Abstract:
A light emitting diode module is produced using at least one light emitting diode (LED) and at least two selectable components that form or are part of a light mixing chamber that surrounds the LEDs and includes an output port. A first selectable component has a first type of wavelength converting material with a first wavelength converting characteristic and a second selectable component has a second type of wavelength converting material with a different wavelength converting characteristic. The first and second wavelength converting characteristics alter the spectral power distribution of the light produced by the LED to produce light through the output port that has a color point that is a predetermined tolerance from a predetermined color point. Moreover, a set of LED modules may be produced such that each LED module has the same color point within a predetermined tolerance. The LED module may be produced by pre-measuring the wavelength converting characteristics of the different components selecting components with wavelength converting characteristics that convert the spectral power distribution of the LED to a color point that is a predetermined tolerance from a predetermined color point.
