A hybrid light tower includes an engine, a generator configured to be driven by the engine, a battery pack, a mast, and a light assembly including a plurality of light emitting diodes. The generator is configured to produce a first DC power. The battery pack is directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack. The light assembly is coupled to the mast and the light emitting diodes electrically coupled to the battery pack to receive a second DC power from the battery pack.

A portable solar powered illumination system has a housing adapted for transport using at least one pair of wheels coupled to an axle assembly. The housing has a rear facing wall that extends at a selected non-orthogonal angle with respect to a base of the housing. The rear facing wall supports a tri-fold solar panel assembly with first, second and third solar panels. The first solar panel is affixed to the rear facing side wall, and the second and third solar panels hingedly fold onto and away from the first solar panel between retracted and deployed positions. Energy collected by the solar panel assembly is stored by an energy storage device during the day and used by a light assembly for illumination at night. An elevation adjustment device establishes a rotational angle of the housing to maintain the deployed solar panels at a desired angle.

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.

Expandable light towers suitable for mounting to a mobile unit, and methods for their use. Such an expandable light tower includes a telescoping assembly comprising first and second telescoping units. The second telescoping unit is telescopically received in the first telescoping unit to configure the expandable light tower to have retracted and extended configurations. The light tower further includes a light-mounting assembly mounted to the second telescoping unit and a mounting assembly coupled to the first telescoping unit and adapted to mount the telescoping assembly to a hitch of a mobile unit. The mounting assembly enables the telescoping assembly to pivot about a transverse axis.

A portable lamp comprises a central body, a boom arm, flat tripod stand, and a light unit. The central body is extendable along its vertical axis to a predetermined length. The boom arm is of adjustable length and is rotatably fixed to the upper end of the central body with a positively locking elbow joint, including a ratchet and pawl. The lower end of the central body is fixed with a foldable locking flat tripod stand adapted to hold and provide mobility to the portable lamp. Flat tripod stand includes a spring-biased latch and detents that hold legs in a folded or a down position. The central body, the boom arm, the tripod stand and the light unit are configured to provide up to twelve degrees of freedom jointly.

Disclosed is a compact portable light tower that can be stacked or nested. The light tower employs a scissors lift mechanism to raise a set of bar lights from a housing having a height of about 28 and a length of about 60, to an extended height of about 360. The scissors lift is extended and retracted by use of a linear actuator. Batteries or an engine/generator assembly is employed for operation of the actuator and light bar. The housing can be stacked for ease of storage and transportation. Outriggers provide stabilization of ground engagement.
