Abstract

Claims (27)

1. A method for projecting light in a cabin interior of an automotive vehicle, the method comprising:

providing a light projector in the cabin interior of the automotive vehicle, the light projector configured to adapt to luminous interferences caused by internal lighting elements of the automotive vehicle;

sending data to the light projector regarding the lighting conditions in the cabin interior of the automotive vehicle;

using the data to modify a projection parameter of a light pattern, wherein the projection parameter is at least one of a maximum luminous intensity, an average luminous intensity, a minimum luminous intensity; and

projecting the light pattern, wherein the light pattern includes light pixels such that a modification of the projection parameter affects a luminous intensity of at least one of the light pixels.

2. The method of claim 1 , wherein the projection parameter further includes a shape of the light pattern.

3. The method of claim 1 , wherein the data is sent to the light projector by a vehicle control unit via a Controlled Area Network (CAN) bus.

4. The method of claim 1 , further including sensing an ambient light, with the data and information related to the ambient light.

5. The method of claim 1 , further including obtaining light data regarding an operation of an auxiliary lighting element included in the vehicle, with the data including information related to the operation of the auxiliary lighting element.

6. The method of claim 1 , further including checking an availability of new data by a projector control unit.

7. An automotive light projector comprising a plurality of light sources and a projector control unit configured to:

receive a data regarding lighting conditions in a cabin interior of an automotive vehicle;

adapt to luminous interferences caused by internal lighting elements of the automotive vehicle;

use the data to modify a projection parameter of a light pattern, wherein the projection parameter is at least one of a maximum luminous intensity, an average luminous intensity, a minimum luminous intensity; and

project the light pattern wherein the light pattern includes light pixels such that a modification of the projection parameter affects a luminous intensity of at least one of the light pixels.

8. The automotive light projector of claim 7 , wherein the light sources are solid-state light sources arranged in a matrix arrangement.

9. An automotive projection assembly comprising:

an automotive light projector configured to adapt to luminous interferences caused by internal cabin lighting elements of an automotive vehicle including

a plurality of light sources and a projector control unit configured to:

receive a data regarding lighting conditions in a cabin interior of an automotive vehicle;

use the data to modify a projection parameter of a light pattern, wherein the projection parameter is at least one of a maximum luminous intensity, an average luminous intensity, a minimum luminous intensity; and

project the light pattern, wherein the light pattern includes light pixels such that a modification of the projection parameter affects a luminous intensity of at least one of the light pixels;

operate a vehicle control unit; and

operate a communication element configured to transfer data between the vehicle control unit and the automotive light projector.

10. The automotive projection assembly of claim 9 , wherein the communication element is a CAN bus.

11. The automotive projection assembly of claim 9 , further including a camera configured to sense ambient luminous intensity and configured to send ambient data to the automotive light projector.

12. The automotive projection assembly of claim 9 , further including a communication port that is configured to send or receive information via a communication protocol such as WPAN, WLAN, WMAN or WWAN.
