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.
