JP 9-237610 A (Embodiment of the Invention, FIG. 5)

  However, the reflecting surface 103 of the reflecting mirror 104 is formed by forming the reflecting surface 103 on the inner surface of the reflecting mirror 104 formed in a trumpet shape from glass, metal, resin, etc. by aluminum vapor deposition or white coating. Due to heat generation of the filament or the like due to continuous use, the surrounding reflective surface is exposed to a high temperature, and there is a problem that the reflectance is significantly lowered due to discoloration or peeling.

  Therefore, in facilities with particularly large scales such as factories and warehouses, the number of lighting increases, and the cost of lighting increases. For this reason, the illumination which can reduce the cost concerning illumination at least, without reducing illumination intensity is desired.

  The present invention was devised in view of the above points, and has a reflectivity of 90% or more and no discoloration or peeling by coating high purity titanium or silicon on an aluminum plate by a vacuum deposition method. Provided is a lighting fixture having a reflecting surface.

  In order to achieve the above object, a luminaire including a lamp according to the present invention includes a holder that is suspended from a ceiling by an electric cord, and a reflector that is attached to the holder and has a reflective surface formed on the inner surface thereof. The lamp is attached to the socket of the holder and is located inside the reflector.

  Here, by replacing the existing shade with a reflecting umbrella having a reflecting surface formed on its inner surface, the illumination environment can be improved by increasing the illuminance without increasing the number of lamps.

  In order to achieve the above object, a luminaire provided with a lamp according to the present invention includes a holder that is suspended from the ceiling by an electric cord, and a holder that can be attached to the holders of these various forms. A reflective umbrella having a portion and an umbrella portion, an octahedral reflective surface attached to the inner surface of the umbrella portion of the reflective umbrella, and a lamp attached to the socket of the holder and positioned inside the reflective umbrella.

  Here, even when the existing shade is removed and the reflector is attached, the mechanism can be attached as it is by the holder attaching portion that can be attached to various holders.

  In order to achieve the above object, a luminaire provided with a lamp according to the present invention takes a socket base provided in the projector body in a projector body in which a front glass is attached to the front opening end. A socket to be attached, a reflecting plate attached to an opening edge of the socket base and having a reflecting surface formed on an inner surface thereof, and a lamp attached to the socket and positioned inside the reflecting plate.

  Here, the lamp attached to the socket provided in the projector is surrounded by a reflecting plate having a reflecting surface formed on the inner surface thereof, thereby improving the lighting environment by increasing the illuminance without increasing the number of lamps.

  In addition, since the reflecting surface has a reflectance of 90% or more, it can be replaced with a low-wattage lamp because the brightness is 150% to 240% compared to the conventional reflector, greatly reducing running costs. Is achieved.

  In addition, by making the reflector or reflector into a truncated cone or polygonal cone, it is easy to adjust the illumination angle of the lighting fixture according to the mounting height of the lighting fixture or the type and capacity of the lamp. Can be done.

  By coating the reflective surface with titanium oxide, no discoloration or peeling occurs, and the chargeability is close to 0, making it difficult for oil mist or the like to adhere.

  In the luminaire provided with the lamp of the present invention having the above-described configuration, it is possible to increase the illuminance as compared with the conventional luminaire by attaching a shade having a reflective surface with a high reflectivity. This can be realized by using a lamp with lower power consumption than the lamp, and as a result, there is an effect that the cost for illumination can be reduced while maintaining the illuminance.

  Further, by using a metal material having a reflectance of 90% or more for the reflecting plate, it is possible to use a lamp with low power consumption of 30 to 75% in the same type of lamp. For example, a 700 W mercury lamp can be used as a lamp by using a lighting fixture having a reflective surface with a reflectance of about 95% in a building having a ceiling height of 10 m, which conventionally uses a 1000 W mercury lamp. In addition, a 200 W mercury lamp can be used in a building having a ceiling height of 6 m that conventionally uses a 400 W mercury lamp.

