Abstract: The present disclosure relates to a method of fabricating a thermoelectric device. The method includes disposing a metal layer on a dielectric layer to form a sub-assembly, forming patterned circuits on the metal layer, forming blind vias in the dielectric layer, fabricating first thermoelectric elements in a first series of blind vias, and fabricating second thermoelectric elements in a second series of blind vias to form thermoelectric units with the first thermoelectric elements and the patterned circuits. The sub-assembly is configured to be joined to an adjacent sub-assembly along a first direction, and the first and second thermoelectric elements of each thermoelectric unit are aligned in a second direction substantially perpendicular to the first direction. The present disclosure further relates to a thermoelectric device which includes a plurality of thermoelectric units forming a strip extending in a first direction.

Abstract: A lighting system comprising a light engine, a duct connected to the light engine defining a light transport passage for transporting light emitted from the light engine along a propagation direction through the duct, one or more light output surfaces on the duct through which light is emitted, the light engine comprising arranged sequentially in a single file: a light collimator having an output end arranged to face the light transport passage, a LED light source arranged to direct light into an input end of the light collimator, and a heat sink thermally coupled to the LED light source.
