Abstract
Disclosed is an exemplary illumination device for enhancing the brightness and chromaticity of an illuminator employing light emitting diodes (LED). The illumination device may include a first light source configured to emit light at a first wavelength range. A first dichroic optical element associated with the first light source may be configured to optically block less than the entire wavelength range of the light emitted from the first light source. The illumination device may also include a second light source configured to emit light at second wavelength range substantially corresponding to the wavelength range optically blocked by the first dichroic optical element.
