  The lighting fixture 10 which concerns on embodiment of this invention is demonstrated. In the following description, unless otherwise specified, each member will be described in the direction in which the lighting fixture 10 is assembled.

FIG. 1 is a side view showing an overall configuration of a lighting fixture according to an embodiment of the present invention. FIG. 2 is a perspective view of the lighting fixture.
The luminaire 10 is a luminaire using a lamp 1 that uses an LED (light-emitting diode) as a light source. The light source is not limited to the LED, but may be another light source such as a fluorescent lamp or organic electroluminescence illumination. As shown in FIG. 1, the luminaire 10 is directly attached to or suspended from a mounting surface 8 such as a ceiling. 1 is defined as “longitudinal direction”, the Y-axis direction is defined as “thickness direction”, and the Z-axis direction is defined as “width direction”.

  The lighting fixture 10 mainly includes a fixture main body 2 to which the lamp 1 is attached and a lamp holder 3 that regulates the removal of the lamp 1 from the fixture main body 2. Further, the lamp 1 is a straight tube type, that is, a rod-shaped LED lamp, and terminals for electrical connection with the instrument body 2 are formed at both ends in the longitudinal direction.

  The fixture body 2 is a main structure of the lighting fixture 10. The instrument body 2 mainly has a housing part 21, a connection part 22, and a locked part 23.

  The accommodating part 21 is formed in a box shape by sheet metal processing with a metal plate such as aluminum having thermal conductivity. The accommodating portion 21 is a portion in which a power supply device, a lighting device, and the like for lighting the lamp 1 are accommodated. The accommodating portion 21 has a height (thickness direction dimension) and a width direction dimension for accommodating a power supply device, a lighting device, and the like inside, and the longitudinal dimension is a length that allows the lamp 1 to be mounted. Yes. The upper surface (upper surface in the thickness direction) of the accommodating portion 21 is formed to be attachable to the attachment surface 8. The lower surface (opposite side of the upper surface) of the housing portion 21 is a side on which the lamp 1 is mounted, and serves as a reflecting plate that reflects light emitted upward from the lamp 1 downward.

  The connection part 22 includes a hole into which a terminal provided in the lamp 1 can be inserted, and a connection terminal disposed inside the hole. The connection unit 22 can mechanically hold the lamp 1 by connecting a terminal provided in the lamp 1 to the connection terminal, and also supplies power to the lamp 1 from the power supply device or the lighting device via the terminal and the connection terminal. Can be supplied. The connection part 22 is a general lamp socket. The connection unit 22 is electrically connected to the power supply device and the lighting device in the housing unit 21. One connecting portion 22 is disposed at each of both ends of the accommodating portion 21 in the longitudinal direction. The connecting portion 22 is provided so as to protrude from the inside of the housing portion 21 to the lower side of the housing portion 21 in order to hold both end portions of the lamp 1. That is, the lamp 1 is held by the instrument body 2 by inserting the terminals at both ends of the lamp 1 into the holes of the connecting portions 22 and 22. Moreover, the connection part with the lamp | ramp 1 in the connection part 22 is comprised so that a movement in the longitudinal direction of the lamp | ramp 1 is possible a little.

  The locked portion 23 is for locking the lamp holder 3. The locked portion 23 is provided in the lower portion of the accommodating portion 21 in the thickness direction. Since the locked portion 23 is a hole that penetrates in the thickness direction, it is easy to form. The locked portion 23 is provided in the vicinity of the connecting portions 22 and 22 that are positions where it is difficult to block the light of the lamp 1. Since two lamp holders 3 are provided with respect to the instrument body 2, the locked portions 23 are formed at four locations below the housing portion 21.

  In addition, although the to-be-latched part 23 is only one pair with respect to the one lamp holder 3, you may provide the to-be-latched part 23 further in multiple places. Moreover, the to-be-latched part 23 is not restricted to a through-hole, For example, a bottomed hole may be sufficient, and when the thickness of the accommodating part 21 is thick, it may form in groove shape. Further, the locked portion 23 may be arranged at the center in the longitudinal direction of the instrument body 2 in order to make it difficult to remove the lamp 1. Although the lamp 1 of the present embodiment is a straight tube type and the instrument body 2 is a box shape, other shapes such as an annular lamp and an instrument body may be used. Moreover, although the two lamp holders 3 and 3 are provided in the instrument main body 2, you may provide one place or three places or more depending on the shape of the instrument main body or the lamp.

Next, the lamp holder 3 will be described with reference to FIGS.
3 is a simplified cross-sectional view taken along line II-II in FIG. 4 is a view taken along the line III in FIG. FIG. 5A is a front view of the lamp holder. FIG. 5B is a side view of the lamp holder.

