Abstract

本发明提供一种射灯，包括一内设有发光元件且一端开口的灯体以及一罩在该灯体开口端的菲涅尔透镜，该菲涅尔透镜是由若干呈环状的透镜体组成的罩体。本发明射灯通过在该灯体上罩一具多个透镜体的菲涅尔透镜，由于菲涅尔透镜具有聚光的特性，而使灯体内发光元件发出的光线通过该菲涅尔透镜时会产生聚光，从而使得射出的光线更密集，光强度、亮度更大，而可照射得更远。

Description

射灯
技术领域
本发明涉及一种灯具，特别涉及一种采用了菲涅尔透镜进行聚光的射灯。
背景技术
在日常生活中，尤其是在晚间，人们大都采用电灯来提供照明或装饰，如家庭用的白炽灯、大街上用的射灯、霓虹灯等。
人们常见的射灯大多包括一灯体及一透光罩，灯体内装设有发光元件，其发出的光线穿过透光罩向外射出，从而照亮电灯周围的空间，如果电压稳定，灯体每时每刻发出的光线都是相同的，且光线透过透光罩后会向着四面八方散射。通常，射灯的透光罩只是起到对灯体内的发光元件的保护作用，而不具有聚光效果，穿过透光罩射出的光线在射向远处时，衰减得很快，而现有的射灯为提高光线的强度、亮度只能依靠更换更大功率的发光元件，提高发光强度来获得较大的强度、亮度，而这也必然导致发光元件发热量大，损耗大，发光元件使用寿命较短。
发明内容
本发明所要解决的技术问题是:提供一种射灯，其具有非常好的聚光性能，光线可照射得更远。
为解决上述技术问题，本发明采用如下技术方案:本发明提供一种射灯，包括一内设有发光元件且一端开口的灯体以及一罩在该灯体开口端的菲涅尔透镜，该菲涅尔透镜是由若干呈环状的透镜体组成的罩体。
本发明的有益效果是:本发明射灯，通过在该灯体上罩一具多个透镜体的菲涅尔透镜，由于菲涅尔透镜具有聚光的特性，使灯体内发光元件发出的光线通过该菲涅尔透镜时会产生聚光，从而使得射出的光线更密集，光强度、亮度更大，而可照射得更远。
下面结合附图对本发明作进一步的详细描述。
附图说明
图1 是本发明菲射灯的分解示意图。
图2 是本发明射灯的菲涅尔透镜的立体图。
图3 是本发明射灯的组装示意图。
具体实施方式
如图1 至图3 所示，本发明射灯的较佳实施方式包括一灯体10 及一罩在该灯体10 上的菲涅尔透镜40 。
所述灯体10 呈一端开口的壳状，其内部装设有一发光件，如各种白炽灯、钠灯、LED 灯等。
所述菲涅尔透镜40 大致呈半圆球体的罩体，其一端具有一开口端42 ，该开口端42 处还形成一固定边44。该菲涅尔透镜40 是由若干有聚光作用的环形透镜体组合形成，如其中一透镜体46。
该菲涅尔透镜40 可固定到该灯体10 的开口端而构成一封闭空间。固定方式可以有多种，如:通过在菲涅尔透镜40 的固定边44 外侧设有一胶粘层而粘固在该灯体10 上:或者在灯体10 的内侧设内螺纹，并在该菲涅尔透镜40 的固定边44 的外侧设外螺纹，通过内、外螺纹的相互配合可将该菲涅尔透镜40 固定至该灯体10 。
该射灯工作时，发光元件发出的光线在穿过该菲涅尔透镜40 时，会由菲涅尔透镜40 进行聚光，从而在该菲涅尔透镜40 外侧形成聚光效果，使得发出的光线强度、亮度更大，而能照射得更远。
