  • Illumination device with electrical variable scattering element
    Patent number: 8427605
    Abstract: The invention provides an illumination device (1), arranged to provide illumination device light (250). The illumination device (1) comprising a light chamber (100), an electrically variable scattering element (500), and a controller (600). The light chamber (100) contains a light emitting diode (10) (LED) arranged to emit LED light (20); comprises a luminescent material layer (200) arranged remote from the LED (10) and arranged to absorb at least part of the LED light (20) and emit luminescent material emission (220); and comprises an exit face (301), through which one or more of the LED light (20) and the luminescent material emission (220) may escape to the exterior (22) of the light chamber (100) thereby providing illumination device light (250). The electrically variable scattering element (500) is arranged downstream of the luminescent material layer (200) and upstream of the exit face (301).
