1. An illumination system, comprising:

  • a straight rod having a first end, a second end, and peripheral surface extending longitudinally between the first end and the second end;

    a linear array of LEDs which emit light of a first wavelength;

    the linear array of LEDs positioned along the peripheral surface of the straight rod such that light of the first wavelength passes into the luminescent rod through the peripheral surface;

    the straight rod comprising a luminescent material which absorbs the light of the first wavelength and emits light of a second wavelength;

    a reflective element coupled to the first end of the straight rod to reflect light towards the second end of the straight rod; and

    the second end of the straight rod forming an outlet aperture for emitting light from the straight rod;

    whereby the straight rod generates light of the second wavelength in response to excitation by light of the first wavelength and emits light of the second wavelength through the outlet aperture.
