Description

  Embodiments of the present invention relate to a lighting apparatus such as a projector that is installed outdoors and illuminates the upper side.

  A lamp is provided inside the substantially bullet-shaped reflector, and a light-projecting plate made of a glass plate or the like that closes the light-projecting opening of the support frame is attached to a ring-shaped support frame attached to the light-projecting side opening of the reflector. Conventionally, a projector that can be attached via a packing and that supports a support frame over both ends of an attachment portion formed in a U-shape so that the support frame can be oriented in an arbitrary direction is known.

  In this projector, the peripheral portion of the light projecting plate is continuously bordered by the support frame over the entire periphery, so that a concave portion is formed by the light projecting plate and the support frame.

  Floodlights installed outdoors are exposed to rainwater. Therefore, when this projector is used with the projector plate facing upward, the recess formed by the projector plate and the support frame receives rainwater, etc., but this rainwater is blocked by the ring-shaped support frame to the outside. It will not be discharged.

  In such a configuration in which rainwater or the like stays in the concave portion, when the packing is deteriorated and the waterproof performance is lowered, there is a possibility that the water floods into the projector. Further, as the water accumulated in the recesses is dried, the surface of the light projecting plate is soiled and the brightness is reduced due to the soiling.

  Such a problem can be solved by fixing the light projecting plate to the support frame with putty or caulking material so that the surface of the support frame and the surface of the light projecting plate are continuous at the same height. However, most of the putty and caulking materials require a considerable time until they are cured to some extent and can securely hold the light projection plate, so that the productivity is lowered and the cost is increased. Also, putty and caulking materials that can be cured to some extent instantly and securely hold the projector plate are not only expensive, but often require special equipment. Since the handling is troublesome, the cost is still high.

  Therefore, it is preferable to fix the light projection plate without using putty or caulking in a lighting fixture such as a projector used outdoors with the light projection plate facing upward, in order to reduce the manufacturing cost. Consideration is required to prevent rainwater from accumulating on the floodlight.

Thereby, it deform | transforms so that the site | part between side walls may hang down with dead weight, and it is suppressed that it leaves | separates from a light projection panel, and it is possible to ensure the waterproofness by a waterproof ring.

  The lighting fixture of Embodiment 4 is characterized in that, in Embodiment 3, the side plate has a support convex portion that is inserted into the waterproof member and supports the ring support portion from below.

  In Embodiment 4, since the ring support portion is supported from the lower side by the support convex portion of the side plate that is harder than the waterproof member in Embodiment 3, the portion between the side walls of the waterproof ring and the ring support portion are referred to as the support convex portion. It is sandwiched between the light projecting panel pushed by the upper edge material, and the close contact between the light projecting panel and the ring support portion between the side walls of the waterproof ring is strengthened. Thereby, it is possible to make the waterproof property by a waterproof ring more reliable.

After that, according to further tightening of the connection screw, the contact point between the protrusion and the contact surface is used as a fulcrum, the connection screw is used as a power point, and the portion where the light emitting panel of the upper edge material is pressed is used as the action point. The upper edge member is screwed to the upper end of the connection. At this time, since a gap is provided between the upper edge member and the upper end of the connection except for the contact point between the protrusion and the contact surface, the screw is fixed by the screwing with the contact point between the protrusion and the contact surface as a fulcrum. With the moment applied to the rim material, it is possible to reliably press the light projection panel from above with the upper rim material and to ensure the waterproof property by the waterproof ring.

  Hereinafter, the lighting fixture of Example 1 is demonstrated in detail with reference to FIGS.

  1 to 3 and 8, reference numeral 1 denotes a lighting fixture supported by a fixture holder (not shown). The fixture holder and the lighting fixture 1 constitute a lighting device. In FIG. 8, reference numeral 2 denotes a bolt holder, reference numeral 3 denotes a bolt, reference numeral 4 denotes a washer, and reference numeral 5 denotes a nut, which constitute a connecting means for connecting the fixture holder and the lighting fixture 1. ing. The bolt holder 2 is used to fit the head of the bolt 3 and prevent the bolt 3 from rotating.

