The building material in which the lighting fixture 1 is installed is not limited to the wall, and the lighting fixture 1 may be installed in a building material other than the wall such as a ceiling or a floor.

As shown in FIGS. 7 to 10, the light source unit 3 includes two LED modules 4, a lighting device 5, a housing 6, a cover 7, and two end members 8.

Each of the two LED modules 4 includes an LED (Light Emitting Diode) 40, an LED board 41 having a plurality of LEDs 40 mounted on the front surface (front surface), and a plurality of receptacle connectors 42 mounted on the front surface of the LED board 41. It has the electric wire 43 of. However, in this embodiment, the cover 7 is a component of the LED module 4.

The LED substrate 41 is formed in a long rectangular flat plate shape with the left-right direction as the longitudinal direction by, for example, an insulating substrate made of resin such as a glass cloth base material epoxy resin substrate. However, the two LED boards 41 have different dimensions in the longitudinal direction. Therefore, in the following description, the LED module 4 having the longer longitudinal dimension of the LED substrate 41 is referred to as the first LED module 4A, and the LED module 4 having the shorter longitudinal dimension of the LED substrate 41 is referred to as the first LED module 4A. It may be called the LED module 4B of 2. The LED module according to this embodiment is the first LED module 4A. Further, the substrate according to this embodiment is the LED substrate 41 of the first LED module 4A.

The LED 40 is, for example, a white LED for lighting. However, the LED 40 may be an organic light emitting diode (Organic Light Emitting Diode). The LEDs 40 are mounted so as to be arranged in a row at equal intervals along the longitudinal direction (horizontal direction) of the LED substrate 41 at the center of the LED substrate 41 in the lateral direction (vertical direction) (see FIGS. 10 and 11). ).

A total of four receptacle connectors 42 (42A, 42B, 42C, 42D) are mounted on the front surface of the LED substrate 41 of the first LED module 4A. Two of the four receptacle connectors 42A to 42D, the receptacle connectors 42A and 42B are separately mounted on the upper and lower sides of the LED 40 on the front surface of the right end of the LED board 41 of the first LED module 4A.

The remaining two receptacle connectors 42C and 42D are mounted vertically side by side under the LED 40 on the front surface of the LED substrate 41 of the first LED module 4A in the center in the longitudinal direction. However, the two receptacle connectors 42C and 42D are mounted so as to be offset in the left-right direction (see FIGS. 10 and 11).

In the LED board 41 of the first LED module 4A, three slits 44 (44A, 44B, 44C) are arranged in a row in the left-right direction at the lower end portion closer to the center (to the right) than the two receptacle connectors 42C and 42D. It is provided (see FIGS. 10 and 11). An electric wire 43 (two electric wires 43C and 43D described later) is inserted into each of these three slits 44.

The leftmost slit (hereinafter, also referred to as the first slit) 44A is formed in an L shape. The open end 440 of the first slit 44A is provided on the lower edge of the LED substrate 41. The closed end 441 of the first slit 44A is provided on the LED substrate 41 on the right side of the open end 440 of the first slit 44A (see FIG. 11). In other words, the first slit 44A is formed on the LED substrate 41 so that the open end 440 of the first slit 44A is closer to the two receptacle connectors 42C and 42D with respect to the closed end 441 of the first slit 44A. There is.

The central slit (hereinafter, also referred to as a second slit) 44B and the rightmost slit (hereinafter, also referred to as a third slit) 44C are both formed in a rectangular shape. Both the open end 440 of the second slit 44B and the open end 440 of the third slit 44C are provided on the lower edge of the LED substrate 41. Further, both the closed end 441 of the second slit 44B and the closed end 441 of the third slit 44C are provided at positions near the center of the LED substrate 41 (see FIG. 11).

Two receptacle connectors 42 (42E, 42F) are mounted on the front surface of the LED board 41 of the second LED module 4B. The two receptacle connectors 42E and 42F are separately mounted on the upper and lower sides of the LED 40 on the front surface of the left end of the LED board 41 of the second LED module 4B.

One of the plurality of wires 43 (43A, 43B, 43C, 43D) (four in the illustrated example) is the receptacle connector 42A of the first LED module 4A and the receptacle connector 42E of the second LED module 4B. And are electrically connected (see FIG. 10).

