A transportable lighting system. The lighting system is designed to withstand the difficult and extreme weather conditions typically experienced in outdoor work sites such as drilling rig environments. The pulley and roller arraignments are designed for minimal friction. The overall pulley and roller design for the lifting of the unit (including the way the cables are orientated) is extremely robust. The outrigger includes fold out and lock in place design. The power source can run a duel transfer switch setup powered by an external supply (like drilling rig power) or from its own 100% back-up generator. Lighting used is typically light in weight and bright. Towers are skid mounted and mobile, e.g., with the use of a truck. Individual lights can swivel and tilt as can the entire bank of lights.

A light tower includes a base, an extendible mast coupled to the base, a battery pack supported on the base and including a plurality of lithium-ion battery cells, a light assembly including a plurality of light emitting diodes electrically coupled to the battery pack, a display configured to receive inputs and display information, and a controller in communication with the battery pack, the light assembly, and the display. The configured being to: receive a light intensity change input from the display, change a power provided by the battery pack to the light emitting diodes in response to the light intensity change input, and display on the display a change in runtime resulting from the change of the power provided by the battery pack to the light emitting diodes.

A hybrid light tower includes an engine, a permanent magnet generator configured to be driven by the engine, a battery pack including a plurality of lithium-ion battery cells, an extendible mast configured to move between a lowered position and a raised position, 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. The light tower does not include a battery charger connected to the battery pack.

A solar and fuel powered portable light tower includes a portable base, a light panel arm, a primary power source, a secondary power source, and a control box. The light panel arm, that includes a plurality of light panels, is connected to the portable base while the primary and secondary power sources are positioned within the portable base. The control box, which is positioned within the portable base, controls the solar and fuel powered portable light tower. An insulated wall within the portable base separates the primary power source and the secondary power source for safety purposes. The plurality of light panels is preferably powered the primary power source that includes a plurality of photovoltaic panels and batteries. The plurality of light panels is also powered by the secondary power source that also acts as an onsite generator.

The present invention is directed to a mobile light tower that utilizes multiple sources of energy to provide a highly energy efficient source of illumination. The lights of the light tower draw power from the energy stored in the batteries. During the day, solar energy can captured and stored in batteries. In times of cloud cover, or at night, wind energy can be captured and stored in the batteries. Additional alternative energy sources can also be incorporated. In the event that neither of these sources are sufficient, a fuel powered generator can be utilized to generate energy to be stored in the batteries.
