    摘要: A method implemented by a communication device for controlling light emitted from a linear lighting device comprising a plurality of linearly distributed controllable light sources, the method comprising: displaying an image on a display of the communication device; receiving an input indicating an area of the image; analyzing the image area to derive a sequence of colors; generating a control signal based on the derived 5 sequence of colors; and transmitting the control signal to the linear lighting device to control the plurality of controllable light sources to emit light in accordance with the derived sequence of colors.

    摘要: Disclosed are lighting devices (102), luminaires, lighting systems, lighting modules (104), and methods of controlling the same are taught herein. In various embodiments, a lighting device (102) may include a light source such as an LED (118) configured to emit light towards a targeted portion (106) of a surface (108). An LED driver (120) may be configured energize the LED in response to a compensated signal (132). A light sensor (122) may be configured to measure light reflected from the targeted portion of the surface and to generate a reflected light signal (128) that represents one or more properties of the reflected light. A controller (116) may be operably coupled with the LED driver and the light sensor. The controller may be configured to generate the compensated signal based on the reflected light signal and an input signal (130) that represents one or more desired properties of light to be reflected from the targeted portion of the surface.
