Description

LED封装模块
技术领域
本发明涉及半导体照明技术,尤其涉及一种LED封装模块。
背景技术
LED灯具有寿命长、省电力的特点,越来越广泛地应用于照明领域。
传统的LED封装模块,一般将LED芯片设置在基板上,然后在基板上设置绝缘层和电路层。如中国专利文献CN101684899A于2010年3月11日公开的照明用LED封装,包括基板和LED芯片,该基板具有固晶面和布线面,其特征在于:所述布线面具有线路部分和绝缘部分,所述线路部分构成所述基板上的电路,所述线路部分与所述绝缘部分构成所述布线面的表层;所述LED芯片设置于所述固晶面;该LED封装模块还包括换能层,所述换能层设置于所述布线面并覆盖于所述线路部分和绝缘部分之外;所述换能层由导热绝缘胶与纳米TiO2和纳米SnO2的混合物组成。本发明提供一种正面散热效率高的LED封装模块。
现有技术的缺陷是显而易见的,一方面大量使用基板,其结构复杂,成本高,使后顺灯具设计受到制约;另一方面,基于基板的封装维修复杂,需要专利的空间环境和专业人员,所以当出现故障时,往往需要整个基板报废,造成浪费。
发明内容
本发明的目的在于克服上述现有技术的不足之处而提供一种结构简洁的LED封装模块。
本发明的目的可以通过以下技术方案实现:
一种LED封装模块,包括LED芯片,其特征在于:还包括铜柱,铜柱穿设于胶壳,LED芯片设置于铜柱上表面的端部,铜柱下端面从胶壳的下表面露出,LED芯片从胶壳的上表面露出,胶壳内夹设电极,电极也从胶壳的上表面露出,LED芯片与电极之间通过金线连接。
LED封装模块,其特征在于:所述铜柱具有台阶,所述台阶将铜柱界定为大端和小端,LED芯片设置与铜柱的小端。
LED封装模块,其特征在于:所述胶壳上面具有柱状沉孔,沉孔具有水平的底部,所述的LED芯片及电极从胶壳上表面露出是指LED芯片及电极从沉孔的底部露出。
LED封装模块,其特征在于:所述电极仅仅连接金线的部位从所述胶壳上表面露出。
LED封装模块,其特征在于:所述电极水平夹设于胶壳内。
LED封装模块,其特征在于:所述电极延伸至所述胶壳之外,又构成另外LED封装模块的电极,所述延伸部分构成LED封装模块之间的支架。
LED封装模块,其特征在于:LED芯片出光面通过喷涂的方式涂设以无影胶为溶剂的荧光粉。
一种LED封装模块阵列,其特征在于,具有前述任一项技术方案所述的LED封装模块及支架。
本发明的LED封装模块,铜柱穿设于胶壳,LED芯片设置于铜柱上表面的端部,铜柱下端面从胶壳的下表面露出,在不降低散热效果的前提下,以铜柱取代了基板,并且不再需要设置专门的绝缘和电路,与现有技术相比,结构简洁。
