Abstract
The invention relates to a luminaire () having a housing which is closed by a translucent cover (). The housing accommodates a light source and control gear (), the light source being formed from a plurality of LEDs () arranged on at least one circuit board (). According to the invention the light from the LEDs () is coupled into at least one light guide () which extends from the cover () towards the LEDs (). The coupled-in light from the LEDs () is guided in the light guide () to the cover () and is preferably emitted diffusely.
