Lighting control techniques considering changes in eye sensitivity
First Claim
1. A lighting control system comprising:
- a lighting controller configured to control at least one lighting element;
a processor;
a lighting environment determination module executable by the processor and configured to determine a target light setting;
a light transition setting module executable by the processor and configured to compare the target light setting with an initial light setting and determine at least one light transition setting, the at least one light transition setting having a transitional color and transitional display time based on at least one of duration of exposure to, intensity of, and color saturation of the initial light setting; and
a lighting control module executable by the processor and for issuing light setting commands to the lighting controller, the lighting control module configured to command the at least one light transition setting prior to commanding the target light setting.

Abstract
Techniques are disclosed for manipulating both colored and tunable white lighting systems in order to enhance visual comfort and allow an observer'"'"'s eyes to recover from exposure to colored light. A lighting system may gradually adjust the color, color temperature, and intensity of various multi-chip LED panels in order to provide pleasant and acceptable changes in light settings. Instead of abruptly switching from one light setting to another, a lighting system may fade to an intermediate transition setting and subsequently fade to the final light setting, allowing an observer'"'"'s eyes time to adapt to the new light settings. In one example, switching from blue light to a neutral white light may involve a gradual fading from blue light, to a cool white light, and then to a neutral white light, thus allowing the end user'"'"'s eyes to adapt to the new light settings.

13. A method of controlling a lighting system comprising:
-
determining a target light setting for at least one LED panel; calculating a decrease in at least one color component between an initial light setting and the target light setting; calculating at least one transitional color having a larger proportion of the at least one decreased color component compared to the target light setting; calculating a transitional display time for each of the at least one transitional color, wherein the transitional display time is based on at least one of the duration of exposure to, intensity of, and color saturation of the initial light setting; displaying, via the at least one LED panel, light at the at least one transitional color for the corresponding transitional display time; and displaying, via the at least one LED panel, light at the target light setting. - View Dependent Claims (14, 15, 16, 17, 18)

19. A computer program product comprising a plurality of instructions non-transiently encoded thereon and executable by one or more processors to carry out the following process, the process comprising:
-
determine a target light setting for at least one LED panel; calculate a decrease in at least one color component between an initial light setting and the target light setting; calculate at least one transitional color having a larger proportion of the at least one decreased color component compared to the target light setting; calculate a transitional display time for each of the at least one transitional color, wherein the transitional display time is based on at least one of the duration of exposure to, intensity of, and color saturation of the initial light setting; display, via the at least one LED panel, light at the at least one transitional color for the corresponding transitional display time; and display, via the at least one LED panel, light at the target light setting. - View Dependent Claims (20)
