Definitions
- the invention relates to light signal, a light signal, in particular for rail-bound traffic routes, with a light source and egg ⁇ nem optical system for signal term visualization, particularly in a remote area, and a close range with respect to this bent.
- light signals are used as a signal generator or symbol ⁇ scoreboard, by color and / or forming a light-emitting surface, that is, by the radiation, convey certain information. These are often safety-relevant information that must not be falsified visually or blended by extraneous light.
- the undesired lighting up or falsification of a light spot by the incidence of ambient light, for example solar radiation or headlight, is called a phantom effect.
- the phantom effect it can in extreme cases ⁇ look incorrect as a result of ill-timed lighting of a light spot or a color shift coming. Particularly disturbing occurs this effect in the Verwen ⁇ tion of LED arrays as a light source, since LEDs can be excited by incident light to shine or in LED light sources often rear reflectors are used.
- Light exit surfaces of a cover glass and the optical system such as a Fresnel lens, and on compo ⁇ len in the region of the light source.
- a cover glass and the optical system such as a Fresnel lens
- compo ⁇ len in the region of the light source.
- Figure 1 shows the reflection ratios to be improved which are caused by internal fittings 1 and a lens 2 of a Lichtsig ⁇ Nals. It is evident that obliquely incident on the lens 2 at the top 3 sunlight reflected on the externa ⁇ ßerer and inner surface 4 and 5 are partially obliquely downward 6 and 7.
- the lens 2 soudrin ⁇ ing sunlight 3 can at the internals 1 within a Signal housing 8 are reflected at an unfavorable angle as a disturbing phantom light obliquely down 9.
- the re ⁇ flexed ghost light 6, 7 and 9 superposed on the to be visualized by a light source 10 of information.
- the all construction parts enclosing housing 8 also serves to at least ei ⁇ NEN part of the sunlight 3, both inside and au ⁇ infomon shield. Usually, a further portion of the sunlight 3 is shielded by a barge, not shown here, covering the lens 2 in the upper area.
- barges have the disadvantage that a high wind load arises, which must be compensated by a correspondingly stable signal mast construction. Through snow on the barge further signals can be covered. Besides the ⁇ is by barge, which significantly surpasses the light-emitting surface of the signal often prevents the application itself ⁇ cleaning light-emitting surface coatings that solar radiation and require irrigation.
- the invention has for its object to provide a light signal of the generic type, in which a deterioration of safety and significant loss of light due to the Phantom effect are largely avoidable, it being desirable that barges and / or end glasses are unnecessary.
- the object is achieved in that the optical system comprises a Fresnel lens, the Lichtein ⁇ tread surface Fresnel structures and the Lichtaus ⁇ is stepped surface formed such that each tangent of the light exit surface with respect to an optical axis of the op ⁇ tables system an angle of> 105 °.
- the Fresnel structures are provided on the light entry surface and thus on the inner surface and not, as usual, on the outer surface of the Fresnel lens, the light exit surface ⁇ can be smooth and virtually formed without corrugations. This smooth and thus less sensitive surface causes a cover glass is no longer neces sary ⁇ .
- the inventive design of the Fresnel lens is sufficiently phantom to dispense with a barge as additional phantom protection can. This results in cost advantages.
- a funnel-shaped aperture is integrally ⁇ arranged between the light source and the optical system. This additional measure improves the phantom contactor if internal installations can lead to light phantoms next to or near the light source.
- the narrow opening of the funnel-shaped aperture is adapted to the light exit surface of the light source, while the wide opening of the funnel-shaped aperture corresponds to the aperture of the optical system.
- FIG. 1 shows a simplified illustration of interfering phantom light reflections
- FIG. 2 phantom light reduction in the interior of the signal
- FIG. 3 phantom light reduction by shaping according to the invention of a Fresnel lens
- Figure 4 shows the Fresnel lens according to Figure 3 in side view
- FIG. Figure 2 illustrates one way to reduce by the A ⁇ built 1 caused ghost light.
- a funnel-shaped aperture 11 is provided.
- the funnel-ge diaphragm 11 encloses with its narrow opening, the light source 10 and ⁇ widens up to the edge region of the hold ⁇ ren surface 5 of the lens 2.
- the fittings 1 can not cause any ghost light 9 more.
- the sunlight 3 impinges on the inner surface of the funnel-shaped aperture 11, where it is absorbed in part and multiple reflectors ⁇ advantage, so can result 12 extremely low light intensity only outwardly reflected light which only partially interfere as ghost light, while the largest Share is radiated in non-relevant solid angle.
- Figure 3 shows another way to effectively reduce the phantom effect. Shown is the cross-section of a thin disk of a Fresnel lens 13 in the region of an optical axis 14.
- the Fresnel lens 13 is formed with the Fresnel structures 15 at the light entrance surface and a light exit surface glat ⁇ th 16th In this case, an angle between the Tan ⁇ gente 17 at this point and the optical axis 14 of 90 ° + is provided for all Punk ⁇ te the light exit surface 16, wherein ⁇ 15 °.
- Figure 4 shows a side view and Figure 5 is a Perspecti ⁇ vische view of the Fresnel lens 13. Due to the very out. The ⁇ chen ghost light reductions this special shape of the Fresnel lens 13 to turn in particular at the same time encryption is the funnel-shaped diaphragm 11, it is possible to dispense with the usual Schuten-roofing of the Fresnel lens 13. Also, a cover glass is not required because of the smooth outer surface 16 of the Fresnel lens 13. The outer surface surface 16 may be formed virtually self-cleaning by special coating, as for the cleaning effect, it ⁇ ford variable rain exposure of the outer surface is prevented not by a barge.
