Definitions

  • the invention relates to an optical element, which is usually used in an arbitrarily arranged plurality in substantially vertically arranged front surfaces of variable message signs for displaying symbols or graphic information, consisting of at least one controllable light source, usually an LED, which can sit on a board, a Lens element with light inlet surface, lateral surface and outlet surface and preferably a surrounding at least a portion of the lateral surface housing, with substantially horizontal to downward inclined light emission, wherein the lateral surface has a maximum light absorbing absorption surface.
  • Light-emitting diodes differ from conventional incandescent lamps not only by the generation of light by means of semiconductor technology, which produces a nearly monochromatic colored light, but also by integrated optical measures for directing light, which on the one hand improve the useful light component, on the other hand generate universal, favorable light distribution characteristics in narrow and broad-emitting versions, so that the LED can be used directly as a signal light without further optical measures.
  • the lens cap of the usually crystal clear transparent LED body focuses incident sunlight directly onto the highly reflective internals inside the LED, such as the reflector and reflector edge, terminal lugs and contact points, from where it is thrown back. Because of the crystal clear LED body and the phantom light is relatively whitish and unfiltered and may appear in unfavorable position of the sun may be brighter than the actual signal light.
  • Another measure is the use of colored in the signal color lenses or LED bodies.
  • the sunlight has to pass through the colored component twice, whereby above all the foreign color components of the light are filtered out, the LED light only once, whereby the coloring for the actual signal color is as permeable as possible.
  • the sunlight is significantly weakened, the useful light is reduced to a much lesser extent.
  • the disadvantage is not only the lower useful light intensity, which must be compensated by a higher number of points of light, but also the phantom light in signal color, which is considered to white phantom light in many applications as particularly critical.
  • Another disadvantage is the usually circularly symmetrical light emission of the LEDs, so that a large amount of light is emitted unused into irrelevant areas, if not also optical measures are taken against it.
  • commercially available light-emitting diodes have emission characteristics which generally do not agree well with the required light distribution of the light spots.
  • disproportionately more LEDs must be used without additional optics, only to have sufficient light in low-light areas.
  • the required light distribution can not be achieved at all without additional measures.
  • good devices consistently use conversion lenses that can achieve the desired distributions very effectively. At the same time, this also measures against phantom light be taken.
  • the light of an LED is focused by means of a converging lens either on a scattering lens or in particular on an aperture between collecting and scattering lens and directed by means of the scattering lens in the prescribed range.
  • Sunbeams are absorbed either on the housing wall or the aperture.
  • This design has the advantage that virtually no sunlight can reach the LED.
  • the LEDs can be individually wired or sit together on a circuit board. Furthermore, any arrangement of individual optics is possible. The optic diameter is relatively small.
  • a disadvantage is a variety of components, which affect the cost unfavorable and also an automatic production very difficult, but also the large number of interfaces, which must penetrate the light and thereby suffers loss of brightness, but in particular also generates the sunlight surface reflections at least on the one and exit surface of the dispersion lens before it is absorbed. This creates phantom light again, which impairs the recognizability.
  • the EP 1 227 458 A2 which is considered to be the closest prior art to the subject-matter of claim 1, discloses altogether a display and / or signaling device for light-optical information.
  • This device comprises a carrier plate or a housing part with light sources arranged thereon.
  • a lens body provided here is provided with a Lichtleitfortsatz, which is arranged in corresponding recesses of the support plate.
  • the surface on which rest the Lichtleitfort instruments provided with a light absorption layer.
  • a module is presented, which is made of transparent material and has integrated a plurality of similar scattered lenses, which direct the light of the LED, which sit on a common board in the observation area.
  • the inside of the module is light absorbing coated black except for the light entry surfaces, which are due to the saving of material on extensions, so that incident sun rays are absorbed.
  • This design has the economic advantage that it consists of only one component and a circuit board with LED.
  • the light penetrates only the entrance and exit surfaces of the module, which minimizes losses.
  • Sunlight from the outside only creates a surface reflection on the front surface, then it is already absorbed on the inside wall of the module.
  • a disadvantage is the fixed arrangement in a grid, which limits the use of graphic displays.
  • Each grid requires a separate module.
  • the transition surfaces between the lenses must be tilted so high up or down that no reflections can occur in the direction of observation, but this results in a highly fissured, particularly dirt-prone surface.
  • the absence of a metallic matrix plate only limited protection against electromagnetic interference or lightning is possible. Nevertheless, a supporting structure with a vertical sealing surface is necessary, to which the modules are attached.
  • the aim of the invention is an inexpensive optics for variable message signs, which meets the standardized light distribution and has the lowest possible phantom light. It should consist of as few components as possible and be fully automatic mountable. It should be able to be mounted tightly and precisely both in freely selectable arrangements and in any desired grids, preferably using a metallic matrix plate, and should have the highest possible packing density.
