Further, the first engaging portion 91 and the second engaging portion 92 are grooves (upper groove 410A; 410B and lower) provided on both upper and lower edges of the first LED substrate 41A and the second LED substrate 41B, respectively. It is inserted one by one into the gutters 411A; 411B). As a result, the connecting member 9 does not protrude out of the first and second LED boards 41A and 41B in the lateral direction (vertical direction) of the first and second LED boards 41A and 41B, so that the light source device 15 can be used. It is possible to reduce the size.

Further, the upper wire holding portion 93 of the pair of wire holding portions 93 hooks the electric wire 43A for electrically connecting the receptacle connector 42A of the first LED board 41A and the receptacle connector 42E of the second LED board 41B.

Holds the electric wire 43B. Therefore, the light radiated from the LED 40 at the right end of the first LED board 41A and the LED 40 at the left end of the second LED board 41B is less likely to be radiated by the electric wires 43A and 43B.

Further, in the light source device 15, the pair of electric wire holding portions 93 are inserted into the first notch 46A and the second notch 46B, and the first and second LED substrates 41A and 41B are arranged in the lateral direction (vertical direction). It does not protrude outside the first and second LED substrates 41A and 41B. As a result, the light source device 15 does not protrude the pair of electric wire holding portions 93 out of the first and second LED substrates 41A and 41B, so that the size can be reduced.

The pair of side plate portions 85 project forward from both ends in the lateral direction (vertical direction) on the front surface of the bottom plate portion 84. Each side plate portion 85 is formed in a rectangular flat plate shape. Further, an engaging protrusion 850 is provided on the outer surface of each side plate portion 85. The engagement protrusion 850 projects linearly from the rear end portion on the outer surface of the side plate portion 85 over the entire length in the longitudinal direction (left-right direction) of the side plate portion 85 (see FIG. 10).

Next, the assembly procedure of the light source device 15 will be described. First, the worker who performs the assembly work inserts the pair of first engaging portions 91 of the connecting member 9 into the upper groove 410A and the lower groove 411A of the first LED board 41A one by one from the rear, and the first LED. A pushing force is applied to the connecting member 9 so as to approach the substrate 41A. Then, it is pushed by the edge of the first LED substrate 41A and the pair of first engaging portions 91 bends outward so as to be separated from the first LED substrate 41A. Then, when the tip of each first engaging portion 91 gets over the edge of the first LED substrate 41A, each of the bent first engaging portions 91 returns to the original state, and each first engaging portion 91 becomes the first. 1 engages with the edge of the LED substrate 41A. Further, the operator inserts a pair of second engaging portions 92 of the connecting member 9 into the upper groove 410B and the lower groove 411B of the second LED board 41B one by one from the rear, and brings them closer to the second LED board 41B. A pushing force is applied to the connecting member 9 as described above. Then, it is pushed by the edge of the second LED board 41B and the pair of second engaging portions 92 bends outward so as to be separated from the second LED board 41B. Then, when the tip of each second engaging portion 92 gets over the edge of the second LED substrate 41B, each of the bent second engaging portions 92 returns to the original state, and each second engaging portion 92 becomes a second. 2 engages with the edge of the LED substrate 41B. In this way, the first LED substrate 41A and the second LED substrate 41B are connected by the connecting member 9 in a state of being arranged along the longitudinal direction.

Subsequently, the operator electrically connects the electric wire 43A to the receptacle connector 42A of the first LED board 41A and the receptacle connector 42E of the second LED board 41B, respectively, and then connects the electric wire 43A to the upper electric wire holding portion 93. Hold it. Further, the operator electrically connects the electric wire 43B to the receptacle connector 42B of the first LED board 41A and the receptacle connector 42F of the second LED board 41B, respectively, and then connects the electric wire 43B to the lower electric wire holding portion 93. Hold it.

