Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a method that can provide women or children to walk safely at night * and can suppress it for those with a sense of crime Criminal consciousness, a roadway lighting method that can improve road safety and is better than anti-offensive roadway lighting, and a roadway lighting device that can achieve such a roadway lighting. [Previous technology] The illuminance of a roadway in a residential area is specified in JIS (Japanese Industrial Standard) Z9111-1988. The average illuminance of the road surface is 3 lx (lux) or more, and the sidewalk centerline is 1.5 away from the road surface. The minimum illuminance of the long axis of the roadway (length direction of the roadway) at a height of m (meter) is perpendicular to the vertical surface (that is, the surface facing the length of the roadway and perpendicular to the roadway surface) is specified to be 0.5 lx or more. Roadway lighting method printed by Shelley Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs. Generally speaking, lighting fixtures are installed on roadway poles, such as electric poles or lighting poles, which are erected at equal intervals on the side edges of the roadway. According to the company, the "Investigation and Research Report on Anti-criminal Lamps" (1992) issued by the Japan Anti-Crime Equipment Association, which accounts for about 80% of the roadway lighting, is the installation of the roadway luminaires on electric poles, and the remaining 20%. Install the roadway lighting equipment on the special lighting pole. Generally speaking, the installation height of the roadway lighting fixtures to the roadway poles (electric poles or lighting poles) is about 4-5m, the installation interval of the roadway lighting fixtures is about 30m to 40m, and the setting of the roadway lighting fixtures The interval is most often in the range of 6 to 9 times the installation height. Regarding illuminance, it is based on the company. According to the survey data of the Kansai Branch of the Illuminating Society, "Reasonable survey and analysis of roadway lighting, 1986 ~ 1990", the average horizontal illumination on the road is about 1 ~ 2 lx, and the other side is -4-the standard of this paper is applicable to Chinese national standards (CNS) A4 specification ⑵㈣97 public love) A5 1 04 2 a? ________B7___ V. Description of the invention (2) The surface is near the middle of the lighting pole, perpendicular to the road surface and facing at the height of 1.5 m on the road facing the surface of the lighting equipment. The surface illuminance is about 0.2 1χ. It is also used to indicate the degree of equality of illuminance on the pavement on the horizontal plane, that is, the uniformity of the illuminance on the road G1 and G2, which is G 1 = minimum illuminance / average illuminance = 0 · 1 ~ 0.18, and G2 = minimum illuminance / Maximum illuminance = 0.02 to 0.04. It can be known from these figures that the road surface illuminance that can be obtained by general roadway lighting does not meet the standard illuminance specified by JIS Z91I 1-1988. This is the actual situation. Most of the lighting fixtures used for roadway lighting are fluorescent lamps which are generally called anti-crime lamps, which are equipped with 20w (watt) fluorescent lamps. Section 13 is a sectional view showing the basic structure of such a conventional general roadway lighting device 1300 in a pattern. The tunnel lighting fixture 1300 is printed by the Shell and Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and includes a lamp tube 1302 stored in a lamp tube storage portion 1301, a stabilizer 1304 stored in a stabilizer storage portion 1303, a reflection plate 1305, and light transparency. The lampshade 1306 is mounted on the roadway pole in a state where the lamp tube storage portion 1301 is positioned on the lower side (that is, the road surface side) of the stabilizer stabilizer storage portion 1303. In addition, the plate for separating the stabilizer storage portion 1303 from the lamp tube storage portion 1301 is also configured to also function as a reflection plate 1305, and is applied on the surface facing the reflection plate 1305 of the tube storage portion 1301. It was pre-coated with white melamin. The light-transmitting lampshade 1306 is made of plastic, and is formed to cover the lamp tube storage portion 1301, and prism cutting is performed on both the lower side portion and the side portion. A cover 1308 is provided around the stabilizer storage portion 1303. . Figure 6 (a) -5- which is also for reference in the description of the embodiment of the present invention -5- This paper size applies to the Chinese National Standard (CNS) A4 specification (2) 0 X 297 mm) A7 B7 Ministry