Definitions

  • the light was one or two in variable message signs multiple lamps by means of optical fibers on a variety of points of light, which become symbols or characters are arranged, divided and the change between the Display by switching the associated lamps on and off causes.
  • LED light-emitting diodes
  • LEDs differ from conventional light bulbs not only through the generation of light using semiconductor technology, which is an almost monochromatic colored light generated, but also by integrated optical measures for light control, which, on the one hand, determines the amount of useful light improve, on the other hand, universal, favorable light distribution characteristics in narrow and wide radiating versions generate so that the LED without further optical Measures can be used directly as signal light.
  • the LEDs are used directly without additional optical measures used, light color corresponds to Brightness and uniformity mostly meet the requirements,
  • the required light distribution is often only by means of a ballast additional lenses available, the main problem is that high phantom light.
  • the lens crest is usually crystal clear transparent LED body bundles incident sunlight directly on the highly reflective fixtures in the Inside of the LED, such as reflector and reflector edge, Connection flags and contact points from where it is is thrown back. Because of the crystal clear LED body also the phantom light is relatively whitish and unfiltered and often appears brighter than that when the sun is unfavorable actual signal light.
  • a known measure is to put a converging lens in a suitable distance in front of a relatively wide beam LED to set (Fig. 8).
  • the slanting sunlight becomes at a sufficient distance from the LED to the converging lens Entirely passed outside the LED and on the housing surfaces absorbed.
  • this arrangement has the disadvantage of one large space requirement and is therefore not suitable for universal application.
  • Another measure is to use the Signal color in colored lenses or LED bodies (tinting).
  • the sunlight has to pass through the colored component twice, especially the foreign color components of the light be filtered out, the LED light only once, the Coloring for the actual signal color as permeable as possible is.
  • the disadvantage is not only the lower useful light intensity, what by a higher number of light points must be compensated, but also the phantom light in Signal color which is compared to white phantom light is viewed as particularly critical in many applications.
  • Another disadvantage is the usually circular symmetry Light emission from the LEDs, which leads to that a large proportion of light is unused in irrelevant areas is emitted if not also optical measures against being taken.
  • the object of the invention is a universal LED optics to develop for variable message signs, which without Windscreen and with a smooth outer surface can and the advantages of LED, such as low energy consumption, long service life and freedom from maintenance benefits, on the other hand has almost no phantom light, which individually adjustable, especially oval light distributions enables to different without significant loss of light LED designs, LED suppliers or radiation characteristics is adaptable and the smallest possible center distance Adjacent optics allowed.
  • a light source preferably a light-emitting diode (LED)
  • at least one converging lens and one diverging lens from one common housing, essentially coaxial to geometric axis of the element are arranged, wherein the converging lens at every point of the diffusing lens facing surface emerging at an angle g divergent light beams as completely as possible on the Scattering lens bundles, whereby the scattering lens is designed that practically all light rays emerging from it are included Your inclination below a defined inclination angle ⁇ lie, and being the housing as a tubular Envelope of light source, collecting and scattering lens, on his Completely closed circumference and inside provided with a light-absorbing color and structure is.
  • LED light-emitting diode
  • FIGS. 1 to 7 show preferred embodiments in FIG Section, Fig. 8 and 9 previously common solutions in comparison.
  • Fig. 1 shows a vertical section through an inventive Optics.
  • the light source in all examples as an LED shown with a wide radiation pattern, sends its light 6 on the coaxially arranged immediately in front of it Collecting lens 2. This is on the one hand better light beam possible than by using a tight-knit LED, on the other hand, can affect the light beam become.
  • Internals 19 are shown within the LED 1. They are used for power supply and positioning of the actually luminous semiconductor chip 20, but form also an auxiliary reflector 21, which emits the side Reflected and have light in the main emission direction therefore high-gloss surfaces. That is why the LED works for optics in the immediate vicinity not as Spotlight, it sends a mixture of direct and reflected light rays. The light can only very poorly focused, which is why for the lens geometries also no physically exact information given can only be qualitative descriptions of their Characteristics.
  • Step at any point on the surface of the converging lens 2 Beams of light 7, whose divergence S ⁇ by Art and size of all internals 19, 20 and 21 is conditional and for each position of the converging lens 2 must be determined specifically.
  • the geometry of the converging lens is therefore preferably in iterative calculations. Be favorably the light beams 7 deflected so that as many as possible of their light rays fall through the scattering lens 3, which arranged coaxially to the converging lens at a certain distance is. There, the light beams 7 are deflected or scattered that the desired light distribution 8 is achieved.
  • the angle ⁇ gives the light incidence limit for stray light, especially the light of the low-lying sun 12, which should not yet generate phantom light.
  • the regulations go from a position of the sun of 10 degrees vertically above the Reference axis (usually the direction of the highest useful light intensity) out. Because of inevitable tolerances and the Size of the sun diameter itself is recommended Setting this inclination angle ⁇ to about 9 degrees, es any other angle can also be chosen become.
  • the size of the angle ⁇ determines the entire geometry of the optics.
  • the geometry of the lens 3 is set so that the emerging light rays 8 with their inclinations ⁇ always stay below the inclination angle ⁇ . Hiefuch will ensures that even in the reverse direction no Sunbeam 12 if it is at an angle g greater / equal ⁇ meets the optics, the same way back either via the reflector 21 or directly to Chip 20 of LED 1 is found and the LED lights up simulated. Nevertheless, light rays 22 up to the LED 1 penetrate. You meet others, not immediately surfaces 23 involved in the light radiation, or often reflected several times on the vitreous of the LED and broken and also produce a in this way too certain phantom light.
