Abstract: A junction component fixed on a PCB (13) has a slot (4) suitable for accepting the electrical leads (10) protruding from the electrical unit and also has a base part (11) and a connection part (12). The base part (11) is embedded into the PCB (13) and is connected with its corresponding output. The leads of the electrical unit are connected to a connection part (12). At the place of connection, the orientation of the electrical leads is substantially perpendicular to the plane of the PCB (13). The direction in which the electrical leads are connected to the connection part (12) is substantially parallel to the plane of the PCB (13). The base part (11) comprises a base plate (1) and tabs(s) (8a-8c) bending out from it. The tab(s) protrude(s) into openings (17) formed in the PCB (13) and is (are) embedded there in a way also ensuring electrical contact to the PCB (13).

Abstract: A fluorescent lamp includes a lamp tube having first and second ends and containing fill materials for causing light generation when provided with electrical power. The lamp further includes first and second power-transferring means at the first and second ends of the lamp tube, respectively, for providing the fill materials in the lamp tube with electrical power. Also included is a thermal heat shield separating the first power-transferring means from ballast circuitry which supplies power to the first power-transferring means and which has a lifetime that becomes substantially less as its operating temperature increases. The thermal heat shield is constructed so that it reflects back to the first power-transferring means and any adjacent portion of the lamp tube sufficient radiant energy to reduce the operating temperature of the ballast circuitry by more than about one degree Celsius compared with the absence of the heat shield.

Abstract: 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.
