Definitions
- the invention relates to a lamp, in particular for Motor vehicles with at least one light guide rod, the one or more light entry faces at the front and one or more light exit surfaces in particular has along the light guide rod, and with one or several, in particular designed as light emitting diodes Light sources.
- Luminaires with light guide rods are well known. So is e.g. from DE 41 29 094 A1 a signal lamp for Motor vehicles have become known in which several Light guide rods in a parallel arrangement to each other are provided. In these light guide rods is by means of a Light-emitting diode radiated light at one end, which is distributed over the length of the light guide rod. On the side opposite the light exit surface is the light guide rod with a multitude of prisms provided on which the light rays in the direction of Light exit surface can be deflected.
- lights are also known, in which parallel light guide rods be used where the light entry surfaces however, they are not on one level, but on the side are offset, as this is required by the shape of the lamp becomes.
- these lights e.g. with trapezoidal or parallelogram-shaped lampshade, the individual Light sources not attached to a common board as this would then have to be carried out in stages.
- the individual light sources are therefore each on one attached its own circuit board, and the lamp housing must be used for each board with a holder for the Circuit board. This configuration is both constructively as well as in terms of assembly effort complex and therefore also expensive.
- the invention is therefore based on the object Provide luminaire that is structurally simple and is quick to assemble.
- the Light guide rods may be arranged parallel to one another, however, the light entry surfaces are not in one plane but are staggered in steps.
- This task is for a lamp of the type mentioned Art solved according to the invention in that the Light entry surface opposite the longitudinal axis of the Light guide rod is inclined.
- the invention Luminaire can be used as a signal light, as an interior light module, as Vehicle position lamp or as Vehicle lighting application can be used.
- the geometric Arrangement of the light guide rods a non-planar arrangement of the Light exit surfaces and it will be a simple construction proposed the establishment and contacting of the the light sources assigned to the light guide rods in one Level and thus e.g. the use of a simple Board allowed. This leads to the build up anyway structurally simple and the luminaire can be installed quickly and is inexpensive.
- the axis of the Light cone of the light source and / or the central axis of the Light source opposite the longitudinal axis of the light guide rod is inclined. This will be another option created the course of the light rays within the To change the light guide rod. With this possibility however, due to the inclination of the light source, the direction of the rays striking the light entry surface changed.
- the inclination of the light entry surface and the inclination of the Light source are chosen so that the light rays within the light guide at least run as with conventional light guide rods that are illuminated normally become. In this way the light source can be tilted, i.e. be arranged at an angle, the course of the Rays of light within the light guide rod through the Inclination of the light entry surface is corrected.
- the inclination of the light sources can also on which the light source or light sources are arranged to be inclined. So it is not required that the light entry surfaces of all Light guide rods in a plane perpendicular to the longitudinal axis of the rod lie. Rather, the ends of the light guide rods follow the slope of the board, so due to this Alignment of the light guide rods e.g. also trapezoidal Tail lights can be optimally illuminated without a separate circuit board for each individual light source must be used.
- the directions of inclination are preferred Light entry surfaces and the axis of the light cone Light sources with respect to the longitudinal axis of the light guide rod opposed to each other. Is e.g. the light entry area tilted to the right, then the associated light source inclined to the left. This will cause the Light rays within the light guide rod none or only experienced minor changes in direction.
- the invention thus sees an arrangement of one or several light guide rods in front, an embodiment of the respective light entry surfaces is proposed it allows the light sources assigned to the light guide rods to be arranged on one level, e.g. with one, level board. Own the individual Light guide rods several coupling surfaces, e.g. on the opposite side, can use the same principle be moved.
- the Light entry surfaces of the side by side Light guide rods form a kind of sawtooth profile. This is due to the fact that the direction of the inclination of the Light entry surfaces against the direction of the inclination of the Is light sources.
- Fig. 1 three are designated by 10 in total Light guide rods shown, the light guide rods 10 are arranged one above the other and one each Have light entry surface 12, the one front end is provided. The viewer facing, the light guide rods 10 each have one Light exit surface 14, which is behind a trapezoidal lamp glass 16, which with dashed Lines are only hinted at.
- Light source 18 embodied by a light emitting diode 20 becomes.
- These light emitting diodes 20 are on a single board 22 arranged, the board 22 opposite the Vertical direction is inclined by the angle ⁇ .
- the board 22 runs approximately parallel to the adjacent side edge 24 of the lighting glass 16.
- the light emitting diodes 20 each emit the associated one Light entry surface 12 of the respective light guide rod 10 on, the light entry surface 12 also inclined is. However, the direction of inclination runs opposite to the direction of inclination of the board 22. Die Light entry surfaces 12 are therefore at an angle ⁇ inclined to the vertical. This causes the Light rays from the light emitting diodes 20, e.g. conical be emitted at the light entry surface 12 in such a way be broken that the cone axis 32 of the light cone in essentially parallel to the longitudinal axis 30 of the light guide rod 10 runs. This means that despite the inclined Arrangement of the board 22 of the beam path within the Light guide rods 10 is similar to that as if the Light guide rods 10 for vertical light entry surfaces 12 illuminated with light sources 18 arranged parallel thereto become.
- the position of the light guide rods 10 can be such can be changed, in particular the light guide rods 10 to be moved parallel to each other in such a way that not only rectangular but also parallelogram and Trapezoidal lighting glasses 16 optimally illuminated can be.
- the emitted by the LED 20 and light rays extending within the light guide rod 10 26 are uniform over the entire length of the Distributed light guide rod 10 and broken so that it on the opposite of the light exit surface 14 Side provided prisms 28 hit and from there in Direction of the light exit surface 14 are deflected.
