Definitions

  • the present invention relates to lighting systems, and in particular to such systems as used for the definition of vehicle pathways such as aircraft runways and roads. 5
  • One of the methods currently in use by traffic planners in their efforts to overcome traffic congestion is a "tidal flow system".
  • multi-lane roads have the direction of traffic flow in one or more lanes changed according to the direction of main traffic flow.
  • a major problem with this method is defini ⁇ te" tion of direction of flow in the particular lane.
  • One means for defining the flow is the use of signals on gantries, but these tend to distract a driver's attention from the road ahead, and can be missed.
  • lanes be designated by a series of 15 lights in the road surface, the lights being illuminated either red or green.
  • Light installations suitable for this purpose are already in use in airfield runway and perimeter track layouts. These light installations have to be extremely robust to withstand vehicle impact, and also have to be constructed to allow access for the 20 change of light bulbs.
  • a major drawback with this type of system for road use rises from the life of the light bulbs, which is typically of the order of 500 hrs. This means that sections of road will have to be periodically closed to allow bulbs to be replaced, and this will inevitably result in local traffic congestion of the 25 type which the planners are aiming to avoid.
  • One method of over ⁇ coming this problem is to provide the illumination by means of optical fibres leading from light sources situated at the side of a road.
  • an illuminated device includes at least one optical display unit and at least one light unit situated remotely from the optical display unit, the or each light unit being connected to at least one display unit by means of a fibre optic cable whereby light is conveyed from each light unit to at least one optical display unit, and means for conveying heat from each light unit to at least one optical display unit.
  • Heat may be generated in the light unit by an infra red light generator, and this heat can be conducted through the same fibre optic cable as the visible light.
  • the materials from which fibre optic cables are made differ in the efficiency with which they transmit light in different wavelengths. It will therefore usually be preferable to use a separate fibre optic cable for the conduction of heat in the form of infra-read light.
  • a material such as "Red Vycor", as manufactured by Corning, might be suitable for the conduction of heat.
  • An alternative source of heat is the visible light generator itself.
  • the light unit is advantageously small and sealed and the heat generated therein is likely to result in a requirement for cooling of the unit.
  • cooling is a problem.
  • Another form of the invention therefore, includes means for transferring warm air from the light unit to the display unit.
  • air is then transferred back from the display unit to the light unit, forming a closed system with minimal requirement for drying of the air.
  • air can be allowed to exhaust from the display unit, but in such a case fresh air must be supplied to the light unit and this air must be filtered and dried.
  • Air can be transferred by pipes of, for example, plastics material and the light unit may include means, such as a fan, to provide a pressure differential. There might also be provision in a closed air system for air to be exhausted from the display, unit and fresh air admitted to the light unit in very warm conditions.
  • a typical fibre optic cable as used in the invention may be single stranded at the light unit end and multi-b anched at the display unit end.
  • Each visible light unit may be equipped with a series of filters, preferably remotely controlled, by which the colour of the light displayed by any associated display unit can be adjusted as required.
  • the infra-red light generators or air delivery systems are preferably controlled independently from the visible light unit by, for example, moisture detectors, temperature sensing devices or both.
  • a vehicle pathway defini ⁇ tion system includes a series of optical display units embedded in a surface of the pathway, and a series of light units situated re ⁇ motely from the optical display units, each light unit being con ⁇ nected to at least one display unit by means of a fibre optic cable, whereby light is conveyed from the light units to the optical display units, and means for conveying heat from the light units to the display units.
  • Figure 1 is a plan view of part of a three lane road
  • Figure 2 is an elevation, in section, along line 2-2 of Figure
  • Figure 3 is an elevation, in section, of a- detail of Figure 2.
  • Figure 4 is an elevation, in section, of an alternative form of light unit.
  • a road 10 (Figure 1) has three lanes 11, 12, 13 defined between kerbs 14 and 15 and rows 16, 17 of display units such as those shown at 18.
  • Each display unit 18 has an associated light unit 19 situ- 5 ated at some distance from the road 10.
  • Each display unit 18 (see Figure 2) is joined to an associated light unit 19 by means of a fibre optic cable 20.
  • Each light unit 19 lies in a hole 21 in a pavement 22 adjacent to the road and access thereto is by means of an access cover 23-
  • 1Q 19 ( Figure 3) contains a visible light unit in the form of a bulb 24 from which light is passed via a prism 30 to the fibre optic cable 20, and an infra-red light generator in the form of a bulb 31 by means of which infra-red light passes via a prism 32 to the fibre optic cable 20.
  • Each light unit also contains (not shown in Figure
  • the light unit 19 also contains a remotely operated switching unit 33 for control of the infra-red bulb 3 • Operation of the remotely controlled switch 33 is prefer ⁇ ably by means of a moisture detector, a thermostat, or both.
  • the display units 18 are illuminated to define vehicle flow paths using the visible light bulbs 24 only.
  • adverse weather conditions such as, for example, rain or frost sensors such as the moisture detector and thermostat operate to actuate the switch 33 to switch on the infra-red bulb 3 -
  • the infra-red bulbs 31 can be controlled independantly of the visible light bulbs 24. In this way when display systems are in non-continuous use the display units 18 can be cleared of misting or frost in adverse weather conditions prior to their being used for the display of visible light.
  • a typical use of a display system -__- such as that described about is in a "tidal flow system".
  • two lanes 12, 13 are made available to traffic flowing in this direction.
  • Light Units 19 are activated so that each visible light bulb 24 is illuminated and has a red filter
  • the display units 18 or the row 16 are thereby illuminated red and drivers approaching will know that they are not allowed to cross this line.
  • the other row 17 of display units 18 can be left un-illuminated, or alternatively can be ill ⁇ uminated green.
  • the infra-red light bulb 31 can be left switched off, to be switched on only when damp or icy conditions are present or expected.
  • each light unit 19 contains a visible light bulb 24 from which light is fo ⁇ - ussed by a mirror 50 and lens 51 onto a fibre optic cable 20.
  • Air circulation is effected by a fan 54.
  • Air might be allowed, for example, to vent from the optical display unit whilst fresh air, after filtering and drying, is admitted to the light unit 19.
  • the invention has been described as used for vehicle pathways such as roads it could usefully be used in some instances for vertical display units such as road signs and advertisement ' s. However the latter are not so ' prone to misting and icing, due to their vertical disposition, and also are in general easier of access to allow conventional heating elements to be installed, and where necessary replaced, adjacent to display units 18.

Abstract

Un système, par exemple pour définir ou réguler des voies pour le passage de véhicules, dans lequel la lumière est transférée par des câbles en fibres optiques (20) depuis des unités (19) génératrices de lumière visible situées à distance jusqu'à des unités d'affichage montées sur la surface de la chaussée ou de la piste, comprend des moyens pour transférer aux unités d'affichage la chaleur provenant des unités de lumière (19). La chaleur peut être produite par des générateurs de lumière infrarouge (31) et acheminée jusqu'à l'unité d'affichage par le même câble en fibres optiques (20) qui y transfert la lumière visible, ou bien par un câble en fibres optiques séparé. Dans une variante, la chaleur produite par les moyens générateurs (24) de lumière visible peut être acheminée par un tuyau, sous forme d'air chauffé, jusqu'à l'unité d'affichage, où ledit air peut être déchargé ou renvoyé à l'unité de lumière (19).
