Description

一种灯带及线光源 技术领域
本实用新型属于照明设备技术领域，具体涉及一种灯带及线光源。
背景技术
随着社会的不断发展，光源的作用已经不仅仅局限于传统的照明作用了，更多的时候是起到装饰性的作用。其中，LED灯带或灯条就是一种典型的线光源，因为其使用的FPC(柔性电路板)材质柔软，可以任意弯曲、折叠、卷绕或剪切，使其可适用于不规则的地方和空间狭小的地方，例如，由于灯带可以任意的弯曲和卷绕，其适合于在广告牌或展示牌中组合成各种图案(文字、图形)；又如将灯带缠绕在树上、建筑物上以形成造型各异的装饰性光源。
但是现有技术中的线性光源在施工或布置时存在着一定的不便之处，如申请号为202120086507.9的实用新型专利中所公开的一种低压的具有倒装LED芯片的柔材性灯带。具体来说，为了方便灯带在施工过程中的灵活布置，即不需要预先计算灯带的长短，因此在沿灯带(柔性电路板)的长度方向上设置了多个接线位，同时在接线位处设置剪切标识线，进而使得施工人员可以根据需求对灯带进行随用随剪；进一步的，当灯带的裁剪完成后，在灯带的接线位上接上电源线即可。然而，在现有技术的灯带中，接线位与电源线的连接主要是通过钎焊(锡焊)的方式来形成连接的，而为了便于钎焊的顺利进行，则需要套在灯带的表皮(外套皮)剥除一部分，以充分暴露出接线位；另外，还需要将灯带和电源线进行固定后才能顺利进行焊接作业；再者，对灯带与电源线进行钎焊时还需要准备钎焊设备才能实施焊接工作。因此，使得灯带在布置或施工过程中产生了如上所述的不便。

相对于现有技术本实用新型的有益效果主要体现在：通过在灯带上设置接线位，同时在部分接线位上设置插口，也就是说，线光源在施工或布置过程中需要接线时，只需要通过插接件(插接件预先与电源连接线形成连接，或者说预制)则可快速且便捷的使电源线与灯带形成导通或者说形成电连接，进而提高了线光源在施工或布置过程中的便捷性；进一步的来说，当不需要使用插口与电源线形成连接时，此时，则可以接直通过接线位与电源线形成电连接(传统的钎焊连接方式)，从而提高了线光源的适用性，即，使得线光源可以适用于不同的接线需求。

具体实施方式
下面结合附图和具体实施例对本实用新型技术方案作进一步的详细描述，以使本领域的技术人员可以更好的理解本实用新型并能予以实施，但所举实施例不作为对本实用新型的限定，在本实施例中，需要理解的是，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限定。
需要说明的是，当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件并与之结合为一体，或者可能同时存在居中元件。本实用新型中所使用的术语“安装”、“一端”、“另一端”以及类似的表述只是为了说明的目的。
如图1-9所示，本实施例提供了一种灯带1，其包括柔性的电路板3、多个灯珠4和多个插口5，柔性电路板3是指以聚酰亚胺或聚酯薄膜为基材制成的一种具有可挠性电路板；灯珠4沿电路板3的长度方向间隔排列，且灯珠4与电路板3以钎焊(锡焊)的方式形成电连接，电路板3上还设置有多个接线位6，每个接线位6与一个或者多个灯珠4电连接，即，通过接线位6引入电源并为电路板3上的灯珠4进行供电，接线位6沿电路板3的长度方向间隔排列，每个插口5与对应的接线位6通过钎焊形成电连接，或者说，插口5与部分接线位6形成电连接，插口5用于与导线16插接连接。进一步来说，通过在灯带1上设置接线位6，同时在接线位6上设置插口5，当线光源在施工或布置过程中需要接线进而为灯带1或者说线光源进行供电时，只需要通过插接件(插接件可以预先与短的电源连接线形成连接，或者说预制)则可快速且便捷的使导线与灯带1形成导通或者说形成电连接；进一步，当不需要使用插口5与导线形成连接时，此时，则可以接直通过接线位6与导线形成电连接(传统的钎焊连接方式)，从而提高了线光源在施工或布置过程中的适用性，即，使得线光源可以适用于不同的接线需求。
