Abstract:
A light emitting device includes a first light emitting diode (LED) emitting a first light emission of at least a first wavelength, and a second light emitting diode emitting a second light emission of at least a second wavelength. The second LED is placed in close proximity to the first LED such that after a mixing length from the first and second LEDs, a combination of the first and second lights is perceived as one color in the human vision. In use, the first and second LEDs are alternately driven by a power source in the time domain.
