LENS FOR FORMING RADIATING LIGHT DIODE Russian patent published in 2007 - IPC G02B27/09 

FIELD: the invention refers to optical technique.

SUBSTANCE: the lens has in-series installed the inner down the way of radiating of light diode, and the exterior surface. The inner surface of the central zone adjacent to the axle of the lens, has an optical force providing transfer of the image of the radiating site of the light diode on more remote distance from the exterior surface. The exterior surface has a form of a funnel turning with its peak from the radiating site of the light diode. The profile of the exterior surface is such that at first interaction of radiating with the exterior surface full inner reflection takes place and at the second interaction of radiating with the exterior surface refraction of light takes place in the direction primarily perpendicular to the optical axle of the lens.

EFFECT: reduces part of the radiating flow emergent of the forming lens near its axle, increases intensity of emergent beam of light and provision of more uniform distribution of intensity of light falling on the screen.
