Embodiment Construction

[0020] In a first exemplary embodiment, the lighting device is designed as a high-resolution headlight with a plurality of light-emitting diodes arranged in a matrix. In particular, the individual light emitting diodes can be integrated as a solid state LED array. The headlight also includes a control unit, which calculates the light distribution and can generate the light distribution by correspondingly controlling the individual light-emitting diodes.

[0021] When one of the light-emitting diodes fails, a gap is created in the light distribution 1 which corresponds to the failure of a pixel 2 or a plurality of pixels 2 of the light distribution 1 . Corresponding vacancies with at least one pixel 2 failure in figure 1 The light distribution in 1 is shown. Before the adjustment by the method according to the invention, the transition to the adjacent pixel 3 is extremely harsh.

[0022] As a reaction to the failure of one of the light-emitting diodes, the control means can ...

Abstract

A method is provided for operating an illuminating device for a vehicle that features means of influencing light or a plurality of light sources for the targeted generation of pixels of a light distribution 1. In the event of failure of at least one pixel 2 of the light distribution 1 caused by a defect in one section of the means of influencing light or by malfunction of one of the light sources,at least one non-defective section of the means of influencing light or or at least one non-malfunctioning light source is actuated in order to correct the light distribution 1. The at least one non-defective section of the means of influencing light or at least one of the non-malfunctioning light sources is actuated in such a way that at least one pixel 3, 4, 5, 6 of the light distribution 1 adjacent to the at least one malfunctioning pixel 2 is reduced in its brightness.

Description

technical field [0001] The invention relates to a method for operating a lighting device for a motor vehicle according to the preamble of claim 1 and a lighting device for a motor vehicle according to the preamble of claim 7 . Background technique [0002] A method and a device of the aforementioned type are known from CN101945513A. The device described in this document has a plurality of light emitting diodes (LEDs). When one of the LEDs fails, the other LEDs are activated in such a way that they glow brighter. The failure of the light-emitting diodes is thus compensated for with regard to the total intensity of the light emitted by the lighting device. [0003] The light distribution of the LED matrix headlight is produced by superimposing the light of the individual light-emitting diodes. In this case, the matrix headlight can include 100 light-emitting diodes. In high-resolution headlights such as so-called μAFS-LED headlights or headlights with a pixel aperture base...
