Definitions
- Semiconductor materials for luminescence diode chips sometimes have a refractive index of well over 3.
- the medium adjacent to the chip in conventional luminescent diode components, usually this is air or plastic, has a significantly lower refractive index.
- the associated large jump in the refractive index at the interface between the luminescence diode chip and the adjacent medium leads to a relatively small critical angle of the total reflection, so that a large part of the electromagnetic radiation generated in an active region of the chip is reflected back into the chip from this interface.
- the highly transparent casting compounds have undesirable chemical and mechanical properties, which also limits the technical application of the compounds.
- the emission of the light can be particularly easily restricted to a smaller area according to the invention.
- the light-emitting area consists of a plurality of partial lighting areas arranged at regular intervals from one another
- the emission light is coupled into the lens body 41 at the light exit surface 8 and the exit light bundle is designed in accordance with the lens shape.
- Fresnel lens 42 is used here as the optical device for changing the exit light bundle, which, by means of the method according to the invention, using rapidly rotating milling tools or suitable etching techniques over the light-emitting area 32 on the light exit surface of the window layer 2 is trained.
