Abstract: A plurality of interconnectable modules includes an electronic module and a first optical module. The first optical module includes a tray with a bottom surface and a side surface, a LED array provided on a printed circuit board disposed on the bottom surface, and an at least partially light-transmitting optical cover closing the tray. The electronic module includes a housing with a bottom wall and a sidewall, a LED driver circuitry for driving the LED array of the printed circuit board, and a door closing the housing. The side surface includes a first electrical connector and a first mechanical connector and the sidewall includes a second electrical connector and a second mechanical connector. The first and second electrical connectors are cooperating to electrically interconnect the electronic module to the first optical module, while the first and second mechanical connectors cooperate to mechanically secure them together.

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.

Abstract: Described herein is an LED module (500) comprising a PCBA (200) having an array of LED elements, a secondary lens array (300) and a lens holder (510). The secondary lens array (300) has a peripheral lip (360) and a plurality of boss portions (330a) which are compressed between the lens holder (510) and the PCBA (200) to form water-tight gaskets. The secondary lens array (300) also forms gaskets around wires connecting with terminal blocks on the PCBA (200) and effectively seals with a base plate (100) on which the PCBA (200) is mounted.
