具体实施方式
请同时参照图1及图2，其是分别绘示依照本发明的第一实施方式的一种出光装置的导光板在第一配置形态与第二配置形态时的使用状态示意图。本实施方式的出光装置100主要包含导光板110以及光源120。导光板110包含主体111，且主体111具有入光面111a。光源120邻设于入光面111a，以提供光线至导光板110中。在本实施例中，导光板110可以选择为不同的配置形态，以提供不同的出光效果。
请继续参照图1，当导光板110在第一配置形态时，导光板110可提供朝向第一方向D1的第一出光功能，以及朝向第二方向D2的第二出光功能。当导光板110在第二配置形态时，原本朝向第二方向D2的第二出光功能已被改变，且原本朝向第一方向D1的第一出光功能也已被改变。需要说明的是，在此所指的“出光功能”具有辉度特性、色度特性及/或指向特性。其中，若改变辉度特性、色度特性与指向特性中的一者或多者，则出光功能也会随之改变。在一例子中，辉度特性可为出光量，色度特性可为出光颜色，指性特性可为光线的出光指向性。
在本实施例中，导光板110的主体111还具有第一出光面111b以及第二出光面111c。第一出光面111b与第二出光面111c分别连接于入光面111a的相对两侧。其中，第一出光面111b具有第一出光功能，且第二出光面111c具有第二出光功能。在本实施例中，第一出光面111b上设有多个第一反射结构112。因此，光源120所提供的光线的一部分可从第一出光面111b射出，一部分则会被第一反射结构112反射而从第二出光面111c射出。由此，从第二出光面111c所射出的光线除了包含光源120所直接提供的光线外，还包含了被第一反射结构112所反射的光线，故从第二出光面111c射出的出光量比从第一出光面111b所射出的出光量多。也就是说，第一出光面111b的第一出光功能不同于第二出光面111c的第二出光功能。在一实施例中，第一反射结构112可通过印刷或涂布的方式设置在第一出光面111b上。在一例子中，通过改变第一反射结构112的结构形状与排列密度，可达到调配从第一出光面111b与第二出光面111c的出光比例的目的。
如图1所示，当导光板110在第一配置形态时，第一出光面111b朝向第一方向D1，以提供第一出光功能，第二出光面111c则朝向第二方向D2，以提供第二出光功能。如图2所示，当导光板110在第二配置形态时，第二出光面111c朝向第一方向D1，以提供第二出光功能，而第一出光面111b则朝向第二方向D2，以提供第一出光功能。也就是说，通过改变导光板110的不同配置方式，可达到改变导光板110朝向第一方向D1与第二方向D2的出光功能的目的。
本发明中，出光装置还可以有不同的结构设计。请同时参照图3及图4，其是分别绘示依照本发明的第二实施方式的一种出光装置的导光板在第一配置形态与第二配置形态时的使用状态示意图。本实施方式的出光装置200主要包含导光板210以及光源220。导光板210包含主体211，且主体211具有入光面211a、第一出光面211b以及第二出光面211c，且第一出光面211b与第二出光面211c分别连接于入光面211a的相对两侧。光源220邻设于入光面211a，以提供光线至导光板210中。其中，第一出光面211b具有第一出光功能，且第二出光面211c具有第二出光功能。
如图3及图4所示，第一出光面211b上设有多个第一反射结构212，第二出光面211c上设有多个第二反射结构213。其中，每一个第二反射结构213的本身形态(inherent type)或排列密度不同于每一个第一反射结构212的本身形态或排列密度。需要说明的是，在此所指的“本身形态”指第一反射结构212与第二反射结构213的结构特征，例如结构形状、高度、深度及宽度。由此，光源220所提供的光线从第二出光面211c所射出的出光量与从第一出光面211b所射出的出光量不同，从而使得第一出光面211b所产生的第一辉度特性不同于第二出光面211c所产生的第二辉度特性。因此，第一出光面211b的第一出光功能不同于第二出光面211c的第二出光功能。
