Description

The invention relates to a lighting device for motor vehicles.

Lighting devices are known for motor vehicles that are intended to illuminate the road. Depending on the orientation of the lighting fixtures, a distinction is made between high beam and low beam headlights.

light. The high beam provides better illumination, but it also causes blinding of oncoming vehicles.

Electromechanical devices for the optimal alignment of the bundled light beam are also known. However, the high technical complexity and thus the susceptibility to interference are disadvantageous.

It is therefore an object of the invention to provide a lighting device for motor vehicles which enables optimum illumination of the route, whereby this can also be adapted to changing conditions.

This object is solved by the features of claim 1.

For this purpose, the invention provides for creating a lighting device that has light bulbs that have at least two filaments that are arranged horizontally, i.e. next to one another, with each filament having its own reflector or with a screen arranged between the filaments. It is also possible to arrange filaments vertically and/or to combine them with horizontal filaments. Each filament can be switched individually, so that a specific orientation of the light beam can be achieved by selecting the respective filament or by combining filaments accordingly, since each filament with its reflector or screen is aligned differently in space. The lighting device has a suitable control device for controlling the filaments.

Preferably, the control device is equipped with sensors that register oncoming vehicles so that the light beam is automatically aligned in a glare-free manner.

According to another preferred embodiment, the control device is coupled to the steering so that when cornering, the light cone always completely illuminates the road without dazzling oncoming traffic.

However, manual control is also possible.

A further lighting device according to the invention can also be realized by providing corresponding headlights instead of horizontally and/or vertically arranged filaments.

Further advantageous embodiments are characterized in the subclaims.

The invention is explained in more detail below with reference to drawings. They show

The light bulb 10 according to Fig. 1 has two filaments 11, 12, which have a different spatial orientation. Both filaments 11, 12 are shielded from each other by a screen 13, so that their light cones do not diverge. The base 14 of the light bulb 10 has standard plug contacts 15 for connection. In contrast, the three filaments 16, 17, 18 of the light bulb 19 according to Fig. 2 have reflectors 20, 21, 22, whereby here too the orientation of the light cones differs from each other.

is sufficient. The plug contacts 2 3 are connected inside the base by means of a commutator 25 or, according to another variant, the plug contacts 23 are connected directly to the filaments 16, 17, 18 as in Fig. 1. The top view according to Fig. 3 shows how dazzling of oncoming traffic is prevented. Usually, the vehicle 29 driving around a right-hand bend would dazzle the oncoming vehicle 30. The oncoming vehicle 27 is registered by sensors of the lighting device and dazzling is avoided by switching the filaments 11, 12, 16, 17, 18 accordingly. In addition, the light cone 34, which is turned slightly to the right, and the light cone 33, which is turned slightly to the left, illuminate the edges of the road 31 and 32 well. The control circuit can also be connected to the steering so that the light cone is automatically adjusted to the change in direction. Fig. 3 shows a horizontal arrangement of three headlights 26, 27, 28 for forming the lighting device according to the invention, which are used in the same way as the filaments 11, 12, 16, 17, 18. Fig. 5 shows a schematic of a headlight 36 which has two bulbs 38, 39 inside it, which are shielded from each other by a screen 37.
