Abstract
An inventive LED-based lamp, lamp cover component, and methods for manufacturing thereof are disclosed which provides a light diffusive lamp cover having a diffusivity (transmittance) that is different for different areas (zones or regions) of the cover. The diffusivity and location of those areas are configured so that the emission pattern of the whole lamp meets desired emissions characteristics and optical efficiency levels. The diffusive cover may have any number of specifically delineated diffusivity areas. Alternatively, the cover may provide a gradient of increasing/decreasing diffusivity portions over the cover.
