ABSTRACT:
An illumination system, useful for generating illumination light in an image-projection system, has at least a first image-forming panel. A first array of light emitting elements, for example light emitting diodes (LEDs), generates a first light beam associated with a first wavelength range. A second array of light emitting elements generates a second light beam associated with a second wavelength range. The second array of light emitting elements comprises at least a first light emitting element generating light in the second wavelength range and a second light emitting element generating light in the first wavelength range. The center wavelength of the second light emitting element may be closer in value to the center wavelength of a light emitting element in the first array than to the center wavelength of the first light emitting element.
