Embodiments of the invention include a luminaire with an elongated luminaire body and at least one longitudinal luminaire flange each of which extend longitudinally from one end of the luminaire body. The luminaire body being shorter than the luminaire length measured from the ends of both longitudinal luminaire flanges. The luminaire body can include a channel with a plurality of light sources, optical elements, power lines, and/or control lines. A connector is also disclosed according to some embodiments of the invention that can be used to physically and/or electrically couple two luminaires together. The connector can couple the luminaires at a T-bar.

An indirect LED light fixture for illuminating tennis courts and other indoor facilities is disclosed. The light fixture is highly efficient and provides for even distribution of light. The fixture employs at least one LED (Light Emitting Diode) light source equipped with at least one optical lens having a predefined light output beam pattern. Light emitted by the LED is controlled and directed to a ceiling or a wall by a lens to achieve highly uniform illumination of the surface area desired to be illuminated. The beam angle of the light emitted by the LED light source may be adjustable by adjustment of the position of the lens in relation to the light emitting side of the LED light source. The light fixture has minimal reflection losses, a wide adjustment range of light output, and a high color rendering index.

A light shaping article includes a solid optic having a cross-sectional profile including an input interface; a convex output surface opposite the input interface; a concave first side surface extending between the input interface and the convex output surface; and a second side surface opposite the concave first side surface extending from between input interface to the convex output surface. The concave first side surface and the convex output surface are configured such that, when the solid optic receives input light having an input angular range in a plane of the cross-sectional profile, the solid optic guides the light to and emits the light from the output surface in an output angular range in the plane. A prevalent propagation direction of output light in the output angular range is tilted toward the second side surface relative to a prevalent propagation direction of input light in the input angular range.

A thermosyphon light engine and luminaire including the same are provided. The light engine includes a condenser, an evaporation chamber, and a connecting element therebetween. The condenser returns a gaseous substance located therein to a liquid substance. The evaporation chamber includes a solid state light source, a working liquid, and an optical element that beam shapes light emitted by the at least one solid state light source. The solid state light source is immersed in the working liquid, such that heat generated by the solid state light source changes the working liquid into a gaseous substance. The gaseous substance travels through the connecting element to the condenser, which returns the gaseous substance to a liquid substance. The liquid substance then travels through the connecting element back to the evaporation chamber.

A lighting device having a support element with an elongated receiving region which has a U-shaped cross-section and having a first limb of the U, a second limb of the U, and a connecting limb that connects the two limbs of the U. The lighting device further has an LED lighting module with at least one LED for generating light in order to emit a light of the lighting device, the LED lighting module being arranged on the support element in a retained manner. The lighting device further has a contacting element for supplying power to the LED lighting module. The connecting limb has a through-opening, the contacting element and LED lighting module being arranged so as to be connected in an electrically conductive and reversibly releasable manner such that the electric connection passes through the through-opening.
摘要:
The invention described herein is a very thin flat panel LED luminaire, including a flat baseboard, a flat reflection panel, a flat acrylic panel, a flat diffusion panel, LED bar, and aluminum encasement frame which combines with the baseboard to form the chassis for the luminaire. The LED bar is placed along either or both sides of the stack. The acrylic panel is printed with a mesh-like mask pattern of dots in a pattern in which the density of the pattern is decreases the farther away from the LED bar the pattern is, differentially coupling the light from the point source LED bar from the reflection panel into the flat acrylic panel so that illumination across the luminaire is substantially uniform.
摘要:
A post cap light includes first and second lenses around a light source. The light source may be powered by batteries, an external supply or by an integrated solar panel. The first lens and second lenses may provided different lighting effects to light emitted from the light source. The first lens may be a faceted lens while the second lens, external to the first lens, may include vertical flutes, grooves and ridges. An internal reflector may reflect downward projecting light sideways through the second lens.
