Abstract

A modular lighting device. The modular lighting device includes two or more LED modules. Each LED module further including a printed circuit board (PCB) and multiple LEDs mounted on a first face of the PCB. A heat sink is mounted on a second face of the PCB. Further, the modular lighting device includes a power supply. The two or more LED modules are coupled to each other.
