Abstract

The unit (1) has a light source i.e. high performance color LED, for coupling light in a volume of luminescent screens (7) that are illuminated in prescribed visibility angles (alpha1, alpha2). The screens comprise an edge side (8), where the light source is aligned on the edge side of the screen. The volume of the screens comprises light-scattering nanoparticles (9) that allow illumination of the screens in a light-scattering manner. The screen is arranged within a headlight casing, and headlight glass is made of transparent light conductor material. The screens function as optical filters.

Description

  • A daytime running light unit for a vehicle will be described. The daytime running light unit has an outer contour, which is adapted to a front-side outer contour of the vehicle. A light source couples light into a volume of the daytime running light unit. A luminescent screen is arranged to illuminate at prescribed visibility angles of a daytime running light unit.
  • Such daytime running light units now belong to the signal lights of a vehicle, which also increasingly consume energy with increasing number per vehicle, which has a negative effect on fuel consumption. In addition, the tendency in signal light construction is to integrate the signal lights as large-scale design elements in the outer contour of the vehicle, which may be associated with the disadvantage that the energy consumption per vehicle continues to increase.
  • From the publication DE 10 2006 032 373 A1 is a luminaire arrangement for a motor vehicle headlamp with at least one in an on state light emitting light source known. The light can be coupled into a transparent light guide element. The light guide element comprises light-emitting effective light exit surfaces and separate non-lighting effective design surfaces. This light assembly can be used in particular as a signal light or as daytime driving or parking light. One disadvantage is that optically effective surface structures are to be impressed or introduced both in the edge-side light coupling region and in the region of the coupling-out surfaces, so that on the one hand a relatively thick transparent light guide body is required to realize the optical edge and surface structures and smooth surfaces of the light assembly for a Coupling and a decoupling of light are ineffective. Thus, an adaptation of such lighting arrangements to a smooth outer contour of a vehicle is not achievable.
  • Based on this prior art, it is an object to provide a daytime running light unit for a vehicle that is easily adaptable over a large area to a smooth outer contour of a vehicle.
  • This object is achieved with the subject matter of independent claim 1. Advantageous developments emerge from the dependent claims.
  • An embodiment of the invention relates to a daytime running light unit for a vehicle. The daytime running light unit has an outer contour. A light source couples light into a volume of the daytime running light unit. A luminescent screen is arranged to illuminate at prescribed visibility angles. The luminescent screen has at least one edge side, on which the light source is aligned. The volume of the luminescent screen contains light-scattering nanoparticles that light up the luminescent screen.
  • An advantage of this daytime running light unit is that the luminescent screen has a smooth upper side and a smooth rear side as well as smooth edge sides, which have neither an optical structure nor a rough or milky surface and practically transparent and clear as a luminescent screen of an optical material such as a PMMA plastic plate (Polymethylmethacryl) or a PMMA plastic body can be produced. This material is deformable and can be adapted to any curvature of the outer contour in the front region of a vehicle.
  • In this context, light-scattering nanoparticles are understood as meaning particles having a diameter of 10 to 200 nanometers which isotropically scatter the incident light of an exterior handle illumination unit, for which purpose colorless particles having a refractive index which differs from the optical waveguide material by 0.06 ≦ Δn ≦ 0 , 4 differs. The light-scattering nanoparticles may additionally be surrounded by a cladding layer which serves to embed them in the optical waveguide material. The embedding of the light-scattering nanoparticles results in a light guide material that is largely transparent in the unlit state, while it shows an effective all-round light emission at a light coupling, for example via an edge surface. Thus, with this material relatively robust handle or Griffmuscheln can be realized, which can be brought to light for the different functions using the exterior handle lighting unit.
  • In one embodiment of the invention, the daytime running light units' luminescent screens simultaneously form the outer sheaths of the daytime running light units and are located in front curved areas of the front fenders and are located adjacent to the front headlight positions. In this area, the curvature of the fenders can support compliance with the given front visibility angle of at least plus-minus 20 ° front with respect to the direction of travel. In this case, the fluorescent screen of the daytime running light unit can simultaneously form an outer shell and be arranged in a front lateral curvature region of the front fender adjacent to the front headlight positions.
  • Furthermore, it is possible for the fluorescent screen of the daytime running light unit to be arranged within a headlight housing behind a lateral curvature of a headlight glazing protecting the fluorescent screen. This makes it possible to provide an integrated optical block with headlamp and daytime running light unit, which is formed more compact and space-saving, as in the prior art known in the upper document.
  • In a further embodiment of the invention, the headlight glazing has a transparent light conductor material which has light-scattering nanoparticles in a partial area in the volume. This subregion of the headlight glazing, which has light-scattering nanoparticles in its volume, may be delimited to an area of the daytime running light screen, while the at least one light source is arranged on one of the edge sides of the headlight glazing or embedded in the headlight glazing of optical fiber material.
  • Thus, the headlamp glazing may form the daytime running light unit's luminescent screen and may be formed in a front curvature region so as to satisfy the visibility conditions of the visibility lights for the daytime running light unit. Thus, it is possible that the need for room depth of the daytime running light unit remains limited to the thickness of the headlight glazing.
  • In order to enhance the light-scattering effect of the nanoparticles, it is provided that the luminescent screen has a mirroring layer on its rear side. By means of this mirroring layer, all scattered light components which are scattered towards the rear side of the luminescent screen by the light-scattering nanoparticles are reflected toward an outer side of the luminescent screen. Instead of a mirroring layer, the rear side of the luminescent screen may also have a reflector foil.
  • Furthermore, it is possible for the light source to have a light-emitting diode whose thickness corresponds to the thickness of the luminescent screen and which is surrounded by mirror surfaces, so that its emitted light radiation is concentrated on one of the edge sides of the luminescent screen. If the light source is embedded in the luminescent screen, then at least one edge region in which the light source is integrated can have a mirroring layer on its surfaces in order to avoid a dazzling effect emanating from a light source and to reduce the irradiation effect of the daytime running light unit to that in the volume of the light source Fluorescent screen distributed to improve light-scattering nanoparticles.
  • It is particularly advantageous if the daytime running light unit has at least one white light source with at least one light-emitting high-performance light-emitting diode. In addition to stylistic and technological motives, such high-performance light-emitting diodes convince compared to conventional light sources by brighter light with color temperatures up to 4000 K, low energy consumption, dispensability of lamp changes due to the extremely high life of light emitting diodes as well as minimal device dimensions and a free programmability of the light distribution.
  • Furthermore, it is provided that the luminescent screen on its upper side has a partially transparent coating, which in an unlit state, ie. H. if the daytime running light unit is not switched on, has a metallic luster, the daylight and third-party headlight reflected shiny metallic. It is also possible for the daytime running light unit to provide additional light sources with different colors. Due to the color-emitting and switchable light-emitting diodes, the screen of the daytime running light unit can additionally light up for one or more of the following functions, such as flashing light function, position light function, parking light function and / or blue light function.
  • In difficult space conditions, it may be advantageous to arrange one or more optical fibers between the light source and the light coupling in the edge side of the screen, which focus the light of the light source on the edge side of the screen. For this application, optical fibers with a gradual increase in the refractive index to the outer jacket of the optical fiber out of advantage, since the relatively wide opening angle of a light emitting diode can be concentrated on the relatively narrow edge side of the light screen. The question as to whether a light-emitting diode is arranged directly on the edge surface of the luminescent screen or whether additionally a light transmission with the aid of a light guide also depends on the structural conditions of the daytime running light unit.
  • In a further embodiment of the invention, the light-scattering nanoparticles are arranged homogeneously in the volume of the luminescent screen, which even out the light scattering. In addition, it is envisaged to equip a vehicle with daytime running light units, which has the advantage that an approaching vehicle is better perceived by the preceding traffic and by other road users, such as pedestrians and cyclists. Also finding the parked vehicle is facilitated.