在本实施例中，导光板210还包含倾斜结构230，且倾斜结构230设置在主体211的远离入光面211a的一端。其中，倾斜结构230具有倾斜面231，且倾斜面231相对于第一出光面211b与第二出光面211c倾斜。在本实施例中，倾斜面231与第二出光面211c之间形成锐角，故光源220所产生的部分光线经倾斜面231反射后，可从第二出光面211c出光，进而改变光线从第二出光面211c的出光量。在其他实施例中，倾斜面231上还可设置第三反射结构232，同样可达到改变第二出光面211c的出光量的目的。在另一实施例中，还可以通过改变倾斜面231的倾斜程度来改变第二出光面211c的出光量。
在一些实施例中，第一反射结构212、第二反射结构213与第三反射结构232通过印刷或涂布的方式形成。而且，通过改变第一反射结构212、第二反射结构213与第三反射结构232的结构形状或排列密度的方式，也可达到调配从第一出光面211b与第二出光面211c的出光比例的目的。
如图3所示，当导光板210在第一配置形态时，第一出光面211b朝向第一方向D1提供第一出光功能，第二出光面211c则朝向第二方向D2提供第二出光功能。如图4所示，当导光板210在第二配置形态时，第二出光面211c朝向第一方向D1提供第二出光功能，而第一出光面211b则朝向第二方向D2提供第一出光功能。也就是说，通过改变导光板210的配 置方式，可达到改变导光板210朝向第一方向D1与第二方向D2的出光功能的目的。
在前述实施例中，第一反射结构、第二反射结构以及第三反射结构直接设置在导光板的主体上。通过改变导光板的设置方向来达到改变导光板分别朝向第一方向与第二方向的出光功能的目的。在其他实施例中，还可以不改变导光板的设置方向来达到改变导光板的出光功能的目的。
请参照图5及图6，其是分别绘示依照本发明的第三实施方式的一种出光装置的导光板在第一配置形态与第二配置形态时的使用状态示意图。本实施方式的出光装置300主要包含导光板310以及光源320。导光板310包含主体311，且主体311包含入光面311a、第一出光面311b以及第二出光面311c。第一出光面311b与第二出光面311c分别连接于入光面311a的相对两侧。光源320邻设于入光面311a，以提供光线至导光板310中。在一实施例中，导光板310具有调光组件，且调光组件可设置在第一出光面311b或第二出光面311c上。本实施方式的调光组件包含第一光学膜片312，且第一光学膜片312上设有多个第一光学结构312a。本实施方式的第一光学结构312a主要用于反射光线，以达到调配光线从第一出光面311b与第二出光面311c的出光量的目的。在一实施例中，第一光学结构312a的结构形状与排列密度还可以依据不同的使用需求来设计。
请参照图5所示，当导光板310在第一配置形态时，第一光学膜片312安装于第一出光面311b上。因此，从第一出光面311b射出的光线的一部分会通过第一光学膜片312，另一部分则会被第一光学膜片312反射而从第二出光面311c射出，从而使得导光板310具有朝向第一方向D1的第一出光功能。此外，从第二出光面311c射出的光线除了包含光源320所直接提供的光线外，还包含了经第一光学膜片312反射的光线，故可使导光板310具有朝向第二方向D2的第二出光功能。请参照图6所示，当导光板310在第二配置形态时，第一光学膜片312安装于第二出光面311c上。因此，从第二出光面311c射出的光线的一部分会通过第一光学膜片312，另一部分则会被第一光学膜片312反射而从第一出光面311b射出，从而使得导光板310原本朝向第二方向D2的第二出光功能已被改变。同 样地，从第一出光面311b射出的光线除了包含光源320所直接提供的光线外，还包含了经第一光学膜片312反射的光线，故使得导光板310原本朝向第一方向D1的第一出光功能也被改变。
