Description

The subject of the invention is a composite light pole that can be used in places that do not require intense lighting. This pole can be used as an energy pole, traction pole, lighting mast, structure supporting structure, supporting structure of footbridges and bridges, and also as a roof structure. The solution according to the invention will also find application for marking water routes or other difficult to maintain communication routes. The developed pole can be used both outside and in utility interiors, such as shopping malls or single-family houses.

From the Polish description of the utility model application with the number W. 110939, we know the solution entitled: "Pole, especially advertising" (publication BUP 23/2001 of 2001-11-05). The design of the column, especially the advertising one, is characterized by the fact that it is preferably in the form of a pipe made of a composite of glass mat and polyester resins, provided with a plug and a foundation flange, which inside has lashings attached to the brackets located on the inner surface of the plug and on the foundation flange.

Another Polish description of the patent application No. 404396 discloses the solution: "The method of joining composite sections forming the boom of a lighting column and a composite boom manufactured in this way" (BUP publication 01/2015 of 2015-01-05). The subject of this solution is the method of joining composite profiles forming the extension arm of the lighting column, characterized in that for joining two consecutive composite profiles, an elbow connector with an appropriate bend angle is used, which is connected to the mentioned profiles using a polymer binder with a filler in the form of granules. with abrasion-resistant properties and high hardness. The invention also relates to a composite lighting pole boom, which uses the said method of joining composite profiles.

The composite pole presented by the company "ALUMAST" sp. Z o.o. is also known. in 2008 during the Polish Energetab fair in Bielsko-Biała, and in 2010 during the Infrastructure fair in Warsaw.

The aim of the developed invention is to create a new type of composite pole structure, which will illuminate the area in the basic scope and it will not be necessary to supply it with electricity, or it will be sufficient to supply it with electricity only to a minimum extent.

The essence of a composite light pole, the main structural element of which is a tube-shaped shaft, and which is made of a composite essentially of glass-polyester resin, usually chemically cured, and of glass fibers, is that it contains a phosphor which makes up 2% to 8% mass of the column structure. Most preferably, the composite comprises a minimum of 3% by weight of a glow-effect filler. On the other hand, preferably powders are used as luminescent materials in which the grain size of the filler is between 10-40 micrometers.

Preferably, a light source is installed inside the stem tube, which is preferably a LED lamp emitting low-power visible white light, i.e. 1 to 5 Watts [W] (Watt).

Preferably, the composite light pole is provided with a louvre and the phosphor is blended with the blend forming the outer coating.

Preferably, the composite light pole is connected to a motion detector that is part of the pole or is placed near it.

Preferably, the shank is surrounded by an outer coating which is made of a gel coat and is colorless, colored, or with a fully or partially printed coating, where a phosphor is added to the gel coat mixture made of composites, which makes up from 2% to 8 % by weight of the column structure, the composite most preferably containing at least 3% by weight of a glow-effect filler, while preferably powders with a grain size of the filler between 10-40 micrometers are used as luminescent materials.

The developed, composite light pole enables easy illumination of the area in places that do not require intense brightening. The installation of the developed pole is uncomplicated due to the fact that there is no need to supply it with electricity. The developed structure enables visual tracking of a path or road at night, which improves the safety conditions for people walking on them after dark. The invention allows to limit the lighting infrastructure and reduce lighting costs. Additionally, the developed pole can be used in areas endangered by seismic shocks and in other places exposed to power disconnection. The invention provides for the possibility of integrating it into the landscape, because the developed composite light pole can be decorated with graphics, according to the user's preferences, printed on the pole, or embedded in its structure.

The solution submitted for protection also shows all the advantages of the already disclosed column made of polyester-glass mass and glass fibers. Due to the fact that the developed pole is light, its transport is uncomplicated, its assembly is also trouble-free, no hoop iron costs, low operating costs, because it does not degrade, does not corrode, does not change color, and does not require maintenance with paint. Due to the fact that the composite inspection door has no scrap value, it is not damaged. This column does not require periodic tests for insulation of the poles. It exhibits high mechanical resistance and, for example, absorbs some energy in the event of a collision. It is also resistant to UV rays, and its smooth surface makes it easy to remove dirt. The composite column also does not interfere with radio waves, microwave radars - which is important when it is used in airport infrastructure.

The developed composite light pole can be successfully used in housing estates, parks, bicycle paths, parking lots, pedestrian crossings, etc.

The subject matter of the invention is shown in more detail in the embodiment in the drawings, in which Fig. 1 shows an axonometric view of a composite light column, and Fig. 2 shows a cross-section of a composite light column.

As shown in the drawings, the main element of the composite light pole is the shaft 1, which is shaped like a tube, which is the main structural element of the column. The shaft 1 is made of polyester-glass resin, usually chemically cured, and of glass fibers, the composite containing a phosphor, i.e. a chemical substance with luminescent properties, which constitutes from 3% to 7% of the weight of the column structure. The resin used does not block the excitation bands or the emissions of the fillers used. The most favorable relationship between the level of filling and the intensity of light emission is achieved when composites with a content of min. 3% by weight of a filler showing a glow effect.

The luminescent materials used were powders in which the size of the filler grains is most preferably between 10-40 micrometers and depends on the type of substance used.

The shaft 1 is surrounded by an outer sheath 2 which is made of a gel coat. The outer coating 2 is colorless, colored and with a printed coating. A phosphor is also added to the gel coat mixture, made of composites, which, similarly, e.g. under the influence of the louvre 3 or the headlights of a passing car, is excited and emits a glow visible to the human eye, noticeable to the human eye after 2 hours from 15 minutes. excitation.

To induce the described phenomenon of luminescence - the phosphor does not need to be irradiated permanently. Its activation occurs after attacking the surface of the prepared column also with ultraviolet light. The light wave of this length is contained, for example, in white LED light or in the light of car headlights. A light source can also be used to induce the phenomenon, which will only generate a beam of ultraviolet light. Then the flashes of light that stimulate the phosphor will not be visible to the human eye and no one observing the pole will notice them, let alone be blinded.

The phosphor can be added both to the outer shell 2 and to the shaft 1. The developed solution allows to excite the phosphor temporarily so that the time of the produced glow is as long as possible.

The invention envisages the installation of an optional light source 4 placed inside the tube of the shaft 1, which may be, for example, an LED lamp emitting low-power visible white light, i.e. from 1 to 5 Watts [W] (Watt). In the event that the light pole is illuminated exclusively by a raster frame 3 and by car headlights, then the phosphor is mixed with the mixture forming the outer skin 2.

The construction according to the invention also provides for the installation of a motion detector 5, which is part of the pole or is located near it. The motion detector 5 reacts to movement within its range, thereby activating the raster luminaire 3 or the optional light source 4 which emit

A light beam containing an ultraviolet light spectrum, thereby exciting the phosphor contained in the composite light pole. The phosphor, stimulated in this way, emits a glow visible to the human eye and illuminates the area around the developed, composite light pole. Thanks to the use of a motion detector 5 to induce the described phenomena, it is possible to turn on the raster luminaire 3 only in the event of someone's movement, and therefore someone's presence, when there is a real need to illuminate a given area. At the same time, the phosphor is activated and therefore it is not necessary to periodically stimulate the phosphor. The operation of the composite light pole with the described structure saves both energy and structure.
