Description

本发明涉及一光线辐射器件，具体地说，涉及一用以有效地从一光导体光缆射出的光线能分散成一直接的光线成分和一间接的光线成分以便更加有效地用于培育植物以及当利用传输通过光导体光缆的光线能来激活光合作用时利用该种光线。
为了有效地培育植物，需提供以数量恰当的营养物质、光线、二氧化碳、水和湿度等。然而欲以正确的量来提供这些事物是困难的。此外，植物的培育还需要土地作为基础以用作被培育的植物的母体。
然而在城市地区如具百万人口的大城市中，欲获得用以培育植物的空间极为不易。特别是为了对植物进行培育的需要而保证土地处在阳光中是极难的。为了解决这些问题，本申请人过去曾提出过利用透镜之类聚焦太阳光，以将光线导入一光导体光缆，并进一步将该光线通过光导体光缆导向到一安装于任意的、所需地方的植物培育器件上以用作向植物供应太阳光能的目的。本申请人又曾提出过另一种植物培育器件，在该器件中除太阳光外还利用了人造光按上面叙述的方法进行收集。（例如，参照美国专利第4，653，233号）
为了有效地培育植物需要直接的太阳光和间接的太阳光。用传统方法和先有方法能有效地在植物上照射那些直接的太阳光和间接的太阳光的光源器件未曾被提出过。
本发明的目的在于提供一能有效地在植物上照射直接的太阳光和间接的太阳光的光线辐射器件。
本发明的另一个目的在于提供一光线辐射器件，直接的光线和间接的光线之比可任意地选择至一所需值以便向植物供应两种类型的光线，并从而使植物能更加有效地被培育起来。
本发明的上述特点和优点，从下文详细的叙述中结合附图而变为明显可见。
图1为说明本发明的一个实施例的一个结构图;
图2为说明示于图1中光漫射和反射类型液晶片的一个截面图。
图1为说明按照本发明的光线辐射器的一个实施例的结构图。在图1中，一光导体光缆1，光能是通过该光导体光缆1传输;一具一孔的上部片2，通过该孔将该光导体光缆1的发光端部1a塞入在该上部片的大约中心部分位置上;一光漫射和反射类型液晶片3（一下部片）如此设置以使之与光导体光缆1的发光端部1a对置，用以整体地安装该上部片2和下部片3的一构架体4;及能在标以A或B的箭头所示的方向上在上部片2与下部片3之间的构架体上运动的、并具有一中央部分能让光线穿过的中间片5。中间片5的周边部分5a是由一镜片或一光漫射和反射液晶片构成的。
图2为说明光漫射和反射液晶片3的一个实施例的一个横截面图。该液晶片3由一上部透明电极片3a、一下部透明电极片3b和一气密地密封在电极片3a和3b之间的光漫射和反射液晶3c组成的。当未在电极3a和3b两端施加电压时，该液晶3c是透明的。相反，例如当在电极3a和3b两端施加以10伏特电压时，该液晶变为一光漫射和反射片。
在图2中，6表示用以施加电压到电极3a和3b上的引线，而7为一电源器件。在该电源器7中安装以一用以接通或断开电源电压的开关，或安装以一用以连续地改变该电源电压的可变电阻或用以分段每段相同地改变该电源电压的步进开关。
通过旋动开关在“开”或“关”的位置，该光漫射和反射液晶片3变为一光漫射和反射片或一透明片，并因而可交替地将直接的光线或间接的光线聚焦在一任意所需的地方上。另外，也可能通过利用可调电位器（一可变电阻）连续地改变该直接的光线成分和间接的光线成分之比，否则可通过利用步进开关分段地改变上述的两个成分之比。
中间片5的中央部分5b为中空并由透明片构成的。从该光导体光缆1辐射的光线之中，只有穿过该中空部分或透明部分5b的光线能达到设置在该器件的底部的光漫射和反射类型液晶片3上。在那个场合下，当光线直接穿过该下部液晶片3时，该光线作为直接的光线而照射到一所需的地方，而当将电压施加在下部液晶片3时，依赖于施加于其上的电压的量值而将该光线划分成直接的光线和间接的光线，且该光线被辐射到一所需的地方。在中间片5的周边部分5a是由一反射片的形式而制成的情况下，当将中间片5沿箭头A所示的方向运动时，该穿过下部片3的直接的光线成分减少，而反射到反射片部分5a的光线作为间接的光线被辐射出去。在那个时候，为了有效地利用反射到该反射片部分5a上的光线作为间接的光线而被辐射出去，该上部片2的下部表面2a被制成一光反射表面的状态，而构架体4是由半透明物质制成的。在这样的结构中，反射到该光反射表面5a和2a的光线有效地被那些半透明体所散射，因此能将该间接的光线有效地辐射出去。
此外，在该环状中间片5的周边部分5a是由一光漫射和反射液晶片制成时，该液晶片部分5a如联系图2中所述变为透明体或反射体，并从而使该光线能被划分成直接的光线和间接的光线并更加有效地被辐射出去。
另外，在图2中8为一光传感器，穿过下部光漫射和反射液晶片3的光线的强度由光传感器8所探测。施加到下部光漫射和反射类型液晶片3的电压是按照由光传感器产生的探测信号而变化。在这种方法下，有可能用一所需的光线强度来照射到植物上。
由前面的叙述可见，按照本发明，直接的光线和间接的光线之比可任意地选择成一所需的值以供应两种类型光线到植物上，并从而可使植物更加有效地被培育。
