摘要： A light source and method for programming the light source to provide a color that approximates that of a target light source are disclosed. The light source generates light at first and second wavelengths with intensities that are determined by first and second control signals that are set by a feedback controller that matches the outputs of a monitoring circuit to target signals. The target signals are generated from target values that are entered into the feedback controller by exposing the light source to the target light source and observing the outputs from a set of photodetectors incorporated in the light source. In one embodiment, the photodetectors in the monitoring circuit are used for this programming function.

摘要： A light source and method for making the same are disclosed. The light source includes a plurality of LEDs mounted on a substrate and a sensor for measuring light from the LEDs. Each LED emits light having a different spectrum from the other LEDs, the average intensity of light from that LED being determined by a drive signal coupled to that LED. The sensor generates a plurality of signals, each signal being characterized by a sensor value that is proportional to the intensity of light emitted by a corresponding one of the LEDs. A controller generates the drive signals and stores a current target value for each LED. The drive signals for each of the LEDs is generated such that the sensor value for that LED matches the stored current target value for that LED.

摘要： A light source having first and second phosphor-converted component light sources is disclosed. The first component light source includes a first LED that emits light at a first wavelength and a first luminescent conversion material layer that converts light of the first wavelength to light of a first output wavelength, and the second component light source includes a second LED that emits light at a second wavelength and a second luminescent conversion material layer that converts light of the second wavelength to light of a second output wavelength that is different from the first output wavelength. The first and second LEDs are constructed in the same material system, preferably in the same batch of wafers on the fabrication line. A controller generates a current through each of the first and second LEDs that results in the light source generating light that is perceived to be a predetermined color.

The first and second component light sources include LEDs that emit light of a first wavelength and a layer of a light converting material that converts a portion of that light to light of a second wavelength. The interface circuit powers the first and second component light sources such that the solid state light source has a color point that is closer to the black body radiation curve than either the first or second color points. A third component light source can be included to expand the range of white color temperatures that can be reached by the light source.
