一种LED一体化筒灯照明装置
技术领域
本发明涉及LED筒灯技术领域，具体为一种LED一体化筒灯照明装置。
背景技术
LED作为第四代照明光源，具有显著的节能和寿命优势。随着社会的发展，日常生活中的照明能耗问题日益突出，因此，具有显著节能优势的LED电源模组具越来越受人们的青睐。LED筒灯是应用新型LED照明光源在传统筒灯基础上改良开发的产品，与传统筒灯对比具有节能、低碳、长寿、显色性好、响应速度快的优点。LED筒灯的设计更加的美观轻巧，安装时能达到保持建筑装饰的整体统一与完美，不破坏灯具的设置，光源隐藏建筑装饰内部，光源不外露，无眩光，人的视觉效果柔和、均匀。LED筒灯被广泛用与楼道、办公室、学校、医院等场所。
然而，现有一体式筒灯都需要靠螺丝和压线扣固定线材从而达到线材防退防拉结构要求，细小部件较多，组合安装操作麻烦，降低了生产效率；另外，传统的LED筒灯都会配置体积较大的散热器，通过散热器为筒灯内部的LED光源、驱动电源散热，结构组成复杂，制作生产成本较高。
发明内容
本发明的目的在于提供一种结构设计简单，制作成本低、能够有效限制线材移动，散热效果好，有效防尘的LED一体化筒灯照明装置，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种LED一体化筒灯照明装置，包括扩散罩、LED光源组件、散热器、电源驱动组件和筒灯壳体，所述筒灯壳体包括中空腔体、形成于中空腔体两端的顶部开口和底部开口，所述散热器为金属罩体，金属罩体安装在中空腔体内，所述电源驱动组件设置在金属罩体上方的中空腔体内，所述金属罩体的顶部端面上固定设置有至少两个线材卡座，线材卡座上设置有线材卡槽，所述金属罩体的底部端面贴合固定有LED光源组件，金属罩体中心设置有用于连接LED光源组件和电源驱动组件的线材穿过的中心孔，所述LED光源组件包括光源基板盘以及光源基板盘上环绕布置的多个LED灯珠，所述扩散罩安装设置在筒灯壳体的底部开口上，扩散罩顶部端面与金属罩体的底端罩边接触连接。
