Description

一种带安全保护电路的灯饰
技术领域
本实用新型涉及一种灯饰,具体说是灯饰安全保护电路的改进技术。
背景技术
目前,人们在灯饰行业中的安全保护电路大多采用一次性保险丝作为过流保护元件,比如低熔点的金属锡条,但这种一次性保险丝在熔断后需要及时更换,因此,使用起来非常麻烦且操作不安全。灯饰行业中装饰灯因使用效果的需要,经常串联或并联多路灯泡,灯泡在使用时呈现出多样的变化,这样,灯饰在安全保护电路方面提出了更高的要求。
本实用新型的目的是提供一种安全保护性好、使用方便的灯饰。
本实用新型通过以下技术方案来实现本发明目的。
一种带安全保护电路的灯饰,包括主干路,与主干路相连的支路以及安装在支路上的灯,其特征在于:所述灯饰的电路上安装有自复式保险装置。
所述自复式保险装置安装在灯饰电路的主干路上。
所述自复式保险装置安装在灯饰电路的支路上。
所述自复式保险装置为自复保险丝。
所述自复保险丝为PPTC聚合物自复保险丝。
所述自复式保险装置为双金属弹片。
所述灯饰为圣诞灯饰或节日喜庆灯饰。
本实用新型与现有技术相比具有以下优点。
灯饰的电路上安装自复保险丝,当电路发生过载或短路时,自复保险丝呈现出高阻抗,阻断电路,保护负载,故障排除后,自复保险丝自行恢复到可通电状态。所以,自复保险丝可以一次安装,反复使用,使用非常方便、安全。
附图说明
图1为本实用新型的自复保险丝安装在一路串联灯泡的主干路上的结构示意图;
图2为本实用新型的自复保险丝安装在多路串并联灯泡的主干路上的结构示意图;
图3为本实用新型的自复保险丝安装在由IC控制多路串并联灯泡的主干路上的结构示意图;
图4为本实用新型的自复保险丝安装在多路串并联灯泡的支路上的结构示意图。
具体实施方式
下面结合附图对本实用新型作进一步详细描述。
本实用新型中的自复式保险装置采用自复保险丝或双金属弹片或其它具有相同功能的部件,图1、图2与图3为本实用新型中的自复保险丝a安装在灯饰的主干路上的三种实施例,当然,自复保险丝a还可以安装在灯饰的各支路上。本实用新型中的自复保险丝a采用PPTC聚合物自复保险丝,PPTC聚合物自复保险丝由高分子材料和导电微粒组成,其工作原理如下:正常情况下,导电微粒在高分子材料中构成链状导电通道,元件维持在低阻抗状态。当电路在过载或短路时,大电流产生的热量使高分子材料迅速膨胀,切断链状导电通道,元件由低阻抗瞬变为高阻抗,阻断电路,保护负载。故障排除后,高分子材料冷却自动收缩,导电通道重新链接,元件又自行恢复至初始状态,从而实现“重复使用,无须更换,一劳永逸”的目的。
