Automatic control regulating incidence of light in living or work-place room - uses stack of similar profiled deflectors having three reflective concave surfaces

Several opaque elements (2,3) are aligned between outer (300) and inner (301) vertical straight imaginary lines in parallel. Their relative positions are fixed. At least their top sides (21, 31) have at least one concave reflective section, while their lower sides have at least two reflective parts...

Beschreibung
Zusammenfassung:	Several opaque elements (2,3) are aligned between outer (300) and inner (301) vertical straight imaginary lines in parallel. Their relative positions are fixed. At least their top sides (21, 31) have at least one concave reflective section, while their lower sides have at least two reflective parts (22,32;33,60). The joining part (18,30) of the latter faces the upper surface of the opaque profiled element installed below it. The space between the inner and outer aligning lines (300,301) does not exceed 10 mm. The angle of inclination (alpha) of a straight line (305) to a vertical (304) extending through both limiting lines (300, 301) is set be the equation alpha equals f(beta)+(15 deg.-x), where f(beta) is a function dependent on the angle of inclination, beta, of the vertical (304) to the ground surface, and x is a selectable angle. USE/ADVANTAGE - Diffused light suitable for working with VDU's without wastage of available daylight of artificial light applied to the deflectors.
