Abstract

本实用新型公开了一种LED球灯泡,包括灯头、LED芯片、灯泡体,LED芯片封装在铝基板上,灯泡体为球形灯泡体。本实用新型结构合理,散热性能好,采用COB封装降低了系统热阻,可比传统方式降低LED工作温度5~10℃,可将外形制作成传统的白炽灯外形。

Description

LED球灯泡
技术领域:
本实用新型涉及一种LED灯。
背景技术:
现有的普通灯泡在发光效率、散热性能等方面存在不理想之处,普通的LED灯热阻较大,不能制成传统白炽灯的形状。
发明内容:
本实用新型的目的在于提供一种结构合理,工作性能好的LED球灯泡。
本实用新型的技术解决方案是:
一种LED球灯泡,包括灯头、LED芯片、灯泡体,其特征是:LED芯片封装在铝基板上,灯泡体为球形灯泡体。
所述LED芯片为COB封装形式,铝基板上设置多个放置LED芯片的凹坑,凹坑的边缘呈反光斜坡面形式。
铝基板上紧贴有配光用透镜。
铝基板底部设置散热片,在铝基板与散热片之间设置导热层。
铝基板直径为30mm,铝基板上设有15~25个凹坑。
本实用新型结构合理,散热性能好,采用COB封装降低了系统热阻,可比传统方式降低LED工作温度5~10℃;COB封装可灵活选择LED芯片,搭配不同规格的驱动电源,可将外形制作成传统的白炽灯外形。
附图说明:
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型一个实施例的结构示图。
具体实施方式:
一种LED球灯泡,包括灯头1、灯壳2、LED芯片3、灯泡体4,LED芯片封装在铝基板5上,灯泡体4为球形灯泡体。
所述LED芯片3为COB封装形式,铝基板上设置多个放置LED芯片的凹坑,凹坑的边缘呈反光斜坡面形式。铝基板底部设置散热片6,在铝基板与散热片之间设置导热硅脂层7。
铝基板直径为30mm,铝基板上设有15~25个凹坑。
铝基板上还可紧贴有配光用透镜。
