Definitions
- the present invention relates to light beacon installations and in particular surface light beacon installations for aeronautics.
- the lighting installations must guarantee visibility of the signaled area, at a distance as large as possible, and this, in all directions.
- a lighting installation must minimize the risk of dazzling the pilot in the final phase of the landing.
- Known lighting systems are distinguished in particular by the type of light sources used. These light sources generally fall into two categories, on the one hand, incandescent and halogen bulbs and, on the other hand, ionization tubes. The latter notably include discharge tubes (mercury or sodium vapor, low or high pressure), and rare gas tubes.
- discharge tubes or sodium vapor, low or high pressure
- rare gas tubes In known installations, whatever the light source used, it must be accompanied by an optic intended to distribute and direct the light flux. The main purpose of this optic is, on the one hand, to guarantee visibility from all angles of view which may arise during location and approach and, on the other hand, to sufficiently diffuse the light beam in order to eliminate any risk of dazzling the pilot.
- a first drawback of the installations of the prior art is the need to use optics, often bulky, to give the light beam an adequate geometry. Indeed, most of the time, the size of the optics prohibits the use of surface beaconing or, in other words, the use of light sources placed under the landing area and emitting their light beams through a surface transparent formed in the floor covering.
- An object of the present invention is therefore to remedy the drawbacks of the above-mentioned prior art by providing a lighting installation in accordance with claim 1.
- a first advantage of the present invention is therefore that it does not require an optical system to diffuse the light produced by a single light source.
- a second advantage of the present invention is that the diodes are light sources of significantly smaller sizes compared to the light sources used in the prior art.
- the lighting installation in accordance with the present invention does not require optics intended to shape the light beam, it is possible to produce extremely flat installations capable of being embedded in the floor covering of the area. landing.
- a third advantage of the present invention is that the low unit cost of the diodes, combined with their small size, makes it possible to implement a high number of them simultaneously. Thus, the possible failure of a diode will have no appreciable effect on the visibility of the markup.
- a fourth advantage of the present invention is that the diodes have a lifespan considerably greater than most of the light sources used in the prior art.
- the light emitting diodes resist temperature variations in a range from around -40 C to +85 C.
- a fifth advantage of the present invention is that the individual diodes give off little heat during their operation. It is therefore normally not necessary to provide cooling means for the installation of lighting systems according to the present invention.
- - Figure 1A is a block diagram of the arrangement of several light emitting diodes according to different inclinations to allow good visibility whatever the height of the aircraft above the horizon;
- - Figure 1B shows the assembly of 94 light-emitting diodes on a horizontal support;
- Figure 2 shows an assembly of several horizontal supports, similar to that of Figure 1B, oriented in different directions so as to allow substantially uniform visibility in all directions and all elevations;
- FIG. 3 shows a heliport equipped with a lighting installation according to the present invention
- FIG. 4 is the diagram of the electronic circuit supplying the 94 diodes shown in Figure 1B;
- FIG. 5 is a diagram of the regulated supply circuit intended to supply the circuit of FIG. 4.
- Figure 1 A is a block diagram of the arrangement of several light emitting diodes 1a, 1b and 1c according to different inclinations to produce a visible light beam regardless of the elevation ⁇ of the observer above the horizon. It can be seen in FIG. 1A that the diode 1b inclined at 45 degrees is placed in front of the diode 1c inclined at 80 degrees and that the diode 1a inclined at 30 degrees is placed in front of the diode 1b. This arrangement has the advantage of avoiding one diode masking another.
- Figure 1B shows an example of assembling 94 diodes 1a, 1b and 1c on a horizontal support 2.
- the 94 diodes 1 form three groups 1a, 1b and 1c whose light beams make angles of 30 respectively , 45 and 80 degrees from the horizontal.
- 42 diodes make an angle of 30 degrees relative to the horizontal
- 42 make an angle of 45 degrees
- 10 make an angle of 80 degrees.
- the light-emitting diodes available on the market are distinguished in particular by the particular angular opening of the light beam which they emit.
- the block diagram of FIG. 1A does not concern so that a particular type of these diodes.
- a person skilled in the art will know how to choose inclinations adapted to the particular shape of the light beam produced by these diodes in order to obtain a light beam appropriately distributed in space.
- FIG. 2 shows an assembly 5 of eight horizontal supports 2.
- the orientation of the horizontal supports, or sectors presents a rotation symmetry of order 8.
- two neighboring sectors 2 make between them a horizontal angle of 45 degrees. This arrangement guarantees good visibility in all directions.
- the rosette-shaped assembly 5, shown in FIG. 2 only takes up a small amount of space. Indeed, the diameter of the rosette 5 grouping together in this example 752 diodes could typically be 19 cm.
