Abstract: Example embodiments relate to compact luminaire heads. One example luminaire head includes a thermally conductive metal body that includes a plate-like portion, a tube portion, and at least one cooling fin. The plate-like portion extends in a longitudinal direction of the metal body and having a flat first surface and a second surface opposite the first surface. The tube portion extends in the longitudinal direction at the second surface. The at least one cooling fin extends away from the second surface adjacent to the tube portion. The luminaire head also includes at least one support substrate with a plurality of light emitting elements. The at least one support substrate is arranged against the first surface. The tube portion is shaped to receive in a first open end thereof a rigid cylindrical end portion of a mounting base, such as a pole for the luminaire head.

Abstract: Example embodiments relate to modular luminaire assemblies for tunnels. One example luminaire assembly includes a plurality of interconnectable modules. The plurality of interconnectable modules includes at least an electronic module and at least a first optical module. The first optical module include at least one printed circuit board that includes at least one corresponding LED array and at least one corresponding optical plate. The electronic module includes driver circuitry for driving the at least one LED array of the at least one printed circuit board. The first optical module includes a tray containing the printed circuit board and the optical plate, and an at least partially light transmitting cover closing the tray. The tray has a bottom face and a first edge between the cover and the bottom face. The electronic module includes a tray containing the driver circuitry and a cover closing the tray.
