Description

Technical field

The invention relates to a rear light a vehicle that can be used as a direction indicator, fog lamp, Reversing light, Brake light, as well as parking light, and, if necessary, reflector is used after the Preamble of claim 1.

State of the art

A motor vehicle usually has on both sides at its top end as light emitting / reflecting Components each a yellow rear direction indicator, one glowing white fog lamp, a glowing white reversing light, a red brake light, and always at the same time with the headlights so-called "secondary light" switched on and off (which serves as parking light when parking and can serve as a warning signal when driving), as well as a retroreflective reflector on. Depending on the versions can these light-emitting components separately or side by side or one above the other each be arranged compacted on one side at the rear end of a vehicle to form a “rear light”. A requirement for the Arrangement of the light-emitting components is that they too a whole simple geometric figure (e.g. a rectangle, a trapezoid, etc.) can be put together. For light scattering the lenses of the respective light-emitting components e.g. prismatic or honeycomb-shaped Structuring provided. Light bulbs (such as halogen lamps) can be used as the light source. and LEDs (e.g. ultra bright or super bright LEDs) are used become. About that reflectors are also available Retroreflection of the light beams from the headlights of motor vehicles approaching behind the rear light arranged.

Despite the numerous arrangement options of the light-emitting / reflecting components of rear lights are they and thus their lenses either circular or Rectangular and therefore there is a lack of diversity in appearance. In other words, in every driving condition (working condition of the taillight, i.e. when cornering, when driving in a foggy environment, on a return trip, in the event of braking, short-term parking, etc.) only ever a crisis-shaped or see rectangular lighting regardless of whether this taillight with its direction indicator, its fog lamp, its glowing white reversing light, his brake light, his auxiliary light, or his parking light shines.

The invention is based on the object Taillight, where all the functions of the direction indicator, fog lamp, Reversing light, Brake light, and possibly auxiliary light, as well as reflectors in one Pack summarized are to be created, with which the aforementioned disadvantage is avoided can be made without losing the compact arrangement of this Having to buy components.

This task is done with a taillight according to the preamble of claim 1, optionally as a direction indicator, Fog lamp, reversing light, Brake light, as well as auxiliary light, and possibly reflectors, and that serves Light sources for the respective light-emitting components --- direction indicators, Fog lamp, reversing light, brake light, and secondary light ---, a ring-shaped honeycomb-like diffuser, and an opaque hood has, which, together with the lens, encloses an interior in which the light-emitting components and their corresponding light sources are included, according to the invention the characterizing features of claim 1 solved in that the lens divided into the following six optically isolated zones becomes: a surrounding annular peripheral zone and an X-shaped one central zone to which the light rays from the light source for the brake light or the secondary light, and four sectors, each by two legs of the X shape and an arcuate portion of the peripheral zone be limited, the light rays of the light source for the fog lamp on the upper sector, the light rays of the light source for the direction indicator to the left and right sectors, respectively, and the light beams the light source for the Reversing lights be directed to the lower sector.

This ensures that with a rear light according to the invention one in each case can see the following luminous forms: a luminous lying Eight (∞-shaped lighting) of the Direction indicator on the inside of a curve when cornering, one luminous sector with its tip pointing downwards (fog lamp) when driving in a foggy environment, a glowing, with its top upward facing sector (reversing lights) at one Return, an annular or a ⊕-shaped luminous form (brake or auxiliary light) when braking or parking.

An embodiment of the invention provides before that central X-shaped Zone as a reflector can be used. In this variant you can see an X-shaped retroreflection.

Because the six zones form a circular shape can be put together compactly the above requirement for a compact arrangement of a rear light Fulfills. Therefore, the compact arrangement of the resultant remains taillight despite the diversity of its forms.

The invention is based on in the embodiments shown in the drawing explained in more detail. It demonstrate:

explanation of the preferred embodiments

How out 1 is visible, the lens 11 a rear light is divided into the following six optically isolated zones: a surrounding annular peripheral zone 16 and an X-shaped central zone 15 on which the light rays from the light sources 22 . 31 for the brake light or the secondary light, as well as four sectors 14 , each delimited by two legs of the X shape and an arcuate section of the peripheral zone, the light beams of the light source 21 for the fog lamp on the upper sector 14 , the light rays of the light source 21 for the direction indicators on the left and right sectors 14 , and the light rays of the light source 21 for the reversing light on the lower sector 14 be directed.

How out 2 emerges, the rear light has a lamp disc 1 , a smaller hemispherical inner hood 2 , a larger also hemispherical outer hood 3 , and the light sources 21 . 22 . 31 for all functions on: direction indicators, fog lamp, reversing light, brake light and auxiliary light.

