  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

(Embodiment 1)
FIG. 1 is a schematic side view of a lighting fixture for a straight tube fluorescent lamp according to an embodiment of the present invention. FIG. 2 shows a state where a fluorescent lamp is attached to the lighting apparatus according to the embodiment of the present invention.

  The luminaire 100 includes a luminaire main body 1, a fluorescent lamp 2, a movable socket 3, a socket auxiliary tool 4, and a fixed socket 5. The luminaire main body 1 includes a lighting circuit, a connector, and the like (not shown), and is configured by a housing that accommodates them. The circuit of the luminaire body 1, the movable socket 3 and the fixed socket 5 can be electrically connected to supply power to the lighting circuit to light the fluorescent lamp 2. The luminaire main body 1 is directly fixed to a mounting surface such as a ceiling.

  The luminaire main body 1 includes an arm 11 and an arm 12 at positions where the fluorescent lamp 2 is sandwiched from both ends in the longitudinal direction of the straight fluorescent lamp 2.

  The straight tube type fluorescent lamp 2 includes a luminous tube 21, a base 22, and a lamp pin 23.

  FIG. 3 is a schematic diagram of the socket and the socket auxiliary tool of the lighting fixture according to Embodiment 1 of the present invention. FIG. 3A is a partially enlarged view of a portion surrounded by a one-dot chain line R in FIG. FIG. 3B is a diagram when FIG. 3A is viewed in the direction of the arrow.

  The movable socket 3 includes two insertion holes 31 of the lamp pin 23 of the fluorescent lamp 2 at the center. The movable socket 3 is formed with a deep concave portion 32, and the fluorescent lamp 2 can be fitted and supported. When the fluorescent lamp 2 is fitted and supported, the insertion hole 31 of the movable socket 3 and the lamp pin 23 of the fluorescent lamp 2 come into contact with each other, and electrical connection from the lighting fixture body 1 to the fluorescent lamp 2 becomes possible. The deep concave portion 32 has a depth that covers the base 22 of the fluorescent lamp 2 and is preferably a depth that does not engage the arc tube 21 when fitted. By forming a recess at a predetermined depth in the deep recess 32, the fluorescent lamp 2 fitted to the movable socket 3 is difficult to come off.

  FIG. 4 is a side view showing an example of the socket auxiliary tool. 4A shows a case where a fluorescent lamp is attached to the luminaire main body, FIG. 4B shows a case where the fluorescent lamp is attached only to the movable socket side, and FIG. 4C shows a case where the fluorescent lamp is attached.

  The socket auxiliary tool 4 is located between the movable socket 3 and the arm 11 and can maintain the electrical connection between the lighting fixture body 1 and the fluorescent lamp 2. The socket auxiliary tool 4 formed of an insulating and heat-resistant material has a shape composed of a nesting structure in which one cylinder can be inserted into another cylinder and slidable. Is provided. When the fluorescent lamp 2 is attached to the luminaire main body 1, a biasing force acts on the fluorescent lamp 2 in the direction from the movable socket 3 to the fixed socket 5.

  Specifically, the socket auxiliary tool 4 (see FIG. 4C) with the fluorescent lamp 2 attached to the luminaire main body 1 is the same as the socket auxiliary tool 4 (see FIG. 4A) before the fluorescent lamp 2 is attached. In comparison, it is in a contracted state. A force is applied to the fluorescent lamp 2 from the movable socket 3 toward the fixed socket 5 to restore the contracted amount of the socket auxiliary tool 4, thereby connecting the fluorescent lamp 2 and the movable socket 3 and the fluorescent lamp 2. And the fixed socket 5 are firmly connected, and the electrical connection between the lighting fixture body 1 and the fluorescent lamp 2 is easily maintained.

