<p>A light module (21) comprises: a housing support; a voltage/current supply line (V) and a ground line (G) each having a first end and a second end and supported by the housing support; a first control line (CTL1) and a second control line (CTL2) each supported by the housing support and having a first end and a second end; a controller (23) having a first connection to the second end of the first control line, at least one current switching input, and a second connection to the first end of the second control line, and a power input connected to the voltage/current supply line (V), a ground connection connected to the ground line (G), the controller (23) configured to control access of the current switching input to the ground line (G); at least one light emitting diode (25,27,29,31,33,33) having a current input connected to the voltage/current supply line (V) and a current output connected to a corresponding current switching input of the controller (23). A modular light system (51) comprising a multiplicity of the above light modules (21) and a master system comprising a plurality of the modular light systems (51) are also provided.</p> |