如图2、3、5所示，在优选实施例中，插口5的插接方向沿电路板3的长度方向或者沿电路板3的宽度方向，即，插口5的轴线与电路板3轴线相平行， 或者，插口5的轴线与电路板3的轴线形成夹角，如形成90度的夹角。进一步的，插口5沿电路板3的长度方向贯通，且插口5可沿电路板3的长度方向双向插接，或者，可相对于电路板3的宽度方向双向插接；从而进一步提高灯带1与导线插接的便捷性。
如图8所述，在优选实施例中，多个接线位6沿电路板3的长度方向呈两列多行设置，相邻两行接线位6之间设置一个、两个、者三个灯珠4、六个灯珠4或更多个灯珠4，三行及以上的接线位6均与对应的插口5通过焊接形成电连接。具体来说，在实施例中，插口5与接线位6(或者说焊盘)一一对应，也就是说，不用考虑留出空置的接线位6以便于进行传统的钎焊方式进行接线，即，只考虑灯带在进行接线时以插接方式进行连接。相邻两行接线位6之间的灯珠4数量可以根据不同的施工需求进行选择，例如，在施工过程中当灯带需要频繁剪切时，此时则可以选择相邻两行接线位6之间的灯珠4数量相对较少的灯带，以减少因为剪切而造成灯带用料上的浪费；同理，当灯带在施工过程中不需要频繁剪切时，此时则可以选择相邻两行接线位6之间的灯珠4数量相对较多的灯带，以减少设置接线位6以及插口5的量，进而达到减少灯带使用成本的目的。
进一步来说，由于灯带1或者说线光源在使用过程中根据其实际使用情况而进行灵活的剪切，且剪切后的单根灯带1的长度也不会很短，也就是说对于线光源的具体剪切长度或者剪切点并不需要很高的精度；因此，相对于灯带1的长度方向，适当的增大插口5的间隔距离，即，三行及以上的接线位6均与对应的插口5电连接，从而可以有效减少线光源在生产制作时对于插口5数量的消耗或者说控制，进而减少线光源的生产成本。例如，在布置线光源的过程中，在线光源上即将剪断的位置处并没有插口5，此时，则可以沿着灯带15进行延伸直到定位到灯带1上具有插口5的集中区7时再对线光源进行剪断；也就是说，线光源因为剪切而增加延长部分产生的成本，相对于将插口5焊接在每一个接线位6上来说相对要低。进一步来说，本说明书中所指的一个插口5指的是一组插口5，即，两列，也就是说，一组插口5中包括分连接电源正极和负极的两个独立的插口5。
如图6所示，在优选实施例中，插口5呈两开口的管状，插口5上还设置有连接端51，连接端51用于使插口5与接线位6形成连接，且插口5的内壁上设置有凸缘52，凸缘52用于插入的导线16形上的插头17成卡持固定；和/或，相对于插口5的截面，连接端51呈波浪状起伏，连接端51呈波浪状可以使得插口5与接线位6进行钎焊时更好的上锡，即，使得插口5与电路板3形成更好的固定。
如图3所示，在优选实施例中，电路板3上背向灯珠4的表面还设置有剪切标记线8，剪切标记线8分别与接线位6和/或插口5相对应。进一步的，相对于电路板3的宽度方向，剪切标记线8由电路板3的一端延伸至另一端。当需要对灯带1进行剪切时，剪切标记线8可以提供切剪参照，即，沿着剪切标记线8剪断灯带1后，灯带1上的剪断处能使与电路板3上的接线位6或插口5相对应，进而便于接下来灯带1与导线16的连接，或者说便于灯带1剪切后的接线。进一步的，沿着剪切标记线8剪断灯带1后，电路板3上断口处皆有被剪断的接线位6残余的部分(例如，剪切标记线8位于接线位6长度方向的中部)，或者，沿着剪切标记线8剪断灯带1后，电路板3上断口的一侧为被剪断的接线位6残余的部分，另一侧则为插口5，当然，插口5焊接在被剪断的另一残余的接线位6上。进一步的，与接线位6相对应的剪切标记线8的宽度小于与插口5相对应的剪切标记线8的宽度；或者，与插口5相对应的剪切标记线8的宽度小于与接线位6相对应的剪切标记线8的宽度；设置不同宽度的剪切标记线8后，有助于在对线光源进行剪切时可以有效区分出哪些为接线位6，哪些为插口5。例如，当需要插接的方式使灯带1与电源进行连接时，则可以沿着粗的剪切标记线8进行剪切。