of Economic Affairs wisdom Printed by A5104, Shellfish Consumer Cooperative of the Property Bureau 2 5. In the description of the invention (3), the solid line A indicates the light distribution shape of section A of the conventional general roadway lighting fixture (fluorescent lamp fixture) 1300 shown in Figure i 3 . Section A refers to a plane that is parallel to the side of the roadway in a plane perpendicular to the road surface through the center of the roadway lighting fixture, which is installed at the lighting pole by a mounting accessory, as shown in Fig. 6 (b). In contrast, the surface perpendicular to the side edge of the roadway is called the B-section. It can be seen from the solid line A in FIG. 6 (a) that the conventional roadway lighting fixtures (fluorescent lamp fixtures) 1300 in FIG. 13 are all in the lower area of the lighting fixtures in the A section, and have approximately equal luminosity. Distribution (light distribution curve). In addition to the fluorescent lighting fixture 1300 shown in Fig. 13, part of the roadway lighting fixture also uses a high-voltage discharge lamp such as a mercury lamp of 80W to 250W. Its composition and light distribution on the A section are not significantly different from those of the fluorescent lamp 1300 shown in FIG. 13 and the light distribution curve shown by the solid line A in FIG. 6 (3). [Means to Solve the Problem] Originally, the purpose of roadway lighting was to ensure safe passage for pedestrians walking on the roadway at night. However, in fact, about 50% of road crimes occur at night between 18:00 and 24:00, and the total number of cases is increasing year by year (for example, 'refer to the "Guidelines for the Prevention of Illumination", socially impaired corporation β Japan Anti-crime Equipment Association (July 1997)). Judging from the actual situation of crime on the road as mentioned above, it can be said that the lighting of the previous roadway has problems. People who pass through the roadway at night, especially for the weak women and children, need a kind of pavement that is bright and dark, and it can be felt that "可 -6-This paper standard applies to Chinese National Standard (CNS) A4 Specifications (210 X 297 public love)

Description of the invention (4) Walking on the road with the impression of the heart. Moreover, in the event of a situation, it is necessary to visually recognize the existence or the actions of the suspicious person, the appearance characteristics of the suspicious person, and the brightness required for response measures such as evasion. In contrast, for criminals who commit crimes such as pornography or robbery, they want to have a bright place that is convenient to observe. There are also roadways in the dark where it is convenient for crimes to start. In addition, dark roadways are not only difficult for ordinary people to pass, but also difficult for offenders to commit crimes. At the above points, if you want the impression that the entire roadway is bright, then the average illumination of the road surface must have a certain level or more, and in order to prevent the dark part from being felt, you must have a certain level or higher. Evenness. However, the concept of uniformity is not suggested in the aforementioned JISZ911 1-1988. In order to identify the appearance characteristics of the person under the roadway lighting, the vertical plane illuminance indicating the illuminance perpendicular to the roadway surface must reach a certain level or more. Regarding this point, 'the above-mentioned JIS Z9111-1988 has a standard for illuminance in the vertical plane', but if you want to achieve the vertical illuminance in accordance with the stipulation, it is assumed that the installation height of the lighting fixture is 4.5m and the distance between the lighting poles is 35m. When the maintenance rate required to compensate for the degradation of the speed of light caused by the deterioration of the performance of the lamp tube or the pollution of the lighting fixture is 0.72, the required light intensity of the lighting fixture needs at least about 900cd (Candela). In addition, if the direction in which the light intensity should be achieved is expressed by a vertical angle, the light intensity and its direction (vertical angle) such as "85 degrees" must be set. For lighting equipment using a widely used fluorescent lamp, it is " Extremely difficult to achieve. Secondly, generally speaking, the darker part of the roadway lighting is formed in the phase {¾ Read the precautions on the back before filling out this page) • Binding: CM · This paper size applies the Chinese National Standard (CNg) A4 specification (21 〇X 297 mm) 451 04 2 A7 B7 V. Description of the invention (s) Near the