Abstract: A light sensor is disclosed that includes a photosensor; a memory; a communication interface; and a controller coupled with the photo sensor, the communication interface, and the memory. The controller may be configured to perform a number of operations. For example, the controller may be configured to sample from the photosensor a light intensity of light within a first spectral range at a non-task location within an architectural space; and determine a change in the first spectral range output of a light source to produce a desired amount of light within the first spectral range at a task location based on the sensed light intensity of the color channel at the non-task location. In some embodiments, the task location and the non-task locations are different locations within the architectural space. The controller may also be configured to transmit the change in the color channel output to a light source.

Abstract: Systems and methods are disclosed to translate a desired light level at a particular task location to a light level measured by a light sensor at a non-task location such as a wall location or a light switch location. For example, the light measured on the wall may be used to accomplish daylighting energy savings while maintaining a relatively constant illuminance value at the task location. Alternatively or additionally, up/down button presses at the wall location may be used to provide constant or consistent illuminance changes at the task location.

Abstract: Some embodiments include a remote for gesture recognition for an external light system. In some embodiments, the remote may include an acceleration sensor; a wireless transceiver; memory; and a processor communicatively coupled with the acceleration sensor, the wireless transceiver, and the memory. In some embodiments, the processor may be configured to: sample acceleration data from the acceleration sensor; determine a first event type based on the acceleration data; determine a second event type based on the acceleration data; determine a command for an external system based on the first event type; and transmit the command to the external device using the wireless transceiver. In some embodiments, the first event type and/or the second event type comprises an event selected from the list consisting of a swipe, a tap, a double tap, a directional point, and a tilt; exclude the second event type.

Abstract: Methods and systems herein provide for determining lighting contributions of light fixtures to an environment. In one embodiment, a system includes a light sensor and a controller. The light sensor generates light level data based on measured light levels. The controller determines a nominal light level based on the light level data, and identifies an optical burst pattern in the light level data generated by a light fixture. The controller then determines a lighting contribution of the light fixture based on the optical burst pattern and the nominal light level.

Abstract: Systems and methods are disclosed to control light output at one or more light fixtures based on input from one or more light detectors. Embodiments of the invention may also be used for auto commissioning, personal control and/or day lighting. Some embodiments of the invention can be used to ensure that light output at the light fixtures provides a combined uniform photometric distribution within an architectural space. Moreover, embodiments of the invention can respond to changes to ambient light, which illuminates the architectural space from a window, door, or television, etc., in a smooth and non-oscillating way. Embodiments of the invention can be implemented in lighting systems employing multiple light fixtures having one or more light source and multiple light detectors.
