The invention relates to a multi-functional motor vehicle light, namely to a light, by which at least two reflectors are mounted within a housing and each of them is furnished with a corresponding light source, so that each pair of such reflector and a corresponding light source is then able to perform each desired function of the light.
In accordance with the International Patent Classification, such invention belongs to traffic and transporting, namely to lightning equipment for motor vehicles and in particular to lights which are merely intended for lightning of the front area of the vehicle, and therefore in particular to headlights, fog lights or auxiliary lights including cornering lights.
The purpose of the invention is to create a motor vehicle light, which would comprise a housing of relatively small dimensions, having e.g. a diameter of less than 90 mm, in which two reflectors could be mounted together with belonging bulbs, which would each per se enable regular functioning in the sense of combining a fog light with a cornering light, or a cornering light with a direction signaling light, wherein the light transmitted by one of said reflectors would also have to be colored, when desired A headlight is proposed in GB 1,187,846, having a double reflector, wherein a smaller inner reflector is mounted within a larger outer reflector, namely in front of said outer reflector. In such a manner, overall dimensions of vehicle lights may be reduced, but the light stream of the outer reflector, which is veiled by the inner reflector, may be essentially hindered. In order to avoid such deficiency, a Fressnell lens may be mounted between the bulb of the outer reflector and the rear surface of the inner reflector, by which the rays from the bulb of the outer reflector are appropriately redirected, by which however consequently a pretty inappropriate light pattern is obtained, which is by taking into consideration quite rigorous formal requirements in this field pretty useless, if practical application of such vehicle light is expected.
Moreover, a headlight is proposed in DE 295 19 938 U or EP 0 779 474, which is also furnished with a double reflector, again with an outer reflector and an inner reflector arranged therein, which are arranged at least approximately coaxial with respect to both optical axis thereof. The inner reflector comprises preferably vertical lateral walls, which are approximately parallel with respect to corresponding optical axis, while the outer reflector is a free surface reflector having surfaces curved in such a manner that light rays are directed nearby the inner reflector. The obtained light pattern seems to be better than those obtained by GB 1,187,846, however by anticipating that the overall dimensions of the outer reflector are sufficiently large. When taking into consideration that the inner reflector is intended for functioning as a deep beam light or a fog light of considerable dimensions, then the dimensions of the outer reflector are correspondingly more extensive. This practically means that such approach may be realized only in a headlight but not also in smaller autonomous lights like fog lights.
The proposed invention relates to a multi-functional motor vehicle light, which comprises a housing, which is furnished with a light permeable front wall and within which a front reflector together with a belonging light source and a rear reflector (2) together with a belonging light source are mounted. In accordance with the present invention, both optical axis of said reflectors extend at least approximately parallel to each other, wherein the optical axis of the rear reflector is located above the optical axis of the front reflector, and wherein the rear reflector comprises optical surfaces, which are located above the optical axis of the front reflector. At the same time, the front reflector comprises optical surfaces, which are located below the optical axis of the rear reflector, and besides, the front reflector further comprises a protrusion, which is furnished with a corresponding optical surface and a rear surface and which is extended upwardly towards the area in front of the light source of the rear reflector, namely into the area of the optical axis of the rear reflector. Consequently, the front reflector comprises such an optical surface, which is located below the optical axis of the rear reflector, and also an optical surface, which is located in the area of the optical axis of the rear reflector, or optionally above said optical axis. In a further possible embodiment, the front reflector comprises an upwardly into the area of the optical axis of the rear reflector extended protrusion, which is furnished with an optical surface as well as with a colored rear surface, which is faced towards the light source of the rear reflector.
The invention will be described in more detail by means of an embodiment, which is shown in the attached drawing, wherein
Fig. 1 is a cross-section of a light according to the invention along the diametrical plane thereof; and
Fig. 2 is a front view of the light according to Fig. 1.
A light according to the invention (Fig. 1) comprises a housing 3 with a light permeable front wall 31, in which a front reflector 1 with a belonging light source 11 as well as a rear reflector 2 with a belonging light source 21 are mounted. Both optical axis 10, 20 of said reflectors 1, 2 extend at least approximately parallel to each other, and the optical axis 20 of the rear reflector 2 is located above the optical axis 10 of the front reflector 1. The rear reflector 2 is furnished with optical surfaces 22, which are located above the optical axis 10 of the front reflector 1, and the front reflector 1 is furnished with optical surfaces 12, which are located below the optical axis 20 of the rear reflector 2, as well as with a protrusion 13, which is furnished with corresponding optical surface 14, which protrudes upwards into an area 2 in front of the light source 21 i.e. in the area of the optical axis 20 of the rear reflector 2. The rear surface 15 of said protrusion 13 on the front reflector 1, which is faced towards the rear reflector 2, is optionally colored, which consequently leads to coloring of the light, which is transmitted by the rear reflector 2 throughout the front wall 31 of the light.
By appropriate determining optical surfaces 22 of the rear reflector 2, the last one is on the one hand and regardless to relatively small dimensions of the housing 3 able to redirect the light generated by the light source 21 nearby the protrusion 13 of the front reflector 1 in order to establish a perfectly regular operating fog light, while on the other hand thanks to said protrusion 13 and said optical surface 14 available thereon the complete optical surface 12, 14 on the front reflector 1 is sufficient for establishing a further function like e.g. a cornering lamp or a day light. The fact that the light source 21 of the rear reflector 2 is actually veiled by the front reflector 1 may also be pretty interesting from the designers aspects, since the light source 21 is practically invisible, when observed from the front side (x) iv the vehicle through the front wall 31 of the light housing 3 (Fig. 2).
