽车大灯、现代农业、医疗和显示等领域有广阔的应用前景。散热技术作为固态照明应用的关键,直接决定了器件的服役性能和发光品质等技术参数。重点总结了固态照明器件散热技术的最新研究进展,系统分析了传统白光LED、远程激发型白光LED和激光照明等散热器的工作原理、结构设计和散热方式(自然对流、强制对流、热管散热、液冷散热和其他散热方式),阐述了散热器的热阻、散热路径、热耗散速率、轻量化以及光转换元件热传导等调控方法。最后,讨论了固态照明器件亟需解决的高发光通量、远程激发模式、散热和封装一体化设计等问题,并展望了固态照明器件散热技术的发展趋势。Solid-state lighting devices, such as white light LED and laser lighting, have distinct advantages of energy saving, environmentally friendly, long service life and high luminescence efficiency, which have broad application prospects in indoor and outdoor lighting, automotive headlights, modern agriculture, medical and display fields. As the key of solid-state lighting application, heat dissipation technology directly determines the service performance and luminescence quality of devices. It reviews the latest research progress of heat dissipation technology for solid state lighting devices. The working principle, structure design and heat dissipation modes(natural convection, forced convection, heat pipe heat dissipation, liquid cooling and other heat dissipation modes) of traditional white LED, remote excitation white LED and laser lighting are summarized. The control methods of heat resistance, heat dissipation path, heat dissipation rate, lightweight and heat conduction of optical conversion elements are analyzed. Finally, the urgent problems of high luminous flux, remote excitation mode, heat dissipation and integrated package design of solid-state lighting devices are discussed, and the development trend of heat dissipation technology of solid state lighting devices are prospected.
