A lighting assembly is provided with a housing defining a cavity that is aligned along a longitudinal axis. A light source is supported by the housing and aligned with the longitudinal axis. A lens is supported by the housing to collimate light from the light source. An image plate with a plurality of apertures formed through passes a portion of the collimated light as light segments. An exit lens includes a first series of optics arranged on a first plane spaced apart from the image plate at a first focal distance to focus the light segments at a first distance from the housing, and a second series of optics arranged on a second plane spaced apart from the image plate at a second focal distance to focus the light segments at a second distance from the housing. The second focal distance is greater than the first focal distance.

Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.

The present invention relates to an optical device that enables a light beam from a light source to be redirected in a specific direction and without having to adjust the tilt angle of the light source with respect to a horizontal working plane, distributing the light homogeneously in said horizontal working plane, wherein the invention furthermore relates to a desk lamp comprising said optical device which avoids the problem of blinding generated by the direct line of sight of the light source, since the light source is arranged below the viewing plane of a user who uses said desk lamp, in addition to the fact that said desk lamp does not invade the user's work area.

In a light source device, an axis extends from a light-emitting face and perpendicularly to the light-emitting face. A reflective surface includes a curved surface defined by rotating a first arc which is a part of an ellipse around the axis. The ellipse has a first focal point and a second focal point which are located on the light-emitting face. The second focal point is located adjacently to the first arc with respect to a center of the ellipse. A distance from the first focal point to the axis is shorter than a distance from the second focal point to the axis.

The invention provides a luminaire comprising an optical element configured to spread light uniformly across a full visible face of the luminaire. The optical element comprises a central region and an outer peripheral region, each configured to receive light emitted by a light source arrangement and to direct this light out through a respective region of the light exit area of the luminaire. The central region receives light through a central transmissive surface portion which partially bounds it across its top. A further reflective tapered portion of the central region acts to reflect light incident at either of its two opposing sides, and provides a mixing function both within the central region of the optical element and within an inner compartment of the luminaire which extends between the optical element and the housing.

The light fixture with rotatable light source drives the light source assembly to rotate through the rotatable lamp holder, the light intensity changes during the light source assembly rotates around the center line of rotation. The light fixture will produce a sparkling effect especially suitable for jewelry lighting, so that jewelry is shining at all times.

A light outputting apparatus includes a light source that outputs a first light flux, a collimator that parallelizes the first light flux, a light separator that separates the first light flux into a first partial light flux and a second partial light flux, a first light flux width expander, and a second light flux width expander. The light separator causes the first partial light flux to exit in a first direction and the second partial light flux to exit in a second direction. When a first plane is assumed to be a plane containing the first direction and the second direction, the first light flux width expander expands a width of the first partial light flux in a direction along the first plane, and the second light flux width expander expands a width of the second partial light flux in a direction along the first plane.