Further, the electric wire 43B electrically connects the receptacle connector 42B of the first LED module 4A and the receptacle connector 42F of the second LED module 4B. That is, the plurality of LEDs 40 of the first LED module 4A and the plurality of LEDs 40 of the second LED module 4B are electrically connected by two electric wires 43A and 43B and four receptacle connectors 42A, 42B, 42E and 42F. It is connected.

One of the remaining two electric wires 43C and 43D, the electric wire 43C, electrically connects the receptacle connector 42C of the first LED module 4A and the plug connector 45. The other electric wire 43D electrically connects the receptacle connector 42D of the first LED module 4A and the plug connector 45 (see FIG. 10). Here, each of the two electric wires 43C and 43D is a coated electric wire formed by coating an insulator such as vinyl resin on a conductor made of a single wire or a stranded wire. The surfaces of the insulators of the two electric wires 43C and 43D are separately colored in two different colors (for example, white and black) in order to distinguish between the positive pole and the negative pole. Of the two electric wires 43C and 43D, the electric wire 43D whose insulator surface is colored white is closer to the LED 40 than the electric wire 43C whose insulator surface is colored black (LED substrate 41). (See FIG. 10).

These two electric wires 43C and 43D are inserted from the front to the rear through the first slit 44A at the left end, then from the rear to the front through the second slit 44B at the center, and further, the third slit at the right end. It is inserted through 44C from the front to the rear (see FIG. 10). Since the first slit 44A is formed in an L shape, the bending angle of the electric wires 43C and 43D becomes small in the state of being inserted into the first slit 44A, and the bending angle is generated in the electric wires 43C and 43D corresponding to the bending angle. Bending stress can be reduced. As a result, in the first LED module 4A, the stress applied to the receptacle connectors 42C and 42D from the electric wires 43C and 43D can be reduced, and the deterioration of the joint portion between the receptacle connectors 42C and 42D and the LED substrate 41 can be suppressed. ..

Further, the first slit 44A is formed on the LED substrate 41 so that the open end 440 of the first slit 44A is closer to the receptacle connectors 42C and 42D with respect to the closed end 441 of the first slit 44A (FIG. 11). Therefore, in the first LED module 4A, the electric wires 43C and 43D inserted through the first slit 44A can be separated from the open end 440 of the first slit 44A. As a result, in the first LED module 4A, the electric wires 43C and 43D inserted through the first slit 44A are difficult to move from the open end 440 of the first slit 44A to the outside of the first slit 44A.

Here, the LED substrate 41 tension-stops the two electric wires 43C and 43D by inserting them into the even number (two) of the second and third slits 44B and 44C. Therefore, the LED substrate 41 can reduce the stress applied to the receptacle connectors 42C and 42D from the electric wires 43C and 43D, and can suppress deterioration of the joint portion between the receptacle connectors 42C and 42D and the LED substrate 41.

Similarly, the operator inserts the fixing screw 800, which is a tapping screw, into the through hole 600 provided at the right end of the bottom wall 60 of the housing 6. Then, the operator screwes the fixing screw 800 inserted through the through hole 600 into the screwing portion 840 of the second end member 8B, thereby screwing the second end member 8B to the housing 6 (FIG. 7). reference).

The assembly work of the light source unit 3 is completed by the above procedure. However, the above-mentioned assembly procedure is an example, and the order of some procedures can be changed.

By the way, a part of the electric wires 43C and 43D for supplying power from the lighting device 5 to the LED module 4 is arranged on the front surface of the LED board 41. Therefore, a part of the light emitted from the LED 40 is reflected on the surfaces of the electric wires 43C and 43D (the coated surface of the coated electric wire). Therefore, if the reflectance of the coated surface of the coated electric wire is significantly lower than the reflectance of the front surface of the LED substrate 41, the shadows of the electric wires 43C and 43D may be visible through the cover body 70. Therefore, in the LED module (first LED module 4A) of the present embodiment, the shadows of the electric wires 43C and 43D are made difficult to see by arranging the electric wire 43D having a white coating surface at a position close to the LED 40.