  The luminaire 1 is installed together with a fixture holder outdoors in order to emit light upward and illuminate an irradiation target, for example, a wall surface of a building. The luminaire 1 includes a main body 11, a waterproof ring 25, a light projecting panel 28, two upper edge members 31, a light source unit 41, two waterproof members 61, two side plates 71, and the like. is doing.

  As shown in FIGS. 1, 4, and 9, the main body 11 is obtained by cutting a metal mold material, for example, an aluminum alloy extruded mold material, to a predetermined length, and is, for example, long. As shown in FIG. 8, the main body 11 has a bottom wall 13 integrally and continuously formed at the lower end of the side wall 12 facing the width direction (short direction) perpendicular to the longitudinal direction. Thereby, both ends in the longitudinal direction of the main body 11 are opened, and the space between the side walls 12 is also opened upward.

  A groove 14 for accommodating the bolt holder 2 of the connecting means is formed on one side wall 12. A groove partition wall portion 14a that partitions this groove 14 and forms a part of the outer surface of one side wall 12 is sandwiched between the bolt holder 2 and the washer 4 as the nut 5 is tightened. One side wall 12 is attached to a predetermined position in the longitudinal direction.

  As shown in FIG. 8 and the like, the opposing side walls 12 each have a connection upper end portion 16, and these connection upper end portions 16 oppose each other in the width direction of the main body 11 and are parallel to each other. As shown in FIGS. 8, 10, and 11, the coupling upper end portion 16 is provided with a seal groove 17, a screw hole 18, and a protrusion 19. The seal groove 17 and the protrusion 19 extend over the entire length in the longitudinal direction of the connection upper end portion 16. A plurality of screw holes 18 are provided at intervals in the longitudinal direction of the connection upper end portion 16, but only one is shown in the drawing.

  The seal groove 17 is partitioned by a pair of long and short groove walls 17a and 17b whose width is upward, and is open upward. The shorter groove wall 17b faces the upper surface opening of the main body 11 and partitions the opening. The longer groove wall 17 a is provided away from the groove wall 17 b corresponding to the groove width of the seal groove 17. The screw hole 18 is provided at a position displaced from the seal groove 17 along the width direction of the connection upper end portion 16. The protrusion 19 is provided on the side opposite to the seal groove 17 with the screw hole 18 as a boundary, and protrudes upward. The protrusion 19 has an upward contact surface 19 a (see FIG. 10). In the first embodiment, the contact surface 19 a is formed on the horizontal upper end surface of the protrusion 19.

  A hollow portion 20 that is continuous with the back side (lower side) of the connection upper end portion 16 and extends over the entire length in the longitudinal direction of the side wall 12 is integrally formed with each of the side walls 12. A screw hole 18 is opened in the hollow portion 20. On the inner surface of the substantially central portion of the side wall 12 in the height direction, a support protrusion 21 extending integrally over the entire length of the side wall 12 is integrally formed.

  Further, an upper self-tapping hole 22 is formed in the side wall 12 so as to face the hollow portion 20. At the same time, lower self-tapping holes 23 are formed at corners where the side wall 12 and the bottom wall 13 are continuous. The openings of the lower self-tapping holes 23 are opened on the lower surface of the main body 11.

  The waterproof ring 25 is formed in a square shape corresponding to the size of the main body 11, for example, a long square ring shape, by a material that can be elastically deformed such as synthetic rubber. The longer portion 25a (see FIGS. 4 and 5) of the waterproof ring 25 is fitted in the seal groove 17 and supported by the connecting upper end portion 16, and the portion between the side walls which is the shorter portion 25b of the waterproof ring 25. (See FIG. 4 and FIG. 5) is disposed across the parallel connecting upper end 16. As shown in FIGS. 10 and 11, the cross-sectional shape of each part in the free state of the waterproof ring 25 is circular, and its diameter is larger than the height of the short groove wall 17b and smaller than the height of the long groove wall 17a.

