US 2012/0235600 A1 · METHOD OF OPTIMIZING LIGHT OUTPUT DURING LIGHT REPLICATION

Abstract

A method of utilizing a light replication luminaire to match the spectral characteristics of light that is output from the luminaire to the spectral characteristics of a target light spectrum is provided. In one example, the method permits the user to assign a weight to one or more characteristics of the target light spectrum to be replicated. A best approximation of the target light spectrum is then determined, taking into account the weight assigned to each characteristic. In another example, the target light spectrum is provided to the luminaire by the user through the specification of various characteristics of the target light spectrum.

Dependent claims

A method of replication of light by a luminaire, the luminaire comprising a plurality of light sources, the method comprising:

providing a target light spectrum to the luminaire;
defining a replication objective by assigning a relative importance to matching at least one characteristic of the target light spectrum;
determining driving conditions for each light source to provide an approximated light that meets the replication objective;
and
driving each wavelength channel at the driving conditions.
