A light emitting diode (LED) illumination apparatus comprises a hollow and perforated shield in which a plurality of apertures are formed throughout the periphery and length thereof; a plurality of linear arrays of LED elements housed within the shield and arranged such that light generated by the LED elements is emitted through the apertures to produce a plurality of longitudinally and peripherally spaced colored spots; and a diffusing element attached to, or in juxtaposition with, the inner surface of, and of a similar cross section as, the shield to ensure that all of the plurality of spots are illuminated at a substantially uniform light intensity. |
