[0001] SUMMARY OF THE DISCLOSURE The present invention relates to a lighting device. [Background technology]
[0002] 2. Description of the Related Art In a conventional lighting fixture to be installed on an installation surface such as a ceiling or wall, a light-transmitting cover that covers a light source attached to the fixture body is attached to the fixture body installed on the installation surface by means of a mounting screw.
[0003] Because the light-transmitting cover houses the fixture body in its opening and is attached to the fixture body by inserting mounting screws from the side of the light-transmitting cover, a gap may be formed between the periphery of the opening of the light-transmitting cover and the installation surface, in which case wind will enter the inside of the light-transmitting cover through the gap and push the light-transmitting cover from the inside, causing it to rattle and placing a load on the screw insertion points of the light-transmitting cover through which the mounting screws are inserted. Therefore, it is desirable to reduce the rattle of the light-transmitting cover in order to prevent load from being applied to the screw insertion points of the light-transmitting cover.

[0009] Hereinafter, one embodiment will be described with reference to FIGS.
[0010] The lighting device 10 is a long, moisture-proof and rain-proof lighting device that is installed on an installation surface 11 such as a ceiling surface or a wall surface. The lighting device 10 comprises a light source 12, an equipment body 13, a light-transmitting cover 14, and a covering body 15. In the lighting device 10, the light source 12 itself has a moisture-proof and rain-proof structure, and by using this light source 12, no moisture-proof and rain-proof structure is provided between the equipment body 13 and the light-transmitting cover 14, etc.
[0011] The light source 12 is long and formed with a moisture-proof and rain-proof structure. The light source 12 is housed in a cylindrical envelope 20 having optical transparency at least in the light irradiation direction, a light source module 21 (not shown) which is a light source unit having a plurality of light-emitting elements such as LEDs, and a power supply unit 22 which converts external power input from the outside into a predetermined lighting power and supplies it to the plurality of light-emitting elements, and both ends of the envelope 20 are sealed by caps 23. A wire having one end connected to an external power input unit of the power supply unit 22 is drawn out from one of the caps 23 through a packing, and the other end of the wire is connected to a power line that supplies external power at the installation site.
[0012] The fixture body 13 is formed long and made of, for example, a metal plate. The fixture body 13 is placed on the placement surface 11 via a cover 15.
[0013] The device body 13 has a rectangular, flat body portion 30 and side edge portions 31 provided on both sides of the body portion 30 in a short direction intersecting with the longitudinal direction.
[0014] The main body 30 is provided with a number of semicircular protrusions 32 protruding from the rear side, a number of mounting holes 33 for attachment to a number of bolts protruding from the installation surface 11, and a wiring hole 34 through which wiring drawn out from the light source 12 can be inserted.
[0015] The side edge 31 is bent so as to protrude in a substantially V-shape toward the front side of the main body 30, with the tip protruding from the rear side of the main body 30. The side edge 31 and the protruding part 32 have substantially the same protruding dimension from the rear side of the main body 30, and are capable of abutting against the cover 15 (or the installation surface 11 when the cover 15 is not used).
[0016] A pedestal 35 is attached to the front side of the main body 30 at both longitudinal ends of the fixture body 13. The pedestal 35 is provided with a screw attachment portion 37 having a screw hole 36 for screwing the light-transmitting cover 14, facing the end face side of the fixture body 13. Furthermore, a pair of attachment springs 38 are attached to the pedestal 35 for detachably holding the light source 12 attached to the fixture body 13.
[0017] The light-transmitting cover 14 is formed in a long length from, for example, a milky white light-transmitting resin material. The light-transmitting cover 14 accommodates and covers the fixture body 13 installed on the installation surface 11 and the light source 12 arranged in the fixture body 13, and is detachably attached to the fixture body 13.
[0018] The translucent cover 14 is box-shaped having a front portion 40, side portions 41 on both short sides of the front portion 40, and end portions 42 on both long sides of the front portion 40, and an opening 43 is formed on the rear side.
