Description

一种灯丝 技术领域
本实用新型涉及灯丝的结构。 背景技术
灯丝发光的原理是令电流通过灯丝产生电阻热， 热量在灯丝绕成螺旋 的发光段产生热能聚集， 使灯丝达到白炽状态而发光。 但是实际的灯丝并 非整条都能白炽发光。 一条实际的灯丝包括白炽发光段和非白炽发光段， 例如灯丝两端总是需要有引出段与电极连接， 该引出段就属于非白炽发光 段； 又如， 对于较长的灯丝， 为防止灯丝在高温工况下因重力作用而过份 下垂变形， 或者为了改变灯丝方向， 在灯丝的中部还需要设置若干支撑段， 支撑段通常也属于灯丝的非白炽发光段。 灯丝的非白炽发光段虽然不会产 生白炽发光， 但是仍然流过与白炽发光段一样大小的电流， 产生电阻热， 消耗能量。经实验， 灯丝的非白炽发光段消耗的电能占灯丝总耗能的 3〜 5 %。 然而， 目前尚无人关注灯丝的非白炽发光段带来的能耗问题， 现有技术 还没有提供解决此问题的技术措施。 实用新型内容
本实用新型的目的是提供一种可提高能效的灯丝。
本实用新型是这样实现的： 一种灯丝， 包括白炽发光段和非白炽发光 段， 特别地， 在非白炽发光段设置有短路导体， 流过非白炽发光段的电流 被短路导体短路。 本实用新型利用短路导体使灯丝的非白炽发光段只有很 小的电流流过， 甚至没有电流流过， 从而大大降低了非白炽发光段的能耗。
本实用新型的优点是提高了灯丝的整体能效， 使灯泡产品更节能。 附图说明
图 1是本实用新型实施例 1的结构示意图；
图 2是本实用新型实施例 2的结构示意图；
图 3是本实用新型实施例 3的结构示意图。 具体实施方式
实施例 1
图 1所示的灯丝 1是一种单螺旋灯丝。 灯丝两端与灯泡电极 2连接的 引出段没有螺旋， 呈直线状。 直线状的引出段不会产生白炽发光， 属于灯 丝的非白炽发光段。在灯丝的引出段上包裹有套管状的短路导体 3。短路导 体 3将原本流过引出段的电流短路， 使灯丝的引出段不再消耗电能， 提高 了灯丝的能效。 短路导体 3可用钼制成。 短路导体 3与电极 2之间既可以 焊接也可以不焊接。
实施例 2
图 2所示的灯丝是一种双螺旋灯丝。 这种灯丝的白炽发光段有两道螺 旋， 但是灯丝的与灯泡电极 2连接的引出段只有一道螺旋。 本实施例在灯 丝的中部还设置有支撑段， 支撑段也是只有一道螺旋。 支撑段由灯泡泡壳 内的支架 4支撑。 双螺旋灯丝的引出段和支撑段都有一道螺旋， 在通电的 时候可能发出红光， 但是并不能达到白炽发光状态， 所以此段灯丝仍属于 非白炽发光段。 本实施例在灯丝的引出段和支撑段都包裹有套管状的短路 导体 5、 6。 短路导体 5、 6将原本流过引出段和支撑段的电流短路， 由此提 高了灯丝的能效。 与前一实施例相同， 短路导体 5、 6可用钼制成。 短路导 体 5与电极 2之间既可以焊接也可以不焊接。
实施例 3
图 3所示实施例的灯丝结构与图 2相同。 不同之处在于本实施例的短 路导体 7、 8是安插在灯丝引出段和支撑段的螺旋内的芯线。 芯线可用钼制 成。 芯线 7与灯泡电极 2之间既可以焊接也可以不焊接。
本实用新型并不要求在灯丝的所有非白炽发光段都设置短路导体。 例 如在图 2和图 3所示的实施例中， 如果灯丝的引出段很短， 耗能甚微， 那 么作为一种简化的实施方式， 也可以省去设置在引出段的短路导体， 仅在 灯丝的支撑段设置短路导体。
