Abstract

The semiconductor element (1) has at least one light-emitting semiconductor chip (5) encapsulated within a plastics block which is at least partially transparent and which has at least one angled side face, for total internal reflection of the light components emitted at an angle to the required main radiation direction, for deflecting the light in the main radiation direction.
