具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
图1为一种透明拼接装置的结构示意图。如图1所示，该透明拼接装置包括多个透明显示区域120以及用于固定透明显示区域120的箱体110。多个透明显示区域120拼接形成一个完整的透明显示装置；箱体110内可放置待展示的物品。通常，大多数透明拼接装置采用射灯或者发光二极管(Light Emitting Diode，LED)加扩散板作为光源组件，光源组件固定在箱体上为透明拼接装置提供光照。在研究中，本申请的设计人发现：采用射灯作为光源组件会造成 亮度不均匀等问题，并且射灯的尺寸较大，不利于透明拼接装置的窄边框设计。
图2为一种采用LED加扩散板作为光源组件的透明拼接装置的主视示意图。如图2所示，由于采用LED加扩散板组成的光源组件115可能会产生亮度不足等问题，如果需要较高的亮度，就需要在透明拼接装置四周增加LED及扩散板组成的光源组件115的数量。然而，设置在透明拼接装置四周的LED及扩散板组成的光源组件115会对观看造成干扰，影响透明拼接装置的显示效果。
图3为一种用于包括LED和扩散板的光源组件的背板的结构示意图。如图3所示，该光源组件的背板包括用于固定LED灯条的框部1150和用于在其上设置扩散板的板状部分1151。如图3所示，用于设置扩散板的板状部分1151的尺寸较大，因此，其应用范围也会因尺寸较大而受到限制，同时也不利于运输。
本公开实施例提供一种光源组件和背光装置。该光源组件包括光源和灯槽。光源可包括基底和至少一个设置在基底上的发光元件。灯槽可包括多个固定部，光源设置在灯槽内并通过基底固定在多个固定部中的一个；并且，在固定在不同的固定部时，光源的出光方向不同。该光源组件通过在灯槽设置多个固定部可使光源设置在不同固定部时具有不同的出光方向，从而可提供一种出光方向可调的光源组件。因此，该光源组件可通过调节出光方向来提高使用本实施例提供的光源组件的透明拼接装置的展示效果，并且还可避免因将光源设置在透明拼接装置四周而带来的对观看的干扰。另外，该光源组件结构简单，操作方便并可通过简单组合就可适用于不同尺寸的透明拼接装置，从而可节省透明拼接装置的开发成本并缩短开发周期。
下面，结合附图对本公开实施例提供的光源组件和背光装置进行说明。
实施例一
本实施例提供一种光源组件。如图4所示，该光源组件包括光源210和灯槽220。光源210可包括基底211和至少一个设置在基底211上的发光元件212。灯槽220包括多个固定部225，光源210设置在灯槽220内并通过基底211固定在多个固定部225中的一个，也就是说，基底211可固定在多个固定部225中的一个，从而使光源210固定在灯槽220内；并且，在将光源210固定在不同的固定部225时，光源210的出光方向不同。
在本实施例提供的光源组件中，光源210可通过基底211固定在固定部225 中；不同的固定部225可使得基底211具有不同的偏转角度，设置在基底211上的发光元件212发出的光的方向因此改变，从而使得光源210具有不同的出光方向。因此，光源210的出光方向可以通过设置在不同的固定部225来实现调节。由此，本实施例提供的光源组件可通过调节光源的出光方向来合理分配光线，提高光照效果，从而可提高使用本实施例提供的光源组件的透明拼接装置的展示效果，并且还可避免因设置在透明拼接装置四周而带来的对观看的干扰。另外，本实施例提供的光源组件结构简单，操作方便并可通过简单组合就可适用于不同尺寸的透明拼接装置，从而可节省透明拼接装置的开发成本并缩短开发周期。
例如，在本实施例一示例提供的光源组件中，如图4所示，固定部225可沿灯槽的侧壁等距离设置，从而使得光源210的出光方向调节更方便。需要说明的是，还可通过设置固定部的数量来提高出光方向调节的精度。当使用环境需要光源组件的出光方向具有更多选择时，可设置较多的固定部。当使用环境需要光源组件的出光方向较少时，可设置较少的固定部。另外，还可在固定部上设置标尺，从而提供出光方向调节的具体数值。当然，本公开实施例包括但不限于此，固定部亦可不等距设置。例如，固定部可根据实际使用情况中使用较多的出光方向而对应地进行设置。
例如，在本实施例一示例提供的光源组件中，固定部与光源的基底通过卡合方式固定。当然，本公开实施例包括但不限于此，固定部也可通过其他固定方式与光源的基底进一步固定，例如，螺纹固定、销固定、夹持固定等，本公开实施例在此不作限定。
