Abstract: Light engines for luminaires that include a printed circuit board of a geometric shape, light emitting diodes provided on the PCB, and an optic that is mounted on the PCB to cover the LEDs. One or a plurality of light engines may be mounted in a luminaire. The light engines may be arranged in any orientation within a luminaire and such arrangement may be specifically tailored to the geometric shape of the luminaire, if desired. The light engine design of embodiments contemplated herein allows customization of the pattern of emitted light from a luminaire, which is impacted by the type of optic (i.e., Type I-V) incorporated into each light engine in the luminaire and the rotational orientation of each optic in such light engines.

Abstract: A suspended light fixture includes a housing having first and second members configured to engage one another in a closed position and disengage from one another in an open position. For example, one member can include a cover, and the other member can include a housing body. The housing contains at least one internal component coupled to one of the members. The first member is configured to receive at least one cable. At least one cable gripper is coupled to the first member. Each cable gripper is slidable along a corresponding cable in a first direction and configured to only allow movement of the cable gripper in a second, opposite direction, upon operation of a mechanism. Movement of the cable grippers in the first direction causes corresponding movement of the first member, towards the open position. In the open position, the internal components are accessible for maintenance or another activity.
