as layers are removed as seen in fig5 a 5d the material for the polymer film is between 0 5 and 2 mm thick and preferably between 0 5 and 1 mm thick as best can be seen in fig5 the adhesive 16 can be distributed over the polymer sheets using varying configurations and can be biodegradable in this regard the adhesive 16 can be formed in x patterns around the periphery 18 of the polymer sheet 14 additionally the adhesive can be distributed across the sheet in an x pattern or in stripes or strips over the entire sheet when it is the intention for the material to collect airborne materials the adhesive can be evenly distributed across the face of the material the stack of polymer sheets can weigh less than 5 ounces the stack of polymer sheets can also be coupled either to the support structure or the light emitting surfaces to prepare a surface for cleaning under the present teachings a stack of polymer layers are coupled to a light emitting structure after a desired or predetermined amount of time or the accumulation of an undesirable amount of material the outermost polymer layer can be removed from the stack of polymer layers example embodiments are provided so that this disclosure will be thorough and will fully convey the scope to those who are skilled in the art numerous specific details are set forth such as examples of specific components devices and methods to provide a thorough understanding of embodiments of the present disclosure it will be apparent.
