1. An imaging device or lighting module, comprising:
a camera or lamp;
a cover element;
a filter element that is connected to the cover element or is part of the cover element, wherein the filter element has a rectangular shape with beveled corners; and
at least one lighting element that emits light in an infrared spectral range, wherein the at least one lighting element is arranged laterally at one of the beveled corners of the filter element,
wherein energy of the emitted light is at least partially absorbed by the filter element and is converted into heat for heating the filter element and the cover element, and
wherein the at least one lighting element is arranged at a distance from the filter element of at most 10 mm, or the at least one lighting element is in direct contact with the filter element to convert the energy of the emitted light into heat.
