Abstract: A reinforced visor for use with a luminaire includes a reinforcement system having a first rib bracket with a n-shape, a second rib bracket with a j-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 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.

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.

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: 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: 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: Methods and apparatuses are provided that can be utilized for accurate pre-aiming and installation of devices. The devices are pre-set to an aiming orientation relative to a universal reference plane. The reference plane is then correlated to a feature of a pole, tower, or other structure that will be used to elevate or suspend the devices. A position sensing subsystem is utilized to inform a worker when each device is correctly angularly oriented to the reference plane. The worker simply moves the mounting structure for the device to the correct three-dimensional angular orientation, uses the position sensor to confirm the correct orientation to within a highly accurate margin of error, and either locks the device in that orientation or marks the orientation. The pole, tower, or other elevating structure is preliminarily erected at its pre-designed location and pre-designed rotational orientation with the pre-aimed devices.

Abstract: A design of lighting fixture is presented whereby the outer glass lens—flat in prior art lighting fixtures—is bowed outward. The design of lighting fixture permits a plurality of LED modules to be contained therein, each with their own visor, without constraining the aiming angle of each due to interference between the outer lens and each individual visor. In this manner, an external visor may be omitted thereby obviating undesirable lighting effects such as uneven lighting while still maintaining a reduced effective projected area (EPA) as compared to prior art lighting fixtures with no external visor and a flat outer glass lens.
