Abstract
The invention relates to an illumination device comprising a plurality of LEDs () arranged on a carrier, an optical element disposed in a path of light emitted by at least one of said LEDs (), and a driving unit for operating at least one of said LEDs (). The driving unit in a first operation mode drives at a selected power a first selection of LEDs (, FIG.A) to issue a first beam with a device light flux and with a first beam width, and drives in an at least one further operation mode at said selected power a further selection of LEDs (, FIG.B), different in at least one LED from said first selection, to issue a further beam with said device light flux and with a further beam width wider than the first beam width. The LEDs of the further selection of the LEDs are evenly distributed over the carrier.
