Patent number: 9754776Abstract: 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.Type: GrantFiled: March 31, 2010Date of Patent: September 5, 2017Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Cornelia Titia Staats, Gerardus Arnoldus Rita Van Dijk, Rene Theodorus Wegh, Willibrordus Hubertus Martinus Maria Van De Spijker, Martinus Petrus Joseph Peeters

Patent number: 9250470Abstract: The invention relates to an illumination system (10, 12), to a remote phosphor layer (30; 32, 34), to a scattering layer (32), to a luminaire (100), to a display device (300) and to a method of at least partially correcting a light emission characteristic of at least one light source (22) in the illumination system. The illumination system comprises an array of light sources (20) and a remote phosphor layer and/or a scattering layer arranged between the array of light sources and a light output window (40) for emitting the light from the light sources. At least one light source of the array of light sources comprises a light emission characteristic different from the other light sources of the array of light sources.Type: GrantFiled: January 21, 2010Date of Patent: February 2, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gerardus Arnoldus Rita Van Dijk, Andreas Martinus Theodorus Paulus Van Der Putten, Rene Theodorus Wegh, Martinus Petrus Joseph Peeters, René Jan Hendriks

Patent number: 8134311Abstract: The invention relates to a light source for generating light having a spectral emittance in at least a part of the range of 380 nm to 780 nm, the light having a spectral power distribution E(?) as a function of the wavelength ?, and a general color-rendering index Ra, wherein the ratio of the integral spectral power distribution over a first range of 575 nm???650 nm to that of a second range of 380 nm???780 nm is given by the relation: and wherein Bb, ?0.15 and Ra?20. The light generated by the light source has a relatively small disturbing effect on migrating birds, while it still allows acceptable visibility for human beings.Type: GrantFiled: December 12, 2007Date of Patent: March 13, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Maurice Alexander Hugo Donners, Cornelis Jojakim Jalink, Gerardus Arnoldus Rita Van Dijk, Vincent Fischer, Hans Van Sprang

Publication number: 20090072703Abstract: The invention relates to an improved low-pressure gas discharge lamp comprising a gas discharge vessel (1) surrounding a discharge space (2), containing a gas filling, and further comprising means to generate an electromagnetic field (3) and means for generating and maintaining a low-pressure gas discharge. The lamp is characterized in that the discharge lamp is provided with a first phosphor coating on a surface of the gas discharge vessel and with a second phosphor coating, the second phosphor coating being provided on a surface of the lamp that is more remote from the discharge space compared to the first phosphor coating, and the first phosphor coating being selected from the group of thermally stable phosphors. The low-pressure discharge lamp provides increased efficiency and reduced solarisation as compared to commercially available low-pressure discharge lamps.Type: ApplicationFiled: April 24, 2007Publication date: March 19, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Piet Antonis, Maurice Jacques Sofie Elisabeth Sensen, Rolf Erwin De Man, Gerardus Arnoldus Rita Van Dijk
