|1. (WO2018205454) DIMMABLE AND COLOR-TUNABLE LED LIGHT ENGINE MODULE AND LIGHTING DEVICE|
|Applicants:||SHINEON (BEIJING) TECHNOLOGY CO., LTD
|Title:||DIMMABLE AND COLOR-TUNABLE LED LIGHT ENGINE MODULE AND LIGHTING DEVICE|
Disclosed in the present invention is a dimmable and color-tunable LED light engine module, compatible with a silicon controlled dimmer to realize a dimmable and light-tunable function through a simple operation. The LED light engine module comprises: an alternating-current power supply, a silicon controlled dimmer, a linear IC, and an LED light group composed of a plurality of LED light sources from an LED1 light source to an LEDn light source, n≥2. The color temperature of each of the LED light sources is different from one another. The linear IC and the LED light group form the LED light engine module. The linear IC drives one by one each of the LED light sources in the LED light group. The silicon controlled dimmer is connected with the LED light engine module by means of an external circuit. The alternating-current power supply drives the silicon controlled dimmer to regulate the color temperature of the LED light engine module. Further disclosed in the present invention is a lighting device using the described LED light engine module.
