Description

一种发光线缆 技术领域
本申请涉及一种发光线缆。
背景技术
目前,市面上已有一些可发光的线缆,如耳机线、数据线等。将线缆制作成附带各种发光效果,使其具有良好的观赏性并具有一定的照明效果,在黑暗环境下能够准确及时找到连接线缆的设备接口。
现有的可发光线缆主要形式有EL、LED加光纤和USB插口处加LED。EL需要升压到110V,具有安全性低、亮度低、功耗大的缺陷;LED加光纤的线缆,由于光纤的光衰大,使远离插口处的线缆亮度差,线缆各段的亮度不均匀,视觉效果差;USB插口处加LED的线缆,由于仅在插口处加装LED,视觉效果差。
发明内容
本申请提供一种安全性能高、亮度高、亮度均匀、功耗低的发光线缆。
根据第一方面,一种实施例中提供一种发光线缆包括:第一导线、第二导线、一个或多个LED倒装芯片;LED倒装芯片的一电极端连接在第一导线上,LED倒装芯片的另一电极端连接在第二导线上。
优选地,所述导线材料为铜Cu。
优选地,LED倒装芯片上覆盖有荧光粉层。
优选地,在第一导线、第二导线、LED倒装芯片构成的成型体上涂覆有可透光保护层。
优选地,所述可透光保护层为绝缘材料。
优选地,所述第一导线以及第二导线在非连接于LED倒装芯片的表面区域都涂覆有绝缘层。
优选地,在导线的轴向方向上,等距离均匀分布有所述LED倒装芯片。
优选地,各个LED倒装芯片均匀分布于导线的各个方向。
优选地,所述发光线缆还设置有用于充电的线路和/或用于数据传输的线路。
优选地,所述线路设置于所述可透光保护层的内部。
依据上述实施例的发光线缆、数据线以及充电线,由于LED倒装芯片作为发光源,使得线缆具有亮度高,功耗低的优点;LED倒装芯片可以采用低压电源驱动,因此安全性能高;另外LED倒装芯片并联连接在两条导线上,并采用电阻率低的铜作为导线材料使各个LED倒装芯片亮度相同,不会产生光衰,线缆各段的亮度更加均匀。进一步,在第一导线、第二导线、LED倒装芯片构成的成型体上涂覆可透光保护层,LED倒装芯片发出的光线经可透光保护层透射,同时也对成型体构成外围保护。
附图说明
图1为线缆一实施例结构示意图;
图2图1A-A剖视图;
图3为线缆另一实施例剖视图。
具体实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。其中不同实施方式中类似元件采用了相关联的类似的元件标号。在以下的实施方式中,很多细节描述是为了使得本申请能被更好的理解。然而,本领域技术人员可以毫不费力的认识到,其中部分特征在不同情况下是可以省略的,或者可以由其他元件、材料、方法所替代。在某些情况下,本申请相关的一些操作并没有在说明书中显示或者描述,这是为了避免本申请的核心部分被过多的描述所淹没,而对于本领域技术人员而言,详细描述这些相关操作并不是必要的,他们根据说明书中的描述以及本领域的一般技术知识即可完整了解相关操作。
另外,说明书中所描述的特点、操作或者特征可以以任意适当的方式结合形成各种实施方式。同时,方法描述中的各步骤或者动作也可以按照本领域技术人员所能显而易见的方式进行顺序调换或调整。因此,说明书和附图中的各种顺序只是为了清楚描述某一个实施例,并不意味 着是必须的顺序,除非另有说明其中某个顺序是必须遵循的。
本文中为部件所编序号本身,例如“第一”、“第二”等,仅用于区分所描述的对象,不具有任何顺序或技术含义。而本申请所说“连接”、“联接”,如无特别说明,均包括直接和间接连接(联接)。
请参考图1和图2,发光线缆10包括第一导线2、第二导线3、多个LED倒装芯片1;LED倒装芯片1一电极端通过连接层4连接在第一导线2上,LED倒装芯片1另一电极端通过连接层4连接在第二导线3上;LED倒装芯片1上覆盖有荧光粉层5。第一导线2和第二导线3通常平行并排设置。在第一导线、第二导线、LED倒装芯片构成的成型体上涂覆有可透光保护层6,对成型体进行封装。其中,可透光保护层优选为绝缘材料。在本申请其它实施例中,为适应特殊应用保持线缆的纤细,也可以不需要保护层。荧光粉层的作用是改变发光颜色,在本申请其它实施例中,LED倒装芯片上也可以不需涂覆荧光粉层。在本申请其它实施例中,在导线上也可以仅设一个倒装芯片。
导线可以采用电阻率低的铜Cu、铝Al或银Ag,使各个LED倒装芯片两端等压,倒装芯片的发光亮度相同。
在实际生产中,将第一个LED倒装芯片的正极端连接在第一导线上,负极端连接在第二导线上,相邻的LED倒装芯片的负极端连接在第一导线上,正极端连接在第二导线上,在驱动电路切换第一、第二导线的正负极的状态下,具有上述发光线缆的产品(如数据线、充电线、耳机)在充电或者传输数据时,整条线缆显示出流动的发光效果。在驱动电路的其它驱动模式下,线缆也可以产生闪动、不闪动、不流动等发光效果。在实际生产中,还可以将第一个和第二个LED倒装芯片作为第一组,将第一组LED倒装芯片的正极端连接在第一导线上,将第一组LED倒装芯片的负极端连接在第二导线上,相邻的第三个和第四个LED倒装芯片作为第二组,将第二组的负极端连接在第一导线上,将第二组的正极端连接在第二导线上,在驱动电路切换第一、第二导线的正负极的状态下,发光线缆显示出流动的发光效果。依次类推,可将相邻的3个LED倒装芯片或4个LED倒装芯片作为一组,形成流动发光效果。
连接层4可以是锡膏或导电胶,通过连接层使LED倒装芯片稳固地固晶在导线上。本案可以对连接层的材料进行改变,只要能实现倒装芯片在导线上固定即可。
第一导线以及第二导线可以采用双并漆包线,将导线上的绝缘层刮掉形成固晶区,倒装芯片固晶在固晶区。即第一导线以及第二导线在非连接于LED倒装芯片的表面区域都涂覆有绝缘层。
在导线的轴向方向上,等距离均匀分布有所述LED倒装芯片。各个LED倒装芯片均匀分布于导线的各个方向。使线缆各段和各个方向亮度更加均匀,增强视觉效果。在其它实施例子,LED倒装芯片的分布也可以不均匀。
请参考图3,为线缆的另一实施例剖视图,其包括第一导线2、第二导线3、LED倒装芯片1;LED倒装芯片1一电极端通过连接层4固晶在第一导线2上,另一电极端通过连接层4固晶在第二导线3上;LED倒装芯片1上覆盖有荧光粉层5。线缆还设置有用于充电的线路7和用于数据传输的线路8,形成数据线、充电线、耳机线等产品。
其中,用于充电的线路7和用于数据传输的线路8设置于所述可透光保护层6的内部。
以上应用了具体个例对本发明进行阐述,只是用于帮助理解本发明,并不用以限制本发明。对于本领域的一般技术人员,依据本发明的思想,可以对上述具体实施方式进行变化。
