Sensor housings, modules, and luminaires comprising the same are provided. The sensor housings and modules set forth herein have improved heat sinking abilities for dissipating heat from a sensor while simultaneously facilitating thermal isolation of the sensor. Briefly, a sensor housing described herein comprises a cavity for housing a sensor and a heat sink. The heat sink is configured to dissipate heat from the sensor housing and thermally isolate the sensor housing from other heat generating components, such as other portions of a luminaire.

A vertically disposed HID lamp fixture for growing plants, which includes a housing having an interior, an exterior, a top hole, and a lower lip defining a light opening towards the plants, further including an inlet duct and outlet duct for the forced air cooling embodiment, a socket tower having an upper flange and a lower flange, the upper flange affixed around the perimeter of the top hole securing the socket tower to the housing, a reflector having an aperture, the lower flange affixed around the perimeter of the aperture suspends the reflector within the housing such that an isolation chamber is formed between the exterior side of the reflector and the interior of the housing, a HID lamp removably engages within said socket tower longitudinally extending substantially downward and through said aperture vertically disposed above said light opening sealed by a compressively held glass sheet.

A system for upgrading and retrofitting existing streetlights. The system enables conventional streetlights using sodium vapor, and other conventional lighting technologies, to be upgraded to more energy efficient and long-lasting LED lighting. At the same time, cellular and wireless communications can be added to the streetlight to provide additional bandwidth over that provided by conventional cell towers. The system can offload bandwidth in otherwise overloaded areas, such as densely populated urban areas. The system can include mini- or micro-cellular routers, GPS, Wi-Fi, Bluetooth®, and other micro cellular and wireless technologies. The system can include a light fixture styled to look like existing conventional light fixtures and can be retrofitted to existing streetlight poles and mounts with little, or no, modification to the pole and wiring.

Techniques are described for using an integrated lightbulb camera system for monitoring a property. The integrated lightbulb camera system can have a housing that includes one or more cameras, a power-line communication (PLC) chip, and one or more processors. The PLC chip can be configured to enable communications between the lightbulb camera system and one or more external devices. The one or more processors can be configured to control the one or more cameras to capture one or more images and control the PLC chip to transmit at least one of the one or more captured images over a power-line to at least one of the one or more external devices. The integrated lightbulb camera can also have a lightbulb compatible screw base that is configured to mount the housing to a lightbulb socket and accept electrical current that is provided to the housing.
