Luminaire with socket with prevention of water ingress
According to certain embodiments, an apparatus comprises a housing including a cavity; a socket disposed in the cavity, wherein the socket makes direct contact with a portion of the housing surrounding the cavity; a surge protector disposed on the socket, wherein the surge protector comprises a male interface plugged into the socket, and female interface; and a photocell plugged into the female interface.
1 . A luminaire comprising:
a housing including an integrated protruding ring with a cavity;
a socket disposed in the cavity, wherein the socket makes direct contact with a portion of the ring surrounding the cavity, and wherein the socket includes an interchangeable interface;
an external electronic device configured to mate with the socket and utilize the standardized interface; and
wherein the protruding ring is configured to receive the external electronic device and wherein the external electronic device is configured to cover at least a portion of the protruding ring to form a seal around the protruding ring to reduce or eliminate water ingress into the socket, without a gasket between the protruding ring and external electronic device.
2 . The luminaire of claim 1 , wherein the housing is formed of injection molded plastic.
3 . The luminaire of claim 1 , wherein the socket comprises a National Electronics Manufacturers Association (NEMA) interface, the NEMA interface includes a NEMA male interface, and a NEMA female interface, and wherein the NEMA male interface is plugged into the socket.
4 . The luminaire of claim 1 , wherein the socket includes:
a Zagha interface; and
a Near Field Communication (NFC) circuit, configured to transmit and receive NFC signals; and
the apparatus further comprising:
a driver disposed in the housing, the driver connected to an NFC transceiver configured to transmit and receive signals from the NFC circuit of the socket.
5 . The luminaire of claim 4 , wherein the driver has an auxiliary input voltage signal 2 , and wherein the NFC transceiver induces power to the NFC circuit of the socket.
6 . The luminaire of claim 5 , wherein the NFC transceiver transmits Digital Addressable Lighting Interface (DALI) signals to the NFC circuit of the socket.
7 . The luminaire of claim 6 , further comprising a sensor, and wherein the NFC circuit of the socket communicates DALI signals received from the NFC transceiver to the sensor.
8 . The luminaire of claim 1 , wherein the external device is a surge protector, a photocell control, a shorting cap, or a control device.
9 . The luminaire of claim 1 , wherein the socket is disposed into the cavity by one or more of clipping, ultrasound, glue, and screwing with threads.
