The trigger device is configured to activate one or more of the lights upon the trigger device receiving the stimulus.
Abstract:
A lighting fixture that has a high ingress protection (IP) factor of IP68, the fixture comprising: a unibody fixture which has a lens shaped transparent resin (1) that directs the light coming from an LED light source (5) and a heat sink (4) protecting the LED light source and the resin from thermal damage.
Abstract:
Submitted is a modular stationary portable photovoltaic solar powered electrical generation, storage and supply device and light tower. The device consists of an elongated cube or rectangular prism shaped support structure with a flat base, flat sides and a flat decked top to form a protective crate shaped module when the various components, such as the solar panel arrays, telescoping mast, and light assembly or outriggers of the device are retracted to where the boundaries may be defined by the perimeters of the cube or prism. This modular design can allow for the modules to be stored, loaded, or shipped quickly, efficiently, and in greater quantities on flatbeds, in shipping containers, in warehouses, and other settings and modes where they can not only be packed end to end and side to side with no unused space, but can also be stacked up to three modules high for significantly higher storage density. The interconnectivity of multiple modules to create incrementally larger power generation, storage and distribution systems provides an easily adaptable solution to larger temporary power demands.
Abstract:
In some embodiments, a lighting system comprises: a light source; a lens spaced apart from the light source and including a first surface to receive light from the light source, the lens further including a second surface through which at least a portion of the light received by the lens exits; and a cover spaced from the lens and including a first surface to receive at least a portion of the light that exits the lens, the cover further including a second surface through which at least a portion of the light received by the cover exits; the second surface of the lens including a portion convex with respect to the light source; the first surface of the cover including a portion convex with respect to the light source and disposed over the convex portion of the lens. In some embodiments, the second surface of the cover is flat.
Abstract:
An attachable lighting system for a tower structure such as a drilling rig. A lighting system is described for a tower structure having at least one side. A lighting frame is attached to at least one side of the tower structure, the lighting frame including at least one light support bracket attached to the lighting frame for holding at least one lighting fixture. The system is attachable at any level of the tower, high or low.
Abstract:
The present disclosure describes light delivery and distribution components of a light duct that can be used as a luminaire, such as a bollard-style luminaire that can be useful for the illumination of pedestrian crosswalks, the light engine useful in the luminaire, and methods for making the light engine and the luminaire. The present disclosure further describes methods for crosswalk illumination using the bollard-style luminaires, and methods of communication between bollard luminaires. The bollard luminaire includes a design that generally confines light to illuminate the crosswalk and the pedestrian in the crosswalk, such that light that could produce glare for the pedestrian and/or a driver approaching the crosswalk is minimized.
Abstract:
An optical system comprises one or more lens elements (102, 103) for modifying a light distribution pattern, support elements (106) for securing the lens elements to a body structure, and elongated seal sections (108, 109) for constituting elongated sealing contact areas with the lens elements and with the body structure. Each support element comprises a sealing section (111) for constituting auxiliary sealing contact areas with at least one of the lens elements and with the body structure so that the auxiliary sealing contact areas constitute a ring-shaped sealing contact area surrounding at least one of end-sections (118, 119) of the lens elements. The sealing sections of the support elements and the elongated seal sections are capable of sealing spatial room limited by the lens elements and the body structure. The sealing achievable with the support elements makes it unnecessary to seal each of the lens elements separately.
Abstract:
A lighting device includes a housing, a light emitting device, and an optical array. The housing has a base and the light emitting device is connected to the base for producing a light output. The optical array includes a lens and removably connects to the base. The optical array is repositionable on the base to modify the light output.
Abstract:
An LED lighting array for illuminating an area with the lighting array comprising a plurality of LED devices set in conical or elliptically conical reflectors, each of which is mounted upon a plate, each of which may be set at various angles to one other, and each of which is backed by a series of elements, first a copper support element, then an optional layer of graphite foam, followed by an aluminum plate, and then an arrangement of copper fins operably lined to a thermal mass mate. The copper support element includes support planes that are off-set relative to each adjacent plate and are in at least three different planes relative to each other. The backing plates may efficiently dissipate heat produced by the LEDs. The apparatus can be mounted upon a stand to illuminate an area such as a portion of a car park, building entrance or the like.
Abstract:
A lighting fixture can comprise a rim or raised edge that extends peripherally around a recessed area. Light emitting diodes can be mounted in the recessed area and oriented to emit light out of the recessed area, towards an area to be illuminated by the lighting fixture. The lighting fixture can be mounted above the area, which may be outdoors, for example. A cavity can be formed inside the rim or raised edge. Circuitry for the light emitting diodes can be disposed in the cavity, so that the rim or raised edge encloses or houses the circuitry. The circuitry can comprise a light emitting diode driver, for example. The rim or raised edge can block emission of unwanted light, for example to function as a light pollution shield.
