1 is a partially cutaway front view of an annular fluorescent lamp according to a first embodiment of the present invention, FIG. 2 is an enlarged cross-sectional view of an essential part of FIG. 1, FIG. 3 is an external perspective view of the detention of FIG. 1, and FIG. 4 is a detention of FIG. 5 is a bottom view of the cap of FIG. 1, and FIG. 6 is a front view of the cap of FIG. 1.

As shown in FIG. 1, the annular fluorescent lamp 1 is comprised, for example by attaching the shackle 3 to the multi-ring valve 2. As shown in FIG.

The multi-ring valve 2 has a concentric shape on the inner side of the outer annular valve 2A, which is made of glass, and the inner annular valve 2B, which is similar in shape, to the inner annular valve 2B. Iv), and the outer annular valve 2A and the inner annular valve 2B are integrally connected by the connecting portion 2C, thereby forming a single discharge path.

These inner and outer annular valves 2A and 2B are each formed in, for example, almost square in one plane by bending of one straight pipe glass valve 2A1 and 2B1, for example. It is formed in a similar form and has a plurality of straight pipe portions s, ..., and a plurality of bent portions c, .... In these inner and outer annular valves 2A, 2B, the respective axial end portions 2A2, 2A3, 2B2, and 2B3 are disposed to face substantially concentrically at intervals of the required intervals. On the outer surfaces of the ends 2A2, 2A3, 2B2, and 2B3 of these inner and outer annular valves 2A and 2B, hollow detentions 3 are formed at both ends 2A2 and 2A3 and 2B2. It is fitted from the outside so as to span between and 2B3.

The pipe outer diameter of each straight pipe portion S of the inner and outer annular valves 2A and 2B is, for example, in a range of 12 to 20 mm. The optimum range of the tube outer diameter of each straight pipe portion s when considering lamp characteristics such as lamp efficiency and manufacturing conditions is 14 to 18 mm. In addition, although the straight pipe | tube part s near the bend part (c) changes a pipe outer diameter a little in the bending process of the curved part (c), it can be considered that it partially departs from the said range, In the case of this invention, the straight pipe part (s) Most of these should just be in the said range. In addition, the thickness of the straight pipe portion s is preferably about 0.8 to 1.2 mm.

The foreign exchange valves 2A and 2B are formed of soft glass such as soda lime glass or barium silicate glass, but may be semi-hard glass such as borosilicate glass. The thickness of the valve is preferably about 0.8 to 1.2 mm, but is not limited thereto.

The pipe length of the multi-ring valve 2 is mainly connected to the plurality of annular glass valves by the connecting portion 2c so that a single discharge path is formed. It is influenced by design factors such as external size and rated lamp power of an annular fluorescent lamp. Therefore, by appropriately selecting the tube length of the multi-ring valve 2 from the range of 800-3000 mm, the most suitable polycyclic fluorescent lamp for general illumination can be obtained. In addition, a pipe length is the dimension along a pipe axis.

In addition, in the present invention, in the present invention, the distance between the bent portions c of the inner and outer annular valves 2A and 2B forming an adjacent pair is defined as a maximum distance of 6 to 15 mm. have. However, when the distance is less than 6 mm, the radius of curvature of the bend portion c becomes too small, which makes it difficult to bend the valve.

It is also used when the inside of the multi-ring valve 2 is evacuated or the discharge medium is sealed, and the tip is turned off after the discharge medium is sealed. The discharge medium is composed of mercury and argon (Ar), and is formed inside the multi-ring valve 2 via the tubules 5g and 6g after forming the multi-ring valve 2. In addition, the capillaries 5g and 6g are chipped off after the discharge medium is sealed. The inner lead wires 5b and 5c, 6b and 6c and the outer leads 5d, 5e, 6d and 6e are connected via a dummet wire J which is airtightly embedded in the flare stems 5a and 6a. It is.

