Description

侧入式LED灯的背光结构及LED灯
技术领域
本公开涉及照明领域,尤其涉及一种侧入式LED灯的背光结构及LED灯。
背景技术
液晶显示设备已是平板显示领域的主流。由于液晶显示屏本身不发光,因此,需要背光源模组提供足够亮度与分布均匀的光源,使其能正常显示影像。相关技术中,液晶显示设备的背光源主要是LED(Light Emitting Diode;发光二极管)。
针对LED背光源,从背光源结构上分类,一般有直下式和侧光式两种结构。其中,直下式发光方式的缺点是:为了保证均匀出光的效果,就需要保证灯珠到灯罩之间的距离,所以灯的厚度较厚,不符合近年来流行的超薄超轻的审美观。侧光式发光方式的缺点是:结构层数太多,光线过于集中,中心区域照度高,边缘区域照度弱,光损失严重,因此,灯具的光效很低;照度均匀度非常差,会造成眩光;而市场上只采用反光片、导光板和扩散片三层结构的灯具,灯罩发光表面会有颗粒状的亮斑。
发明内容
为克服相关技术中存在的问题,本公开提供一种侧入式LED灯的背光结构及LED灯。
根据本公开实施例的第一方面,提供一种LED灯的背光结构,包括:
反射片;
导光板,布设于所述反射片上;
增光片,布设于所述导光板上;以及
扩散片,布设于所述增光片上。
可选地,还包括:
网点,设于所述导光板上,且位于所述导光板与所述反射片与之间。
可选地,所述网点呈矩阵排列于所述导光板上。
根据本公开实施例的第二方面,提供一种LED灯,包括:
上述的LED灯的背光结构;以及
灯珠,围设于所述导光板的侧面。
可选地,还包括:灯罩边框,围设于所述灯珠的外侧,所述灯珠与所述灯罩边框之间的距离小于预设值。
可选地,所述灯珠贴靠于所述灯罩边框。
可选地,还包括:灯板,设于所述灯罩边框与所述灯珠之间,所述灯珠排列设于所述灯板上。
可选地,还包括:驱动芯片,电连接于所述灯珠。
可选地,还包括:电源,电连接于所述驱动芯片。
可选地,所述灯珠为3014灯珠。
本公开的实施例提供的技术方案可以包括以下有益效果:
1)通过在反射片、导光板和扩散片的基础上增加增光片,当一部分光穿过导光板到达反射片上,这部分光会被反射片反射回导光板,经过导光板到达增光片,经过增光片后进行折射,折射后的角度会大于输入角度,穿过增光片后的光进入了扩散片后,其中的一部分直接从扩散片中射出,另一部分光反射后进入增光片,然后从增光片进入导光板,然后到达反射片,接着再重复以上过程,由于光在本公开的结构中,经过不断的反射和折射,灯罩上的光就变得越来越均匀,使得在灯头部分超薄的情况,照度均匀度也可以满足AA级的要求。
2)本公开中的灯珠可以选择封装非常小的灯珠,比如3014灯珠,可以使得整个灯头结构变得非常薄,符合现代灯具越来越薄的发展趋势;并且灯珠与灯罩边框的距离可以非常近,比如将灯珠贴靠于灯罩边框,从而满足灯罩发光表面无灯珠亮斑。
应当理解的是,以上的一般描述和后文的细节描述仅是示例性和解释性的,并不能限制本公开。
附图说明
此处的附图被并入说明书中并构成本说明书的一部分,示出了符合本公开的实施例,并与说明书一起用于解释本公开的原理。
图1是根据一示例性实施例示出的一种LED灯的背光结构的侧剖图。
图2是根据一示例性实施例示出的一种LED灯的背光结构的另一侧剖图。
图3是根据一示例性实施例示出的一种LED灯的侧剖图。
图4是根据一示例性实施例示出的一种LED灯的背光结构的光线走向图。
具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种LED灯的背光结构的侧剖图,如图1所示,所述LED灯的背光结构10包括反射片11、导光板12、增光片13以及扩散片14。
如图1所示,所述反射片11置于整个背光结构10的最底层,当光线到达所述反射片11的上表面时,所述光线会向上反射回去。即所述反射片11为可以反射光线的材料,比如在所述反射片11的上表面可以涂有反射光线的反射涂层。反射片11的用途在于将从导光板12底面露出的光反射回导光板12中,用来提高光的使用效率低。
继续参照图1,在所述反射片11上布设有导光板12,即在所述反射片11中具有反射面的上方设有所述导光板12。导光板12可以为将线光源转变为面光源的光学级的亚克力板材,由于光学级的亚克力板材具有极高反射率且不吸光的特性,当一部分光穿过导光板12的背光面到达反射片11上,这部分光会被反射片11反射回导光板12,使得被导光板12吸收的光能够从导光板12的出光面逃离所述导光板12。
如图1所示,在所述导光板12上布设有增光片13,部分光从所述导光板12的出光面逃离所述导光板12后,进入所述增光片13,所述增光片13能够提高这部分光的正面亮度,并且这部分光在经过增光片13后进行折射,折射后的角度会大于输入角度,起到了散光的作用;而相关技术中电视机中的增光片13是用于聚光。
