Patent Document 1 discloses an LED lighting module (lighting fixture) that is arranged along the underside of a raceway.

JP 2015-173090 A

When installing an LED lighting module (lighting fixture) close to the bottom of a raceway, in order to facilitate installation, it is advisable to provide the LED lighting module (lighting fixture) with a terminal block for power supply, and furthermore to place the terminal block on the external top surface of the LED lighting module (lighting fixture). Normally, the terminal block is housed inside the raceway, but when using a hanging bracket to suspend the raceway from the ceiling, depending on the location where the LED lighting module (lighting fixture) is attached, the hanging bracket and the terminal block may interfere with each other, making it impossible to attach the LED lighting module (lighting fixture) to the desired location.

The present invention was made in consideration of these problems, and aims to provide a lighting fixture that can be attached to a raceway or the like in a desired location, regardless of the position of the hanging bracket.

To solve the above problems, the lighting fixture of the present invention includes a terminal block and a housing portion capable of housing at least a portion of the terminal block, the terminal block is supported by an elastic member so that at least a portion of the terminal block protrudes from the housing portion, and when the terminal block is pressed, the elastic member deforms, increasing the portion housed in the housing portion.

The above-mentioned configuration has the effect of making it easy to connect the power line to the terminal block when mounting the lighting fixture on a raceway, etc., while allowing the lighting fixture to be mounted in the desired location close to the raceway, etc., without being affected by obstacles such as hanging hardware.

The following describes an embodiment of the present invention with reference to the drawings. Note that unless otherwise specified, directions are indicated according to up, down, left and right in each drawing, with FIG. 1(a) being the front of the lighting fixture.

1. First embodiment
Hereinafter, a lighting fixture 1 according to a first embodiment of the present invention will be described with reference to the drawings.
The lighting fixture 1 has a rectangular parallelepiped shape that is attached to a rail-like member that is an example of a structure such as a raceway 7, and is usually attached to the ceiling side to illuminate the floor surface, and as shown in Figures 1(a) and (b), it includes a mounting member 11, a cover member 12, cap members 13L and 13R, mounting springs 14L and 14R, storage springs 15L and 15R that are an example of an elastic member, terminal blocks 162L and 162R, earth wires 164L and 164R, earth connectors 163L and 163R, and a power supply unit 161. Furthermore, as shown in Figure 5, the lighting fixture 1 includes a printed circuit board 18 and an LED 19.

The raceway 7 is generally suspended from the ceiling by anchor bolts or the like, and is a rail-shaped metal structural member for accommodating power wiring and installing electrical equipment such as lighting fixtures. As shown in Figures 3(a) and (b), it has an opening 71 and opening outer edges 72a and 72b. Also, as shown in Figures 4(a) and (b), the components used when suspending the raceway 7 from the ceiling or the like include a hanging bracket 77, nuts 78U and 78D, and a hanging bolt 79.

As shown in Figures 1(a), 1(b), 2(a), 4(a), 4(b) and 5, the mounting member 11 is a generally trough-shaped metal member with a heat sink function, and is part of the exterior of the lighting fixture. The mounting member 11 has a bottom surface 111 and side wall protrusions 112L and 112R, and is extruded so that the power supply 161 can be slidably inserted on the upper side of the bottom surface 111, and the printed circuit board 18 with LEDs 19 mounted on the lower side can be slidably inserted.

The mounting springs 14L and 14R are metal members with spring properties that are fitted into the opening 71 at the bottom of the raceway to secure the lighting fixture, and as shown in Figure 1 (b), they respectively have a leg portion 141L and a spring portion 142L, and a leg portion 141R and a spring portion 142R.
The storage spring (elastic member) 15L is a metal member with spring properties, and as shown in Fig. 2(b), includes an upper surface portion 151L, a leaf spring portion 152L, a mounting member fixing portion 153L, a terminal block fixing portion 154L, a terminal block mounting screw hole 157L, a ground wire mounting screw hole 158L, and mounting member fixing screw holes 159a and 159b. The storage spring 15R has the same configuration as the storage spring 15L (not shown). Hereinafter, the terminal block fixing portions 154L and 154R may be referred to as "terminal block fixing portions 154".
1(a) and 2(a), the cap member 13L is a metal member that serves as a lid to prevent the cover member 12 from coming off when the cover member 12 is attached to the mounting member 11. The cap member 13L is disposed on the left side of the mounting member 11, and the cap member 13R is disposed on the right side of the mounting member 11, as shown in FIG.

