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.
