(2-6) Assembling Step of Light Source Unit Next, the assembling process of the light source unit 2 will be described.

(2-6-1) A step of attaching the power supply unit and the signal terminal block to the support member First, at substantially the center of the upper surface of the main portion 210 of the support member 21, both ends of the power supply case 51 in the longitudinal direction are fixed screws 56, respectively. The power supply unit 5 is attached to the support member 21 by being screwed to the main portion 210 (see FIGS. 8 and 9). At this time, the open surface of the power supply case 51 is closed by the main portion 210 (see FIG. 9). Further, the power supply case 51 is formed by cutting and raising a hook piece 510 projecting outward (see FIG. 9). Then, the hook piece 510 is hooked on the hook portion 31 of the side wall portion 211 to prevent the power supply case 51 from floating from the main portion 210 of the support member 21. The screw portion 560 of the two fixing screws 56 for fixing the power supply case 51 to the main portion 210 slightly protrudes from the surface (lower surface) of the main portion 210 (see FIG. 9).

Further, the two signal terminal blocks 52 are attached to the upper surface of the main portion 210 of the support member 21 by the two attachments 23 (see FIGS. 8 and 10). Each fixture 23 has a fixing portion 230 to which the signal terminal block 52 is fixed, and a screwing piece 231 screwed to the main portion 210. A step is formed between the fixed portion 230 and the screwed piece 231, and in a state where the screwed piece 231 is screwed to the main portion 210 with the fixing screw 26, there is a space between the fixed portion 230 and the main portion 210. It is formed (see FIG. 10). A V-shaped protrusion 233 is provided at the end of the fixing portion 230, and the protrusion 233 is hooked on the protrusion 215 provided on the side wall portion 211 of the support member 21, thereby fixing the fixing portion 230. Is supported by the side wall portion 211 (see FIG. 10). The two signal terminal blocks 52 and the power supply unit 5 are each connected by two signal lines 53 (see FIG. 8).

The fixing portion 230 is provided with a mounting portion 232 to which a hanging member is attached. Then, the lower end of the hanging member is attached to the attachment portion 232. The hanging member is made of, for example, a string made of a chemical fiber or the like, and is used when the light source unit 2 is attached to the instrument main body 1.

(2-6-2) Step of Attaching the Light Source Module to the Support Member Subsequently, the light source module 20 is attached to the lower surface of the main portion 210. First, the worker who performs the mounting work installs the support member 21 upside down (with the lower surface of the main portion 210 facing up). Then, the operator inserts the end portion H1 (one end portion along the longitudinal direction) of the substrate 200 of the light source module 20 into the space between the locking piece 213 and the surface (lower surface) of the main portion 210 (FIG. 11). At this time, in order to facilitate the insertion of the end portion H1 of the substrate 200, the portion of the locking piece 213 facing the facing surface (lower surface) of the main portion 210 is tilted with respect to the facing surface of the main portion 210. It has been formed.

The operator inserts the end portion H1 of the substrate 200 into the space between the main portion 210 and the locking piece 213 as far as it will go, and then drops the end portion H2 on the opposite side of the substrate 200 into the inside of the positioning piece 212 (FIG. 11). As a result, in the substrate 200, one end H1 is locked to the locking piece 213, and the other end H2 faces the positioning piece 212, so that the substrate 200 is in the front-rear direction with respect to the main portion 210 (short of the substrate 200). Movement in the manual direction) and the vertical direction (thickness direction of the substrate 200) is restricted.

Then, the operator inserts the stepped screw 25 into the notch provided at the end H2 opposite to the end H1 of the substrate 200 locked to the locking piece 213. Further, the operator sandwiches the end portion H2 of the substrate 200 between the stepped screw 25 and the main portion 210 by tightening the stepped screw 25 in the screw hole provided in the main portion 210 (FIGS. 12 and 12). See 13). However, the head 250 of the stepped screw 25 is in contact with the tip of the positioning piece 212 of the main portion 210, and there is a slight gap between the head 250 and the end H2 of the substrate 200 of the light source module 20 (FIG. See 13). That is, the stepped screw 25 does not directly contact the substrate 200 of the light source module 20 to fix the substrate 200, but restricts the movement of the end portion H2 of the substrate 200 in the thickness direction (downward) by the head 250. By doing so, the light source module 20 is fixed to the main portion 210. The light source module 20 is electrically connected to the power supply unit 5 through a through hole provided in the main portion 210.

Then, in the light source unit 2, the end portion H1 of the substrate 200 is inserted between the locking piece 213 and the main portion 210 from the lateral direction of the substrate 200, and the end portion H2 on the opposite side of the substrate 200 is stepped. The light source module 20 is attached to the support member 21 by fixing it to the main portion 210 with screws 25. Therefore, as compared with the conventional example described in Patent Document 1, the work of moving the light source module 20 along the longitudinal direction of the light source module 20 is unnecessary, so that the workability of the assembly work can be improved.