  Recently, suppression of carbon dioxide emission has been screamed to prevent global warming. The increase in power consumption due to lighting and air conditioning is one of the reasons for this carbon dioxide, and it is required to realize operation by energy saving in each factory. By using the lighting apparatus according to the present invention, suppression of carbon dioxide can be achieved. It becomes possible.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention.
FIG. 1 is an explanatory front view for explaining an example of a lighting fixture including a lamp to which the present invention is applied.

  The luminaire 1 shown here includes a holder 4 suspended from a high ceiling 2 of a facility by an electric cord 3, a reflector 6 attached to the holder 4 and having a reflecting surface 5 formed on the inner surface thereof, and the holder 4 The lamp 8 is attached to the socket 7 and located inside the reflector 5.

  As shown in FIGS. 2 (a), 2 (b), and 2 (c), the reflector 6 is formed by vacuum deposition on an aluminum plate having a total light reflectance of 95% of the reflective surface 5 of the reflector 6. Titanium, silicon, etc. are coated.

  Therefore, the reflecting umbrella 6 shown in FIG. 2 (a) is aligned with the upper end opening edge of the polygonal surface 9, 9,... Of the cylindrical body 10 that is bent so that the polygonal surfaces 9, 9,. The ceiling surface 11 is joined to the rivet 12 or the like, and the attachment hole 13 to the holder 4 that is parallel to the outer peripheral surface is attached to the upper end opening edge.

  The mounting hole 13 has a shape matching the socket 7 provided in the holder 4, and is attached to the end surface of the holder 4 with a fastening screw 14 or the like as shown in FIG. A screw hole 15 is drilled around the mounting hole 13.

  Next, the reflector 6 shown in FIG. 2 (b) has an outer peripheral surface of the cylindrical body 10 at the upper end opening edge of the polygonal pyramid-shaped cylindrical body 10 that is bent so that the polygonal surfaces 9, 9,. A mounting hole 13 is attached to the holder 4 that is parallel. A screw hole 15 is formed around the mounting hole 13.

  In addition, the reflector 6 shown in FIG. 2C is configured such that a mounting hole 13 to the holder 4 that is parallel to the outer peripheral surface of the cylindrical body 10 is attached to the upper end opening edge of the cylindrical cylindrical body 10. . A screw hole 15 is formed around the mounting hole 13.

  As described above, in the present embodiment, as shown in FIGS. 3A, 3B, and 3C, a conventionally known shade (not shown) is removed from the holder 4, and the reflector 6 of the present invention is removed. Is attached to the end surface of the holder 4 from the screw hole 15 around the mounting hole 13 with a fastening screw 14 or the like. Then, a lamp 8 such as a mercury lamp is screwed into the socket 7 and attached.

  In the case of the reflector 6 as shown in FIG. 3A, when a lower end opening width w is larger than the height h of the cylindrical body 10 and illumination from a relatively low position or a small mercury lamp is used. This is effective because the irradiation range is limited.

  Further, in the reflector 6 as shown in FIGS. 3B and 3C, the lower end opening edge w is made smaller than the height h of the cylindrical body 10 so that illumination from a high ceiling such as a warehouse or a factory or large-scale mercury is performed. This is effective because the irradiation range can be enlarged downward when using a lamp.

  Next, FIG. 4 is a perspective view for explaining another example of a reflector umbrella of a lighting fixture having a lamp to which the present invention is applied, and FIG. 5 is a perspective view showing the inside of FIG.

The reflector 6 shown here is composed of an aluminum alloy and a cylindrical holder mounting part 25 at the upper part and a hemispherical umbrella part 26 formed at the lower part thereof.
An attachment hole 13 for inserting a socket is formed in the center of the upper end surface of the holder attachment portion 2, and a screw hole 15 for attachment to the holder is provided around the attachment hole 13.

