A light source and a method for operating the same are disclosed. The light source includes a light emitter and a controller. The light emitter generates light in response to a control signal coupled thereto. The light emitter is characterized by an age related to the amount of light that has been cumulatively generated by the light emitter, the generated light for a given control signal changing with the age. The controller measures the age of the light emitter and generates the control signal based on the desired light intensity and the measured age of the light emitter. In one embodiment, the controller stores an age value for the light emitter, and the controller determines the control signal in response to an input signal specifying a desired light intensity from the light emitter, the controller updating the age value each time the control signal is determined.

Color management system

A light emitting device having a die that includes a light source that generates light of a first wavelength and a layer of phosphor particles covering the die is disclosed. The phosphor particles convert a portion of the light of the first wavelength to light of a second wavelength. The light source can be fabricated by attaching the light source to a substrate, and converting the light source by applying a light converting layer that includes a volatile carrier material and particles of a phosphor that convert light of the first wavelength to light of the second wavelength over the light source. The volatile carrier material is then caused to evaporate leaving a layer of the phosphor particles over the light source. A binder material can be incorporated in the volatile carrier for binding the phosphor particles to one another after the volatile carrier material is evaporated.

A light source is disclosed. The light source has a light-emitting chip that includes an LED that generates light in an active region thereof. The LED emits a light signal in a forward direction, and infrared radiation generated in the active region is emitted in a side direction in the form of a first infrared signal. The first light signal is determined by a first drive signal coupled to the LED. The light source also includes an infrared detector positioned to collect a portion of the infrared signal. The infrared detector generates a heat signal indicative of the amount of infrared radiation detected. A controller generates the drive signal so as to maintain the heat signal at a first target value. In light sources having LEDs that emit in different spectral ranges, the infrared detectors can all detect heat in the same spectral range.