  • the EP 1 227 458 A2 The surface of the support plate is provided with their recesses with a light absorption layer. Since the lens body completely covers the light absorption layer with its wall regions, it does not adjoin the light exit surface at any point. Similar to an optical fiber, undesirable scattered light can pass via these wall regions to adjacent lens bodies where it produces undesired effects such as phantom images. In accordance with the present invention, this is excluded from the outset, and the attraction of the absorption layer from the light entrance surface to the light exit surface causes more extensive light absorption of any external light sources.

  • Fig. 4 preferred outlines of the mounting holes in view
  • FIGS. 5 and 6 show combinations of the optical element according to the invention in vertical section.
  • Fig. 1 the optical element according to the invention is shown in its simplest embodiment in vertical section.
  • a light source 2 in the form of an LED coaxial immediately behind a lens element 3 with a light entrance surface 4 and an exit surface 5, connected by a lateral surface 6.
  • the exact positioning of the board 1 with the LED takes place in any way outside the representation.
  • the lens element is mounted in a vertically arranged metallic matrix plate 7 and fixed and sealed with an adhesive 8.
  • the lateral surface 6 is coated black in the entire lower region between the light entry surface 4 and the exit surface 5, so that any incident light beam is absorbed. This area is referred to as absorption area 9.
  • the light beams 10 of the LED enter at the light entry surface 4, pass through the lens element 3 and exit at the exit surface 5.
  • the light entrance surface 4 acts as a converging lens, captures as much light as possible of the LED and concentrates it on the exit surface 5, from which it is directed with the required intensity and distribution into the prescribed observation region.
  • This range is expediently determined in such a way that the greatest intensity occurs in the horizontal axis direction and the side decreases more or less rapidly to zero, either downwards or downwards. Upwards, no light emission is required at all.
  • This radiation characteristic is achieved not only by the influence of the light source 2 and the light entrance surface 4, but above all by a suitable design of the exit surface 5 by means of different curvature zones, which will not be discussed in detail here. It can be seen, however, that the drawn light beams 10 are only horizontally and more or less directed downwards.
  • the curvature of the exit surface 5 is on each surface point is formed so that substantially all of the light beam 10 coming from the light source 2 in a range below a predetermined angle S, preferably less than or equal to 10 ° with respect to the horizontal and substantially all externally with an angle greater than or equal to S respect the horizontal incident light beams 11 are directed onto the absorption surface 9.
  • the incident light rays from the outside such as Sun rays 11 located, which reach at an angle to the horizontal angle S (vertical sun angle) parallel to each other on the exit surface 5. They penetrate into the lens element and are directed by the exit surface 5 on the absorption surface 9, where they are absorbed. Furthermore, a sun ray 11 a is drawn in, which is incident at a smaller vertical angle than S. It reaches the reflector of the LED, where it is reflected and scattered, creating the dreaded phantom light. But it is also a light beam 11b located, which is incident at a larger vertical angle than S. He reaches the absorption surface 9 accordingly earlier and is absorbed.
  • S vertical sun angle
  • the angle S set for the incident sunrays represents a vertical limit angle. In this position of the sun, no ray of sun 11 can just advance to the light source 2, it is destroyed at the absorption surface 9. It is immediately obvious that with every higher position of the sun, the sun's rays 11b hit the absorption surface earlier and no phantom light is produced. At a lower position of the sun, however, some of the sun's rays 11a penetrate into the light source 2 through the light entry surface 4 and produce phantom light.
  • the design of the exit surface 5 is not inconsistent with respect to the two different requirements, namely the light distribution of light rays 10 and the directing of sun rays 11 on the absorption surface 9, because the lens element 3 rotates in principle according to optical laws Appearance of the bright light entrance surface 4 with the black absorption area adjacent to the head, so that it is displayed as a brightly lit observation area with overlying dark zone. So it is emitted with the right orientation no light upwards.
  • any number of optical elements may be incorporated in the matrix plate 7 in any arrangement.
  • the light sources 2 then all preferably sit on the same board 1, which also has other electrical components for power supply and control and all interconnects.
  • Fig. 2 represents a modified optical element in vertical section.
  • the lateral surface is designed entirely as an absorption surface 9.
  • the black coating is made of plastic and is thickened to a solid envelope of the lens element 3, which now forms a housing 12.
  • the housing 12 In the region of the exit surface 5, the housing 12 has a flange 13 as a contact surface. Adjacent to the housing peripheral circumferential ribs 14 are mounted with sawtooth cross-section.
  • an exact receptacle 15 for the light source 2 is formed in the area of the light entry surface 4.
  • the light source 2 is not sitting here on a circuit board 1, but is directly wired and held by a mitformed to the housing 12 snap hook 16. Such a design saves the board costs for small quantities.
  • the illustration shows the optical element before being pressed in.
  • the ribs 14 have over the mounting hole 17 a slight excess. When pressed they are elastically / plastically deformed in a known manner, hold the optical element by frictional engagement in the mounting hole 17 and seal at the same time.
  • the flange 13 ensures the exact alignment by abutment against the matrix plate 7.
  • the housing material is much tougher and more resilient than the material of the lens element 3, so that during pressing only the ribs 14, but not the lens element 3 are deformed.
