Definitions

  • the present description relates to reflectors for lighting devices.
  • One or more embodiments may refer to reflectors which may be employed in generating a "wall-washing" lighting pattern, by using electrically-powered light radiation sources, e.g. solid-state light radiation sources, e.g. LED sources.
  • electrically-powered light radiation sources e.g. solid-state light radiation sources, e.g. LED sources.
  • Wall-washing lighting may be improved by specific conditions of light radiation distribution and uniformity of the (laterally) projected illumination, so that the illuminated wall is “washed” by light.
  • This result may be achieved by using e.g. optics designed in order to achieve the required performances, especially as regards the radiation pattern, so that different radiation patterns may require customized optical devices, e.g. reflectors.
  • the invention relates to a reflector according to the preamble of claim 1, which is known, e.g. from US 4 799 136 A . Also documents US 2010/284181 A1 , FR 898 886 A , EP 2 175 194 A1 , EP 2 565 529 A1 and WO 2009/094819 A1 are of interest for the invention.
  • said object may be achieved thanks to a reflector having the features specifically set forth in claim 1 that follows.
  • One or more embodiments may also concern a corresponding device, as well as a corresponding method.
  • reference 10 generally denotes a lighting device, in a section across an approximately median plane.
  • Device 10 is adapted to be employed in wall-washing applications, with the purpose of obtaining a distributed and uniform lighting of a wall W (schematically shown in dashed lines).
  • device 10 may be mounted on a ceiling, e.g. as a spotlight embedded into a false ceiling, in conditions that may be considered as approximately rotated by 180° upside down with reference to the orientation used for simplicity of illustration in Figure 1 .
  • device 10 may comprise a body 12 (e.g. of a metal or heat-conductive plastic material, optionally finned in order to act as a heat sink) whereon there may be mounted an electrically-powered light radiation source L.
  • a body 12 e.g. of a metal or heat-conductive plastic material, optionally finned in order to act as a heat sink
  • the source may be a solid-state light radiation source, e.g. a LED source.
  • source L may have a planar shape, e.g. an at least approximately disk-like shape, having a Light Emitting Source (LES) adapted to include for instance an e.g. circular array or cluster (see Figure 1 ) of single LEDs lying in a common plane, the latter defining said emitting surface.
  • LES Light Emitting Source
  • source L may envisage the use of other light radiation sources L, especially as regards the shape and configuration thereof (e.g. planar sources of square, rectangular, mixtilinear shapes of various nature, etc.).
  • light radiation source L may be a LED source of the kind known as Chip on Board (CoB).
  • device 10 may include a reflector 100 adapted to achieve a wall-washing lighting pattern from the light radiation generated by source L.
  • reflector 100 may comprise a body e.g. of a moulded plastic material.
  • reflector 100 may have a tubular shape.
  • the body of the reflector may be traversed by a cavity 102 for propagating the light radiation, adapted to define a propagation path of the light radiation produced by source L between a (e.g. planar) light radiation injection aperture or window, denoted as 104, and a (e.g. planar) light radiation emission aperture or window, denoted as 106.
  • a (e.g. planar) light radiation injection aperture or window denoted as 104
  • a (e.g. planar) light radiation emission aperture or window denoted as 106.
  • the light radiation injection window 104 and the light radiation emission window 106 may lie in respective planes X104 and X106, the plane X106 of the light radiation emission window 106 being perpendicular to an axis X100.
  • Axis X100 may be, at least approximately, identified as a main axis of reflector 100.
  • axis X100 may correspond to the central axis of body 12, e.g. when the latter has a generally cylindrical structure.
  • axis X100 may correspond to a main axis of the device, and the light radiation source L (which, thanks to the planar structure thereof, may actually lie in plane X104 of injection window 104) may be seen as generally shifted, i.e. located in an eccentric (off-axis) position relative to said axis X100, e.g. by an amount denoted as A in Figure 1 .
  • axis X100 may not be the main geometrical axis of the device, while keeping however the role of an (optical) axis of reflector 100, as it identifies the general orientation direction of reflector 100 relative to wall W (see e.g. Figure 1 ).
  • the lying planes X104 and X106 of the light radiation injection window 104 and of the light radiation emission window 106 may define a dihedron having a dihedral angle of width ⁇ .
  • width ⁇ may amount approximately to 25°.
  • the lying plane X104 of the light radiation injection window 104 and the lying plane X106 of the light radiation emission window 106 may therefore form a dihedron having a dihedral angle with width ⁇ , being tilted (i.e. slanting or sloping) with respect to each other.
