In the embodiment of the present invention, the X axis, the Y axis, and the Z axis are orthogonal to each other, the X axis and the Y axis are parallel to the horizontal plane, and the Z axis is parallel to the vertical line.

  FIG. 1 is a perspective view showing a front side of a lighting fixture 1 according to an embodiment of the present invention. The front of the luminaire 1 is the side from which the luminaire 1 emits light. The luminaire 1 includes a first reflection member 5 (reflection member) that reflects light, a pair of flat plate-like diffusion members 7 that diffuse light, a pair of plate-like second reflection members 9 that reflect light, and a groove portion 15. A pair of plate-like first reinforcing members 11 (reinforcing members), a pair of plate-like second reinforcing members 13, a plurality of screws 17, a plurality of screws 19, and a pair of light sources that emit light. The unit 23 is provided.

  The first reflecting member 5 reflects the light emitted from the light source unit 23 and diffused by the diffusing member 7. The first reflecting member 5 extends along the longitudinal direction of the mounted member 10 and is disposed at a position covering the groove portion 15 of the mounted member 10. The longitudinal direction of the mounted member 10 is substantially parallel to the X axis. The cross section of the first reflecting member 5 is substantially V-shaped (including V-shaped). Therefore, the irradiation angle of the light emitted from the light source unit 23 can be changed by changing the substantially V-shaped angle. Further, since the first reflecting member 5 has a substantially V-shaped cross section, the first reflecting member 5 can have a larger volume than a flat plate-shaped reflecting member, so that the amount of heat storage can be increased and high heat dissipation can be ensured. it can.

  The first reflecting member 5 has two light reflecting surfaces because the cross section is substantially V-shaped. One of the two light reflecting surfaces is adjacent to the one diffusing member 7 and is inclined with respect to the light emitting surface of the one diffusing member 7. Of the two light reflecting surfaces, the other light reflecting surface is adjacent to the other diffusing member 7 and is inclined with respect to the light emitting surface of the other diffusing member 7. The angle formed by one light reflecting surface and one light emitting surface is substantially the same as the angle formed by the other light reflecting surface and the other light emitting surface.

  The first reflecting member 5 protrudes downward in the Z-axis direction with respect to the light emitting surface of the diffusing member 7. The first reflecting member 5 has a substantially V-shaped cross section so that its surface area is larger than that of a flat plate-shaped reflecting member, and the first reflecting member 5 protrudes downward from the light emitting surface of the diffusing member 7 in the Z-axis direction. Since the exposure amount to the front side of the luminaire 1 can be increased, high heat dissipation can be ensured.

  In order to efficiently reflect the light emitted from the light source unit 23, at least the light reflecting surface of the first reflecting member 5 is preferably subjected to a reflection process such as white coating. The first reflecting member 5 is preferably formed of a material having high heat conductivity in consideration of the heat dissipation of the lighting fixture 1, and is preferably formed of, for example, metal. Among metals, it is preferable that the metal is formed of, for example, aluminum or an aluminum alloy in consideration of ease of forming process and weight reduction of the lighting fixture 1.

  The pair of diffusing members 7 are disposed at positions adjacent to the pair of long sides of the first reflecting member 5. The pair of diffusing members 7 are arranged such that the light exit surfaces are located on the same plane. The diffusing member 7 is disposed along the longitudinal direction of the attached member 10 at a position covering the light source unit 23. The pair of diffusing members 7 has substantially the same shape and size of the light exit surface. The diffusing member 7 diffuses the light emitted from the light source unit 23. The diffusion member 7 is formed, for example, by molding a resin mixed with a light diffusion material into a plate shape. The diffusing member 7 is formed, for example, by providing minute irregularities on the light emitting surface or light incident surface of a transparent plate member.

  One second reflecting member 9 of the pair of second reflecting members 9 is disposed at a position adjacent to the long side of one diffusing member 7 of the pair of diffusing members 7, and the other second reflecting member 9 is disposed on the other side.

