Definitions

  • the present invention is related, in a first aspect, to a lighting fixture for illumination of outside public areas, comprising one or more light emitting diode and corresponding refractive optical elements to guide the emitted light to one or more illumination areas.
  • a second aspect of the invention relates to a street lamp comprising the lighting fixture of the first aspect attached to a post.
  • LEDs light emitting diodes
  • lighting fixtures for illumination of outside public areas, such as streets, which comprise at least one fixed light emitting diode (LED) in a carrier and one refractive optical element per LED, such as a lens, to guide the emitted light to an illumination area on an illumination surface.
  • LED light emitting diode
  • Some proposals apply lenses in front of the LEDs, but then comprise a separate translucent bottom plate or cover, to protect the LEDs against environmental influences such as dirt and moisture, nut which must be also be passed by the light emitted by LEDs, being the consequence of using said separate elements (bottom plate and lenses) that the cost increases, while double losses occur as the LEDs' emitted light also pass through both elements.
  • JP2005116182 concerns to an illumination lighting fixture forming an enclosure, or insulating case, housing a circuit board with a plurality of LEDs, and also a bottom plate with through openings, through which LEDs emit light.
  • denominated “lens fixing means” On the external face of said bottom plate, denominated “lens fixing means", there is fixed a plurality of bulk lenses, each covering one of the through openings.
  • Sad bulk lenses have an inner well-shaped recessed part into which a part of one respective LED enters.
  • the LEDS described in JP2005116182 have flat faces which, when introduced into said bulk lenses, stay perpendicular to the optical axis direction of the lenses, and act as light outgoing faces.
  • the purpose of the present invention is to provide an alternative to the conventional lighting fixtures, which provides a better performance relating to, mainly, their optical arrangements, easier assembly, immunity against environmental influences, and heat sinking.
  • the present invention concerns, in a first aspect, to a lighting fixture for illumination of outside public areas, of the type which comprises:
  • each of the refractive optical elements is fixed to the internal face of the bottom plate through the periphery of one of said through openings.
  • each of said openings has a stepped edge through its periphery, embracing the internal face of the bottom plate, and at least one refractive optical element is fitted and retained sideways in said stepped edge.
  • the proposed lighting fixture comprises at least one sea (for instance made of synthetic material or glass), per opening, fitted between each refractive optical element and each stepped edge, around its whole periphery, for sealing the interior of said enclosure from said environmental influences.
  • sea for instance made of synthetic material or glass
  • the bottom plate of the lighting fixture proposed has a plurality of through openings distributed there along, such as according to a regular pattern, with their corresponding stepped edges and seals, and said lighting fixture comprises a plurality of LEDs, at least one per opening.
  • refractive optical elements such as lenses
  • bottom plate The fact that refractive optical elements, such as lenses, are fixed to the inner face of bottom plate, provides a pleasing appearance on one hand, while assembly is made easier on the other hand.
  • the lighting fixture proposed by the first aspect of the invention has, for a preferred embodiment a flattened shape, where said refractive optical elements are flattened lenses, and said bottom plate is arranged substantially parallel to the circuit board.
  • the lighting fixture comprise a group of at least two LEDs with respective refractive optical elements, whereby each combination of LED and reflective optical element that belongs to the group are arranged to illuminate mainly the same illumination area on an illumination surface.
  • each combination of LED and reflective optical element that belongs to the group are arranged to illuminate mainly the same illumination area on an illumination surface.
  • the light output of each LED in the group contributes to the light intensity of the illuminated area.
  • the generated illumination areas of each of these combinations only coincides for the most part because they are being generated by combinations situated in close proximity to each other.
  • LEDs belonging to a group be fixed on the same surface.
  • the refractive optical elements belonging to the group are joined with the referred inner face of the bottom plate, extending out parallel to the surface of the carrier. In fact this facilitates the LEDs and the optical elements to be as parallel to each other as reasonably possible, so that their combined generated beams are also parallel.
  • the lighting fixture proposed by the invention comprises two or more refractive elements integrated into a multistage optical element covering one of said openings, in front of at least two LEDs.
  • the assembly of the fixture is further simplified when the group of refractive elements belonging together between the bottom plate and the carrier includes the group of LEDs that also belong together.
  • each of the combinations of LEDs and refractive elements in the group are arranged to illuminate an oblong illuminated area, for instance when illuminating streets.
  • the illuminated area itself will mainly stretch out along the longitudinal direction of the street.
  • they are arranged to illuminate an asymmetrical illuminated area.
  • Lighting fixtures for illuminating streets are often placed on the edge of a sidewalk or its fixtures are fastened to a building. In such applications it would be desirable if the fixture could be placed off-centre while still providing excellent illumination on the road and sidewalk.
  • Optical losses in the optical refractive element occur, partly as result of reflection.
  • at least one of the active optical surfaces of a refractive element be covered with an anti-reflective coating. It is therefore feasible that this coating be applied to the inner side, the external side, or on both sides. The advantage of coating the inner side is that it would be better protected.
  • a phosphorus layer means in this case a material, which under the influence of light, emits light at a different wave length to that of its incoming light.
  • the light output is improved when a reflector, preferably a small one, is applied by being moulded around the conical collar of the LED.
