Abstract: A system for emitting light (such as a luminaire) includes a first light emitting diode (LED) string and a first LED driver that is electrically connected in parallel to the first LED string. The system also may include a second (or more) LED string(s), each associated with an additional LED driver. One-way conductors and normally-open switches are used so that if one LED driver fails, the remaining LED driver(s) will deliver power to the failed driver's LED string so that the light remains operational, but with a reduced brightness.

Abstract: This document describes a mounting structure that is used to pivotally mount and orient a lighting device with respect to a support structure. The light fixture includes an interface plate having at least one tilt aperture. Each tilt aperture corresponds to a tilt angle of the light fixture. The mounting structure includes a mounting slot for engaging with a mounting element of the interface plate, along with a semi-circular slot that overlaps the at least one tilt aperture when the light fixture is pivotally mounted on the mounting structure. The mounting structure also includes a fastening device that, when routed through the semi-circular slot for insertion into the tilt aperture, orients the light fixture pivotally mounted on the mounting structure at a tilt angle. The fastening device is lockably engaged within the semi-circular slot at a position corresponding to the tilt angle.

Each of the pressure multiplying pads may be positioned opposite a corresponding LED. A flexible lens cover may cover the upper surface and the LEDs, while leaving the lower surface and pressure multiplying pads exposed so that the pads can contact a heat sink of the light fixture.
