Description

Lighting device, rearview device and motor vehicle

The present invention relates to a lighting device of a

Rear view device of a motor vehicle, comprising at least one light source with at least one light emitter, in particular Lorm an LED, for emitting light that can be coupled into a light guide with at least one light funnel and coupled from there to at least to pass through a part of a light transmission unit and to illuminate an area next to the motor vehicle, in particular a Lahrbahnoberfläche of the motor vehicle. It also relates to a rearview device with such a lighting device and a motor vehicle with it.

A rearview device is a type of device that generally complies with the legal requirements for rearview devices in vehicles, especially in motor vehicles. Thus, such a review device provides an at least the legal requirements corresponding image of the rear area, essentially as well as

In the prior art, for example, the image or image from the rear area can be provided by an interior mirror or a camera system with display, and the side and rear areas lying obliquely to the side, substantially the same as, for example, in the prior art the image from the side or obliquely laterally rear area by outside rear view mirrors or camera systems with

Display devices can be provided ready. Such a rearview device is a subset of an indirect vision device and, accordingly, the objects and solutions presented herein may also be applied to indirect vision devices. Examples of this are images and views of objects that are not in the driver's field of vision, that is to say the directions opposite, left, right, below and above the viewing direction, but also the direction of vision of the driver and / or any combinations of these directions his. The view of the driver can not be complete, especially in the direction of sight Satisfactory, for example, obstructions may be caused by vehicle parts of the own vehicle, such as parts of the body, in particular the A-pillar, the roof construction and / or the hood, and obstructions by other vehicles and / or objects outside the vehicle, which can obstruct the view in such a way that the driver can not completely completely satisfactorily or incompletely grasp the situation. In addition, it is possible that the driver is not able to grasp the situation present to him in or out of the line of sight, as it would be necessary to control the vehicle according to the situation. Therefore, a

Rearview device also be designed so that it prepares the information according to the ability of the driver to allow him the best possible detection of the situation.

A rearview device can also be equipped with various lighting devices. Various other features and devices can be found in

Rearview devices installed and / or controlled by means of rearview devices, which in particular camera systems are included.

The light guide 120 consists of three Lichttrichtem 121, 122, 123, each with a arranged next to the light source 110 Lichteinkoppelende l2la, l22a, l23a and a arranged next to the light transmission unit 130 Lichtauskopplungsende l2lb, l22b, l23b, wherein the three light funnels 121, 122, 123 by a substantially flat web 124 are connected. The light transmission unit 130 includes a light window 131, a housing 132, fixing means 133 for the light source 110, and reinforcing ribs 134.

As can be best seen from the Ligures 7 and 8, the Lichteinkoppelenden 12 la, l22a, l23a are flat and substantially parallel to the circuit board 114, while the

Lichtauskoppelenden 12 lb, l22b, l23b flat and are arranged horizontally to a ring surface. The web 124 extends from the Lichteinkoppelenden lla, l22a, l23a to the Lichtauskoppelenden l2lb, 21 l2b, 23b, which are interconnected only via the web 124, as best seen in Figures 8 and 9.

The light transmission unit 130 is provided as a two-component component, namely in the form of an injection-molded part, wherein the housing 132 in addition to supporting and protecting the light source 110 and the light guide 120 within a not shown

Rear view device of a vehicle including the attachment to the

Review device fulfills a variety of functions. The housing 132 simultaneously acts as a diaphragm defining an area illuminated adjacent to the vehicle.

Furthermore, it is with reinforcing ribs 134, in particular with edges, and

Attachment means 133 for the light source 110 and the light guide 120 is provided. In addition, the housing 132 provides high heat dissipation from the light source 110 by being formed of a material having high thermal conductivity.

Each of the LEDs 111, 112, 113 is associated with one of the funnels 1121, 22, 123 in a one-to-one connection, so that the light emitted by the LEDs 111, 112, 113 is guided within the light funnels 121, 122, 123 is going to be in the area of acting as a lens

Light window 131 to be bundled and thus a homogeneous illumination of the

Serve area next to the truck. For this purpose, the optical axis provided by each light beam emitted from the LEDs 111, 112, 113 is to

inclined horizontal plane. As can be seen in Ligur 12, has the optical axis A of the light emitted by the LED 111 to enter the light funnel 121 at Lichteinkoppelende 12 la to be guided by the light funnel 121 and at Lichtauskopp tion end 12 lb emerge from this, an angle a with respect to the level B, which is the bottom of the

Optical fiber 120, which in turn is defined by the underside of the web 124. The angle a is less than 40 °, preferably 35 °, according to the invention. In addition, the angle between the optical axis A and the Lahrbahnoberfläche is also less than 40 °. The same applies to the optical axes of the other LEDs 112, 113, all of which intersect at a single point.

Each of the ligaments 6 to 12 also show the vehicle coordinate system relative to which the circuit board 114 is inclined. The circuit board 114 is actually rotated between 10 and 25 degrees about the x axis, up to 10 degrees about the y axis, and up to 10 degrees around the z axis. Lemer, the light window 132 is rotated by up to 25 ° about the x-axis. These special passions allow a particularly high and homogeneous illumination of the area adjacent to the vehicle to be illuminated, in particular when the lighting device 101 as

Maneuvering light is used.

When using the fourth illumination device according to the invention as a logo lamp, the diaphragm of the light transmission unit 130 provides a logo shape and thus functions as a mask.

The features of the invention disclosed in the foregoing description, in the drawings and in the claims may be essential both individually and in any combination for the realization of the invention in its various embodiments.
