Abstract:
1. A light emitting system comprising: a light emitting module including a first light emitting device (LED) package, a second LED package and a third LED package, the total light emitted by the module comprising light emitted by the first, second and third LED packages, wherein: a memory module affixed proximal to the light emitting module, wherein predetermined calibration parameters for the light emitting module are registered on the memory module; a light sensor oriented to measure the color chromaticity properties of at least part of the total light emitted by the light emitting module; and, a control system for managing activation properties of at least one of the first, second, and third LED packages when activated, the control system being coupled to the light sensor and adapted to provide feedback to modify activation properties of the at least one of the first, second, and third LED packages to achieve a predefined color chromaticity and color rendering index (CRI) parameter for the total light emitted by the light emitting module.
