Description

发光二极管反射镜 技术领域
本发明涉及照明设备， 具体涉及一种用在照明设备中的反射镜。
背景技术
通常所见的照明设备， 如电筒， 一般均包括灯罩和与灯罩螺纹连接的 壳体， 壳体内装有电池和开关等， 壳体前端固定连接一光源， 而在灯罩里 装设反光镜， 如图 1 所示， 反光镜 21 中间开设一孔洞， 连接在壳体前端 23上的光源 22穿过此孔洞而伸入灯罩内。此时， 光源 22发出的光线经反 光镜 21反射后， 光度在光区中心有所增强， 而光区边缘光线较弱， 使亮点 区域较小； 当光源选用发光二极管时， 比较省电， 但在现有结构下， 从二 极管发出的较弱光线虽经反光镜增强， 但光度仍然较暗， 不能达到使用要 求； 而当光源选用白炽灯泡时， 光度较强， 但耗电量大， 使用时需要经常 更换电池， 非常不经济。
发明内容 、
本发明的目的在于提供一种全新设计的、 既可省电又能保证光线强度 的发光二极管反射镜， 其可以大幅增强发光二极管发出的光线强度， 用于 照明设备中。
为实现上述目的， 采取如下技术方案：
本发明提供的发光二极管反射镜， 装设于照明设备中， 包括一反射镜， 一前盖以及一发光二极管， 所迷反射镜为一整体弧面镜， 所迷前盖搭盖于 反射镜开弧端， 而所述发光二极管装设于前盖朝向反射镜一面的中心。
上述发光二极管反射镜中， 所述发光二极管的电线从所述前盖盖面中 央向边缘引出， 并依美观使各电线均匀分布。
上迷发光二极管反射镜中，.所述反射镜弧面抛物线方程为 y2=4Ax， 其 中， A为发光二极管与所述反射镜弧底距离。
上述发光二极管反射镜中， 所述反射镜弧面端向端口延伸面为平面。 上述发光二极管反射镜中， 所述前盖选用透明材料制成。
上述发光二极管反射镜中， 所述反射镜外设罩体， 用以与所迷照明设 备连接。 依据上述技术方案， 本发明提供的发光二极管反射镜提出了一种全新 的概念， 与传统的反光镜设计刚好相反， 发光二极管安设在与镜面相对的 前盖上， 而不是如常规安装在反光镜的孔洞内， 这样， 发光二极管发出的 光线可以经反射镜反射后平行射出， 使光度增强， 即便是二极管发出的光 线， 亮度也可以增强很多， 但同时可以保留使用二极管省电的好处； 另夕卜， 本发明的没计， 反射镜本身为一体镜面， 不必开设孔洞， 可以简化制镜工 序， 节省制作费用。
附图概述
图 1显示的传统结构电筒中反光镜与光源的位置关系；
图 2为本发明中的反射镜与发光二极管结构关系图；
图 3为的图 2的正视图。
本发明的最佳实施方式
以下结合附图和具体实施例详述本发明：
参见图 2， 实施例提供的发光二极管反射镜， 包括一反射镜 11 , 一前 盖 13以及一发光二极管 12。反射镜 11为一弧面镜， 其镜面上没有像传统 反光镜那样开设孔洞， 整个镜面自然成弧， 弧面抛物线方程为 y2=4Ax， 其 中， A为发光二极管与所迷反射镜 11弧底距离。在本实施例中， 反射镜 11 弧面端向端口延伸面为平面。反射镜 11 开弧端可以加厚， 并设计一台沿 15， 前盖 13搭盖于反射镜 11开弧端的台沿上。具体实施中， 前盖 13与 反射镜 11之间可以采用多种连接方式， 如插接或卡接等等， 本实施例中不 一一列举。
继续参见图 2和图 3， 发光二极管 12装设于前盖 13朝向反射镜 11 的一面中心， 发光二极管 12的管座与前盖 13紧固连接， 如粘连， 发光二 极管 12管体可以与管座活动连接， 以利于更换管体； 发光二极管 12的电 线 14沿著前盖 13的盖面由中央向边缘引出反射镜 11，接入照明设备壳体 的电路中， 为了美观， 电线 14最好在前盖 13盖面上均匀分布， 参见图 3， 在前盖 13盖面上一般均布三条线， 一方面视觉上比较舒服， 另一方面， 三 条线对光线的射出不致有过多影响。
用于制作本发明前盖 13 的材料应为透明材质， 可以为玻璃或有机玻 璃等材质。 本发明公开的是一种发光二极管反射镜， 它作为配件， 可以用于电筒 中， 也可以用在其它照明设备中， 如台灯、 吸顶灯等， 在此不一一列举。 发光二极管反射镜用于电筒时，可以直接将反射镜 11弧底朝向电筒手持部 分， 用一灯罩压固本发明发光二极管反射镜并连接电筒手持部分。在装入 不同照明设备时， 可根据不同的安装要求增设不同结构的罩体， 以实现与 照明设备的连接， 在此不——列举。
工业应用性
本发明的发光二极管安设在与镜面相对的前盖上， 而不是如常规安装 在反光镜的孔洞内， 这样， 发光二极管发出的光线可以经反射镜反射后平 行射出， 使光度增强， 即便是二极管发出的光线， 亮度也可以增强很多， 但同时可以保留使用二极管省电的好处； 另外， 本发明的设计， 反射镜本 身为一体镜面， 不必开设孔洞， 可以简化制镜工序， 节省制作费用。本发 明产品适于工业上的应用。
