Abstract
Description
- The present invention concerns a light signaler usable to signal obstacles.
- In particular, the present invention is applied for example to signal obstacles in airports, towers, tall buildings, chimneys, smokestacks, torches, bell towers and similar and comparable obstacles.
- Light signalers are known which comprise a tubular-shaped support body extending in a longitudinal direction and a light source associated with the support body.
- The light source usually comprises a support plate on which a plurality of LEDs are attached.
- The support body, in turn, is provided with heat dispersion elements, usually fins, provided to dissipate the heat generated by the light source. The heat dispersion elements can be made in a single body with the support body, or integrally attached thereto.
- It is also known that the light signalers comprise a deflector attached to the support body and configured to deflect the light beam emitted by the LEDs.
- In particular, the deflector usually has the function of collimating the light emitted by the LEDs into light beams with a direction parallel to the desired emission plane, that is, in a direction perpendicular to the longitudinal axis of extension of the light signaler. In particular, one of the characteristics of the deflector is that it has a high ability to collimate the light, that is, to direct the rays in the desired direction, avoiding as much as possible dispersion and optical diffusion phenomena. In this way, the light emitted is visible at a greater distance and allows to avoid distortions that would not make the position of the obstacle precisely definable.
- Furthermore, known light signalers comprise a closing body attached to the support body, having a globe shape and made of transparent material to allow the passage of the light beam deflected by the deflector.
- This configuration of the closing body, however, causes phenomena of aberration of the light beams. The curvilinear surface of the closing body, in fact, diverts the light rays in an undesired way, with consequent loss of effectiveness of the light signal itself. Furthermore, the shape of the closing body makes its manufacturing operations particularly complex and expensive.
- The closing body defines with the support body a chamber closed toward the outside in which the light source and the deflector are positioned, protecting them from the external environment.
- Usually, sealing elements are provided between the closing body and the support body, with the function of isolating the chamber with respect to the outside. This makes the light signaler particularly suitable to be applied in operating environments where explosive atmospheres can be present, or more generally deflagrating or explosive powders or substances, such as can be found on oil platforms, or other similar structures.
- In these cases, the light signalers have to guarantee an adequate degree of safety and in particular prevent accidental formation of discharges between the electrical components of the power supply body from acting as a detonator for the deflagrating powders or substances present in the environment, with consequent accidents or explosions.
- The known solution described above, due to the particular conformation of the closing body, does not allow to optimize heat dissipation.
- Furthermore, the known light signalers described above are very bulky.
- Another disadvantage of known light signalers is the difficulty in assembling and manufacturing the various components of which they consist.
- One purpose of the present invention is to provide a more economical light signaler.
- Another purpose of the present invention is to provide a light signaler able to significantly reduce light aberrations with respect to the state of the art.
- It is also a purpose of the present invention to provide a light signaler which has a shape which allows a more effective dispersion of heat.
- It is also a purpose of the present invention to provide a light signaler more compact in size.
- The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
- The present invention is set forth and characterized in the independent claims, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.
- In accordance with the above purposes, a light signaler according to the present invention, comprises:
- a support body,
- a light source associated with the support body, and provided with a plurality of LEDs,
- a deflector attached to the support body and provided with a shaped deflection surface facing, during use, toward the light source in order to deflect the light beam emitted by the LEDs.

- In this way it is possible to obtain a light signaler that, with respect to known solutions, is extremely easy and economical to produce.
- The presence of a tubular-shaped closing body, advantageously cylindrical in shape, allows to avoid the phenomena of optical aberration, thus increasing the efficiency of the light signaler.
- The present invention therefore provides a light signaler with high deflagration-proof characteristics.
- According to the present invention, therefore, the support body, the closing body and the deflector are connected to each other defining structural components of the light signaler that insulate, with respect to the outside, the chamber in which the light source is housed.

attachment elements 21 are configured to close the closingbody 24 pack-wise between thedeflector 19 and thesupport body 11, to contribute in conferring deflagration proof properties on the assembly. Advantageously, the pack-wise configuration allows a greater resistance to a possible deflagration inside thechamber 25, guaranteeing and maintaining at the same time the structural solidity of the light signaler, its optical functionalities for a correct lighting, and the safety of the surrounding environment. - According to a possible solution, at least one of either the
support body 11 or thedeflector 19, in this case both, is provided with ahousing throat 22 in which, during use, the closingbody 24 is positioned. - According to a possible solution, the
housing throat 22 can have sizes suitable to accommodate the thickness of the closingbody 24. - According to a possible solution, the
light signaler 10 can be provided with sealingelements 26 interposed between thedeflector 19 and the closingbody 24, and between thesupport body 11 and the closingbody 24, in order to insulate thechamber 25 with respect to the outside. - This solution makes the
light signaler 10 suitable for deflagration proof applications. - According to a possible solution, the sealing
elements 26 can be chosen from a group comprising cemented joints, or gaskets. - According to a further embodiment, the sealing
elements 26 can be provided in thehousing throats 22. - According to a possible solution, the
support body 11 is provided, in its thickness, with achannel 27 which extends toward the inside of thechamber 25 to allow the passage of cables to power thelight source 12. - According to a possible solution, the
channel 27 can be provided with a sealingbody 28 provided in order to allow the passage of power supply cables, not shown, toward thechamber 25, and in any case guaranteeing the insulation of thechamber 25 from the outside, possibly also explosion proof with particular reference to applications intended for zones with dangerous atmospheres. - The sealing
body 28 can be chosen from a group comprising a cable gland, a sealed joint, or similar and comparable elements. - According to possible solutions, the
light signaler 10 can be provided withpower supply components 34, connected to thelight source 12 through said power supply cables disposed through thechannel 27 and configured to supply electric energy to thelight source 12. - The
power supply components 34 can be chosen from a group comprising a terminal board, as shown infig. 3 , a power supply, a transformer, or other electrical components. - According to a possible solution, not shown, the
power supply components 34 can be associated with thesupport body 11, for example positioned in a housing seating made in the latter. - According to some embodiments, shown in
figs. 1-3 , thelight signaler 10 comprises asupport base 29 on which thesupport body 11 is attached and provided to allow the attachment of the latter with respect to a fixed wall of the final usage seating. - The
support base 29 can be provided with ahousing compartment 33 in which thepower supply components 34 are positioned to protect them from the outside. - The
housing compartment 33 is put in communication with thechannel 27 of thesupport body 11 to allow the passage of the power supply cables. - According to a variant embodiment, the
support base 29 comprises, in this case, aconnection component 31 and anattachment component 32 connected to each other, for example by means of threadedelements 30. - The
connection component 31 and theattachment component 32 can define between them thehousing compartment 33. - It is clear that modifications and/or additions of parts may be made to the light signaler as described heretofore, without departing from the field and scope of the present invention.
- It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of light signaler, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