Here, in the light source unit 3, the material forming the cover 7 (polycarbonate resin) and the material forming the end member 8 (PBT resin) are different, and the lengthwise dimension of the cover 7 is the longitudinal direction of the end member 8. It is much larger (longer) than the size of. Therefore, in the light source unit 3, it is considered that the expansion amount of the cover 7 while the LED module 4 is lit is larger than the expansion amount of the end member 8. Therefore, if the first end portion 81 and the end portion of the cover 7 are in contact with each other while the LED module 4 is off, the cover 7 and the first cover 7 and the first cover 7 expand when the cover 7 is inflated while the LED module 4 is lit. Excessive stress may occur in the end portion 81.

Therefore, in the light source unit 3, the dimensions of the cover 7 and the like are designed so that a slight gap (for example, 1 mm to 2 mm) is provided between the first end portion 81 and the end portion of the cover 7 at room temperature. Therefore, even if the cover 7 thermally expands while the LED module 4 is lit, it becomes difficult for the end portion of the cover 7 to come into contact with the first end portion 81, so that excessive stress may occur between the cover 7 and the first end portion 81. The sex can be greatly reduced. However, if there is a gap between the end of the cover 7 and the first end 81, foreign matter such as dust or insects invades the light source unit 3 (in the space surrounded by the cover 7 and the LED module 4) through the gap. There is a risk of

Therefore, in the light source unit 3, the seal portions 30 are arranged between the first end portions 81 of the end members 8A and 8B and both ends of the cover 7 (FIGS. 7 and 10). The seal portion 30 is formed of, for example, a substantially semicircular ring of silicone rubber (see FIG. 10). The seal portion 30 is in close contact with the first end portion 81 and the cover 7 to seal the gap between the first end portion 81 and the cover 7 (see FIG. 7). By sealing the gap between the first end portion 81 and the cover 7, the sealing portion 30 suppresses the intrusion of foreign matter into the light source unit 3, and the stress generated at the end portion of the cover 7 and the first end portion 81 during thermal expansion. Can be reduced.

Next, the construction procedure of the lighting fixture 1 will be described.

The worker who performs the construction work first attaches the instrument main body 2 to the construction material (for example, a wall). The operator inserts a mounting screw such as a wood screw into the pair of mounting holes 206 of the main body 20 and screws the main body 20 to the wall.

Subsequently, the operator inserts the housing 6 of the light source unit 3 into the main body 20 from the front. The operator bends the pair of displacement portions 211 of the support member 21 outward by pushing the engaging portions 210 of the support member 21 at the upper and lower ends of the rear end of the housing 6. Then, the second displacement piece 211B and the engaging portion 210 of the displacement portion 211 pass through the opening 203 of the side portion 201 and are displaced to the outside of the side portion 201. However, the displacement of the second displacement piece 211B and the engaging portion 210 is regulated by the regulating portion 204 (regulating piece 2040).

Even after the pressing surface 2120 of the spring portion 212 of the support member 21 comes into contact with the rear surface of the housing 6 of the light source unit 3, the operator resists the spring force (pushing pressure) of the spring portion 212 and housings the housing in the main body portion 20. 6 is inserted. Then, when the engaging portion 210 of the support member 21 reaches the recess 610 of the side wall 61, the displaced displacement portion 211 that has been bent returns to the original state. Then, when the operator releases the light source unit 3, the housing 6 pressed by the spring portion 212 moves forward, and the engaging portion 210 of the support member 21 engages with the engaged portion 62 of the housing 6. It fits. In this way, the operator supports the housing 6 on the pair of support members 21 and attaches the light source unit 3 to the main body 20.

As described above, the operator can attach the light source unit 3 to the instrument main body 2 without using a tool such as a screwdriver. Therefore, the lighting fixture 1 can shorten the working time required for installation.

Here, the engaged portion 62 is provided over the entire length of the side wall 61 in the longitudinal direction, and is formed wider than the engaging portion 210 in the longitudinal direction of the housing 6. Therefore, the engaging portion 210 and the engaged portion 62 are movably engaged with each other along the longitudinal direction of the side wall 61. That is, the housing 6 of the light source unit 3 is supported by the support member 21 so as to be movable along the longitudinal direction of the main body portion 20 of the fixture main body 2 with respect to the fixture main body 2. Since the housing 6 is supported by the support member 21 so as to be movable along the longitudinal direction of the main body 20 in this way, excessive stress is applied from the support member 21 to the housing 6 when the housing 6 thermally expands. It can be prevented from being applied. However, the moving range of the housing 6 of the light source unit 3 (the moving range of the engaging portion 210 with respect to the engaged portion 62) is limited to the range in which the engaging portion 210 does not come into contact with the second end portion 82 of the end member 8. .. That is, in the lighting fixture 1 of the present embodiment, the second end portion 82 of the end member 8 corresponds to a limiting portion that limits the moving range of the engaging portion 210.

