FORM HAVING SURFACE WITH COMPLEX LENS PATTERN

PROBLEM TO BE SOLVED: To provide a form for a complex lens diffusion body which shows improved diffused light transmission while diffusing a specular light source. SOLUTION: The form comprises a surface having a morphology of complex lenses wherein the surface asperities have an amplitude of between...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a form for a complex lens diffusion body which shows improved diffused light transmission while diffusing a specular light source. SOLUTION: The form comprises a surface having a morphology of complex lenses wherein the surface asperities have an amplitude of between 1 and 40 μm, a spatial frequency of between 1 and 100 complex lenses per 1 mm2, and between 1 and 40 minor lenses per a major lens.
