    摘要: Proposed is a luminaire (1), comprising light sources (10) and optical elements (20). The light sources (10) are arranged in a first (11) and a second array (12), while the optical elements (20) are arranged in a first (21) and a second section (22). The first ‘light sources' array (11) and the first Optical element’ section (21) form a first group (31), and the second array (12) and the section (22) form a second group (32). The luminaire (1) is characterized in that the optical elements (20) of each group are arranged to have different beam shaping characteristics, and the arrays (11,12) 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 (1) 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.

    摘要: A light emitting device is provided, comprising a light guide plate (100) and at least one light emitting diode (110). An array of mutually spaced apart reflective surface elements (103, 103′) is arranged between said back surface (102) and said front surface (103). The reflective surface elements (103, 103′) are non-parallel relative to said back surface (101) and front surface (102), and have a front side (104) facing said front surface (102) and a back side (105) facing said back surface (101). The back surface (105) of a reflective surface element (103) faces the front surface (104) of an adjacent reflective surface element (103′). The at least one light emitting diode (110) is arranged to emit light into a region (111) between two adjacent ones of said reflective surface elements (103, 103′). Since the reflective surface elements are located within the light guide, both the back surface and the front surface of the light guide plate may be made flat. This flat surface may easily be kept clean from dust and dirt.