Hereinafter, the cap members 13L and 13R will be referred to as the "cap members 13", the mounting springs 14L and 14R will be referred to as the "mounting springs 14", the storage springs 15L and 15R will be referred to as the "storage springs 15", the terminal blocks 162L and 162R will be referred to as the "terminal blocks 162", the earth wires 164L and 164R will be referred to as the "earth wires 164", the earth connectors 163L and 163R will be referred to as the "earth connectors 163", the side wall convex portions 112L and 112R will be referred to as the "side wall convex portions 112", the legs 141L and 142R will be referred to as the "legs 141", the spring portions 142L and 142R will be referred to as the "spring portions 142", and the opening outer edge portions 72a and 72b will be referred to as the "opening outer edge portions 72".
The spring portion 141 and the leg portion 142 may be separate members.

The cover member 12 is a translucent resin member. The power supply unit 161 is a device that supplies power to the LEDs 19. The printed circuit board 18 is an electronic component on which the LEDs 19, which are light sources, are mounted. The terminal block 162 is a general terminal block that connects a power line for supplying power to the power supply unit 161. The terminal block 162 has a power supply insertion port 162H. The power supply insertion port 162H collectively refers to the power supply insertion port 162HL and the power supply insertion port 162HR on the right side of the terminal block 162H located on the left side of the lighting fixture 1 shown in FIG. 1(a).

The electrical connections are as follows:
3A, the external power line 6 is connected to a terminal block 162L. Next, power is supplied from the terminal block 162L to a power supply device 161 via a power supply wiring 16WL. The power supply device 161 supplies power via a path of the printed circuit board 18 and the LED 19.
On the other hand, terminal block 162L is connected to terminal block 162R, which is separate from power supply device 161, and is used for outward wiring. Outward wiring is a wiring method that is generally used when arranging long lighting fixtures in a line.

The earth connector 163 is connected to an earth wire 164, and is a connector for connecting a general earth wire associated with electrical work on lighting fixtures. The earth wire is connected to the outer casing of the lighting fixture 1 via the earth connector 163, earth wire 164, earth mounting screw 165, elastic member 15, and mounting member 11. As a result, the earth wire and lighting fixture 1 are conductor-connected and grounded. The earth connector 163, earth wire 164, and earth wire mounting screw 165 have the same function as a general ground terminal, and as long as they can be grounded, their configuration is arbitrary.

The storage section C is a space surrounded by the bottom surface 111, the side wall protrusions 112, and the "top surface of the mounting member 11" (the semi-transparent gray colored area in FIG. 5). It is sufficient for the storage section C to have a volume large enough to accommodate at least a portion of the terminal block. For example, a part other than the mounting member 11 may be erected on the bottom surface to serve as a side surface that defines the volume of the storage section C.

<Structure description>
2(a), the mounting spring (hook member) 14L is attached to the bottom surface 111 of the mounting member 11 with mounting spring mounting screws S4La, S4Lb, S4Lc, and S4Ld, and the storage spring 15L is attached with storage spring mounting screws S5La and S5Lb. Hereinafter, the mounting spring mounting screws S4La, S4Lb, S4Lc, and S4Ld as well as the other mounting spring mounting screws may be collectively referred to as the "mounting spring mounting screws S4."

2(a) and 2(b), the upper surface 151L of the storage spring 15L is bent so that the terminal block fixing portion 154L is erected on the upper surface 151L. A terminal block 162L and an earth connector 163L are arranged on the upper surface 151L. The terminal block 162L is fixed to the terminal block fixing portion 154L by a terminal block mounting screw 166L and a nut 167L. By arranging the terminal block 162L in this manner, the depth of the terminal block 154L can be shortened, and the terminal block 154L can be easily accommodated in the accommodation portion C.
The terminal block 162 is arranged such that the two power supply insertion ports 162H are arranged next to each other in the same direction as the mounting direction of the lighting fixture 1. Fig. 1(b) shows the two power supply insertion ports 162HR of the right-side terminal block 162R arranged next to each other, and the left-side power supply insertion port 162HL is arranged in the same manner (the left-side power supply insertion port 162HL is not shown).
In this embodiment, the terminal block fixing portion 154L is formed by bending, but it is sufficient that it is provided upright on the upper surface portion 151L, and it may be a separate part from the upper surface portion 151L.
Moreover, an earth wire 164L is connected to the earth connector 163L, and the earth wire 164L is fixed to the upper surface by an earth mounting screw 165L.
FIG. 2(a) is an enlarged view of the left side of the lighting fixture 1, and the right side of the lighting fixture 1 has a similar structure to the left side.