  • the lying plane X104 of light radiation injection window 104 and the lying plane X106 of light radiation emission window 106 may also be parallel, i.e. they may not form any dihedron (or they may form a dihedron having a dihedral angle ⁇ substantially amounting to zero).
  • the propagation path the light radiation defined by cavity 102 may still be tilted relative to the direction identified by axis X100.
  • cavity 102 may have a generally flattened shape, thus including two reflecting surfaces 102a, 102b lying on opposed sides or bands relative to the light radiation injection window 104, so that they may lie on opposed sides or bands relative to light radiation source L.
  • the surfaces of light radiation propagation cavity 102 may be implemented or treated so as to have a light radiation reflectivity e.g. higher than 85%.
  • a reflector 100 may enable the generation of a light radiation output pattern from window 106 which is asymmetrical (non circular), e.g. with a distribution having an axis at approximately 30° in a plane C and at approximately 0° along orthogonal plane C.
  • Such a lighting distribution may be used for wall-washing applications, e.g. by employing a plurality of devices 10 according to one or more embodiments, arranged in a certain number (e.g. five devices 10) ad a distance of approximately 1 m from the wall (W in Figure 1 ) with a mutual distance of 1 m in the direction parallel to the wall.
  • a certain number e.g. five devices 10
  • the body of reflector 100 may include two complementary portions 100a, 100b divided by an intermediate plane extending parallel to axis X100.
  • the light radiation injection window 104 may be located in the first portion 100a, while the light radiation emission window 106 may be located in the second portion 100b.
  • a screen 100c in the intermediate plane between portions 100a and 100b there may be arranged a screen 100c (see Figure 4 ).
  • screen 100c may be permeable to light radiation, e.g. transparent, and adapted to avoid an accidental hand contact with source L, e.g. during the operation thereof.
  • screen 100c may include a diffusive screen with a (limited) scattering action, e.g. in order to improve the uniformity of the illuminance distribution projected onto wall W from device 10.
  • the body of reflector 100 may comprise a material at least partially impermeable to light radiation.
  • light radiation injection window 104 may therefore be masked, i.e. invisible, through the light radiation emission window 106 when reflector 100 is observed from the front in the direction of axis X100, i.e. in a direction orthogonal to the extension plane of the light radiation emission window 106 (see e.g. Figure 7 ).
  • Figures 9 to 13 show various options for the implementation of surfaces 102a, 102b of the light radiation propagation cavity 102.
  • substantially similar lighting results may be obtained by optionally acting on the tilting of reflective surfaces 102a and 102b, also in embodiments wherein plane X106 is parallel to plane X104.
  • the first reflective surface 102a may be implemented so as to extend towards the light radiation injection window 104, so as to form a sort of roof pitch projecting over the light radiation injection window 104.
  • the first reflective surface 102a may thus receive the light radiation injected into window 104 in a direction orthogonal to respective plane X104, so as to reflect it.
  • the second surface 102b (located on the opposite side or band from light radiation injection window 104) may extend away from window 104.
  • the second surface 102b may thus be impinged on by the light radiation emitted from source L, which:
  • both reflective surfaces 102a, 102b of cavity 102 may define a gap therebetween, such as to enable a direct reflectionless propagation of the light radiation from injection window 104 to emission window 106.
  • Figures 9 to 13 exemplify in more detail possible implementations of the above general criteria, by referring by way of example to embodiments wherein plane X106 is tilted or oblique relative to plane X104.
  • Figure 9 refers to the possible propagation path of the light radiation rays entering cavity 102 orthogonally to plane X104 of light radiation injection window 104.
  • Such a component of the light radiation injected into reflector 100 is subjected to a mirror-like reflection onto first surface 102a, and is then reflected onto surface 102b, so as to exit window 106 in a generally off-axis condition.
  • Figure 9 exemplifies the case of a light radiation cone (which may be e.g. a green-coloured radiation cone) emitted from the centre of source L, while the side bands or cones (which may correspond e.g. to red and blue emissions) are emitted from the edges of the light radiation emission surface of source L; in this exemplary case, one of said side cones (e.g. the red cone) only marginally touches reflective surface 102a, while the other (e.g. the blue cone) is subjected to a twofold reflection, substantially similar to the reflection of the central cone (which has been assumed as green).
  • a light radiation cone which may be e.g. a green-coloured radiation cone
  • the side bands or cones which may correspond e.g. to red and blue emissions
  • the condition exemplified in Figure 9 may also be considered as corresponding to components (rays) of the light radiation which are injected into reflector 100 at an angle ⁇ to axis X100 substantially corresponding to angle ⁇ of the dihedron formed by planes X104 and X106.