- the assemblies 5, or rosettes are still arranged side by side in groups of five. These groups 7 are mounted in robust and waterproof boxes, the upper face of which is transparent. The length of the box housing in this example five rosettes 5, and therefore 3760 diodes, is approximately 1 meter. Its width is approximately 20 cm and its height 5 cm.
- FIG. 3 represents a heliport equipped with a lighting installation according to the present invention.
- the lighting installation in FIG. 3 comprises sixteen groups 7 (referenced 7a to 7p) of five rosettes 5 each. It can also be seen in FIG. 3 that each group 7a, ..., 7p is connected to a power supply line generally referenced 9. All of the supply lines 9 are connected to supply and supply means. control not shown in Figure 3.
- the beaconing installation shown in FIG. 3 is a ground installation. Under these conditions, it is advantageous to embed each of the boxes containing a group 7 of five rosettes in the floor covering. As the boxes are only about 5 cm high, they can be installed in the covering without excessive cost. In addition, this provision prevents groups 7 from constituting obstacles near the area. landing. Thus, the safety of use of the landing zone is increased.
- the lighting installations must obey certain constraints as for the color of the emitted light. This additional constraint stems from legal or regulatory requirements.
- the colors usually required are green, red and white.
- the choice of diodes available on the market makes it possible to produce lighting installations according to the present invention which obey the above-mentioned prescriptions.
- FIG. 4 is the diagram of the electronic circuit ensuring the supply of the 94 diodes represented in FIG. 1 B.
- the circuit represented in FIG. 4 comprises first of all seven groups (referenced 11 to 17) of diodes 1 connected in series. As can be seen in the figure, groups 11 and 12 each have 16 diodes, groups 13, 14 and 17 have 14, and finally, groups 15 and 16 each have 10.
- Groups 11 to 17 are supplied in parallel. As can also be seen in FIG. 4, resistors (referenced 21 to 27) are still connected in series with each of the groups of diodes 11 to 17. The value of each of these resistors is chosen so that the current flowing in the different diodes is the same.
- the circuit of FIG. 4 also comprises a bridge rectifier 18 transforming into direct current, the alternating current supplied by a regulated supply circuit (not shown in FIG. 4).
- a regulated supply circuit not shown in FIG. 4
- the supply voltage supplied at the output of the rectifier 18 can be adjusted between a few volts and a maximum of 48 volts.
- each individual diode will be subjected to a maximum voltage of approximately 3 volts.
- the bridge rectifier 18 also supplies seven other assemblies each comprising 94 diodes.
- a single rectifier 18 is able to supply the 752 diodes that comprise a rosette 5 (FIG. 2).
- FIG. 5 is a diagram of the regulated supply circuit intended to supply the bridge rectifier 18.
- the circuit of FIG. 5 comprises two input lines referenced 28, 29 and two output lines 30 and 31.
- the lines of input and output lines are connected by a step-down transformer referenced 33.
- the input lines 28 and 29 can be directly connected to the three-phase network.
- Line 28 will be connected to neutral, while line 29 will be connected to one of the three phases.
- Thyristors referenced 35 and 36 are provided to regulate the power supplied to the transformer 33.
- the thyristors 35, 36 are themselves controlled by a programmable control circuit (not shown) supplying a control current by the lines 37, 38, 39 and 40. Thanks to the assembly which has just been described, the programmable control circuit can vary the voltage supplied to the groups of diodes 11 to 17 (FIG. 4) between a few volts and a maximum of 48 volts.
- the electrical diagram of FIG. 5 also includes a voltage control circuit and a current control circuit respectively referenced 42 and 43. These circuits are connected to the output lines 30 and 31.
- the voltage control circuit 42 comprises a rectifier in bridge 44. This circuit is designed to supply the programmable control means (not shown) with a signal representative of the alternating voltage between the two output lines 30 and 31.
- the current control circuit 43 includes a transducer 45. This circuit is provided to supply the programmable control means with a signal representative of the current flowing on the output lines 30 and 31.
- the control circuits 42 and 43 make it possible in particular to detect any change in the electrical resistance of the circuits supplied by the bridge rectifier 18.
- the current control means 43 detect a slight drop in the current flowing in the output lines 30 and 31 supplying the diodes.
- Control means Programmables react to this drop in current by producing a signal intended to indicate to the person in charge of maintenance that a diode must be changed.
- the foregoing description relates only to a very particular embodiment of the present invention. From the present text, a person skilled in the art will be able to carry out many other forms of the present invention. It may be noted, in particular, that the programmable control means can be replaced or supplemented by manual control. On the other hand, the electronic circuits used to supply the diodes can be of various shapes and can, moreover, be installed both in the immediate vicinity of each group of diodes and remotely, with the control means by example.