本发明中，调光组件还可以具有不同的结构设计。请同时参照图7及图8，其是分别绘示依照本发明的第四实施方式的一种出光装置的导光板在第一配置形态与第二配置形态时的使用状态示意图。本实施方式的出光装置400主要包含导光板410以及光源420。导光板410包含主体411，且主体411包含入光面411a、第一出光面411b以及第二出光面411c。第一出光面411b与第二出光面411c分别连接于入光面411a的相对两侧。光源420邻设于入光面411a，以提供光线至导光板410中。
本实施方式的导光板410同样具有调光组件，且调光组件包含第一光学膜片412以及第二光学膜片413。其中，第一光学膜片412上设有多个第一光学结构412a，第二光学膜片413上设有多个第二光学结构413a。而且，第二光学结构413a的本身形态或排列密度不同于第一光学结构412a的本身形态或排列密度。因此，光源420所提供的光线通过第一光学膜片412的出光量与光线通过第二光学膜片413的出光量也会不同。需要说明的是，本实施方式的第一光学结构412a与第二光学结构413a与前述的第一光学结构312a的设计方式及功能均相同，故于此不再赘述。
请继续参照图7及图8，在本实施例中，导光板410还包含倾斜结构430，且倾斜结构430设置在主体411的远离入光面411a的一端。其中，倾斜结构430具有倾斜面431，且倾斜面431相对于第一出光面411b与第二出光面411c倾斜。在本实施例中，倾斜面431与第二出光面411c之间形成锐角，故光源420所产生的部分光线经倾斜面431反射后，可从第二出光面411c出光，进而改变光线从第二出光面411c的出光量。在其他实施例中，倾斜面431上还可以设置第三反射结构432以反射光线，同样可达到改变第二出光面411c的出光量的目的。在另一实施例中，还可以通过改变倾斜面431的倾斜程度来改变第二出光面411c的出光量。
请参照图7所示，当导光板410在第一配置形态时，第一光学膜片412安装于第一出光面411b上，第二光学膜片413则安装于第二出光面 411c上，以使导光板410的第一出光面411b具有朝向第一方向D1的第一出光功能，且第二出光面411c具有朝向第二方向D2的第二出光功能。请参照图8所示，当导光板410在第二配置形态时，第一光学膜片412安装于第二出光面411c上，第二光学膜片413则安装于第一出光面411b上，使得导光板410原本朝向第一方向D1的第一出光功能已被改变，且原本朝向第二方向D2的第二出光功能也被改变。
需要说明的是，前述实施例用光学膜片来作为调光组件，以达到调整导光板朝向第一方向与第二方向的出光量与出光辉度的目的。在其他实施例中，调光组件还可以为具有调整出光色度功能的彩色滤光片。
请同时参照图9及图10，其是分别绘示依照本发明的第五实施方式的一种出光装置的导光板在第一配置形态与第二配置形态时的使用状态示意图。本实施方式的出光装置500主要包含导光板510以及光源520。导光板510包含主体511，且主体511包含入光面511a、第一出光面511b以及第二出光面511c。第一出光面511b与第二出光面511c分别连接于入光面511a的相对两侧。光源520邻设于入光面511a，以提供光线至导光板510中。
本实施方式的导光板510同样包含调光组件，本实施方式的调光组件包含彩色滤光片512，且彩色滤光片512设置在第一出光面511b上。因此，从第一出光面511b射出的光线在通过彩色滤光片512后，可形成具有不同色度的光线，从而使得第一出光面511b所产生的第一色度特性不同于第二出光面511c所产生的第二色度特性。
请参照图9所示，当导光板510在第一配置形态时，第一出光面511b朝向第一方向D1，第二出光面511c朝向第二方向D2。彩色滤光片512安装于第一出光面511b上。因此，光线从第一出光面511b射出而通过彩色滤光片512后，会形成具有不同色度的光线，从而使得导光板510具有朝向第一方向D1的第一出光功能。光源520所提供的光线直接从第二出光面511c射出后则使导光板510具有朝向第二方向D2的第二出光功能。请参照图10所示，当导光板510在第二配置形态时，第一出光面511b朝向第二方向D2，第二出光面511c则朝向第一方向D1。并且，彩色滤光片 512同样安装于第一出光面511b上。因此，光源520所提供的光线可从第二出光面511c朝向第一方向D1射出，这改变了导光板510原本朝向第一方向D1的第一出光功能。从第一出光面511b射出而通过彩色滤光片512的光线则朝向第二方向D2射出，这也改变了原本朝向第二方向D2的第二出光功能。
