[0006] 利用这种安排,该网格能够被构造成产生一致形状的光的格子。该安排还有均勻 得多的光输出的优点,从而当与集成反射膜单元一起使用时,能够产生比目前可用的其他 光发射产品优得多的性能。
[0007] 按照本发明的第二方面,如上所述的光接收设备能够是太阳电池板的形式,该太 阳电池板包含许多在反射板下面的薄膜电池单元,而该场致发光聚合物网格能够被安排成 接收光并把光转变为电能,能够提供把电能传送到电池单元、并安排激励光传输通过透光 基片及从反射器板反射进入该场致发光聚合物的装置。

[0012] 在一种优选的结构中,该成形开孔是六角形。
[0013] 该反射板能够通过许多分开的部分而被提供,这些分开的部分位于场致发光聚合 物网格中的开孔内。
[0014] 各种部分最好被承载在背衬上,该背衬能够是基本上刚性的或柔性的,由此使该 板能够被卷起或弯曲,而利用这种安排,合适的材料是柔性的铝箔。
[0015] 这样,利用这些安排,该背衬能够有柔性的保护基片。 [0016] 在合适的结构中,该光发射和/或接收设备能够是平的三角形板形状。

具体实施方式
[0033] 图1画出通过光发射板1的结构,表明作为PLED(聚合物发光二极管)层2的一 层P-0LED,当它被施加电流时发射可以是任一需要颜色的光。在它之上是透明的导体3 (氧 化铟锡)和透明的透光基片4。设置有铝的背衬5,而当PLED被激活时,沿箭头6所指方向发射光。
[0034] 图2画出按照本发明的结构,该结构有PLED层7及适当的电连接。该结构由图2 中的参考数字7指出。该板把一些产生的光反射回去通过透光基片4,如箭头8所示。直线 通过透光基片4的发射光,如箭头9所示。
[0035] 该PLED 2的结构是网格形式的,如图3所示。该网格3被构造成产生具有一致形 状的光的格子。该结构具有的优点是,当与集成的反射膜层一起使用时,有均勻得多的光输 出,同时能够产生比目前可用的其他光发射产品更优的性能。
[0036] 网格能够具有许多种成形开孔中的任一种,例如椭圆形、三角形、矩形或多边形, 而在图3所示的优选结构中,开孔是六角形的并用参考数字10表示。这种配置是优选的, 因为对板上的PLED膜和反射器二者,它在全360°上都有一致的均衡。利用板的这种标准 形状,它能够按宽广的各种间距尺寸设定,供任何专门的应用使用。
[0037] 图4是反射板的分解视图,并用相同的参考数字表示前面图中的相同部分。该分 解视图示出反射层7如何由许多六角形板11构成,这些六角形板11被置于网格2的六角 形开孔10的下端中。
[0038] 如将从图4所看到的,板可以包括:上透光基片层4、氧化锌铟透光导电层3,该透 光导电层3用作阳极并有类似于该透光导电层3要与之对准的网格2的配置。六角形板11 形式的反射板被定位在开孔10中,整个板在那里被安装在充当阳极(+)的铝框架13上,该 框架与绝缘体14和充当阴极(_)的下铝框架15合并,整个框架被承载在铝背衬5上。
[0039] 如将从附图所看到的,板具有三角形的形状。
[0040] 重量轻的铝背衬5提供强度和耐用性,并可以是用于PLED板2的电压-VE的阴 极。该框架为一般的照明应用提供一硬背的(hard-backed)板。另外,为便于携带,该板也 可以通过使用柔性铝箔作为有保护性的柔性基片的基座、提供柔性的绝缘体14并替换基 座和框架13及15,制作成柔性的。由此,这种类型的柔性板能够卷起来并被运输到遥远的 地方,在那里它能够容易展开来使用。
[0041] 这种类型的反射器板由于其柔性而能够用作替代品,代替一些目前在照明中使用的灯,例如荧光的和放电的灯。由于它们能够更柔软且产生较少的热,能够代替一些LED。 这种产品还有的优点是,因为所有光发射器和反射器都在一块薄的板上,所以它实际上能 够制作成任何形状。诸如荧光管配件等单元能够被减少到一个单一的替代配件。此外,在反 射板之前,可以把不透明膜放置(图上没有画出)在该板的透光基片之前,使光从它漫射。 在用于街灯的户外发光体中,可以用做成碗形的PLED板代替反射器碗和放电灯,但由于从 碗的内表面产生的反射光更均勻和有更高效率,所以有更优异的性能。来自该板的光能够 被制造成发射比荧光(低压汞)更接近日光且使用更安全的光,而且它不产生危险的可见 光频率并且比任何其他光源更适合用于办公室,零售店或户内居住的照明。
[0042] 再者,新的板更环境友好和遵从新的WEEE(Waste Electronic &Electrical Engineering)法令(报废电子电气设备法令)。在伦敦,有多达3,000,000个街灯单元,其 中包含照明的标志和标柱、交通信令系统及标准的光放射系统,如果在板中使用本发明主 题的技术,则可节省大量的能量和极大地减少碳排放。灯维护服务的成本也将减少,因为该 产品的正常寿命,在天天都用时,超过10年。
[0043] 在寿命结束时,反射板能够安全地拆解和回收,而新的WEEE法令要求所有电气或电子产品制造商必须在其产品的寿命周期结束时负责回收他们的产品。现有的灯是机械制造的,是用汞和其他有害的化学物品制造的,从而要销毁它们是困难的。本发明的板解决了 这个问题,而且更清洁和更安全。