  • the assembly of the fixture is simplified when more than one optical refractive element belonging to a group are joined to form a single component.
  • the lighting fixture of the invention provides some combinations of LEDs and optical refractive elements arranged solely to illuminate these edge areas.
  • the fixture includes an amount of secondary combinations of LEDs and optical refractive elements which do not belong to the main group, arranged for the illumination of a divergent illuminated area.
  • At least some of the combinations of LEDs and optical elements not belonging to the secondary group to be arranged for illuminating the secondary illuminated area, forming part of the illuminated area. In this way, the areas around the edge of the illuminated area can be illuminated better. This does not rule out the secondary illuminated area itself from extending outside the illuminated area.
  • the LEDs' carrier is manufactured from suitable thermal conducting material and then contacts (preferably by means of a large contact surface), at its edges, the fixture's enclosure in order to transfer the heat from the LEDs, and other possible components, to at least said cover, which is also made of a good thermal conducting material, for acting as a heat sink.
  • the carrier be moulded to form part of the enclosure. It is worth mentioning that these carriers are produced as printed circuit boards in many cases. The surface on which the components are being placed needs to be manufactured from an electrical insulator type of material so that functional conductive tracks can be laid down thereon. This essential measure is combined with that of the present embodiment by a so-called 'metal core' printed circuit board. It will soon be clear that other printed circuit boards, completely manufactured from electrically isolated material, could be applied as well.
  • a clean cooling surface is important.
  • the enclosure be designed with at smooth or partially smooth surface. It will soon be clear that the design of a smooth cooling surface ought to be applied to the fixtures that are equipped with LEDs as light sources; this measure also needs to apply to fixtures for different light sources such as vapour lamps.
  • the proposed lighting fixture comprises coupling means (such as a hinge and a fitting) for removably coupling its cover and bottom plate in a sealed manner.
  • coupling means such as a hinge and a fitting
  • a second aspect of the invention relates to a streetlight comprising the lighting provided by the first aspect, attached to a lamppost, with said cover and said bottom plate staying parallel or inclined with respect to the area to be illuminated.
  • the fixture shown in Figure 1 is attached to a lamppost 3 by means of a bar 2.
  • the fixture 1 comprises a bottom plate 4, which is furnished with a regular pattern of openings.
  • an optical refraction element 6 is fitted in each of the openings 5 in each of the openings 5 .
  • These openings 5 each have a stepped edge 7 in which the optical elements 6 are retained sideways.
  • a seal 8 is fitted in-between each of the optical elements 6 and the stepped edge 7 .
  • the embodiment shown here comprises a flat fixture that extends horizontally. However, it is also possible that a similar fixture could extend at a slight angle.
  • the bottom plate 4 of the fixture has a raised edge, inside which a printed circuit board 10 is placed, with the LEDs 11 situated on the underside thereof.
  • components 12 such as driver circuitry are mounted to ensure the LEDs 11 are being supplied with the correct current and voltage.
  • the components 12 could also be mounted onto the underside of the printed circuit board 10. It is also possible to utilize circuitry that is not mounted onto a printed circuit board 10 for the purpose of driving the LEDs 11. Hereby the printed circuit board 10 is retained between the raised edges 9.
  • the placement of the LEDs 11 on the printed circuit board 10 are such that the LEDs 11 are mounted precisely above the void created by the optical elements 6.
  • the fixture 1 comprises a cover 13 which is connected to the edge 9 by means of a hinge 14, opposite which a fitting 15 is situated for the purpose of sealing of the inside of the fixture. Naturally, packing can be used.
  • cover 13 is smooth. This result in possible contamination such as bird excrement being washed away more easily when it rains, so that the cooling surface is better maintained than would have been the case with the usual cooling fins. Such cooling fins would build up grime quickly, while rain scarcely has the potential to clean it off.
  • the printed circuit board 10 is fitted with a metal core, preferably made from aluminium, for efficient conducting of heat produced by the LEDs 11 and the components 12 towards the edge of the printed circuit board 10, where the heat can be transferred to the cover 13, is similar to the rest of the fixture and is preferably also made of a metal such as aluminium.
  • the bottom plate 4 also serves as a heat sink; given its large surface area, which is likewise smoothly finished and also exposed to the ambient conditions. It stands to reason that a fixture which is mounted at a slant still benefits from this cooling feature where the slanted surfaces lead to even better cleaning by the rain. This measure can also be realized in other configurations, such as with other shapes of the carrier 10 or when the carrier 10 extends at various angles.
  • FIG. 2 shows an optical refraction element 6, i.e. a lens, in more detail. From this drawing it is apparent that there is a void 20 in optical element 6 in which the corresponding LED 11 extends at least partially. On the one hand this void forms a surface with a refractive function, and on the other hand it encloses part of the LED 11, whereby a large part of the light emitted by the LED 11 is collected by the optical element 6 and being utilized effectively.
  • Figure 5 also shows the same parts, but here a collar-shaped reflector 23 is fitted around LED 11. Because of this the light output of LED 11 is utilized even more effectively.
  • Figure 6 shows a multistage optical element 24 which performs the function of three integrated independent optical elements, simplifying assembly and reducing the number of parts.
