摘要： The present invention relates to lighting device (10). The lighting device comprises a light guide plate (12), and at least one array of light emitting diodes (LEDs) (14), which LEDs are accommodated in holes arranged in the light guide plate, wherein each hole has: at least two side facets (18) through which light from the LEDs is to be laterally coupled into the light guide plate, and at least one corner (20) formed by two converging side facets of the at least two side facets. This promotes TIR at adjacent light sources and therefore diminishes losses due to absorption or scattering at adjacent holes.

摘要： A waveguide (40; 51; 61), arranged to guide light from at least one light source (53a-c), the waveguide comprising at least one guiding edge (43; 50a-c; 60) adapted to contain the light in the waveguide (40; 51; 61), and an extraction edge (44; 50d) adapted to enable extraction of the light from the waveguide (40; 51; 61), wherein the guiding edge (43; 50a-c; 60) is configured to reflect the light on its way towards the extraction edge (44; 50d). The guiding edge (43; 50a-c; 60) is further configured such that a direction (xr1, Xr2) of reflection of a ray of light impinging on the guiding edge (43; 50a-c; 60), in a given direction (xi) of incidence relative to a general direction (X0) of extension of the guiding edge (43; 50a-c; 60), is dependent on a position (P1, P2) of incidence along the guiding edge (43; 50a-c; 60). The waveguide may be configured such that virtually no light is lost through back-scattering or unintentional extraction or outcoupling through the at least one guiding edge.

摘要： An optical arrangement comprising a light guide (101) having a light-entry portion (103) with a light-entry surface (105), a tapering portion (107) with a light reflecting surface, and a light-exit surface (109). The light-entry portion (103) is arranged to guide light from the light-entry surface (105) in a first direction (x) towards the light reflecting surface (H I), the light reflecting surface being arranged in relation to the first direction (x) so that incident light from the light-entry portion (103) is reflected towards the light-exit surface (109). A light transmitting layer (113) is adapted to transmit light diffusively and arranged to cover at least a portion of the light-entry edge surface (105) of the light guide (101). The arrangement is e.g. suitable for use in a LED based luminaire and allows for efficiency and forming of a light beam able to fulfill glare requirements. The arrangement may advantageously be used in a downlighting application.

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.
