Abstract
The present disclosure is directed to an LED engine comprising an LED light emitting board, a first circuit board, and a second circuit board. The LED light emitting board and two circuit boards are electrically connected via array cables. Either the first circuit board or the second circuit board has a linear LED driver IC. The first circuit board and the second circuit board, in combination, are configured to receive an AC line voltage, and drive the LED light emitting board. In some implementations, LEDs connected to the LED light emitting board are divided into two or more sections, each of which has a different correlated color temperature (CCT) to achieve CCT tuning. In some implementations, the LED engine further comprises a light engine housing.
