Description

LED灯具及其启动器
【技术领域】
本发明涉及LED灯控制技术领域，特别是涉及一种LED灯具及其启动器。
【背景技术】
由于LED具有节能、环保、高效的优点，且其基本不需要维护，发光效率高，因此LED作为照明光源越来越受到人们的青睐。目前，市场上的LED灯都是有固定的勒克斯输出，针对不同的光照需求时需要采用不同勒克斯输出的LED灯，这样会降低生产的效率；还有一些可以调节亮度的LED灯，其控制电路复杂，设计成本高。
【发明内容】
基于此，有必要提供一种可以提高生产效率且成本低的启动器。
此外，还提供一种LED灯具。
一种启动器，应用于LED灯具中，包括导电触脚、电容和电阻，所述导电触脚的数量为两个，用于连接在LED灯和外接的控制开关之间；所述电容连接在两个导电触脚之间，用于改变流经LED灯的电流；所述电阻并联在所述电容两端，用于在电容放电的时候分压以保证电路的安全运行。
在其中一个实施例中，所述两个导电触脚均为金属片触脚。
在其中一个实施例中，所述启动器的形状为圆柱体，所述导电触脚设置在所述圆柱体的底面。
在其中一个实施例中，所述电阻的阻值为1兆欧。
在其中一个实施例中，所述电容的容量值为0.1微法至4.7微法。
一种LED灯具，包括LED灯，还包括上述的启动器，所述启动器的一个导电触脚用于与所述LED灯的一个连接端连接，所述启动器的另一个导电触脚用于与LED灯的另一个连接端连接，或者所述启动器的另一个导电触脚用于外接元器件。
在其中一个实施例中，所述LED灯为T5、T8、T10、T12或G24的LED灯。
在其中一个实施例中，还包括镇流器，所述整流器与所述LED灯连接。

图8为第六实施例中的LED灯具的原理图。
【具体实施方式】
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参照图1，为一实施例中启动器的内部结构图。
该启动器应用于LED灯具中，包括导电触脚112、导电触脚114、电容C和电阻R。
导电触脚112和导电触脚114的材质均为金属，即为金属片触脚。导电触脚112和导电触脚114用于连接在LED灯和外接的控制开关之间。在一个实施例中，所述金属为银。可以理解，在其他实施例中，导电触脚112和导电触脚114的材质可以为任何一种导电的金属。
电容C连接在导电触脚112和导电触脚114之间，用于改变流经LED灯的电流。
电阻R并联在所述电容C两端，用于在电容放电的时候分压以保证电路的安全运行。电阻R可以为定值电阻，也可以为可变电阻。
在一个实施例中，该启动器的形状为圆柱体，导电触脚112和导电触脚114设置在所述圆柱体的底面。该启动器的外观示意图如图2所示。
在一个实施例中，电阻R的阻值为1兆欧，电容C的容量值为0.1微法至4.7微法之间的任意数值。例如，电阻R的阻值为1兆欧，电容C的容量值为1微法，又如电阻R的阻值为1兆欧，电容C的容量值为0.68微法。可以理解，电阻R的阻值和电容C的容量值还可以采用其他值，这里不作严格限制。
请参照图3，提供了一种LED灯具。
该LED灯具包括LED灯210和上述的启动器220，其中LED灯210包括第一连接端a、第二连接端b、第三连接端c及第四连接端d。启动器220的一个导电触脚与LED灯210的第三连接端c连接，启动器220的另一个导电触脚与LED灯210的第四连接端d之间。输入电源230的正极通过控制开关K1与LED灯210的第二连接端b连接，输入电源230的负极与LED灯210的第一输入端a连接。
下面以图3为例说明该LED灯的工作原理：
当控制开关K1合上时，输入电源230给LED灯210供电，由于刚开始通电，电压几乎都加在了LED灯210上，LED灯210可以快速点亮。随着电容C1充电，电容C1的电压逐渐趋于稳定，而在电容C1放电时，并联在电容C1两端的电阻R1可以分压以保证电路的安全运行。电容C1的电容值大小直接影响输入LED灯210的供电电流大小，通过应用不同电容值的电容C1可以使LED灯210的勒克斯输出不同。因此，针对需要不同光照度的场所时，不需要提供勒克斯输出不同的LED灯具，而只需要应用具有相应电容值的电容C1的启动器220即可，启动器220设计非常简单，且相对于整个LED灯具来说，成本非常低。
在一个实施例中，LED灯210的第二连接端b和第三连接端c之间可以连接保险丝、电容或导线等。
在一个实施例中，控制开关K1还可以连接输入电源的负极与LED灯210的第一连接端a之间。
LED灯210可以为日光灯、圆筒灯或轨道灯等。另外，LED灯210中LED的型号可以为T5、T8、T10、T12或G24等，这里不作严格限制。
如图4所示，提供了另一实施例的LED灯具。
该LED灯具包括LED灯310和上述的启动器320，其中LED灯310包括第一连接端a、第二连接端b、第三连接端c及第四连接端d。启动器320的一个导电触脚与LED灯310的第三连接端c连接，启动器320的另一个导电触脚与LED灯310的第四连接端d之间，并且启动器320安装在LED灯310的灯管内。输入电源330的正极通过控制开关K1与LED灯310的第二连接端b连接，输入电源330的负极与LED灯310的第一输入端a连接。
如图5所示，提供了第三种实施例的LED灯具。
该LED灯具包括LED灯410和上述的启动器420，其中LED灯410包括第一连接端a和第二连接端b。启动器420的一个导电触脚与LED灯410的第二连接端b连接，启动器420的另一个导电触脚与输入电源430的正极连接。输入电源430的负极通过控制开关K1与LED灯410的第一输入端a连接。
图6～8分别第四、第五、第六种实施例的LED灯具，其结构分别是在图3～5的基础上添加一个镇流器（540、640、740）。其他元器件的连接方式这里不再赘述。另外，为了方便起见，图4～7中的启动器均用一个圆圈（320、420、520、620、720）表示，启动器的具体结构请结合图1。
上述LED灯具及其启动器，通过在电容的两端并联一个电阻，这样在电容放电时可以保证电路的安全运行，针对不同的光照需求时，采用相应电容值的电容来改变流经LED灯的电流，从而达到改变LED灯输出的勒克斯，而生产带有不同电容值的启动器比直接生产不同勒克斯输出的LED灯的效率高，且启动器的结构相对于传统的控制电路要简单，降低了设计成本。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
