As shown in Fig. 5 and Fig. 6, the first base body 5 is formed with an angular recess 5a at a substantially central portion thereof, and a hollow cylindrical four-headed lamp holder is inserted into the bottom portion 5b of the recess 5a. Pins 5c, 5c, 丄••• are arranged roughly in a square lattice shape to stand vertically. Each lamp cap is inserted inside and outside the 5c _ both ends are open. As shown in Fig. 4, these cap plugs 5c The rib 5d is protruded from the center of the square of the square of the 5c, and the rib 5d& the insertion hole 5e is inserted into the mounting screw (not shown). The inner surface of the first base body 5 is shown, and each of the lamp holder plugs 5c is opened on the bottom surface of the lamp insertion hole 5ca. In the wire insertion holes 5ca, the left and right groups are shown in FIG. One of the 12 I288425pif.doc outer leads 7 and 8 of the wire is inserted, and the sockets 5c, 5c, ..., riveting or welding of the lamp caps are mechanically and electrically connected to the respective lamp caps. Bolts 5c, 5c, .... As shown in Figure 1, one of the groups is connected to the external conductors 7, 8 series, in the figure, with up and down %, 7b, 8a, 8b. The wires are supported by the outer wires 7, 8 to support one of the two ends of the pair of electrodes 9, 10 in the axial direction of the pair of electrodes 9 and 10, respectively. Inner lead) 9a, %, l〇a, 1〇b and sealed in a glass stem 1b12 sealing line 9c, 9d, l〇c, i〇d, all sealed to pass through the lamp The tube end portions 2a and 2b extend outward. At least one of the pair of right and left sleeves 11 and 12 in Fig. 1 is provided with an exhaust pipe 13 formed by communicating with a thin glass tube in the bulb 2. Inside the official 2, the mercury and rare gases in the discharge medium are sealed. However, for this system (4), it is also possible to make the rare gas only enclose the rare gas in the tube 2. However, as shown in Figure 1, the first The base body 5 is a pair of left and right side edges on the inner surface of the bottom portion 5b of the recess 5a. In FIGS. 1A and 1B, the upper and lower pair of columnar-shaped wire defining ribs 14a, 14b, 15a, and 15b are the wire defining members. One of the wire defining ribs i4a, 14b, 15a, 15c shown in Fig. 1A or Fig. 4 is arranged in the specific head plug 5c. The direction in which the radial direction of the square lattice is aligned is higher than that of the outer side. That is, the wire defining ribs l4a, 14b, l5a, i5c are arranged in the radial direction of the base body 5, 6 with a pair of outer side guiding wires 7, 8. Instead of leaving the guide, it is disposed on the inner surface of the first base body 5. Further, in FIGS. 1A, B, and 4, the symbols 16a, 16_the first base body 5 13 128843⁄4^ are a pair of upper and lower joint protrusions, 17 are The inner portion of the first base body 5 is slightly erected inwardly, and is in contact with the central portion of the outer end of the tip end of the bulb end portion 2b, and the angular position of the mounting position is determined when the base 3 is mounted on the bulb 2 The position determines the rib used. As shown in the inner plan view of Fig. 8, a cylindrical columnar rib 18 is formed in a substantially central portion of the inner bottom surface of the second base body 6 so as to protrude from a screw hole 18a (not shown). The upper and lower portions of the columnar ribs are protruded from the upper and lower portions of the columnar ribs to form a pair of cylindrical ribs 19, 19 above and below the coupling holes 19a, 19b. In the ribs 19 and 19, in the coupling holes 19a and 19b, the pair of upper and lower coupling projections 16a and 16b of the first base body M5 are determined by the respective positions, and the state is not shown. The screw is screwed into the screw hole 18a via the insertion hole 5e to form a cylindrical base 3. Further, the second base body 6 is formed on the right and left sides of the columnar rib 18 in Fig. 8, and as shown in the right side view of Fig. 9, the upper and lower pair of predetermined ribs 2a, 2B, 21a, 21b are One piece is set up. As shown in Fig. 2, the displacement defining ribs 20a, 20b, 21a, 21b are free from the front end faces of the second base body 6 to contact the respective wire defining ribs 14a, 14b, 15a, 15b. The free front end positions are each arranged. Further, the free end of the open end side of the second base body 6 and the free leading end faces of the lead defining ribs 14a, 14b, 15a, 15b are not necessarily in contact with each other or the free front end faces may have a gap therebetween. However, this gap requires a smaller gap than the diameter of the outer wires 7a, 7b, 8a, 8b. Thereby, it can be specified that the outer lead wires 7a, 7b, 8a, 8b are displaced beyond the wire regulating ribs 14a, 14 Ι 2884 τ2) 14b, 15a, 15b to the second base body 6, a pair of outer side wires 7, 8 Move to each other in the approach direction. One of the main dimensions of the base 3 thus constituted is as follows. [First base body 5 (refer to Fig. 4)] Full length: 50.0 ± 0.5 mm Outer diameter: 19.6 ± 0.5 mm Length of bottom 5b of recess 5a: 20.0 ± 0.3 mm One of the diametrical directions of the first base body 5 The length of one side of the straight section of the ribs 14a, 14b, 15a, 15b of each of the wire defining ribs 14a, 14b, 15a, 15b is defined by the length of the ribs 14 & 14b, 15a, 15b, and 9.0 ± 〇. 3mm: 2.0 ± 0.5 mm (However, when the wire rib is in the shape of a cylinder, it is converted to the outer diameter 吋). From the center of each of the cap plugs 5c to the length of each of the wire defining ribs Ma, 141), 15a, 15b: 6·〇士〇. 3mm [Second base body 6 (refer to Fig. 8)] Full length: 50·〇士〇·5ππη • Outer diameter: 19.6±0.5mm In the diameter direction of the first base body 5, the pair of displacements define the rib 