Problems solved by technology

However, since the sphere is made of glass, not only is it difficult to form a stopper for the sphere, but it may also come off when engaged with the stopper accommodating portion
For this reason, spherical fluorescent lamps of this type are not practical

[0048] Referring to the drawings, a first embodiment in which the present invention is applied to a spherical fluorescent lamp will be described.

[0049] (Structure of a spherical fluorescent lamp)

[0050] figure 1 is a partially cutaway front view of the spherical fluorescent lamp of the first embodiment. figure 2 It is an expanded view of a spherical fluorescent lamp.

[0051] This spherical fluorescent lamp is rated at 13w. Such as figure 2 As shown, the spherical fluorescent lamp has a spherical unit 1 , a shell unit 2 and an arc tube unit 3 . The arc tube unit 3 accommodates a fluorescent tube 31 and is enclosed in a lamp envelope formed by the spherical unit 1 and the housing unit 2 .

[0052] The ball unit 1 includes a ball 10 and a joint 11 which is adhered to the edge portion 10b with an adhesive at the open end of the ball 10 .

[0053] The sphere 10 is made of pear-shaped glass with an opening 10a. A narrow constriction 10c is formed near the opening 10a...

Abstract

The present invention relates to a spherical lamp in which a spherical body is fixed to a housing without inclination, and a manufacturing method for the spherical lamp. In a state where the neck of the sphere is inserted into the groove of the joint without contacting the bottom of the groove, the sphere is bonded to the joint with a thermosetting resin. Then, use the mating structure to secure the connector to the housing. This eliminates the need for a heating process to harden the adhesive after forming the enclosure with the sphere and housing. Thus, tilting of the sphere caused by thermal expansion of the air in the enclosure can be prevented.

Description

technical field [0001] The present invention relates to spherical lamps having a spherical body, such as spherical fluorescent lamps and electrodeless discharge lamps, and methods for their manufacture. Background technique [0002] A globe lamp is a lamp in which a spherical sphere is fixed to the housing, as used in incandescent lamps. Examples of such spherical lamps include spherical fluorescent lamps and electrodeless discharge lamps. The sphere is made of glass, taking into account the heat generated in the lamp. In addition, the ball is fixed to the case with an adhesive made of thermosetting resin such as silicone resin, which has excellent heat resistance and sealing ability. [0003] Taking a spherical fluorescent lamp as an example, the structure of the spherical lamp and the method for fixing the spherical body to the housing will be described below. [0004] Figure 10 is a partial sectional view of a conventional spherical fluorescent lamp. [0005] The sph...
