Definitions

  • the combination of the array of LEDs and the light concentrating means may produce a predominantly parallel light beam, preferably divergent by less than about 2° or 3°, and said lens elements might be progressively different going outwardly for a generally concave array.
  • Such substantially wholly parallel light beam may simplify output lens requirements, as could first discussed position-focussing for substantially wholly forwardly directed light from such position, say a point or line.
  • Compound partly position focussed and partly otherwise directed light could facilitate use of existing output "glass" systems, i.e. as for tungsten lamp units.
  • Suitable geometries for the array of LEDs and the light concentrating means can have much less curvatures; indeed, be substantially flat in terms of substrate(s) or other carrier sheet(s) for the LEDs and for plural condensing lens elements, or as overall configuration of moulded multiple lens element means.
  • a substantially coplanar array of substantially identical plano-convex condensing lens elements will effectively have substantially coplanar foci in or near to which focal plane the array of LEDs can be positioned.
  • there is correspondence between sub-groups of the LEDs and individual condensing lens elements i.e. rather than one-one-one correspondence between LEDs and condensing lens elements (which is feasible but felt likely to be less advantageous than first preference for two or more LEDs per sub-group).
  • Engines and cabs will, of course, then need to be equipped with a light-sensitive sensing transducer and suitable demodulation means to produce drive signals for an audio loudspeaker (or head-phones) and/or a visual display, which provision can be of a quite simple and inexpensive nature.
  • Alternative fault detection etc strategies include normal first operation with part only of the totality of LEDs 212 lit up, say one of the groups 411 - 416 as a stand -by brought in after another of the groups 411 - 416, or other predetermined number of the LEDs 212, fails. Indeed, any possible LED positions not used in pursuit of multiples in and of groups/arms 411-416/421-426 could be used addit-ionally or alternatively for fault indication, say in said or another output "glass" part or addition for sideways or other viewing.

Claims (22)

  1. Signalleuchte für den Eisenbahnverkehr, die eine Vielzahl Licht aussendender Dioden (LEDs) (212; 312; 512) aufweist, die mehr als ausreichend dafür sind, eine Gesamtlichtabstrahlung zu erzeugen, die für den beabsichtigten Einsatz angemessen ist, wobei zumindest genug dieser LEDs gemeinsam mit Energie versorgt werden können, um diese ausreichende Lichtabstrahlung zu erreichen, wobei die Vielzahl von LEDs in einem flächigen Feld (211; 316X) in Verbindung mit ebenfalls flächig verteilten Einrichtungen zum Konzentrieren ausgesendeten Lichtes (116; 216; 316) eingesetzt wird und in Verbindung mit einer Vorrichtung für die Abgabe des gesamten Lichtausstoßes (225) wirksam ist, um ein Ausstoßlicht von vorherrschend im Wesentlichen paralleler Ausrichtung zu erzeugen, gekennzeichnet durch eine Gesamtausstoßlinse (225'), die eine neben dem Rand angeordnete Unterlinse (226; 326) für das seitliche Sehen des Lichtbetriebs aufweist.
