Abstract: The invention relates generally to illuminated signs (100) having multiple point light sources such as light emitting diode arrays as the illumination source for legend-bearing face panels and particularly to diffuser structure mountable in relation to such an array for facilitating an even distribution of light within such a sign to improve illumination of the typically translucent legend disposed on such a face panel. In particular, the invention employs a clear diffuser holder (120) that is secured to the inside surface of el the face panel thereby providing a means of removeably attaching a diffuser (130). The invention permits interchangeably employing diffusers of different colors while providing resistance to vandalism.