  The light projecting panel 28 is made of a translucent material such as a glass plate, and has a square shape that is slightly larger than the waterproof ring 25, such as a long rectangle. The light projecting panel 28 is disposed over the parallel connecting upper end portions 16 with the edge portion along the longitudinal direction positioned above the seal groove 17. Thereby, the light projection panel 28 is supported by the waterproof ring 25 in contact with the peripheral portion from below. The longer edge of the light projecting panel 28 is brought close to the longer groove wall 17a of the seal groove 17, whereby the light projecting panel 28 is positioned in the width direction of the main body 11 using the groove wall 17a as a stopper. ing.

  The two straight upper edge members 31 are obtained by cutting a metal mold, for example, an aluminum alloy extrusion mold, into the same length as the main body 11. As shown in FIGS. 4 and 8 to 11, each upper edge member 31 has a presser edge 32, a self-tapping hole 33, a plurality of screw through holes 34, and a contact portion 35.

  The presser edge 32 is formed so as to protrude integrally from the upper end portion of the upper edge member 31 to the side. A cushioning material 36 (see FIGS. 8, 10, and 11) made of rubber, elastomer, or the like is attached to the lower surface of the presser edge 32 and a corner continuous to the base thereof. The self-tapping hole 33 is provided through the upper edge member 31 in the longitudinal direction at a position spaced a predetermined distance from the presser edge 32 in the width direction of the upper edge member 31. In order to reduce the material cost of the upper edge member 31 and reduce the weight, a hole 33a (see FIG. 10) that is parallel to the self-tapping hole 33 and continues to the lower side is provided in the upper edge member 31. However, this may be omitted.

  The screw through holes 34 are provided at intervals in the longitudinal direction of the upper edge member 31. These screw through holes 34 are perpendicular to the self-tapping holes 33 and penetrate the upper edge member 31 in the vertical direction.

  The contact portion 35 is provided on the opposite side of the presser edge 32 with the self-tapping hole 33 as a boundary, and extends over the entire length of the upper edge member 31 in the longitudinal direction. The contact portion 35 is formed in accordance with the shape of the protrusion 19, and has a contact surface 35 a (see FIG. 10) that contacts the contact surface 19 a of the protrusion 19. The contact surface 35a is formed as a horizontal surface, for example.

  The upper edge member 31 is inserted into each screw through hole 34 from above and is connected to the upper end portion of the connecting screw 37 (see FIGS. 8, 10, and 11) screwed into the screw holes 18 of the connecting upper end portion 16. 16 are connected to each other. The presser edge 32 of the upper edge member 31 covers the longer edge of the light projecting panel 28 from above. At the same time, the contact portion 35 is in contact with the protrusion 19 of the connection upper end portion 16 from above.

  A panel fixing structure is formed by fixing the upper edge member 31. That is, the longer edge portion of the light projecting panel 28 is sandwiched between the waterproof ring 25 and the presser edge 32 of the upper edge member 31 from above and below to ensure the waterproofness therebetween. Specifically, along with the screwing, the longer edge of the light projecting panel 28 is pressed downward through the buffer material 36 and elastically deformed so that the waterproof ring 25 is compressed. 25 is in close contact with the surface forming the seal groove 17 and in close contact with the lower surface of the longer edge of the light projecting panel 28.

  It should be noted that the metal presser edge 32 does not directly contact the longer edge of the glass floodlight panel 28 due to the buffering action of the buffer material 36 in the screwing or the like. For this reason, it is possible to prevent an excessive stress from acting on the light projecting panel 28 and prevent the light projecting panel 28 from being damaged.

