Pluggable radio navigation satellite system street light controller
First Claim
1. A street light controller, comprising:
- a radio navigation satellite system (RNSS) receiver;
a first electrical interface; and
a lamp controller,wherein the first electrical interface is adapted to couple with a second electrical interface of a street light and the lamp controller is adapted to regulate a supply of power to a lamp of the street light via the first electrical interface based at least in part on time information and position information received from the RNSS receiver, wherein the street light controller is adapted to draw power via the first electrical interface and wherein the first electrical interface comprises a plug.

Abstract
An RNSS based street light controller pluggable into a standard electrical interface of a street light for drawing power and controlling a lamp of the street light eliminates the need for photosensors, wiring terminals and related components and yields a street light controller with modest installation and configuration requirements and robust performance and failure recovery characteristics. In some embodiments, the RNSS based street light controller comprises an RNSS receiver, a first electrical interface and a lamp controller, wherein the first electrical interface is adapted to couple with a second electrical interface of a street light and the lamp controller is adapted to regulate a supply of power to a lamp of the street light via the first electrical interface based at least in part on information received by the RNSS receiver.
