Funnel shaped light conducting body for use in solar altitude sensor used for e.g. two zones-air conditioning system of motor vehicle, has isosceles trapezium shaped section including profile widened in direction of light entry surface

摘要

The body (101) has a cylindrical section (120) with a light exit surface (121) arranged adjacent to an isosceles trapezium shaped section (110) with a light entry surface (111). Electromagnetic radiations (220) are coupled into the body via the light entry surface and uncoupled from the body via the light exit surface. The isosceles trapezium shaped section emanating from the cylindrical section includes a profile, which is widened in a direction of the light entry surface. The cylindrical section includes side edges (129) running parallel to each other. An independent claim is also included for an optical sensor comprising an absorption element.