Next, the receiving member of the caulking jig which is not shown from the upper side of each of the detention pins 7c shown in FIG. 7 is inserted. Thereafter, a caulking punch (not shown) is inserted from the communication grooves 7i and 7j on the left and right sides of each of the detention pins 7c to pressurize it, and the end portion of each detention pin 7c is caulked by accommodating this into the housing member. As a result, as illustrated in FIG. 2, the outer leads 5d, 5e, 6d, and 6e are electrically and mechanically connected to the respective pins 7c. Thereafter, the protrusion ends of the outer leads 5d, 5e, 6d, and 6e that protrude outward from the front ends of the respective pins 7c are removed.

Next, the opening end of the second detention member 8 is fitted on the opening end of the first detention member 7 and pushed toward the first detention member 7 side.

Then, the four engaging pieces 7p,... Of the first detaining member 7 and the four engaging passage holes 8n,... Of the second detaining member 8 engage, and are paired in two. The bottom coupling recesses 7m and 7n and two pair of coupling protrusions 8i and 8i are assembled to form the cage body 3o.

In this way, the first detention member 7 and the second detention member 8 are coupled, and after being assembled to the detention apparatus 3, as shown in FIG. 3, the left and right sides (multiple) of the detention pins 7c,... On the inner and outer sides of the ring valve 2, a pair of engaging projections 8c and 8d of the second detaining member 8 protrude upward from the bottom portion 7b in the drawing to form a side wall, and the detention pins The pair of communication grooves 7i and 7i on the side of 7c are closed.

Thereby, the pin which surrounds the four sides of each of the detention pins 7c of a rectangular arrangement by a side wall.

A recess 7a is formed. For this reason, this pin recess 7a is only opened upward in FIG. 3, and since the opening area is reduced, foreign matter penetrates into the pin recess 7a from this opening, Deformation or damage can be reduced.

And since the detention pin 7c is provided in the pin recess 7a, the socket hole 11a and the detention pin which were provided in the base 11c of the socket 11 which fits in this pin recess 7a are provided. The ease and certainty of fitting of 7c) can be improved.

Moreover, in the state in which the detention pin 7c is fitted in these socket hole 11a, each V-shaped locking end part 11da, 11ea of the pair of V-spring 11d, 11e as a coupling means of the socket 11 is carried out. Guided to the coupling vertical grooves 8j and 8k formed in the pair of locking projections 8c and 8d of the cage 3, the cage 3 is caught by the coupling ends 8l and 8m, thereby restraining the cage 3 to the environment of the valve. Since it is elastically clamped in the direction, the detention 3 is simply and reliably mounted to the socket 11.

Further, as shown in FIG. 6, the pair of locking projections 8c and 8d of the second prison member 8 are projected toward the first prison member 7 side, so that the locking protrusions 8c and 8d are locked. The end parts 8l and 8m can be provided in the vicinity of the joining line of the 1st holding member 7 and the 2nd holding member 8.

Coupling portion, in which the respective V-shaped locking ends 11de and 11ea of the pair of V-springs 11d and 11e of the socket 11 engage the locking ends 8l and 8m, has a width in the axial orthogonal direction of the cap 3 By locating at or near the joining surface of the first and second detention members 7 and 8 with the largest dimension, the size between the coupling end portions 8l and 8m can be increased. Further, as the coupling end portions 8l and 8m are located closer to the second holding member 8 side than the joining surface, the spacing between the coupling end portions 8l and 8m becomes smaller according to the outer shape of the cylindrical shape, so that the center portion of the cage 3 is formed. The narrow part formed by the coupling longitudinal grooves 8j and 8k is easy to stand out, and is not preferable in appearance. In addition, since the pin recess 7a and the space inside thereof are also small, problems are likely to occur in the wiring work of the outer leads 5e, 5d, 6e, and 6d and the pin mounting structure. Therefore, it is preferable that the locking end portions 8l and 8m are located at approximately the center of the height dimension of the detention 3.

