    Abstract: The fixture includes an elongated back reflector along the longitudinal direction of the fixture and at least one light source mounted to a heat sink structure and arranged to emit at least a portion of light toward the back reflector. The back reflector redirects at least a portion of the light toward an exit lens which interacts with the light as it is emitted from the fixture. Both the shape of the individual fixture elements (e.g., the back reflector and the exit lens) and the arrangement of these elements provide an asymmetrical light output distribution. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall, or the fixture may be suspended from a in a pendant configuration.

    Abstract: An elongated lens profile having reverse total internal reflection (TIR) features that improve light extraction when the lens is used in conjunction with a plurality of light emitters. Solid state light emitters, such as LEDs, are arranged proximate to the elongated lens along a longitudinal axis of the lens body. The emitters, which may be grouped in clusters, emit toward a receiving surface of the lens. The receiving surface includes a plurality of reverse TIR features, also disposed along the longitudinal axis. These features may be defined by a series of recessed areas spaced along the longitudinal axis to correspond with the light emitters which can protrude into the negative space created by the recessed features. The recessed features may have more than one shape. The reverse TIR features improve light output uniformity, reducing hot spots along the lens, and improve output efficiency.

    Abstract: A linear solid state lighting fixture with asymmetric distribution. The fixture comprises an elongated back reflector along the longitudinal direction of the fixture. At least one light source is arranged to emit toward the back reflector. The source(s) are mounted to a heat sink structure such that at least a portion of light emitted from the source(s) first impinges on the back reflector which redirects at least a portion of the light toward an exit lens. The exit lens interacts with the light as it is emitted from the fixture. Both the shape of the individual fixture elements (e.g., the back reflector and the exit lens) and the arrangement of these elements provide an asymmetrical light output distribution. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall, or the fixture may be suspended from a in a pendant configuration.

    Abstract: Light fixtures having light bar elements therein. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. One or more LEDs can be mounted, sometimes in clusters, along the length of a base of the light bar which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These elongated lenses may be extruded from a diffusive material, for example, and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.

    Abstract translation: 在其中具有轻棒元件的灯具。 为了模拟现有的troffer式和表面贴装固定装置中的荧光灯泡的尺寸和外观，LED可以被布置在具有集成透镜的光条上，以使光扩散并形成输出光束。 一个或多个LED可以沿着光棒的基部的长度安装，有时以簇形式安装，然后可以将其插入固定装置中。 一个细长的透镜安装在LED上的基座上，使得从LED发出的光在透镜固定之前与透镜相互作用。 这些细长的透镜可以例如从扩散材料挤出，并且可以以各种方式成形。 例如，透镜可以被成形为将更多的光分散到侧面，即沿远离垂直于基部的法线的方向。
