Abstract
Proposed is a luminaire (), comprising light sources () and optical elements (). The light sources () are arranged in a first () and a second array (), while the optical elements () are arranged in a first () and a second section (). The first 'light sources' array () and the first Optical element' section () form a first group (), and the second array () and the section () form a second group (). The luminaire () is characterized in that the optical elements () of each group are arranged to have different beam shaping characteristics, and the arrays () are arranged to be individually addressable. This is especially advantageous in illumination applications where the control of the beam shape is required or desired. Advantageously, the invention provides a luminaire () capable of adjusting the beam shape without using an adjustable optical system. Moreover, the control bandwidth of the light sources limits the speed with which the beam shape can be adjusted.