(2-6-3) Cover Mounting Step to Support Member Subsequently, the cover 22 mounting portion 222 is inserted into the gap between the lower surface of the main portion 210 and the cover mounting piece 214 from one end in the longitudinal direction of the cover 22. As a result, the cover 22 is attached to the main portion 210 (see FIG. 10). Since the cover 22 is merely hooked on the cover mounting piece 214 of the main portion 210, the cover 22 can move with respect to the main portion 210 along the longitudinal direction of the main portion 210.

(2-6-4) End member attachment process First, the seal member 7 is attached to the cover end portion 60. Then, the cover end portion 60 and the end cap portion 61 are coupled. Subsequently, the fixture 62 is attached to the end cap portion 61.

The end member 6 assembled as described above is attached to both ends of the support member 21 and the cover 22 in the longitudinal direction one by one. Specifically, a part of the fixture 62 is inserted between the upper surface of the main portion 210 and the pair of protrusions 215. Then, the fixing plate is screwed to the main portion 210 of the support member 21.

Further, the cover end portion 60 and the seal member 7 are inserted into the cover 22, and both ends of the support member 21 in the longitudinal direction are closed by the end cap portion 61. The seal member 7 inserted into the cover 22 closes the gap between the cover end portion 60 and the cover 22 by being in close contact with the inner side surfaces of the front wall 220 and the side wall portion 211 of the cover 22.

As described above, the assembly of the light source unit 2 is completed by attaching one end member 6 to both ends of the support member 21 and the cover 22 in the longitudinal direction.

(2-7) Construction procedure of lighting equipment Next, the procedure of construction work for attaching the lighting equipment A1 to the ceiling will be described. The worker who performs the construction work inserts the power cable 80 pulled out into the room from the hole provided in the ceiling into the first electric wire hole 12 of the instrument main body 1. Further, the operator inserts the signal cable drawn into the room from the hole provided in the ceiling into the second electric wire hole 13. Then, the worker inserts two hanging bolts protruding downward from the ceiling into the two bolt insertion holes 14 of the instrument main body 1 one by one, tightens nuts to each hanging bolt, and attaches the instrument main body 1 to the ceiling. .. Further, the operator connects the power cable 80 to the power terminal block 15.

Subsequently, the operator hooks the tips of the two hanging members attached to the respective attachment portions 232 of the two attachments 23 into the two hook holes 18 of the instrument main body 1, one by one, thereby causing the light source unit 2 to be hooked. Is temporarily fixed by hanging it on the instrument body 1 with two hanging members. In this temporarily fixed state, the operator connects the receptacle connector 55 of the power supply unit 5 to the plug connector 16 of the instrument main body 1. Further, the operator connects the signal line of the signal cable inserted into the second electric wire hole 13 of the instrument main body 1 to the signal terminal block 52.

Then, the operator approaches the fixture body 1 while supporting the light source unit 2 in the temporarily fixed state with both hands, and inserts the mounting spring 30 of the fixture body 1 between the pair of side wall portions 211 of the support member 21. At this time, the mounting spring 30 is securely inserted between the pair of side wall portions 211 by the tip of the side wall portion 211 hitting the guide piece 400 of the guide member 40. Therefore, it is possible to prevent the spring piece 300 of the mounting spring 30 from coming out to the outside of the side wall portion 211 and causing a defect such as plastic deformation due to an excessive force applied to the spring piece 300.

Further, since the deformation amount (deflection amount) of the spring piece 300 is limited by the limiting member 41, it is possible to prevent the occurrence of a defect such as plastic deformation due to an excessive force applied to the spring piece 300.

In the mounting spring 30 inserted between the pair of side wall portions 211, the tip portions of the pair of spring pieces 300 are hooked on the hooking portion 31 on the inner surface of each side wall portion 211 (see FIG. 9). That is, the light source unit 2 is attached to the instrument main body 1 by the attachment member 3 including the two attachment springs 30 and the hook portion 31 (see FIGS. 1 and 2). If the operator pulls the light source unit 2 downward, the tip portion of the mounting spring 30 is disengaged from the hooking portion 31, so that the light source unit 2 can be removed from the instrument main body 1.

(3) Features of the Embodiment One feature of the light source unit 2 is a protruding portion (locking piece 213) that forms a space in which the end portion H1 of the substrate 200 can be inserted between the light source unit 2 and the facing surface (lower surface) of the main portion 210. ) Is held in the support member 21, and another end portion H2 of the substrate 200 is fixed to the main portion 210 by the fixing member.

According to the above features, it is possible to simplify the mounting work of the board 200 (light source module 20) to the support member 21 as compared with the case where the ends on both sides of the board are hooked and mounted on the support member. As a result, the light source unit 2 can improve the workability of the assembly work as compared with the conventional example. In the embodiment, the stepped screw 25 is used as a fixing member, but a screw other than the stepped screw may be used, or a member (part) other than the screw such as a caulking stud or double-sided tape may be used as a fixing member. do not have.

