A dynamic color mixing LED device that includes a plurality of light
emitting diode units. Each light emitting diode unit includes e.g. a
first LED of a first color (e.g. red) and a second LED of a second color
(e.g. green). A third LED of a third color (e.g. blue can also be
provided). A controller supplies respective driving signals to each of
the first LED, second LED, and third LEDs individually. The respective
driving signals individually control relative intensity outputs of the
respective first LED, second LED, and third LED. With such an individual
control each of the light emitting diode units can be controlled to
output different color signals.