  Since the two upper edge members 31 cover the parallel edge portions of the light projecting panel 28 and are screwed to the connecting upper end portion 16 as described above, the light is projected as shown in FIG. A groove 38 with the panel 28 as the bottom is formed. The groove 38 extends over the entire length of the main body 11 in the longitudinal direction.

  Further, in a state where the upper edge material 31 is connected to the connection upper end portion 16, the gap g () is removed between the upper edge material 31 and the connection upper end portion 16 except for the contact portion between the protrusion 19 and the contact portion 35. 8) is formed.

  By providing the gap g and the contact portion, the upper edge member 31 can surely press the edge of the light projection panel 28 from above as it is screwed to the connection upper end 16. is there.

  That is, the upper edge member 31 is screwed to the connection upper end portion 16 in a state where the presser edge 32 of the upper edge member 31 is caught from the upper side by the longer edge portion of the light projecting panel 28. The connection screw 37 is passed through the through hole 34 from above, and the connection screw 37 is screwed into the screw hole 18 of the connection upper end portion 16.

  In this case, the position of the screw hole 34 is shifted in the width direction of the upper edge member 31 with respect to the presser edge 32 in contact with the light projecting panel 28 via the buffer material 36, and the connection upper end 16 and the upper edge There is a gap between the material 31 and the connecting screw 37 to allow tightening.

  Therefore, assuming that the protrusion 19 and the contact portion 35 do not exist, as the connecting screw 37 is screwed, the upper edge member 31 is inclined with the upper line of the longer edge of the light projecting panel 28 as a fulcrum, The tip end side of the presser edge 32 is further away from the upper surface of the light projecting panel 28. As a result, the long edge of the light projecting panel 28 cannot be sufficiently pressed from directly above the waterproof ring 25. As a result, the tightness between the waterproof ring 25 and the light projecting panel 28 becomes weak, and the waterproof performance of the waterproof ring 25 may be reduced.

  However, such a problem can be solved by providing the projection 19 on the connection upper end portion 16 and providing the upper edge member 31 with the contact portion 35 in contact with the projection 19 from above.

  That is, in the initial stage of screwing the upper edge material 31, the upper edge material 31 is in a state where the holding edge 32 of the upper edge material 31 is hooked from above on the longer edge of the light projecting panel 28 as described above. A connecting screw 37 is passed through the screw through hole 34 from above, and the connecting screw 37 is screwed into the screw hole 18 of the connecting upper end portion 16. In this case, there is a gap between the connection upper end portion 16 and the upper edge member 31 so that the connection screw 37 can be tightened (see FIG. 11). This gap is narrower than the other gap g1 between the connection upper end portion 16 and the upper edge member 31.

  When the screwing of the connecting screw 37 proceeds from this state, first, the contact portion 35 comes into contact with the protrusion 19 from above, and the upper edge member 31 is supported by the protrusion 19 from the lower side. The contact portion 35 side portion of the head does not drop as the screwing progresses. The position of the screw hole 34 is shifted in the width direction of the upper edge member 31 with respect to the presser edge 32 that is in contact with the light projecting panel 28 via the buffer material 36, and the screw hole 34 is used as a boundary. The protrusion 19 and the contact portion 35 are located on the side opposite to the presser edge 32.

  For this reason, as the connection screw 37 is further screwed in, the contact portion between the projection 19 and the contact portion 35 is used as a fulcrum, the connection screw 37 is used as a power point, and the longer portion 25a of the waterproof ring 25 is used. The upper edge member 31 is screwed to the connection upper end portion 16 with the portion where the presser edge 32 pressed the light projecting panel 28 just above the working point. In this case, a gap g (see FIG. 8) is provided between the upper edge member 31 and the connection upper end portion 16 except for the contact portion between the contact portion 35 of the upper edge member 31 and the protrusion 19. Along with the screwing, a moment for moving the presser edge 32 downward is applied to the upper edge member 31 with the contact point between the protrusion 19 and the contact portion 35 as a fulcrum. Therefore, the upper edge member 31 can reliably hold the edge of the light projecting panel 28 from right above the long-direction portion 25a of the waterproof ring 25. Since it is strengthened, it is possible to ensure the waterproofness by the waterproof ring 25.

