Abstract

This work deals with the maximum achievable output flux of LED-projectors which is limited by physics. With the objective of increasing the output flux further, the illumination unit of LED-based projectors is enhanced systematically by improving existing technologies and developing new concepts.

Abstract

"About projections" gives insights into world maps, their ways of representation and the associated worldviews. On the one hand, the projection is presented as an ideal projection in the sense of a worldview that describes prevailing mental images, values, order principles, ways of thinking or explanatory models of the world. On the other hand, the focus is on the geometric projection that underlies world maps: every world map faces the difficulty of displaying the spherical surface in a two-dimensional plane. In a reconstruction various paradigmatic worldviews are shown on the basis of world maps. In a deconstruction, conventional ones are contrasted by alternative world maps. The wide variety of possible world maps shows that world maps do not represent a status quo, but are merely a subjective interpretation of the world at a given time, which remain subject to constant upheavals.
