植物照明光源

Abstract

本申请属于灯具技术领域，具体提供一种植物照明光源，植物照明光源包括支架、发光组件和荧光胶，发光组件包括第一发光芯片和发光模块，第一发光芯片贴装于支架上，第一发光芯片发出的光能够激发荧光胶中的荧光粉，发光模块包括底座和第二发光芯片，底座设置于支架上，第二发光芯片设置于底座背向支架的一侧，第二发光芯片为垂直结构芯片，荧光胶设置于支架上并且覆盖发光组件。将不需要激发荧光粉的第二发光芯片选择为垂直结构芯片，相比于平面结构芯片，其发光强度更高，再通过在第二发光芯片与支架之间设置底座，能够将第二发光芯片垫高，减小覆盖于第二发光芯片上方的荧光胶的厚度，以便于其发出的光穿出荧光胶，从而能够提高出光亮度。
