Definitions
- the invention relates to an interior light for means of transport, such as an airplane or a motor vehicle, according to the generic features of claim 1.
- a generic interior light for a motor vehicle is disclosed in EP 1 344 684 AI.
- the interior light for means of transport, in particular for motor vehicles is provided with a diffusing screen made of glass or plastic which covers the illuminant or illuminants and which has on its surface optical elements for scattering or deflecting the emitted light.
- This interior light should preferably serve as a reading light.
- At least some of the optical elements provided on the lens have a first central, non-diffusely scattering area and a second, diffusely scattering area surrounding this first area completely or partially.
- This special structure in the edge area of the optical elements provided on the diffusing screen reduces the glare of the interior light or the reading light it forms.
- the edge areas of the optical elements which are not primarily intended for light distribution, reduce the glare of the vehicle occupants or the viewer with their diffusely scattering surface structure.
- the disadvantage of this type of interior light is that it is generally arranged separately from a glass roof.
- the glass surface or the glass roof and the interior light therefore require space and in particular in the case of a glass roof the space at which the interior light is usually located is occupied by the glass roof. This leads to the interior light must be placed in an unsuitable location. This leads to less optimal illumination of the interior of the vehicle.
- the object of the invention is therefore to provide a type of interior light which can be easily integrated into a glass surface and thus does not require any further installation space.
- the present invention therefore, although a glass surface is arranged, aims to arrange the interior light in its traditional place without interfering with the function of the glass roof.
- the arrangement of the interior light means that the glass surface should remain largely usable as a glass surface.
- the interior light is advantageously built directly into the glass roof, so that when the light source is switched off, only a small frame is visible, which separates the glass of the lens of the interior light from the glass pane of the glass roof.
- the glass of the interior light is transparent to light like the normal glass of the glass roof.
- the function of the glass roof is not restricted by the arrangement of the interior light in the glass roof. Switching on the interior light, for example in the dark, causes light to be coupled out of the glass. As a result, the entire decoupling surface serves as a lamp. As a result, the space for the interior lamp can be saved. Because the interior light is integrated in the space of the existing glass roof.
- Fig. 1 is a schematic representation of an interior light in the glass roof
- Fig. 2 is a schematic representation of the individual components of the interior light in the glass roof
- Fig. 3 is a view of the coupling element
- Fig. 4 is a section through the transparent coupling element.
- Fig. 1 shows a schematic representation of an interior light in the glass roof 2 of a motor vehicle.
- the interior light with a central light 1 and two down lights 3 is arranged in recesses in the glass of the glass roof 2.
- the interior light 1, 3 consists of a housing 4, which has an annular circuit board 5 with light-emitting diodes 6 and the associated electronics, an annular receiving slot for the circuit board 5 in the housing 4 and a coupling element 7 arranged inside the housing 4, which is preferably a glass pane corresponds.
- the supply and control of the circuit board 5 takes place via supply lines 8, which are integrated into the glass, preferably laminated glass, of the glass roof 2 similar to a heatable rear window.
- the leads 8 lead from the glass frame 9 to the housing 4, in which the circuit board 5 and the decoupling element 7 are inserted.
- the light-emitting diodes 6 arranged on the circuit board 5 emit their light laterally into the coupling-out element 7, which is preferably a transparent pane made of glass or plastic. Openings 10 are arranged in the housing 4, each of which is assigned to a light-emitting diode 6. The light of the light-emitting diode 6 is coupled into the coupling-out element 7 through these openings 10. The light is passed through the decoupling element 7 and leaves the decoupling element 7 into the vehicle interior on its surface facing the vehicle interior.
- interior lights 1, 3 are arranged in the glass roof 2, which, depending on the size and emitting light intensity, serve as interior lights 1 or down lights 3, ie reading lights.
- the interior light 1 with the larger decoupling element 7 serves as a central light, while the interior lights 3 with the small serve as a reading light.
- the supply and control lines 8 are guided from the edge of the glass roof 2 in the glass composite to the housing 4 of the interior lights 1. These supply and control lines 8 are electrical lines which are led in the laminated glass to the housing 4 of the interior light 1 and thus to the circuit board 5 with the light-emitting diodes 6 arranged thereon.
- the circuit board 5 is formed in each case a flat ring which can be inserted into a groove in the housing 4 and is arranged around the edge of the coupling element 7.
- the circuit board 5 is arranged in the housing 4 such that the ring is completely covered by part of the housing 4.
- the housing 4 has openings 10 at certain points, which are assigned to the individual light-emitting diodes 6. The light from the light-emitting diodes 6 can then pass through these openings 10 and be coupled into the glass pane 7.
- the number of light-emitting diodes 6 and the size of glass pane 7 differentiate the function of interior light 1 from pure interior light 1, from reading light 3, ambient light function, make-up lighting, down light or, for example, from a sleep light.
- the interior light 1, 3 can be provided integrated between an inner pane and an upper outer pane 12. These discs are primarily used for stabilization and also to protect the components arranged between them.
- the upper outer pane is provided as the roof of a vehicle and is made of a hard glass, such as mineral glass, so that the glass roof 2 is protected when harder objects hit the glass roof 2 from above.
- the inner pane 11 can also be made of mineral glass.
- the three layers of glass are connected to form a laminated glass pane. So that the glass composite does not build up extremely, the housings 4 are very flat, which form part of the interior light 1, 3.
- the geometry of the housing 4 with the decoupling elements 7 located therein is different, for example square, rectangular, round, oval or any other geometrical Shape.
- the housing 4 also have a cover so that the circuit boards 5 with the various components therein are no longer visible.
- the flat housing 4 with the coupling elements 7 do not have to be flat, but can also be adapted to the roof contour.
- the interior light 1, 3 shows a schematic representation of the individual components of the interior light 1, 3 in the glass roof 2.
- the 3 has a housing 4, into which a circuit board 5 with the electronics and the light-emitting diodes 6 and into which a decoupling element 7 can be inserted as a luminous element.
- the housing 4 has a groove into which the circuit board 5 with the light-emitting diode 6 and the electronics can be inserted invisibly.
- the circuit board 5 can be inserted as a ring in the groove 13 provided for this purpose, the light-emitting diodes 6 being arranged on the circuit board 5 on the inside toward the glass.
- the housing 4 then has openings 10 assigned to the light-emitting diode 6 arranged on the circuit board 5 for coupling the light from the light-emitting diodes 6 into the coupling-out element 7, the coupling-out element 7 corresponding to a glass pane which is arranged in a further groove 14 in the housing 4. This entire component is then arranged between two glass panes and joined to form the laminated glass.
- the electrical lines 8 for supplying the circuit board 5 are led through this laminated glass from the roof frame to the housing 4.
- the glass roof 2 has the contour of the roof, which is shown flat, but can also be curved.
- the glass pane of the decoupling element 7 is curved, so that a uniform surface of the glass roof 2 is formed without corners and edges.
- the two inner and outer panes forming the laminated glass are then curved to form the shape of the glass roof 2.
- the outcoupling element 7 is preferably oval in shape, with light outcoupling grooves 11 formed in the surface.
- the light decoupling grooves 11 have a V-shaped structure, so that the light on the surface couples out in the direction of the vehicle interior.
- the surface of the decoupling element 7 is such that the light remains trapped therein by total reflection and only emerges from the decoupling element 7 at the light decoupling grooves 11.
- the housing can also have any other geometric shape and can be square, rectangular or round.
- the interior light 1 has a square coupling element 7 and a square luminous element.
