The present disclosure sets forth a motion sensing outdoor security light with the flexibility of being mounted to either a wall structure or to an eave or ceiling structure. An adjustable spherical motion sensor housing may be provided with the rotationally adjustable outdoor security light, allowing easy adjustment of motion detection ranges under different mounting schemes without comprising the aesthetic design of the light. The adjustable spherical motion sensor housing may also provide an enlarged horizontal field of view for better performance. Sensitivity of a motion sensor may be adjusted via a control circuit based on adjustment of the spherical motion sensor housing.

A method of determining a drive signal provided to a light-emitting diode (LED). The method including sensing, via a first sensor, a first light intensity corresponding to a natural light in a room, sensing, via a second sensor, a second light intensity for a zone of the room, determining, via the controller, an expected light intensity, and determining, via the controller, whether the second light intensity exceeds the expected light intensity. The method further including, in response to determining that the second light intensity exceeds the expected light intensity, determining, via the controller, an artificial light intensity, determining, via the controller, the drive signal based on a desired light intensity for the zone of the room, the artificial light intensity, the first light intensity, and the second light intensity, and controlling, via the controller, the driver to provide the drive signal to the LED array.

A light fixture can be electrically connected to a module that can add certain functionality and/or alter the way the light fixture is controlled. A module base includes a module receiver configured to receive one of a plurality of modules. At least the module base is connected to input power. When a first module is coupled to the module base, the combination of the light fixture and module has a first range of functionality dictated at least in part by the functionality of the first module. When the first module is removed and replaced with a second module, the combination of the light fixture and the module has a second range of functionality dictated at least in part by the functionality of the second module.

The present invention provides a lighting fixture and lighting system for automatically adjusting a color temperature. The optimal color temperature is obtained by adjusting step by step using the light intensity, the infrared movement signal, the visibility, the human body temperature and the environment temperature. Specifically, the color temperature is compensated for and adjusted by the light sources of at least two light emitting units. In this way, the adjustment range of the color temperature is extended, making it possible to obtain the optimal color temperature.

A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.
