Description

恒流LED软灯带
技术领域
本实用新型属于电子技术领域,涉及一种恒流LED软灯带。
背景技术
LED作为一种新的光源,应用的领域越来越广。对于现有的LED软灯带,在电源不稳情况下,不但容易造成LED灯的发光度不均匀,而且容易使得LED灯损坏,因此,有必要对现有的LED软灯带进行改造。
实用新型内容
本实用新型要解决技术问题是提供一种恒流LED软灯带,该恒流LED软灯带在电源不稳定时也能正常工作、稳定性强。
本实用新型为解决上述技术问题所采用的技术方案是:
一种恒流LED软灯带,LED软灯带由多条LED支路以并联方式与直流电源相接,其特征在于,每一条所述的LED支路中串接有恒流芯片。
所述的恒流芯片采用ICTM1801型芯片,每一条LED支路中串接有3个LED灯。
本实用新型的有益效果:
本实用新型采用恒流芯片使得LED灯带的电流保持恒定,使得电源电压不稳定时,LED灯也能正常工作,发光均匀,且持续的恒流供电能有效保障LED软灯带的使用寿命。
附图说明
图1为实施例1的电路结构示意图。
具体实施方式
