Optical layer and light fixture with such an optical layer

An optical layer (1) made of a light-permeable material comprises a surface (13) and an optical micro-structure (11) having a plurality of elevations (111). The elevations (111) in the micro-structure (11) project from a reference plane (15) that is parallel to the surface (13). Each elevation (111)...

Beschreibung
Zusammenfassung:	An optical layer (1) made of a light-permeable material comprises a surface (13) and an optical micro-structure (11) having a plurality of elevations (111). The elevations (111) in the micro-structure (11) project from a reference plane (15) that is parallel to the surface (13). Each elevation (111) in the micro-structure (11) has a flank section (112) adjoining the reference plane (15), said flank section forming a uniform angle (α) with the reference plane (15). Said uniform angle (α) is in a range of approximately 10° to approximately 26° or in a range of approximately 13° to approximately 23° or in a range of approximately 15° to approximately 20°. The optical layer (1) according to the invention allows a light fixture to achieve a high light output rate (LOR) and at the same to produce a preferred light distribution curve (LVK).
