# Negative-pressure element for a (negative-pressure) work surface

## Abstract

The invention relates to a negative-pressure element for arrangement in and/or on a negative-pressure work surface in order to selectively illuminate said negative-pressure work surface, the negative-pressure element comprising: at least one connection which is designed to connect a negative pressure and/or a negative-pressure device; a diffuser layer, the diffuser layer having a perforation at least in sections; a translucent layer, in particular a light-guiding layer, the translucent layer having a perforation at least in sections and being designed to couple light into the diffuser layer; wherein the perforation of the diffuser layer and of the translucent layer is designed such that, when a negative pressure is applied to the negative-pressure element, air can flow through said perforation towards the negative-pressure device; at least one light source, in particular at least one LED, which is configured to emit light towards the translucent layer; at least one volume which is designed to distribute a negative pressure applied to the at least one connection to the perforation, in particular to at least one part of the perforation; and wherein the negative-pressure element is designed such that it can be arranged on a perforated negative-pressure work surface or such that the negative-pressure element can be integrated into a recess in a work surface or a negative-pressure work surface.
