Abstract: An illumination device including an LED mounting platform (2) having a peripheral region (2a) and a relatively inner region (2b); at least one warm white LED (3) and at least one cool white LED (4) mounted adjacent the peripheral region (2a) of the LED mounting platform (2), and, at least one RGB LED (5) mounted adjacent the relatively inner region (2b) of the LED mounting platform (2); a diffusion cover (10) configured to allow light emitted from the at least one warm white LED (3), the at least one cool white LED (4), and the at least one RGB LED (5) to pass therethrough; and wherein at least one light emission characteristic of light emitted from the at least one warm white LED (3), the at least one cool white LED (4), and/or the at least one RGB LED (5) is configured to be selectably varied in response to an input control signal so as to produce a plurality of lighting modes.
