Description

Anlage zur indirekten Beleuchtung von Innenräumen. Die Erfindung bezweckt, eine einfache und wirksame Anlage zur indirekten Beleuchtung von Innenräumen zu schaffen.System for indirect lighting of interiors. The invention aims a simple and effective system for indirect indoor lighting create.

An der Decke d ist ein kugeliger oder parabolischer Reflektor a mit der Öffnung nach unten befestigt, in seinem Brennpunkte b ist die Lichtquelle angeordnet und unterhalb derselben ein kugeliger, undurchsichtiger Spiegel c mit der der Lichtquelle zugekehrten äußeren Krümmung aufgehängt. Die Weite des Hilfsreflektors entspricht der Öffnungsweite des Deckenreflektors: Sein Radius und die Aufhängungshöhe sind so zu bemessen, daß alle parallel ankommenden Strahlen nach der zweckmäßig weiß gestrichenen Deckenfläche reflektiert werden. Der Metallzylinder f verhindert die Blendung durch direkte Strahlen, ohne die Bestrahlung des Hilfsreflektors zu beeinflussen.On the ceiling d is a spherical or parabolic reflector a the opening attached downwards, in its focal point b, the light source is arranged and below it a spherical, opaque mirror c with that of the light source facing external curvature suspended. The width of the auxiliary reflector corresponds to the opening width of the ceiling reflector: its radius and the height of the suspension are to be dimensioned in such a way that all rays arriving in parallel know according to the appropriate painted ceiling surface are reflected. The metal cylinder f prevents the Glare from direct rays without affecting the irradiation of the auxiliary reflector.