如图1、5、6、7、9本实施例还提供了一种线光源，其包括柔性的护套2以及如上所述的灯带1，护套2套设在灯带1外，且护套2至少有部分材料为透光材料；护套2可以对灯带1形成保护，例如，在雨水天气时，护套2可以避免灯带1处于潮湿的环境中而造成灯带1的损坏。进一步的，该线光源还包括有端盖9和引出导线16，护套2的端部开口，即，护套2的剪断处形成开口，且护套2端部的电路板3上设置有插口5，引出导线16端部设置有插头17，插 头17插入插口5中并固定进而与电路板3电连接，其中，插头17上设置有与凸缘52相互配合的凹陷部18，当然，该凹陷部18也可以为通孔，当插头17插到插口5中，凸缘52卡入于凹陷部18中，进而使得插头17与插口5形成固定。
如图4-5所示，在优选实施例中，端盖9通过胶粘连接在护套2的端部并对护套2的端部进行封闭，引出导线16相对于护套2折弯，并部分嵌入端盖9中。本实施例中的封盖呈U形，且相对于端盖9的长度方向，端盖9的一端封闭，另一端开放端；进一步来说，当线光源的末端完成导线的连接以后，将导线相对于护套2的轴线弯折90度，然后将端盖9通过粘胶连接在线光源的端部，即，导线从端盖9的开放端引出。端盖9可以避免水进入到护套2内而造成灯带1的故障，或者可以避免异物如灰尘进入到护套2内而影响线光源的发光效果。进一步的，位于护套2中部的电路板3上也设置有插口5，即，用于连接外部导线的插口5并不只限于护套2的端部，即剪断处，也就是剪断后的灯带或者说线光源也可以根据实际使用需求再次进行长度上的剪切。
如图2-3所示，在优选实施例中，电路板3上设置有多个集中区7，插口5皆设置在集中区7内，且每个集中区7内设置有一个或多个插口5，集中区7沿电路板3的长度方向排列，且彼此相邻的两个集中区7间隔预设距离。其中，彼此相邻的两个集中区7的间隔距离为30-150CM，又如40、50、60、70、80、90、100、110、120、130、140CM。进一步来说，由于线光源在使用过程中根据其实际使用情况而进行灵活的剪切，且剪切后的单根线光源的长度也不会很短，也就是说对于线光源的具体剪切长度或者剪切点并不需要很高的精度；因此，将插口5设置在集中区7内且两个相邻的集中区间隔相应的距离，可以有效减少线光源在生产制作时对于插口5数量的消耗或者说控制，进而减少线光源的生产成本。举例来说，在布置线光源的过程中，在线光源上即将剪断的位置处并没有插口5，此时，则可以沿着灯带15进行延伸直到定位到灯带1上具有插口5的集中区7时再对线光源进行剪断；也就是说，线光源因为剪切而增加延长部分产生的成本，相对于将插口5焊接在每一个接线位6上来说相对要低。进一步来说，本说明书中所指的一个插口5指的是一组插口5，即一组插口5中包括分连接电源正极和负极的两个独立的插口5。本实施例中的灯珠4为LED灯 珠4。
如图4-5所示，在优选实施例中，还包括有端盖9，端盖9连接在护套2的末端并对护套2的末端进行封闭，本实施例中的封盖呈U形，且相对于端盖9的长度方向，端盖9的一端封闭，另一端开放端；进一步来说，当线光源的末端完成导线的连接以后，将导线相对于护套2的轴线弯折90度，然后将端盖9通过粘胶连接在线光源的端部，即，导线从端盖9的开放端引出。当然，端盖9也可以是如图的帽状，该端盖9的截面与护套2的截面形状一致，进一步的，此时的端盖9上同时也会开设有通孔，用于穿出连接灯带1的导线。端盖9可以避免水进入到护套2内而造成灯带1的故障，或者可以避免异物如灰尘进入到护套2内而影响线光源的发光效果。
