Abstract

The invention relates to a wide-radiating lighting unit, comprising a lens for adjustment of light exiting from a light source. The lens defines a specific light distribution, whereby the light intensity above the 65° radiation angle is less than 10% of the light intensity directly under the fixture and wherein the light intensity at 35° is greater than 90% of the light intensity directly under the fixture. The side of the lens remote from the light source is provided with a microstructure, such as, for example, a roughening, which enlarges the luminance image of the light source.
