One purpose is to smoothly raise and lower a telescopic post used in a floodlight.

A floodlight according to the present invention includes: a telescopic post 2 that has a plurality of posts 21 to 25 whose outer diameters are made gradually smaller, into which the posts 21 to 25 can be loosely fitted, and that can be extended and contracted in an up-down direction; a lighting unit 3 attached to the post 25 located on the innermost side; a raising and lowering unit 26 that extends and contracts, in the up-down direction, the posts 21 to 25 in conjunction with each other; a base 4 that the post 21 located on the outermost side is fixed to; and dampers 27a, 27b that connect a side surface of the post 21 located on the outermost side and a side surface of the post 22 located on the second outermost side.

A site light including body, an arm coupled to the body having an adjustable arm length, a light assembly coupled to the arm opposite the body, and a drive mechanism with a crank arm rotatable about a first axis, where rotating the crank arm in a first direction causes the arm length to increase, and where rotating the crank arm in a second direction causes the arm length to decrease. The site light also includes a damper assembly in operable communication with the drive mechanism, where the damper assembly resists rotation of the drive mechanism when the crank arm rotates in the second direction, and where the damper assembly does not resist the rotation of the drive mechanism when the crank arm rotates in the first direction.

A mobile lighting device is disclosed with extendable boom sections. The boom sections are stored in a horizontal position and then pivot to a vertical position before being extended upward. A light section is positioned at the uppermost end of the last extendable boom section. A variety of safety features are also disclosed.

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 site light including a body, an arm coupled to the body having an adjustable arm length, a light assembly coupled to the arm opposite the body, and a drive assembly configured to alter the arm length. The drive assembly, in turn, includes a drive wheel mounted for rotation with respect to the body, an idle wheel mounted for rotation with respect to the body, and a biasing member configured to bias the idle wheel toward the drive wheel. The site light also includes a cable coupled to the arm where the cable is positioned between and engaged by both the drive wheel and the idle wheel.

A light tower assembly configured to rotate a light section from a first to a second position. In various embodiments, the light tower assembly comprises (a) a primary boom extending vertically from a base, (b) a light array boom supporting a light section on a frame rotatively mounted to the primary boom wherein the light array boom rotates around an axis of rotation, (c) a mounting assembly rotatively mounting the light array boom to the primary boom, and (d) a linear actuator assembly connected to the primary boom and the light array boom being configured to rotate the light array boom in one direction when the linear actuator extends and configured to rotate the light array boom in an opposite direction when the linear actuator assembly retracts.

A mobile lighting device is disclosed with extendable boom sections. The boom sections are stored in a horizontal position and then pivot to a vertical position before being extended upward. A light section is positioned at the uppermost end of the last extendable boom section. A variety of safety features are also disclosed.

A light tower includes a generator assembly including a prime mover, an alternator operably connected to the prime mover, the alternator configured to produce alternating current electrical energy, and a rectifier operably connected to the alternator and configured to convert alternating current electrical energy produced by the alternator to direct current electrical energy. At least one light emitting diode matrix is electrically connected to the generator assembly by an electrical connection, and a regulator is operably connected to the alternator and configured to detect a current of the direct current electrical energy in the electrical connection. In response to a detected current of the direct current electrical energy in the electrical connection, the regulator controls the alternator to adjust the current supplied to the at least one light emitting diode matrix.

A site light includes a body, an arm coupled to the body having an adjustable arm length, a light assembly coupled to the arm opposite the body, and a drive mechanism with a crank arm rotatable about a first axis. Rotating the crank arm in a first direction causes the arm length to increase. Rotating the crank arm in a second direction causes the arm length to decrease. The drive mechanism is adjustable between a first configuration, where the crank arm can only rotate in the first direction, and a second configuration, where the crank arm can be rotated in the first direction and the second direction.

A mobile lighting device is disclosed with extendable boom sections. The boom sections are stored in a horizontal position and then pivot to a vertical position before being extended upward. A light section is positioned at the uppermost end of the last extendable boom section. A variety of safety features are also disclosed.