middle of the adjacent roadway pole printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, in order to eliminate the darker parts, it is necessary to increase the Road illumination (horizontal illumination) and vertical illumination. Therefore, more light needs to be distributed to the area near the middle (the vertical angle is around 80 degrees) of the adjacent lighting poles. However, the conventional lighting fixtures, as shown by the solid line A in Fig. 6 (a), have a small amount of light distribution in the directions described above. And if the light distribution amount of the forward lighting device to the above range is excessively increased, the amount of light distribution to the immediate vicinity of the lighting device will be reduced by more than the necessary amount, so it is required to set a proper light distribution shape. Therefore, it is necessary to install an optical system capable of realizing such an appropriate and reasonable light distribution shape on the luminaire. In fact, as far as the structure of the conventional luminaire is concerned, the above-mentioned problems have not been fully considered. As mentioned above, because JIS Z9111-1988 does not mention the concept of uniformity of lighting, in the past, the use of inexpensive 20W (watt) glory lamps is commonly used as a roadway lighting fixture for crime prevention lights, but such lighting fixtures, although It is possible to illuminate the area immediately below the lighting fixture, but as described above, the illuminance near the middle of the adjacent lighting poles is low, and a dark place is formed. Therefore, it not only disturbs the pedestrians who pass through the alleyway at night, but also provides the dark conditions for the villains who intend to commit crimes such as robbery. On the other hand, as described above, in JIS Z9111-1988, the roadway lighting requirements are that the average illuminance on the horizontal plane of the road is 3 lx or more, and the minimum illuminance in the vertical direction of the roadway in the longitudinal direction is 0.51 x or more. However, among these 値, the average 照 3 lx of horizontal plane illuminance is easier to achieve, but the lowest 照 0.5 lx of vertical illuminance in the long axis direction of the roadway is difficult to achieve. This is according to the definition of the vertical plane illuminance in the direction of the long axis of the roadway.

Description of the invention (6) 451042 The minimum value of surface illumination exists, It is on the axis of the crossing of the roadway directly below the lighting fixture. As a result, the lowest value of the illuminance which contributes to the definition of the vertical plane is not the closest luminaire, but any one of the adjacent luminaires. Therefore, if the minimum value of the vertical plane illuminance in the longitudinal direction of the roadway is 0.5 1χ, according to the definition of the vertical plane illuminance in the longitudinal direction of the roadway, the luminosity in that direction must be set to 900cd as described above. the above. However, to achieve this luminosity with roadway lighting appliances generally used in the forward direction, a fluorescent lamp of more than 150W is required, so its cost will inevitably increase. On the other hand, if you want to use a conventional lighting fixture using several 10W fluorescent lamps to achieve the minimum value of 0.5 lx in the vertical direction of the long axis direction of the roadway specified in JIS Z91 1 1-1988, you must shorten the setting interval of the lighting sample. It is 10 ~ 15m, which will increase the installation cost of the roadway lighting. As mentioned above, in the past, the roadway lighting of the vertical illuminance recommended by JIS Z911 and 1988 has actually been achieved, but the actual situation is almost no. The present invention has been made to solve the above-mentioned problems, and its purpose is to provide (1) the weak women and children who can safely pass at night, i, a cheap and inexpensive way to illuminate the laneway, and (2) can achieve the above Roadway lighting equipment. [Means for solving the problem] The roadway lighting method of the present invention is installed at a plurality of branches and roadway poles which are erected along one side edge of the roadway. The height of the roadway rod is 4.5m or more and 6m or less. Lighting equipment, the lighting equipment is installed A plurality of roadway poles are arranged along the roadway at intervals of 30m to 40m, and the roadway is illuminated by lighting the roadway. 9- This paper scale is applicable to the ten national standards (CNS) A4 (2 丨 〇X297 mm) < Please read the precautions on the back before filling in this page.