The second reflecting member 9 has a light reflecting surface, protrudes downward from the edge of the diffusing member 7, and the light reflecting surface is inclined with respect to the light emitting surface of the diffusing member 7. The pair of second reflecting members 9 are inclined in directions opposite to each other, and the inclination angles of the light reflecting surfaces with respect to the light emitting surface of the diffusing member 7 are substantially the same.

  The edge of the diffusing member 7 is along the longitudinal direction of the mounted member 10. The second reflecting member 9 reflects the light emitted from the light source unit 23 and diffused by the diffusing member 7. In order for the second reflecting member 9 to efficiently reflect the light emitted from the light source unit 23, at least the light reflecting surface is preferably subjected to a reflection process such as white coating. The second reflecting member 9 is preferably made of a material having high heat conductivity in consideration of the heat dissipation of the lighting fixture 1, for example, preferably made of metal. Among metals, it is preferable that the metal is formed of, for example, aluminum or an aluminum alloy in consideration of ease of forming process and weight reduction of the lighting fixture 1.

The mounted member 10 is disposed on the center line CL of the lighting fixture 1 and is formed to extend in one direction. In the present embodiment, the mounted member 10 is formed so as to extend along the X axis. Both ends in the longitudinal direction of the mounted member 10 are open. The mounted member 10 has a groove 15 extending along the longitudinal direction of the mounted member 10. The cross section of the mounted member 10 is U-shaped.

  Since the mounted member 10 has a U-shaped cross section, the volume of the mounted member 10 can be increased compared to a flat plate-shaped mounted member, so that the amount of stored heat can be increased and high heat dissipation can be ensured. Since the surface of the mounted member 10 is larger than that of a flat plate-shaped mounted member due to the U-shaped cross section, high heat dissipation can be secured. The mounted member 10 is preferably formed of a material having high heat conductivity in consideration of the heat dissipation of the lighting fixture 1, and is preferably formed of, for example, metal. Among metals, it is preferable that the metal is formed of, for example, aluminum or an aluminum alloy in consideration of ease of forming process and weight reduction of the lighting fixture 1. In addition, the cross section of the to-be-attached member 10 is not limited to U shape, and can take arbitrary shapes.

  The mounted member 10 includes a mounted portion 15a, a side wall portion 15b, and a side wall portion 15c. The attached portion 15 a, the side wall portion 15 b, and the side wall portion 15 c extend along the longitudinal direction of the attached member 10 and form a groove portion 15. A circular hole 3a and a dharma hole 3b are formed in the attached portion 15a. The hole 3a penetrates the attached portion 15a and is located at the approximate center of the attached portion 15a. The dharma hole 3 b penetrates the attached portion 15 a and is located between the hole 3 a and one end in the longitudinal direction of the attached member 10. A through hole 3g is formed in the side wall portion 15b.

The bolt 45a is inserted into the dharma hole 3b (FIG. 2) of the mounted member 10. And the nut 45b is couple | bonded with the volt | bolt 45a from the inside of the groove part 15. FIG. As a result, the mounted member 10 is mounted at the mounting position of the building, and the lighting fixture 1 is suspended from the mounting member 45. In this embodiment, the to-be-attached member 10 is attached to the attachment position of a building so that the lighting fixture 1 may be arrange | positioned in the attachment hole RH formed in board RB as a ceiling of a building.

  FIG. 4 is a perspective view showing the lighting fixture 1 with the first reflecting member 5 and the diffusing member 7 removed. A through hole 3c and a through portion 3d are formed in the side wall portion 15c of the attached member 10. The groove portion 15 has a pair of edge portions 15d. The edge portion 15 d is along the longitudinal direction of the mounted member 10. The edge 15d is bent. In the present embodiment, the edge 15d is hemmed (bent over 180 degrees). Therefore, the diffusion member 7 (FIG. 1) can be prevented from being damaged by the contact of the edge 15d, and the rigidity and strength of the mounted member 10 can be improved. The edge portion 15 d is along the longitudinal direction of the mounted member 10. The edge 15d is not limited to the hemming process, and may be a bending process that can suppress at least damaging the diffusion member 7.

  Furthermore, with reference to FIG. 4, the other component of the lighting fixture 1 is demonstrated. The luminaire 1 further includes a pair of light source holding members 24, four support members 27, a terminal block 29, and a plurality of screws 30 in addition to the pair of light source units 23.

