Abstract (en)

[origin: DE102006031076A1] The device has multiple light emitting diode chips (1) and an optical unit with a light entry surface, which is attached to the light emitting diode chips. A light decoupling surface of the light emitting diode chips is optically attached to the light entry surface of the attached optical unit in a refractive index adjustable manner. A gap between the light decoupling surface of the light emitting diode chips and the light entry surface of the attached optical unit is filled with a material, which exhibits a refractive index of 1.3.