例如，在本实施例一示例提供的光源组件中，如图4所示，固定部225可包括至少一个与基底211的厚度匹配的卡槽结构；也就是说，卡槽结构可通过与基底的厚度匹配来卡合固定基底。当然，本公开实施例包括但不限于此，固定部可采用其他的卡合方式与基底固定并使得光源具有不同的出光方向。
例如，如图4所示，固定部225可包括彼此相对设置在底板221两侧的侧壁222上成对的卡槽结构。图5为图4中光源组件的局部结构示意图。如图5所示，卡槽结构226与光源的基底的厚度相匹配，从而卡合固定基底211。通过设置在底板221两侧的侧壁222上成对的卡槽结构226可使得光源210更加牢固地固定在灯槽220内，可提高光源组件的稳定性。需要说明的是，当侧壁上设置成对的卡槽结构时，成对的卡槽结构的沟槽底部之间的距离可恰好等于 基底的宽度，可使基底固定地更牢固，从而进一步提高光源组件的稳定性。
例如，如图5所示，卡槽结构226可设置于侧壁222上，卡槽结构226包括配置来容纳并卡合基底211的沟槽2260，不同的固定部225的沟槽2260具有不同的偏转角度。由此，当基底211卡合固定在不同的固定部225的沟槽2260中时，由于沟槽2260具有不同的偏转角度，基底211也因此同样具有不同的偏转角度，从而可使得基底211上的发光元件212发出的光具有不同的出光方向。
例如，在本实施例一示例提供的光源组件中，如图5所示，卡槽结构226包括突出于侧壁222表面的两个凸起2261，两个凸起2261之间形成沟槽2260。并且，通过设置两个凸起2261的偏转角度可使得沟槽2260具有一定的偏转角度，进而使得通过基底211固定在卡槽结构226上的光源具有不同的出光方向。
例如，在本实施例另一示例提供的光源组件中，如图6a和6b所示，卡槽结构226包括凹入侧壁222的凹槽2260，凹槽2260即为上述的沟槽2260。如图6a所示，侧壁222的厚度较薄，凹槽2260可由侧壁222向外弯折形成，例如可通过冲压工艺使侧壁上形成如图6a所示的凹槽；如图6b所示，侧壁222的厚度较厚，凹槽2260可通过在侧壁222上开设条状开口形成，例如通过去除侧壁222的一部分材料以形成条状开口。
例如，在本实施例另一示例提供的光源组件中，还包括设置在所述灯槽内的板状的固定板，固定部可以为设置在灯槽内的固定板上的开口(通孔)，所述固定板可通过焊接、铆接或其他固定方式固定在灯槽(例如固定在侧壁上或固定在底板上)内，光源的基底可以插入到这些开口之中，通过设置这些开口的偏转方向使得基底具有偏转方向，从而使得在将光源固定在不同的开口时，光源的出光方向不同。图6c示出了这样的固定板的俯视图，如图6c所示，固定板2250为矩形板，设置在灯槽中的固定板2250上形成有由彼此平行的多个开口2260，如图6d所示，多个开口2260具有不同的偏转方向，这些开口2260即为上述的沟槽2260，从而构成的多个卡槽结构，光源的基底可以分别这些卡槽结构中，从而具有不同的出光方向。如图6d所示，固定板2250固定在在侧壁222上。当然，本公开包括但不限于此，固定板还可以相对于灯槽的侧壁或底板倾斜设置。
例如，在本实施例一示例提供的光源组件中，如图4所示，灯槽220包括底板221以及设置在底板221两侧的侧壁222。设置在底板221两侧的侧壁222 相对设置。需要说明的是，通过将灯槽设置为包括底板以及设置在底板两侧的侧壁，可使得设置在灯槽内的光源的出光更有方向性。当灯槽内设置有反射膜或灯槽自身具有反射能力时，这种设置还可提高光源组件在所需要的出光方向上具有更大的光照强度。
当然，本公开实施例包括但不限于此，例如，灯槽可只包括呈“V”字型设置的两块侧板，或者，灯槽可只包括一块具有弧度的底板。
例如，如图4所示，底板221以及设置在底板221两侧的侧壁222一体成型，从而可减少本实施例提供的光源组件的零件数量，减化结构，避免因零件丢失或安装/使用环境狭窄而导致的各种不便。
例如，在本实施例一示例提供的光源组件中，如图4所示，固定部225可设置于侧壁222上。当然，本公开实施例包括但不限于此，固定部也可设置于底板上。
例如，如图4所示，固定部225与侧壁222一体成型，从而可进一步减少本实施例提供的光源组件的零件数量，减化结构，避免因零件丢失或安装/使用环境狭窄而导致的各种不便。
例如，在本实施例一示例提供的光源组件中，如图4所示，光源210可包括基底211以及设置在基底211上的多个发光二极管(Light Emitting Diode，LED)。需要说明的是，基底上LED的数量可根据实际需要的亮度来设置。并且，还可通过设置基底上LED的分布密度来提高或减少亮度，本公开实施例在此不作限定。
