摘要： A lighting apparatus includes a circuit board and light emitting diodes (LEDs) attached to the circuit board. The LEDs are arranged in an array of row and columns and are attached to the circuit board are arranged in a single plane. A support substrate supports the circuit board. Optical elements are configured to redirect light from the plurality of LEDs. Each optical element is substantially the same as all other optical elements. Each LED is associated with a single optical element and each optical element is associated with a single LED. The lighting apparatus is configured to direct light away from the circuit board so that the light is directed so as to illuminate a substantially rectangular area that is off-center relative to the light assembly. The substantially rectangular area has an edge that is at least 14 feet in length.

摘要： A light assembly includes a thermally conductive support structure configured for outdoor use. LEDs are attached to a circuit board and thermally coupled to a heat sink. A single transparent substrate overlies the LEDs and includes a number of optical elements. Each of the plurality of optical elements is configured to direct light from each LED in three primary directions. Each optical element includes a first portion, a second portion, and a third portion. The first, second and third portions of each optical element are configured to direct light from the associated LED in a first, second and third primary direction, respectively. The first primary direction is a lateral direction, the second primary direction is also a lateral direction and the third primary direction is approximately orthogonal to the first and second lateral directions.

摘要： A lighting device includes a heat sink having fins on a first side and a mounting surface of a second side opposite the first side, a substrate attached to the mounting surface, a number of LEDs attached to the substrate, and a single transparent substrate with a number of optical elements, each optical element overlying an associated one of the LEDs. The device configured to direct light from the LEDs towards an area in a manner that does not create hot spots or result in dead spots on the area regardless of whether all of the LEDs of the plurality of LEDs or some of the LEDs of the plurality of LEDs are functional.

摘要： A lighting assembly includes LEDs arranged at a surface of a substrate, and optical elements proximate the LEDs such that each optical element overlies a single LED and each LED underlies a single optical element. Each optical element includes a first part, a second part intersecting the first part such that a normal to surface of the second part intersects a normal to the surface of the first part, and a third part extending away from the associated LED beyond a region between the first and second part. The LEDs and optical elements are configured such that light from each LED is directed towards an area to be illuminated in a uniform pattern covering the area.
