A light source includes a plurality of solid state light emitters configured to be powered directly from an AC source, and means for providing an electrically insulating and thermally conductive attachment between the solid state light emitters and a heat sink.

A portable building, the portable building including: a body having at least one wall that is adapted to move from a substantially vertical position to a second position; and at least one slideout portion that slides outwardly from the body. The body is substantially the size of an ISO shipping container in a transport configuration.

The invention relates to a prefabricated modular building system comprising a plurality of structural frames and connection means which horizontally and vertically join the structural frames, where the structural frames are hyperstatic and self-supporting with a closed cross-section and hyperstatic and self-supporting with an open cross-section. A building structure is formed with a plurality of structural frames interconnected horizontally and vertically in assemblies arranged such that, on the same level or on vertically arranged leveld, there is a sequence of assemblies of structural frames and empty spaces. The plurality of structural frames is horizontally and vertically connected and arranged on other structural frames in a vertical sequence of assemblies of structural frames and empty spaces.

A concrete modular element for use in a variety of building applications comprising: a slab, a ceiling, at least two walls, and a plurality of support beams. The walls comprise a proximal end and a distal end. The proximal end of each of the walls is connected to the slab while the distal end is connected to the ceiling. The slab and the ceiling both comprise a plurality of elongated sides. The slab, the ceiling, the walls, and the support beams integrally formed in a continuous concrete casting.

A portable building, the portable building including: a body having at least one wall that is adapted to move from a substantially vertical position to a second position; and at least one slideout portion that slides outwardly from the body. The body is substantially the size of an ISO shipping container in a transport configuration.

A structure which includes a rectangular base and two substantially U-shaped assemblies pivotally fixed to respective opposed longitudinal edges of the base, the assemblies being movable, relative to the base, into a compact configuration which is substantially of the shape and size of a conventional shipping container, and away from each other to an operative configuration at which the assemblies form walls and at least part of a roof of the structure.

A building assembly system that comprises thermoformed high density polyethylene molded components filled with high density polyurethane foam. The molded components are configured in a cube or triangle form and secured against a steel frame to provide a habitable constructed unit. The composition of the high density polyethylene molded components filled with high density polyurethane foam meets standards for the American Society for Testing and Materials for a habitable structure used by humans. The habitable structure can be used on land or water.
