<p>The invention provides a three dimensional lighting assembly comprising a plurality of cylindrical lighting units (102) linked by structural connecting strands (104), the structural connecting strands (104) serving to hold the assembly in a configuration whereby it mimics the secondary and/or tertiary and/or quaternary structure of a protein, the cylindrical lighting units (102) representing alpha helical regions of the protein and the structural connecting strands (104) representing non- alpha helical regions of the protein.</p>
