Field of application
[0001] The present finding refers to a light indicator, according to the preamble of independent claim 1.
[0002] The present light indicator is inserted in the industrial field of production of light indicators and illumination devices provided with light sources, in particular of LED type, and is intended to be advantageously employed for making a landing platform or runway more easily visible to aircraft vehicles, such as helicopters.
[0003] In addition, the aforesaid light indicator is advantageously employed for signaling to the pilot of an aircraft vehicle the possibility or impossibility of executing the landing on the landing platform or runway on which the light indicator itself is installed.
Field of the art
[0004] It is known to use light indicators mounted on landing platforms, in particular for example heliports installed on marine facilities for extracting oil or ships, in order to make the landing platform itself more easily visible by aircraft pilots.
[0005] Such light indicators are also employed for signaling the possibility or impossibility for an aircraft vehicle to land, and such impossibility can for example be due to adverse atmospheric conditions, to the presence of inflammable or explosive gases near the same landing platform (in particular in the event in which the landing platform is installed on an oil extraction facility) or to the presence of another aircraft vehicle that occupies the platform.
[0006] The light indicators of known type generally comprise a containment casing formed by a base body, in particular metallic, and by a transparent cap fixed to the base body and delimiting a housing volume therewith, within which light sources are placed which are arranged for emitting light beams which show the landing platform or runway on which the light indicator itself is installed.
[0007] In particular, such light sources are of LED type, since they demonstrate greater light efficiency with respect to most of the light sources of conventional type (such as for example incandescent lamps, fluorescent lamps, discharge lamps).
[0008] More in detail, in addition, the aforesaid light indicators are provided with a support tube placed inside the housing volume and carrying, mounted thereon, the LED light sources, which are arranged for emitting light beams to traverse the transparent cap.
[0009] In particular, the support tube is extended along an extension direction thereof that is substantially vertical between a base portion fixed to the base body of the containment casing and an opposite top portion and carries, mounted thereon, first LED light sources on a lateral surface thereof, which is extended around the extension direction, in a manner such that the light indicator can emit the light beams along directions transverse to the extension direction itself, and second LED light sources on the top portion, in a manner such that the light indicator can emit light beams substantially vertically along the extension direction.
[0010] The light indicators of known type described briefly up to now has in practice shown that it does not lack drawbacks.
[0011] The main drawback of the light indicators of known type lies in the fact that the support tube is attained by means of a metal extrusion working, which is simple and inexpensive to execute but confers to the support tube itself a substantially prismatic shape. Therefore, the lateral surface of the support tube comprises multiple lateral faces extended parallel to the extension direction and therefore intended to be placed vertical once the light indicator is installed on the landing platform or runway. Consequently, the first LED light sources are provided with printed circuit boards fixed to the lateral faces and carrying, mounted thereon, multiple LEDs with their optical emission axis substantially perpendicular to the same lateral faces and, thus, horizontal. However, the light beams emitted by the first LED light sources must be at least partially tilted upward, in a manner such that they can be seen by the pilot of an aircraft vehicle. Therefore, the first LED light sources must be provided with deflection lenses mounted on the printed circuit boards at the corresponding LED thereof and adapted to deflect the light beams from the horizontal direction towards directions tilted upward and to collimate them along the aforesaid tilted directions. Such deflection lenses, however, reduce the brightness of the same light beams and hence the overall efficiency of the LED light sources.
Presentation of the finding
[0012] In this situation, the problem underlying the present finding is therefore that of eliminating the problems of the abovementioned prior art, by providing a light indicator, which is capable of operating in an entirely efficient manner.
[0013] A further object of the present finding is to provide a light indicator, the light sources of which do not have to be provided with deflection lenses.
[0014] Further object of the present finding is to provide a light indicator which is structurally simple and inexpensive to attain.
[0015] A further object of the present finding is to provide a light indicator, which is entirely reliable in operation.

