Description

一种可调光调色的LED光引擎模组及照明装置 技术领域
本发明属于照明领域，具体涉及一种可调光调色的LED光引擎模组及照明装置。
背景技术
传统实现调光调色功能的方案，如图1所示：A/B路光源分别独立的被A/B路电源驱动。A/B路光源采用不同色温的LED；通过调节控制源A/B→A/B路电源输出的驱动电流被相应调节→A/B路光源输出的光通量相应变化。驱动电流越大，光通量越高，反之，驱动电流越小，光通量越小。A/B路光源的色温不同，两路光源输出的光通量变化时，整体输出的光通量及色温会相应变化，因此实现了调光调色的功能。
但是，不同光源通过不同电源驱动，操作比较不便。
发明内容
本发明的目的在于提供一种可调光调色的LED光引擎模组，兼容可控硅调光器，实现简易操作的调光调色功能。
为了达到上述目的，本发明的具体技术方案如下：
一种可调光调色的LED光引擎模组，包括：交流电源、可控硅调光器、线性IC、由LED1光源至LEDn光源的多个LED光源构成的LED灯组，所述n≥2；每个所述LED光源的色温均不同；
所述线性IC和所述LED灯组构成所述LED光引擎模组，所述线性IC逐个驱动所述LED灯组中的每个LED光源；

进一步地，所述可控硅调光器接在所述交流电源的输入端。
进一步地，色温调节具体包括：
当所述可控硅调光器调到最大功率时，所述LED灯组中从LED1光源至LEDn光源全亮；
当所述可控硅调光器的功率逐渐调低时，LEDn光源熄灭，LED1至LED(n-1)光源亮；
当所述可控硅调光器的功率调至最低时，只有LED1光源或者LED1和LED2光源亮。
本发明的另一个目的在于提供一种照明装置，所述照明装置采用上述的LED光引擎模组。
本发明提供的一种可调光调色的LED光引擎模组，由交流电直接驱动，同时，兼容可控硅调光器，用可控硅调光器就可以让模组实现调光调色的功能，而且符合安规、电磁兼容等要求。
附图说明

图2为本发明提供的以线性IC为核心的可调光调色的LED引擎模组的电路图；
图3为图2所示的模块示意图；
图4为本发明提供的可调光调色的LED引擎模组的电路模块示意图；
图5为本发明实施例1中的实物图；
图6为图5中LED光源随可控硅调光器功率增大而逐渐全亮的状态图。
本发明的较佳实施方式
一种可调光调色的LED光引擎模组，如图2所示，包括：交流电源、可控硅调光器、线性IC、由LED1光源至LEDn光源的多个LED光源构成的LED灯组，n≥2；每个LED光源的色温均不同；

如图4所示，可控硅调光器接在交流电源的输入端，通过外部电路可控硅调光器与LED光引擎模组连接，交流电源驱动可控硅调光器调控LED光引擎模组的色温。
当可控硅调光器调到最大功率时，LED灯组中从LED1光源至LEDn光源全亮；
当可控硅调光器的功率逐渐调低时，LEDn光源熄灭，LED1至LED(n-1)光源亮；
当可控硅调光器的功率调至最低时，只有LED1光源或者LED1和LED2光源亮。
可控硅调光器能够将交流电源中的反向电压调整为正向电压，也就是能够不间断地实时通过调整电路电流来调控每个LED光源的色温。
由于LED1、LED2、LED3…、LEDn光源等处使用了不同色温的LED光源，使用可控硅调光器调光时，LED光引擎模组的色温会相应变化，实现了调光调色的效果。
