Problems solved by technology

[0011] This shows that the above-mentioned existing bulb-shaped fluorescent lamps and lighting fixtures obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve

Embodiment 1

[0078] The structure of this embodiment uses a light bulb-shaped fluorescent lamp with a spiral curved lamp tube and is equivalent to a 100W incandescent bulb, and a downlight (down light)-shaped lighting fixture using this lamp. The structure of the luminous tube will be explained.

[0079] Such as figure 2 As shown, the arc tube 1 is composed of a glass curved tube 2 provided with a pair of bulb ends, and includes a spiral portion 10 and electrode sealing portions 20, 20' formed at both ends of the tube.

[0080] The spiral portion 10 is a straight circular tube with an outer diameter of about 10 mm formed of transparent lead-free glass, which is bent approximately in half in the length direction of the lamp tube. The approximate center of the straight tubular member is the top 10a, and the both ends of the lamp tube are wound on a forming jig not shown, bent into a helical shape, and molded into a substantially cylindrical double helical shape.

[0081] In addition, both...

Abstract

The invention relates to the bulb-shape fluorescent lamp and an illuminating device which can guarantee the stated position of the lateral lamp opening at the amalgam position sealed in the thin tube by a simple method. The bulb-shape fluorescent lamp of the invention comprises a light-emitting tube having a bending lamp tube; a lightening device for lightening the lamp tube; a cover component having a supporting component of the light-emitting tube and being provided with a lightening device; a lamp opening provided on the cover component; a thin tube provided as protruding from the end part of the light-emitting tube to the inner side space of the lamp opening; and an amalgam closer to the inner wall side than the axial central x-x provided in the inner space of the lamp opening.

Description

technical field [0001] The present invention relates to a bulb-shaped fluorescent lamp and a lighting fixture, in particular to a bulb-shaped fluorescent lamp and a lighting fixture that can replace conventional light bulbs for general lighting. Background technique [0002] A lightbulb-shaped fluorescent lamp is known in which a cover member is provided on a socket (ferrule) which can be mounted on a socket (socket) of a general lighting bulb such as an incandescent bulb, and a glass glass is mounted on the cover member. A bulb is a luminous tube and a lighting device formed by bending a bulb, and the luminous tube is covered with a globe. [0003] In recent years, the miniaturization of such bulb-shaped fluorescent lamps has progressed and spread widely, and further miniaturization and higher output have been achieved, and improvements in lamp efficiency and strong light beams after lighting have been demanded. [0004] In order to meet the above requirements, it has been...
