- the narrow width portion formed by the engaging vertical grooves 8j and 8k is easily noticeable in the center portion, which is not preferable in appearance.
- the pin recess 7a and the space inside thereof are also reduced, problems are likely to occur in the wiring work of the outer leads 5e, 5d, 6e, 6d and the pin mounting structure. Therefore, it is preferable that the locking step portions 81 and 8m be positioned at the substantially central portion of the height dimension of the base 3.
- first base member 7 and the second base member 8 are provided with the engaging portions at these six locations, that is, the four locking protrusions 7p of the first base member 7, ... And four engagement through-holes 8m of the second base member 8 and a pair of bottom engaging recesses 7m, 7m of the first base member 7 and the second base member 8 Since the two engaging projections 8i and 8i are engaged with each other by two engagements, the reliability of the engagement between the first base member 7 and the second base member 8 is improved. be able to.
- the second base member 8 located on the lower side in the gravitational direction of the base 3 in a state where the pair of V springs l id, l ie of the socket 11 attached to the ceiling surface side is attached to the socket 11 Since it is sandwiched by inertia, the load of the multi-ring valve 2 applied to the second base member 8 and the stress when the lamp is removed are surely transmitted to the V springs l id and l ie.
- the engagement step portions 81, 8m with which the pair of V springs id, lie of the socket 11 are engaged, and the engagement step portions 81, 8m are paired with each other.
- the pair of engaging longitudinal grooves 8j and 8k which are guide portions for guiding the V springs l id and l ie are integrally provided on the locking protrusions 8c and 8d of the second base member 8, respectively. Since these positional relations are fixed, even if the fitting position between the locking projection 7P of the first base member 7 and the engagement through hole 8n of the second base member 8 is shifted, these positions are fixed.
- the positional relationship between the engaging step portions 81 and 8m and the pair of locking projections 8c and 8d which are guide portions does not shift.
- the pair of V springs l id, l ie of the socket 11 The portions 8c and 8d can be reliably guided and engaged with the engaging step portions 81 and 8m.
- the locking protrusions 8c, 8d are formed when the locking protrusion 7P of the first base member 7 and the engaging through hole 8n of the second base member 8 are fitted to each other. Since it protrudes to the base member 7 side, the thickness of the engaging step portions 81 and 8m (the depth dimension in the protruding direction of the locking protrusions 8c and 8d) can be increased accordingly. , 8m strength can be improved. For this reason, even when the pair of V springs l id, l ie of the socket 11 are repeatedly guided to the engagement step portions 81, 8m by the pair of locking projections 8c, 8d, the breakage is prevented or prevented. Can be reduced.
- the engagement step portions 1 Ida and I lea of the pair of V springs l id and l ie are engaged.
- the angles of the engagement surfaces k, k of the engagement step portions 81, 8m are not limited by the strength of the engagement step portions 81, 8m, and can be formed at an angle that allows easy attachment / detachment. For example, when the locking projections 8c, 8d are not formed, the boundary line between the first base member 7 and the second base member 8 in order to ensure the thickness of the engaging step portions 81, 8m.
- the force that moves the engagement step portions 81 and 8m toward the second base member 8 side, the engagement surface k of the engagement step portions 81 and 8m, the center of the base of the k, and the bottom surface of the second base member 8 It is necessary to increase the wall thickness in the depth direction by inclining to deviate.
- the former has a problem such as the conspicuous narrow portion as described above, and the latter has a small thickness at the outer end of the engagement surface k, k, and the engagement strength may be reduced.
- the holding force by the V-shaped locking step portions 1 Ida, I lea is lowered, and the base 3 may be unexpectedly dropped from the socket 11, which is not preferable.
- the engagement protrusions 8c and 8d can sufficiently secure the thickness of the engagement step portions 81 and 8m, so that the inclination angle formed by the engagement surfaces k and k is set to the V of the socket. It can be set relatively freely according to the ease of engagement with the springs l id and l ie.
- FIG. 14 is a plan view of a lighting fixture 21 according to the second embodiment of the present invention.
- the luminaire 21 includes the annular fluorescent lamp 1 shown in FIG. 1 above, an instrument main body 22 on which the annular fluorescent lamp 1 is detachably attached, and the instrument main body 22. And a lighting circuit 23 for supplying electric power.
- the fixture body 22 is attached to the ceiling, for example, a reflector (not shown), a lamp socket that is electrically connected to the lighting circuit 23, and a lamp holder that attaches the annular fluorescent lamp 1 to the fixture body 22 in a detachable manner. It has equipment.
- the reflector is, for example, a white square It is formed in a conical shape and is arranged concentrically inside the annular fluorescent lamp 1.
- the lighting circuit 23 obtains electric power from a commercial power source, converts it into high-frequency electric power having a required frequency, and supplies it to the annular fluorescent lamp via a lamp socket.
- the quadrangular pyramid-shaped white reflector of the fixture body 22 is disposed substantially concentrically at the center of the square annular fluorescent lamp 1, and therefore, it is arranged in the downward direction of the fixture.
- the light characteristics are quadrangular, and the illumination space such as a quadrangular room can be illuminated almost uniformly.
