Description

一种LED灯 技术领域
本发明涉及一种LED灯具，尤指一种LED导光结构。
背景技术
发光二极管(Light Emitting Diode，LED)由于具有低耗能、省电、使 用寿命长、体积小、反应快等特点，故已逐渐取代传统灯泡而应用各种发 光装置中。
技术问题
由于LED为点状光源，故实际应用时通常是将多个LED 作为一个发光模块，再将该发光模块设置在具有反射面的灯座内，借以汇集LED所发出的光，并增加LED的照射面积。
此外，也有使用单一LED作为光源的发光模块，该LED所发出的光 经过反射后，可经由一光纤管道而予以导出，从而进行照明使用；但，此结构方式实际施行使用时却存有下列缺点：由于该LED所发出的光是经过反射后再通过光纤予以导出，因该LED的光会受限于折射面而产生有限的折射次数，倘若折射面成型有锐角时，光在折射的过程中极易产生损耗，造成该LED光源经由光纤导出后的亮度不足，故无法成为良好的发光模块。
 技术解决方案
一种LED导光结构，包括：
一反射座体，具有一中空腔室，所述中空腔室的壁面系成型为无锐角状；
至少一LED光源模块，固定在所述反射座体上，所述LED光源模块包含位于所述中空腔室内的LED；
以及一光纤管，所述光纤管的一端设置在所述中空腔室内，另一端延伸在所述反射座体外。
较佳地，所述反射座体由二半圆壳体所组成，所述反射座体的外型系呈球状。
较佳地，所述反射座体成型有一安装平台，所述安装平台设有一入光 口，所述LED光源模块装设在所述安装平台上，且所述LED经由所述入 光口而突伸至该中空腔室内。
较佳地，所述反射座体设有一出光口，所述光纤管系穿设在所述出光口中。
较佳地，所述反射座体设有复数个所述出光口，各所述出光口系开设在所述入光口的相对侧。
较佳地，所述LED光源模块的数量为复数，且所述反射座体对应成 型有复数个所述安装平台，每一所述安装平台分别设有所述一入光口，各所述LED光源模块系分别装设在所述安装平台上，且所述LED经由所述 入光口而突伸至该中空腔室内。
较佳地，所述反射座体对应设有复数个所述出光口，各所述出光口分 别对应开设在所述入光口的相对侧。
较佳地，所述反射座体的外型系呈角柱状。
较佳地，所述中空腔室的壁面镀有高反射率材质，所述中空腔室的壁面成型为弧面状。
较佳地，包括热导接所述LED光源模块的一散热体，所述散热体包 含有一均温板及一组散热片，所述均温板系贴接所述LED光源模块，所述散热片系设置在所述均温板上。
较佳地，所述光纤管的一端结合有一透镜。
有益效果
提供一种LED导光结构，以增加光线的反射次数，并减少光在折射的过程中产生损耗，以作为良好的照明灯具。
本发明的另一效果，在于提供一种LED导光结构，可依所需调整照明亮度，且具有易于管理及维修的优点。

该光纤管40系穿设在该出光口13中，该光纤管40的一端设置在该 中空腔室100内，另一端结合有一透镜41而延伸在该反射座体10外。
请续参照第四图，系为本发明LED导光结构的使用示意图；使用本发明的LED导光结构时，该LED光源模块20的LED21所发出的光会经由该中空腔室100的壁面而反射至该光纤管40，再透过该光纤管40的导 光而进行照明，由于该中空腔室100的壁面成型为无锐角状，故光线可在该中空腔室100进行多次的反射，且较不产生光损耗，并可将该LED光 源模块20所产生的光大部分反射至该光纤管40，另透过该光纤管40的透 镜而增加照射面积，以作为照明之用。