These conditions are in the illustrated arrangement of the screen 4 Fulfills.
  • 2 shows a schematic perspective view of a vehicle 2 with a daytime running light unit 10 according to a second embodiment of the invention. The daytime running light units 10 are different from the ones in 1 shown daytime running light units in that their fluorescent screens 7 integral part of headlamp covers of the headlamps 13 and 14 in the area of the fenders 11 and 12 of the vehicle 2 are.

  • 4 shows a schematic partially cross-sectional view through the daytime running light unit 10 according to 3 , Components having the same functions as in the previous figures are identified by the same reference numerals and will not be discussed separately. This cross-sectional view exemplifies an arrangement of light sources 5 in the form of high-performance light-emitting diodes 27 , the intense rays of light in the volume 6 to the contour of the pane glazing 17 adapted screen 7 over border sides 8th couple and an intense stray light on the nanoparticles 9 cause so that the luminescent screen 7 large area as daytime running light unit 10 lights. In addition to the high-performance diodes 27 also colored diodes can be provided to the luminous body 7 to light up as a direction indicator or as a position light or as a parking light. In addition, it is also possible that the fluorescent screen 7 from an intense, blue glowing high-performance light-emitting diode 27 is irradiated as a blue light and thus serves as a signal light for special vehicles.

Also, on the top 22 additionally a partially transparent coating 23 be arranged, the surface when not activated daytime running light 22 the daytime running light unit 10 appears as a shiny metallic surface. Also, this outer coating can 23 the top 22 of the screen 7 the daylight in different colors reflect, depending on the thickness of one on top 22 applied transparent layer.
  • 5 shows a schematic enlarged view of a daytime running light unit 20 according to a third embodiment in the field of headlight glazing 17 , For this purpose, the headlight glazing 17 itself be constructed of a light guide material and in the range of the daytime running light unit 20 light-scattering nanoparticles 9 exhibit. The difference to the previous examples is that a first screen area 25 and a second screen area 26 are provided, wherein the second phosphor screen area 26 an at least an order of magnitude higher concentration of light-scattering nanoparticles 9 has in its volume and is oriented such that its surface is arranged practically perpendicular to the direction of travel. When coupling light from high-performance light-emitting diodes, this second luminescent screen region becomes 26 clearly brighter than the first screen area 25 and thus the function of the brightly lit daytime running light unit 20 improve significantly.
  • 6 shows a schematic partially cross-sectional view through the daytime running light unit 20 according to 5 , The difference to that in 4 shown cross-section is that the light source 5 in the optical fiber material of the phosphor screen 7 is embedded and only electrical connections 28 on the edge sides 8th protrude from the screen material. While the back 19 of the screen 7 with a reflector foil 24 is the area of the light source 5 from a mirroring layer 21 surrounded to the coupling of light in the fluorescent screen 7 to reinforce.
  • Also in this case, the top can 22 a partially transparent layer 23 have that the top 22 of the screen 7 when the daytime running light unit is switched off 20 gives a metallic shine. On the other hand, it is also possible, this coating 23 made of a transparent material and to tune the thickness of the layer such that the top 22 of the screen 7 due to interference effects of daylight at the top 22 and the top of the coating appears colored.
