An apparatus, manufacture and method of illumination support being a single monolithic substrate with light emitting diodes mounted on the external sides of the monolithic substrate. The necessary circuitry for the LEDs is embedded in one or more rigid or flexible electrical substrate that is affixed to one or more of the external sides of the monolithic substrate. The two terminal ends of the monolithic substrate are designed to fit into the lamp sockets of an existing or new light fixture without the use of end caps or end socket adapters, which provides structural support for the monolithic substrate.

A laser navigational system for a vehicle having a lighting assembly configured for emission of light. A lens array assembly receives incoming light from the lighting assembly and changes the direction of the incoming light received from the lighting assembly such that the outgoing light emanating from the lens array assembly is collimated in a first direction but diverges along a different, second direction. A scanning unit aligns with the lighting assembly to direct the collimated beam in two orthogonal directions. The lighting assembly, the lens array assembly and the scanning unit are configured to direct the light to form a visual beacon that guides navigation of the vehicle to a location.

An illumination assembly includes a polymeric substrate, an electrical circuit including two conductors supported by the polymeric substrate, an LED electrically coupled to the two conductors, and a heat spreader thermally coupled to the LED. The two conductors can be printed on the polymeric substrate, embedded within the polymeric substrate, or lie atop the polymeric substrate. The illumination assembly may be fabricated in three-dimensional form factors.

A LED grid device comprising a LED grid and a plate-shaped member at which the LED grid has been arranged. The LED grid has several electrically conducting wires arranged side by side, and several LED modules, each LED module having a LED package, wherein each LED package is coupled to at least two wires of the electrically conducting wires. Each LED module further has a thermally conducting element positioned between two adjacent wires of the wires that the LED package is coupled to. The thermally conducting element carries the LED package, and protrudes from the LED package, and the thermally conducting element is attached to the plate-shaped member.

A lighting device (30) and a method of manufacturing such a lighting device are provided. The lighting device comprises a sheet assembly (7), which comprises a substrate (1) being at least partly light transmissive, a plurality of light sources (5) coupled to the substrate. At least a portion of the sheet assembly (7) is fixed in a rolled-up arrangement so as to form a roll (12), whereby the light sources (5) in the portion of the sheet assembly (7) are arranged to emit light at least partly inwards in the roll and/or at least partly towards at least one end (31) of the roll. The present invention is advantageous in that it provides enhanced lumen density output, which makes the lighting device useful for high brightness applications, such as head lights and fluid purification.
