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.
