There is provided a mounting bracket for attaching a light fixture to a light pole, with the light pole having an external surface, an internal surface defining an internal cavity, and a pair of apertures extending from the external surface to the internal surface. The mounting bracket includes an internal support sized and structured to be insertable within the internal cavity of the light pole. The internal support includes a housing and a pair of fasteners moveable relative to the housing and alignable with respective ones of the pair of apertures. An external support is sized and structured to be positionable adjacent the external surface of the light pole, the external support having a pair of slots formed therein and alignable with respective ones of the pair of fasteners. A mount body is slidably engageable with the external support and is pivotally connectable to the light fixture.

A lighting fixture includes a support frame, a light head, a light source, an angle sensor, and a controller. The light head is pivotally connected to the support frame. The light source is disposed on the light head. The angle sensor is disposed on the light head and configured to sense a rotation angle of the light head. The controller is electrically connected to the light source and the angle sensor. The controller selectively adjusts a light emitting parameter of the light source according to the rotation angle.

An angle adjustment device of an embodiment includes a first rotational unit and a spring member. The first rotational unit is supported by a frame body, and rotationally moves around a first rotating shaft that passes through the frame body and that is disposed along an opening surface of the frame body, by a driving force of a driving source with an object to be operated. The spring member urges the first rotational unit in a single direction of a rotational direction.

Systems and methods for collapsible lighting fixtures are disclosed. In aspects, a horticultural luminaire 100 has first and second light fixtures 110, 120 coupled in movable relation between storage and deployed positions by a coupling element 130 applying a retarding torque. Coupling element can be coupling shaft 250 providing friction, or friction hinge cartridge 260. In aspects, hinge 130 has ledge surfaces 218, 228 adjacent rotational hinge faces 216, 226 and extending transverse the rotational plane. In aspects, a horticultural luminaire has an articulated cableway extending through hinge 130 coupling light fixtures 110, 120 and guiding a cable entering from the exterior into cable passageways in light fixtures 110, 120, thereby lessening a cable pinch point during rotation and deployment.

A bumper assembly includes a bumper and a stowable lighting assembly. The stowable lighting assembly includes a post and a lighting device. The post includes a proximal end and a distal end, wherein the proximal end is pivotably coupled to the bumper. The lighting device is pivotably coupled to the distal end of the post. The stowable lighting assembly is moveable between a stowed position and a deployed position, wherein the post positioned within or beneath the bumper in the stowed position.

A stable base supports a handle portion of an emergency light. The stable base has three legs which can be placed selectively in any of three configurations. In a first configuration, the legs are generally transverse to an axis of the emergency light handle, to form a tripod-like support on approximately level ground. In a second configuration, the legs are disposed downwardly so as to be generally parallel to the axis of the handle portion, such that the tips of the legs are disposed downward and are adapted to be inserted into the ground to resist high winds and gusts. In a third configuration, the legs are raised upward such that the tips of the legs are disposed adjacent to the handle portion of the emergency light, and are adapted to be inserted into a container for storage or shipping.