[0019] The opening 43 of the translucent cover 14 and the peripheral portion 44 forming this opening 43 are larger than the outer shape of the fixture body 13, allowing the fixture body 13 to be inserted into the opening 43 and to be accommodated therein, while allowing the peripheral portion 44 to be positioned around the fixture body 13.
[0020] The side surface portions 41 on both sides are formed into an inclined surface so as to have a tapered shape toward the front surface portion 40, or so as to have a shape that widens from the front surface portion 40 side toward the opening portion 43 side.
[0021] The end surface portions 42 at both ends are formed substantially perpendicular to the front surface portion 40. The end surface portions 42 at both ends are formed with mounting holes 46 at the positions of the peripheral portions 44 of the opening 43, through which mounting screws 45 such as decorative screws for mounting the light-transmitting cover 14 to the fixture body 13 are inserted. During installation, with the fixture body 13 accommodated in the opening 43, the mounting holes 46 face the screw holes 36 of the screw mounting portion 37 of the fixture body 13 substantially coaxially, so that the mounting screws 45 inserted through the mounting holes 46 can be screwed into the screw holes 36 of the screw mounting portion 37. Furthermore, the end surface portions 42 at both ends are formed with drainage holes 47 at positions near the front surface portion 40 side for draining rainwater and the like that has entered the light-transmitting cover 14.
[0022] The cover 15 is formed into a long shape, for example, from a metal plate. When the fixture body 13 is installed on the installation surface 11, the cover 15 is interposed between the installation surface 11 and the fixture body 13.
[0023] The cover body 15 has a mounting portion 50 and cover portions 51 and 52 that rise from the periphery of the mounting portion 50.
[0024] The installation section 50 is in the shape of a rectangular flat plate, and is formed to be larger than the longitudinal and lateral dimensions of the fixture body 13 and the light-transmitting cover 14. The installation section 50 is provided with a mounting hole 53 and a wiring hole 54 corresponding to the positions of the mounting hole 33 and the wiring hole 34 of the fixture body 13. Furthermore, the installation section 50 is formed with a plurality of opposing holes 55 corresponding to the positions of the plurality of protrusions 32 of the fixture body 13.
[0025] Covering portions 51 on both sides are bent toward the front side and raised from both sides in the short direction of the installation portion 50, and covering portions 52 on both sides are bent toward the front side and raised from both ends in the long direction of the installation portion 50. The covering portions 51 and 52 are bent, for example, at approximately right angles from the installation portion 50.
[0026] The covering portions 51 and 52 cover the periphery of the peripheral portion 44 of the light-transmitting cover 14 which is attached to the fixture body 13 which is combined with the installation portion 50 .
[0027] The cover parts 51 on both sides face and cover the peripheral parts 44 of the side parts 41 on both sides of the light-transmitting cover 14. A gap part 56 that allows the light-transmitting cover 14 to be attached and detached is formed between the cover part 51 and the side part 41. The distance of the gap part 56 between the cover part 51 and the side part 41 is formed to be narrower toward the installation part 50, which is the back side, than the opening side of the gap part 56, because the side part 41 is inclined.
[0028] The cover portions 51 on both sides may be inclined so as to widen from the installation portion 50 and may be formed so as to narrow toward the installation portion 50, which is the back side of the opening side of the gap portion 56. In this case, the side portion 41 may or may not be inclined.
[0029] The cover parts 52 on both ends face and cover the peripheral parts 44 of the end face parts 42 on both ends of the light-transmitting cover 14. A gap is provided between the cover parts 52 and the end face parts 42 to allow the light-transmitting cover 14 to be attached and detached. The cover parts 52 are disposed approximately parallel to the screw attachment parts 37 of the device body 13 and the end face parts 42 of the light-transmitting cover 14.
[0030] A pressing portion 57 is provided at the center of the cover portions 52 on both ends, the pressing portion 57 having a larger protruding dimension from the installation portion 50 than the cover portions 51 on both ends. The pressing portion 57 is provided with an insertion portion 59 having an insertion hole 58 through which the mounting screw 45 is inserted.
