    Abstract: PROBLEM TO BE SOLVED: To present a light-emitting diode (LED) chip that already has elements for improving the radiation output coupling and/or to convert electromagnetic radiation, thus to miniaturize a light-emitting device.
    SOLUTION: The LED chip, which has an array of epitaxially grown semiconductor layers, is so structured that the LED has a covering object transmitting radiation, the covering object is put on a radiation output coupling surface postpositioned in an LED chip radiation direction and has a first principal plane oriented in the radiation output coupling surface, a second principal plane oriented toward a direction which is reverse to that of the radiation output coupling surface, and a side surface that connects the first and second principal planes, and a junction layer is arranged between the radiation output coupling surface and the covering object, which directly joins and fixes the covering object to the semiconductor layer array, and the junction layer includes at least one conversion layer that has a light-emitting conversion material.

    Abstract: An illumination device (1) for backlighting a display is disclosed. The illumination device comprises: at least one semiconductor body (3), suitable for generating electromagnetic radiation of a first wavelength range, a first wavelength conversion substance (30), which is disposed downstream of the radiation-emitting front side (6) of the semiconductor body (3) in the emission direction (8) thereof and is suitable for converting radiation of the first wavelength range into radiation of a second wavelength range, which is different from the first wavelength range, and a second wavelength conversion substance (31), which is disposed downstream of the radiation-emitting front side (6) of the semiconductor body (3) in the emission direction (8) thereof and is suitable for converting radiation of the first wavelength range into radiation of a third wavelength range, which is different from the first and second wavelength ranges. A display comprising such an illumination device (1) is furthermore described.