Subsequently, the operator connects the electric wire 43C to the receptacle connector 42C of the first LED board 41A, and connects the electric wire 43D to the receptacle connector 42D of the first LED board 41A. The operator inserts these two electric wires 43C and 43D into the three electric wire insertion grooves 44A to 44C and causes the first LED substrate 41A to hold the electric wires 43C and 43D.

The assembly work of the light source device 15 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, in the light source device 15, the second LED board 41B may have the same structure as the first LED board 41A. The first LED substrate 41A is provided with an upper groove 410A and a lower groove 411A at both ends in the longitudinal direction (left-right direction) (see FIG. 10). Further, although not shown in FIG. 10, the first LED substrate 41A has two receptacle connectors mounted on the left end portion as well as the right end portion. The two receptacle connectors 42A, 42B at the right end of the first LED board 41A located on the left side and the left end of the first LED board 41A (corresponding to the second LED board) placed on the right side. The two receptacle connectors of the unit are electrically connected by two electric wires 43A and 43B. However, since the electrical polarities of the two receptacle connectors 42A and 42B are different, it is necessary to correctly combine and connect the two receptacle connectors 42A and 42B of the first LED substrate 41A.

Therefore, the two first LEDs are connected to the connecting member 9 and the first LED board 41A, respectively, so that the two receptacle connectors 42A and 42B of the two first LED boards 41A are connected in the correct combination. A structure is provided to regulate the orientation of the substrates 41A. Specifically, in the connecting member 9, the distance S1 between the first engaging portion 91 and the second engaging portion 92 supported on the upper portion of the support portion 90 is supported on the lower portion of the support portion 90. The distance between the engaging portion 91 and the second engaging portion 92 is larger than the distance S2 (see FIG. 12). Further, the distance from the longitudinal end of the first LED substrate 41A to the upper groove 410A is larger than the distance from the longitudinal end of the first LED substrate 41A to the lower groove 411A (see FIG. 12). ). Therefore, unless the upper grooves 410A of the two first LED boards 41A are arranged so as to be adjacent to each other along the longitudinal direction of the first LED board 41A, the light source device 15 has two pieces by the connecting member 9. It is configured so that the first LED substrate 41A cannot be connected. Therefore, the light source device 15 can prevent the first LED substrate 41A and the first LED substrate 41A corresponding to the second LED substrate from being connected by the connecting member 9 in the wrong direction.

Next, the procedure for assembling the light source unit 3 will be described. However, the attachment of the second power supply connector 56 and the signal cable 503 to the second end portion 82 of the first end member 8A, and the first power supply line 52 and the signal cable 504 to the second end portion 82 of the second end member 8B. Installation has been completed in advance.

First, the worker who performs the assembly work inserts the end portion of the LED board 41 between one end (for example, the left end) of the cover 7 and the pair of projecting pieces 720 of the holding portion 72, whereby the holding portion 72 of the cover 7 is inserted. Holds the LED module 4 (light source device 15) (see FIGS. 7 and 8). At this time, the projecting piece 720 on the rear side of the cover 7 is sandwiched between the first LED substrate 41A and the second LED substrate 41B and the two pairs of protrusions 94 (see FIG. 15). Further, the operator inserts the left end portion of the cover 7 between the pair of side surface portions 831 and the protrusion 86 of the first end member 8A.

Subsequently, the operator connects the plug connector 45 of the LED module 4 to the output connector 500 of the lighting device 5. Further, the operator connects the second power supply line 55 connected to the second power supply connector 56 to the second terminal block 54 of the lighting device 5 and controls the signal cable 503 connected to the first signal connector 505. Connect to the connector 501. Further, the operator connects the first power supply line 52 connected to the first power supply connector 53 to the first terminal block 51 of the lighting device 5 and lights the signal cable 504 connected to the second signal connector 506. It is connected to the control connector 502 of the device 5.