  The lamp holder 3 is for restricting the movement range (movement in the thickness direction and width direction) of the lamp 1 mounted on the instrument body 2 so that it cannot be easily detached from the instrument body 2. As an example, the lamp holder 3 is made of a synthetic resin such as polycarbonate. The lamp holder 3 only needs to be made of at least an elastically deformable material, and may be made of metal or the like as long as it is elastically deformed. In a state in which the lamp holder 3 is mounted on the fixture body 2, it is desirable that at least a portion where the light hits be transparent or translucent so that light emitted from the lamp 1 is difficult to block. In the present embodiment, the entire lamp holder 3 is transparent. The lamp holder 3 mainly has a restriction portion 31 and a check locking portion 32.

  The restricting portion 31 is a portion that faces the outer peripheral surface of the lamp and restricts the moving range of the lamp 1 and is formed in a U shape as shown in FIG. The inner dimension of the restricting portion 31 is formed such that the outer peripheral surface of the lamp 1 is in contact with the outer peripheral surface of the lamp 1 or a space that is slightly spaced from the outer peripheral surface of the lamp 1. A linear rib 33 is formed on the outer surface of the restricting portion 31 so as to protrude outward in order to improve the rigidity of the restricting portion 31. The rib 33 can be omitted if the rigidity of the restricting portion 31 can be secured. Further, in the side view shown in FIG. 5B, the restricting portion 31 has a width W1 on the check locking portion 32 side, that is, a fixed side, larger than a width W2 on the lamp 1 side, that is, the lower side. With such a dimensional relationship, the rigidity of the entire lamp holder 3 is improved, and the area of the portion where the light of the lamp 1 hits or passes through the restricting portion 31 can be reduced. It becomes difficult to block 1 light. As shown in FIG. 5A, the restricting portion 31 is formed with plate-like flange portions 34 and 34 that protrude outward from both ends.

  As shown in FIGS. 3 to 5, the check locking portion 32 locks in a non-return manner to the locked portion 23 that is a hole formed in the instrument body 2, that is, is inserted into the locked portion 23. Once locked, the locked state with the locked portion 23 cannot be easily released once locked. The check locking portion 32 is connected to the restriction portion 31 via the flange portion 34. The check locking portion 32 mainly includes a locking column 35 and check pieces 36 and 36.

  The locking column 35 is a portion formed in a columnar shape, and is provided so as to protrude upward from the upper surface of the flange portion 34. The outer dimension of the locking column 35 is set to be smaller than the diameter (opening width dimension) of the hole that is the locked portion 23. The check pieces 36 and 36 are portions extending obliquely downward from the upper end portion of the locking column 35, and are provided as a pair with the one locking column 35 interposed therebetween. The gap between the check piece 36 and the locking column 35 is set so as to increase toward the lower side. Further, the clearance between the free end of the check piece 36 and the flange 34 is set to be slightly larger than the thickness around the locked portion 23 of the accommodating portion 21. The check locking portion 32 is formed in a substantially arrow shape as a whole, and is formed in a tapered shape whose outer surface extends from the upper end to the lower end. The external dimension in plan view of the lower end portion of the check piece 36 is set to be slightly larger than the diameter (opening width dimension) of the hole serving as the locked portion 23. That is, the lower end portion of the check piece 36 is set so as to contact the periphery of the hole that is the locked portion 23.

  Next, a method for attaching the lamp 1 and the lamp holder 3 to the instrument body 2 will be described.

  6A is a diagram illustrating a state of the lighting fixture before the lamp holder is mounted, and FIG. 6B is a diagram illustrating a state of the lighting fixture after the lamp holder is mounted. FIG. 7A is a diagram illustrating a state of the check locking portion being inserted into the locked portion. FIG. 7B is a diagram illustrating a state of the check locking portion after being inserted into the locked portion. FIG. 8A is a diagram illustrating a state of the check locking part being inserted into the locked part. FIG. 8B is a diagram illustrating a state of the check locking portion after being inserted into the locked portion.