Next, the lighting system 10 of this embodiment will be described. The lighting system 10 has a plurality of lighting fixtures 1. However, the plurality of lighting fixtures 1 included in the lighting system 10 include several types of lighting fixtures 1 having different sizes (total lengths) in the longitudinal direction. For example, the lighting system 10 includes a standard length luminaire 1 (1A) and a luminaire 1 (1B) having twice the standard length, as shown in FIG. However, the two luminaires 1A and 1B have almost the same configuration except that the sizes (total length) in the longitudinal direction are different.

The two luminaires 1A and 1B are arranged side by side in a row along the longitudinal direction. Here, the fixture main body 2 of the lighting fixture 1A and the fixture main body 2 of the lighting fixture 1B are connected by a connecting portion 205 provided in the main body portion 20 of each fixture main body 2. The connecting portions 205 provided at both ends of the main body portion 20 in the longitudinal direction are symmetrical with respect to the center line along the longitudinal direction of the main body portion 20. Therefore, by engaging the connecting portions 205 of the main body portions 20 in the vertical direction and the horizontal direction, the two main body portions 20 can be mechanically connected to each other so as to be lined up in a row along the longitudinal direction. ..

Then, the light source units 3 of the lighting fixtures 1A and 1B are attached to the main body portions 20 fixed to the wall. In this case, the second power connector 56 of the luminaire 1A and the first power connector 53 of the luminaire 1B are electrically connected (FIG. 16). That is, AC power is supplied to the two lighting fixtures 1A and 1B by the feed wiring of the power supply line. Further, the first signal connector 505 of the luminaire 1A and the second signal connector 506 of the luminaire 1B are electrically connected. That is, the control signal is transmitted to the two lighting fixtures 1A and 1B by the feed wiring of the signal line.

Here, at both ends of the light source unit 3 in the longitudinal direction, the end portion of the cover 7 and a part of the end member 8 protrude outside the housing 6. Further, side portions 201 of the main body portion 20 are arranged outside both ends in the longitudinal direction of the housing 6. That is, the vertical movement range of the first power supply connector 53 and the second power supply connector 56 electrically connected to each other, and the first signal connector 505 and the second signal connector 506 electrically connected to each other It is regulated by a pair of side portions 201. Therefore, when viewed from the front, the first power supply connector 53, the second power supply connector 56, the first signal connector 505, and the second signal connector 506 do not protrude outside the fixture main body 2, and the appearance quality of the lighting system 10 is improved. It can be improved. Moreover, since the lighting fixture 1 (1A; 1B) does not require parts for regulating the moving range such as the first power connector 53, parts different from the fixture main body 2 and the light source unit 3 are required. It is possible to improve the workability of the construction work as compared with the case.

Further, the lighting system 10 has an incoming wire fitting 11 and a terminal fitting 12.

The vertical plate 1102 is provided with a first electric wire insertion port 1105 and a second electric wire insertion port 1106. The first electric wire insertion port 1105 is provided in the upper part of the vertical plate 1102. The second electric wire insertion port 1106 is provided at the lower part of the vertical plate 1102.

The incoming line cover 111 has a flat plate-shaped front plate 1110 and a pair of side plates 1111 protruding rearward from the upper and lower ends of the front plate 1110 (see FIG. 18). A screw insertion hole penetrates the front plate 1110. The wire entry cover 111 is fixed to the base metal fitting 110 by screwing the fixing screw 112 inserted into the screw insertion hole of the front plate 1110 into the female thread portion 1104 of the base metal fitting 110.

The terminating metal fitting 12 has a base metal fitting, a terminating cover 121, and a fixing screw 122 (see FIG. 19). The base metal fitting has substantially the same configuration as the base metal fitting 110 of the wire entry metal fitting 11.