  • the optic element is longer here.
  • the sun's rays 11 have a greater path length in the lens element 3 up to the absorption surface 9.
  • the exit surface 5 is designed asymmetrically.
  • the upper portion is more curved, thereby deflecting overhead light rays 10c more downward, even the overhead sun rays 11c, which otherwise reach the first light entrance surface 4, are broken down more and reach the absorption surface 9 earlier. Through these two measures a total of a smaller sun angle S can be achieved.
  • the light region below the horizontal is therefore preferably illuminated by light rays 11 c from the upper region of the exit surface 5.
  • the black housing 12 and the lateral surface 6 of the lens element 3 must be optically effectively connected to each other, in particular by melting together. A mere mating of two individual components would not result in an absorption of the sun's rays 11, but their total reflection and thus considerable phantom light, despite identical graphic representation.
  • Fig. 3 shows this embodiment in connection with a particularly broad-emitting light source 2 in the form of an SMD LED.
  • SMD LEDs are inexpensive and particularly accurate to position on the board 1, however, only a portion of the light on the light entry surface 4 can be beneficially prebound.
  • Particularly far away exiting light beams 10d are therefore directed via a total reflection at the free area of the lateral surface 6 through the exit surface 5 in the light distribution area, where they because of the greater deflection to brighten the edge areas or of close range contribute. Inclination and curvature, or even optical surface structures, as well as a more complicated design of the lateral surface 6 are this freely selectable within reasonable geometric limits.
  • sun rays 11d can reach the totally reflecting surface 6, in particular when exposed to the side. However, they tend to be reflected downwardly to be subsequently absorbed on the absorbing surface 9. This is at least guaranteed if the lateral surface 6 is totally reflected only in the upper region.
  • the housing 12 has at the bottom of a bore 18, whereby the board 1 is positioned and held by a position hole 19 and screw 20.
  • this optical element Due to the wide light emission of the SMD LED, this optical element is shorter and conical than in Fig. 2 , In this case, it may be necessary to pull the absorption surface 9 so far toward the optical axis of the lens element 3 that already a part of the LED light is shaded.
  • cross-section AA it can be seen that the absorption surface 9 has been formed by flattening the lower region of the lens element 3, which is conical in itself. But it also extends a bit laterally to about the middle up. The flat region of the absorption surface 9 extends to the light entry surface 4, where it forms a horizontal edge 21.
  • connection edge 21 is an essential characteristic for the size of the angle of incidence S of the sun's rays.
  • Position and shape of the absorption surface 9 in the remaining region of the lateral surface 6 are of minor importance.
  • flattening may be helpful in orienting the optical elements in the mounting holes 17 or even in the manufacture of the components.
  • the sprue of the lens element 3 or of the housing 12 can take place.
  • the total reflecting zone of the lateral surface 6 should naturally be as large as possible to use as much light as possible, on the other hand, the absorption surface 9 must be present wherever solar rays 11 are absorbed on the lateral surface 6 have to. More precise determinations can be made by light beam tracking in a computer simulation.
  • Fig. 4 shows a selection of Einbaulöchem in the matrix plate with different properties.
  • a circular hole a allows any orientation of the optic element. Either it must be circularly symmetrical or be oriented by external measures.
  • the elliptical hole b allows attachment in two orientations. This is meaningful with appropriate symmetry of the optical element, but also with an easy recognizability of the orientation.
  • Clear orientation is achieved by a flattened or drop-shaped hole c or d.
  • the outline is oriented, for example, according to a flattened absorption surface 9 or the attachment hole 18 Fig. 3 ,
  • Fig. 5 shows a combination of optical elements of the same design, which are connected via a connecting surface 22 in any number, but preferably regular arrangement. They are pressed or glued together in the matrix plate 7. Each combination has at least one position pin 23, which projects through a matching position hole 19 of the common board 1 and this holds by means of commercially available fasteners, such as the lock washer 24 shown.
  • the front of the connection surface 22, like the housing 12, is black and has a maximum light-absorbing structure 25. As a result, the matrix plate 7 does not require a surface coating.
  • a module even without a matrix plate, is rigid in itself and usually has at its edges connecting means, such as the illustrated tongue and groove system 26, in order to be able to form arbitrarily large display panels by placing them in a known manner.
  • Another advantage is the significantly smaller distance between the lens elements relative to the embodiment in FIG Fig. 3 or 5 ,
  • the common board 1 is here by means of at least one snap hook 16 held per module and positioned by means of position pins 23 and position holes 19.
  • the black front of the housing block has a maximum light-absorbing structure 25.
  • the light source 2 consist of several individual light sources, which are arranged together behind a lens element 3. It can even be present for each individual light source, a specially designed light entry surface. This allows an effective achievement even of very specific light distribution, a higher amount of light per optical element or security in case of failure of an LED. In particular, this allows the emission of different colors with only one optical element, which reduces the cost or allows a higher image resolution.
  • special design of the lens element 3 can be achieved that the colors have approximately the same light distribution within a limited observation area.