Here, the protruding portion (locking piece 213) protrudes from one end of the main portion 210 in the lateral direction along the longitudinal direction of the main portion 210 (see FIG. 12). Then, one end H1 in the lateral direction of the substrate 200 is inserted into the space between the locking piece 213 and the main portion 210 (see FIGS. 11 to 13). Therefore, when the light source unit 2 locks the end portion H1 of the substrate 200 to the locking piece 213 of the support member 21, the light source unit 2 may move the substrate 200 with respect to the support member 21 along the lateral direction of the substrate 200. good. Therefore, the light source unit 2 shortens the moving distance of the substrate 200 with respect to the support member 21 as compared with the case where the substrate 200 is moved with respect to the support member 21 along the longitudinal direction of the substrate 200, and the workability of the assembly work is shortened. Can be further improved. The locking piece 213 may not be continuously provided over the entire length of the main portion 210 in the longitudinal direction. For example, a plurality of locking pieces may be provided at intervals along the longitudinal direction of the main portion 210.

Further, the light source unit 2 faces the other end H2 of the substrate 200 in the lateral direction along the lateral direction of the substrate 200, and restricts the end H1 of the substrate 200 from moving in the direction of exiting the space. It has a regulatory department. Specifically, the regulating portion includes a wall-shaped positioning piece 212 protruding from the lower surface (opposing surface) of the main portion 210 of the support member 21. Further, the regulating portion includes a screw portion 560 of two fixing screws 56 for fixing the power supply case 51 to the main portion 210, and a screw portion 260 of two fixing screws 26 for fixing the two fixtures 23 to the main portion 210. including. That is, both the screw portion 560 of the fixing screw 56 and the screw portion 260 of the fixing screw 26 project from the lower surface (opposing surface) of the main portion 210 of the support member 21 (see FIGS. 9, 12, and 14).

Further, the substrate 200 has a plurality of recesses 202 recessed along the lateral direction of the substrate 200 (see FIG. 12). These plurality of recesses 202 are provided in one end H2 of the substrate 200. Then, the regulating portions (the screw portion 560 of the fixing screw 56 and the screw portion 260 of the fixing screw 26) are arranged one by one in the plurality of recesses 202 when viewed from the thickness direction (vertical direction) of the substrate 200 (FIG. See 12).

Thus, these restricting portions (including the positioning piece 212) can restrict the movement of the substrate 200 in the plane parallel to the facing surface of the main portion 210 with respect to the main portion 210. In particular, the threaded portion 560 of the fixing screw 56 and the threaded portion 260 of the fixing screw 26 are arranged in the recess 202 of the substrate 200, so that not only in the lateral direction of the main portion 210 but also in the longitudinal direction of the main portion 210. On the other hand, the movement of the substrate 200 can be restricted.

As described above, the light source unit 2 positions the substrate 200 with respect to the main portion 210 by the regulation portion (positioning piece 212, screw portion 560 of the fixing screw 56 and screw portion 260 of the fixing screw 26) of the main portion 210. Moreover, the movement of the substrate 200 can be restricted. As a result, the light source unit 2 can improve workability when fixing the substrate 200 to the main portion 210 with the fixing member (stepped screw 25).

By the way, in the light source unit 2, a part of the head 250 of the stepped screw 25 which is a fixing member overlaps with the tip of the positioning piece 212 when viewed from the thickness direction (vertical direction) of the substrate 200 (FIG. 12 and FIG. See FIG. 13). That is, the stepped screw 25 can be tightened only to the position where the head 250 of the stepped screw 25 comes into contact with the tip of the positioning piece 212 of the main portion 210.

Therefore, the light source unit 2 can prevent the stepped screw 25 from being excessively tightened by bringing the head 250 of the stepped screw 25 into contact with the tip of the positioning piece 212. If the head 250 of the stepped screw 25 does not come into contact with the tip of the positioning piece 212, the substrate 200 may be warped or distorted if the stepped screw 25 is excessively tightened. It is preferable that the head 250 does not protrude outside the positioning piece 212 so as not to come into contact with the mounting portion 222 of the cover 22 (see FIG. 14).

Here, since the cylindrical portion 252 of the stepped screw 25 is thicker than the screw hole of the main portion 210 into which the threaded portion 251 of the stepped screw 25 is tightened, the cylindrical portion 252 is stepped at a position where the cylindrical portion 252 hits the facing surface of the main portion 210. Tightening of the screw 25 is restricted (see FIG. 13). Therefore, if the height of the cylindrical portion 252 of the stepped screw 25 is higher than the height from the lower surface of the main portion 210 to the tip of the positioning piece 212, the head 250 of the stepped screw 25 contacts the tip of the positioning piece 212. It is possible to prevent the stepped screw 25 from being excessively tightened without causing the stepped screw 25 to be excessively tightened.

(4) Modifications of the Embodiment Some modifications of the light source unit 2 according to the embodiment will be described.