20a and 20b, 21a and 21b are spaced apart from each other: 9 〇 〇. 3inm The thickness of each rib 20a, 20b, 2la, 21b (the dimension of the second base body 6 in the longitudinal direction) The role of the fluorescent lamp. First, when the base 3 is attached to the outer ends 2a and 2b of the lamp 2, as shown in Fig. 1A, the outer ends of the outer wires are a few, 8&, ribs 15 f.doc I288425pi free leading end portions The outer side of the ribs 14a, 14b, 15a, and 15b in the radial direction is defined by the respective lead wires, and is inserted into the insertion hole 5ca of each of the cap plugs. However, the first base body 5 of the base 3 is placed over the end of the tube 2a, 2b so that the end of the tube is closed, for example, the outer end of the tip of 2b is brought into contact with the position determining rib 17 for position determination. Next, in the inserted state, the outer side wires 7a=b, 8a, and 8b are secured in a plurality of curved states as shown in FIG. 1A, and the lengths of the outer side wires 7a, 7b, 8a, and 8b in the inside 3 are inserted by the respective caps 5c. The caulking of the outer end portion in the radial direction is fixedly attached to each of the caps 5c. - on the open end of the first base body 5, covering the open end of the second lamp, so that the respective engaging protrusions 16a, gi of the first base body 5 are in the respective coupling holes 19a, 19b of the first base body 6. Determine the location. After that, the mounting screw (not shown) is inserted into the squeezing and inserting through hole 5d of the first base body 5, and the screw is inserted into the screw hole of the columnar rib 18 of the second base body 6 by screwing the person. In the 18a, the first base body $ and the second base 6 are strongly coupled. After the lamp cap 3 is installed in the lamp tube 2, as shown in Fig. ib (the surface of the lamp is 2nd and 22nd, 2a, 2b are relatively rotated in the axial direction thereof.) ^, the two ends of the lamp lamp 2a, 2b The axis around the axis is rotated in a Z 2 ϊ μ 2 , for example, the middle portion of the upper side of the upper bow line is in contact; the wire of the back I rib 14 a , 15 a is stretched in the axial direction. Therefore, when the upper side outer lead wire and 8a reach the stretching limit and 16 I28842§pif.d()e ^ pull, the tension in the reverse rotation direction becomes larger, and the rotation angle of the head 3 which is rotated at the predetermined rotation angle reaches the limit. , to limit the rotation above this. However, in the opposite direction, when the lamp cap 3 is rotated, in FIG. 1B, the lower outer side wires 7b, 8b are in contact with the lower side wire defining force 14b 15b' in the middle of the drawing, so as to make the lamp cap 3 Turn the angle port to limit it to less than 360. For example, 90. ~27 (Γ, to 9〇.~12〇. The range is suitable. Again, according to the ring-shaped fluorescent lamp, unlike the conventional example, the lamp ends 2a, 2b do not need to form a ring. The relationship between the concave portions (total portions) can improve the ease and speed of processing of the lamp 2. Moreover, the present invention does not impede the use of the concave portions, and may be at least one end of the annular tube 2 as needed. The annular recess is formed. Further, the simple configuration of the base 3 to form the wire defining ribs 14a, 14b, 15a, and 15b can be simply and surely set to the rotational angle of the base 3. 7a, 7b, the length of the section, 'the rotation angle of the lamp head 3 can be adjusted simply and quickly, and the relationship between the position 17 of the lamp 3 can be easily determined and quickly formed. The position at which the base 3 is mounted on the bulb 2 is determined. The ribs are further: the outer leads 7a, 7b, 8a, and 8b are defined by wires: the relationship between the outer sides of the radial directions of the second and fifth sides, 5a and 15b. Each outer side 17 I288425P, d〇c, but also by the outer wire In addition, in the above-described embodiment, the case where the ribs 14a, 14b, 15a, and 15b are defined by the pair of right and left conductors is described. The invention is not limited thereto. For example, one of the left and right sets of wire defining ribs 14a, 14b, 15a, 15b may be omitted. Further, in the above embodiment, the outer wires 7a, 7b, 8a, 8b are simply The wiring is described on the outer side of the lead defining ribs i4a, 14b, 15a, 15b. It is also possible to wind the outer lead wires 7a, 7b, 8a and ribs in the middle of the wire defining ribs 14a, 14b, 15a, 15b.

The reflector' is connected to the lighting circuit by a pen The lamp holder of the 3rd and the ring-shaped glory lamp 1 are detachably mounted on the lamp holder of the device body 32. The reflection system is formed, for example, in a shape of a white quadrangular pyramid, and is disposed concentrically in the ring-shaped fluorescent lamp i. The lighting circuit 33 is configured to receive electric power from a commercial power source and convert it to a local frequency power of a desired rate. This is supplied to the circular lamp by the lamp holder. According to the knowledge, this A? At the time, the 18 I288424, doc white reflector of the quadrilateral shape of the instrument body 32 is disposed in a substantially concentric relationship in the center of the quadrilateral ring-shaped fluorescent lamp i, and the light distribution characteristic toward the lower side of the instrument becomes a quadrangle. The lighting space in a square-shaped room or the like can be roughly uniformly illuminated. Further, the base 3 of the ring-shaped fluorescent lamp 1 can be 〇 around its central axis. To 12 baht. The relationship of the range of rotation can improve the ease of fitting or even the connection to the socket provided on the body 32 of the appliance.
