Patent ID: 7738754

Claim:
An optical component having an incident surface on which light is incident and a light-exiting surface that is roughly parallel to the incident surface, wherein: when a roughly collimated light is incident on the incident surface, light intensity of an outgoing light from the light-exiting surface is anisotropic along an azimuth angle of 30 to a normal line of the light-exiting surface, and a ratio of a maximum intensity value, which is the highest intensity value in an intensity distribution of the light intensity of the outgoing beam along the azimuth angle 30, and a minimum intensity value, which is the lowest intensity value in the intensity distribution of the light intensity of the outgoing beam along the azimuth angle 30, of the anisotropy (maximum intensity value/minimum intensity value) is 1.2 or more; and a plurality of irregular lens rows are aligned on at least one of the incident surface and the light-exiting surface, extending in a direction forming an angle within a range of −30 to 30 on the incident surface or the light-exiting surface to one direction along the incident surface or the light-exiting surface.
