Abstract
A control circuit for color changing LED devices with volatile active emissions and hidden input jacks is disclosed. The circuit allows the device to use variously sized power adapters, and a plurality of colored LEDs positioned so as to emit a colored light show. The circuit also includes a volatile active dispenser to control volatile active emission rates. A hidden input jack is also disposed to provide additional power as required. Thus, the circuit provides the combination of illumination and/or ambient light, colored light shows, volatile active emission control, and combinations thereof, within a single standalone device.