Detailed description of a preferred embodiment
[0017] With reference to the enclosed drawings, reference number 1 overall indicates the light indicator, object of the present finding.
[0018] The present light indicator 1 is intended to be advantageously mounted on landing platforms or runways, in particular heliports installed on marine facilities for extracting oil or ships, in order to render the landing platform or runway itself more easily visible by an aircraft vehicle, e.g. a helicopter.
[0019] The light indicator 1 according to the present finding comprises at least one containment casing 2 provided with a base body 3 and with a closure body 4, which is fixed to the base body 3, delimits a housing volume therewith and is provided with at least one transparent portion 5 susceptible of being traversed by the light.
[0020] With the expression "transparent portion" it must be intended hereinbelow a portion of the closure body 4 susceptible of being traversed by the electromagnetic radiation in the visible spectrum or in at least part of the visible spectrum.
[0021] In addition, the present light indicator 1 comprises at least one support body 6, which is placed inside the housing volume of the containment casing 2, is extended along an extension direction X that is substantially vertical between a base portion 7 and an opposite top portion 8 and is provided with a lateral surface 9 extended around the extension direction X between the base portion 7 and the top portion 8.
[0022] The present light indicator 1 also comprises multiple first light sources 10 mounted on the lateral surface 9 of the support body 6, placed around the extension direction X and each provided with a first optical emission axis Y thereof which intercepts the transparent portion 5 of the closure body 4.
[0023] In order to ensure a high light efficiency for the present light indicator 1, the first light sources 10 are advantageously of LED type.
[0024] Advantageously, the transparent portion 5 of the closure body 4 has substantially cap shape, in a manner such to be extended adjacent to the lateral surface 9 of the support body 6, on which the first light sources 10 are placed, and above the top portion 8.
[0025] Preferably, the support body 3 of the containment casing 2 comprises a bottom wall 38 and a coupling rib 39, which is extended perimetrically protruding from the aforesaid bottom wall 38, and the closure body 3 comprises a coupling ring nut 40, which carries the transparent portion 5 mounted thereon, in particular having cap shape, and is fixed to the coupling rib 39 of the support body 3 in order to close the housing volume.
[0026] In particular, the base portion 7 of the support body 6 is fixed to the support body 3, in a manner such that the support body 6 remains in position within the housing volume.
[0027] According to the idea underlying the present finding, the support body 6 is extended, at least partially along the extension direction X, with shape tapered from the base portion 7 towards the top portion 8, and the lateral surface 9 is tilted with respect to the extension direction X and supports the first light sources 10 with the first optical emission axis Y oriented partially upward.
[0028] In this manner, the first light sources 10 do not have to be provided with suitable deflection lenses in order to direct the light beams, deflecting them from the horizontal direction upward, since the same first light sources 10 are already partially directed upward, being mounted on the tilted lateral surface 9 of the tapered support body 6 from the base portion 7 towards the top portion 8.
[0029] Advantageously, the lateral surface 9 is tilted with respect to the extension direction X by a tilt angle α substantially comprised between 10° and 20°.
[0030] In addition, the first optical emission axis Y of each first light source 10 is substantially orthogonal to the lateral surface 9 of the support body 6.
[0031] In this manner, the first optical emission axis Y of each first light source 10 preferably forms, with the extension direction X of the support body 6, an orientation angle β, directed upward, substantially comprised between 70° and 80°.
