Claim Text:
1. A dimmable illumination device, comprising: a first set of light sources being driven by a first circuit driver; a second set of light sources being driven by a second circuit driver; and a dimming control system including dimming control logic, the dimming control logic being configured to provide driving instructions to the first circuit driver and the second circuit driver, wherein the dimming control logic is programmed to monitor a dimming input signal for the illumination device and determine that the dimming input signal has reached a transition condition such that the first set of light sources is to be enhanced by the second set of light sources, wherein the transition condition is an extended transition condition comprising an upper bound and a lower bound, wherein the driving instructions cause both the first and second set of light sources to be fully activated at the same time and fully deactivated at the same time, and wherein the extended transition condition spans an entire operating range of both the first and second set of light sources.
