Description

一种带自成型LED光源的灯泡 技术领域
本发明涉及照明灯具领域,尤其涉及一种带自成型LED光源的灯泡,属于LED照明技术领域。
背景技术
LED光源由于发光亮度足、发光均匀,且耗电量少,堪称绿色能源,因此已经逐步取代了使用达百年之久的钨丝灯,随着照明科技的进一步发展,LED光源从点光源逐渐变成条状光源,甚至是多种形状的长条状柔性灯丝;LED柔性灯丝可在同样面积的情况下,瓦数增加多倍甚至数倍,具备很强的实用性,这是传统的条状LED灯条所无法企及的;目前较为常见的为螺旋状LED柔性灯丝,其结构美观,发光瓦数大。但是在实际使用中也发现,由于螺旋灯丝为柔性灯丝,在安装到灯泡内以后,需要支撑结构来固定其在灯泡内的位置,目前较为常见的为横向、竖向、斜向的玻璃灯芯柱支撑结构,以及固定于玻璃灯芯柱上的金属连接丝(如钨丝),两者相结合用于固定柔性灯丝,从而导致灯泡内部结构过于复杂,并且安装工艺复杂,安装成本增加,加工效率降低。
伴随着瓦数的增加,另外一个问题也随之而来---即散热的问题,目前LED灯泡的散热通常采用两种方式,一种是加入散热气体,一种是安装导热管达到散热的目的,如浙江锐迪生光电有限公司在2012年月12日申请的专利号为201210063705.9(一种LED灯泡)的专利中,就阐述了“LED发光源由至少一个透明LED发光柱组成;LED发光柱包括:插于支柱外表面 的高导热率透明管”;两种方式中,前者导致加工工艺复杂化,后者导致结构复杂化,进而导致成本增加。
发明内容
本发明就是针对上述问题,提出一种带自成型LED光源的灯泡,该灯泡内的LED光源无须支撑结构,从而使结构更趋简单化,并且加工成本低,加工效率高,同时具有较好的散热性能。
为达到上述目的,本发明提出了一种带自成型LED光源的灯泡,包括一透明或局部透明的玻璃制成的、任意形状的、内部充气或不充气的灯泡壳,所述灯泡壳后端设有电源驱动,所述电源驱动两端设有电源正极电杆和电源负极电杆,还包括一以横向、竖向或斜向设置于灯泡壳内的自成型LED光源,所述自成型LED光源两端分别设有电源正极和负极,所述电源正极和负极分别和电源正极电杆、电源负极电杆形成电性连接。
作为本发明之优选,所述自成型LED光源包括一透明或非透明柔性基板,所述柔性基板的正面、反面或正反面同时贴覆有一层导电层,所述导电层刻蚀线路,并在线路上固定有若干倒装LED芯片,并且在倒装LED芯片上涂覆有荧光胶体或透明胶体。
作为本发明之优选,所述自成型LED光源包括任意形状的弧形、螺旋型自成型结构、任意形状的锐角、钝角形状自成型结构,以及上述三者相结合的自成型结构。
作为本发明进一步的优选,所述自成型LED光源为自成型LED柔性灯丝,该自成型LED柔性灯丝为同心圆或非同心圆螺旋结构的LED柔性灯丝,所述同心圆螺旋结构的LED螺旋灯丝的直径在5-80mm之间,各个螺旋间距在3-35mm之间。
作为本发明进一步的优选,所述自成型LED柔性灯丝为V型或W型或波浪型结构的LED柔性灯丝。

具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细地说明。
由图1可知,一种带自成型LED光源的灯泡,包括一透明或局部透明的玻璃制成的、任意形状的、内部充气或不充气的灯泡壳1,该灯泡壳1后端设有电源驱动2,在电源驱动2两端设有电源正极电杆3和电源负极电杆4,同时还包括一以横向、竖向或斜向设置于灯泡壳内的自成型LED光 源,该自成型LED光源两端分别设有电源正极和负极,电源正极和负极分别和电源正极电杆3、电源负极电杆4形成电性连接,所谓的电性连接,是指任意方式形成的电性连接,如焊接,穿孔连接,铆接等等。
由图2和图3可知,在本发明中,优选的自成型LED光源包括一透明或非透明柔性基板6,该柔性基板6的正面、反面或正反面同时贴覆有一层导电层9,在导电层9上固定有若干倒装LED芯片8,并且在倒装LED芯片8上涂覆有荧光胶体10或透明胶体,柔性基板6正面贴覆导电层9、固定倒装LED芯片8即形成单面发光;柔性基板6双面贴覆导电层9、固定倒装LED芯片8即形成双面发光。
在本发明之中,优选的自成型LED光源包括任意形状的弧形、螺旋型自成型结构、任意形状的锐角、钝角形状自成型结构,以及上述三者相结合的自成型结构。
比如,该自成型LED光源为自成型LED柔性灯丝5,该自成型LED柔性灯丝5为同心圆自成型灯丝21(见图6)或非同心圆自成型灯丝12(见图5),实际应用当中,同心圆螺旋结构的LED螺旋灯丝的直径在5-80mm之间,各个螺旋间距在3-35mm之间。
