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.

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.

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 discharge lamp has a discharge tube filled with a fill gas and sealed in a gas-tight manner and a cap part made to be suitable for connection to a socket. This cap part has a housing made by a shell and a closing member fixed thereto, and electrical contact components. The shell has openings for receiving the end portions of the discharge tube legs into the housing and the shell is made to be suitable for supporting the discharge tube mechanically. The electrical contact components are embedded in the housing and connected in the inner space of the housing to the electrodes of the discharge lamp and protrude from the cap part. The cap part contains mechanical support component(s) for fixing the discharge lamp in the socket. The mechanical support component(s) forms (form) a part of the shell and the portions of the electrical contact components protruding from the cap part are placed in an outwardly open indentation defined by an indented plate portion of a bordering plate of the cap part, preferably of the base plate of the closing member.

The invention relates to a single-ended discharge lamp with circuitry in its housing base. The discharge lamp includes a discharge tube and a housing. The discharge tube is provided with electrodes containing a fill and sealed in a gas-tight manner. The housing base contains circuitry mounted on a circuit board and providing for the operation of the discharge tube. The housing base is built from two parts, a base and a cap, fixed to each other. The housing base is formed in a way suitable for mechanical and electrical connection to a lamp socket on one part, and for mechanically fixing the discharge tube and connecting the output terminals of the circuitry to the electrode inleads of the discharge tube on the other part. The circuit board is inserted between supports formed in the inside of and protruding from one part of the housing base. One feature of the invention is that longitudinal ribs are formed on the support and protrude from the support. The ribs are so dimensioned that in the direction of insertion of the circuit board, the space available for the circuit board progressively decreases, which results in the circuit board moving up to a stop on the ribs over at least a part of the length thereof.

The invention relates to a single-ended discharge lamp having a lamp envelope comprising at least two tube legs, and a housing portion designed for mechanical and electrical connection to a lamp socket, which housing portion consists of a tube supporting part, a connection part and a screw base, which parts are linked together. Holes are made in the tube supporting part into which holes the legs of the lamp envelope are placed and the ends of the legs of the lamp envelope being inside the housing portion are fixed with a bonding material applied to the outside lamp envelope portion of the tube supporting part which portion surrounds the lamp envelope. The essential feature of the invention is that the ends of the tube legs of the lamp envelope being inside the housing portion are fixed to the tube supporting part with a bonding material being also applied to the inside portion of the tube support part, which inside portion is bordered by the tube legs.

An outer envelope for accommodating at least one light-emitting body and a control gear with electrical components is suggested, the outer envelope comprises a wall at least partially of a glass material, in which the glass wall of the outer envelope is covered with a coating of powder varnish of poly-ester-blocked isocyanate for uniform spherical luminous intensity distribution, protecting the envelope against mechanical shocks and providing for shatter containment. A lamp with an outer envelope for accommodating at least one light-emitting body and a control gear with electrical components is also suggested.An improved compact fluorescent lamp comprises a discharge tube arrangement, a ballast circuit, a base and a substantially bulb-shaped outer envelope. The substantially bulb-shaped outer envelope has a wall at least partially of a glass material, and comprises a substantially spherical portion enclosing at least a part of the discharge tube arrangement and an elongated end portion enclosing at least a part of the ballast circuit. The glass wall of the outer envelope is covered with a coating of powder varnish of polyester-blocked isocyanate for uniform spherical luminous intensity distribution, protecting the envelope against mechanical shocks and providing for shatter containment.

A single-ended low pressure discharge lamp having an Edison base includes at least one U-shaped fluorescent tube having electrode leads which are connected to a ballast arrangement disposed in a housing base. The housing base has an upper part on which the fluorescent tubes are mounted, a connecting part on which a threaded base is mounted and a supporting part formed between the upper part and the connecting part. Lead-in wires are connected from the ballast arrangement to the threaded base in a manner to facilitate automated assembly of the lamp. A first lead in wire connects to the central portion of the threaded base whereas a second lead-in wire connects to the sleeve portion after first passing through a guided opening formed in the housing base between the supporting part and the connecting part.