The power supply unit 161 is slid into the mounting member 11. At this time, pad 16PL is attached close to the mounting member 11 to prevent the power supply unit 161 from sliding leftward, and pad 16PR is similarly attached to the rightward sliding direction. (The rightward sliding direction is not shown.) Therefore, the power supply unit 161 is held in the mounting member 11 without moving in the sliding direction.

<Installation>
Here, a manner in which the lighting fixture 1 is installed in the raceway 7 (when the opening 71 is arranged facing downward) will be described.
As shown in FIG. 3A, the mounting spring 14 is inserted into the opening 71, and the lighting fixture 1 is pushed into the raceway 7 to install it. At this time, the terminal block 162L is arranged in a state where it protrudes from the upper surface of the mounting member 11. This is a state where the terminal block 162L is outside the accommodation section C (semi-transparent gray colored section in FIG. 5) as shown in FIG. 5. With this arrangement, when connecting the power line 6 to the terminal block 162L, there are no obstacles such as the side surface of the mounting member 11 around the power line 6, compared to when the terminal block 162L is arranged in the accommodation section C, so that the operation of grabbing the power line 6 with fingers and connecting it to the terminal block 162L is easy. Here, the terminal block 162L may be arranged outside the accommodation section C to an extent that the operation of grabbing the power line 6 with fingers and connecting it to the terminal block 162L is possible when connecting the power line 6. The state in which the lighting fixture 1 is pressed against the raceway 7 from the state shown in Figure 3(a) is shown in Figure 3(b) when installation is completed, with the bottom surface of the raceway 7 and the top surface of the lighting fixture 1 positioned so close together that there is almost no gap between them.

As shown in Figures 4(a) and (b), the raceway 7 may be suspended from a hanging bolt 79 installed on a ceiling or the like when installed. As shown in Figures 4(a) and (b), 5, and 6, a hanging bracket 77 is attached to the raceway 7 so as to just surround its cross section, and a hole is provided at the top of the hanging bracket 77 so that the hanging bolt 79 can pass through it. The hanging bolt 79 is passed through the hole, and the hanging bracket 77 is fixed by clamping it with nuts 78U and 78D. The hanging bracket 77 is a component that is generally used when suspending a raceway. The number of hanging bolts and hanging brackets for one raceway is arbitrary.

As shown in Figures 4 (a) and 5, when the hanging bracket 77 is in a position that does not interfere with the terminal block 162L, the lighting fixture 1 can be installed on the raceway 7 with a portion of the terminal block 162L housed inside the raceway 7.
As shown in Figures 4 (b) and 6, when the hanging bracket 77 is in a position where it interferes with the terminal block 162L, the terminal block 162L is pushed downward by the hanging bracket 77, and the storage spring 15 deforms, moving toward the bottom surface 111, and the terminal block 162L is stored in the storage section C.
With this configuration, it is easy to connect the power line to the terminal block 162L, and the lighting fixture 1 can be installed close to the raceway 7 even if there is a member on the underside of the raceway 7 that interferes with the terminal block 162L. The "installation state" described here is for the left side of the lighting fixture 1, but the right side has a similar structure, and the "installation state" is also the same as the left side.

2. Second embodiment
Hereinafter, a lighting device 2 according to a second embodiment of the present invention will be described with reference to the drawings.
The second embodiment provides a lighting fixture that can be installed in a raceway in which the raceway 7 described in the first embodiment is installed upside down, i.e., with the opening on the upper side (this state is referred to as raceway 7U and is shown in Figure 7).
As shown in FIG. 7, the raceway 7U to be installed has an opening 71 and opening outer edge portions 72a and 72b.

