Abstract

本实用新型提供一种耐用日光灯,采用在现有日光灯的基础上增设两根(或一根)灯丝的办法来实现。该耐用日光灯在使用时有一对灯丝发亮,其中一根烧断后,与它并联的另一根即能通电发亮。具有工艺简单,再投入的成本低,使用寿命长的特点,有较好的经济效率和较强的市场竞争力。

Description

耐用日光灯
本实用新型涉及一种白炽灯，尤其是一种耐用日光灯。
目前普遍使用的日光灯只有一对灯丝，一旦一根灯丝烧断即报废，使用寿命短，造成浪费且利用率低。
本实用新型的目的是提供一种工艺简单，成本低，寿命长的耐用日光灯。
本实用新型的目的是通过增设两根(或一根)灯丝的办法来实现。
以下结合附图作进一步详细描述。
图1为本实用新型的结构示意图。
本实用新型在原有一对灯丝的基础上，保留日光灯灯管，灯丝接柱，灯头不变，增设两根(或一根)灯丝。如图：ACB和A′C′B′是原日光灯的两根灯丝，若装上长度略比原灯丝长的灯丝ADB和A′D′B′，当通电时，灯丝AC B及A′C′B′发亮，而灯丝ADB及A′D′B′不壳或只有一点红光。若灯丝ACB烧断，则ADB仍通电发亮。若只装上长度略比原灯丝长的一根灯丝ADB，可达到同样效果。因此，本实用新型的日光灯使用寿命比普通的日光灯的使用寿命长。
本实用新型工艺简单，再投入的成本低，使用寿命长，有较好的经济效益和较强的市场竞争力。