  • the length of the optics is therefore preferred set so that no sunbeam at all 12, which has an angle of incidence g greater or equal has the angle of inclination ⁇ up to the converging lens 2 or LED 1 can penetrate.
  • This is the case inside with the most matt, light-absorbing Surface structure, e.g. Circumferential grooves and preferred executed in black, so that there are all incident light rays 12 can absorb as well as possible.
  • the housing 4 is completely closed on the circumference, on the one hand, to be able to absorb light anywhere on the other hand, to allow light exchange within the device prevent, but also to prevent lens contamination prevent.
  • the optics are fastened in a matrix plate 24.
  • the Dimensions of the components are not much larger in the Diameter than the LED itself, so there is a corresponding tight arrangement possible. When accepting certain The diameter can also lose more light be reduced.
  • Fig. 2 shows a design that is generally smaller Has length than in Fig. 1.
  • the divergent Beams of light 7 cross each other before hitting onto the scattering lens 3 and there form a focal spot 9.
  • the converging lens 2 needs a higher light refraction than in the previous example.
  • the desired light distribution 8 and the resulting refractive power of the scattering lens 3 there is also the possibility that all sun rays 12 having an angle of incidence g greater than / equal to that Have inclination angle ⁇ , absorbed on the housing wall become.
  • the focal spot 9 also creates a space between Housing wall and useful light rays, which either through a constriction of the housing 4 at this point, better but by installing at least one aperture 10 that Phatom light behavior can significantly improve.
  • FIG. 3 shows an aperture 10 in the area of the focal spot 9, whose opening 11 to the circumference of the light beam 7 is adjusted. It keeps sun rays 12 from penetrating further completely into the interior of the housing.
  • Fig. 4 shows such an optics in elevation and plan.
  • the Scattering lens 3 has a focal point 14 in the area of Focal spot 9, where there is also an aperture 10.
  • the distance to the lens 3 and the aperture size is so chosen that the focal point of sun rays 12, which are parallel with the inclination of the inclination angle ⁇ , is within the aperture 10 or just behind. This means that no sunbeam can penetrate further into the interior.
  • the formation of the diverging lens with focus 14 has Consequence that the light distribution 8 according to the optical imaging laws an upside down image of the aperture 11 and the light distribution prevailing there and intensity results.
  • the determination of the light distribution In this case, the appropriate detail design of the Collecting lens 2 take place by the light beam 7 be pivoted more or less. At most kick increased losses due to edge light rays 13 at the aperture 10, or useful light rays no longer striking the scattering lens 3 on.
  • Fig. 4 further shows that the focal point 14 only in vertical Direction is required.
  • the floor plan shows that with the help of the vertical scatter optics 15 on the inside the scattering lens 3 a horizontal spread of the emitted Light 8 takes place so that a total of any oval light distribution can be achieved.
  • FIG. 5 shows the deflection of the light distribution 8 by one Angle e, which is defined by a horizontal lens structure 16 is effected. This will increase visibility in those cases improved in which the display device is not oblique can be tilted downwards. At the same angle e phantom light sensitivity also improves because also the sun rays 12 down by this amount be directed against the aperture 10.
  • Fig. 6 shows an oval design in addition to the round shape for optics with horizontal axis of symmetry, in particular also oval-radiating optics, as well as an egg-shaped design with only one positioning option.
  • the housing 4 can also be split, making the bezel light can be integrated.
  • the subdivision allows in particular the construction of a modular system with different Light distributions and manufacturer-specific LED designs.
  • Fig. 7 shows such a modular system optical, mechanical and electrical interfaces represents.
  • the rear housing contains each Converging lens and the LED. While the front housing 4 velvet Aperture 10 is the same here, the rear housing varies by LED type. Because each LED design has its own radiation pattern must also have the converging lens be customized. If every LED type in focal spot 9 has approximately the same light distribution they can be combined with different lenses 3 become. These can have the same outer facade, the different spreading structures are on the Inside. An LED 1a in SMD technology is shown above, which practically always soldered onto a circuit board is. So all LED 1a can on a common board 17a, which is also the wiring and power supply includes, be attached.
  • circuit board 17a after soldering on extensions 18a of the associated housing 4a snapped so that the optics are all one below the other be supported and aligned. Even the mix with other types of LEDs are possible; 4b in the circuit board 17a. Below is an LED 1b shown in standard design ⁇ 3 or ⁇ 5 mm. This can either also be soldered onto a circuit board 17b, for this exact extensions 18b are on Housing 4b attached. But it can also be freely wired be what is especially with small quantities and individually built devices recommended.
  • Moving housing parts against each other and so the look to adjust.
  • snap grooves or the like may be attached at the contact points 25 Thread. All Optics are attached in a common matrix plate 24 and have the same appearance for the viewer.
  • different front housings can also be used 4 with different apertures 10.
  • all representations also with colored lenses or Light sources run what that through the lenses self-generated reflex phantom light reduced.
  • Both collecting line 2 as well as scattering lens 3 can also be used as a Fresnel lens be executed.
  • LED or light sources are only exemplary. The rapid development in this area constantly creates new designs and functional principles, what ongoing adaptations of housing 4 and converging lens 2 require. Of course, any can other light sources are used.
