一种散热型投光灯

Abstract

本申请涉及一种散热型投光灯，包括依次设置的发光组件、导热组件和散热组件；发光组件包括安装板和多个阵列分布在安装板上的灯珠；导热组件包括导热板、多个第一导热柱和多个第二导热柱，导热板连接在安装板背向灯珠的一面，多个第一导热柱和多个第二导热柱阵列分布在导热板背向安装板的一侧，多个第二导热柱均匀分布在导热板的中部，并与第一导热柱间隔设置；散热组件连接在多个第一导热柱和第二导热柱上。本申请通过设置导热板、第一导热柱和第二导热柱，能够高效地将来自灯珠和安装板的热量传递至散热组件，从而实现散热，通过将第二导热柱设置在导热板中部，有效地针对更容易集中热量的部分进行散热，保证内部不易因为温度过高而损坏。