Description of the invention (9) The lighting apparatus suitable for realizing the roadway lighting method of the present invention is described in order as follows. First, the "inventor of the present case" has reviewed the roadway illumination method for solving the above-mentioned problems in the past. In terms of ships, the survey data of the Kansai Branch of the Illumination Society (Document: (Society of Legal Persons) Kansai Branch of the Illumination Society, "Survey and Analysis of Roadway Lighting Rationalization J (1 ~ 5) J '(1986 ~ 1990) The survey data is based on the selection of brighter street lighting in 40 places where the street illuminations of residential streets or residential streets have different illumination levels, and evaluated by 20 people (women and children). The results are shown in Figure 2. Figure 2 shows the minimum 値 and average 値 of the horizontal illuminance on the horizontal and vertical axes of the figure, respectively. ) Of the roadway lighting, if thanked] more than 50% of those who are evaluated as walking with ease can be marked with a black circle symbol, and more than 50% of those who are evaluated as being unable to walk with peace can be marked with a white square symbol. Consumption cooperative prints the results from the second trap "In order to make it easy for returning female children to walk, the average illuminance at the horizontal plane is set to above 3 lx and the minimum is set to above 0.5 lx In contrast, a bright alleyway is not the right environment for criminals who want to offend on the road, such as robbery or pornography. This is because if the alleyway is brightly lit, it will make the opponent you are looking at right away. Detecting suspicious people nearby and approaching, and taking countermeasures such as evasion, etc.-12- This paper size is applicable to the 0-country standard < CNS) A4 size (210 X 297 mm) 451042 A7 ___B7_ V. Description of the invention (10) Therefore, the brightly illuminated roadway will have various psychological effects on those who want to commit crimes, for example, they have to think about whether the criminal behavior will be found by residents in remote places and their length Issues such as equality, clothing, and human equality are easy for the other party to detect, and whether the escape direction is easy to identify. Therefore, it can have the effect of suppressing intent. Based on the above-mentioned viewpoint, the inventor of this case focuses on establishing a The offending person can psychologically feel the bright aisle lighting, which will help to improve the anti-crime effect with a small amount of money. Review of the roadway lighting methods that can be realized. As a result, the main factors that make people feel bright psychologically can be roughly two. The first is to give the offending person "they are illuminated by the roadway. The lighting of the appliance makes it easy to perceive the characteristics of its appearance ". The impression is influenced by what is seen by a pedestrian illuminated by the closest luminaire. What a passer-by sees depends on the vertical illumination of the passer-by. On the other hand, the other item is to give the impression that the road surface as a whole is bright and not dark. The impression is affected by the road illumination and its uniformity. Printed by the Shelley Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the second stage of the review is to determine the extent to which pedestrians are exposed to vertical illumination. The question of abandoning the crime J will be reviewed based on experiments. The experiment is to form an area imitating the roadway in the square outside the house, and set up the roadway lighting equipment to pretend that one of the pedestrians is the subject of the bottle inspection (observer) and make him stand Next, the vertical illumination of the observed person and the position of the person (observer) who will observe the observation are changed into various different pieces. 13- This paper size applies the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) Printed by 451 042 A7 B7, Shellfish Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 5. Inventory ("), and whether it is possible to grasp the body shape of the observed person's clothing (including color), Questions about the extent to which features, such as the general situation of the appearance, were told to a third party, let five people make subjective evaluations and implement them. The experimental results show that the appearance of the pedestrians in the roadway can be seen. Compared with the vertical illuminance in the direction of the long axis of the roadway, it is easily affected by the vertical illuminance on the face of the lighting device closest to the pedestrian. Regarding this point, as further explained, in FIG. 3, the point P above the lane transverse axis 32 passing directly below the lighting fixture 3b is in accordance with the vertical plane 31 of the lane major axis direction 31 of the lighting fixture 3b. Illuminance Evl is zero by definition. Therefore, a person who is useful for the vertical illuminance of the roadway long axis direction 31 at the point P is not the light 30b from the nearest lighting fixture 3b, but the light 30a adjacent to the lighting fixture 3a. However, in fact, the point P is far away from the lighting device 3a, and the vertical illuminance Evl that can be obtained must be far lower than the benchmark of HS Z911 1-1988. However, in this situation, in fact, the existence or characteristics of the observed person at point P can still be grasped by the observer. That is, because the observed person is illuminated by the light 30b of the closest luminaire 3b, the vertical illuminance Evw at the point P facing the surface of the luminaire 3b is high. In addition, in the description of this case, the "face facing the lighting fixture" at a certain point refers to the vertical line drawn from the point (point P in the above example) to the road surface and the lighting fixture ( In the above example, the plane of the lighting device 3a or 3b) drawn from the vertical line of the road surface is a vertical surface. If the actual measurement method is used for illustration, the illuminance meter will be used at the measurement point so that its measurement surface (light incident surface) is perpendicular to the road surface and faces the measurement object. -14-This paper applies national standards (CNS > A4 specification (210 X 297 mm) -------.-------- (¾Read the ^ -face notice ^: Fill this page) is 451 042 Patent Application No. 88116617 a7 Chinese Correction page of the manual (June 90) B7 V.