继续参照图1,在所述增光片13上布设有扩散片14,部分光在增光片13内经过折射后,进入所述扩散片14,其中有一部分光射出扩散片14,另一部分光反射回增光片13。
接下来,对光线在本公开结构内的走向作一整体的描述,请参照图4,图4是根据一示例性实施例示出的一种LED灯的背光结构的光线走向图,在所述导光板12的侧面增设光源,如图4中的灯珠21。如图4所示,所述灯珠21发出的一部分光穿过导光板12到达反射片11上,这部分光会被反射片11反射回导光板12,经过导光板12到达增光片13,经过增光片13后进行折射,折射后的角度会大于输入角度,穿过增光片13后的光进入了扩散片14后,其中的一部分直接从扩散片14中射出打到灯罩上,另一部分光反射后进入增光片13,然后从增光片13进入导光板12,然后到达反射片11,接着再重复以上过程,由于光在本公开的结构中,经过不断的反射和折射,灯罩上的光就变得越来越均匀。
可选地,图2是根据一示例性实施例示出的一种LED灯的背光结构的另一侧剖图,如图2所示,所述LED灯的背光结构10除包括反射片11、导光板12、增光片13以及扩散片14外,还包括网点15。
如图2所示,所述网点15设于所述导光板12上,且位于所述导光板12与所述反射片11与之间。所述网点15可以是用激光雕刻、V型十字网格雕刻或者UV网版印刷技术在所述导光板12的底面印上的导光点。当光源发出来的光线进入所述导光板12并射到各个导光点时会反射,反射光会往各个角度扩散。所述网点15可以呈矩阵排列于所述导光板12上;也可以是各种疏密、大小不一的设置,进而使导光板12均匀发光。
请继续参照图4,所述灯珠21发出的一部分光穿过导光板12到达底部的网点15上,因为网点15是高低不平,会将光进一步打散,然后光又被反射回导光板12,然后又进入增光片13,在增光片13内经过折射后,进入扩散片14,其中有一部分光射出扩散片14,一部分光反射回增光片13,然后进入导光板12,到达反射片11,接着再重复以上过程,经过不断的反射和折射,灯罩上的光就变得越来越均匀,从而照度均匀度也可以满足AA级的要求。
图3是根据一示例性实施例示出的一种LED灯的侧剖图。如图3所示,所述LED灯20包括上述的LED灯20的背光结构10以及灯珠21。
如图3所示,所述灯珠21作为光源围设于所述导光板12的侧面。所述灯珠21可以选择封装非常小的灯珠21,比如3014灯珠21,可以使得整个灯头结构变得非常薄,符合现代灯具越来越薄的发展趋势。
如图3所示,所述LED灯20还包括灯罩边框23以及灯罩(图中未示出),所述灯罩覆盖于所述扩散片14。所述灯罩边框23围设于所述灯珠21的外侧,所述灯珠21与所述灯罩边框23之间的距离小于预设值,所述预设值可以是2mm、1.5mm或者1mm等。可选地,所述灯珠21贴靠于所述灯罩边框23。由于灯珠21距离灯罩边框23非常近,进而在所述灯罩上不会有一个个灯珠亮斑。
请继续参照图3,所述LED灯20还可以包括灯板22。所述灯板22设于所述灯罩边框23与所述灯珠21之间,所述灯珠21排列设于所述灯板22上。
可选地,所述LED灯20还可以包括驱动芯片和电源。所述驱动芯片电连接于所述灯珠21,所述电源电连接于所述驱动芯片,所述电源为所述驱动芯片工作提供电能,所述驱动芯片驱动所述灯珠21亮起。
当所述驱动芯片驱动所述灯珠21亮起后,如图4所示,所述灯珠21发出的一部分光穿过导光板12到达反射片11上,这部分光会被反射片11反射回导光板12,经过导光板12到达增光片13,经过增光片13后进行折射,折射后的角度会大于输入角度,穿过增光片13后的光进入了扩散片14后,其中的一部分直接从扩散片14中射出打到灯罩上,另一部分光反射后进入增光片13,然后从增光片13进入导光板12,然后到达反射片11,接着再重复以上过程;而所述灯珠21发出的另一部分光穿过导光板12到达底部的网点15上,因为网点15是高低不平,会将光进一步打散,然后光又被反射回导光板12,然后进入增光片13,在增光片13内经过折射后,进入扩散片14,其中有一部分光射出扩散片14,一部分光反射回增光片13,然后进入导光板12,到达反射片11,接着再重复以上过程,经过不断的反射和折射,灯罩上的光就变得越来越均匀,从而照度均匀度也可以满足AA级的要求。
本领域技术人员在考虑说明书及实践本公开后,将容易想到本公开的其它实施方案。本申请旨在涵盖本公开的任何变型、用途或者适应性变化,这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的,本公开的真正范围和精神由下面的权利要求指出。
应当理解的是,本公开并不局限于上面已经描述并在附图中示出的精确结构,并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利要求来限制。
