Definitions

  • the invention relates, in particular, to signaling optics for traffic signal systems, consisting of a preferably two-piece lens system with a condenser and a Scattering lens, as well as one at a fixed distance in the Region of the optical axis of the system arranged light source, consisting of a base plate with lighting elements.
  • Fiber optic technology can cause individual failures Points of light come through a break in the light guide.
  • Another disadvantage is the usually circular symmetry Light emission of the lighting elements, which are causes a large proportion of light to be wasted in irrelevant Areas is emitted.
  • LEDs have a predefined one Emission characteristics, usually with the prescribed Light distribution of the signal transmitter do not match. This often means disproportionately more pieces used just to be in faint areas yet to have enough light. Also in a fiber optic version can provide a light distribution that is precisely adapted to the requirements of the individual light points practically not or can only be achieved with disproportionate effort.
  • the aim of the invention is to take advantage of the LEDs, especially low power consumption and durability received, but to avoid the disadvantages mentioned above. It would also be an advantage if for cost reasons with fewer LEDs with unchanged lighting effect could get by.
  • the system should also be compatible Embodiments in fiber optic technology.
  • the lighting elements be arranged inside the signal chamber and such a substantially flat filament in place of form conventional incandescent lamps, even without a reflector emits a light directed directly towards the scattering lens, and its shape and size as well as the superior optics Beam characteristics or light distribution determined.
  • Fig. 1 shows the general system components in basic arrangement
  • Fig. 2 shows a variant of the light source in fiber optic technology
  • Fig. 3 represents one Section through a system with some light beam paths.
  • a Base plate 1 advantageously designed as a printed circuit board and more or less compact with lighting elements 2 equipped, the light throws on you preferably as a Fresnel lens trained condenser 3, which essentially has the dimensions of the scattering lens and the light in on is known to align itself as far as possible in parallel, or other cheap light collection.
  • the lens 4 then also provides with a large number of individual lenses 5 in known way for the scattering of light and the desired light distribution.
  • base plate 1 Replace base plate 1, lighting elements 2 and condenser 3 thus the previously common system incandescent lamp with reflector.
  • the base plate 1 is preferably seated in a plug 6, which you usually with a power supply 7th connects, so that it is simple and inexpensive in the event of a defect can be exchanged.
  • the lighting elements 2 preferably radiate their light within such an angle w that it from the condenser 3rd can be recorded as completely as possible. In this way are light components of each individual lighting element in almost each area of the condenser 3 is present and are by the individual lenses 5 of the lens 4 in the prescribed Scattered area XY. So is essentially in every direction of observation a certain amount of light from each one Each element appears to the viewer Luminous element 2 in a variety of individual lenses 5. By Superposition of all lighting elements 2 in the individual lenses 5 is no longer a recognition of a single light element possible and the appearance of the optics becomes even as until now.
  • a favorable design of the condenser 3 exists if the light beam bundling 11, which is between the condenser 3 and lens 4 arises at any point of the Condenser 3 as similar as possible in terms of their orientation, Intensity and light divergence is. This creates for the viewer a very evenly shining front lens.
  • the condenser 3 focuses the light in exactly the same way as a usual reflector.
  • the same Scattering lenses 4 as before, which are usually already on the prescribed light distributions are designed be used.
  • each individual cone of light w the condenser 3 is illuminated as precisely and completely as possible. This can be done by tilting or bending the base plate. This allows each light element the entire condenser area without significant loss illuminate.
  • the base plate 1 is doubled in size, for example, this results in the same lens configuration a correspondingly enlarged light distribution according to the laws of optics XY of the signal generator. Because optics, light distribution and arrangement of the lighting elements according to the optical laws related, one can at unchanged Optic components also meet the required light distribution suitable irregular assembly of the base plate with Achieve lighting elements. A system can thus be set up be that only a single condenser 3 and one Scattering lens 4 needed. Different light distributions and brightnesses are then differently equipped the base plate 1 achieved with lighting elements 2.
  • the light distribution will both by the action of the diverging lens 4, the condenser 3 as well as through appropriate distribution and arrangement of the Luminous elements 2 on the base plate 1, and their distance achieved to the optics.
  • symbols can be represented by templates, Painting the lens, etc.
  • Fig. 2 shows a light source
  • the lighting elements 2a are formed by ends of an optical fiber bundle 9.
  • Optics can be used.
  • the signal transmitter does not send light upwards at an angle
  • sunlight can also enter from diagonally above 10 do not fall on the lighting elements 2, so that they cannot produce phantom light. Since no more reflective surfaces are present, the arrangement is particularly low-phantom light.
  • the Base plate 1 with the lighting elements 2 positioned so that the bottom row of lighting elements in height the optical axis 8 is located.
  • XY a light distribution is obtained XY, which begins at the optical axis extends downward.
  • This favorable light distribution is already obtained by the condenser 3 alone again light losses upwards and reduced at the same time the phantom light hazard.
  • Such a design is also suitable for tightly bundled Signal transmitters, such as a railway signal.
  • the individual lighting elements form again as individual glowing points or light rays in the area from. The observer is between them Light rays, the signal appears dark.
  • This Effect can be countered by using the condenser 3 several suitable foci or trending Focal length is executed, so that no sharp image of the Luminous elements can arise.
  • Other options are Defocusing or minimal scattering through the scattering lens 4 that the light points are scattered only to the extent that they are sufficiently wide with neighboring points of light cover, so that a failure of individual lighting elements does not result in dark zones in the viewing area.
  • Another embodiment of the invention consists in the Equipping the base plate with different lighting elements, which also turned on at different times will. For example, red, yellow and green LEDs mixed, sit together on the base plate 1, the The signal generator can then selectively red, yellow or green Radiate light as well as mixed colors through simultaneous Switching on several types of light elements.
  • condenser 3 and lens 4 by superimposing the structurally to combine both optics, so that only one windscreen with correspondingly more complicated lenses becomes.