如图1所示，在优选实施例中，护套2由透光材料制成，灯带1发出的光透过护套2对外发光。
如图1、9所示，在优选实施例中，护套2上还包括有遮光部10，遮光部10上设置有开口，护套2部分嵌于遮光部10内，且护套2封闭遮光部10的开口并在开口处形成出光面11，灯带1发出的光穿过出光面11对外发光。进一步来说，本实施例中的遮光部10呈U型，设置的遮光部10可以实对护套2的出光面11进行部分遮挡或者说实现自发光线光源照射的指向性，从而满足不同的使用需求。本实施例中的护套2以及遮光部10皆为柔性材料，且护套2和遮光部10为硅胶或PVC中的一种或组合。
如图1、9所示，在优选实施例中，遮光部10沿其长度方向上还设置有指示窗12，指示窗12与遮光部10和护套2一体成型，指示窗12与灯带1的背面相对，指示窗12与剪切标记线88相对并用于显示剪切标记线88；进一步的，当不设置遮光部10时，也就可以不需要设置指示窗12。进一步来说，电路板3上还设置有剪切标记线88，剪切标记线88分别与接线位6和/或插口5相对应。进一步的，与接线位6相对应的剪切标记线88的宽度小于与插口5相对应的剪切标记线88的宽度；或者，与插口5相对应的剪切标记线88的宽度小于与接线位6相对应的剪切标记线88的宽度；设置不同宽度的剪切标记线88后，有助于在对线光源进行剪切时，可以快速区分并定位到灯带1上与插口5相对应 的区域，即，便于线光源剪切后的快速接线。
本实施例中的剪切标记线88设置在接线位6长度方向的中部。线光源在生产成型后每一根往往具有数十米的长度，用户根据不同的使用需求可以将自发光线光源剪切成不同的长度，例如剪成一米、五米或十米等长度；其中，剪切标记线8沿着灯带1中电路板3的长度方向进行间隔设置，例如，在基板上每间隔1CM、2CM、3CM、5CM、10CM等距离便印刷标注一个剪切标记线88，从而便于用户的准确剪切，进一步来说，设置了剪切标记线88以后，并且在剪切标记线8处的接线位6(相当于焊盘)上进行接线。
如图1所示，在优选实施例中，护套2内还设置有抗拉带13，抗拉带13由透明的柔性材料制成。本实施例中的抗拉带13为透明塑料制成，透明的抗拉带13以避免对灯带1上的剪切标记线88造成阻挡；其次，抗拉带13用于增强线光源的抗拉强度，避免或减少线性光线在受到拉力时灯带1的电路板3因为受到拉力而受到损伤或损坏，如造成灯带1发光不良或是不能发光。
如图1所示，在优选实施例中，护套2内设置有空腔14，灯带1置于空腔14内，且空腔14中还设置有限位槽15，灯带1卡持于限位槽15内；设置的限位槽15可以使得灯带1相对于护套2的位置保持一致性，避免线光源因为弯折或缠绕而造成灯带1相在空腔14内发生扭曲进而对发光效果造成影响。进一步来说，设置的空腔14除了可以减少护套2在生产时对原材料的消耗外；另外灯带1中的灯珠4在工作时也会产生一定的热量，且灯带1上的灯珠4之间间隔一定的距离，而设置的空腔14有助于空腔14内空气的高低温区的相互对流，即靠近灯珠4的区域的空气温度会高一些，而远离灯珠4区域的空气温度则会相对低一些，进而有助于灯带1的散热。
相对于现有技术本实用新型的有益效果主要体现在：通过在灯带上设置接线位，同时在部分接线位上设置插口，也就是说，线光源在施工或布置过程中需要接线时，只需要通过插接件(插接件可以预先与短的电源连接线形成连接，或者说预制)则可快速且便捷的使电源线与灯带形成导通或者说形成电连接，进而提高了线光源在施工或布置过程中的便捷性；进一步的来说，当不需要使用插口与电源线形成连接时，此时，则可以接直通过接线位与电源线形成电连 接(传统的钎焊连接方式)，从而提高了线光源的适用性，即，使得线光源可以适用于不同的接线需求。
