INSTRUCTIONS OF THE INVENTION [Technical Field] The present invention relates to an illumination method mainly by installing a ceiling mounted, outdoor lighting fixture installed in a house, and more particularly relates to a shape of a refracting plate of a lighting fixture Setting method. [Prior Art] Φ In the past, a refracting plate as a illuminating device having a light source bulb and a refracting plate that refracts light from a light source bulb is generally a hemispherical shape. However, in the hemispherical refracting plate, since the light of the light source bulb interferes with each other, the light cannot reach the far side, so if the table lamp on the table is illuminated below the tens of cm, there is no problem, but if it is installed in the factory, When the xenon lamp on the ceiling of the business office is to illuminate the floor surface below from a height of about 3 to 7 m or more, there is a problem of Q that is insufficient in illumination. Further, in the hemispherical refracting plate, it is also possible to improve the illuminance by providing fine concavities and convexities on the inner surface of the inner surface, and diffracting the light to dilute the illuminance, but even if the illuminating device is used, the floor below is raised from a height. When the surface is illuminated, there is also a problem of insufficient illumination. On the other hand, although the inner surface of the refracting plate can be set as a polyhedron to improve the reachability of the refracted light, the i-segment polyhedron having a single inclination angle cannot control the direction of refraction of the light, so it cannot be large. Scope-Uniform Illumination Here, the inventors of the present invention have proposed a refracting plate in which the refractive surface of the inner surface is formed by the inclined portions of three or more stages of different inclination angles of -4-200936939, respectively. According to the multi-segment refracting plate, the light from the light source bulb can be refracted in multiple directions, and the prescribed range can be illuminated by controlling the direction of refraction. However, Patent Document 1 does not disclose a specific control method for the direction of refraction of light from a light source bulb, and therefore it is necessary to control the direction of refraction of light by constantly groping. [Problem to be Solved by the Invention] The object of the present invention is to provide a light-reducing plate having a multi-stage structure disclosed in Patent Document 1 described above. When refracting and illuminating, it is possible to appropriately refract light in accordance with the range in which illumination is necessary. [Means for Solving the Problem] The present invention is an umbrella-shaped refracting plate having a light source bulb and a light surface for refracting a light source bulb, wherein the refracting surface of the refracting plate is inclined by an angle Each of the inclined portions is formed by a plurality of upper and lower inclined portions, and each of the inclined portions is an illumination method performed by a lighting fixture formed by a plurality of plane combinations, wherein when the illumination is concentrated in a predetermined range, the upper and lower inclined portions are mutually The angles of the configuration are all set to be less than 180°, and in order to illuminate the light source bulb in a wider range than the predetermined range, the angle of the upper and lower inclined portions is set to be -5 to 200936939 degrees. Combination of less than 180° and over 180°. As described above, the present invention is characterized in that, in accordance with the size of the necessary illumination range, in other words, it is performed in accordance with concentrated illumination or diffusion (distribution), and the combination of the angles formed by the upper and lower inclined portions is changed. That is, when the predetermined range is illuminating, the angles formed by the upper and lower inclined portions are all set to be less than 180°. As described above, when the entire angle formed by the upper and lower inclined portions is set to be less than 180, the entire refracting plate has an umbrella shape, and the direction of refraction of the light Q is uniform, so that the illumination can be concentrated in a predetermined range. On the other hand, when the angle formed by the upper and lower inclined portions is set to be less than 180° and more than 180°, the direction of the light of the inclined portions is greatly different, so that the refracted light is diffused, which can be large. The range is illuminated. Further, the illumination range can be controlled by adjusting the length of the inclined portion in the vertical direction. In other words, even if the same inclined portion is formed, the angle formed