  As shown in FIG. 4B, when attaching the fluorescent lamp 2 to the movable socket 3 side, the socket auxiliary tool 4 can be bent with the attachment position to the arm 11 as a fulcrum. The lamp pin 23 of the fluorescent lamp 2 is hooked on the end of the movable socket 3 so that the surface facing the base 22 of the movable socket 3 (that is, the bottom surface of the deep recess 32) is fluorescent from the direction facing the fixed socket 5. The direction can be changed to the side facing the mounting surface of the luminaire main body 1 with the lamp 2 interposed therebetween. With the socket auxiliary tool 4, the facing direction of the movable socket 3 changes, and the fluorescent lamp 2 can be attached in a state where one side of the fluorescent lamp 2 is held at a low position.

  FIG. 5 is a view showing a modification of the socket auxiliary tool, and the basic structure is the same as FIG. The socket auxiliary tool 4 may have a shape constituted by the bellows structure shown in FIG.

  FIG. 6 is a schematic view of the socket of the lighting fixture according to Embodiment 1 of the present invention. The case where the guide groove formed in the socket is L-shaped is shown. FIG. 6A is a partial enlarged view of the portion R surrounded by an alternate long and short dash line in FIG. FIG. 6B is a diagram when FIG. 6A is viewed in the direction of the arrow.

  Similar to the movable socket 3, the fixed socket 5 includes two insertion holes 51 of the lamp pin 23 of the fluorescent lamp 2 in the center. In the fixed socket 5, a guide groove 53 serving as a passage for the lamp pin 23 is formed so that the lamp pin 23 can be easily fitted toward the insertion hole 51. The opening 53a of the guide groove 53 is formed on the side facing the mounting surface of the luminaire main body 1 with the fluorescent lamp 2 interposed therebetween. The end portion 53b of the guide groove 53 is connected to the insertion hole 51. By passing the lamp pin 23 through the opening 53a into the guide groove 53, the lamp pin 23 can be easily inserted into the insertion hole 51. The electrical connection between the main body 1 and the fluorescent lamp 2 can be maintained. When the lamp pin 23 is inserted into the insertion hole 51, the fluorescent lamp 2 is urged in a direction to remove the fluorescent lamp 2 from the movable socket 3, and the fluorescent lamp 2 and the fixed socket 5 are fitted in close contact with each other. At this time, the shallow concave portion 52 can firmly fix the position of the fluorescent lamp 2 and can cover the tip of the base 22 of the fluorescent lamp 2 to prevent dust and the like from adhering to the lamp pin 23. Even if the shallow recess 52 is not formed, there is no problem in the configuration of the lighting apparatus 100.

  The width of the guide groove 53 is preferably formed in a shape that widens toward the opening 53a and widens at the bottom. The large width of the guide groove 53 on the side through which the lamp pin 23 is passed makes it easier to pass the lamp pin 23 through the guide groove 53, and the small width of the guide groove 53 on the side into which the lamp pin 23 is inserted makes it difficult for the lamp pin 23 to fall off. Because it becomes. For example, the width of the guide groove 53 on the side through which the lamp pin 23 is passed is twice the diameter of the lamp pin 23 and the width of the guide groove 53 on the side into which the lamp pin 23 is inserted is sufficiently wide when passing through the lamp pin 23. The width is approximately the same as the diameter of 23. Further, the opening 53a side may be wider than the end portion 53b side. Furthermore, since the width of the guide groove 53 is formed in a shape that smoothly narrows from the opening 53a side to the end portion 53b, it is easy to move the lamp pin 23 along the guide groove 53. The lamp pin 23 can be inserted into the insertion hole 51.

  The guide groove 53 is preferably formed in any one of L shape, U shape, and U shape. This is because the end portion 53 b is not on an extension line from the opening 53 a via the guide groove 53, so that the lamp pin 23 is difficult to be removed from the insertion hole 51.