[0044] 图5到图8示出利用相同类型结构的光接收设备。该太阳能板组合了在图1到4 中示出的结构中使用的有机发光二极管技术和反射膜技术的型式。
[0045] 该结构产生电是通过略微改变PLED化学式而使光转换为电的。当与集成的反射 层组合时,它增加由PLED吸收的光,以产生更多的电能,且该板有附加的储存被转换能量 的能力,该被转换的能量用电池汇集在同一板上。
[0046] 图5画出类似于图1所示的结构,相同的参考数字用于表示类似的部分。但是,在 该结构中,PLED层20起接收光并把接收的光转换为电能的作用。光源(日光)以箭头21表不。
[0047] 图6画出通过板的截面,进入的光再次用箭头21表示,而倾斜进入的光用箭头22 表示。反射镜板7再次把光反射回去,落在PLED层20上。这样,该结构按图2所示方向的 相反方向工作。被置于反射镜板11下面的是薄膜电池23。
[0048] 图7是类似于图4的视图,但表示的是太阳能板并再次用相同的参考数字表示类 似的部分。薄膜电池的位置清楚地画在反射器板11下面,而刚性及柔性的结构可以是如上 面描述的。
[0049] 薄膜电池23的使用允许板不需要外置的可再充电电池。每一电池被直接连接到 周围的非常接近的PLED层,降低电路内的电阻。这样进一步增强整个板上电的均勻流动。
[0050] 不难看出,该板还是三角形的,所以它们能够被分割成约IOcm2到300cm2的三角 盒。然后,能够用铝横梁沿类似大小的单元的边缘连接每一单元。板能够作为多块板或单 块片段被制造,这些单块片段可以用边缘上的槽接合在一起(没有画出)。这样的板在图8 中示出,那里28块三角形板与框架25互连。
[0051] 按照本发明的新的板,性能优于现有的太阳电池板,可产生更多功率、更高的电压 输出和更好的冷却。利用这些结构的灵活性,它们能够用于广泛的各种应用。
[0052] 如有需要,双侧的单元片段能够被用于户外使用并进一步扩展太阳电池板单元的 效率。
[0053] 在图9所示的结构中,两套板被背靠背地使用。上面一套按照图6到8构造并用 作太阳电池板,而下面一套则由图2到4所示单元放在一起置于与图8所示类似的板中制 成,于是,光接收板在上面而光发射板在它的下面,被安排成背靠背以便从一侧接收光而在 另一侧发射光。这样的结构例如能够在生态温室中使用。当太阳升起时,向太阳电池板充 电,而当太阳下山时,被储存的电荷通过该结构的另一侧馈送回去,把储存的能量转换回光 能,从而确保温室总是被照亮(适当的电连接被提供)。
[0054] 这种技术还能用于有薄膜电池置于一圆顶上的光致电压反射板。这种板能够依照 该圆顶的外形来安排,因此随着太阳在白天越过天空的运动,该板能够从大气吸收更多的 可用光能。
[0055] 按照本发明的太阳电池板,还能送达遥远的地方并能卷起来以便运输。再次指出, 该板可以是双侧太阳电池板/光板。
[0056] 图10画出图9所示背靠背板合并到街灯中的另一种使用。该灯有支承30,其上放置按照本发明的光发射板31,板31上面是罩或盖32。该罩或盖在其上表面承载一系列太 阳电池板33,而光发射板被承载在光发射器盘34的下表面上,这些板被适当地电连接。这 样的结构对街灯是有用的,这种灯将在白天吸收光而在晚上发射光。它还能用于照明的标 柱、双侧标志、公交站显示器和许多其他应用。
[0057] 图11画出本发明提供光发射和接收设备的另一种应用。利用如图11所示的结 构,光发射和接收板可以被安排成在一侧接收太阳光又在同一侧发射光,如由箭头40,41 所示。
[0058] 图12画出该结构的部分截面视图,还是一样,用相同的参考数字表示图2到4和 6及7所示那些类似部分。因此,该板与图4和7所示那些配置类似,但以从顶部开始的层 的形式包括:透光基片4、可以充当发射器43的第一场致发光导电聚合物透光网格、第二导 电层44、光致电压的第二场致发光导电聚合物透光网格45、可以包括反射板11并在第二网 格45内的集成反射板7、类似于图7所示在集成反射板下面的那些薄膜电池的薄膜电池23 和背衬5。提供用于电连接各层的装置(未画出),从而使该设备能够在同一侧收集光和发 射光。
[0059] 因此,该板使用堆叠在光致电压上的光发射器导体聚合物,并合并和共享同一反 射层。
[0060] 这种类型的板对照明的交通标柱、街道标志和街道商店前的显示器特别有用。此 夕卜,二重层能力(dual layer power)也可以用于节省空间、金钱和100%无碳排放的生态温室。
[0061] 合并在板内的适当的集成开关控制器(未画出),能够被安排来感测光致电压网 格的电压降落,然后切换,以便从电池内储存的能量转换到光发射第一透光网格,该光发射 的第一透光网格将合适地发射光。
[0062] 如有需要,一些来自电压膜网格的表面能量,能够被连接到一系列备用电池(未 画出),以便在发射光时,有更好的性能。
[0063] 该二重用途的板反射进入的光,以便被光致电压膜会聚,之后消耗由光发射膜发 射的光。该二重用途降低了板尺寸并节省了生产针对两种分开功能的板的成本。
[0064] 图13画出这种类型板如何能够用在参考数字50表示的交通标柱和用该板提供的 侧面51。
