    摘要: A method for controlling an angular distribution of a light-beam emitted by a light-output device (102, 200) comprising a first set of light-sources (105, 211) comprising at least one light-source configured to emit light within a first angular range (221, 231, 241) and second set of light-sources (107, 210) comprising at least one light-source configured to emit light within a second angular range (222, 232, 242), wherein the first angular range is different from the second angular range. The method comprises the steps of: receiving (401) a dimmer setting (VDS) from a dimmer (101); controlling (404), if the dimmer setting is within a first predetermined range, the first set of light-sources to emit light within the first angular range; and controlling (405), if the dimmer setting is within a second predetermined range, the second set of light-sources to emit light within the second angular range. Through the method according to the invention the angular distribution of light emitted from a single light-output device may be controlled using a single switch, thereby avoiding the need for having a plurality of switches and/or new wiring which would otherwise be required.

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.

The light-output system (1) comprises a plurality of individually controllable light-output devices (6a-c) arranged in an array (5) of light-output devices with a light-output device pitch (PLS), and an optical system (7) arranged between the array (5) of light-output devices and the projection plane (3). The optical system (1) is configured to project light emitted by the array (5) of light-output devices in the projection plane (5) as a projected array of illuminated spots (11a-c) having a projection pitch (Pspot) that is larger than the light-output device pitch (PLS). Using this light-output system, practically all of the luminous power output by the light-output devices is used for projecting the light patterns.

    摘要: The invention relates to a light source and an illumination system. The light source (10) comprises a light emitter (20) and a light conversion element (30). The light emitter emits visible light of a first color through the light conversion element in a direction away from the light source. The light conversion element comprises a photoluminescent material (40) for converting at least a part of the light of the first color into light of a second color different from the first color. The light source further comprises conversion material (42) for converting at least a part of ambient light impinging on the conversion material into light of a third color (Ba) different from the second color. When the light emitter emits light, the color of the light emitted is mainly a mixture of the light of the first color and light of the second color. When the light emitter does not emit light, the color of the light emitted by the light source is determined by the reflected ambient light, light of the second color and light of the third color. As such, the color of the light source can be tuned when the light emitter does not emit light and can, for example, be made substantially identical to the color of the light emitted when the light emitter emits light.
