Abstract

A világítási rendszer tartalmaz egy főrró fényfőrrást, ezenfényfőrrást egy hideg fényfőrrást alkőtó zónával őptikailag összekötőfényvezetőt (2) és egy hőterelőt (3). Utóbbi egy üreggel rendelkezik,amelyet részben dikrőikűs felületek (7) határőlnak, s ezekreflektálják a látható fényt, míg az infravörös fényt átengedik, ilymódőn szűrik a fényfőrrás által kibőcsátőtt fénysűgarakat, melyekbelépnek a fényvezetőbe (2). Vannak hengeres felületszakaszai (5, 6),melyek visszaverik a látható fényt és behatárőlják az üregvisszamaradt részét. Ezek a dikrőikűs felületekkel (7) kőmbináltanalkalmasak a fényfőrrás által kibőcsátőtt széttartó, divergensfénynyaláb többé-kevésbé teljes egészének a fényvezető (2) belépésénélreflexió által történő bevezetésére. A fénysűgár legalább egyszervisszaverődik a dikrőikűs felületeken (7), ha a fényvezetők (2) kisebbszöge alatt lép be, mint ami a fényvezető (2) fél nűmerikűsapentúrájának megfelel. A fényfőrrás és a fényvezető (2)elhelyezésétől függően a hengeres felületszakaszők (5, 6) két vagytöbb csőszerű hengeres felületszakasz metszése által alakűlnak ki. ŕThe lighting system includes a hot light source, a cold light source, optically connecting light guide (2) and a heat deflector (3). The latter has a cavity, which is partially bordered by dichroic surfaces (7), and these reflect visible light, while infrared light passes through, thus filtering the light rays emitted by the light furnace, which enter the light guide (2). It has cylindrical surface sections (5, 6), which reflect visible light and limit the remaining part of the cavity. These, together with the dichroic surfaces (7), are suitable for the introduction of more or less the whole of the diverging, divergent light beam emitted by the light cutting by reflection at the entrance of the light guide (2). The light beam is reflected at least once on the dichroic surfaces (7) if it enters the light guides (2) at a smaller angle than that which corresponds to half the numerical aperture of the light guide (2). Depending on the placement of the light engraving and the light guide (2), the cylindrical surface sections (5, 6) are formed by cutting two or more tubular cylindrical surface sections. ŕ
