Definitions

  • the present description relates to lighting devices.
  • One or more embodiments may be employed, for example, in streetlighting applications.
  • the target values of these parameters may vary according to the different road classifications (ME1, ME2, S1, CE0, %) and according to various factors (pole interspacing, pole height, etc.) which may impact on performance levels.
  • Various implementations may involve the use of light radiation sources, e.g. solid-state LED radiation sources, combined with lenses.
  • Each lens is adapted to provide a certain radiation pattern, with the possibility to fulfil road requirements in terms of light distribution on the road surface: by increasing the number of sources and lenses it is possible to increase the lighting flux up to the level required by the standards.
  • Some implementations envisage a combination of different types of lenses (e.g. with different lighting patterns) and the assembly ("convolution") of the various radiation patterns originates the required final radiation pattern.
  • the first important factor is the distance of the lens from the light radiation source: factors such as the temperature of the lens and/or the blue light density, for example from a LED, may degrade the performance of the polymer which forms a polymeric lens.
  • glass lenses may solve some of these drawbacks, but it may involve disadvantages as regards design and cost constraints.
  • a given lens may be optimized only for a specific source of light radiation, e.g. only for one specific LED.
  • some lighting sources may be visible from all directions and cause discomfort to observers, with a possible undesired light spillage at high angles.
  • reflectors may be freeform reflectors for clustered solutions, or small freeform/conic shaped reflectors which are coupled to each light radiation source in distributed solutions.
  • a drawback of these solutions regards optical efficiency, which may be reduced by multiple reflections and by the limited reflectivity of the reflector (usually about 85%).
  • the invention relates to a lighting device according to the preamble of claim 1, which is known e.g. from GB 2 024 397 A .
  • Other documents of interest for the invention include, e.g.: US 6 382 803 B1 , WO 2010/016118 A1 , US 2007/206384 A1 , US 4 694 382 A and US 2008/219008 A1 .
  • One or more embodiments aim at overcoming the previously outlined drawbacks.
  • said object is achieved thanks to a lighting device having the features specifically set forth in the claim 1 that follows.
  • One or more embodiments may also refer to a corresponding method.
  • Figure 1 shows a possible application context of one or more embodiments, specifically in the field of technical street lighting.
  • Figure 1 shows a part of a road S, of indefinite length, having a width w and being lit by luminaires 10 mounted e.g. on poles P.
  • luminaires 10 may be separated by distance i, may be placed at a height h and may be mounted on poles P having the base at a certain distance from the edge of the road.
  • luminaires 10 may comprise (e.g. mounted in a respective housing, not visible in the Figures) a reflector body 12, e.g. of a molded material, such as a lightweight metal material or plastic.
  • Reflector 12 is designed to be coupled to a light radiation source L adapted to comprise for example an electrically powered light radiation source.
  • the source is an LED source mounted on a PCB (Printed Circuit Board, not visible in the drawings).
  • light radiation source L may be designed to be placed in a given position, marked by point F.
  • source L will hereinafter be identified with point F, therefore assuming for simplicity the presence of a point-shaped light radiation source.
  • the reflector 12 may have the function of reflecting the light emitted from light radiation source L, arranged in position F, towards an illumination space adapted to be identified, for instance, with road surface S.
  • reflector 12 has an internal reflective surface having a substantially ribbon-like shape, possibly of a constant or substantially constant height.
  • Said reflective surface is therefore ideally enclosed between two end planes.
  • light radiation source L (point F) is placed at one of such end planes, i.e. it may lie in one of such planes or in the vicinity thereof.
  • the light radiation emitted from source L may propagate towards said reflective surface, in order to be reflected thereby (according to ways described in the following), so as to be projected out of luminaire 10 towards the illumination space, i.e. the space that must be lit (for example road surface S of Figure 1 ).
  • reflector 12 may have itself a generally ribbon-like shape. Said ribbon-like reflective surface may then be simply comprised of the inner surface of reflector body 12, shaped and/or treated (e.g. with an aluminising treatment) so as to have (high) reflectivity.
