Abstract

The method involves modulating the light from the light source so that the intensity impression on the human perception is maximized and the energy required to operate the light source is simultaneously minimized. The light modulation method can be electronic, optical, electro-optical, mechanical, mechano-optical, thermal, thermo-optical or quantum-optical. The light source can be a luminescent radiator, discharge lamp, semiconductor, thermal radiator or light arc.

Description

Stand der TechnikState of the art

Die Modulation von Lichtquellen zur Signalübertragung ist gängiges Verfahren in der Nachrichtentechnik. (U. Tietze Ch. Schenk: "Halbleiterschaltungstechnik", Springer Verlag Berlin Heidelberg 1993, Unger: "Optische Nachrichtentechnik" Hüthig Verlag)
Ziel moderner technischer Entwicklungen im Bereich von Lichtquellen ist die Energie­ einsparung, d. h. den Wirkungsgrad gegeben durch den Quotienten von abgegebener zur im Betrieb eingesetzten (aufgewendeten) Energie möglichst gleich 1 zu machen. (Hentschel: "Licht und Beleuchtung", Hüthig Verlag)
Der Helligkeitseindruck des Menschen von einer Lichtquelle ist - gemittelt über indivi­ duelle Unterschiede - abhängig von der Modulation der Lichtquelle (siehe beiliegende Briefe von Prof. Dr. Zrenner, Prof. Dr. L. T. Sharpe (beide Augenklinik Tübingen) in den Anlagen 1 und 2, sowie unveröffentlichte Messungen von A. Kamlage und Prof. Dr. H. Schmidt).The modulation of light sources for signal transmission is a common method in communications engineering. (U. Tietze Ch. Schenk: "semiconductor circuit technology", Springer Verlag Berlin Heidelberg 1993, Unger: "optical communications technology" Hüthig Verlag)
The aim of modern technical developments in the field of light sources is to save energy, ie to make the efficiency given by the quotient from the energy given to the energy used in operation as equal as possible 1. (Hentschel: "Light and Lighting", Hüthig Verlag)
The impression of brightness of a person from a light source - averaged over individual differences - depends on the modulation of the light source (see enclosed letters from Prof. Dr. Zrenner, Prof. Dr. LT Sharpe (both eye clinic Tübingen) in appendices 1 and 2, as well as unpublished measurements by A. Kamlage and Prof. Dr. H. Schmidt).
