Gunter Waitl has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20080149958
    Abstract: The light-radiating semiconductor component has a radiation-emitting semiconductor body and a luminescence conversion element. The semiconductor body emits radiation in the ultraviolet, blue and/or green spectral region and the luminescence conversion element converts a portion of the radiation into radiation of a longer wavelength. This makes it possible to produce light-emitting diodes which radiate polychromatic light, in particular white light, with only a single light-emitting semiconductor body. A particularly preferred luminescence conversion dye is YAG:Ce.

  • Patent number: 7271425
    Abstract: The invention relates to an optoelectronic component containing an optoelectronic chip (1) and containing a chip carrier (2) that has a central region (3) on which the chip is fixed and that comprises terminals (41, 42, 43, 44) extending outwardly from the central region of the chip carrier (2) to the outside, wherein the chip and portions of the chip carrier are enveloped by a body (5) and wherein the projection of the body and that of each of the longitudinal axes of the terminals onto the contact plane between the chip and the chip carrier are substantially point-symmetrical with respect to the central point of the chip. The invention further relates to an arrangement comprising said component. The advantage of the symmetrical configuration of the component is that the risk of thermomechanically induced failures of the component is reduced.
