Abstract:
1. A distributed control network for a transit vehicle lighting system, comprising: a plurality of LED-based lighting fixtures, each of said LED-based lighting fixtures comprising a plurality of light-emitting diodes (LEDs) for illuminating an area of a transit vehicle arranged in a linear array and flanked by a pair of reflective sidewalls angled outwards from the linear array and forming a cavity with the linear array at the base thereof, with a diffusive light-transmissive cover disposed over the cavity; a plurality of slave nodes for controlling the LED-based lighting fixtures; a master node in communication with said slave nodes; a battery power source coupled to said master node; a digital communications bus for communicating among the master node and the slave nodes; and a power bus interconnecting said master node and slave nodes; wherein said power bus is integrated with the digital communications bus in a plurality of power/data cable segments; wherein said master node is communicatively coupled to said slave nodes by connecting said slave nodes in a daisy chain using with said power/data cable segments; and wherein power derived from said battery power source is conveyed from said master node to said slave nodes through the power/data cable segments.
