A lighting arrangement comprises a carpet structure and a control unit. The carpet structure includes a carpet back lighting system comprising a carpet back lighting unit having a lighting unit front face and a plurality of light sources. The carpet structure further includes a light transmissive carpet unit comprising a carpet unit front face and a carpet unit back side. The lighting unit front face and the carpet unit back side are adjacent. The carpet unit is arranged to transmit at least part of the light travelling in a direction from the carpet unit back side to the carpet unit front face. The control unit is configured to receive one or more input signals and is configured to generate, in response to one or more input signals, one or more output signals to control the light generated by the light sources.

A raised pavement marker (RPM) is sized and configured to comply with Department of Transportation requirements and includes a main body with a top side, opposite angled side faces, opposite ends and a bottom surface structured to be bonded to a road surface. A sheet substrate is coated on a top surface with multiple layers of a photoluminescent composition containing one or more rare earth materials that emits a highly visible glowing light in dark or near dark conditions for at least 6 hours when fully charged. The sheet substrate is inserted within a recessed pocket on the top side of the RPM with the photo-luminescent top surface facing up and is covered by a transparent acrylic lens that is electronically welded to the main body to provide an integral one piece sealed structure. The opposite angled side faces may be fitted with prismatic reflective lenses.

A lighting device includes a lighting source, a case, and a light adjuster adjusting a path of light emitted from the lighting source. The light adjuster includes a first light adjustment panel, a second light adjustment panel, and a shielding panel. The first light adjustment panel is placed between the first reflection panel and the second reflection panel, and shields a part of the light emitted from the first lighting source. The second light adjustment panel is placed between the third reflection panel and the fourth reflection panel, and shields a part of the light emitted from the second lighting source.

A collision avoidance system includes a sensor adapted to detect at least one vehicle in the vicinity of a predetermined area and generate target data relating to the at least one vehicle. An awareness engine receives the target data and evaluates the target data for a threat of a collision. An alerting system is adapted to alert the at least one vehicle in the event of a threat of a collision, the alerting system being activated by the awareness engine.

A lighting element for an illuminated hardscape. The lighting element includes a body structure defining a dispersion surface. A light fixture is positioned within the body structure and is configured to provide a light which is dispersed through the body structure to the dispersion surface. The body structure is formed from a clear or translucent material. An illuminated hardscaping is also provided.

A method and device for easily installing and removing an airport light on a runway using a fixture ring having a base ring; an annular lip operatively connected to and extending radially inwardly from the base ring; a lift bar operatively connected to the annular lip and extending from one side to the diametrically opposite side of the annular lip; and an extractor, operatively connecting the lift bar to the annular lip to cause the lift bar to move up and down relative to the annular lip.

An apparatus and system for mounting an exterior illumination fixture to the roof of a building or other structure. Certain aspects of the present disclosure provide for a roof-mounted attachment apparatus comprising a metal plate comprising one or more apertures (i.e., nail holes) and at least one fastener extending through the metal plate. In certain embodiments, the at least one fastener is coupled to the metal plate such that the lower surface of the metal plate sits flush when installed on a surface of a roof. In accordance with certain aspects of the present disclosure, an exterior illumination fixture is configured to be coupled to the upper surface of the metal plate via the at least one fastener to enable one or more exterior lighting applications.

A thoroughfare lighting device includes a housing to be attached to a thoroughfare surface, and including sidewalls that taper. A plurality of light-emitting diodes (LEDs) selectively illuminate individual lanes, including a first set of LEDs to emit a generally white light, and a second set of LEDs to emit colored light that is observable by an observer. A driver circuit operates the second set of LEDs to emit colored light illuminating a single lane indicating a condition of the individual lane. Optics may be carried by the housing and positioned in optical communication with at least a portion of the plurality of LEDs. A traffic sensor communicatively coupled to the driver circuit and configured to sense a traffic pattern and generate information regarding traffic on the associated thoroughfare. The driver circuit is configured to operate the plurality of LEDs responsive to the information generated by the traffic sensor.

A collision avoidance system includes a sensor adapted to detect at least one vehicle in the vicinity of a predetermined area and generate target data relating to the at least one vehicle. An awareness engine receives the target data and evaluates the target data for a threat of a collision. An alerting system is adapted to alert the at least one vehicle in the event of a threat of a collision, the alerting system being activated by the awareness engine.

A method and device for easily installing and removing an airport light on a runway using a fixture ring having a base ring; an annular lip operatively connected to and extending radially inwardly from the base ring; a lift bar operatively connected to the annular lip and extending from one side to the diametrically opposite side of the annular lip; and a pair of extractors, operatively connecting the lift bar to the annular lip to cause the lift bar to move up and down relative to the annular lip.
