Controllable high luminance illumination with moving light-sources |
摘要 |
The present invention relates to an illumination device (1) for providing a controllable illumination configuration. The illumination device comprises a light-source unit (2; 20) comprising a plurality of individually controllable solid state light-sources (8); and an optical element (3) arranged to modulate light from the solid state light-sources through a modulation area (16) of the optical element (3). The illumination device (1) further comprises an actuator (4) connected to the light-source unit (2) and controllable to move the light-source unit relative to the optical element (3) in such a way that the solid state light-sources (8) pass the modulation area (16) of the optical element (3) in succession; and a control unit (5) configured to control each of the solid state light-sources (8) to emit light with a time-varying intensity corresponding to the illumination configuration while the solid state light-source (8) moves past the modulation area of the optical element. |

1. An illumination device for providing controllable illumination, said illumination device comprising:
a light-source unit comprising a plurality of individually controllable solid state light-sources; an optical element arranged to modulate light from said solid state light-sources through a modulation area of said optical element; an actuator connected to the light-source unit and controllable to move said light-source unit relative to said optical element in such a way that said solid state light-sources pass through said modulation area of the optical element in succession; and a control unit configured to drive each of said solid state light-sources with a sequence of drive parameter values corresponding to an illumination configuration from when said solid state light-source enters said modulation area of the optical element until said solid state light-source leaves said modulation area of the optical element so said solid state light-source emits light with a time-varying intensity, said sequence of drive parameter values including at least three different drive parameter values. |
