具体实施方式
为使本申请的目的、技术方案及优点更加清楚、明确,以下参照附图并举实施例对本申请进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
在GB_T 20145-2006灯和灯系统的光生物安全性国家标准文件中,给出了不同波段光源对视网膜危害的光谱加权函数表,从该标准文件中可以看出,420-460nm波段对人眼伤害加权因子最大。目前背光源LED灯珠普遍采用蓝光芯片中心波长在445-460nm左右,且由于LED蓝光波段存在的半波宽,其在420-460nm波段有着相当部分的蓝光存在,因此对人眼的伤害很大。虽然目前手机和TV上普遍采用防蓝光模式或护眼模式的软件模式来达到降低蓝光目的,但只能对蓝光进行总体能量降低,无法对420-460nm短波蓝光进行过滤。为了解决上述问题,本申请提供了一种背光源模组,如图2中所示,所述背光源模组,包括:背板(背板中设置有反射片),背板中设置有腔体22,设置在所述腔体22内的LED灯条21;设置在所述腔体22上方的扩散板23;以及设置在所述扩散板23上的光学膜片24;其中,所述背光源模组还包括有用于对短波蓝光吸收的短波蓝光吸收剂15(图1中所示);所述短波蓝光吸收剂15封装于所述LED灯条21内或者涂布于所述光学膜片24(光学膜片24设置有多层)上。
本申请通过设置短波蓝光吸收剂15对短波蓝光进行吸收,短波蓝光吸收剂15可以设置在LED灯条21内或者设置在光学膜片24上,通过设置的短波蓝光吸收剂15来降低短波蓝光的比例,从而降低对人眼的伤害。
具体地,如图1中所示,所述LED灯条21包括LED发光芯片11;包覆于所述LED发光芯片11上的用于将所述LED发光芯片11发出的光转化成白光的 光学转化层12;以及设置在所述光学转化层12上的短波蓝光吸收层13。当所述短波蓝光吸收剂封装于所述LED灯条内时,所述短波蓝光吸收层13中设置有短波蓝光吸收剂15。
进一步地,本申请中的所述LED发光芯片11可以为蓝光芯片,也可以为蓝光芯片和绿光芯片两种芯片,也可以为蓝光芯片和绿光芯片及红光芯片三种芯片。蓝光芯片,绿光芯片和红光芯片中心波长分别为440-470nm,520-550nm,620-650nm。当所述LED发光芯片11为蓝光芯片时,所述光学转化层12中包括有粒子14,所述粒子14为黄光荧光粉,或者绿光与红光荧光粉的组合,或者绿光与红光量子点的组合。当所述LED发光芯片11为蓝光芯片与绿光芯片的组合时,所述光学转化层12中的粒子14为有红光荧光粉或者红光量子点。当所述LED发光芯片11为蓝光芯片、绿光芯片及红光芯片的组合时,所述光学转化层12无需设置,因为蓝、绿、红三种芯片无需转化层即可组合成白光。
优选地,本实施例中,所述黄光荧光粉优选YAG粉,绿光与红光荧光粉为硅酸盐或氟化物或氮化物荧光粉,绿光荧光粉优选β-塞隆绿粉,红光荧光粉优选KSF荧光粉,量子点优选硒化镉量子点材料,当然,光学转化层12中还包括LED常用的封装胶体。所述短波蓝光吸收层13中还设置有光稳定剂16。较佳地,所述蓝光吸收剂15包括有机蓝光吸收剂及有机无机杂化蓝光吸收剂一种或几种,有机蓝光吸收剂包括酚类有机蓝光吸收剂、胺类有机蓝光吸收剂或三唑类有机蓝光吸收剂;所述有机无机杂化蓝光吸收剂为镍类有机无机杂化蓝光吸收剂。
当所述短波蓝光吸收剂涂布于所述光学膜片上时,所述短波蓝光吸收剂涂布于所述光学膜片的上部或者下部,具体地,本申请提供一种应用该涂布有短波蓝光吸收剂的光学膜片的实施例,如图3中所示。图3在直下式背光源模组中的应用示例,当然,具有该短波蓝光吸收剂的膜片亦可应用于侧入式背光源模组中。图3中背光源模组同样包括背板(背板中设置有反射片),所述背板中设置有腔体32,设置在所述腔体32内的LED灯条31;设置在所述腔体32上方的扩散板33;以及设置在所述扩散板33上的光学膜片34和35(光学膜片设置有多层,图3中用34和35表示)。在此实施例中,所述光学膜片34或者光学膜片35上涂布有短波蓝光吸收剂(图3中为标出),使得光学膜片34或者35具有吸收短波蓝光的功能,从而降低短波蓝光对人眼的伤害。
较佳地,所述光学膜片34或者35包括扩散片、增亮片、DBEF、复合膜片的一种或者多种组合。当背光源模组方案采用量子点膜片方案时,为了保证蓝光对红、绿量子点的激发效率,本实施例将含有短波蓝光吸收剂粒子的光学膜片置于最上层,即图3中光学膜片35;若为除量子点膜片的其他背光方案,含有短波蓝光吸收剂粒子的光学膜片优先置于底层,即图3中的光学膜片34。
进一步地,本申请还提供不同的背光方案中的蓝光光谱图,如图4中所示,图4中有是三种不同背光方案的蓝光光谱,这三中方案分别为:采用普通YAG-LED的背光源模组、具有本申请的短波蓝光吸收剂的背光源模组以及采用软件降低蓝光总量的背光源模组。本实施例中以v=(420-460nm短波蓝光)/(400-500nm总蓝光)作为因子评判短波蓝光所占总蓝光的比例,得到如表1所示结果。
TV方案 v
普通YAG-LED背光方案 0.72
短波蓝光吸收剂粒子应用背光方案 0.65
软件降低蓝光方案 0.70
表1
由表1结合图4可知,采用软件降低蓝光总量的背光源模组中,并未将短波蓝光所占总体蓝光比例大幅降低,而具有本申请的短波蓝光吸收剂的背光源模组方案,可大幅降低短波蓝光所占比例,保护人眼健康。
综上所述,本申请提供的一种背光源模组,包括:腔体,设置在所述腔体内的LED灯条;设置在所述腔体上方的扩散板;以及设置在所述扩散板上的光学膜片;其中,所述背光源模组还包括有用于对短波蓝光吸收的短波蓝光吸收剂;所述短波蓝光吸收剂封装于所述LED灯条内或者涂布于所述光学膜片上。本申请通过在LED灯条中封装短波蓝光吸收剂或者在光学膜片上涂布短波蓝光吸收剂,用于对短波蓝光进行吸收,以降低短波蓝光比例,从而降低短波蓝光对人眼的伤害。
应当理解的是,本申请的应用不限于上述的举例,对本领域普通技术人员来说,可以根据上述说明加以改进或变换,所有这些改进和变换都应属于本申请所附权利要求的保护范围。
