Publication number: 20150146407Abstract: According to an aspect of the present invention, a lighting device (2) is provided. The lighting device (2) comprises a wavelength converting layer (21) having a curved shape and a light source (22) arranged to emit light towards the wavelength converting layer (21). The wavelength converting layer (21) intersects a plane extending through the light source (22) and being parallel with the optical axis of the light source (22), at a curve given, in a polar coordinate system centered at the light source (22), by the equation: R(?)=k·I(?)1/2±D, wherein k is a constant, 0 is an angle with respect to said optical axis, /(?) is a function defining a luminous intensity profile of the light source and D is a deviation ranging from zero to 20% of the maximum value of said curve, Rmax. The present invention is advantageous in that the lighting device (2) has a more uniform color distribution of emitted light across the wavelength converting layer (21) and the risk of color gradients and artifacts is reduced.Type: ApplicationFiled: May 28, 2013Publication date: May 28, 2015Inventors: Erik Paul Boonekamp, Shufen Tsoi, Andreas Aloysius Henricus Duijmelink, Gerardus Wilhelmus Gerbe Van Dreumel

Publication number: 20130201690Abstract: Today the use of false ceilings is decreasing as it involves too high an energy consumption. The tendency nowadays is to have bare concrete ceilings onto which luminaires are mounted, which often causes acoustical problems. The invention deals with these acoustical problems and relates to an illumination device (1) comprising a concave reflector (2) bordering,with an outer edge (3),on a light emission window (4). The reflector has a reflective surface (7) facing the light emission window. The illumination device further comprises lamp holding means (8) for accommodating a light source (9),and said lamp holding means being positioned in between the reflective surface and the light emission window. The illumination device is characterized in that the reflector is made of acoustically absorbing material.Type: ApplicationFiled: September 19, 2011Publication date: August 8, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Michel Cornelis Josephus Marie Vissenberg, Antonius Petrus Marinus Dingemans, Marcus Jozef Van Bommel, Erik Paul Boonekamp

Publication number: 20130094240Abstract: The invention relates to an illumination device (1) comprising an optical waveguide (2) and a number of (connections for) light sources (3)—especially LEDs—positioned along the waveguide (3). This waveguide has a central axis (4) at a distance r to the surface of the waveguide, said surface comprising a light entrance surface (6) on which the (connections for) light sources are positioned and a curved light exit surface (5), wherein, viewed along the circumference of the curved surface (5), the distance r to a first intersection (8) between the flat surface (6) and the curved surface (5), changes to a second distance of different value at the second intersection (9) between said surfaces. The invention also relates to a luminaire comprising such an illumination device (1). Due to the special design of the waveguide (2), the amount of reflections of light in the light sources is largely reduced and desired shaping of the exiting beam can be realized.Type: ApplicationFiled: June 10, 2011Publication date: April 18, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Erik Paul Boonekamp, Willem Lubertus Ijzerman, Michel Cornelis Josephus Marie Vissenberg, Teunis Willem Tukker

Patent number: 6639342Abstract: The electric lamp employs a lamp vessel (1), which is transparent to visible light and which accommodates a light source (2). The lamp vessel (1) is covered with a combination of a light-absorbing medium (6) and an optical interference film (5) employing layers of alternately a first layer of a material with a comparatively high refractive index and a second layer of silicon dioxide. A spectral transmission T of light transmitted by the light-absorbing medium (6) changes from T≦0.15 to T≧0.75 in a wavelength range having a width &lgr;≦50 nm. The variation in reflection R amounts to less than 10% in the wavelength range 400≦R≦690 nm, the reflection R and lies in the range 50≦R≦90%. In operation, the electric lamp emits colored light in the transmission mode and has a substantially color-neutral appearance in the off state.Type: GrantFiled: June 13, 2001Date of Patent: October 28, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Erik Paul Boonekamp, Johannes Adrianus Frederikus Peek, Wolfgang Doetter

Patent number: 6570302Abstract: The electric lamp comprises a lamp vessel (11) which transmits visible light and which accommodates a light source (12). The electric lamp comprises a light-absorbing medium (16). The lamp vessel (11) is covered with an optical interference film (15) which comprises layers composed of a first layer of silica and a second layer of a material having a relatively high refractive index which alternate with each other. According to the invention, light from the light source (12) travels through the light-absorbing medium (16) before reaching the interference film (15). Preferably, the light-absorbing layer (16) is disposed between the lamp vessel (11) and the interference film (15). Alternatively, the light-absorbing layer is contained in a wall of the lamp vessel. Preferably, the interference film (15) reflects substantially in the same wavelength range as that wherein the light-absorbing medium (16) absorbs, preferably in the range from 570 to 620 nm.Type: GrantFiled: September 27, 2000Date of Patent: May 27, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Erik Paul Boonekamp, Mathias Hubertus Johannes Van Rijswick, Hendrik Adrianus Van Sprang, Gerhard Hebbinghaus