在其他实施例中，当导光板510在第一配置形态时，彩色滤光片512也可设置在第二出光面511c上，而当导光板510在第二配置形态时，彩色滤光片512则设置在第一出光面511b上，也可达到改变导光板510原有的朝向第一方向的第一出光功能以及导光板510朝向第二方向的第二出光功能的目的。或者，在一些实施例中，彩色滤光片512包含第一彩色滤光片及第二彩色滤光片。当导光板510在第一配置形态时，第一彩色滤光片设置在第一出光面511b，第二彩色滤光片设置在第二出光面511c上，而当导光板510在第二配置形态时，第一彩色滤光片设置在第二出光面511c，第二彩色滤光片设置在第一出光面511b上，同样可达到改变导光板510原有的朝向第一方向的第一出光功能以及导光板510朝向第二方向的第二出光功能的目的。
在其他实施例中，调光组件也可为具有调整出光指向性功能的棱镜片。请同时参照图11及图12，其是分别绘示依照本发明的第六实施方式的一种出光装置的导光板在第一配置形态与第二配置形态时的使用状态示意图。本实施方式的出光装置600主要包含导光板610以及光源620。导光板610包含主体611，且主体611包含入光面611a、第一出光面611b以及第二出光面611c。第一出光面611b与第二出光面611c分别连接于入光面611a的相对两侧。光源620邻设于入光面611a，以提供光线至导光板610中。
本实施方式的导光板610同样包含调光组件，且调光组件包含棱镜片612，且棱镜片612设置在第二出光面611c上。因此，从第二出光面611c射出的光线在通过棱镜片612后，可形成具有不同出光指向性的光线，从而使得第一出光面611b所产生的第一指向特性不同于第二出光面611c所产生的第二指向特性。
请参照图11所示，当导光板610在第一配置形态时，第一出光面611b朝向第一方向D1，第二出光面611c朝向第二方向D2。而且，棱镜片612安装在第二出光面611c上。因此，导光板610可提供朝向第一方向D1的第一出光功能，以及朝向第二方向D2的第二出光功能。请参照图12所示，当导光板610在第二配置形态时，第一出光面611b朝向第二方向D2，第二出光面611c则朝向第一方向D1。并且，棱镜片612安装于第一出光面611b上，这改变了导光板610原本朝向第二方向D2的第二出光功能，以及导光板610原本朝向第一方向D1的第一出光功能。
在其他实施例中，当导光板610在第一配置形态时，棱镜片612也可设置在第二出光面611c上，而当导光板610在第二配置形态时，棱镜片612则设置在第一出光面611b上，也可达到改变导光板610原有的朝向第一方向的第一出光功能以及导光板610朝向第二方向的第二出光功能的目的。或者，在一些实施例中，棱镜片612包含第一棱镜片及第二棱镜片。当导光板610在第一配置形态时，第一棱镜片设置在第一出光面611b，第二棱镜片设置在第二出光面611c上，而当导光板610在第二配置形态时，第一棱镜片设置在第二出光面611c，第二棱镜片设置在第一出光面611b上，同样可达到改变导光板610原有的朝向第一方向的第一出光功能以及导光板610朝向第二方向的第二出光功能的目的。
由上述本发明实施方式可知，本发明通过改变导光板的配置形态，例如导光板的设置方向，或导光板搭配调光组件的使用，来改变导光板原有的朝向第一方向的第一出光功能以及导光板朝向第二方向的第二出光功能。由此，使用者可利用同一个出光装置来调整导光板的配置形态，以使出光装置产生不同的出光功能，进而满足不同的使用需求。
虽然本发明已经通过实施例进行如上公开，然而其并非用于限定本发明，任何本领域的技术人员在不脱离本发明的精神和范围内，应当可以作出些许更动与润饰，故本发明的保护范围当视所附权利要求所界定的范围为准。