  • Figure 10 exemplifies conditions approximately corresponding to a direct (reflectionless) propagation of the light rays from injection window 104 to emission window 106.
  • This propagation path may be covered e.g. by light rays emitted by source L at an angle of approximately 30° to the normal to the light radiation emission window of source L, i.e. with an angle ⁇ amounting approximately to 55° relative to axis X100.
  • Figure 11 refers to light radiation components emitted by source L at an angle of approximately 65° to the normal to the light radiation emission surface (LES), i.e. at an angle ⁇ relative to axis X100 amounting approximately to 90°.
  • LES light radiation emission surface
  • the rays corresponding to such components of the light radiation impinge on the second surface 102b while interacting only marginally with the first surface 102a (e.g. on the sides of cavity 102, where surfaces 102a and 102b unite).
  • Figure 12 refers to components of the light radiation which are injected into reflector 100 while forming an angle of approximately -25° relative to the normal to the light radiation emission surface of source L, i.e. in a direction which forms, relative to axis X100, an angle ⁇ practically amounting to zero.
  • the components of the light radiation are subjected to a twofold reflection, initially on first surface 102a and from this on second surface 102b. Also in this case, the action of reflector 100 is such that most rays exit window 106 in an off-axis condition.
  • Figure 13 exemplifies the possibility, e.g. for components (rays) emitted from source L at an angle of about -65° to the normal to the light radiation emission surface (i.e. at an angle ⁇ relative to axis X100 of approximately -40°), of being subjected to a threefold reflection:
  • the light radiation pattern emitted by reflector 100 has been found to exhibit a side widening (FWHM amounting approximately to 100°) while showing a good degree of uniformity, albeit being emitted in a tilted direction relative to wall W, as previously exemplified.
  • One or more embodiments may therefore concern a reflector (e.g. 100) to produce a wall-washing lighting pattern from an electrically-powered light radiation source (e.g. L).
  • a reflector e.g. 100
  • an electrically-powered light radiation source e.g. L
  • a reflector may include a body traversed by a light propagation cavity (e.g. 102) defining a light propagation path between a light injection window (e.g. 104) lying in a first plane (e.g. X104) and a light emission window (e.g. 106) lying in a second plane (e.g. X106).
  • a light propagation cavity e.g. 102
  • a light injection window e.g. 104 lying in a first plane (e.g. X104) and a light emission window (e.g. 106) lying in a second plane (e.g. X106).
  • the light propagation cavity may have a flattened shape, with a first (e.g. 102a) and a second (e.g. 102b) light reflective surfaces lying in opposite planes relative to said light injection window.
  • the light emission window 106 may have two straight (rectilinear) edges connected by curved (concave/convex) edges, linked with the corresponding surface portions of light radiation propagation cavity 102 bordering on said edges.
  • said first plane may be tilted relative to said second plane.
  • said first plane may be tilted at approximately 25° (see e.g. the angle denoted as ⁇ in the Figures) relative to said second plane.
  • the fact that, in one or more embodiments, the (first) plane X104 (lying plane of source L) is tilted relative to the (second) plane X106 (lying plane of the light emission window 106) may also be described by stating that both such planes (X104 and X106) form an obtuse angle therebetween (e.g. of a width 180° - ⁇ ).
  • said first plane may be parallel to said second plane.
  • At least one of said first and second planes may be orthogonal to an axis of the reflector (e.g. X100), and said light propagation path may be tilted relative to said axis of the reflector.
  • the body of the reflector may include a light-impermeable material, so that said light injection window is not visible through said light emission window (e.g. viewed from the front, e.g. in the direction of said reflector axis).
  • One or more embodiments may include an intermediate screen (e.g. 100c) between said first and said second portion.
  • said intermediate screen may be chosen between a light-permeable screen and a light diffusive screen.
  • said first reflective surface may extend towards said light injection window, so that e.g. said first reflective surface is adapted to be impinged on by the light radiation injected into said light injection window in a direction orthogonal to said first plane.
  • said second reflective surface may extend away from said light injection window, so that said second reflective surface may be impinged on e.g.:
  • said first and second reflective portions may define a gap therebetween, enabling a direct reflectionless propagation of the light radiation from said light injection window to said light emission window.
  • a lighting device may comprise:
  • light radiation source L may be located outside the reflector.
  • a method of implementing a wall-washing lighting pattern of a wall may include:
