如图1至图12所示，本申请揭示了一种灯具100，能够呈现蓝天效果，所述灯具100包括出光箱10和光源箱20，其中，所述光源箱20设置在所述出光箱10的侧面，且所述光源箱20内设有作为主光源的第一光源模组21。需要进行说明的是，所述出光箱10优选为矩形结构，且所述光源箱20设置在所述出光箱10长度方向的侧面，当然，在本申请的其他实施例中，所述光源箱20可以呈分体式且分别设置在所述出光箱10长度方向的两个相对的侧面，具体不做限制。
如图1所示，为使所述灯具100产生窗影效果，所述光源箱20优选设有一个且位于所述出光箱10长度方向的一个侧面，所述出光箱10设有出光腔，所述出光腔包括位于所述出光箱10的侧面的进光口以及位于所述出光箱10的底面的出光口，所述出光箱10底部的出光口设有水平设置的导光板11，所述导光板11的侧面设有与所述导光板11贴合设置的第二光源模组30，所述第二光源模组30作为次光源仅用于将发出的光线入射所述导光板11并用于使所述导光板11呈现出所需颜色。
具体地，以所述灯具100呈现蓝天效果为例，所述第一光源模组21和所述第二光源模组30均为侧发光式，所述第一光源模组21包括若干线性排列的第一光源，所述第一光源为白色光源，所述第一光源也可以采用阵列排列。所述第二光源模组30包括若干呈线性排列的蓝光源，所述第二光源模组30通过向所述导光板11照射，以使得所述导光板11呈蓝色，所述第一光源模组21用于朝向所述出光箱10内照射，并通过所述导光板11将所述第一光源模组21发出的光线从线光源变为面光源，最后从所述导光板11中投射出并最终使得所述导光板11呈现蓝天效果。当然，在本申请的其他实施例中，所述第二光源模组30也可以产生其他颜色或是在多种不同颜色中进行切换，使得所述导光板11根据需要呈现晚霞或其他效果，具体不做任何限制。
在上述实施例中，多个第一光源排列的延伸方向平行于多个蓝光源排列的延伸方向，即相当于所述第一光源模组21平行于所述第二光源模组30，当然，在其他实施例中，所述第二光源模组30可以设置在所述出光箱10长度方向的另一侧，或是四个侧面都设置相同或不同颜色的单色光源，具体可根据需要进行设置，具体不做限制。
如图2和图3所示，可以理解的是，由于所述光源箱20设置在所述出光箱10侧面，而所述导光板11设置在所述出光箱10的底部，所述第二光源模组30相当于设置在所述光源箱20的底部，优选地，所述第二光源模组30可部分延伸至所述光源箱20内，但所述光源箱20和所述第二光源模组30之间仍通过光源箱20的金属壳体进行分隔，使得所述第二光源模组30与所述导光板11位于同一平面，如此以减小所述灯具100在竖直方向上的厚度。
当所述光源箱20和所述第二光源模组30位于所述出光箱10的同一侧时，所述出光箱10宽度方向的侧面还可以设有电源箱(未标号)，所述电源箱内设有与所述第一光源模组21和所述第二光源模组30相连的电源，所述电源箱与所述光源箱20位于同一水平面，且所述电源箱的延伸方向垂直于所述光源箱20的延伸方向。并且，当所述光源箱20和所述第 二光源模组30位于所述出光箱10长度方向的不同侧时，所述电源箱仍可以设置在所述出光箱10宽度方向的侧面，以使得所述电源分别连接所述第一光源模组21和所述第二光源模组30。

所述光源箱20包括光源安装面23，所述第一光源模组21还包括与所述光源安装面23贴合设置的基板，所述第一光源模组21的出光方向垂直于所述光源安装面23所在平面，所述光源箱20内壁还设有散热器24，所述散热器24贴合所述光源安装面23的背面设置，使得所述基板和所述散热器24分别设置在所述光源安装面23的正反面。较佳地，所述光源箱20优选为金属材质，且所述散热器24包括多个散热鳍片，如此以增大与空气的接触面积，增强散热效率。
如图4和图5所示，进一步地，为增强所述灯具100的窗影的真实效果，需要对光源的光线进行截取，较佳地，所述出光箱10和所述光源箱20之间设有截光板25，所述截光板25上开设有透光部251，所述透光部251优选呈矩形，所述第一光源模组21发出的部分光线以此穿过所述透光部251和所述导光板11，并通过所述导光板11射出。上述实施例中的类矩形光斑通过所述截光板25的矩形的透光部251进行物理截取后，能够使得光线均匀并形成清晰的矩形光斑，类似于太阳光通过窗户在墙面上形成的窗影。可以理解的是，所述透光部251可以是开口或透明材质，并且可以通过改变所述透光部251的大小来改变所形成窗影的尺寸。
作为本申请的优选实施例，所述截光板25与所述光源箱20相连，所述截光板25竖直设置，且所述截光板25垂直于所述导光板11所在平面，此时，所述第一光源模组21的发光方向与所述截光板25具有45°-85°夹角，并且在本实施例中，所述光源安装面23相对于所述截光板25倾斜设置，以使得所述第一光源模组21发出的光线相对于所述截光板25倾斜，具体地，所述第一光源模组21的出光方向与水平面之间的夹角位于5°-45°之间。当然，可以理解的是，所述光源安装面23和所述截光板25之间可以相对倾斜，所述光源安装面23与所述截光板25同样具有5°-45°夹角，即，所述截光板25可以相对于竖直平面倾斜，所述光源安装面23可以竖直设置，只要是使得所述第一光源模组21的出光方向朝向所述导光板11即可，具体不做限制。
在本申请的其他实施例中，所述灯具100还包括设置在所述导光板11底部的装饰框40，所述装饰框40环绕所述导光板11设置，且所述装饰框40包括垂直于所述导光板11的第一边框41以及与所述第一边框41相互垂直的第二边框42，所述第一边框41设置在所述导光板11和所述第二边框42之间，所述第二边框42平行于所述导光板11，且所述第二边框42 与所述导光板11之间相隔了所述第一边框41的宽度。
综上所述，本申请的灯体较薄，截光方式简单且能够产生清晰的窗影，使得呈现的蓝天效果更加真实。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