  • said reflective surface is a multi-faceted surface, comprising several reflective sides or facets.
  • said multi-faceted reflective surface may comprise:
  • each of the front 120, back 122 and end 124 sides is shaped and/or oriented so as to reflect the radiation coming from radiation source L, while directing it in a different direction of the illumination space.
  • said multi-faceted reflective surface comprising sides or facets 120, 122 and 124 may be an annular surface, e.g. with the shape of a closed loop.
  • all said multi-faceted surface may be reflective. In one or more embodiments, said multi-faceted surface may comprise separating portions between reflective portions.
  • the front 120 and back 122 sides, on one hand, and the end sides 124, on the other hand may constitute respectively the major and the minor sides of a multi-faceted reflective surface the plan view whereof is an approximately rectangular broken curve, the light radiation source L (point F) being arranged approximately in the middle (see for example the plan view of Figure 2 ), i.e. in a central symmetry plane of the reflective surface.
  • the multi-faceted reflective surface comprising facets or sides 120, 122 and 124 has on the contrary a substantially asymmetrical plan view.
  • each of the sides 120, 122, 124 constitutes a portion of the (internal) reflective surface of reflector 12, being able to reflect the light radiation of source L towards the illumination space in an independent way, i.e. via a single reflection: for example, a ray emitted by radiation source L meets the reflective surface only once.
  • the front side 120, the back side 122 and each of the end sides 124 of the reflective surface is so to say “dedicated” to sending the light radiation reflected thereby towards a direction of the illumination space which corresponds to a respective area of road surface S.
  • one or more embodiments as exemplified herein may be used in a context as the one explained with reference to Figure 1 , wherein the height h of poles P approximately corresponds to the width w of road S, and the distance i separating poles P (i.e. luminaires 10) is approximately 3-4 times the height h.
  • a reflecting mechanism may be implemented whereby at least some of the light beams reflected by the various facets or sides 120, 122 and 124 may cross each other on the propagation path in the illumination space.
  • illumination beams L3 reflected by sides 124 and directed towards the end regions S3 may cross while exiting luminaire 10, so that (referring by way of example only to the arrangement of Figure 9 ):
  • illumination beams L1 and 12 reflected by front side 120 and back side 122 may cross while exiting luminaire 10, too, so that, always referring by way of example only to the relative arrangement shown in Figures 10 and 11 :
  • Figures 6 to 8 exemplify various criteria which may be used, in one or more embodiments, to implement sides 120, 122 and 124 of the multi-faceted reflective surface of reflector 12 according to parametric curves (ellipsoids, parabolas, spheres).
  • the reflective surfaces which correspond to the end sides 124 may be implemented so as to have a parabolic surface (a paraboloid), the focus of the parabola being disposed at point F where light radiation source L is arranged, and the axis of the parabola/paraboloid which describes the profile of said parabolic surface being oriented so as to direct the reflected radiation for example towards the areas S3 of the road surface which are farthest away from the mounting position of luminaire 10.
  • a parabolic surface a paraboloid
  • one or more parabolic profiles may be used, according to the space which must be lit, with the possibility of aiming each parabolic profile towards a different target area.
  • the Figures exemplify moreover, with reference to the front side 120 and the back side 122, the possibility to give the sides of the reflective surface a further multi-faceted shape, wherein one or more sides 120, 122 and 124 of the multi-faceted reflective surface comprise in turn several portions or parts.
  • front side 120 may have a general gull-wing shape, with two symmetrical portions (referring to an ideal plane passing through point F) each of which comprises:
  • proximal and distal refer to the relative arrangement with respect to source L.
  • At least one of the sides may be implemented as a Fresnel reflector, i.e. with a reflective surface divided into various facets F1, F2, F3, ... each of which may be named a "Fresnel facet”.
  • various facets F1, F2, F3, ... may be oriented vertically with respect to the lying plane of source L.
  • the profile of the facets of the Fresnel reflector may be described by a parametric curve.
