摘要:
A dielectric barrier discharge lamp comprises multiple tubular discharge vessels of a substantially equivalent size and having a principal axis. Each discharge vessel encloses a discharge volume filled with a discharge gas. The discharge vessels are arranged substantially parallel to their principal axis and adjacent to each other. The lamp also comprises a first set of interconnected electrodes and a second set of interconnected electrodes. The electrodes are isolated from the discharge volume by at least one dielectric layer. At least one of the dielectric layers is constituted by the wall of the discharge vessel, and the electrodes of at least one electrode set are located between the discharge vessels. In one embodiment, the discharge vessels are adjacent to each other in a lattice, and the first and second electrode sets are located between the discharge vessels in interstitial voids of the lattice. In another embodiment, the discharge vessels are arranged adjacent to each other along generatrices of a prism.

A dielectric barrier discharge (DBD) lamp is disclosed. The DBD lamp comprises a discharge vessel, which encloses a discharge volume filled with discharge gas. The discharge vessel further comprises a phosphor layer within the discharge volume. The discharge vessel comprises an outer tubular portion having an internal surface, and an inner tubular portion having an outward surface. The outer tubular portion surrounds the inner tubular portion. In this manner, a substantially annular discharge volume is enclosed between the outer tubular portion and the inner tubular portion. The inner tubular portion comprises a multitude of protrusions around its circumference. The protrusions extend into the substantially annular discharge volume. A first set of interconnected electrodes and a second set of interconnected electrodes are also provided. The electrodes are isolated from the discharge volume by at least one dielectric layer, and at least one of the dielectric layers is constituted by the wall of the inner tubular portion.

The invention relates to the discharge tube of a compact fluorescent lamp which discharge tube, being sealed hermetically and provided with appropriate fill, comprises at least two tube portions connected with each other, and electrodes are placed at the ends of the first and last tube portions, and lead wires protrude through the glass wall of the discharge tube to the electrodes. The invention also relates to a method for closing at least one of the tube portions forming a part of the discharge tube of a compact fluorescent lamp. The essential feature of the discharge tube according to the invention is that at least one of these tube portions is closed by a curved surface having tangents which, starting from the axis of the tube portion and extending to the cylindrical wall thereof, make a monotonously decreasing angle with the axis of the tube portion.

A bulb-shaped outer envelope for accommodating at least one lamp including a light-emitting body and a control gear is disclosed. The envelope has a substantially spherical section for receiving the light-emitting body, and an elongated end section for receiving at least a part of the control gear components. The elongated end section is provided with a neck section. A substantially tubular neck-extension portion connects to an inner surface portion of and protruding from the neck section. The neck-extension portion is suitable for accommodating a remaining part of the control gear components. In a method for the manufacture of a glass outer envelope, a flare that is normally used in the manufacture of incandescent lamps is turned around by 180°, put into a skirted bulbous envelope, melted into the envelope while the skirt is detached and the flare is formed into a neck-extension portion. A self-ballasted compact fluorescent lamp with the bulb-shaped outer envelope is also disclosed. A part of the ballast components are disposed in the neck-extension portion of the outer envelope.

A dielectric barrier discharge lamp is disclosed, which has a discharge vessel enclosing with a wall a discharge volume filled with discharge gas. There is a phosphor layer within the discharge volume. The discharge lamp comprises first and second sets of interconnected electrodes, which are isolated from the discharge volume by at least one dielectric layer. At least one of the dielectric layers is the wall of the discharge vessel. Both the first and second sets of electrodes are located external to the discharge vessel. Advantageously, the discharge vessel comprises an outer tubular portion with an internal surface and an inner tubular portion with an outward surface. The outer tubular portion surrounds the inner tubular portion, and the discharge volume is enclosed between the internal surface of the outer tubular portion and the outward surface of the inner tubular portion.

A cap for securing a plurality of discharge tubes to a discharge lamp assembly includes a pair of ribs formed on a base plate of the cap. The ribs guide adhesive towards openings in the base plate through which the tubes extend. Adhesive is kept away from the base plate perimeter, which may include a rim, such that assembly of the cap with a housing does not upset the adhesive bond securing the discharge tubes to the cap. Similarly, an assembly method for the cap involves the step of forming a pair of ribs on the base plate of the cap.

The cap according to the invention has a base plate and a side wall and in the base plate, openings are formed for accepting the glass body or bodies of the lamp envelope. Optionally, a partition is placed between the side wall and these openings. The essential feature of the invention is that the cap has, in its inner space bordered by the side wall, or optionally by the partition, components extending to at least one opening and bordering a smaller space at its side, the smaller space being intended to accept an adhesive and is also bordered by some portion of the base housing.