  In the first embodiment, the protrusion 19 is provided on the connection upper end 16. Instead, the protrusion 19 protruding downward is provided on the upper edge member 31, and the contact surface with which the tip of the protrusion 19 contacts is connected. It can also be provided at the upper end 16. In this case, the contact surface of the connection upper end portion 16 may be formed by the bottom surface of the recessed portion corresponding to the protrusion 19 or the upper end of the screw hole 18 of the connection upper end portion 16 without forming the recessed portion. It is also possible to form a flat surface that is the same height as the open surface and is continuous.

  As shown in FIG. 8, the light source unit 41 includes a unit base 42, for example, a plurality of light emitting modules 44 (only one is shown), the same number of lenses 49 as the light emitting modules 44, and the same number of light distribution control members as the light emitting modules 44. Specifically, a louver 52 and a power supply unit 55 are provided.

  The unit base 42 is obtained by cutting a metal mold material, such as an aluminum alloy extrusion mold material, into a length slightly shorter than the main body 11. The unit base 42 has engaging grooves 42 a that open on both side surfaces in the width direction and groove portions 42 b that open upward. These extend over the entire length of the unit base 42 in the longitudinal direction.

  The light emitting module 44 is formed, for example, by mounting a plurality of light emitting portions 46 (only one is shown) and a pair of electric wire connectors 47 (only one is shown) on a rectangular module substrate 45. The total length of the module substrate 45 is shorter than the total length of the unit base 42.

  Next, in this state, the waterproof ring 25 is fitted into the seal groove 17 and the ring fitting groove 65 from above. Therefore, the waterproof member 61 is used to support the ring so that the shorter portion 25b of the waterproof ring 25 does not hang down even though the shorter portion 25b of the waterproof ring 25 extends over the parallel connecting upper end 16 of the main body 11. The portion 66 can be supported from below.

  Thereafter, the light projecting panel 28 is arranged so that the peripheral portion thereof is placed on the waterproof ring 25. In this case, the width direction position of the light projection panel 28 with respect to the main body 11 is regulated by the groove wall 17a, and the longitudinal direction position of the light projection panel 28 with respect to the main body 11 is regulated by the upper portion of the waterproof member 61.

  Next, the upper edge material 31 is screwed to the connection upper end portion 16 of the main body 11 by the procedure described above. Accordingly, the waterproof ring 25 is compressed from above via the light projecting panel 28, and the waterproof ring 25 and the lower surface of the peripheral portion of the light projecting panel 28 are brought into close contact with each other. At the same time, the peripheral surface of the longer portion 25 a of the waterproof ring 25 that is elastically deformed is brought into close contact with the surface of the seal groove 17, and the peripheral surface of the shorter portion 25 b of the waterproof ring 25 is the surface of the ring fitting groove 65. Be in close contact with.

  In this case, since the ring support portion 66 having the ring fitting groove 65 is supported from the lower side by the support convex portion 77 which is harder than this, the elastic deformation of the shorter portion 25b is reliably performed. Therefore, it is possible to securely contact the lower surface of the light projecting panel 28 and the surface of the ring fitting groove 65. Due to the close contact, waterproofing between the waterproof ring 25 and the light projecting panel 28 is secured, and waterproofing between the waterproof ring 25 and the seal groove 17 and the ring fitting groove 65 is secured. That is, it is possible to ensure waterproofing around the waterproof ring.

