Abstract:
A device for modifying light distribution comprises a reflector surface (310) whose shape is at least partly based on a shape transformation directed to a geometric auxiliary surface (330). The shape transformation comprises i) division of the geometric auxiliary surface into longitudinal geometric surface segments (314', 315'), ii) displacements of at least some of the surface segments sideward so as to achieve a desired shape, and iii) addition of geometric connection-surfaces (316) between surface segments that are at least partly separated from each other by the displacements so as to form a stepped geometric surface corresponding to at least a part of the reflector surface. The geometric auxiliary surface can be select- ed according to a desired intensity distribution within an illumination pattern formable on a planar surface, whereas the shape obtained with the shape transformation can be selected according to the desired shape of the illumination pattern.

Abstract:
The disclosure generally relates to highly efficient light duct light splitters that are capable of splitting the light propagating within a light duct into two different ducts, with nearly 100 percent efficiency. In particular, the described light splitters are configured in a "Tee" shape with a reflective splitter element.
Abstract:
The invention relates to a lamp (1) with a longitudinally extended light source (2), comprising a likewise longitudinally extended light-bundling light conducting element (4), which extends parallel thereto and which is made of transparent material, and preferably with likewise longitudinally extended reflector and/or light-limiting means (3, 26), which guarantee that light radiated by the light source (2) is irradiated into the light-conducting element (4). In order to improve the glare suppression of the lamp (1), light diverting means for suppression the glare of the light are placed at the entrance of light into and/or the exit of light from the light-conducting element (4).
Abstract:
The invention relates to a box-type reflector (1) intended for external lamps (37), in which is a tubular lamp with its socket (36), especially a high pressure discharge lamp such as a high pressure sodium vapour lamp, burns in a horizontal position, the reflector unit (1) being delimited lengthwise (30), in reference to the longitudinal axis of the lamp, by front walls (21, 21', 22, 22'), and crosswise (11) by the sidewalls (4, 4', 5, 5', 6, 6'), the transversal axis (11) defining the inside width of the sidewalls. Inside the external lamp, the reflector unit (1) is mounted longitudinally (30) moveable relative to the socket (36), and/or at least part of each reflecting sidewall (4, 4', 5, 5', 6, 6') is formed by part of the reflector or by concave metal-coated side strips which are secured tilting in an adjustable manner on the upper and/or lower longitudinal edge, so that the inclination of the side strips (14, 15) can be adjusted relative to the transversal axis (11).
Abstract:
The present invention relates to a lighting device with adjustable lighting angle, comprising a carrier body, a light source arranged some distance from the carrier body, at least two substantially elongate reflector bodies which are arranged between the light source and the carrier body and provided with a reflective surface on the side facing toward the lamp, wherein the reflector bodies are mounted with the side facing toward the carrier body for pivoting on the carrier body and extend at least some distance under the carrier body from a pivot axis, and comprise an inner edge, and wherein adjusting means are provided which extend downward from the carrier body in the direction of the parts of the reflector bodies extending under the carrier body and engage thereon such that the pivot angle of the reflector bodies relative to the carrier body is adjustable therewith.
Abstract:
The present invention relates to a lighting device (1) that comprises a first light source (2) comprising one or more LED devices (21). At least a deformable reflective element (3) is optically coupled to said first light source, so as to receive light from said first light source, said reflective structure comprising at least a first portion (31) having a reflective surface (310) that reflects at least partially the light (L1) received from said first light source, and a second portion (32) that is solidly coupled to said first portion. Driving means (4) are operatively coupled to said second portion (32), which induce a deformation of said second portion that in turn causes a deformation of the reflective surface (310) of said first portion. The position of the focus point (F) of the light (L2) reflected by said reflective surface can thus be varied in a controlled manner.
