Abstract:
Lighting device (1) comprising a plurality of LEDs (2a-2h) and a movable member (3) comprising a plurality of translucent segments (S1-S8) arranged such that the light from the LEDs (2a-2h) is transmitted therethrough. At least one of the translucent segments (S1-S8) comprises a wavelength conversion material. The lighting device (1) further comprises a control unit (5) for adjusting the color of the light emitted from the lighting device by controlling the power supplied to each one of the LEDs (2a-2h) in correspondence to the movable member (3), and by controlling the total power supplied to the lighting device (1) independently from the power supplied to each one of the plurality of LEDs (2a-2h).
