ABSTRACT:
This invention relates to apparatus for electronically recording using a xerographic machine and, more particularly, to an assembly of monoliths containing light emitting diodes (LED's) that yields a relatively long array of LED's with high light density and a contiguous set of light centers. A fiber optic cover is placed over the exposed surfaces of the LED's to counter the effects of the divergent angle of light emitting from the LED's and to protect the LED's from damage. A gel having a relatively high refractive index is applied between the LED's and the fiber optic cover to further counter the effects of the divergent angle of light.
