A light source and a method of generating a light using the light source is disclosed. The light source is configured to produce a plurality of distinct colors in generating the light, one of the distinct colors falling within a blue spectral light band. A light controller modulates the spectral light produced by the plurality of distinct colors. The modulation provides melanopsin contrast in order to increase melanopsin responsiveness of a subject exposed to the generated light and maintains the color temperature, color quality, and color constancy experienced by the subject in a lit viewing environment within an acceptable range.

Temporally modulated multi-LED for enhanced subconscious physiological responses

A method for in-situ monitoring of gas-phase photoactive organic molecules in real time while depositing a film of the photoactive organic molecules on a substrate in a processing chamber for depositing the film includes irradiating the gas-phase photoactive organic molecules in the processing chamber with a radiation from a radiation source in-situ while depositing the film of the one or more organic materials and measuring the intensity of the resulting photoluminescence emission from the organic material. One or more processing parameters associated with the deposition process can be determined from the photoluminescence intensity data in real time providing useful feedback on the deposition process.
