Abstract
Official abstract text for this publication.
An emitter has a basic unit with at least one emission surface. Accordingly, the basic unit has deep structuring in a region of the at least one emission surface. More specifically, the basic unit has the deep structuring on both a front side and on a rear side in the region of the emission surface for improving emission properties.
First claim
Opening claim text (preview).
The invention claimed is: 1. An emitter, comprising: a basic unit having at least one emission surface with a front side and a rear side, said emission surface having incisions formed therein running from two opposite sides of said front side and transverse to a longitudinal direction of the emitter, said basic unit having deep structuring formed therein in a region of said at least one emission surface on said front side and on said rear side between said incisions and separate from said incisions. 2. The emitter according to claim 1 , wherein said at least one emission surface of said basic unit has at least one rectangular emission surface. 3. The emitter according to claim 1 , wherein said at least one emission surface of said basic unit has at least one circular emission surface. 4. The emitter according to claim 1 , wherein said at least one emission surface of said basic unit is embodied as a filament emitter. 5. The emitter according to claim 1 , wherein said basic unit has a constant thickness in a region of said deep structuring. 6. The emitter according to claim 1 , wherein said deep structuring has a predefinable three-dimensional contour. 7. The emitter according to claim 6 , wherein said deep structuring has a cuboid contour. 8. The emitter according to claim 6 , wherein said deep structuring has a pyramidal contour. 9. An emitter, comprising: a basic unit having at least one emission surface, said basic unit having deep structuring formed therein in a region of said at least one emission surface, said basic unit having at least one first emission surface embodied as a primary emission surface and at least one second emission surface embodied as a heat emission surface, said first and second emission surfaces are aligned substantially parallel to one another and insulated from one another and at least one of said first and second emission surfaces having said deep structuring.
