1. A lighting device, comprising:
- at least a first light emitter that emits light having a first color point;
at least a second light emitter that emits light having a second color point, the second color point different from the first color point;
at least a first sensor that detects brightness of at least light that is within 0.01 delta u′
, v′
of the first color point; and
at least a second sensor that detects brightness of at least light that is within 0.01 delta u′
, v′
of the second color point.

Abstract
A lighting device, comprising first and second light emitters that emit light having first and second color points, respectively, and first and second sensors that detect brightness of light within 0.01 delta u′, v′ of the first and second color points, respectively. A method comprising supplying energy to first and second light, emitters that emit light having first and second color points, respectively, and detecting brightness of light within 0.01 delta u′, v′ of the first and second color points, respectively.
