  • Patent number: 9388960
    Abstract: A lighting unit (1) comprising a phosphor element (2) provided for converting pump light to converted light and designed to emit conversion light at an emission surface (6), and at least two pump light sources (3, 8) configured for emitting pump light, wherein the lighting unit (1) is designed such that primary pump light emitted by a first pump light source (3) illuminates the phosphor element (2) at an incidence surface (5), which differs from the emission surface (6), and secondary pump light emitted by a second pump light source (8) illuminates the phosphor element (2) at the emission surface (6).

  • Patent number: 9151464
    Abstract: The present invention relates to a light source unit having at least one LED sub light source unit. Each LED sub light source unit includes three types of LEDs: phosphor converted green LED, orange-red LED with a wavelength of 614 nm-622 nm, and blue LED with a wavelength of 460 nm-476 nm. Light generated by the three types of LEDs is mixed to generate white light.

  • Patent number: 8556448
    Abstract: An airfield lighting device, comprising: at least one first light-emitting diode (LED) on a first base body; a first thermally conductive tube with a heat transmission medium; a first heat sink; and a housing, in which the first base body and the first thermally conductive tube are arranged. The first thermally conductive tube is thermally coupled to the first base body and to the first heat sink. The heat transmission medium can circulate in the first thermally conductive tube, such that heat which is produced by the at least one first LED during operation can be dissipated from the first base body to the first heat sink.

  • Patent number: 7360923
    Abstract: In a light-emitting diode carrier 1, a plurality of light-emitting diodes 9 are mounted on the rear side 3 of the light-emitting diode carrier and project into a plurality of openings 2. During operation, the light-emitting diodes 9 radiate through the openings 2 of the light-emitting diode carrier 1. A film 10 is applied on the front side 4 of the light-emitting diode carrier 1, said film being transmissive to the radiation emitted by the light-emitting diodes and protecting the light-emitting diode carrier from ambient influences.
