Abstract
Power over Ethernet power sourcing device is provided inside a light fixture to enable a communications interface and provide electrical power to devices such as cameras, rain sensors, chemical sensors, wireless data uplink units, and other power over Ethernet powered devices. The power over Ethernet system is especially adapted for use in LED street lights and must be able to operate from a wide AC voltage supply range that is typically found in these types of lights.
Claims30
A device comprising:
- (a) a housing, said housing having at least one light receptacle for receiving and providing power to one or more light units;
- (b) a connection for receiving power from an external power source;
- (c) said housing having one or more external peripheral bus receptacles to which one or more external powered devices may be operatively connected;
- (d) one or more internal peripheral bus receptacles within said housing, said internal peripheral bus receptacles providing a releasable operative connection for the attachment of one or more internal powered devices;
- (e) a power over Ethernet power sourcing device within said housing, said power over Ethernet power sourcing device operatively connected to said connection for receiving power from the external power source and selectively configured to output power and data over an Ethernet connection to:
- (i) one or more of said internal peripheral bus receptacles, and
- (ii) one or more of said external peripheral bus receptacles;
- (f) a wireless telecommunications device within said housing, said wireless telecommunications device having a data connection to said power over Ethernet power sourcing device and a power input connection for receiving power;
- and
- (g) a microcontroller unit within said housing, said microcontroller unit having a data connection and a power connection to said power over Ethernet power sourcing device, said microcontroller unit for controlling the power and data channeled to said Ethernet connections of said power over Ethernet power sourcing device.
