AI Technical Summary

Technical Problem

Existing marten deterrent systems for vehicles require additional components, which is inconvenient and inefficient.

Method used

Integrate a DC/DC converter and a dummy load within the vehicle's headlights to convert electrical energy into a deterrent sound frequency range, using the headlights' control electronics to emit an unpleasant sound for martens without additional components.

Benefits of technology

Effectively deters martens by utilizing existing headlights, minimizing additional hardware needs and ensuring the headlights remain powered to generate the deterrent sound without lighting, thus protecting vehicle components.

Abstract

The present invention relates to a headlight of a motor vehicle. The invention further relates to a motor vehicle with such a headlight. The headlight (10) has at least one light source (11) and control electronics (12) for controlling the at least one light source (11), wherein the control electronics (12) has a DC / DC converter (13), the DC / DC converter (13) being configured to convert an input voltage applied to an input of the DC / DC converter (13) into an operating voltage for the at least one light source (11), the control electronics (12) having a switchable dummy load (14), the control electronics (12) being configured to operate in a light mode and in a protection mode, wherein in the light mode the DC / DC converter (13) is activated and the at least one light source (11) is supplied with the operating voltage to generate a light function.wherein in the protection mode the DC / DC converter (13) is activated, the dummy load (14) is connected and at least one light source (11) is disconnected from the DC / DC converter (13), wherein the control electronics (12) is designed to output a sound signal in a frequency range that has a deterrent effect on animals in the protection mode.
