Abstract:
1. A lighting device with color temperature adjusting functionality, comprising: a light-emitting device array module, comprising: a first driving unit, being coupled to the first high CT light-emitting device array and used for driving the plurality of first high CT light-emitting devices to emit light; a second driving unit, being coupled to the first low CT light-emitting device array and used for driving the plurality of first low CT light-emitting devices to emit light; a third driving unit, being coupled to the second low CT light-emitting device array and used for driving the plurality of second low CT light-emitting devices to emit light; a fourth driving unit, being coupled to the second high CT light-emitting device array and used for driving the plurality of second high CT light-emitting devices to emit light; a main controlling unit, being coupled to the light-emitting device array module, the first driving unit, the second driving unit, the third driving unit, and the fourth driving unit, wherein the main controlling unit is used for controlling the first driving unit, the second driving unit, the third driving unit, and the fourth driving unit to selectively drive the first high CT light-emitting devices, the first low CT light-emitting devices, the second low CT light-emitting devices, and the second high CT light-emitting devices emitting light, so as to make the light-emitting device array module output a color light with a specific color temperature; and a power management unit, being coupled to the light-emitting device array module, the first driving unit, the second driving unit, the third driving unit, the fourth driving unit, and the main controlling unit and used for providing power to the light-emitting device array module, the first driving unit, the second driving unit, the third driving unit, the fourth driving unit, and the main controlling unit.
