One embodiment of the invention relates to a light tower. The light tower includes a base, an extendible mast coupled to the base, a light assembly coupled to the extendible mast and electrically coupled to the battery pack, and an inverter configured to receive and convert a direct current power from the battery pack into an alternating current power. The extendible mast is configured to move between a lowered position and a raised position.

A security light having optional connection to multiple power supplies. The lighting controller can sense the appropriate connected supply and automatically connect to three different power supplies which include house voltage connection through a typical junction box, a remote solar charging station, and on-board batteries that can be used as a third backup power supply. Additional implementations include power outage detection and backup illumination along with low voltage power supply from a mounting structure.

Tenon-mounted lighting fixtures with high structural integrity are provided. In one embodiment, the lighting fixture has a housing that has an integrally formed tenon cradle, which is configured to receive a tenon of a light pole. A light source is also mounted on a bottom side of the housing. The tenon cradle is between a first bolt boss and a second bolt boss, and is in communication with a rear opening of the housing. The first and second bolt bosses may be integrally formed in the housing. The tenon cradle includes multiple ribs. An arcuate cross rib resides in a first plane in which a first bolt shaft of the first bolt boss and a second bolt shaft of the second bolt boss reside. An axial rib intersects the arcuate cross rib and runs perpendicular to the first plane.

An area light is provided including a housing defining a central axis having a first end, a second end opposite the first end, and a side portion; a cover mounted on the first end of the housing; a light module disposed on the first end of the housing, the light module comprising a heat sink and at least one light-emitting diode (LED) to emit light through the cover and in a direction that extends 360 degrees around the center axis; and a battery receptacle disposed on the side portion of the housing to receive a removable battery pack and supply electric power form the removable battery pack to the at least one LED. At least one hook is provided on or adjacent the first end of the housing.

A site light including a body, a power system with an AC input and battery terminal, and a telescopic arm assembly supported by the body, where the telescopic arm includes a first end fixed relative to the body and a second end opposite and movable with respect to the first end. The site light also includes a light assembly in operable communication with the power system and coupled to and movable together with the second end of the telescopic arm, where the light assembly is operable in a first light mode in which the light assembly outputs approximately 13,000 lumens of light, and a second light mode in which the light assembly outputs approximately 20,000 lumens of light.

A lamp unit (100) for outdoor use is provided. The lamp unit comprises a gasket with a step-vise shape configured to provide a sealing effect in two perpendicular directions in order to prevent water ingress. The gasket is further configured to press a reflector (120) towards a lid element (130) in order to minimize the gap between them, thus ensuring a consistent lighting output.

A flagpole lighting assembly, including an enclosure which includes a ring-shaped base having an aperture therethrough which includes a circumferential region, and a bottom aperture interior to the circumferential region, and a cover which includes a top with an aperture therethrough, an outer wall circumferentially coupled to the top, with a larger diameter than a diameter of the circumferential region of the base, protruding downwards beyond the base, a primary protrusion extending from the top such that it is flush with the outer wall and including an aperture therethrough, and a plurality of secondary protrusions extending downward from the top, each protrusion having a brace connected to the outer wall, and a ring-shaped circuit board and a plurality of output lighted strands connected to the circuit board.

A method of operating a portable light including placing a base housing on a support surface, such that a plurality of legs are spaced away from the support surface and collapsed against an elongate body, grasping a portion of the portable light adjacent a light head with a first hand of a user and lifting the base housing away from the support surface, grasping the handle with a second hand of the user, depressing an actuator on the handle with the second hand, which removes a locking member from a locking recess of the elongate body to enable movement of the collar relative to the elongate body in a direction along a longitudinal axis, and sliding the collar along the elongate body away from the light head to move the plurality of legs to be obliquely angled relative to the elongate body.

A modular approach is provided for sensing and responding to detected activity or an event in a region that can be implemented quickly and easily using existing city infrastructure to establish a grid of sensors and detectors to provide localized or wide area coverage. The approach provides a turnkey solution or smart city in a box that can be adapted to different situations and needs to provide communications functionality and/or a desired or customized functionality for a wide range of different applications.
