Abstract (en)

[origin: WO2007036207A1] An illumination unit comprising a luminescence diode chip mounted on a chip carrier and an optical waveguide is specified. The optical waveguide (3) is assembled from at least two separate parts (4, 5), the luminescence diode chip (2) being encapsulated by one of the parts (4) of the optical waveguide (3). A method for producing a luminescence diode chip (2) of this type and also an LCD display comprising an illumination unit of this type are furthermore specified.