  FIG. 6B shows a case where the guide groove 53 is L-shaped and the width is widened. FIG. 7A shows a case where the shape of the guide groove 53 is a U-shape and the width is wide on the opening side. FIG. 7B shows a case where the shape of the guide groove 53 is U-shaped, the width is widened at the bottom, and the opening side is wide.

  As described above, according to the lighting apparatus according to Embodiment 1, the fluorescent lamp is fitted to the movable socket without climbing on the stepladder, etc., by making the socket auxiliary device movable with one socket. The working time for fitting the fluorescent lamp to the other socket can be shortened, and the fluorescent lamp can be exchanged, in particular, attached safely. When the fluorescent lamp is fitted into the socket on a stepladder or the like, since one end of the fluorescent lamp is supported, the mounting operation can be performed with one hand. In addition, by forming a groove for guiding the lamp pin in the socket, the socket and the fluorescent lamp can be easily and reliably electrically connected, so that the working efficiency can be improved and the working time can be shortened. Therefore, it is possible to reduce the risk of dropping the person and the fluorescent lamp and to increase the safety, and to easily and reliably replace the fluorescent lamp in a short time.

FIG. 9 is a schematic view of a socket of a lighting fixture according to Embodiment 2 of the present invention. FIG. 9A is a side view of a portion corresponding to the one-dot chain line encircled portion R in FIG. FIG. 9B is a diagram when FIG. 9A is viewed in the direction of the arrow. The basic structure of the lighting fixture according to the second embodiment is the same as that of the lighting fixture 100 according to the first embodiment, and includes a lighting fixture main body 1, a fluorescent lamp 2, a movable socket 6, a socket auxiliary tool 7, and a fixed socket 8. . In the second embodiment, instead of the arm 11 of the luminaire 1, a mounting arm 72 is provided on the socket auxiliary tool 7. Further, the socket auxiliary tool 7 does not have elasticity, and the cylinder 71 rotates around the shaft 73 and moves. Further, the movable socket 6 and the fixed socket 8 rotate the fluorescent lamp 2 by 90 degrees around the center in the longitudinal direction to bring the lamp pin 23 of the fluorescent lamp 2 into contact with the sandwiching type terminal 62 and the sandwiching type terminal 82. The fixing socket 8 and the fluorescent lamp 2 are mechanically fixed and electrically connected.

  The movable socket 6 includes an attachment portion 61 and a pinch type terminal 62. The mounting portion 61 formed to be concave in the movable socket 6 also serves as a guide for the lamp pin 23. When the fluorescent lamp 2 is mounted by being rotated 90 degrees around the center in the longitudinal direction, the pin-type terminal 62 and the lamp pin 23 come into contact with each other, and the movable socket 6 and the fluorescent lamp 2 are mechanically fixed and electrically connected.

  The socket auxiliary tool 7 includes a cylinder 71, an attachment arm 72, and a shaft 73. The attachment arm 72 is attached to the luminaire main body 1 with, for example, a U-shaped bracket. The cylinder 71 is supported by the shaft 73 so as to be sandwiched between the attachment arms 72. The movable socket 6 is provided inside the cylinder 71, and the movable socket 6 can be rotatably supported by the cylinder 71 rotating about the shaft 73. The tube 71 is connected to the luminaire main body 1 by a lead (not shown), and the movable socket 6 and the luminaire main body 1 can maintain an electrical connection via the socket auxiliary tool 7.

  The fixed socket 8 includes a mounting portion 81, a pin-type terminal 82, a guide 83, and a slit 84. The guide 83 is formed between the attachment portion 81 and the sandwiched terminal 82. The fluorescent lamp 2 is aligned so that the lamp pin 23 is parallel to the direction of the slit 84 and the lamp pin 23 is inserted from the slit 84 to the guide 83 and inserted to a predetermined position. Rotate around 90 degrees and wear. At this time, the pin-type terminal 82 and the lamp pin 23 are in contact with each other, and the fixing socket 8 and the fluorescent lamp 2 are mechanically fixed and electrically connected.

