Abstract

一种LED照明配光系统，包括第一反光面（1），设置在第一反光面（1）底部的LED发光体（2），及设置在第一反光面（1）内的、与第一反光面（1）相对设置的第二反光面（3）。由于通过第二反光面（3）能够将LED的直射光进行分配，从第一反光面（1）上反射射出，能够将较多的光线控制在有效的立体角内，产生所需的配光效果。

Description

说 明 书 一种 LED照明配光系统
技术领域
本发明涉及一种 LED照明配光系统。
背景技术
目前 LED照明灯具普遍釆用单个反光面进行配光。由于 LED发光体 出光具有方向性， 垂直于 LED发光体出光面的光线， 无法经由一个反 光面全部反射， 达到所需的配光效果。
发明内容
本发明要解决的技术问题是提供一种优化的 LED配光方案，控制 LED出光路径， 产生所需的配光效果。
为解决上述技术问题，本发明采用如下技术方案： 包括第一反光 面，及设置在第一反光面内的 LED发光体，及设置在第一反光面内的、 与第一反光面相对设置的第二反光面。 进一步地， 所述第二反光面位于 LED发光体出光方向上。
进一步地， 所述第一反光面和第二反光面均为曲面设置。
本发明的 LED照明配光系统， 由于通过第二反光面能够将 LED发光 体的直射光进行分配， 从第一反光面上反射射出， 能够将较多的光线 控制在有效的立体角内， 产生所需的配光效果。 附图说明
图 1为本发明 LED照明配光系统的示意图。
具体实施方式
本实施例中， 参照图 1所示， 该 LED照明配光系统， 包括第一反 光面 1， 及设置在第一反光面 1内部的 LED发光体 2， 及设置在第一 反光面 1内的、 与第一反光面 1相对设置的第二反光面 3。 能够将较 多的光线控制在有效的立体角内， 达到所需的配光效果。
其中，所述第二反光面 3位于 LED发光体 2的出光方向上。所述 第一反光面 1和第二反光面 3均为曲面（包含用较小平面构成的曲面） 设置， 可以将较多光线控制在有效立体角内， 达到所需的配光效果。 本发明的 LED照明配光系统，由于通过第二反光面能够将 LED的 直射光进行分配，从第一反光面上反射射出， 能够将较多的光线控制 在有效的立体角内， 达到所需的配光效果。
以上巳将本发明做一详细说明， 以上所述， 仅为本发明之较佳实施例 而巳， 当不能限定本发明实施范围， 即凡依本申请范围所作均等变化 与修饰， 皆应仍属本发明涵盖范围内。
