Abstract: A fluorescent lamp device with an incandescent bulb type base cap is disclosed. The fluorescent lamp device has a luminous tube unit (1) and a case (3) with one end supporting the luminous tube unit (1), and the other end has an outwardly projecting portion (2). A ballast (8) is provided in the case (3), and a base cap (4) is adapted to be rotatably fitted to the projecting portion (2) of the case. The outer periphery of the projecting portion (2) of the case has an engagement groove (6) formed in it and a stopper portion (7) which is formed in the axial direction of the case. An engagement portion (11), a guide groove (12) and a rotation limiting groove (14) having a rotation stopper portion (13) are successively provided for the inner surface at one end of the base cap disposed in that order starting from the one end of the base cap. By fitting the engagement portion (11) of the base cap in the engagement groove (6) of the case, fitting one end of the projecting portion (2) of the case in the guide groove (12) of the base cap, fitting the stopper portion (13) of the base cap in the rotation limiting groove (14) of the base cap, and rotating the stopper portion (7) so that it is fitted in the rotation limiting groove (14), the luminous tube unit and the case can be rotatably fitted to the base cap, and rotation of the stopper portion (7) can be prevented by the rotation stopper portion (13).

Abstract: 1,202,505. Discharge lamps. MATSUSHITA ELECTRONICS CORP. 25 Feb., 1969 [1 March, 1968: 30 May, 1968; 21 June, 1968; 30 Aug., 1968; 13 Sept., 1968], No. 9972/69. Heading H1D. [Also in Division H2] A fluorescent lamp 1 rated at 10 watts comprises an elongated glass envelope having an outer diameter of 25 mm., the envelope being filled with a mixture of mercury and argon and a phosphor coating applied to the inner surface of the envelope. The cathode 2 and anode 3 of the lamp may both be of the wound filamentary type but the anode may alternatively be in the form of two rod-like electrodes 3, 3 1 having a spacing therebetween of 5 mm.