by the light source bulb differs depending on the position in the vertical direction. Therefore, if the length of the upper and lower sides of the inclined portion is long, the light is refracted in a wide range, and the relative Here, when the length of the inclined portion in the vertical direction is short, the light is easily refracted in a certain direction. Therefore, when the illumination is concentrated in a predetermined range, the length of the inclined portion in the vertical direction is shortened as compared with the case where the light of the light source bulb is diffused in order to illuminate a wider range than the predetermined range. Here, in the refracting plate of the lighting fixture used in the present invention, since each inclined portion is formed by a combination of a plurality of planes, the cross-sectional shape is necessarily a polygonal shape, but if the light is uniformly refracted, it is at any place. Both are positive polygons ideal, while positive 16 angles ~ positive 24 angles are more ideal. -6 - 200936939 [Effects of the Invention] According to the present invention, light can be appropriately refracted in accordance with the range of illumination necessary, and light of the light source bulb can be utilized without being wasted and efficiently utilized in accordance with the range of necessary illumination. Therefore, compared with the conventional one, it is possible to reduce the number of light source bulbs or to reduce the output. In this way, it is possible to greatly reduce the amount of electric power used, reduce the amount of heat generation, and improve the air-conditioning efficiency in the building, and contribute to the reduction of the amount of (02). [Embodiment] [The best form for implementing the invention. Hereinafter, an embodiment of the present invention will be described with reference to an embodiment of the present invention applied to a xenon lamp. [Embodiment 1] Fig. 1 is a cross-sectional view showing a first embodiment of a xenon lamp to which the present invention is applied, and Fig. 2 is a view showing the use of the xenon lamp of the present invention. The refracting plate of the xenon lamp, (a) is a bottom view, and (b) is a front view. The xenon lamp 1 shown in Fig. 1 is provided with a light source bulb 1 composed of a metal halide lamp (CDM); The refracting plate 2 for refracting the light of the bulb 1 and the main body portion 3 of the fixed refracting plate 2. The light source bulb 1 is mounted on the top plate portion of the refracting plate 2, and is mounted in a refractory plate 2 in a socket (not shown). As shown in FIG. 2, the refracting plate 2 has a bottom surface shape (transverse sectional shape) of an umbrella shape of 200936939 hexagonal shape, and the refracting surface of the inner surface is a first inclined portion 2a and a second inclination which are different in inclination angles. The portion 2b and the third inclined portion 2c constitute a vertical three-stage structure. The portions 2a to 2c are a combination of a plurality of planes formed by bending one plane, and an angle α formed by the first inclined portion 2a and the second inclined portion 2b, and the second inclined portion 2b and the third portion The angle 々 formed by the inclined portion 2C is set to be less than 18 (Γ. Thereby, the refracting plate 2 is an umbrella shape as a whole as shown in FIGS. 1 and 2, and since the refractive directions of the light are uniform, it is possible to The predetermined range is concentrated illumination. That is, the present embodiment is suitable for the purpose of concentrating and illuminating the light of the light source bulb 1, and as such a use, the light of the light source bulb 1 can be effectively utilized without being used. In this embodiment, the material of the refracting plate 2 is aluminum, and the refractive surface of the inner surface thereof is formed by coating titanium on the surface of the aluminum to form a mirror surface. The material of the refracting plate is not limited to aluminum, and for example, a metal plate may be used to perform mirror processing on the inner surface. Further, the main body portion 3 has an annular support member 3a projecting outward at a periphery of the lower end portion thereof. By placing the support member 3a In the inside of the ceiling raft, the xenon lamp 10 is entirely suspended inside the ceiling T. [Embodiment 2] Fig. 3 is a cross-sectional view showing a second embodiment of a xenon lamp to which the present invention is applied, and Fig. 4 is a view showing a refracting plate used in the lamp of Fig. 3. (a) is a bottom view, and (b) is a front view. In FIGS. 3 and 4, the same components as those in the first embodiment or -8-200936939 are denoted by the same reference numerals, and the description thereof will be omitted. The refracting plate 2 is a refracting surface on