  • Patent number: 9754776
    Abstract: The invention relates to a luminescent converter (10, 12) for a phosphor-enhanced light source (100, 102, 104). The luminescent converter comprises a first luminescent material (20) configured for absorbing at least a part of excitation light (hv0) emitted by a light emitter (40, 42) of the phosphor-enhanced light source, and for converting at least a part of the absorbed excitation light into first emission light (hv1) comprising a longer wavelength compared to the excitation light. The luminescent converter further comprising a second luminescent material (30) comprising organic luminescent material (30) and configured for absorbing at least a part of the first emission light emitted by the first luminescent material, and for converting at least a part of the absorbed first emission light into second emission light (hv2) having a longer wavelength compared to the first emission light.

  • Publication number: 20090243487
    Abstract: A high-pressure discharge lamp has an outer envelope (1) in which a discharge vessel (11) is arranged. The discharge vessel encloses a discharge space (13) with an ionizable filling. The discharge vessel has two mutually opposed neck-shaped portions (2,3) through which current supply conductors (4,5) extend to a pair of electrodes (6,7) in the discharge space. A lamp base (8) of electrically insulating material supports the discharge vessel. The lamp base also supports the outer envelope (1). The outer envelope encloses the current supply conductors and is connected to the lamp base in a gas-tight manner. By controlling the atmosphere in the outer envelope, a simplified and compact high-pressure discharge lamp is provided with an accurate positioning of the discharge vessel with respect to the optical axis of the lighting system. The high-pressure discharge lamp can be suitably applied in an assembly with a reflector.
