  2. Window covering - Wikipedia

    en.wikipedia.org/wiki/Window_covering

    The height of the blind and the angle of the slat can be determined by daylighting demand and solar positions (azimuth, altitude). By controlling the height of shades or blinds, the optimal amount of sunlight can be introduced to meet the target horizontal illuminance (work plane illuminance). The optimal angle of the blind slats can protect ...

    With no applied voltage, the micro-blinds are rolled and let light pass through. When there is a potential difference between the rolled metal layer and the transparent conductive layer, the electric field formed between the two electrodes causes the rolled micro-blinds to stretch out and thus block light.

  4. Solar-blind technology - Wikipedia

    en.wikipedia.org/wiki/Solar-blind_technology

    Solar-blind technology is a set of technologies to produce images without interference from the Sun. This is done by using wavelengths of ultraviolet light that are totally absorbed by the ozone layer, yet are transmitted in the Earth's atmosphere. Wavelengths from 240 to 280 nm are completely absorbed by the ozone layer.

  5. Window blind - Wikipedia

    en.wikipedia.org/wiki/Window_blind

    Various window blind styles. A window blind is a type of window covering. [1] There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats.

  6. Nonimaging optics - Wikipedia

    en.wikipedia.org/wiki/Nonimaging_optics

    Nonimaging optics (also called anidolic optics) [1] [2] [3] is a branch of optics that is concerned with the optimal transfer of light radiation between a source and a target. . Unlike traditional imaging optics, the techniques involved do not attempt to form an image of the source; instead an optimized optical system for optimal radiative transfer from a source to a target is desi

  7. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
