Embodiment Construction

[0027] Embodiments of the present invention will be described below with reference to the drawings.

[0028] The bulb-type fluorescent lamp of the first embodiment of the present invention with a rated power of 13W has an overall length of 120 mm and a maximum outer diameter of 60 mm. Such as figure 1 As shown, in a peripheral device formed by a light-transmitting glass shell 1 and a resin tube shell 2, a fluorescent tube 4, which is bridged by three U-shaped tubes 3 with an outer diameter of 11mm to form a discharge circuit, is installed. A lighting circuit 5 for lighting the tube 4 , and a holder 6 that holds one end of the fluorescent lamp 4 and holds the lighting circuit 5 on the opposite side of the fluorescent tube 4 .

[0029] At one end of the case 2, a socket portion 7 to be inserted into a base (not shown) of a lighting fixture is formed. The socket part 7 has an eyelet 8 and a base 9 which are in electrical contact with the base. Furthermore, an eye socket porti...

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 (2) having a shell (9) at an end thereof, and a lighting circuit (5) housed in the case (2) and having a printed circuit board (12) with a circuit part (13) mounted thereon, wherein the shell (9) and the lighting circuit (5) are connected together without leads.

Description

technical field [0001] The present invention relates to tubular lamps and methods for their manufacture. Background technique [0002] Conventional tubular lamps such as light bulb fluorescent lamps such as Figure 16 Shown, be that the lighting circuit 38 that fluorescent tube 4 and this fluorescent tube lighting usefulness are housed in the peripheral device that is made of glass bulb 1 and tube shell 37. [0003] A socket 41 having an end eye 39 and a lamp cap 40 is screwed to one end of the tube shell 37 . [0004] The lighting circuit 38 has two lead wires 42 and 43 for power supply. A wire 42 is drawn out from a through hole 44 provided on the terminal eye 39, and is soldered and connected to the outside of the terminal eye 39 with solder as an electrical connection. [0005] Another wire 43 is drawn out of the tube shell 37, and is electrically connected to the outside of the lamp holder 40 by soldering. [0006] However, this conventional tubular lamp is connected...
