Abstract:
An electric discharge lamp includes a light transmissive inner jacket that defines a sealed inner chamber, a first material in the inner chamber that emits light when activated, and a light transmissive outer jacket around the inner jacket. The outer jacket defines a sealed outer chamber between the inner and outer jackets that contains a second fill material. The second fill material, when activated by heat from the inner chamber when the lamp is operating, converts ultraviolet (UV) and deep blue light emitted from the inner chamber to visible light, thereby increasing an amount of visible light transmitted through the outer jacket compared to an amount of visible light transmitted through the inner jacket.
Abstract:
A planar fluorescent lamp equipped with a pair of flat electrodes and a method for fabricating such lamp are disclosed. In the planar fluorescent lamp, a lamp housing and a cover plate which are both formed of a soda-lime glass can be bonded together to form a vacuum tight seal by glass frit. A pair of flat electrodes and a pair of getter strips are pre-mounted in the cavity of the planar lamp. The pair of flat electrodes run substantially the full width of the interior cavity of the lamp such that a substantially uniform electric discharge field can be formed in the cavity when a RF power is supplied to the electrodes. A bottom panel of the lamp housing may be fabricated in a ribbed structure to improve the rigidity of the bottom panel such that it does not bow in when the cavity is sealed under a vacuum pressure.
Abstract:
A fluorescent lamp comprises a discharge tube disposed substantially in a plane and shaped at least in part to define a substantial portion of the boundary of a zone in the plane. The part of the tube defining the boundary includes at least one straight portion. The discharge tube has a central axis and sealed ends provided with electrodes and at least two tube sections running substantially parallel to each other. Each tube section has at least one blind-sealed end and the tube sections are connected in series through bridges in the vicinity of the blind-sealed ends to define a single continuous discharge space to be excited by electrical power supplied to the electrodes. A lamp support housing is positioned within the zone and the ends of the discharge tube as well as the blind-sealed ends of the tube sections are re-entrant into the zone. The ends of the discharge tube are received in the lamp support housing. The lamp support housing carries means suitable for mechanically and electrically connecting to a socket and include lead-in wires connecting the electrodes directly or through an operating circuit to the means suitable for electrically connecting to a socket.

An envelope includes a face plate, a rear plate arranged so as to be opposite to the face plate, an outer frame arranged between the face and rear plates and surrounding a circumference, and a face plate joining portion for joining the outer frame and the face plate. A rear plate joining portion joins the outer frame and the rear plate to each other, with one or both of the face plate joining portion and the rear plate joining portion including a sealant having a seal function and an adhesive having an adhesive function.
Abstract:
The present invention is directed towards a thin, flat glass envelope having an enclosed, internal channel and a molded edge for affixing attachments directly to the glass envelope. Suitable attachments include filters, i.e., diffusion, polarizing, glare reducing, brightness enhancing, liquid crystal display screens and masking components. The channeled envelope has a front and a back surface laminated and integrated together to form a unitary body essentially free of any sealing materials. A lightweight, light-emitting device or low-pressure discharge lamp can be formed from this channeled envelope, suitable for employment in the fields of LCD backlighting, automotive lighting, and general lighting.
Abstract:
An electromagnetic-wave shielding and light transmitting plate is formed by two transparent base plates, a conductive mesh member, and a near infrared ray blocking film, wherein the conductive mesh member and the near infrared ray blocking film are interposed between the transparent base plates and are integrally bonded together. A panel laminated plate is formed by a transparent base plate, a PDP body, a conductive mesh member, and a near infrared ray blocking film, wherein the conductive mesh member and the near infrared ray blocking film are interposed between the transparent base plate and the PDP body and are integrally bonded together. Either in the above electromagnetic-wave shielding and light transmitting plate or in the panel laminated plate, the near infrared ray blocking film is a combination of two or more of near infrared ray blocking layers.

Abstract:
An electrodeless gas discharge lamp includes a light-transmissive envelope having opposite ends and a midsection about which an induction coil is disposed. The envelope and coil are mounted transversely on a base with the ends of the envelope exposed such that light emitted from the envelope is transmitted through both ends of the envelope substantially unobstructed by either the base or coil to generate a high total light output of the assembly.
Abstract:
This invention provides a photocatalytic membrane and a lamp and lighting fixture using such a membrane. The membrane is formed using an ultra fine particle dispersed liquid coating method providing improved adhesion of the membrane to a base body and provides a photocatalyzer that has a satisfactory light transmission factor and a lamp and a lighting fixture using it. The membrane is made of mainly ultra fine particles of titanium oxide, which enter into the uneven surface portions of a ground layer and are closely fitted thereto via the ground layer made of a metallic oxide with an uneven surface formed on the surface is formed on the base body. When the ground layer is made of metallic oxide and porous, the uneven surface is formed on the surface of the ground layer. Concave portions of the ground layer may be penetrated to the surface of the base body or a metallic oxide structural layer provided with a lot of penetrating holes may be formed on the surface of a photocatalytic membrane. Silicon oxide, titanium oxide and aluminum oxide are usable as a metallic oxide.
