Definitions

  • This invention refers to devices and apparatuses for illuminating outdoor areas intended to the vehicle circulation, like roads and expressways, and more specifically concerns a road lighting and delineating apparatus in conformity with the principles and criteria outlined in the Italian regulations of the sector, defined by the UNI 11248 "Road lighting" standard. Illumination, whether indoor or outdoor, constitutes a fundamental element for guaranteeing safety and visual comfort.
  • the outdoor lighting apparatus known and widely used for road lighting like lampposts, street light towers, street lights, generally include a supporting pole or bracket, with one end fixed to the ground or to an adjacent construction and the other end destined to sustain a housing for a light source selected, for example, among incandescent light bulbs, high-pressure mercury vapor light bulbs, high- or low- pressure sodium vapor lamps, LED lamps.
  • a light source selected, for example, among incandescent light bulbs, high-pressure mercury vapor light bulbs, high- or low- pressure sodium vapor lamps, LED lamps.
  • the poles must be tall enough to position the light source at a height sufficiently elevated to allow the uniform illumination of the roadway, in total compliance with all legal requirements, and with a section diameter that grants sturdiness and stability to the entire lighting apparatus. More in detail, the law requires that the poles have variable heights according to the type of use, for example heights comprised between 8 and 12 meters for road and expressway lighting, so that the driver of a vehicle has optimal perception of both the roadway layout and the stopping distance from a potential obstacle present along the traveling lane or on the carriageway.
  • poles are made mainly of steel.
  • fiberglass makes it possible to obtain very lightweight poles that are easily handled, but having larger section diameters and therefore requiring very bulky supports, while the use of aluminum ensures a better guarantee of durability over time and is easier to work with, consequently this material can take on a wide variety of shapes, which is very popular in urban settings, but also implies higher production costs.
  • the light source positioned at a considerable height makes the maintenance thereof complex and in some cases dangerous. Indeed, when there is a breakdown or a malfunction of the lighting, a maintenance technician must reach the light source by climbing up the relative supporting pole or using a lift truck, thereby exposing himself to all the dangers that the option selected implies. Moreover, if ever the light source should detach from the supporting pole, for example in an area subject to strong gusts of wind, there is a very serious risk that it strikes either a vehicle or a person with a force directly proportional to its fall.
  • the higher the position of the light source the greater the probability that one or more dark zones or the so-called veiling luminance may appear on the asphalt, in the presence of rain or fog respectively. It is indeed known that the rain settled on the asphalt gives rise to zones that appear black to an observer, in particular where the lighting apparatus, the eye of the observer and the roadway are aligned (i.e. at the critical angle or Brewster's anglef), due to the fact that the light is reflected by the road surface outside of the observer's own field of view.
  • An object of the present invention is to improve the known lighting apparatus for illuminating and delineating outdoor areas, like streets and expressways, intended for vehicle traffic, in particular to realize a road lighting and delineating apparatus that is in conformity with the regulations of the sector, free from the drawbacks described above and at the same time simple and economical to construct.
  • Another object is to provide a road lighting and delineating apparatus with moderate dimensions, with no supporting pole or bracket and suitable to be installed on essentially vertical surfaces like, for example, a tunnel wall, the surface of a Jersey barrier, or the band of a guardrail.
  • Yet another object is to realize a road lighting and delineating apparatus that improves visual comfort, and hence traffic safety, and supports the orientation of the driver under any weather conditions and, in particular, in the presence of rain and/or fog.
  • Another further object is obtain a road lighting and delineating apparatus that does not constitute an obstacle in case of impact by a vehicle, thereby minimizing the consequences for both the driver and the passengers of the vehicle in question.
  • FIG. 1 is a perspective view of a first embodiment of the road lighting and delineating apparatus according to the present invention
  • FIG. 2 is a perspective view of the road lighting and delineating apparatus of Figure 1, with some parts removed for the sake of clarity;
  • FIG. 3 is a side view of a second embodiment of the road lighting and delineating apparatus according to the present invention.
  • FIG. 4 is a side view of the road lighting and delineating apparatus of Figure 1;
  • FIG. 5 is a side view of the road lighting and delineating apparatus of Figure 1 , mounted on a guardrail;
  • FIG. 6 is a perspective view of two road lighting and delineating apparatus according to the present invention mounted on a guardrail;
  • the figures illustrate a road lighting and delineating apparatus 1 according to the present invention, which can be installed on a supporting structure 10 at a set installation height H from a road surface S, which includes a central body 2 with a molded part 21 and a frontal wall 22 that is substantially transparent.
  • the central body 2 has an elongated shape, more specifically the shape of a rectangular parallelepiped with a trapezoidal section, extends in a longitudinal direction A and is provided with a cavity 23 with an opening 25 on at least one of two sides 24 opposed to each another and transversal to said longitudinal direction A.
  • the molded portion 21 and the frontal wall 22 may be in a single body or the central body 2 may form a monolithic element.
  • the molded portion 21 and the frontal wall 22 can be separated and destined to be coupled to form the central body 2 with the cavity 23.
  • the molded portion 21 of the central body 2 is equipped with an external seat 20, that in the embodiments illustrated in the figures is opposite the frontal wall 22, and can be engaged with a fixing element 27, comprising for example a bracket intended to be fixed in an adjustable and reversible way to the supporting structure 10, such as the wall of a tunnel, a surface of a Jersey barrier, a band of a guardrail, as in the example illustrated.