Moreover, people are actually not "flat plates", but cylindrical imaginary objects with irregularities. At any position on the roadway, the light will shine on its side half Therefore, as long as the illuminance of the vertical surface facing the surface of the closest lighting appliance is above a certain value, the appearance characteristics can be visually recognized. In the Ministry of Economic Affairs, the employee consumer cooperatives printed by Pei {Please read the back first (Notes on this page will be re-filled on this page) Figure 4 shows the ratio of the testees (observers) judged to be able to identify the characteristics of the passer in the presence of a passerby who is standing in a certain position on the lane.

Whether a person who is guilty of crime will ever think about it should be judged on the basis of what he sees from the circumstances of the visible passers-by. If it is necessary to provide the roadway lighting sufficient to determine that the characteristics of pedestrians can be fully identified to obtain the crime suppression effect, the vertical illuminance of the side facing the lighting equipment must be set to at least 50% according to Figure 4. A person will judge that the level of the characteristics of a passerby can be more than 0.5 ιχ. Secondly, use a roadway model with a scale of 1/25 and set various uniformity of illumination, such as: "Women and children can walk on the roadway at night at ease", "Police at night glance at the road can tell the existence of suspicious persons and No ", and" Those who have intentions don't feel dark ", implement the points -15- This paper size applies the standard of Chinese families (CNS > Α4 specification (210 × 297 mm) 451 04 2 Employees’ consumption of Intellectual Property Bureau Cooperative printed A7 B7 V. Invention description (13) is seven grades ("Excellent J," Good J, "Slightly better", "Permissible", "Slightly worse", "Bad", "Very bad") The subjective evaluation experiment of the evaluation. The experimental results show that among the above three viewpoints, the uniformity of the "permissible" evaluations can be given. The highest requirement is the view that "women and children can walk in the lane at night at ease". Therefore, In Figures 5 (a) and (b), in view of the above-mentioned "women and children can rest assured walking at night", the uniformity of illumination G1 (refer to Figure 5 (a)) and uniformity of illumination G2 (see Circle 5 (b)) and subjective evaluation The relationship between the price. From the fifth circle (a) and (b), we know that if the average illuminance is 3 ~ 5 lx, the uniformity of the illuminance G1 is set to above 0 · 17, or the average illuminance is 3 ~ 5 lx When the uniformity of illumination G2 is set to 0.08 or more, you can obtain the reassurance of Viewpoint 1 of "Women and children can walk at night at night". As for the other two views, since it has been allowed to compare with " Women and children can view the result of the low level of uniformity in the walking lane J at night. Therefore, as long as the average level of illuminance and the level of uniformity in illuminance are met as described above, the remaining two points can be satisfied. The uniformity required for all viewpoints. In addition, if the average illuminance is 1 lx, it is necessary to set the illuminance uniformity G 1 to 0.41 or more or the illuminance uniformity G2 to a higher level than 0.21. At the second stage, if you want to make women and children walk safely at night, then the average horizontal illumination on the pavement is 3 lx, and the minimum horizontal illumination is 0.5 lx. If you replace it with uniform illumination G1 , G = 0.17 (= 0.5 / 3) It is consistent with the experimental results described above with reference to the fifth circle.

