Description

改进的LED灯照具
技术领域
本实用新型涉及一种LED灯，具体是一种适用于大功率、散热性能良好的改进的LED灯照具。
背景技术
目前广泛使用的的LED灯照具一般仅包括电源套筒和用以承载LED灯并起散热用途的铝基板，通过铝基板和套筒将LED灯发出的热量发散，主要是利用空气散热。而这样的方式散热效果并不理想，不能有效的发散LED灯照具本身的高温，从而使得元器件的寿命因高温而缩短，并且局限了大功率LED灯的开发使用。
发明内容
为了克服现有技术的缺陷，提供一种能延长元器件寿命、提高安全系数并能实现更大功率的具有散热器的LED灯筒。
为了实现上述目的，本实用新型采用了如下技术方案：
改进的LED灯照具，包括电源套筒1、散热器2、LED灯3和灯座4，LED灯3安装在电源套筒1内，散热器2环设在电源套筒1外表，灯座4设在散热器2的顶部，灯座4上可以安装任何通用的卡口或螺口灯头，如MR16、E27、PAR系列等。
散热器2包括复数个散热鳍片21，散热鳍片21呈放射状等间距排列成环状罩杯，扣设在电源套筒1外表。相邻的散热鳍片21，构成一个曲状的空气导流槽，外部冷空气以顺流方式快速引入空气导流槽而形成承风面，进而迫使将外部冷空气平均分散导入至各散热鳍片21之间，作快速导引散热，从而将热量作快速扩散排放。
电源套筒1下方设有凹面反光镜5，因为有特殊结构的散热器2，由凹面反光镜5的聚光效果产生的热量能得到及时的散发。
还可以沿投射方向在凹面反光镜5上叠设一透镜6，以丰富灯照投射的效果。
作为上述技术方案的改进，散热器2的底部开口处制有与凹面反光镜5的边沿匹配的倒角斜面22。
作为上述技术方案的进一步改进，设有镜框7，倒角斜面22边沿设有与镜框7匹配的凹槽23，镜框7嵌设在凹槽23内以固定凹面反光镜5和透镜6。镜框23设有内螺纹，凹面反光镜5和透镜6的位置通过与镜框23的内螺纹的配合来调节并固定。
附图说明
图1是本实用新型的使用状态示意图。
图2是本实用新型的投射端示意图。
图3是图2的A-A剖面示意图。
图4是本实用新型散热器的结构示意图。
图5是本实用新型的装配关系示意图。
具体实施方式
下面结合说明书附图和具体实施方式对本实用新型做进一步的说明，但本实用新型所保护的范围并不局限于此。
如图1、图2、图3、图4和图5所示，改进的LED灯照具，包括电源套筒1、散热器2、LED灯3和灯座4，LED灯3安装在电源套筒1内，散热器2环设在电源套筒1外表，灯座4设在散热器2的顶部，灯座4上可以安装任何通用的卡口或螺口灯头，如MR16、E27、PAR系列等。
散热器2包括复数个散热鳍片21，散热鳍片21呈放射状等间距排列成环状罩杯，扣设在电源套筒1外表。电源套筒1下方设有凹面反光镜5，因为有特殊结构的散热器2，还沿投射方向在凹面反光镜5上叠设一透镜6。散热器2的底部开口处制有与凹面反光镜5的边沿匹配的倒角斜面22，还设有镜框7，倒角斜面22边沿设有与镜框7匹配的凹槽23，镜框7嵌设在凹槽23内以固定凹面反光镜5和透镜6。镜框23设有内螺纹，凹面反光镜5和透镜6的位置通过与镜框23的内螺纹的配合来调节并固定。
本实用新型具有如下的有益效果：
散热效果理想，能有效的发散LED灯照具本身的高温，还能使聚光效果产生的热量能得到及时的散发，既丰富了灯照投射的效果又保障了元器件的使用寿命，使得大功率LED灯照具的开发使用得以实现。
