Abstract
An outdoor light system comprising a plurality light elements linked to a central controller. Each light element include a translucent shell, plurality of LEDs positioned so as to emit a light show through the shell. 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 may be provided in each device as a source of illumination along with the LEDs The devices can be used as white light sources, for displaying a coordinated colored light shows, for displaying colored light schemes and for volatile active emission. The devices of disclosed the system 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 shows to be dependent upon ambient light intensity, motion detection and/or ambient noise. The devices and systems are suitable for outdoor home lighting, porch and deck lighting and path/driveway lighting.
