Description

集光体 技术领域
本发明是指一种集光体，尤其是指一种上方具有采集光线的集光突部，下方具有菲涅耳透镜的集光体。
背景技术
如图1所示，一穿贯温室植物工场屋顶2的导光管11，该导光管11内壁设有反射膜111。一组设于导光管11下端的出光单元12，出光单元12包含有：一防眩光亚克力板121及一扩散光亚克力板122。一组设于该导光管11上方的集光罩14，集光罩14为中空半球形，是由亚克力材质一体成型。
而该导光管11在使用时，集光罩14是先让光线A透入导光管11，导光管11利用反射膜111将光线A折射至防眩光亚克力板121及扩散光亚克力板122处，而导光管11再利用防眩光亚克力板121及扩散光亚克力板122将光线A均匀散射至该温室植物工场屋顶2下方。
但是，集光罩14制作时，是先用高价格的模具压迫亚克力板弯曲成型为中空半球形的集光罩14，加上导光管11与防眩光亚克力板121及一扩散光亚克力板122的多重组接，加重了整体的组装成本，致此集光罩14与导光管11衔接配合并不符合现下高物价通膨的社会。另外，光线A是一折射后会逐渐消耗的能量，因此光线A通过集光罩14会少量衰竭，再经过反射膜111折射及通过防眩光亚克力板121及扩散光亚克力板122朝下散射，其光线A也就不足原有的40％左右。
因此，可知高成本制作的弧形集光罩14与导光管11的设置除了会消耗光线A使用能量外，也不再符合高物价通膨及高人力成本的现下社会，因此，集光罩14与导光管11已经成为一必须摒弃的事物。
发明内容
鉴于以上所述，得知已知集光罩与导光管设置有制作成本过高问题及消耗光线使用率的缺失，因此，促使本案发明人朝向提升光线使用率与降低整体成本的方向研发，并经由本案发明人多方思考，遂而思及，据以一板体制做的集光体为最佳。
本发明是指一种集光体，其中，该集光体本身为一透光的板体，而该集光体上方凸出有密集分布的多个集光突部，每一个该集光突部上方至少曲设有一增加采集光线面积及角度的集光弧面：而该集光体下方凸出有密集分布的多个菲涅耳透镜，每一个该菲涅耳透镜下方至少曲设有一出光弧面。
而后，该出光弧面周围环设一圈至五圈的出光弧环。该集光突部设有一集光锥升柱，该集光锥升柱侧缘环设有一增加上采集光线面积的集光锥弧面，且该集光锥升柱顶缘具有该集光弧面。
本发明的目的在于：该集光体是以上方具有采集光线的集光突部，且光线通过集光突部偏光后由下方的菲涅耳透镜汇集射出，具有增加光线使用率的效益。

具体实施方式
为使对本发明有更进一步的了解，现以下列实施例进行说明。
本发明提供了一种集光体1，其中，该集光体1本身为一透光的板体，而该集光体1上方凸出有密集分布的多个集光突部11，每一个该集光突部11上方至少曲设有一增加采集光线A面积及角度的集光弧面111；而该集光体1下方凸出有密集分布的多个菲涅耳透镜12，每一个该菲涅耳透镜12下方至少曲设有一出光弧面121，如：图2、3所示。
该集光体1是以该集光突部11增加对该光线A多角度收集，且利用该集光突部11的集光弧面111对该光线A在该集光体1内偏光处理，偏光的该光线A再通过该菲涅耳透镜12的出光弧面121大量直导朝下透出该集光体1，该集光体1即是用此本身极薄的板体透光，并同时达成光线A可多角度收集、穿导后大量朝下直射光线A的物体。同时，集光弧面111对该光线A中所含的热能B也有适度性折射的效益，如：图2、3所示。
本发明为增加光线A朝下大量直射数量，因此在该出光弧面121周围又环设一圈至五圈的出光弧环122。该集光突部11为了增加对光线A收集范围，因此在该集光体1上方设有一集光锥升柱112，该集光锥升柱112侧缘环设有一增加上采集光线A面积的集光锥弧面113，且该集 光锥升柱112顶缘具有该集光弧面111，而该集光锥升柱112的该集光锥弧面113恰好可配合该集光弧面111有效扩大收集角度与收集面积。借此，本身为一体积小、相应成本也极低的透光板体制做的该集光体1，该集光体1适用于种植温室、校园、工厂、办公室、商家与一般室内等等，由此可知，该集光体1是用于采集屋外光线A的最佳选择(如：图4所示；另外：种植温室、校园、工厂、办公室、商家与一般室内在此未绘出及标号)。
经由以上叙述可知本发明是以：该集光体1本身为一体积小、相应成本也极低的透光板体，且该集光体1是以上方具有采集光线A的该集光突部11，该集光突部11先以该集光弧面111多角度收集光线A，光线A同时由集光突部11偏光处理，再由下方的菲涅耳透镜12汇集朝下直射出。
本发明的技术内容及技术特点已揭示如上，然而熟悉本项技术的人士仍可能基于本发明的揭示而作各种不背离本案发明精神的替换及修饰。因此，本发明的保护范围应不限于实施例所揭示的内容，而应包括各种不背离本发明的替换及修饰，并为发明申请专利范围所涵盖。
