Description
技术领域
本发明涉及一种照明装置。
背景技术
作为一种新兴的光源,发光二极管凭借其发光效率高、体积小、重量轻、环保等优点,已被广泛地应用到当前的各个领域当中,有取代传统光源的趋势。
目前应用发光二极管的灯具的缺点是光源利用率不高,灯具发出的光经常会有一部分照射到不需照亮的区域,不仅耗费了大量电能,也使非照明区域产生光污染。
发明内容
有鉴于此,有必要提供一种光源利用率较高的照明装置及其组件。
一种透镜,其具有一入光面及一出光面,该透镜的出光面包括一连续分布的第一出光面及形成其上的若干个内凹的第二出光面,该第二出光面可使穿过的光线向第一出光面对应的区域偏射。
一种发光二极管模组,包括一发光二极管及与其搭配的透镜,该透镜具有一入光面及一出光面,发光二极管发出的光线从透镜入光面入射,该透镜的出光面包括一连续分布的第一出光面及形成其上的若干个内凹的第二出光面,该第二出光面可使穿过的光线向第一出光面对应的区域偏射。
一种照明装置,包括一发光二极管及与其搭配的透镜,该透镜具有一入光面及一出光面,发光二极管发出的光线从透镜入光面入射,该透镜的出光面包括一连续分布的第一出光面及形成其上的若干个内凹的第二出光面,该第二出光面可使穿过的光线向第一出光面对应的区域偏射。
与现有技术相比,本发明中透镜上内凹的第二出光面的设置,将原本不必要照射到非指定照明区域的光线调整到需要照明的区域,使光源的有效利用率大大提高。
下面参照附图,结合具体实施例对本发明作进一步的描述。
附图说明
图1是本发明一个实施例中的发光二极管模组的立体组装图。
图2是图1中发光二极管模组的倒置图,此时发光二极管模组的发光二极管被移去以方便观察。
图3是图1中发光二极管模组沿III-III线的截面图。
图4是图1中发光二极管模组沿IV-IV线的截面图。
图5是本发明的发光二极管模组经过软件测试形成的等照度分布图。
图6是本发明多个集成的发光二极管模组示意图。
图7是应用本发明的发光二极管模组的路灯使用状态示意图。
具体实施方式
如图1及3所示,本发明一个实施例中的发光二极管模组30包括一发光二极管10及一包封发光二极管10的透镜20。该发光二极管10包括一基座12、一黏接于基座12顶面的发光二极管芯片14及一固定于基座12上并密封住芯片14的透明封罩16。该封罩16大致呈半球形,发光二极管芯片14发出的光线经由该封罩射出。该发光二极管10具有一光轴A。
请一并参阅图4,该透镜20由光学性能佳的透明材料一体成型,如PMMA或PC等塑料,使整个发光二极管模组30的出光效率达到90%以上。该透镜20具有一出光面21,该出光面21包括一从中央向外围连续分布的第一出光面22及相对于第一出光面22向内凹陷形成的四第二出光面24。该透镜20的出光面21具有一光轴B,该光轴B与发光二极管10的光轴A重合(如图3)。该四第二出光面24等距间隔排布并关于光轴B对称,且远离出光面21中央及光轴B,使第一出光面22大致呈一十字形。每一第二出光面24为一向内凹陷的椭球面,该椭球面可使穿过的光偏向第一出光面22出射(如光线b),使发光二极管10发出的光线经由透镜20投射的区域大致呈一十字形。可以理解地,该第二出光面24也可是向内凹陷的其它曲面,例如,两个相交的平面,只要能使穿过的光偏向第一出光面22出射即可。
请一并参阅图2,该透镜20于底部中央向内开设有一圆形台阶状的定位槽26,并在定位槽26的中部进一步向内开设一半球形空穴28。该定位槽26用以收容发光二极管10的基座12。空穴28用以容置发光二极管10的封罩16,空穴28表面为一球面,该表面作为入光面,用于将自发光二极管10出射的光线折射入透镜20。该空穴28表面具有一光轴C,光轴C与光轴A、B重合。可以理解地,在其它实施例中,该空穴28表面也可是作为入光面的非球面。
图5为发光二极管模组30经过软件测试形成的等照度分布图,图中央示出一明显的十字形,说明发光二极管模组30出射的大部分光会聚至十字形区域内。
可以理解地,多个发光二极管模组30可集成在一板体40上(如图6),以增加被照区域的光强。
请同时参照图7,当将应用这种发光二极管模组30的路灯50安装在道路60交会口处时,透镜20的第一出光面22可将从此出射的光线会聚到道路60交会处(如图4中光线a),第二出光面24可使穿过的光线偏向道路60交会处出射(如图4中光线b),从而发光二极管10发出光线经过透镜20后在道路60的交会路口处形成一交会的光形70。
与现有技术相比,本发明中透镜20上内凹的第二出光面24的设置,将原本不必要照射到非指定照明区域的光线调整到需要照明的区域,使光源的有效利用率大大提高。