由图4可知,作为本发明进一步的优选,所述自成型LED柔性灯丝为V型自成型灯丝或W型自成型灯丝11或波浪型结构的LED柔性灯丝。
作为本发明进一步的优选,一根或多根同心圆或非同心圆自成型灯丝12、或V型或W型或波浪型结构的LED柔性灯丝与灯泡壳1的内壁相接触,或自成型LED柔性灯丝5与灯泡壳1的内壁之间留有一定的间隙,所谓的留有一定的间隙,是指两者之间存在一定的距离。
本发明的自成型LED柔性灯丝5的正面或背面或双面通过单荧光粉、 特殊荧光粉,实现多种颜色的自成型LED柔性灯丝5,如绿色自成型LED柔性灯丝、红色自成型LED柔性灯丝、紫色自成型LED柔性灯丝;或者是每个LED芯片涂覆荧光层,具体为:白光1000K--3000K和5000K--7000K单独涂覆荧光粉层的芯片进行有序间隔分布,从而实现不同颜色的组合,比如设定100颗芯片,其中任意两颗芯片之间所发的光的颜色不同,如一颗为红色,间隔一颗为绿色。
由图9可知,在本发明中,自成型LED光源包括一个或多个截面形状呈椭圆、矩形的LED柔性灯片16,该LED柔性灯片16两端设有光源正极17和光源负极18,且一个或多个LED柔性灯片16以弯曲或平直或螺旋的形状,通过电源正极17、光电源负极18和电源正极电杆3和电源负极电杆4形成电性连接。
该LED柔性灯片16的数量为一片或一片以上,且所述一片或一片以上的LED柔性灯片16以平行、立体交叉、V型(见图10)、W型或上述任意组合结构,通过每一片LED柔性灯片16的电源正极17、电源负极18和电源正极电杆3、光电源负极电杆4形成电性连接。
由图7和图8可知,本发明还公开了一种带自成型LED光源的灯泡,包括一自带电源的自成型LED光源以及一透明或局部透明的玻璃制成的、任意形状的、内部充气或不充气的灯泡壳1,所述光源的正负极分别与灯头的火线、零线相连接;同时,带电源的自成型LED光源包括一金属或非金属柔性基板6,该柔性基板6的正面、背面或正反面同时布置有线路、电源驱动部件13及倒装LED芯片8,同时在线路、电源驱动部件13及倒装LED芯片8上涂覆有荧光胶体10或透明胶体。
当然,实际应用中,自带电源的自成型LED光源和上文所说的自成型 LED光源的唯一区别在于是否自带电源,其他结构都是相同的,因此,无论是自成型灯丝(自带电源或不带电源)或自成型灯片(自带电源或不带电源)都可以以上文所说的各种形状出现。
图11和15所呈现的,是本发明中自带电源或不带电源的自成型LED光源的另一种应用,该应用中,柔性基板6通过可折叠的折叠槽20形成一块折叠基板19以及折叠覆盖板22,在折叠基板19正面贴覆有一倒装线路7,在倒装线路7上固定有若干倒装LED芯片8(见图12),并且在倒装LED芯片8上涂覆有荧光胶体10或透明胶体(图11),形成侧面、顶端均能发光的发光光源(图13),然后将折叠基板19通过折叠槽20折叠成多种形状,折叠完成后,最后将折叠覆盖板22进行折叠覆盖(折叠覆盖板22可以是一个、两个或多个,详细请看图11和图15),即可成为一个无内部支撑柱的柔性LED光源,如本发明中的六边形形状(见图14),图16中,我们可以看到,折叠基板19折叠成六面形结构,在其外侧设置LED发光芯片及荧光层,以及在折叠覆盖板22上设置LED发光芯片及荧光层,最后运用于泡壳灯上的结构。
当然,实际应用中折叠基板19的形状应不限于图11或图16的形状,还可以是其他多种形状,比如圆形,梯形等等。
本发明还公开了制作自成型LED光源的一种模具(见图17),该模具包括基座14和凹槽15,凹槽15可根据需要的自成型LED光源的形状进行定做。
当然,制作自成型LED光源也可以采用裁切的方式获得,如,事先将裁切刀设计成曲面型,则裁切出来的灯片或灯丝也是相应的曲面型。
总的来说,本发明采用自成型结构的LED柔性灯丝或灯片作为光源, 省掉了灯泡内原本用于支撑LED柔性灯丝的支撑结构,从而大大简化了灯泡内部结构,提高了加工效率,减少了制造成本;同时,采用柔性灯丝或灯片贴设于灯泡内壁的结构,将灯泡泡壳自身的散热性能达到最优化,从而增加了灯泡整体的散热性能。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明的技术原理的前提下,还可以做出若干改进和变型,这些改进和变型也应视为本发明的保护范围。
