Description
技术领域 technical field

背景技术 Background technique
随着 LED灯应用范围越来越广，大功率高亮度LED芯片应运而生；近年来随着大功率高亮度LED芯片的研制成功及其反光效率的不断提高，越来越多的大功率高亮度LED开始进入照明领域。 As the application range of LED lights becomes wider and wider, high-power and high-brightness LED chips emerge as the times require; in recent years, with the successful development of high-power and high-brightness LED chips and the continuous improvement of their reflection efficiency, more and more high-power Brightness LEDs are beginning to enter the lighting field.
对于LED灯具而言，为保证其散热效果，现有的LED灯具普遍都配置有铝合金散热器或者导热塑料散热器；其中，对于铝合金散热器而言，由于铝合金散热器的比重较大，铝合金散热器越重，其安装难度越大且运输成本越高；另外，铝合金散热器能够导电，在LED灯具设计过程中，必须要考虑绝缘设计，这就增加了整个LED灯具的结构复杂程度且成本增高。 For LED lamps, in order to ensure their heat dissipation effect, existing LED lamps are generally equipped with aluminum alloy radiators or heat-conducting plastic radiators; among them, for aluminum alloy radiators, due to the large proportion of aluminum alloy radiators , the heavier the aluminum alloy radiator, the more difficult it is to install and the higher the transportation cost; in addition, the aluminum alloy radiator can conduct electricity, so in the design process of LED lamps, insulation design must be considered, which increases the structure of the entire LED lamp Complexity and cost increase.
对于导热塑料散热器而言，其虽然具备质轻且绝缘的特质，但是导热系数较铝合金的导热系数低很多，对于某些大功率且高散热要求的LED灯具而言，导热塑料散热器很难适用。 For thermally conductive plastic radiators, although they have the characteristics of light weight and insulation, their thermal conductivity is much lower than that of aluminum alloys. For some LED lamps with high power and high heat dissipation requirements, thermally conductive plastic radiators are very good. Difficult to apply.
