  Hereinafter, specific structures of the reflector, the lighting fixture, and the lighting device according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 4, the luminaire 1 according to the first embodiment detachably attaches the light bulb 3 to the socket 2 suspended from the ceiling of the building, and detachably attaches the adapter 4 to the socket 2. A reflector 5 is detachably attached to the adapter 4, and a cover 6 is detachably attached to the reflector 5.

  The structure of each part of the lighting fixture 1 will be described below. For the socket 2 and the light bulb 3, commercially available general-purpose products can be used.

  First, the structure of the adapter 4 will be described. The adapter 4 is composed of an upper adapter 7 attached to the socket 2 and a lower adapter 8 attached to the reflector 5 as shown in FIGS. 4 and 5. .

  The upper adapter 7 is formed with an annular collar 10 at the upper end of a cylindrical body 9, a through hole 11 is formed in the collar 10, and the socket 2 and the upper adapter 7 are bolted using the through hole 11. 12 and nut 13 are detachably fastened.

  The upper adapter 7 has a screw 14 screwed to the lower end portion of the main body 9.

  On the other hand, the lower adapter 8 is formed with an annular collar 16 at the lower end of a cylindrical main body 15, and a through hole 17 is formed in the collar 16. The adapter 8 is detachably fastened with bolts 18 and nuts 19.

  Further, the lower adapter 8 has a pair of front and rear spiral guide grooves 20 formed on the outer peripheral surface of the main body 15.

  The adapter 4 engages a screw 14 screwed into the upper adapter 7 in a guide groove 20 formed in the lower adapter 8, and rotates the upper adapter 7 relative to the lower adapter 8. The screw 14 of the upper adapter 7 moves along the guide groove 20 of the lower adapter 8, so that the upper adapter 7 moves up and down with respect to the lower adapter 8.

  Therefore, as shown in FIG. 4, when the upper adapter 7 is moved upward with respect to the lower adapter 8, the light bulb 3 is also moved upward (refer to the left side of FIG. 4), while the lower adapter 8. In contrast, when the upper adapter 7 is moved downward, the light bulb 3 also moves downward (see the right side of FIG. 4).

  Further, the adapter 4 can fix the upper adapter 7 to the lower adapter 8 by screwing a screw 14.

  Next, the structure of the reflector 5 will be described. As shown in FIGS. 6 to 9, the reflector 5 is formed with an annular collar 22 at the upper end portion of the substantially bowl-shaped main body 21. A through hole 23 is formed, and the reflector 5 and the lower adapter 8 are detachably fastened with a bolt 18 and a nut 19 using the through hole 23.

  In addition, the reflector 5 is formed with an annular step 24 at the lower end of the main body 21 so that the grid-like cover 6 can be inserted inside the step 24, while the cover is provided outside the step 24. The hook 25 attached to 6 can be locked.

  The reflector 5 has a reflection surface 26 that reflects light emitted from the light bulb 3 downward on the inner periphery.

  As shown in FIG. 8, the reflecting surface 26 is formed in a polygonal cross section on the upper side of the reflector 5 so that the light reflected by each surface 27 is diffused in a relatively wide range, and the irradiation distance is relatively long. On the other hand, as shown in FIG. 9, the lower side of the reflector 5 is formed in an arc cross section so that the light reflected by the peripheral surface 28 is condensed in a relatively narrow range, The irradiation distance is increased.

  In this way, the reflector 5 has a short-distance illumination reflecting surface 29 whose irradiation distance is relatively close to the inside and a long-distance illumination reflection surface 30 whose irradiation distance is relatively far up and down integrally and continuously. 8 is a short-distance irradiating reflection surface 29 that is shorter than the irradiating distance when the light from the light bulb 3 is reflected by the long-distance irradiating reflecting surface 30. As shown in FIG. 9, the long-distance illumination reflecting surface 30 is formed in a polygonal cross-section, and the irradiation distance is longer than the irradiation distance when the light from the bulb 3 is reflected by the short-distance illumination reflecting surface 29. As shown in FIG.

  In this reflector 5, a short-distance illumination reflective surface 29 and a long-distance illumination reflective surface 30 are integrally formed simultaneously by pressing an aluminum plate.

  As described above, the luminaire 1 connects the light bulb 3 to the reflector 5 via the adapter 4, and the short-distance irradiating reflecting surface 29 and the irradiating distance are relatively close to the inside of the reflector 5. The reflecting surface 30 for long-distance irradiation that is relatively far is formed vertically.

  And in the said lighting fixture 1, the adapter 4 is comprised so that the position of the light bulb 3 can be changed up and down.

  Therefore, in the luminaire 1, when the position of the bulb 3 is changed up and down by the adapter 4, the relative position between the reflecting surface 26 of the reflector 5 and the bulb 3 changes accordingly.

  Thereby, in the said lighting fixture 1, an irradiation distance is changed with the case where the light radiated | emitted from the light bulb 3 is reflected by the reflective surface 29 for short distance irradiation, and the case where it is reflected by the reflective surface 30 for long distance irradiation. Can do. Therefore, in the said lighting fixture 1, the irradiation distance of the lighting fixture 1 can be easily adjusted with the adapter 4 in a construction site.

  Moreover, in the said lighting fixture 1, even if it is a case where the existing lighting fixture 1 is replaced | exchanged, even if the size of the existing light bulb 3 and the socket 2 differs for every manufacturer, the position of the light bulb 3 is moved up and down by the adapter 4. Since it can be changed, a desired irradiation distance can be obtained by using the existing light bulb 3 and the socket 2 as they are.

