Patent number: 8247973Abstract: A high intensity discharge light source includes an arc tube having a longitudinal axis and discharge chamber formed therein. The light source includes first and second electrodes having inner terminal ends spaced from one another along the longitudinal axis. Each electrode extends at least partially into the discharge chamber. The discharge chamber is deformed so that its internal geometry is substantially rotationally asymmetric about its longitudinal axis, and is substantially mirror-symmetric relative to a plane spanned by the longitudinal axis and by another transverse axis that is perpendicular to the longitudinal axis and is vertical in a horizontal arc tube orientation, as well as substantially mirror-symmetric relative to a central plane perpendicular to the longitudinal axis.Type: GrantFiled: June 3, 2010Date of Patent: August 21, 2012Assignee: General Electric CompanyInventors: Tamas Panyik, Agoston Boroczki, Istvan Csanyi, Csaba Horvath

Patent number: 8247960Abstract: A 3-dimension facet light-emitting source device including a transparent container, an anode plate, a cathode plate, a plurality of transparent plates and a low-pressure gas layer is provided. The transparent container has a sealed space. The transparent plates are disposed between the anode plate and the cathode plate, and have a fluorescent layer thereon respectively. The lower pressure gas layer is filled in the sealed space to induce electrons emitting from the cathode plate, and the electrons fly in a direction parallel to the transparent plates and hit each fluorescent layer to emit light, so as to form a set of 3-dimension facet patterns.Type: GrantFiled: April 30, 2010Date of Patent: August 21, 2012Assignee: Industrial Technology Research InstituteInventors: Po-Hung Wang, Yi-Ping Lin, Yen-I Chou, Ming-Chung Liu, Jung-Yu Li, Shih-Pu Chen, Jung-Ya Hsieh, Ta-Wei Chien

Patent number: 8227959Abstract: A metal vapor discharge lamp comprising an arc tube, an airtight tube housing the arc tube, and a base bonded to one end of the airtight tube with use of an adhesive, wherein the airtight tube is covered by a protective tube to improve safety as compared to a case where the protective tube is simply bonded to the base with an adhesive. The protective tube is fixed to the base with a double fall-off prevention structure, and latched to the base when a force including gravity and inertia acts on the protective tube toward the closed end of the protective tube in the axial direction thereof. The above-described structure eliminates the need of arranging the protective wall for securing the safety on the side of a lighting device on which the metal vapor discharge lamp is to be fixed, thereby preventing the lighting device from becoming large in size.Type: GrantFiled: November 19, 2010Date of Patent: July 24, 2012Assignee: Panasonic CorporationInventor: Shunsuke Kakisaka

Patent number: 8197096Abstract: A light source device includes a light source unit emitting light of a first wavelength and a wavelength converting element converting light of the first wavelength into light of a second wavelength. An external mirror transmits light of the second wavelength toward an emission destination and reflects light of the first wavelength to resonate between the light source unit and the external mirror. A wavelength separating section transmits light converted from the first wavelength to the second wavelength while traveling from the external mirror to the light source unit and reflects light of the first wavelength in order to separate the different wavelength light. A turnback section reflects light of the second wavelength separated by the wavelength separating section toward the emission destination. In addition, the wavelength separating section reflects light of the first wavelength from the light source unit to travel toward the wavelength converting element.Type: GrantFiled: May 16, 2011Date of Patent: June 12, 2012Assignee: Seiko Epson CorporationInventor: Shunji Kamijima

Patent number: 8188664Abstract: A compact mercury-free high intensity discharge (HID) lamp particularly suitable for automotive headlamp application has a pair of spaced and opposing electrodes sealed in a transparent enclosure defining an arc chamber. An outer transparent envelope has a first and second textured light scattering stripe on its interior surface on substantially opposite sides thereof extending continuously from one electrode to the other. The stripes widen the cross-sectional luminance distribution of the arc discharge image and make the image of the arc straighter while keeping light scattering losses at minimum so that the reduced arc peak luminance is still at the desired level. In other versions, a plurality of textured light scattering stripes of smaller widths are employed to replace a single wider light scattering stripe.Type: GrantFiled: November 16, 2010Date of Patent: May 29, 2012Assignee: General Electric CompanyInventors: Agoston Boroczki, Csaba Horvath, Istvan Kapas

Patent number: RE45342Abstract: In order to achieve a discharge lamp suited to operate under reduced nominal power of e.g. 20-30 W, a lamp is proposed with two electrodes (24) arranged at a distance in a discharge vessel (20, 120) for generating an arc discharge. The discharge vessel (20,120) has a filling with a substantially free of mercury and comprises a metal halide and a rare gas. The lamp (10, 110) further comprises an outer bulb (18) arranged around the discharge vessel at a distance (d2). The outer bulb (18) is sealed and has a gas filling of a thermal conductivity (?). The inner diameter (d1) of the discharge vessel is preferably in a range from 2-2.7 mm. The wall thickness (w1) is in a range from 1.4-2 mm. A heat transition coefficient (?/d2) is calculated as thermal conductivity (?) at 800° C. of the outer bulb filling divided by the distance (d2). The so-defined heat 10 transition coefficient is below 150 W/(m2K).Type: GrantFiled: September 13, 2013Date of Patent: January 20, 2015Assignee: Koninklijke Philips N.V.Inventors: Michael Haacke, Martin Stroesser