  • each Fresnel facet may be described by a parabolic equation, wherein the focus of the parabola may be arranged at point F, where the light radiation source L lies, and the axis of the parabola/paraboloid describing the profile of the facet surface may be oriented so as to direct the reflected radiation towards a respective portion SF1, SF2, SF3 (see Figure 5 above) of road surface S, i.e. in a respective direction of the illumination space.
  • Figure 8 exemplifies how such a parametric criterion may be applied to different sides, so that for example the radiation reflected by one of the end sides 124 and the radiation reflected by the distal portion 120c of front side 120 are directed towards respective portions S3 and S31 of road surface S, therefore, once again, in respective directions of the illumination space.
  • one or more sides of the reflective surface may optionally be filled with so-called “pillows” in order to broaden and smooth the light distribution.
  • the reflector body 12 may be formed by two parts 12a, 12b, which may be adapted for example to be coupled on a plane which is parallel to the lying plane of a PCB on which the light radiation source L is mounted.
  • Alignment pins 12c may optionally be provided which may insert in corresponding openings 12d, as exemplified in Figure 12 .
  • Figures 12 and 13 further highlight the broken line shape of the plan profile of parts 12a and 12b.
  • both parts 12a, 12b by snap-fit formations, e.g. comprising spring teeth 12e engaging corresponding eyelets or openings 12f.
  • One or more embodiments as exemplified herein overcome possible limitations due to the distance from the light radiation source, because they enable an arrangement of the reflective surfaces at a farther distance from the light radiation source than it would be possible with a lens. The consequence is a lower irradiation of the optical surfaces, with a lower operating temperature and a lower light absorption in the blue range.
  • the use of a reflector may be competitive in terms of cost as compared to the use of lenses, both in extended light radiation sources and in clustered or spread sources.
  • the light radiation emitted by the source is optically masked by the reflector, i.e. it is not visible by an observer practically from all viewpoints. This is particularly true for angles of 75-90° with respect to the reflector axis, which reduces the glare perceived by the observers as compared with lenses.
  • One or more embodiments may show a reduced sensitivity towards manufacturing and assembling tolerances, for example because the parametric focal distance is higher in comparison with mechanical tolerances.
  • the possibility to implement reflective sides 120, 122, 124 as parametric reflectors may simplify the design from an optical point of view, because it requires the handling of fewer parameters (focus, curvature, aiming direction), therefore simplifying the designing activity.
  • explicit equations are available to determine the projection of source L in the illumination space (e.g. on the lit road surface) given the position of the radiation source.
  • the fractioning of the reflective surface e.g. the creation of Fresnel facets that are oriented vertically with respect to the light radiation source F, allows for tailoring the light source in the different areas of the lighting space, e.g. on the road surface to be lit.
  • each surface portion e.g. each Fresnel facet
  • each surface portion e.g. each Fresnel facet
  • One or more embodiments achieve a high optical efficiency as well, because the reflector does not cover the light radiation source completely.
  • the reflective source acts mainly through single reflection interactions, with the possibility for example to use the various elements of the reflector (e.g. various Fresnel facets) to direct the light radiation in controlled directions in the illumination space, enabling to direct a higher amount of light towards the illumination space.
  • the various elements of the reflector e.g. various Fresnel facets
  • One or various embodiments offer a high level of flexibility in tailoring the radiation pattern: providing independent reflective portions (for example independent Fresnel facets, each operating on a respective portion of the radiation pattern) makes it easier to adapt to different road scenarios.
  • independent reflective portions for example independent Fresnel facets, each operating on a respective portion of the radiation pattern
  • one or more embodiments may be used in contexts wherein, as previously mentioned, the mounting height h of luminaires 10 approximately corresponds to the width w of road surface S, and the distance i between neighbouring luminaires 10 amounts for example to 3.5 times the height h. Moreover, the possibility is given to adapt the amount of "overhang" of luminaire 10 projecting above the road surface (which is given by distance o of Figure 1 ) and of a possible tilting.