  Actually, the fluorescent lamp 2 is fitted into the movable socket 6 and inserted into the slit 84 of the fixed socket 8 through the lamp pin 23 of the fluorescent lamp 2 to a predetermined position, and the fluorescent lamp 2 is moved around the longitudinal center 90. Rotate and install.

  When attaching the fluorescent lamp 2, first, the lamp pin 23 of the fluorescent lamp 2 is hooked on the end of the movable socket 6, and the surface facing the base 22 of the movable socket 6 (namely, the attachment portion 61) is fixed to the fixed socket 8. The direction can be changed from the direction facing to the side facing the mounting surface of the luminaire main body 1 across the fluorescent lamp 2. Since the tube 71 of the socket auxiliary tool 7 is rotatable about the shaft 73, the facing direction of the movable socket 6 changes, and the fluorescent lamp 2 is held in a state where one side of the fluorescent lamp 2 is held at a low position. It can be attached. The fluorescent lamp 2 can be fitted and supported on the mounting portion 61 formed in a concave shape. At this time, the fluorescent lamp 2 is inserted so that the lamp pins 23 of the fluorescent lamp 2 are aligned vertically with respect to the mounting surface of the luminaire main body 1. When the movable socket 6 and the fluorescent lamp 2 are fitted, the fluorescent lamp 2 is rotated around the socket auxiliary tool 7 so that the fluorescent lamp 2 is parallel to the mounting surface of the luminaire main body 1. When the lamp pin 23 passes through the slit 84 of the fixed socket and is inserted to a predetermined position, the fluorescent lamp 2 is rotated by 90 degrees around the longitudinal center. The pin terminals 62 and 82 and the lamp pin 23 of the fluorescent lamp 2 are in contact with each other, and the fixing socket 8 and the fluorescent lamp 2 are mechanically fixed and electrically connected.

  As described above, according to the lighting apparatus according to the second embodiment, the fluorescent lamp is fitted to the socket on one side without climbing the stepladder, etc., by making the socket auxiliary device movable with one socket. The working time for fitting the fluorescent lamp to the other socket can be shortened, and the fluorescent lamp can be exchanged, in particular, attached safely. When the fluorescent lamp is fitted into the socket on a stepladder or the like, since one end of the fluorescent lamp is supported, the mounting operation can be performed with one hand. Therefore, it is possible to reduce the risk of dropping the person and the fluorescent lamp and to increase the safety, and to easily and reliably replace the fluorescent lamp in a short time.

  In the first embodiment, the movable socket 3 and the fixed socket 5 and the fluorescent lamp 2 are connected by the method of inserting the lamp pin 23 into the insertion holes 31 and 51. However, the movable socket 6 described in the second embodiment is used. Alternatively, a method may be used in which the fluorescent lamp 2 is rotated to perform mechanical fixing and electrical contact using the fixing socket 8.

  In the second embodiment, the method of connecting the movable socket 6 and the fixed socket 8 to the fluorescent lamp 2 is a system in which the fluorescent lamp 2 is rotated to perform mechanical fixing and electrical contact. The lamp pin 23 may be inserted into the insertion holes 31 and 51 using the movable socket 3 and the fixed socket 5 described in FIG. However, since the socket auxiliary tool 7 does not have elasticity, it is configured with a plunger structure in which the mounting surface of the base 22 moves by applying a load to the movable socket 3 itself from the fixed socket 5 side to the movable socket 3 side. When attaching the fluorescent lamp 2 to the fixed socket 5 side, it is preferable to insert the lamp pin 23 while applying a load. By configuring the movable socket 3 with a plunger structure, the electrical connection between the movable socket 3 and the fluorescent lamp 2 and between the fixed socket 5 and the fluorescent lamp 2 can be strengthened.