  Each of the light source units 23 includes a plurality of light emitting elements 23a that emit light and a rectangular and flat substrate 23b. In the present embodiment, the light emitting element 23a is an LED. A plurality of light emitting elements 23a are mounted on each mounting surface of the substrate 23b. The plurality of light emitting elements 23a are arranged in two rows along the longitudinal direction of the attached member 10 on each substrate 23b. In addition, the number of arrangement of the light emitting elements 23a is an example.

  Each of the light source holding members 24 holds the light source unit 23. Each of the light source holding members 24 has a plate shape, and has a main surface 22A for holding the light source unit 23 and a surface 22B (FIG. 2) opposite to the main surface 22A. The main surface 22A has a substantially horizontal mounting surface 24a, an inclined surface 24b, and an inclined surface 24c. The surface opposite to the mounting surface of the substrate 23b is in contact with the mounting surface 24a or is opposed to the mounting surface 24a with a minute gap or a heat dissipation material interposed therebetween. Thereby, the heat generated by the light source unit 23 is transmitted to the light source holding member 24, and an abnormal temperature rise of the light source unit 23 can be suppressed.

  In order to efficiently reflect the light emitted from the light source unit 23, at least the main surface 22A of the light source holding member 24 is preferably subjected to a reflection process such as white coating. The light source holding member 24 is preferably formed of a material having high heat conductivity in consideration of heat dissipation of the light source unit 23, and is preferably formed of, for example, metal. Among metals, it is preferable that the metal is formed of, for example, aluminum or an aluminum alloy in consideration of ease of forming process and weight reduction of the lighting fixture 1.

  The substrate 23b of the light source unit 23 is attached to the attachment surface 24a by a plurality of screws 25. That is, the substrate 23 b is attached to the light source holding member 24. Since the lighting fixture 1 which concerns on this embodiment is not providing the case which accommodates the light emitting element 23a and the board | substrate 23b, it can reduce a number of parts. As a result, the cost can be reduced and the number of assembling steps of the lighting fixture 1 can be reduced. In addition, the heat dissipation effect of the light source unit 23 can be improved.

  The inclined surface 24b and the inclined surface 24c are formed at positions adjacent to the mounting surface 24a in the Y-axis direction and sandwiching the mounting surface 24a. The inclined surface 24b protrudes downward from one of both edges of the mounting surface 24a and is inclined with respect to the mounting surface 24a. The inclined surface 24c protrudes downward from the other of the edges of the attachment surface 24a and is inclined with respect to the attachment surface 24a. Both edges of the mounting surface 24 a are along the longitudinal direction of the mounted member 10. The inclined surface 24b and the inclined surface 24c reflect light emitted from the light emitting element 23a. A through hole 3f is formed in the inclined surface 24c of the light source holding member 24 that contacts the side wall portion 15b. A through hole 3e is formed in the inclined surface 24c of the light source holding member 24 that contacts the side wall portion 15c.

  The light source holding member 24 will be described with reference to FIG. FIG. 5 is an exploded perspective view showing the back side of the luminaire 1. The pair of light source holding members 24 is arranged at a position sandwiching the attached member 10. The light source holding member 24 is engaged with the mounted member 10 along the longitudinal direction of the mounted member 10. That is, the luminaire 1 is configured by engaging the light source holding member 24 with the attached member 10, and the light source holding member 24 and the attached member 10 are separate members. Further, the light source holding member 24 and the mounted member 10 are engaged with each other with a margin so that slight displacement is possible.

  Therefore, even if the attached member 10 is deformed due to its own weight, the influence on the light source holding member 24 is compared with the case where the light source holding member and the attached member are integrally formed. Small. That is, since the light source holding member 24 and the attached member 10 are configured as separate members, even if the attached member 10 is deformed, energy due to the deformation is hardly transmitted to the light source holding member 24. As a result, the light source holding member 24 can be prevented from being distorted by the deformation of the attached member 10. In addition, since the light source holding member 24 is engaged along the longitudinal direction of the attached member 10, the light source holding member 24 and the attached member are compared with the case where the light source holding member is superimposed on the lower surface of the attached member. There are few contact parts with the member 10. FIG. Therefore, even if the attached member 10 is deformed, the light source holding member 24 can be further prevented from being distorted.