Next, the operator houses the lighting device 5 and the cover 7 holding the LED module 4 in the housing 6. First, the operator inserts the hooking portion 73 of the cover 7 from the left end of the housing 6, engages the hooking portion 73 with the engaging protrusion 64 of the housing 6, and attaches the cover 7 to the housing 6. Further, the operator engages the pair of protrusions 841 of the first end member 8A into the pair of mating holes 507 provided at the left end of the circuit board 50 from the rear. The operator inserts the upper and lower ends of the circuit board 50 of the lighting device 5 into the engagement groove 63 of the housing 6 from the left end of the housing 6, and the end of the circuit board 50 is inserted into the engagement groove 63 of the housing 6. The lighting device 5 is attached to the housing 6 by engaging the portions (see FIGS. 7 and 8). Further, the operator inserts the engaging protrusion 850 provided on the outer surface of the pair of side plate portions 85 of the first end member 8A into the engaging groove 63 of the housing 6, and the worker inserts the engaging groove of the housing 6. The engagement protrusion 850 of the first end member 8A is engaged with 63, and the first end member 8A is attached to the left end of the housing 6. Further, the operator inserts the front end portion of each side wall 61 of the housing 6 into the space created between the pair of protrusions 86 of the first end member 8A and the pair of leg portions 71 of the cover 7.

Subsequently, the operator inserts the right end portion of the cover 7 between the pair of side surface portions 831 and the protrusion 86 of the second end member 8B. Further, the operator inserts the engagement protrusion 850 provided on the outer surface of the pair of side plate portions 85 of the second end member 8B into the engagement groove 63 of the housing 6, and the worker inserts the engagement groove of the housing 6. The engagement protrusion 850 of the second end member 8B is engaged with 63, and the second end member 8B is attached to the right end of the housing 6.

Finally, the operator screwes the end member 8 to the housing 6. Specifically, the operator inserts the fixing screw 800, which is a tapping screw, into the through hole 600 provided at the left 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 first end member 8A, thereby screwing the first end member 8A to the housing 6 (FIG. 7). reference). 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.

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.

The spring portion 212 is formed in a substantially C shape when viewed from the front (see FIGS. 10 and 16). The spring portion 212 projects from the left-right end of the plate portion 214 in a direction away from the plate portion 214. Both arms of the spring portion 212 are curved so as to gradually project forward as they move away from the plate portion 214. The tip portion of the spring portion 212 connecting both arms of the spring portion 212 gently protrudes forward. The tip of the spring portion 212 has a pressing surface 2120 that presses the housing 6 and a curved surface 2121 that is curved so as to increase the distance from the housing 6 as the distance from the pressing surface 2120 increases (FIG. FIG. 7).

The mating portion 213 has a first mating piece 2131, a second mating piece 2132, a third mating piece 2133, a fourth mating piece 2134, and a mating claw 2135 (FIG. See 1). However, the first mating piece 2131, the second mating piece 2132, the third mating piece 2133, the fourth mating piece 2134, and the mating claw 2135 are processed by cutting and raising the plate portion 214.

Then, when the support member 21 is moved in parallel with the bottom portion 200 of the main body portion 20, the mating claw 2135 cut up from the first mating piece 2131 is inserted into the third mating hole 202C of the main body portion 20 from the rear. Will be inserted. Further, when the support member 21 is moved in parallel with the bottom portion 200 of the main body portion 20, the second mating piece 2132 moves to the side of the second mating hole 202B and comes into contact with the rear surface of the bottom portion 200. That is, the support member 21 regulates the movement with respect to the bottom portion 200 by mating the mating claw 2135 with the third mating hole 202C, and the second mating piece 2132 and the third mating piece 2133 and the fourth. It is fixed to the main body 20 by sandwiching the bottom 200 with the mating piece 2134. In the state where the support member 21 is fixed to the main body 20, the engaging portion 210 of the support member 21 and the second displacement piece 211B face each other in the vertical direction with the opening 203 of the side portion 201 of the main body 20. ing.

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

The worker who performs the construction work first attaches the instrument 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.
