Abstract: To provide a bulb-type lamp in which a globe is fixed to a case without a tilt, and a manufacturing method for the bulb-type lamp. The globe is bonded to a connector using a thermosetting resin, in a state where a neck part of the globe is inserted in a groove of the connector without contacting the bottom of the groove. The connector is then fixed to the case by means of a fitting construction. This makes it unnecessary to perform a heating process to cure an adhesive after an envelope is formed by the globe and the case. Hence the tilting of the globe caused by the thermal expansion of air in the envelope can be prevented.

Abstract: A bulb-type fluorescent lamp has a case having an open end portion for housing a lighting circuit therein, an arc tube extending outside through the open end portion of the case, and a globe having an open end portion for housing the arc tube therein. An adhesive is supplied to the inner surface of the open end portion of the case at four circumferentially spaced areas, and the open end portion of the globe is inserted into the open end portion of the case. As a result, the globe is fixed to the case with the adhesive.

Abstract: A lampholder for receiving a cap of a lamp includes a body, a receiving portion, and lead wires: the receiving portion is provided in the body and to be connected to the cap; the lead wires are connected to the receiving portion. The receiving portion is made of conductive resin. This configuration can reduce the parts, simplify assembly, lower the cost, and improve the productivity.

Abstract: The present invention provides a tube lamp and its manufacturing method which allow a lighting circuit and a shell to be easily and reliably connected together, which enable automation of a step of connecting the lighting circuit and the shell together, and which require low costs while achieving a high production efficiency. The tube lamp includes a case having a shell at an end thereof, and a lighting circuit housed in the case and having a printed circuit board with a circuit part mounted thereon, wherein the shell and the lighting circuit are connected together without leads.