The lamp disc 1 consists of a diffuser 11 and four screen-shaped partition walls (or sector wall pairs) 13 , The lens 11 is in the usual way over its entire area with numerous honeycomb scatter cells 12 with which they refract the desired light distribution of the respective light sources 21 . 22 . 31 causes. The scatter cells 12 of the six zones depending on the functions (as direction indicators, fog lamps, reversing lights, brake lights, and auxiliary lights), for example, can be colored as follows: The left sector 14 and the right sector 14 (Direction indicators): yellow The upper sector 14 (Fog lamp): white or colorless The lower sector 14 (Reversing light): white or colorless The X-shaped central zone 15 and the annular peripheral zone 16 (Brake light or auxiliary light): red

The two hoods provide optical isolation or independence of the six zones from each other 2 . 3 and the four partitions 13 , Each of the screen-shaped partition walls (sector wall pairs) 13 consists of two quarter circles, perpendicular to the lens 11 standing sector walls, each on their on the lens 11 standing straight-line side are connected to each other and represent the central X-shaped zone with their adjoining side. The outer periphery and the inner periphery of the annular peripheral zone 16 are by the circumference of the inner hood 2 and that of the outer hood 3 shown. The two sector walls of each partition 13 close an angle of 90 degrees and form a "screen wall", which together with part of the hemispherical shell of the inner hood 2 an eighth-spherical space for a light source 21 limit.

So that the light rays from the different light sources 21 . 22 . 31 the four partitions can not be disturbed from each other 13 who have favourited Inner Hood 2 and the outer hood 3 be made from an opaque material. This allows the six individual zones 14 . 15 . 16 undisturbed and independent of each other by the light sources assigned to them 21 . 22 . 31 be illuminated.

This ensures that the light beams from the two side light sources 21 for the direction indicator only on the left and right sectors 14 ( 4 ) from the upper light source 21 for the fog lamp only on the upper sector 14 ( 5 ) from the lower light source 21 for the brake light only on the lower sector 14 ( 6 ) from the inner light source 22 only on the X-shaped central zone 15 , and from the outside light source 31 only on the annular peripheral zone 16 ( 7 ) can come up with.

In the first embodiment, the two light sources 22 and 31 switched on when braking. This results in a -shaped lighting ( 8th ).

If the taillight is used as a side light to warn when driving, only the inner light source 22 switched on.( 7 )

Incandescent lamps are used as light sources 22 and 31 for the ⊕-shaped zones 15 . 16 and LEDs 21 (preferably white ultra bright LEDs) for the four sectors 14 used. Each set of light emitting diodes 21 for one sector 14 is arranged flush on a sector-shaped carrier plate, which with its circular edge on the inner wall of the jacket of the inner hood 2 and with their two straight-line radio sides on the two sector walls of a partition 13 is attached.

Since a parallel bundled reflection is required when using incandescent lamps as the light source, the inner wall of the two hoods 2 and 3 silver-plated and serves as a reflector that reflects the light rays from the incandescent lamp 2 respectively. 3 to the corresponding zone 15 respectively. 16 reflected.

In 9 and 10 a second embodiment of the invention is shown. In this embodiment, the X-shaped central zone 15 not used as a diffuser, but as a reflector. Therefore, one of the zones 15 assigned light source 22 and that on the inner wall of the inner hood 2 coated silver plating waived. Instead, there is a congruent X-shaped reflective sheet 4 on the inside of the lens 11 on the X-shaped zones 15 arranged that from the from to the lens 11 incident light rays are retroreflected, which results in a passive warning (see 11 ). In this second embodiment, the annular peripheral zone corresponds 16 the brake light alone ( 7 ). It can also serve as a secondary light. When used as a secondary light, the lighting has a lower brightness than when used as a brake light.

12 and 13 illustrate a third embodiment of the invention, in which only light-emitting diodes are used as light sources for all the light-emitting components (direction indicators, fog lamp, reversing lights, brake lights, and secondary lights) 51 be used on a common carrier disc 52 are distributed over their area. Since the use of light-emitting diodes as the light source does not require a reflection bundled in parallel, this is the only hood 5 not hemispherical, but basin-shaped or bowl-shaped. Here, the individual light-emitting components are optically isolated from each other by the hood 5 and four partitions 13 , each of which has four partitions 13 is each formed from two rectangular walls and an arcuate wall. Of course, the partitions 13 and the hood 5 also made of opaque material. Serve: those in the two side sectors 14 lying LEDs 51 as the light source of the direction indicator ( 4 ) in the upper sector 14 lying LEDs 51 as the light source of the fog lamp ( 5 ) in the lower sector 14 lying LEDs 51 as the light source of the reversing light ( 6 ), the light-emitting diodes lying in the annular peripheral zone or in the X-shaped central zone 51 as the light source of the brake light or the auxiliary light ( 7 and 8th ).

Out 14 and 15 results in a fourth embodiment of the invention, which differs from the third embodiment only in that the X-shaped central zone 15 is used as a reflector, as is the case with the second embodiment. The LEDs are accordingly 53 with the exception of one of the X-shaped central zone 15 corresponding X-shaped central area over the carrier disc 54 distributed. As in the case of the second embodiment, here is a congruent X-shaped reflective sheet 4 on the inside of the lens on the X-shaped zones 15 glued to the front of the lens 11 incident light rays are retroreflected, which results in a passive warning (see 11 ). In this fourth embodiment, the annular peripheral zone corresponds 16 the brake light alone ( 7 ). It can also serve as a secondary light. Otherwise, the fourth embodiment is similar to the third embodiment.

Compared to the prior art the invention has the following advantages:

• 1) That respect provides different forms of lighting for different applications other than a circular shape or rectangle, which is aesthetics of the taillight reproduced.
• 2) Despite the diversity his form of lighting remains the construction of consideration very easy.
