A fluorescent lamp 1 comprises: a bulb 2 formed by heating bent-portion-formation preordination portions of a single straight-tube-shaped bulb 2a having an external tube diameter of 12 to 20 mm and a tube length of 800 to 2500 mm, forming a plurality of bent portions 2c and straight tube portions 2b adjacent to the bent portions 2c by bending processing, such that the straight portions 2b are disposed generally within the same plane by way of the bent portions 2c, forming in close proximity a pair of end portions 2d and 2d with electrodes 5 and 5 sealed in so as to form a single discharge path through the straight tube portions 2b and bent portions 2c, forming a phosphor layer 4 on the inner face of the bulb, and sealing a discharge medium including mercury; and a base 6 provided on the end portions 2d and 2d of the bulb 2; whereby thermal deterioration of the phosphor layer 4 formed at the straight tube portions 2b is reduced so deterioration of the initial light flux is suppressed, allowing lighting at higher efficiency. According to the above configuration, a fluorescent lamp which is compact and capable of light with high efficiency, and with improved light output properties, and a light fixture using this fluorescent lamp, can be provided.

The present invention is directed to a method for forming glass articles containing enclosed channels. The method comprises the flollowing steps: a) delivering and depositing a first length of a molten glass ribbon (18) to a surface of a mold (20) having a modl cavity (22) possessing at least one channel-forming groove (22) and a peripheral surface, wherein the first length (18) overlies the mold cavity (22) and the peripheral surface; b) allowing the first length of the molten glass ribbon (18) to substantially conform to the contour of the mold cavity (22) resulting in the formation of at least one channel in the first length of the molten glass ribbon (18); c) delivering and depositing a second length of the molten glass ribbon (26) to the exposed surface of the first length of the molten glass ribbon (18). The delivered molten glass viscosity of the molten glass ribbon (18, 26) is such that the following is achieved: 1) the second length (26) bridges but does not sag into complete contact with the channel portion of the earlier-deposited first length (18); and, 2) a hermetic seal is formed wherever the molten glass' first (18) and second lengths (26) contact.

The invention relates to a flat spotlight (1) with a closed, gas-filled discharge vessel (2) and enclosing band-shaped electrodes separated from the discharge by a dielectric layer. The discharge vessel (2) consists of at least one base plate (5) and one cover plate (6) which are assembled by soldering (8) so as to be gastight, and optionally, also by means of an additional frame (7) placed between the cover and base plate. In addition, the band-shaped internal electrodes (3, 4) verge into passages (10, 11), and these passages verge into external power leads (12, 13) in such a way that the internal electrodes (3, 4), the passages (10, 11) and the external power leads (12, 13) are respectively conceived as functionally different sections of structures (3, 10, 12; 4, 11, 13) of the printed conductor type on the cathodes and/or anodes. At least the anodes (4) are respectively coated with a dielectric layer (17). The passages (10, 11) are, in addition, optionally covered by the soldering (8) so as to be gastight.

摘要:
A flat planar fluorescent lamp having barrier structures overlaying the electrodes is described. The barrier structures include barrier walls and platforms between the electrodes and the lamp cover with passageways between the platforms and the lamp cover. The barrier structures cause the electric discharge between the lamp electrodes to pass between the platforms and the lamp cover. The interior of the lamp and the top of the platform are coated with a fluorescent material such that the lamp produces light throughout its interior, including the region directly above the electrode, thereby providing a source of light in an area which would otherwise be a dark region surrounding the electrode. In one embodiment, a cold electrode, a hot electrode, an ion barrier, and a tubulation are formed in a glass seal as a single unit, placing the terminals of the electrodes and the tipped-off tubulation in a small region of the lamp to permit easier access and alignment. Two tubulations are used to permit the lamp to be pumped at locations adjacent the two electrodes to reduce problems associated with free ions in the region around the electrode. In one embodiment, a metal lamp body having an insulative coating and including an integral barrier structure is formed using conventional metal stamping techniques. In another embodiment, the lamp body is formed from glass which is shaped according to known techniques to form an integral barrier wall. The platform is then attached to the integral barrier wall and supported at its sides by ledges formed in the sidewall and channel wall of the lamp.