[0032] Advantageously, the lateral surface 9 of the support body 6 is provided with multiple lateral faces 11, substantially flat, placed one next to the other around the extension direction X, and on such lateral faces 11 the first light sources 10 are mounted.
[0033] For example, the support body 6 can have substantially frustoconical shape and be provided with lateral faces 11 having substantially trapezoid shape and in turn tapered from the base portion 7 towards the top portion 8.
[0034] In particular, the first optical emission axis Y of each first light source 10 is substantially orthogonal to the corresponding lateral face 11.
[0035] The support body 6 is advantageously provided with at least eight lateral faces 11, preferably ten and still more preferably twelve, as illustrated for example in the enclosed figure 4.
[0036] More in detail, with the increase of the number of lateral faces 11 on which the first light sources 10 are mounted, the uniformity increases of the intensity of the light beams emitted by all the first light sources 10 circumferentially around the extension direction X. In particular, the arrangement of twelve lateral faces 11 on the lateral surface 9 of the support body 6 ensures a high level of uniformity of the intensity of the light beams emitted by the first light sources 10 around the extension direction X.
[0037] Advantageously, the support body 6 comprises a base support 12, which is placed at the base portion 7 and is provided with a first perimeter edge 13 extended around the extension axis X, and a top support 14, which is placed at the top portion 8 and is provided with a second perimeter edge 15 extended around the extension axis X.
[0038] The support body 6 also advantageously comprises multiple lateral walls 16, which are placed around the extension direction X, are fixed to the first perimeter edge 13 of the base support 12 and to the second perimeter edge 15 of the top support 14 and define the lateral surface 9 of the support body 6.
[0039] More in detail, the lateral faces 11 are each extended on a corresponding lateral wall 16 of the support body 6.
[0040] In particular, the base support 12 and the top support 14 have substantially plate-like extension and are placed parallel to each other.
[0041] The first perimeter edge 13 and the second perimeter edge 15 preferably both have polygonal shape, e.g. dodecagon, and are provided with a same number of sides, in a manner such that each lateral wall 16 is fixed, on one side, to one side of the first perimeter edge 13 of the base support 12 and, on the other side, to a corresponding side of the second perimeter edge 15 of the top support 14.
[0042] Advantageously, the first perimeter edge 13 of the base support 12 has width, transverse to the extension direction X, greater than the second perimeter edge 15 of the top support 14.
[0043] In addition, advantageously, the lateral walls 16 are mechanically fixed to the base support 12 and to the top support 14 by means of fixing screws 17.
[0044] Advantageously, the base support 12 and/or the top support 14 and/or the lateral walls 16 are made of thermally conductive material, preferably metallic, such as for example aluminum or an alloy thereof.
[0045] Preferably, the base support 12, the top support 14 and the lateral walls 16 are all made of metal material, in a manner such to facilitate the transfer of heat from the first light sources 10 of LED type, which tend to be considerably heated during operation, to the support body 16.
[0046] In addition, the lateral walls 16 advantageously delimit between them, at least partially at their interior, a hollow volume.
[0047] In this manner, at least the lateral walls 16, which are preferably made of metal material, can easily transfer the heat produced by the first light sources 10 of LED type to the air within the hollow volume.
[0048] In order to facilitate the passage of the air entering and exiting from the hollow volume defined between the lateral walls 16, the base support 12 is advantageously provided with at least one first opening 18 communicating with the hollow volume and the top support 14 is advantageously provided with at least one second opening 19 communicating with the hollow volume.

