Abstract: The present invention provides a light source having an improved output optical quality. In general, the light source comprises one or more light-emitting elements in each of at least a first, a second and a third colour. The combined spectral power distribution of these light-emitting elements generally defines a spectral concavity. The light source further comprises a light-excitable medium configured and disposed to absorb a portion of the light emitted by one or more of the light-emitting elements and emit light defined by a complementary spectral power distribution having a peak located within the concavity. By combining the spectral output of the light-emitting elements with the spectral output of the light-excitable medium, an optical quality of the light source is improved.

Abstract: The present invention provides a pulse-width modulation (PWM) method and apparatus, and light source driven thereby. In particular, the present invention provides a PWM method and apparatus for generating a PWM signal having a desired resolution and frequency using generating means traditionally limited to providing PWM signals having a lower resolution and/or frequency. The PWM method and apparatus of the present invention may be used in a number of applications where a relatively high PWM resolution and/or frequency is desired, but where selection of generating means for generating such PWM signals is relatively limited by cost and/or other such constraints. For example, a PWM signal generated by the method and apparatus of the present invention may be useful in accurately controlling the output of the one or more light-emitting elements of a light source, namely to control a dimming and/or colour level thereof, without using driving components that may be relatively costly for the application at hand.
