Abstract

The invention relates to light guiding slats having at least partially metallic-shining reflective upper sides for deflecting daylight and sun radiation. Light guiding slats are arranged horizontally and parallel with space relative to one another. The light guiding slats are disposed preferably outside, in front of, or within or behind glass façades and glass roofs. The invention is characterized by the upper sides of the light guiding slats which include at least partially line shaped indents 15 - 19. The line shaped indents 15 - 19 extend straight or diagonal, perpendicularly and/or inclined relative to the slat edges. The line shaped indents are designed to reflect light.