[0050] In particular, the first opening 18 and the second opening 19 have substantially circular shape and are placed concentric with respect to the extension direction X.
[0051] In addition, the first opening 18 preferably has width (or diameter in the event in which the first opening 18 has substantially circular shape), transverse to the extension direction X, at least equal to or greater than half of the width of the first perimeter edge 13 of the base support 12.
[0052] Analogous to the first opening 18, the second opening 19 preferably has width (or diameter in the event in which the second opening 19 has substantially circular shape), transverse to the extension direction X, at least equal to or greater than half of the width of the second perimeter edge 15 of the top support 13.

[0054] In addition, the base support 12 is advantageously placed spaced from the bottom wall 38 of the base body 3, defining a second interspace communicating with the hollow volume by means of the first opening 18 of the base support 12.
[0055] In this manner, the second interspace allows the passage of air within the hollow volume defined between the lateral walls 16 from below, even if the support body 6 is fixed to the base body 3 at the base portion 7.
[0056] Advantageously, the support body 6 comprises one or more second spacer elements 44, each of which extended along a second main direction thereof between a fifth end fixed to the bottom wall 38 of the base body 3 and an opposite sixth end fixed to the base support 12.

[0058] In particular, each fixing body 20 has substantially rod-like extension and is extended inside the hollow volume between a first end fixed to the base support 12 and an opposite second end fixed to the top support 14.
[0059] In addition, each fixing body 20 is preferably extended between the first end and the second end along an extension axis thereof substantially parallel to the extension direction X of the support body 6.
[0060] More in detail, the first and the second end of each fixing body 20 is respectively fixed to the base support 12 and to the top support 14 by means of retention screws 43.
[0061] In this manner, in order to assemble the support body 6, first, it is sufficient to rigidly fix together the base support 12 and the top support 14 by mechanically connecting the first end of each fixing body 20 to the base support 12 and the second end of each fixing body 20 to the top support 14 by means of the retention screws 43, and subsequently, it is sufficient to fix each lateral wall 16 to the first perimeter edge 13 of the base support 12 and to the second perimeter edge 15 of the base support 14 by means of the fixing screws 17.
[0062] Advantageously, the first light sources 10 are organized in multiple optical modules 21 mounted on the lateral surface 9 of the support body 6.
[0063] More in detail, each optical module 21 is mounted on a corresponding lateral face 11 of the lateral surface 9, i.e. in particular each optical module 21 is mounted on a lateral wall 16 of the support body 6.
[0064] Advantageously, each optical module 21 comprises at least one first printed circuit board 22, each of which fixed to the lateral surface 9 of the support body 6, and in particular to a corresponding lateral face 11 of the lateral surface 9 itself.
[0065] In addition, each optical module 21 is advantageously provided with first LEDs 23 mounted on the first printed circuit board 22 and first collimation means 24 placed frontally with respect to the first LEDs 23 to intercept light beams susceptible of being emitted by the first LEDs 23 and adapted to collimate the light beams along said first optical emission axis Y.
[0066] In particular, in order to facilitate the assembly of the support body 6 and of the first light sources 10, each optical module 21 is mounted on the corresponding lateral wall 16 before the aforesaid lateral walls 16 are fixed to the base support 12 and to the top support 14.
[0067] Advantageously, the first collimation means 24 comprise collimation lenses 45, each of which placed frontally with respect to a corresponding first LED 23 mounted on the first printed circuit board 22 to intercept light beams emitted by the aforesaid corresponding first LED 21 in order to collimate them along the first optical axis X of the first light source 10.
[0068] In accordance with the preferred embodiment illustrated in the enclosed figures, each optical module 21 comprises at least one retention element 25 placed frontally in abutment against the first collimation means 24, fixed to the first printed circuit board 22 and arranged for maintaining the first collimation means 24 in position with respect to the first LEDs 23.

[0072] In addition, the present light indicator 1 comprises an electronic control unit operatively connected to the first LEDs 23 and arranged for selectively driving the turning on and off of the first groups of first LEDs 23.
[0073] In this manner, the present light indicator 1 can be advantageously employed as semaphore for communicating to the pilot of an aircraft vehicle the possibility or impossibility of landing on the landing platform or runway by selectively actuating one of the first groups of first LEDs 23, i.e. by selecting to emit red, blue or amber light beams.
[0074] Advantageously, the present light indicator 1 comprises second light sources 26 mounted on the support body 6 at the top portion 8 and having a second optical emission axis Z thereof substantially parallel to the extension direction X of the support body 6.

Preferably, the support plate 27 is placed spaced from the top flange 14, defining a first interspace 28 communicating with the hollow volume by means of the second opening 19 of the top support 14.
[0077] In this manner, the first interspace 28 allows the passage of air within the hollow volume defined between the lateral walls 16 from above, even if the second light sources 26 are arranged at the top portion 8.
[0078] Advantageously, the support body 6 comprises one or more first spacer elements 29, each of which extended along a first main direction thereof between a third end fixed to the top flange 14 and an opposite fourth end fixed to the support plate 27.
[0079] Advantageously, the second light sources 26 comprise at least one second printed circuit board 32 fixed to the support plate 27, multiple second LEDs 33 mounted on the second printed circuit board 32 and second collimation means 34 placed across from the second LEDs 33 and mounted on the second printed circuit board 32.

[0083] Advantageously, the present light indicator 1 is provided with a coupling frame 35 comprising at least one support wall 36, which is extended transverse to the extension direction X of the support body 6 and carries, mounted thereon, the base body 3 of the containment casing 2, and a coupling portion 37, which is extended protruding from the support wall 36 adjacent to the containment casing 2.
[0084] In particular, the coupling portion 37 is intended to be mechanically coupled adjacent to a landing platform, in a manner such that the support wall 36 is placed below with respect to the height of the same landing platform. In this manner, the height by the light indicator 1 is reduced, i.e. in particular with transparent portion 5, that projects with respect to the landing platform and which could interfere with the movements of the aircraft vehicles in landing or take off.
[0085] More in detail, the support wall 36 is extended orthogonal to the substantially vertical extension direction X of the support body 6 and, therefore, once the light indicator 1 is installed through the coupling frame 35 on a landing platform, such support wall 36 is intended to be placed horizontally.
[0086] Preferably, the bottom wall 38 of the base body 3 of the containment casing 2 is fixed to the support wall 36 by means of bolted connection.