The lighting fixture 2 in the second embodiment has almost the same configuration as the lighting fixture 1 in the first embodiment. The only difference between the two is that the mounting springs (hooking members) are mounting springs (hooking members) 24L and 24R (hereinafter collectively referred to as "mounting springs (hooking members) 24") that correspond to the raceway 7U. Here, the mounting springs 24, which are the difference between the two, will be mainly described.
As shown in Figures 8(a) and (b), the lighting fixture 2 comprises a mounting spring 24L, a spring portion 242L, and a leg portion 241L. Here, Figures 8(a) and (b) explain the left side of the lighting fixture 2. Although not shown, the right side of the lighting fixture 2 is similar to the left side and comprises a mounting spring 24R, a spring portion 242R, and a leg portion 241R. Hereinafter, the spring portions 242L and 242R will be referred to as the "spring portion 242", and the legs 241L and 241R will be referred to as the "leg portion 241".

<Installation>
Here, the manner in which the lighting fixture 2 is installed on the raceway 7U will be described.
As shown in Figure 9, the spring portion 242L is a member with spring properties, consisting of a bottom portion 243L formed by bending a plate-shaped member, side portions 244aL and 244bL standing approximately vertically from both ends of the bottom portion, and hook portions 245aL and 245bL formed by bending the upper ends of both sides into a hook shape, and is processed to be slightly larger than the width of the raceway 7U and is attached so as to sandwich the raceway 7U.

In the second embodiment, the opening 71 of the raceway 7U to be installed faces upward, so there is no opening on the lower side. As shown in Figures 8(a) and (b), in this installation state, the lower side of the raceway 7U and the terminal block 162L interfere with each other regardless of the position of the hanging metal fitting 77.
In this case, as in the first embodiment when the hanging bracket 77 interferes with the terminal block 162L, the terminal block 162L is pushed downward by the raceway 7U, and the storage spring 15 deforms, moving toward the bottom surface 111, and the terminal block 162L is accommodated in the accommodation section C.

The power supply is connected to the lighting fixture 2 before the mounting spring 24 is attached to the raceway 7U. The terminal block 162L is arranged in a protruding state on the upper surface of the mounting member 11, so that when connecting the power line 6 to the terminal block 162L, as in the first embodiment, there are no obstacles such as the side surface of the mounting member 11 around the power line, and compared to when the terminal block is arranged in the housing C, the operation of grasping the power line 6 with the fingers and connecting it to the terminal block 162 is easy. As shown in Figures 8 (a) and (b) when the installation is completed, the underside of the raceway 7 and the upper surface of the lighting fixture 1 are arranged close to each other with almost no gap between them.

This configuration makes it easy to connect the power line to the terminal block 162L, and allows the lighting fixture 1 to be installed close to the raceway 7 even if there is a member on the underside of the raceway 7U that interferes with the terminal block 162L. The "installation state" described here is for the left side of the lighting fixture 2, but the right side has a similar structure and the "installation state" is also the same.

3. Modifications
The lighting fixtures in the respective embodiments are merely examples and can be modified, and will be described below with reference to examples.
<First Modification>
In each embodiment, the terminal block 162 is fixed to the terminal block fixing portion 154 and the terminal block is pressed, but it is sufficient if the portion accommodated in the accommodation portion C increases as the terminal block moves, and the portion that is pressed is not limited to the terminal block 162. For example, as shown in Fig. 10, the height of the terminal block fixing portion 154 may be made higher than the height of the terminal block 162 to form a terminal block fixing portion 154Lv (similarly 154Rv on the right side), and the terminal block fixing portion 154Lv may be pressed. Regardless of whether the terminal block or the terminal block fixing portion is pressed, a cushioning material may be used appropriately in the portion that is pressed.

<Second Modification>
In each embodiment, the mounting spring 24 is fixed to the mounting member 11 by the mounting screw S4, but it is sufficient if it is held directly or indirectly to the mounting member 11. For example, a rail portion may be provided along the longitudinal direction of the mounting member 11, the mounting spring may be processed so as to be insertable into the rail portion, and the mounting spring may be inserted into the rail to hold the mounting spring on the mounting member. With this configuration, the mounting spring can be moved in the longitudinal direction of the lighting fixture, and even if a member that interferes with the lighting fixture, such as a hanging bracket, is present on a rail-shaped member such as a raceway, a lighting fixture can be provided that can be attached by avoiding the interfering member.

<Third Modification>
In each embodiment, the device is attached to the raceway by a mounting spring (hook member), but the installation target is not limited to a raceway, and may be a substantially flat surface such as a ceiling, wall, floor, etc. When the installation target is a flat surface, appropriate methods may be used, such as providing a hole for the mounting spring (hook member) in the installation surface or using a screw holder for screwing the device to the installation surface.
