An illumination device projects light in a predetermined illumination pattern on a surface. The illumination device includes a housing having a cavity and an aperture. The illumination device includes a light module for selectively emitting the light and a screen at least partially disposed in the cavity between the light module and the aperture. The screen has at least one opening defining a base pattern configuration corresponding to the predetermined illumination pattern for aligning the light through the opening into the base pattern configuration and subsequently projecting the light through the aperture onto the surface in the predetermined illumination pattern. The illumination device includes a condensing lens disposed between the light module and the screen for collimating the light toward the screen and an objective lens arrangement disposed between the screen and the aperture for transforming the light from the base pattern configuration into the predetermined illumination pattern.
