优选的，在上述耐候光激发灯箱中，所述多光谱光源的波长范围为350-700nm。
优选的，在上述耐候光激发灯箱中，还包括电源控制装置，所述电源控制装置为声控装置、光感控制装置或红外感应控制装置。
优选的，在上述耐候光激发灯箱中，所述耐候发光层、导光板和反光层尺寸相同。
由以上技术方案可见，本发明提供的灯箱,其中耐候发光层在光源光的激发下，自身能够发光，当用于灯箱中时，与导光板配合，能避免出现目前灯箱中画面存在的透光性差，使得光线强度衰减的问题，反而会因为光激发发光的效果，使得灯箱中广告画面的明亮度更高，因此更节约电能。耐候发光层可以为彩色的，广告画面为彩色画面，此时画面均匀靓丽、色彩度更好、立体感更强且耐候性较好。综上所述，本发明提供的耐候光激发光源灯箱使用性能更好。
在本发明中，所述灯箱包括导光板、多光谱光源和散热保护框，任选的，反光板，耐候发光层、紫外屏蔽层和多余光屏蔽层中的一种或者多种，其中，所述反光板设置在导光板背部，所述耐候发光层设置在所述导光板前部，所述紫外屏蔽层设置在所述耐候发光层前部，所述多余光屏蔽层设置在耐候发光层前部或者耐候发光层与紫外屏蔽层之间。
在本发明中，所述导光板是透明材质的、纳米亚克力板或者激光打点导光板，优选为纳米亚克力板，本发明人发现，由多光谱光源发出的光线经过纳米亚克力导光板，光线在其内部传导，从而在可视方向呈现均匀分布的视觉效果，即，无明显的明暗区，从而视觉效果佳。
在本发明一种优选的实施方式中，所述导光板是能够光致发光的。
在本发明一种优选的实施方式中，在制备所述导光板的原料中加入光致发光剂， 使得所述导光板本身能够光致发光，或者，在导光板上涂布光致发光剂，或者将光致发光剂涂布于透明载体上，再将所述透明载体贴覆于所述导光板表面，从而使导光板能够光致发光。
在本发明中，具有不同颜色的光致发光剂加入制备所述导光板的原料中形成不同颜色的原料后，不同颜色的原料共同制备成具有特定形状或图案的导光板。
在本发明中，不同颜色的光致发光剂在透明载体上也可以形成特定的图案，再贴覆于导光板表面。
在本发明中，所述导光板的厚度为1.5～6mm，优选为3～5mm，即可满足刚性强度和发光强度的双重需求。
在本发明中，所述多光谱光源选自LED灯或者激光光源。
在本发明中，所述多光谱光源优选为LED灯，由于LED灯是用蓝光引发黄色荧光，综合而成白光，但是在实际使用中总会有蓝光剩余而逸出，这些蓝光虽然不易被人眼察觉，但是对人眼具有较大的伤害，而这些对人体有害的多余出来的蓝光正好可以被光致发光剂所利用，激发其发出荧光，从而增加灯箱的亮度，因此，本发明优选使用LED灯作为多光谱光源，一方面节约能源，另一方面能够利用其蓝光。
在本发明中，所述多光谱光源的波长范围是350～700nm，优选为350～570nm，本发明人发现，上述波长范围的光线属于近紫外光，具有较多的蓝光，而本发明的灯箱正是利用了该蓝光来激发光致发光剂发光。
在本发明中，所述多光谱光源设置在所述导光板周围或者背部。
由于所述多光谱光源的照射导光板范围超过40cm时光通量会有严重衰减，因此，当所述灯箱的体积较小时，所述多光谱光源设置于所述导光板的周围，即可满足光线强度的需求；而当所述灯箱体积较大时，需要将所述光源设置于所述导光板的背部，即，所述导光板与所述反光板之间，从而满足导光板对光强度的要求。
在本发明中，当多光谱光源设置在所述导光板周围时，所述导光板与所述反光板贴合；当多光谱光源设置在所述导光板背部时，所述导光板与所述反光板之间的距离为3～15cm，优选为3～6cm，本发明人发现，当所述导光板与所述反光板之间的距离为3～15cm时，在导光板上不会形成明显的明暗区，同时光强度大，而当它们之间的距离小于3cm时，在导光板上会形成明显的明暗区，影响灯箱的美观，当它们之间的距离大于15cm时，导光板上的光强度弱，不能达到灯箱亮化的效果。
在本发明中，所述光致发光剂选自发光油墨、墨水、荧光粉、导光粉、有机树脂油墨、墨水和颜料中的一种或者多种，优选为发光油墨、墨水，荧光粉和导光粉的组合物。
在本发明中，所述荧光粉是主要的光致发光材料，在多光谱光源发出的光线照射后，能够发射出不同颜色和亮度的荧光。
在本发明中，所述导光粉用于将多光谱光源发出的光线以及荧光粉发出的荧光均匀导出导光板，使得所述灯箱的亮度更大。
本发明人发现，光致发光剂中的各组分协同作用，发光油墨、发光墨水、荧光粉、有机树脂油墨、墨水和颜料等组分能够在多光谱光源的照射下或者发出荧光，或者散射光线，这些发出的荧光或者散射光线再被导光板导出，从而增加了所述灯箱的亮度。
