Abstract
A light element includes a decorative, patterned translucent outer shell and a base. The base supports a plurality of LEDs positioned so as to emit a light show through the shell. The device also includes a compartment for receiving and securing a replaceable volatile active cartridge and a heater for enabling the device to effectively emit an active ingredient from the cartridge when the cartridge is secured in the compartment A white light source is provided in the shell as a source of illumination along with the LEDs The device can be used as a white light source, for displaying a colored light show, for displaying colored light is schemes and for volatile active emission. The device may include an acoustic transducer for producing light and sound shows. The device may also include a light sensor, a motion detector and/or a microphone or acoustic receiver thereby enabling the light and sound show to be dependent upon ambient light intensity, motion detection and/or ambient noise.
