The invention relates to an illumination device comprising a group of first light sources, a plurality of optical lenses, a plurality of beam generating elements, where each of the beam generating elements is configured to collect the light of at least one first light source to generate a light beam of the collected light and to pass the generated light beam to one of the optical lenses, a group of second light sources, and a plurality of shielding elements, where each shielding element is arranged between at least one of the second light sources and one of the plurality of optical lenses in such a way that said at least one of the second light source illuminates only one of the plurality of optical lenses.

A light source unit includes a green light source, a red light source, a blue light source, and a condenser lens system that condenses green light and red light at positions different from each other.

A lighting device comprising light radiation sources (12a, 12b, 12c, 12d) arranged in a plurality of cells (CI, C2, C3, C4) wherein each cell comprises at least one light radiation source, an output screen (16) for receiving light radiation from said light radiation sources (12a, 12b, 12c, 12d), and optical elements (18, 20) arranged between said cells (CI, C2, C3, C4) and said screen (16) so as to convey onto said screen (16) with a uniformly distributed intensity the light radiation produced by said light radiation sources (12a, 12b, 12c, 12d), the illumination of said screen (16) resulting from the superimposition of light radiation individually produced by the cells of said plurality (CI, C2, C3, C4).

The invention relates to an illumination device (10) comprising a plurality of concave shaped reflectors (20-1, 20-2), each reflector forming a reflector cavity (25) in which a light source (21) is provided for emitting light towards a light emission window (24). The illumination device of the above known kind is capable of emitting different light emission distribution thus improving its implementation in indoor applications.

The invention relates to lightweight LED lighting systems for permanent and semi-permanent mounting on elevated structures, the lighting systems having integrated support and thermal transfer features. The systems are particularly suited for elevated mast systems and specifically for mast systems that are repeatedly lifted and lowered such as drilling and service rig masts. Specifically, the invention improves a) the weight/lumen ratios of LED lamp assemblies and LED lighting systems, b) the net added weight of LED lighting systems, c) the footprint of LED light systems and/or d) obviates the need for removing LED lighting systems or their sub-assemblies when transporting mast systems.

A lighting module disclosed in an embodiment comprises: a plurality of light emitting devices on a substrate; and a reflector arranged in the direction of emission of light from each light emitting device on the substrate. The light emitting device has a light exit surface, and the reflector has a reflecting surface concave toward the substrate, at least a portion of the reflecting surface corresponding to the light exit surface of the light emitting device. The reflecting surface is arranged at a height that increases gradually in proportion to the interval from the light emitting device arranged in the light incident direction. The reflecting surface comprises a plurality of convex portions arranged in a first direction and first bridge portions that connect between the plurality of convex portions. The first bridge portions are arranged along the convex portions and are arranged to be lower than a straight line that connect high points of adjacent convex portions. The convex portions and the first bridge portions have the same length in a second direction, which is perpendicular to the first direction, and the area of the convex portions may be larger than the area of the first bridge portions.

A theatrical lighting apparatus including a plurality of light sources including a first light source and a second light source; and a plurality of reflector segments including first and second reflector segments; wherein the plurality of light sources are centrally located between the plurality of reflector segments; wherein each of the plurality of reflector segments has a focal point; wherein the first light source is located approximately the focal point of the first reflector segment; and wherein the second light source is located approximately the focal point of the second reflector segment. The plurality of light sources may include at least one white light emitting diode light source. The plurality of light sources may be fixed to a single heat exchanger centrally located between the plurality of reflector segments. The heat exchanger may be configured to be moved relative to the plurality of reflector segments by an actuator.

A table lamp has a lighting head with an asymmetrical light output. The lighting head is reversibly mountable to a support structure, so that the light output can be adapted to be optimised for positioning on either side (left or right) of a table.

A method and apparatus for collecting and projecting light into a specified target illuminance. A lens may be mounted or otherwise paired to a carrier to form a lens/carrier combination, which may then be mounted to a printed circuit board containing a light emitting diode (LED). The lens/carrier combination may establish an optimum optical relationship between the LED and the lens, such that a predetermined photometric distribution of the LED is collected by the lens, while the remaining photometric distribution of the LED is rejected by the carrier. The photometric distribution of neighboring LEDs, if any, may also be rejected by the carrier so that interference light may not be allowed into any lens. A diffuser may then spread the specified target illuminance into a beam pattern that may be compliant with specific standards (e.g., Department of Transportation or Economic Commission for Europe standards).

A lens assembly for implementing a low beam may include: a first lens including an incident surface having a shape enclosing a light emitting diode (LED), and an exit surface through which light of the LED exits in a direction perpendicular to the exit surface; and a second lens disposed on the exit surface of the first lens and configured to project the light of the LED that exits from the exit surface. The light of the LED that is projected through the second lens may form a low-beam pattern.