在本发明中，所述耐候发光层是由光致发光剂形成的，优选地，所述耐候发光层是光致发光剂涂布在所述导光板表面而形成的，更优选地，根据需要，所述耐候发光层可使用多种彩色组合成特定图案。
在本发明中，当导光板中不含有光致发光剂时，所述耐候发光层则起到光致发光作用，其中的光致发光剂在经过多光谱光源发出的光线照射后，能够发出荧光。
在本发明中，所述紫外屏蔽层是由紫外屏蔽剂形成的，其是在导光板的前表面，或者在耐候发光层的前表面由紫外屏蔽剂涂布形成的。
在本发明中，所述紫外屏蔽层能够阻挡太阳光中的紫外线对光致发光剂的分解，从而使得光致发光剂能够在较长的时间内保持颜色鲜艳而不褪色，即，使所述灯箱具有较强的耐候性。
在本发明中，所述多余光屏蔽层是由特定射线屏蔽剂在所述紫外屏蔽层或者导光板的前部经过涂布形成的，其用于屏蔽由灯箱所发出的对人体或者环境有害的射线，或者屏蔽来自环境的，对灯箱有害的射线。
在本发明中，所述反光板是指透光率小于10％的板材或者薄膜，或者是贴覆有透光率小于10％薄膜的板材，其主要作用是将射向反光板的光线反射回导光板，使得光线更为充分的利用，灯箱的发光强度更高，更为节能。
在本发明中，所述散热保护框是金属制的，其是由首尾顺次相接的金属条或者空心金属筒制成，在所述散热保护框内周上开设有用于卡设导光板、反光板以及耐候发光层、紫外屏蔽层和多余光屏蔽层的凹槽，其内轮廓与所述导光板的外形相匹配，即， 所述导光板能够恰好卡夹于所述散热保护框内，所述散热保护框其用于对多光谱光源以及导光板进行散热，从而使得所述耐候光激发灯箱保持较低的运行温度，从而延长所述灯箱的使用寿命，同时，其对导光板、反光板等起到撞击保护的作用，防止导光板、反光板等被撞击后破损，另外，所述散热保护框对所述灯箱还能够起到装饰作用。
在本发明另一种优选的实施方式中，所述灯箱还可以不包括反光板，所述多光谱光源设置在所述导光板周围，在所述导光板两侧分别任选地设置有耐候发光层、紫外屏蔽层和多余光屏蔽层中的一种或者多种，其中，所述导光板、耐候发光层、紫外屏蔽层和多余光屏蔽层如前所述。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例所需要使用的附图作简单地介绍，显而易见地，对于本领域普通技术人员而言，在不付出创造性劳动 的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
本发明实施例提供一种耐候光激发灯箱，以解决现有技术中的广告灯箱画面清晰度、亮度、透光率和耐候性较差的问题。
为了使本技术领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
实施例一
请结合参考图1，如图1所示的一种耐候光激发灯箱的拆分结构，从外向内依次包括耐候发光层1、导光板2和反光层5(在本发明，反光层即为反光板)，以及多光谱光源3；所述多光谱光源3射向所述耐候发光层1中心的方向，多光谱光源3可以分布导光板2的边缘四周，或者置于导光板2的一侧，光源射向耐候发光层1的中心。所述耐候发光层1可以直接印刷在一透明材质上，再置于导光板2的一侧，导光板2的另一侧涂布有反光材料将光源反射在导光板2上，所述导光板2可以为纳米亚克力导光板。所述耐候发光层1也可以在导光板2成型时直接融合在其内部。耐候发光层1应用于灯箱中，在无光源照射时，可起到各种油墨的作用，展示广告画面。当通电后，由多光谱光源将其照射后，可以被激发自身发出亮光，且在切断光源后还能恢复没有发光的效果。正是这一特性，使本发明提供的耐候光激发灯箱中广告画面的明亮度更高，因此更节约电能。耐候发光层可以为彩色的，广告画面为彩色画面，此时画面均匀靓丽、色彩度更好、立体感更强且不易褪色，耐候性较好。综上所述，本发明提供的耐候光激发光源灯箱使用性能更好，而且灯箱的结构紧凑，厚度可以做到较 薄，例如厚度可以为2mm。
上述耐候发光层可以为包括发光油墨层、发光墨水层或发光颜料层，以及发光物的混合物质。将其应用在灯具中时，可以将其置于灯罩表面或直接注塑于灯罩内，通过光源激发发光物将光传导出来，避免因为罩有灯罩而光线强度衰减的问题，且由于发光物被激发，相比于普通灯具亮度更高，更节能。
为了实现更好的光激发耐候发光层1发光的效果，所述多光谱光源3为LED光源或激光光源。所述多光谱光源3的波长范围为350-700nm。
