    摘要： Some embodiments include a method of operating a tunable light module. The method can include driving a lamp in the tunable light module, having lamps of at least two colors, to produce a colored light according to the color mixing plan that corresponds to a correlated color temperature (CCT); measuring a light characteristic of the lamp using a light sensor; detecting a degradation level by comparing the measured light characteristic against an expected light characteristic; and adjusting a current level for driving the lamp at the CCT by referencing the color mixing plan and an alternative coefficient corresponding to the degradation level.

    摘要： A method for communication between a lighting node and a controller is described. One embodiment of the method includes transmitting a command from the controller based on a target illumination profile stored on the controller to the lighting node utilizing a controller radio device and receiving the command from the controller at the lighting node utilizing a node radio device. The method may also include generating illumination having a spectral content from the lighting node utilizing at least a light emitting diode; and receiving the spectral content from the lighting node at the controller utilizing an optical sensor.

    摘要： Introduced here are light sources for flash photography configured to produce high-fidelity white light that is tunable over a broader range of correlated color temperatures (CCTs) than conventional flash technologies. The light source can include multiple independently controllable color channels representing illuminants (e.g., light-emitting diodes) of different colors with varying degrees of saturation. Operating collectively, the multiple color channels can produce a high spectral quality white light corresponding to different CCTs (e.g., “warm” white light having a red hue, “cool” white light having a blue hue). Operating independently, these same color channels can be pre-flashed in a variety of prescribed sequences to probe the spectral characteristics of a scene, thereby allowing for an enhanced, spectrally matched white flash as well as collecting per-pixel reflectivity data that can be later used in during post processing of the captured image.

    摘要： Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each color channel of the multi-channel light source (which is configured to produce a flash), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the flash). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

    摘要： A light source apparatus is disclosed. The light source includes an array of light emitting diodes (LEDs) including at least three color channels, the at least three color channels includes: a yellow-greenish channel including a YAG:Ce phosphor emitter pumped by a royal blue InGaN LED; a red channel including a second LED, the second LED being either phosphor-based LED or AlInGaP LED; and a blue green channel including a third LED wherein the third LED is a royal blue InGaN LED. The light source further includes a mixing barrel around the array of LEDs for mixing light generated from the three color channels to simulate a black body radiator at different correlated color temperatures. Each of the at least three color channels includes one or more LEDs emitting the same color.

    摘要： Lighting and control systems and methods for a lighting node and a remote control device are disclosed. The remote control device may be coupled to the lighting node via an identification process, such as broadcasting an identification request from the remote control device to nearby lighting nodes. The lighting node can respond to the identification request by sending an identifier to the remote control device such that future commands sent from the remote control device is limited to be responded by the lighting node having the identifier stored thereon. Once coupled, the remote control device can adjust spectral content produced by the lighting node based on user-configuration or a color profile captured via an optical sensor. The adjustment via the remote control device may further include calibration and recalibration of the lighting node utilizing a feedback mechanism with the optical sensor.