  FIG. 10 is a schematic configuration diagram showing a specific example of the embodiment of the present invention. FIG. 10 (a) assumes an office, a ceiling height of 260 cm, and a commercial straight tube fluorescent lamp (standard tube length 1198 mm) is used. FIG. 10 (b) assumes a residence, and the ceiling height is 240 cm. An example in the case of using a general household straight tube fluorescent lamp (standard tube length 580 mm) is shown. The person who attaches the fluorescent lamp is assumed to be a general male, and the average height of a Japanese general male is assumed to be 170 cm. The height reached when the hand is extended is about 210 cm, and the height of the hand when holding the fluorescent lamp is about 200 cm. The ceiling height is 210 cm or more, which is often found in office buildings, and 240 cm, which is often found in office buildings.

  When installing fluorescent lamps, as the place where the fluorescent lamp is gripped is closer to the end, it becomes difficult to support the fluorescent lamp when it is held, so it is easy to drop, and it is difficult to fit the fluorescent lamp into the socket. Arise. In particular, the longer the fluorescent lamp tube length, the greater the effect.

  When the lighting fixture using the socket auxiliary tool according to the present invention is used, the socket auxiliary tool can tilt the mounting surface of the socket downward by 45 degrees. When installing the fluorescent lamp when replacing the fluorescent lamp, if it becomes possible to fit the fluorescent lamp into the socket from the diagonal direction with the mounting surface inclined 45 degrees downward, not from the horizontal direction, One socket can be fitted without using such as.

  For example, in FIG. 10A, the tube length of the fluorescent lamp is 1198 mm, which is difficult to handle, but the end reaches a height that can be reached without reaching. When mounting is assumed, it can be operated with the fluorescent lamp held at about one-third of the edge, there is little risk of the fluorescent lamp falling, and there is little hindrance to the socket mounting operation. . In FIG. 10B, the tube length of the fluorescent lamp is as short as 580 mm, and even if it is held near the end, a problem hardly occurs. In both cases, it is necessary to carry out the work while holding the fluorescent lamp at a position higher than its own height, but it is possible to prevent the fluorescent lamp from falling and to perform the installation work without reducing the work efficiency. it can. Further, since the work can be performed in a stable posture with the foot on the ground, there is no danger of stepping off the scaffold.

  It is necessary to use a stepladder etc. when fitting the other socket, but when working, a stepladder can be prepared under the socket that requires fitting, so that the fitting of the fluorescent lamp into the socket is close to the hand This can be done and work efficiency is improved. In addition, since one of the fluorescent lamps is supported by the socket, it can be held without breaking the balance even if it is held near the end (the other side) instead of near the center of the fluorescent lamp, and one-handed operation is also possible. Therefore, the stepladder can be caught with the free hand, the fluorescent lamp and itself can be prevented from falling, and the work can be performed safely.

  Furthermore, the guide groove provided in the socket allows the lamp pin of the fluorescent lamp to be inserted into the socket in a short time, and the electrical connection can be reliably performed. Not only can the time required for exchanging the fluorescent lamp be shortened, but also the work time on an unstable scaffold can be shortened, so that the risk of a person falling can be reduced.

  As described above, according to the lighting apparatus according to the embodiment, the fluorescent lamp is fitted to the socket on one side without climbing the stepladder or the like by providing the socket auxiliary tool in one socket and making it movable. It is possible to shorten the work time when fitting the fluorescent lamp to the other socket, and to perform replacement of the fluorescent lamp, in particular, installation work safely. When the fluorescent lamp is fitted into the socket on a stepladder or the like, since one end of the fluorescent lamp is supported, the mounting operation can be performed with one hand. In addition, by forming a groove for guiding the lamp pin in the socket, the socket and the fluorescent lamp can be easily and reliably electrically connected, so that the working efficiency can be improved and the working time can be shortened. Therefore, it is possible to reduce the risk of dropping the person and the fluorescent lamp and to increase the safety, and to easily and reliably replace the fluorescent lamp in a short time.
