摘要： This invention relates to a color controlled light source comprising a plurality of colored light elements; a detector for detecting the light output of the light source and generating a detection signal; and a color control unit for generating driving signals to said light elements on the basis of said detection signal and a predetermined target color point of the light output of the light source. In order to enable detection of contributions from individual light elements to the light output of the light source, the light source further comprises a modulator for individual signature modulation of the driving signal to each one of said light elements; and a corresponding demodulator for demodulation of said detection signal and generation of actual, i.e. measured, values of the output of the individual light elements. The color control unit determines nominal values of the light output of each light element for obtaining said target color point, and compares the actual values with the nominal values. If there is a difference, it adjusts the driving signals in order to minimize the difference.

摘要： Disclosed is a light module package including a mounting substrate for mounting and electrically contacting at least one light emitting diode and a ceramic layer disposed in a path of light emitted by the light emitting diode. The ceramic layer includes a wavelength converting material and the light emitting diode is disposed between the ceramic layer and the mounting substrate. The light module package also includes a light sensor disposed at the mounting substrate for detecting a luminous output of the light emitting diode in order to control the brightness and/or the color of the light leaving the light module. The ceramic layer is only partly translucent to shield the light sensor against ambient light.

摘要： The invention relates to a method and a system for translating a three value color space signal, preferably given in a CIE scale, to an n primary color space signal, where n is an integer greater than or equal to 4, thus providing color controlling of a white light source comprising an array of colored light emitting diodes with respect to maximum CRI and maximum luminous efficiency.