  Further, in the lighting device 1, the short-distance illumination reflecting surface 29 is formed on the upper side of the reflector 5, and the long-distance illumination reflecting surface 30 is formed on the lower side of the reflector 5.

  Therefore, in the luminaire 1, when the light bulb 3 is positioned on the upper side of the reflector 5 by the adapter 4 and the light bulb 3 is retracted back when viewed from the outside, the irradiation distance is shortened, When the light bulb 3 is positioned below the reflector 5 by the adapter 4 and viewed from the outside, the light bulb 3 protrudes to the near side, and the irradiation distance becomes long.

  Thereby, in the said lighting fixture 1, since the state of the light bulb 3 visually visible from the outside and the irradiation distance of the lighting fixture 1 can be matched sensuously, the adjustment work of irradiation distance can be made easy. .

  Moreover, in the said lighting fixture 1, while forming the reflective surface 29 for short-distance irradiation in polygonal cross-sectional shape, the reflective surface 30 for long-distance irradiation is formed in circular arc cross-section, The long-distance illumination reflecting surface 30 is integrally and continuously formed.

  Therefore, in the said lighting fixture 1, while being able to achieve weight reduction of the reflective umbrella 5, manufacture of the reflective umbrella 5 can be made easy.

  As shown in FIGS. 10 and 11, the lighting fixture 31 according to the second embodiment has the reflector 5 attached to the lower end of the adapter 32 in a detachable manner, and the cover 6 is detachably attached to the reflector 5. . In addition, in the following description, the same code | symbol is attached | subjected to the member which has the same function as the lighting fixture 1 which concerns on Example 1, and description is abbreviate | omitted.

  The adapter 32 is attached to the inner upper end of the casing 33 having an opening at the lower end with a pair of left and right guide bodies 34 and 35 extended vertically, and a disc-shaped moving plate 36 is vertically mounted on the guide bodies 34 and 35. A spring 37 is interposed between the upper surface of the movable plate 36 and the inner upper end of the casing 33, and nuts 38, 39 are attached to the screw portions formed on the outer periphery of the guide bodies 34, 35. The socket 2 that holds the light bulb 3 is attached to the lower surface of the moving plate 36. The lower end portion of the spring 37 is fitted into a recess formed on the upper surface of the moving plate 36, thereby preventing the spring 37 from overturning.

  The adapter 32 is formed with a pair of left and right bosses 40, 41 on the outer peripheral surface of the casing 33, and a fixture 42 is attached to the bosses 40, 41 so that the angle can be adjusted. In the figure, 43 and 44 are fixing screws.

  The adapter 32 has three ribs 45 formed at intervals of 120 degrees on the lower inner peripheral surface of the casing 33, and the reflector 5 is detachably attached to the casing 33 with screws 46 screwed to the lower ends of the ribs 45. Yes.

  Then, as shown in FIG. 12, the adapter 32 can move the moving plate 36 up and down by nuts 38 and 39, so that the vertical position of the socket 2 can be changed inside the casing 33. .

  As described above, in the luminaire 1 according to the first embodiment, the adapter 4 is interposed between the socket 2 and the reflector 5. However, in the luminaire 31 according to the second embodiment, the adapter 32 includes the reflector. 5 and a socket 2 for holding the light bulb 3 is accommodated inside the casing 33 of the adapter 32 so that the vertical position can be changed.

  Therefore, in the luminaire 31 described above, the socket 2 only moves up and down inside the casing 33, and it is not necessary to change the external shape of the casing 33. Therefore, the mounting position of the reflector 5 can always be kept constant. In the case where a plurality of lighting fixtures 31 are arranged side by side, the mounting positions of all the reflectors 5 are the same, and the aesthetic appearance can be improved.

  As shown in FIG. 13, the lighting device 47 according to the third embodiment functions as a fish collecting device of the squid fishing boat 48. The support body 50 is attached to the deck 49, and 13 lighting fixtures 31 are attached to the support body 50. It is installed with a gap in the front and rear. In the following description, members having the same functions as those of the lighting fixtures 1 and 31 according to Example 1 or Example 2 are denoted by the same reference numerals, and description thereof is omitted.

  In the support 50, a wire 53 is stretched between the upper ends of a pair of front and rear columns 51, 52, and the columns 51, 52 are formed to be extendable.

  The lighting device 47 is detachably attached to the wire 53 of the support 50, and the upper end of a damper 55 as a vibration absorber is attached to the lower end of the suspension 54. The fixture 42 of the lighting fixture 31 is detachably attached to the lower end of the lamp.

  As described above, in the lighting device 47, since the support columns 51 and 52 of the support body 50 are formed to be extendable and retractable, the mounting position (mounting height) of the lighting fixture 31 can be adjusted simply by extending and retracting the support columns 51 and 52. It can be easily changed.

  Further, in the lighting device 47, since the lighting fixture 31 is connected to the support 50 via the damper 55, vibration can be absorbed by the damper 55, and the lighting fixture 31 always irradiates a certain range. be able to. In particular, when the illuminating device 47 is used as a fish collecting device, it is possible to always irradiate a certain range even if the ship vibrates, and to improve the fish collecting performance.

  The present invention can be applied to a reflector, a luminaire having a reflector, and a luminaire having a luminaire.