在上述耐候光激发灯箱中，还包括设置在所述耐候发光层1远离所述导光板2一侧的多余光谱屏蔽层6，屏蔽各种光激发不需要的光谱，达到耐候和护眼的功能。所述多余光谱屏蔽层6可以直接覆盖在耐候发光层1的表面或置于前一侧。
在上述耐候光激发灯箱中，还包括包覆在所述导光板2边缘的散热保护框4，达到装饰和辅助散热的目的。
所述电源控制装置7可以通过感应周围环境光线的明暗，声音的大小，感应有无人员在周围来控制7电源通断以及光线的明暗，从而达到智能节能的目的；在上述耐候光激发灯箱中，所述电源控制装置7可以为声控装置、光感控制装置或红外感应控制装置。
实施例二
请结合参考图2，如图为一种全角度(双面)灯箱，与实施例一的区别之处在于，在灯箱的两个面均设置有耐候发光层1，达到全角度展示画面内容的效果。具体工作过程和说明请参考实施例一的相关部分，此不赘述。
实施例三
请结合图1，该图形象的示出了本发明提供的耐候光激发灯箱的组装结构。如图所示，从外向内依次包括光激发发光层1、导光板2和反光层5，以及多光谱光源3和电源控制装置7；所述多光谱光源3射向所述光激发发光层1中心的方向。还包括包覆在所述反光层边缘的散热保护框4。还包括设置在所述导光板2不安装所述光激发发光层1那一侧的多余光谱屏蔽层6，屏蔽各种光激发不需要的光谱，达到耐候和护眼的功能。
本发明提供的耐候光激发灯箱的制作方法如下：
首先，根据灯箱用途,选定导光板尺寸和材质，在所述导光板2的一侧平行安装等尺寸的反光板5；导光板2的材质可以为纳米亚克力板。反光板5的作用是将光源发射至导光板2上，从而减少光强度损耗。
其次，将光激发发光物结合在所述导光板2上，所述光激发发光物包括荧光粉和导光粉，还包括有机树脂油墨、墨水或颜料。荧光粉的种类为多种，通过一定的工艺制备好的光激发发光物，当受到一定波段的光源激发后，光激发发光物发出亮光。在与所述反光板5和光激发发光物组合后的导光板的四周边缘位置布设多光谱光源3，所述多光谱光源3射向所述导光板2中心的方向，所述多光谱光源的波长范围为350-700nm。
因此，这种灯箱中光源的强度不会因导光板阻挡而在向外扩散的过程中产生衰减，反而会通过导光粉将“光”传导出来，这里的光不仅包括光源光，也包括因为荧光粉被激发而发出的光，也就是说，相比于其他类型的灯箱透光率更高，广告画面的光强更亮，如果是彩色画面，则更逼真鲜艳立体。而且，灯箱更节能省电，耐候性也应多余光谱屏蔽层的应用而更好。
为了更加形象的说明透光率的问题，现举照明灯具为例，目前市场常规灯具一般都是由日光灯管，三基色节能灯或LED灯管，LED球泡灯外置灯罩构成，这些灯具的共同点都是在光源外罩有(白色、彩色)玻璃或塑料灯罩，光源通过灯罩向外扩散要靠灯罩里添加的扩散粉，扩散粉在散射光线过程中会衰减20％左右的光线强度(若是彩色可能衰减掉55--60％的光线强度)。而用荧光粉和导光粉代替灯罩内的扩散粉，在辅助特定波长的光源(可以为激光光源或LED光源)激发荧光粉，在用电相同的情况下，光激发照明灯具比普通照明灯具节能将近6倍，换个说法也就是光激发照明2W的亮度与普通照明12W的亮度几乎相同。这一应用解决了长久以来照明行业彩色灯具亮度低，透光率差的难题，即使是多种颜色混合的灯具，也不太影响亮度。同样的，基于本发明提供的耐候光激发物质还可以应用于指示牌或者指示标识中。
其中，将光激发发光物结合在所述导光板2上，所述光激发发光物包括荧光粉和导光粉，还包括有机树脂油墨、墨水或颜料具体是指：将所述光激发发光物印刷在所述导光板2未安装反光板5的一侧，印刷方式可以为打印、凹印或喷绘等。也可以印刷在导光板的两侧。并且在导光板的两侧均安装发光板，制作为双面灯箱。或者，将所述光激发发光物混合于制作所述导光板的原料中注塑成型，因此当光激发发光物质为彩色时，就能使得灯箱更耐候。
在上述耐候光激发灯箱的制作方法中，还包括在所述导光板的四周安装金属散热保护框4，使得灯箱使用寿命更长。
根据灯箱实际使用的特点，在上述耐候光激发灯箱的制作方法中，还包括安装与所述多光源电源电连接的电源控制装置7，用于控制所述多光源电源的开关和明亮。所述电源控制装置可以通过感应周围环境光线的明暗，声音的大小，感应有无人员在周围来控制电源通断以及光线的明暗，从而达到智能节能的目的；在上述耐候光激发灯箱中，所述电源控制装置7可以为声控装置、光感控制装置或红外感应控制装置。
以上所述仅是本发明的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