  • the bracket 27 can be fixed by using a suitable bolt in a slot present on the lower curve of the band of the guardrail 10 as illustrated in Figures 5 and 6, or by means of a suitable clamp when the bracket has the same shape as the profile of the guardrail 10 itself.
  • the central body 2 can be housed in this latter in a compact assembly configuration G that is particularly advantageous, in which the volume of the apparatus 1 is notably reduced, in particular without protruding from the guardrail itself.
  • the bracket 27 can be fixed in an adjustable way to the supporting structure 10, in a way known by a person skilled in the field and not further explained here in detail, in such a way as to be able to suitable orient the apparatus 1, in particular inclining it on a vertical plane of an angle, for example of 15°, according to said installation height H from the road surface S. Consequently, the apparatus 1 can be positioned at a set installation height H according to particular road conformations, like curved stretches that require specific attention in controlling the lighting, especially at an installation height H less than 150 cm, for instance equal to 80 cm.
  • the road lighting and delineating apparatus 1 includes at least one blind plug 3 with an operational surface 30, designed to be reversibly coupled with the central body 2 at said opening 25 so as to close, preferably hermetically, the cavity 23.
  • the central body 2 is provided with a plurality of threaded holes while the blind plug 3 is provided with a corresponding plurality of through holes; in this way the coupling can be simply carried out by means of screws that pass through the holes of the blind plug 3 and screw into the threaded holes of the central body 2.
  • the blind plug 3 can be coupled with the central body 2 by interlocking or using magnetic coupling devices.
  • a road delineating system for example a passive signaling system namely a reflector or retroreflector 31 to signal the presence of an obstacle as represented by the supporting structure 10 to which the apparatus 1 is fixed or the apparatus 1 itself.
  • the operational surface 30 can house an active road delineating system, as depicted in the second embodiment illustrated in Figure 3, for example, a module or board 32 with a plurality of further LEDs 33 to delineate exits, curves, dangerous stretches, rotaries, intersections, to support the orientation of a driver in case of fog and warn him promptly of the presence of accidents or roadway construction sites.
  • a lighting system 4 is housed inside the cavity 23 and comprises at least one LED 41
  • the LED 41 is mounted on a respective printed circuit 47 which is slidably coupled to the supporting means 42 positioned inside the cavity 23 and connected to the central body 2, for example to a rear wall 26 of the molded portion 21 opposite the frontal wall 22.
  • the printed circuit 47 that is the LED 41, sliding along the supporting means 42 can be stably positioned in a suitable position inside the cavity 23.
  • the supporting means 42 are also conveniently constructed in thermally conductive material, for example in aluminum, so as to act also as a heat sink for the printed circuit 47.
  • the printed circuit 47 is equipped with a length of cable, not shown in the figure, that comes out of the apparatus 1 through, for example, a gland for the connection to an electric grid system or to power supplying means for the LED 41.
  • the refractive lens comprises for example a plastic refractive lens 43 and is suitably molded according to the LED 41 to emit a light flux F directed towards the frontal wall 22. More in detail, the refractive lens 43 shows a substantially elliptic section on a primary plane PI and an asymmetric oblong section on a secondary plane P2 almost perpendicular to the primary plane PI.
  • a centered optical system for which an optical axis is defined, as is known to a person expert in the field, two luminous homocentric rays that propagate along respective directions that lay on the primary plane PI and are symmetric to each other in relation to the optical axis (by definition the optical axis joins the geometric center of the refractive lens 43 and the center of the rays), by impinging on the refractive lens 43 they propagate along directions that are still symmetrical in relation to the optical axis itself.
  • the reflective optical system 44 responsible for optimizing the overall performance of the apparatus 1, comprises a reflecting body 45 and a couple of fins 46.
  • the reflecting body 45 on a plane orthogonal to the primary plane PI and secondary plane P2, has a parabolic cross section that extends along the longitudinal direction A and is secured to the printed circuit 47 or to the heat sink.
  • the section of the reflective optical system 44 is asymmetrical, as it is shorter on one of the two branches of the parabola, advantageously on the branch closest to the road surface S as in the embodiment illustrated in Figures 4 and 5.
  • the reflecting body 45 and the fins 46 are equipped with respective reflecting surfaces, for example in silver-coated aluminum with high performance (greater or equal to 98%), which constitute an internal surface of said hollow body.
  • the reflective optical system 44 is capable of reflecting part of the light flux F emitted by each refractive lens 43 and potentially dispersed, and directing also this part towards the frontal wall 22.
  • the fins 46 have the further function of reducing the potential dazzle generated by each refractive lens 43. As a consequence, the dispersion of light is limited and the overall performance of the apparatus 1 is optimized.
  • the light rays L emitted by the LED 41 are refracted by the refractive lens 43 and reflected by the reflective optical system 44 in order to obtain the light flux F that is grazing said road surface S and conform to the regulations of the sector.
  • the apparatus 1 comprises a plurality of LEDs 41 distributed along a direction parallel to the longitudinal direction A, preferably equidistant from one another.
  • These LEDs 41 can be mounted on a printed circuit 47 or on respective printed circuits 47, in both cases a respective refractive lens 43 and a respective reflective optical system 44 being associated to each LED 41.