the inner surface thereof, and is composed of a first inclined portion 2a, a second inclined portion 2b, a third inclined portion 2c, and a fourth inclined portion 2d each having a different inclination angle. The angle α of the first inclined portion 2a and the second inclined portion 2b is set to be less than 180°, and the angle formed by the second inclined portion 2b and the third inclined portion 2c is not set to exceed 18°. The angle r formed by the third inclined portion 2c and the fourth inclined φ portion 2d is set to be less than 180°. Thus, when the angle formed by the upper and lower inclined portions is set to be less than 180° and more than 180°, the refractive direction of the light is greatly different due to the inclined portions, and is completely set to be less than 180°. In the first embodiment, the light after the refracting is diffused to illuminate a wide range. Further, in the present embodiment, the lengths of the second and fourth inclined portions 2b and 2d are set to be longer than any of the inclined portions of the first embodiment. Even if the same inclined portion is different from the angle formed by the light source bulb 1 by the position in the vertical direction, when the length of the inclined portion in the vertical direction is long, the light is refracted in a wide range. From this point of view, the present embodiment is also suitable for illumination over a wide range. Specifically, in the present embodiment, the xenon lamps 1 are arranged in a plurality of lines in a straight line, and are used as illumination for a wide range, and an area near the lower side of the xenon lamp 10 with the refracted light from the first inclined portion 2a is formed. Illuminating, illuminating the intermediate area of the adjacent xenon lamp with the refracted light from the second inclined portion 2b, and illuminating the area immediately below the adjacent xenon lamp with the refracted light from the second inclined portion 2c to come from The refracted light of the 4th inclined portion-9-200936939 2d illuminates the far side. As described above, in the present embodiment, since the refracting plate 2 is set to illuminate a wide range, illumination can be performed by the interaction of the xenon lamps adjacent to the left and right, and therefore, even if the arrangement interval of the xenon lamps is set to be relatively small In the past, it has been long and has a small output, and the same illuminance as in the past can be obtained. [Embodiment 3] Fig. 5 is a cross-sectional view showing a third embodiment of a xenon lamp to which the present invention is applied, and Fig. 6 is a view showing a refraction plate used in the xenon lamp of Fig. 5, (a) being a bottom view and (b) being a front view . In Fig. 5 and Fig. 6, the same or corresponding components as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted. In the present embodiment, the refracting plate 2 is a first inclined portion 2a, a second inclined portion 2b, a third inclined portion 2c, a fourth inclined portion 2d, and a fifth inclined portion 2e which have different refracting angles on the inner surface thereof. A refracting plate that constitutes the upper and lower five-stage structure. Further, the angle α formed by the first inclined portion 2a and the second inclined portion 2b is set to be less than 180°, and the angle formed by the second inclined portion 2b and the third inclined portion 2c is set to be more than 180°. The angle r formed by the third inclined portion 2c and the fourth inclined portion 2d is set to be less than 180. The angle <5 formed by the fourth inclined portion 2d and the fifth inclined portion 2e is set to be less than 180. Since the present embodiment also sets the angle formed by the upper and lower inclined portions to be less than 180° and more than 180°, the light after the refracting is diffused as compared with the first embodiment which is completely set to be less than 180°. A wide range of lighting. However, in the present embodiment, by setting the angle of the upper and lower inclined portions to -10-200936939 to be close to 18°, it is possible to set a range which is narrower than the second embodiment. That is, this embodiment is interposed between the first embodiment and the second embodiment. As described above, according to the present invention, if the combination of the angles formed by the upper and lower inclined portions of the refracting plate 2 is set, the light can be appropriately refracted according to the range of the necessary illumination, and the light source can be not wasted according to the range of the necessary illumination. The light of the bulb is effectively utilized.产业 [Industrial Applicability] The present invention can be utilized not only in a xenon lamp mounted on a ceiling but also in a lighting fixture installed outdoors, on a wall surface, or on the ground.
