Abstract:
Lighting applications which are particularly difficult to light because of “non-standard” target areas (or otherwise) would benefit from advancements in lighting design. That being said, conventional wisdom in lighting design has practical limitations—conventional means of visors at/on lighting fixtures (i.e., local visoring) can only become so long to provide beam cutoff before becoming prohibitively heavy or costly, for example. Local visoring can only be pivoted so far before beam shift occurs (e.g., shifting the physical location of maximum candela or photometric center), as another example. Conventional wisdom can only buy so much cutoff and beam control before the overall lighting design is impacted—and so an alternative approach is warranted. One such alternative approach which relies upon a combination of remote visoring and local visoring is discussed; additional approaches are also discussed.
Abstract:
An apparatus for retrofitting a HID lighting system includes using existing components of previously installed HID lighting systems such as its ballasts while replacing some capacitors to adjust the power supplied to a retrofit LED luminaire. Unused ballast drivers are removed, and a self-contained ballast driver assembly is mounted into the electronic control enclosure of the previously installed lighting system. Some of the retrofit LED luminaires include an uplighting lens, an optic, or a diffuser for providing uplight. An aiming bracket and an aiming plate allow for the horizontal aiming angle of a light luminaire to be set.

Abstract:
A method of sensing magnitude of lumen depreciation not only of a lamp of a lighting fixture, but other factors, by sensing a relative light level external of the lighting fixture to derive not only lamp lumen depreciation but total lumen depreciation from the fixture. An apparatus of monitoring light level of one or more lighting fixtures comprises a sensor positioned external of the lighting fixture(s), a comparator adapted to compare a measured actual lumen output signal from the sensor to a pre-set reference or threshold lumen output value. An error signal is generated by the comparator if the comparison indicates actual lumen output to have dropped below the reference or threshold lumen output. An alarm or communication can be actuated by the error signal to instruct corrective action to ensure relatively constant light levels to be maintained for the lighting system over time, thus providing ongoing assurance to the end user of proper system operation.
Abstract:
A reinforced visor for use with a luminaire includes a reinforcement system having a first rib bracket with a first m-shape, a second rib bracket with a second m-shape that is spaced away from the first rib bracket a first predetermined distance, and a first reinforcement member that is attached to the first rib bracket.

A reinforced visor for use with a luminaire includes a reinforcement system having a first rib bracket with a first n-shape, a second rib bracket with a second n-shape that is spaced away from the first rib bracket a first predetermined distance, and a first reinforcement member that is attached to the first rib bracket.
Abstract:
A reinforced visor for use with a luminaire includes an exterior shell, a first interior end rib bracket, and a first exterior reinforcement member. The exterior shell extends an overhang distance measured from the first interior rib bracket to a free end of the exterior shell, and the first exterior reinforcement member is attached to the first interior rib member with the exterior shell interposed between the first exterior reinforcement member and the first interior end rib bracket.