  Therefore, the screw hole 15 is provided at a position corresponding to a holder handled by each manufacturer, and even if the existing shade 6 is removed and the reflector 6 of the present invention is attached, the screw hole 15 can be attached as it is. It is a mechanism.

  A reflecting surface 5 made of an octahedron is provided around the inner surface of the umbrella portion 26 of the reflecting umbrella 6. The reflecting surface 5 made of octahedron is such that titanium, silicon or the like is coated on an aluminum plate having a total light reflectance of approximately 95% by a vacuum deposition method.

  Therefore, a constant high illuminance can be obtained without reducing the illuminance around the work area under the luminaire 1.

  Next, FIG. 6 is a partially cutaway side view for explaining another example of a lighting fixture including a lamp to which the present invention is applied, and FIG. 7 is a front view of FIG.

The luminaire 1 shown here represents an outdoor projector, and a socket base 18 is provided in a projector main body 17 having an opening edge at the front, and the socket 7 is attached in the socket base 18.
A polygonal pyramid-shaped reflector 19 is attached to the opening edge of the socket base 18 so that the polygonal surfaces 9, 9,... Are formed, and the front surface along the opening edge of the projector main body 17 is attached. After the packing 20 and the front glass 21 are fitted, the front frame 22 is attached in a sealed manner by the frame attachment screw 23.

  Further, the projector main body 17 is connected to the arm 16 by a knob screw 24 so as to be rotatable, so that the light projection angle can be freely adjusted.

  The luminaire 1 of the present invention having the above-described configuration has lower power consumption than the lamp of the luminaire provided in a conventional warehouse or the like by the high reflectance reflector 6 having a total light reflectance of approximately 95%. By using the lamp, it is possible to obtain illuminance that is the same as or higher than that in the conventional warehouse.

  Further, by coating the reflective surface 5 with high-purity titanium, silicon, or the like by a vacuum deposition method, there is no discoloration or peeling, and the chargeability is close to 0, making it difficult for oil mist or the like to adhere. Moreover, even if there is some dirt, it is possible to recover the reflection efficiency to almost 100% by gently washing the reflector with a medieval detergent at the time of lamp replacement.

  As described above, when the lighting fixture 1 is used in a warehouse where a lighting fixture using a mercury lamp is conventionally installed, the lamp can be replaced with a mercury lamp with lower power consumption. In general, the lamp has low power consumption. As the price becomes lower, lamps that are more expensive than mercury lamps, such as metal halide lamps (MF lamps) and CDM lamps, but have high brightness (with the same power consumption as mercury lamps, higher power consumption) A lamp with low power consumption such as a lamp having a luminance equivalent to that of a mercury lamp can also be used.

  For example, a 700 W mercury lamp can be used by using a reflector having a reflective surface with a reflectivity of 95% or more in a warehouse with a ceiling height of 10 m, which conventionally uses a 1000 W mercury lamp, Further, in a warehouse having a ceiling height of 6 m, which conventionally uses a 400 W mercury lamp, a 200 W mercury lamp can be used, and the power consumption can be greatly reduced.

  Further, in the case of a warehouse using the 1000 W mercury lamp, the illuminance which was 140 LUX in the past is improved to 300 LUX by using the reflector of the present invention instead of the conventional shade. In addition, in the case of a warehouse using the 400 W mercury lamp, the illuminance, which was 140 LUX in the past, is improved to 600 LUX by using the reflector of the present invention instead of the conventional shade.

  Further, since the reflector umbrella is inclined and spreads from the upper end side inner peripheral surface toward the lower end side inner peripheral surface, the light from the lamp is reflected at a predetermined reflection angle and projected downward. Therefore, as shown in FIGS. 2 (a), 2 (b), and 2 (c), reflectors having different inclination angles of the inner peripheral wall are selected according to the mounting height of the lighting fixture or the type and capacity of the lamp. The attachment angle of the lighting fixture can be easily adjusted.

  Therefore, by adjusting the irradiation angle, the range and illuminance in which light is irradiated by one predetermined lighting fixture are adjusted.
