Description

LED射灯 技术领域
本申请涉及发光二极管领域，尤其涉及一种LED射灯。
背景技术
发光二极管(Light Emitting Diode，LED)作为一种绿色环保的发光半导体，其因节能环保、光效高等特点，被广泛用于照明、显示等多个领域。
在照明时，采用LED光源的射灯其通常仅朝一个方向设置有透光开口，使射灯仅只能朝一个方向照射，形成集中的光束。当因场景需要对同一片区域采用不同颜色的光束进行照射时，通常需要排布两个或更多数量的射灯来达到这种色彩更替的效果，从而制造成本较高。
发明内容
本申请旨在至少在一定程度上解决上述技术问题之一。
本申请提供一种LED射灯，包括：LED光源，以及设置所述LED光源的基座，所述LED光源包括：具有至少两个延伸部的灯板以及设置于所述延伸部上的LED发光芯片，所述基座包括：安装基体以及至少两个从所述安装基体不同方向延伸出且具有透光开口的照射筒，每个所述延伸部设置于对应的一个所述照射筒中。
进一步地，所述基座具有两个所述照射筒，每个所述照射筒中心轴线在同一直线上或呈一定夹角。
进一步地，所述基座具有至少三个所述照射筒，相邻的每个所述照射筒中心轴线之间呈一定夹角。
进一步地，所述照射筒呈直筒状。
进一步地，所述照射筒内径沿光线照射方向逐渐变大。
进一步地，所述透光开口处设置有光学透镜。
进一步地，所述光学透镜为内部阶梯状分布且具有菲涅耳条纹的菲涅耳透镜。
进一步地，所述灯板上设置有用于控制所述LED发光芯片工作的控制器。
进一步地，所述基座通过旋转轴与一安装支架旋转式固定以更换所述照射筒进行照射。
本申请的有益效果是：
通过提供一种LED射灯，包括：LED光源，以及设置所述LED光源的基座，所述LED光 源包括：具有至少两个延伸部的灯板以及设置于所述延伸部上的LED发光芯片，所述基座包括：安装基体以及至少两个从所述安装基体不同方向延伸出且具有透光开口的照射筒，每个所述延伸部设置于对应的一个所述照射筒中。这样，采用同一LED射灯可以满足对需要照射的位置变换不同照射筒中的LED发光芯片进行照射的需求，从而提高LED射灯的应用灵活性。