例如，在本实施例一示例提供的光源组件中，如图4所示，基底211可为印刷电路板(Printed Circuit Board，PCB)。由此，基底211不仅可为多个发光元件211提供支撑，还可为多个发光元件211提供电源和控制电路。需要说明的是，可通过设置在基底上的控制电路使得多个发光元件分时工作以提高多个发光元件的使用寿命。另外，还可通过设置在基底上的控制电路来控制多个发光元件中发光的顺序和数量来提供各种光照效果，例如，闪烁、渐变等效果，本公开实施例在此不作限定。
例如，在本实施例一示例提供的光源组件中，多个发光元件211可发出不同颜色的光，从而可提供彩色的光照效果。
例如，基底可为柔性印刷电路板(Flexible Printed Circuit Board，FPCB)，从而可使得光源组件便于运输和组装。
例如，该光源可制备为LED灯条。
例如，在本实施例一示例提供的光源组件中，如图4所示，灯槽220的内侧上还可设置有反射膜229。由此，光源210发出的光可被反射膜229反射，从而可提高光能的利用率。
例如，反射膜可为涂覆在灯槽上的白色反光材料或金属镀层。
或者，例如，灯槽可采用反光材料制作，从而即使不设置反射膜也可反射光源发出的光以提高光能的利用率。
例如，在本实施例一示例提供的光源组件中，如图7a所示，沟槽2260的内侧壁还可设置弹性元件2263，从而使得卡合固定在沟槽2260中的基底211更牢固。另外，弹性元件2263还可在光源组件的安装过程中对基底211提供保护，防止基底211与沟槽2260因碰撞或摩擦导致的损伤，从而提高光源组件的使用寿命。
例如，在本实施例一示例提供的光源组件中，侧壁以及设置在侧壁上的卡槽结构可采用具有韧性的材料制作，例如，塑料等。此时，基底的厚度可设置为略微大于卡槽结构的沟槽的宽度，从而可使基底更加牢固地固定在侧壁上。当然，本公开实施例包括但不限于此。
例如，在本实施例一示例提供的光源组件中，如图7b所示，卡槽结构的沟槽2260内侧可设置倒齿2262，基底211对应地也设置与沟槽2260内侧的倒齿2262相配合的倒齿2112，从而可使得基底211更加牢固地固定在侧壁222上。需要说明的是，当卡槽结构的沟槽内侧可设置有倒齿，并且基底对应地也设置又与沟槽内侧的倒齿相配合的倒齿时，基底可从灯槽的侧面滑入上述沟槽中，或者，当卡槽结构采用具有韧性的材料时，基底可直接插入上述沟槽，本公开实施例在此不做限定。
例如，在本实施例一示例提供的光源组件中，如图8所示，底板221两侧的侧壁222呈彼此相对设置的弧形结构。
例如，在本实施例一示例提供的光源组件中，如图8所示，上述弧形结构可为以基底211的宽度为直径的圆弧。如图8所示，基底211可通过固定在不同的固定部225从而在上述的弧形结构中偏转并且在偏转不同角度时，对应的固定部225之间的距离始终保持一致，即基底211的宽度，从而可保证在基底211可在上述的弧形结构中偏转并且在偏转不同角度时，固定部225都可将基底211牢固地固定在侧壁222上。由此，除了出光方向不同以外，当基底211 固定在不同的固定部225时，光源的出光亮度更加稳定。需要说明的是，上述的基底的宽度是指基底在卡合在上述孤形结构时与两个侧壁接触的两边之间的距离。
实施例二
本实施例提供一种背光装置，如图9所示，上述背光装置包括实施例一所述的任一光源组件。由于该背光装置包括实施例一中任一的光源组件，因此，该背光装置具有与光源组件的效果对应的效果，重复之处在此不再赘述。
例如，在本实施例一示例提供的背光装置中，如图9所示，光源组件200至少设置在背光装置的边角位置。由此，在背光装置的边角位置设置的光源组件200可通过调节光源的出光方向来合理分配光线，提高光照效果，从而可提高使用本实施例提供的光源组件的透明拼接装置的展示效果；并且还可避免因设置在透明拼接装置四周而带来的对观看的干扰。
例如，在本实施例一示例提供的背光装置中，该背光装置可用于透明拼接装置中，例如，广告展示柜、实物展示箱等。
实施例三
本实施例提供一种显示装置，其可包括实施例二中任一示例所描述的背光装置。由于采用了实施例二中任一示例所描述的背光装置，本实施例提供的显示装置装配方便、从而可节省成本并缩短开发周期。例如，该显示装置包括广告展示柜、实物展示箱等。

(1)本公开实施例附图中，只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)为了清晰起见，在用于描述本公开的实施例的附图中，层或微结构的厚度和尺寸被放大。
(3)在不冲突的情况下，本公开同一实施例及不同实施例中的特征可以相互组合。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