[0031] Next, when installing the lighting device 10 on the installation surface 11, a pair of bolts protruding from the installation surface 11 are inserted into a pair of mounting holes 53 in the cover 15 and a pair of mounting holes 33 in the fixture body 13, and the nuts are screwed and tightened. As a result, the fixture body 13 is installed on the installation surface 11 with the installation part 50 of the cover 15 sandwiched and held between the fixture body 13 and the installation surface 11.
[0032] Both ends of the light source 12 are attached to the mounting springs 38 at both ends of the fixture body 13, and the light source 12 is disposed in the fixture body 13. The wiring drawn from the light source 12 is electrically connected to a power supply line drawn from the installation surface 11 in advance when the fixture body 13 is installed.
[0033] The light source 12 and the fixture body 13 are accommodated in the opening 43 of the light-transmitting cover 14. The peripheral portion 44 of the light-transmitting cover 14 is disposed around the fixture body 13 and is disposed inside the covering portions 51, 52 of the covering body 15, and the tip surface of the peripheral portion 44 abuts against the front side of the installation portion 50 of the covering body 15. In this state, the insertion hole 58 of the covering body, the mounting hole 46 of the light-transmitting cover 14, and the screw hole 36 of the fixture body 13 are disposed on approximately the same axis.
[0034] The light-transmitting cover 14 is attached to the fixture body 13 by screwing and tightening the mounting screws 45 through the insertion holes 58 of the cover body and the mounting holes 46 of the light-transmitting cover 14 into the screw holes 36 of the fixture body 13.
[0035] Furthermore, the lighting device 10 is turned on when power is supplied to the light source 12, and light from the light source 12 passes through the light-transmitting cover 14 and is irradiated to the outside.
[0036] Furthermore, even if the lighting device 10 is installed in an environment where wind blows in, the periphery between the installation portion 50 of the covering body 15 and the peripheral portion 44 of the light-transmitting cover 14 is covered with the covering portions 51, 52 of the covering body 15, so that it is possible to reduce wind from entering the inside of the light-transmitting cover 14. This reduces the occurrence of rattling caused by the light-transmitting cover 14 being pushed from the inside by wind entering the inside of the light-transmitting cover 14, and therefore reduces the load on the mounting hole 46 of the light-transmitting cover 14 through which the mounting screw 45 is inserted.
[0037] Furthermore, since the cover portion 52 is provided with an insertion portion 59 through which the mounting screw 45 is inserted, the tightening force of the mounting screw 45 is received by the cover portion 52, and the force applied to the translucent cover 14 can be reduced, thereby further reducing the load on the mounting hole 46 of the translucent cover 14 through which the mounting screw 45 is inserted.
[0038] In addition, the gap 56 between the side portions 41 on both sides of the translucent cover 14 and the cover portion 51 of the covering body 15 is formed so as to become narrower toward the installation portion 50, which is the back side of the opening side of the gap 56, so that wind is less likely to enter the gap 56 and rattling of the translucent cover 14 can be reduced, and even if rainwater or the like does enter the gap 56, it can easily flow out of the gap 56.
[0039] By inclining the side portions 41 on both sides of the light-transmitting cover 14, the relationship of the gap 56 described above can be realized, and rainwater and the like can easily flow off without remaining on the surface of the side portions 41.
[0040] Moreover, since the cover 15 is provided separately from the device body 13, it can be used only when the installation environment requires measures against wind.
[0041] Incidentally, the cover body 15 may be provided integrally with the fixture body 13, which can reduce rattling of the light-transmitting cover 14 and reduce the number of parts.
[0042] Also, the covering body 15 may be formed in a frame shape with a large opening in the inner region of the installation section 50. This inner opening of the installation section 50 can reduce the weight of the covering body 15, and the installation surface 11 and the bolts protruding from the installation surface 11 can be seen from the inner opening of the installation section 50 when placing the covering body 15, improving workability.
[0043] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
