A modular cube shaped light emitting diode (LED) luminaire that can be cascaded, or interconnected, to create a larger, higher power LED luminaire that produces more light than the modular LED luminaire is disclosed. Each modular LED luminaire comprises a housing, a heat sink, a power/control circuit board (PCB-A) and an LED circuit board (PCB-B). An optional fan and a metallic heat sink are also enclosed inside the modular LED luminaire housing/shell. The modular LED luminaire provides optical expansion across interconnected modular LED luminaires. The LEDs and heat sinks are easily removable for defect replacement, LED light replacement and upgrade, without uninstalling the entire luminaire. Secondary side processor control of the feedback regulator allows sensor, radio module, user inputs etc. to reside on the “safe” isolated (low voltage) secondary side of the supply can then be used to safely make changes (an allowable UL approval) in the regulated output drive to the LEDs. |

1. An LED luminaire assembly of a plurality of modular LED luminaires, comprising
a plurality of modular LED luminaires, each modular LED luminaire comprising:
a first printed circuit board, a heat sink and a second printed circuit board housed within a modular LED luminaire housing, the first printed circuit board comprising at least one programmable processor and a power supply, a plurality of PCB traces and a plurality of multi-conductor female connectors comprising a plurality of electrical terminals and plurality of recesses and the second printed circuit board comprising a plurality of light emitting diodes (LEDs) disposed thereon;
wherein the second printed circuit board is in thermal connection with the heat sink and further is in electrical connection with the first printed circuit board, wherein the LEDs are under electrical control of the processor of the first printed circuit board,a plurality of inter-module snap clips, each inter-module snap clip comprising a snap clip base and an open ring, each open ring comprising two tabs disposed at angles each open end of the ring and a V-shaped engagement mechanism formed by the angles of the two tabs,a plurality of inter-module posts attached to the modular LED luminaire housing, each inter-module post comprising a first end proximal to the side of the modular LED luminaire housing and a pair of recesses disposed at a distance further from the side of the modular LED luminaire housing than the first end, wherein the V-shaped engagement mechanisms of the inter-module snap clip are disposed in the recesses of the inter-module post. |