  First, as shown in FIG. 6A, the lamp 1 is mounted on the instrument body 2 by inserting both end portions of the lamp 1 into connection portions 22 and 22, respectively. Next, the lamp holder 3 is displaced in the direction indicated by the arrow A, and the check locking portion 32 of the lamp holder 3 is inserted into the locked portions 23 and 23 which are holes (see FIG. 2). That is, as shown in FIG. 7A, the distal end portion of the check locking portion 32 of the lamp holder 3 is inserted into the locked portion 23 from below the housing portion 21. At this time, since the tip end portion of the check locking portion 32 is smaller than the diameter of the locked portion 23, it can be easily inserted into the accommodating portion 21 via the locked portion 23. Further, when the locked portion 23 is inserted into the housing portion 21, the check pieces 36 and 36 are pushed by the inner peripheral surface of the locked portion 23 and elastically deformed toward the locking column 35, Once, the outer dimension of the check locking portion 32 is reduced. Next, when the contact between the outer surface of the check pieces 36 and 36 and the locked portion 23 is eliminated, as shown in FIG. 7B, the check pieces 36 and 36 are connected to the locked portion 23. Return to the original shape larger than the diameter. That is, the check locking part 32 can be easily inserted into the locked part 23 simply by pushing the lamp holder 3 upward.

  Then, since the lower end portions of the check pieces 36 and 36 are opposed to the inner surface of the housing portion 21, the check lock portion 32 cannot be detached from the locked portion 23. This state is defined as a “locking state”. Further, the check locking portion 32 is not exposed to the outside from the housing portion 21 in a state where the check locking portion 32 is locked to the locked portion 23. Therefore, the locked state between the locked portion 23 and the check pieces 36 and 36 cannot be easily released. In addition, the lower end portions of the check pieces 36 and 36 and the upper surface of the flange portion 34 sandwich the accommodating portion 21 around the locked portion 23. Therefore, even if the restricting portion 31 is moved greatly, the locked state between the locked portion 23 and the check locking portion 32 is not easily released. And in the state which the to-be-latched part 23 latched the non-return latching part 32, the lamp holder 3 cannot be removed from the instrument main body 2 easily. Since the restricting portion 31 restricts the movement range of the lamp 1, the lamp 1 attached to the instrument body 2 cannot be easily removed. Therefore, careless removal of the lamp 1 attached to the instrument body 2 can be prevented, and an inappropriate lamp can be prevented from being attached to the instrument body 2.

  Thus, by integrally configuring the restricting portion 31 and the check locking portion 32, the number of parts can be reduced, and the lamp holder 3 can be easily moved to the locked portion 23 without using a fixture such as a driver. And can be locked.

  On the other hand, when the lamp 1 is replaced, the lamp 1 is removed from the instrument body 2 by cutting the restricting portion 31 of the lamp holder 3 with a cutting tool such as a nipper to widen the moving range of the lamp 1. Alternatively, by disassembling the instrument main body 2 and pressing the check pieces 36 and 36 toward the locking column 35, the outer dimension of the lower portion of the check locking portion 32 is reduced, and the lower portion of the locked portion 23 is By moving the check locking part 32 to the side, the locked state of the locked part 23 and the check locking part 32 is canceled, and the lamp 1 is removed from the instrument body 2. These two methods are conceivable, but both require extremely difficult work. Therefore, it is possible to prevent an inappropriate lamp from being attached to the instrument body 2.

  As shown in FIG. 3, the distance between the pair of locked portions 23 and 23 of the present embodiment is substantially the same as the distance between the pair of locking columns 35 and 35 of the check locking portions 32 and 32. It is preferable to set so that. Since the restricting portion 31 of the lamp holder 3 is elastically deformed, it is an instrument main body in which the distance between the pair of locking columns 35 is shorter or longer than the distance between the locked portions 23. However, the position of the check locking portion 32 can be inserted in accordance with the locked portions 23 and 23. That is, since high position accuracy is not calculated | required with respect to the to-be-latched parts 23 * 23, the manufacturing cost of the accommodating part 21 and the instrument main body 2 containing it can be reduced.

  As another embodiment, a lamp holder 3a shown in FIG. 8 is also conceivable.

  Specifically, as shown in FIG. 8, one to-be-latched portion 23 a that is a hole formed in the instrument main body 2 is formed instead of two for one lamp holder 3 a. In the lamp holder 3a, the restricting portion 31a is formed in a substantially annular shape, and check locking portions 32a and 32a are formed at both ends of the restricting portion 31a. The check locking portion 32a includes a locking post 35a and a check piece 36a. The locking column 35a is a columnar portion provided so as to protrude upward from the end of the restricting portion 31a. A check piece 36a is provided so as to protrude obliquely downward from the upper end of the restricting portion 31a.

  In the lamp holder 3a, the locking pillars 35a and 35a are opposed to each other, and the check locking portions 32a and 32a are inserted into one locked portion 23a. After the insertion, the opposing sides of the locking pillars 35a and 35a are separated, and the end portions of the check pieces 36a and 36a are brought into contact with the accommodating portion 21 around the locked portion 23a so that the locked state is maintained.
