used in the exemplary embodiment of fig5 a layer 4 see the list of materials given above is coated directly on the semiconductor body 1 the semiconductor body 1 and portions of the electrical terminals 2 3 are enclosed by a further transparent housing envelope 10 the latter causes no change in wavelength of the radiation that has passed through the layer 4 and it is made for instance from a transparent epoxy resin that is usable in led technology or from glass such semiconductor bodies 1 provided with a layer 4 and without an envelope can naturally advantageously be used in all the housing constructions known from led technology such as smd housings and radial housings see fig4 in all the components described above in order to optimize the color impression of the light emitted and to adapt the emission characteristics the casting composition 5 optionally the transparent envelope 15 and or optionally the further transparent envelope 10 may have light scattering particles advantageously so called diffusers examples of such diffusers are mineral fillers in particular caf 2 tio 2 sio 2 caco 3 or baso 4 or organic pigments these materials can easily be added to epoxy resins fig6 8 illustrate emissions spectra fig6 refers to a semiconductor body that emits blue light luminescence maximum at u03bb u02dc 430 nm and fig7 and 8 refer to semiconductor components that emit white light in each case the wavelength u03bb is plotted in nm on the abscissa and a relative electroluminescence el intensity is plotted on the ordinate of the.
