摘要： A light source and method for controlling the same. The light source includes a first component light source that includes N LEDs, a photo-detector, and a collector, where N>1. Each LED has a light emitting chip in a package. The light emitting chip emits light in a forward direction and light in a side direction. The light generated in the forward direction is determined by a drive signal coupled to that LED. A portion of the light in the side direction leaves the package. The collector is positioned such that a portion of the light in the side direction that leaves the package of each of the LEDs is directed onto the photo-detector. The photo-detector generates N intensity signals, each intensity signal having an amplitude related to the intensity of the light emitted in the side direction by a corresponding one of the LEDs.

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 device and method for emitting composite output light uses multiple wavelength-conversion mechanisms to convert the original light generated by a light source of the device into longer wavelength light to produce the composite output light. One of the wavelength-conversion mechanisms of the device is a fluorescent substrate of the light source that converts the original light into first converted light. Another wavelength-conversion mechanism of the device is a wavelength-conversion region optically coupled to the light source that converts the original light into second converted light. The original light, the first converted light and the second converted light are emitted from the device as components of the composite output light.