  According to the present embodiment, since the light source holding member 24 can be prevented from being distorted, the light source unit 23 can be prevented from floating or peeling off from the light source holding member 24.

The hook part 73 is hooked on the upper edge of the contact part 71. The same applies to the other second reflecting member 9 and the other light source holding member 24.

  Then, one second reinforcing member 13 is brought into contact with one end portion of one first reinforcing member 11 and each second reflecting member 9. Further, the screw 19 passes through the second reinforcing member 13 and is screwed into the first reinforcing member 11, and the screw 19 passes through the second reinforcing member 13 and is screwed into the contact portion 74 of the second reflecting member 9. . As a result, one second reinforcing member 13 is fixed to one end portion of one first reinforcing member 11 and each second reflecting member 9. Similarly, the other second reinforcing member 13 is fixed to the other first reinforcing member 11 and the other end of each second reflecting member 9. The pair of second reflecting members 9 are reinforced by the pair of second reinforcing members 13. As a result, the rigidity and strength of the lighting fixture 1 are further improved.

  As described above with reference to FIGS. 1 to 6, according to the present embodiment, the luminaire 1 is configured by the light source holding member 24 being engaged with the mounted member 10, and the light source holding member 24 and the attached member 10 are separate members. Therefore, even if the attached member 10 is deformed, the light source holding member 24 can be prevented from being distorted.

  As shown in FIG. 2, according to the present embodiment, the opposite surface 22B of the light source holding member 24 is exposed. That is, the back side of the luminaire 1 is not covered with a case or the like. Therefore, it is possible to reduce the cost of the lighting fixture 1, reduce the weight of the lighting fixture 1, reduce the number of assembling steps of the lighting fixture 1, and improve the heat dissipation effect of the lighting fixture 1. In particular, the heat dissipation effect of the light emitting element 23a (FIG. 4) can be improved.

That is, the mounted member 10 protrudes toward the bolt 45a side from the opposite surface 22B. Therefore, when attaching the lighting fixture 1 to a building, the installation operator can easily grasp the position of the dharma hole 3b (FIG. 2), and the bolt 45a can be easily inserted into the dharma hole 3b.

  Furthermore, as shown in FIG. 5, according to the present embodiment, the support member 27 is sandwiched between the light source holding member 24 and the mounted member 10 and is held so as not to drop off. Therefore, a dedicated member and structure for holding the support member 27 so as not to drop off are unnecessary. As a result, when the cost of the lighting fixture 1 can be reduced, the assembly can be simplified.

  The power supply unit 41 of the lighting fixture 1 will be described with reference to FIGS. 2, 3, and 7. As shown in FIG. 2, the luminaire 1 further includes a power supply unit 41 that supplies power to the light source unit 23, a plurality of fixing members 43, and a plurality of screws 44. The power supply unit 41 is fixed to the mounted member 10 by a plurality of screws 44.

As a result, the back surface of the substrate 41c faces the inner upper surface of the case 41a, and the power supply circuit 41b faces downward.

  In the fourth procedure, the lid 60 is bent about 90 degrees along the perforation 59, and the case 41a has a rectangular parallelepiped shape (see arrow A2). As a result, the power supply circuit 41b and the substrate 41c are enclosed in the case 41a. In FIG. 7, the folded lid portion 60 is indicated by a two-dot chain line. One of the six surfaces of the case 41a where the lid 60 is bent is open. The opening of the case 41 a faces the outer surface of the side wall portion 15 c of the attached member 10. The power supply unit 41 was assembled by the first procedure to the fourth procedure.

  In the fifth procedure, the pair of claw portions 61 of the case 41a are engaged with a pair of engagement holes 63 formed in the side wall portion 15c of the attached member 10 (see arrow A3). The opening of the case 41a is closed by the outer surface of the side wall 15c. As a result, the power supply circuit 41b and the substrate 41c are surrounded by the outer surface of the side wall portion 15c and the inner surface of the case 41a.