  Finally, the screws 72 and 73 are tightened to fix the side plate 71 to the end of the main body 11 with the waterproof member 61 sandwiched between the end surface of the main body 11 and the screw 74 is screwed into the self-tapping hole 33. Thus, the side plate 71 is fixed to the end portion of the upper edge member 31 with the waterproof member 61 sandwiched between the end surface of the upper edge member 31. With the waterproof member 61 elastically deformed accordingly, waterproofing between the waterproof member 61 and the side plate 71 as well as waterproofing between this and the end surface of the main body 11, the end surface of the light projecting panel 28, and the end surface of the upper edge member 31 are provided.

  Further, as shown in FIG. 5, the waterproof member 61 comes into contact with the longitudinal end surface of the unit base 42 as shown in FIG. 5, so that the light source unit 41 does not move inadvertently along the support protrusions 21. Further, the light source unit 41 can be positioned in the longitudinal direction of the main body 11.

  In addition, when the ring support portion 66 without the ring fitting groove 65, that is, the ring support portion 66 having a configuration in which the portion in contact with the inner periphery of the waterproof ring 25 is omitted in FIG. Regardless of the procedure, it is also possible to assemble the lighting fixture 1 by the following procedure.

  First, after setting the waterproof ring 25 over the seal groove 17 of the parallel connecting upper end portion 16 of the main body 11 and placing the light projecting panel 28 thereon, the upper portion 16 is connected to each of the connecting upper end portions 16 according to the procedure described above. The edge member 31 is screwed. Next, the waterproof member 61 is disposed so as to cover the end face of the main body 11, the end face of the light projecting panel 28, and the end face of the upper edge member 31. In this case, the ring support portion 66 of the waterproof member 61 is positioned below the shorter portion 25b of the waterproof ring 25 across the parallel seal grooves 17, and the waterproof member 61 is disposed at an appropriate position. Move upwards as is done. Thereby, the shorter part 25b can be supported by the ring support part 66 from the lower side. Thereafter, the side plate 71 is overlaid on the waterproof member 61, and the side plate 71 is screwed to the ends of the main body 11 and the upper edge member 31 using screws 72 to 74. The assembly of the lighting fixture 1 is completed by the above procedure.

  The luminaire 1 having the above-described configuration is installed outdoors as a floodlight in a substantially horizontal state with the floodlight panel 28 facing upward in order to illuminate the wall surface of a building. When the light emitting unit 46 of the light source unit 41 included in the lighting fixture 1 emits light, upward illumination light emitted from the light emitting unit 1 first enters the lens 49, and the projection angle is set by the lens 49 in the width direction of the main body 11. And is emitted from the upper surface (light emitting surface) of the lens 49. The emitted light passes upward through the light projecting panel 28 that is directly above the lens 49. Thereby, wall surface illumination is performed.

  The heat generated by the LED chip included in the light emitting unit 46 during the lighting is conducted to the metal unit base 42 through the module substrate 45, and further conducted from the unit base 42 to the metal main body 11.

Since water is collected and discharged in this way, it is possible to smoothly drain water from the member recess 62 to the side plate recess 76.

  Further, the bottom surface 76 a of the side plate recess 76 is inclined so as to gradually become lower than the top surface of the light projection panel 28 and the bottom surface 62 a of the member recess 62 as it is farther from the end surface of the light projection panel 28 and the waterproof member 61. For this reason, the water discharged from the member recess 62 to the side plate recess 76 can be smoothly guided and discharged by the inclination of the bottom surface 76 a of the side plate recess 76.

  Such drainage can prevent water from staying in the groove 38, so that even when the waterproof ring 25 is deteriorated and its waterproof performance is lowered, it is possible to prevent water from entering the main body 11 from around the floodlight panel 28. is there. Further, as in the case where water accumulates in the groove 38, it is possible to suppress the dirt on the surface of the light projection panel 28 and the decrease in brightness caused by the dirt as the water dries. . In addition, due to the smooth drainage as described above, it is difficult for water to remain in the member recess 62 and the side plate recess 76, so that the end surface of the main body 11 and the end surface of the light projecting panel 28 and the contact portion of the waterproof member 61 are submerged.
