Description

LED照明灯管
【技术领域】本实用新型设置一种照明装置,尤其是指一种LED照明灯管。
【背景技术】传统的室内照明工具为白炽灯和荧光灯,由于白炽灯存在能耗高、耗电量大的缺点,不符合节能环保的要求,其已逐渐被淘汰,现在普遍采用荧光灯作为照明工具,相比于白炽灯而言,其具有能耗低的优点。而随着人们对绿色环保照明的要求越来越高,具有低能耗、高光效、使用寿命长等诸多优点的LED照明灯管开始应用于普通照明,其相关技术也取得了长足的发展。如国家知识产权局于2006年3月22日授权公告的专利号为ZL200520002000.1的实用新型专利即公开了一种LED照明灯管,其包括有透明管体、设置于透明管体两端的灯头、安装于灯头内侧的支座、两端分别固定于两侧支座上的安装有LED的PCB板及设置于灯头内侧的直流转换器,直流转换器的电源输入端与灯头的电极脚连接,电流经转换成直流电后接通PCB板,将该LED照明灯管安装于现有灯管支架上即可起照明之用。但现有的LED照明灯管均仅使用市电作为工作电源,由于市电的不稳定,存在着LED照明灯管因为市电的突然断电而无法继续提供照明的情况,这给人们造成了某种程度上的不便。故此,有需要提供一种具有备用电源的LED照明灯管,可以在市电断电的情况下继续为LED照明灯管供电,使其继续提供照明,而满足人们的使用需要。
【发明内容】本实用新型的目的在于克服现有LED照明灯管所存在的缺点,提供一种在市电断电的情况下可继续照明的LED照明灯管。
本实用新型的目的是这样实现的:一种LED照明灯管,包括有透明管体、设置于所述透明管体两端的左灯头和右灯头、设置于所述透明管体内的LED组、滤波整流电路及备用电源,所述滤波整流电路的输入端与所述左灯头的电极脚连接,输出端连接入所述LED组,所述备用电源并联接入于所述左灯头的电极脚与所述滤波整流电路之间,其包括有顺次连接的降压电路、充电电路、电池、逆变电路、切换电路及输入端连接于所述降压电路的输出端而输出端分别接入所述逆变电路和所述切换电路的市电控制电路,所述减压电路输入端连接于所述左灯头的电极脚,所述切换电路的输出端连接于所述滤波整流电路的输入端。
上述LED照明灯管中,所述滤波整流电路与LED组之间串联接入有调光电路。
上述LED照明灯管中,所述左灯头和右灯头为T8或T5规格。
相比于常见的LED照明灯管,本实用新型的有益效果在于:本LED照明灯管设置有备用电源,当市电供应时,市电可为LED组提供工作电源而使其发光以做照明之用,并同时对备用电源充电,而当市电断电时,备用电源可为LED组提供工作电源,使LED组继续发光而起照明之用,解决了常见LED照明灯管在市电突然断电的情况下无法继续照明的缺点;而在滤波整流电路与LED组之间串联接入调光电路,可调节LED照明灯管的光亮度。
【附图说明】下面结合附图及实施例对本实用新型做进一步说明。
图1是本实用新型LED照明灯管的结构示意图。
图2是本实用新型LED照明灯管的控制电路的原理方框图。
【具体实施方式】参考图1所示,本实用新型所公开的LED照明灯管包括有透明管体10、设置于透明管体10两端的左灯头20和右灯头30、设置于透明管体10内的LED组40、滤波整流电路50及备用电源60,其中,滤波整流电路50的输入端与左灯头20的电极脚210连接,其输出端连接入LED组40,备用电源60并联接入于左灯头20的电极脚210与滤波整流电路50之间。再结合图2所示,备用电源60包括有顺次连接的降压电路600、充电电路610、电池620、逆变电路630、切换电路640及输入端连接于降压电路600的输出端而输出端分别接入逆变电路630和切换电路640的市电控制电路650,减压电路600输入端连接于左灯头20的电极脚210,切换电路640的输出端连接于滤波整流电路50的输入端。
一般地,备用电源60的电路部分与滤波整流电路50设置于同一电路板上并将其置于左灯头20的容置腔200内,而将备用电源60的电池620置于右灯头30的容置腔300内,当然,其并不限定于上述设置方式,也可将滤波整流电路50和备用电源60设置于透明管体10、或左灯头20的容置腔200、或右灯头30的容置腔300的内部,或者将滤波整流电路50和备用电源60分设于上述三者的内部。
工作时,市电70经由左灯头20的电极脚210输入,经滤波整流电路50转换后接通LED组40,LED组40发光而起照明之用,市电70的另一路同时经降压电路600、充电电路610而为电池620充电。当市电70断电时,市电控制电路650控制逆变电路630、切换电路640而使电池620为LED组40提供工作电源,使LED组40继续发光而起照明之用。
更为理想地,可在滤波整流电路50与LED组40之间串联接入调光电路660,以起调节LED组40的光亮度的作用。
左灯头20与右灯头30的规格可采用T8或T5规格,以使LED照明灯管可安装于现有的荧光灯灯架上,而无需另外配置灯架,方便LED照明灯管的使用,且可降低成本。
