Abstract:
A white LED module includes a circuit board, at least one first LED light source on the circuit board and emitting a first white light having a first color temperature, at least one second LED light source on the circuit board and emitting a second white light having a second color temperature, higher than the first color temperature, a wiring structure in the circuit board to selectively drive the at least one first LED light source and the at least one second LED light source, and a transparent encapsulant on the circuit board, to cover the at least one first LED light source and the at least one second LED light source. The transparent encapsulant includes a transparent resin and a light-scattering powder in the transparent resin.