  In the sixth procedure, the case 41a is fixed to the mounted member 10 by a plurality of screws 44 (FIG. 2). As a result, the power supply part 41 is disposed outside the attached member 10 along the side wall part 15 c of the attached member 10. The power supply unit 41 was attached to the attached member 10 by the fifth procedure and the sixth procedure.

  With reference to FIG. 4, the wiring connected to the power supply part 41 is demonstrated. A terminal block 29 is attached to the inner surface of the attached portion 15 a of the attached member 10. The terminal block 29 is located in the vicinity of the hole 3a. The cable 33 drawn from the hole 3 a is connected to the terminal block 29. The cable 31 connected to the terminal block 29 is inserted into the through-hole 3d, routed to the back side of the attached member 10, and then connected to the power source 41 (FIG. 2). Therefore, the external power supply voltage is supplied to the power supply unit 41 via the cable 33, the terminal block 29, and the cable 31. The through portion 3d clamps the cable 31. The power supply unit 41 generates an internal power supply voltage based on the external power supply voltage.

  The cable 37 extending from the power supply unit 41 is pulled out from the through hole 3 e and connected to one of the pair of light source units 23. Therefore, the internal power supply voltage is supplied from the power supply unit 41 to the light source unit 23. The cable 35 extending from the power supply unit 41 is pulled out from the through hole 3c, is pulled out from the through hole 3f through the through hole 3g (FIG. 2), and is connected to the other of the pair of light source units 23. Therefore, the internal power supply voltage is supplied from the power supply unit 41 to the light source unit 23.

In particular, the cable 31 and the cable 33 to which the external power supply voltage is supplied are likely to generate heat, but the heat generated by the cable 31 and the cable 33 arranged in the groove 15 is effective by improving the heat dissipation effect by the groove 15. Can diffuse. Further, due to the presence of the side wall portion 15 b and the side wall portion 15 c of the attached member 10, heat generated from the cable 31 and the cable 33 is accumulated and dissipated in the side wall portion 15 b and the side wall portion 15 c and is not easily transmitted to the light source unit 23. As a result, the temperature rise of the light source unit 23 can be suppressed. Furthermore, since the power supply part 41 is exposed to the outside of the attached member 10, it is possible to suppress heat generated by the power supply part 41 from entering the interior of the lighting fixture 1. As a result, the heat dissipation effect of the lighting fixture 1 can be further improved.

  Moreover, according to this embodiment, the both ends of the longitudinal direction of the to-be-attached member 10 are opening. Therefore, compared with the case where both ends are not open, the air circulation in the mounted member 10 is improved, the heat dissipation effect by the groove 15 can be further improved, and the heat dissipation effect of the lighting fixture 1 can be further improved. Moreover, the material of the to-be-attached member 10 decreases compared with the case where both ends are not open. As a result, the cost of the luminaire 1 can be reduced, and the luminaire 1 can be reduced in weight.

  Furthermore, according to this embodiment, since the power supply part 41 is arrange | positioned outside the to-be-attached member 10, compared with the case where a power supply part is arrange | positioned in the groove part of a to-be-attached member, the transversal direction of the to-be-attached member 10 The width of can be reduced. As a result, the rigidity and strength of the mounted member 10 can be improved, and consequently the rigidity and strength of the lighting fixture 1 can be improved.

  Furthermore, according to the present embodiment, the power supply circuit 41b and the substrate 41c are surrounded by the metal attached member 10 and the metal case 41a. Therefore, the material of the case 41a can be reduced as compared with the case where the power supply circuit and the substrate are surrounded only by the case. As a result, the cost of the lighting fixture 1 can be reduced, and the processing steps for the case 41a can be reduced.

  In the above, the effect regarding the power supply part 41 was demonstrated. As long as the power supply part 41 is arranged outside the attached member 10, even when the light source holding member and the attached member are integrally formed, the effect relating to the power supply part 41 can be achieved. Therefore, it is not required that the light source holding member and the attached member are separate members in order to achieve the effect relating to the power supply unit 41.