Further, the first detention member 7 and the second detention member 8 each have six engaging portions thereof, that is, four locking pieces 7p,..., And the second of the first detention member 7. Four positions of the four locking passages 8m, ... of the detention member 8, a pair of bottom engaging recesses 7m, 7m of the first detention member 7, and the second detention member 8 By combining two positions of the pair of engaging projections 8i and 8i, the reliability of the coupling between the first and second detention members 7 and 8 can be improved.

Further, the second detention member 8 located below the gravity direction in the detention 3 in a state where the pair of V springs 11d and 11e of the socket 11 provided on the ceiling surface side are installed in the socket 11. The elastic ring between the multiple ring valves hanging on the second detention member 8

The load of (2) and the stress at the time of removing the lamp are reliably transmitted to the V springs 11d and 11e.

For this reason, it is possible to prevent or reduce the situation in which the second detention member 8 after being installed in the detention section 3 is separated or dropped from the first detention member 7.

According to the annular fluorescent lamp 1, a pair of coupling ends 8l and 8m to which a pair of V springs 11d and 11e of the socket 11 are coupled and a pair of coupling ends 8l and 8m are provided. The pair of vertical grooves 8j and 8k of the guide portion for guiding the V springs 11d and 11e of the second portion together

The locking projections 8c and 8d of the ash 8 are integrally provided, and their positional relationship is fixed. For example, the locking projection piece 7P and the second locking member 8 of the first locking member 7 are fixed. Even when the fitting positions of the coupling through holes 8n are shifted, the positional relationship between these coupling end portions 8l and 8m and the pair of locking projections 8c and 8d of the guide portion is not shifted. For this reason, the pair of V springs 11d and 11e of the socket 11 can be reliably guided and engaged to the engaging ends 8l and 8m by the locking protrusions 8c and 8d.

In addition, the locking projections 8c and 8d are formed when the locking projection piece 7P of the first locking member 7 and the coupling through hole 8n of the second locking member 8 are fitted. 7) Since it protrudes to the side, the thickness (depth dimension of the protrusion direction of the latching projections 8c and 8d) of the engaging end parts 8l and 8m can be enlarged by that much, and the strength of the engaging end parts 8l and 8m is improved. You can. For this reason, even when the pair of V springs 11d and 11e of the socket 11 are repeatedly guided to the engaging ends 8l and 8m by the pair of engaging projections 8c and 8d of the guide portion, the damages thereof are broken. Can be prevented or reduced.

Since the thickness of the coupling end portions 8l and 8m can be increased, the coupling end portions 8l and 8m engaged with the V-shaped locking end portions 11da and 11ea of the pair of V springs 11d and 11e are combined. The angles of the surfaces k and k are not limited to the strength of the coupling ends 8l and 8m, and can be formed at angles that are easy to attach and detach. For example, in the case where the locking projections 8c and 8d are not formed, in order to secure the thickness of the coupling end portions 8l and 8m, it is better than the boundary line between the first and second detention members 7 and 8. The coupling end portions 8l and 8m are moved to the second detention member 8 side, or the center direction of the detention of the engaging surfaces k and k of the coupling end portions 8l and 8m is directed to the bottom surface of the second detention member 8. It is necessary to increase the thickness in the depth direction by inclining to shift. However, the former has a defect such that the narrow portion is conspicuous as described above, and the latter has a small thickness of the outer end portions of the engaging surfaces k and k. According to the inclination angles of k and k, the holding force by the V-shaped locking end portions 11da and 11ea is lowered and the detention 3 suddenly comes out of the socket 11, which is not preferable. On the other hand, according to this embodiment, since the engaging protrusions 8c and 8d can sufficiently secure the thicknesses of the coupling end portions 8l and 8m, the inclination angles formed by the engaging surfaces k and k are determined by the V springs of the sockets. The coupling with (11d, 11e) can be set relatively freely.