In the vicinity of the opposite intermediate point 4 ', not only the road surface is dark, but also people near it look dark. Therefore, if the person located near the darkest opposite intermediate point 4 makes the vertical surface of the surface facing either direction of the lighting fixtures 3a and 3b irradiated by at least 0.5 lx or more, the person located in the lane 1 other The person in the position will be illuminated by a vertical illuminance of more than 0.5 lx, so that the person located anywhere in the lane 1 can also perceive the external characteristics of the person. The only important clue to the appearance is the face. The average height of Japanese people from the face on the road surface is about 1.5xη, so the following description considers the height position of the required vertical illumination as the height of h5m on the road. This is point 4 'in the first step. In addition, according to the configuration shown in FIG. 1, the angle (vertical angle) formed by connecting the direction I−6 ′ of the lighting device 3 a and the opposite middle point 4 and the direction directly below the lighting device 3 a is about 76 degrees, and The angle 181 (vertical angle) formed by the luminaire 3a and the point 181 of the height above the middle point 4 opposite to the opposite middle point 4 is about 1-5m. The angle (vertical angle) formed by the direct direction of the luminaire 3a is about 81 degrees. If the luminosity is calculated under the setting conditions of the lighting fixtures 3a and 3b of the first 囷, then the point 4 with a height of 1.5m above the opposite intermediate point 4 is to obtain the vertical surface illuminance Εν facing the surface of the lighting fixture in the direction 5 = 〇 · 5 lx The required light intensity from the lighting fixture 3a in the direction (also expressed as 1) π, if the estimated conservative rate (compensating lighting fixtures; -18-The paper size of the table applies the Chinese National Standard (CNS) A4 specification (210 * 297 mm) ---------—— Installation · 丨-(Please read the Φ-face's precautions first ¥ Fill this Page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs-If I if * A7 B7 451 042 V.

In the above calculation, L represents the vertical plane from the lighting device 3a of the light source to the calculation object (that is, the point with a height of about 1.5m above the opposite intermediate point 4, and facing the lighting device 3a in the direction 5 The distance Θ is the incident angle β of the light irradiated from the lighting device 3 a toward the vertical plane on the vertical plane. On the other hand, regarding the road illuminance, the road illuminance (horizontal plane illuminance) near the opposite middle point 4 , Which is the total of the illuminance according to the Ming appliance 3 a and the illuminance according to the Ming appliance 3 b. Therefore, if the illuminance of the pavement near the opposite middle point 4 is to reach Eh = 0.5 lx or more (that is, the minimum illuminance of the pavement 値 Ehmin = 0,5), the illuminance in the direction of 176 by the lighting device 3a can be determined ( The same calculation result is shown in the following general formula: I76 = [(Ehmin / 2) K2) / (M · cos ^ ') = [(0.5 / 2) x {4.52 + 52 + (35/2) 2}] / [0.72 x cos76 °] = 504 Set I76 = about 504cd or more. Among them, K represents the distance from the lighting fixture 3a of the light source to the opposite intermediate point 4, and Θ 'represents the incident angle of the light emitted from the lighting fixture 3a toward the opposite intermediate point 4 on the horizontal plane (road surface).

Description of the invention (20) In terms of the configuration of the roadway lighting device 3 of the seventh row and the configuration of the roadway lighting device 33 of FIG. 8, the single lamp holder type fluorescent lamp 6 is a light-emitting tube. The long axes of 6a and 6b are arranged along the roadway transverse axis direction 32 and parallel to the transparent portions 9a on both sides of the translucent lampshade 9, and the light emitting tubes 6a and 6b are arranged relative to the reflecting plate 7. Set up and down direction. Therefore, most of the light beam can be radiated to the side by the single-lamp fluorescent lamp 6, so that the amount of light emitted in the up and down direction is reduced (about 1/2 of the side light beam). At 7 «, the light path of the light emitted by the lighting device 3 will be described as follows. The light 9a emitted from the single lamp holder type fluorescent lamp 6 obliquely downward and laterally is transparent through the transparent light cover 9 Portion 9a travels to a distant pavement in the long axis direction 31 of the roadway. In contrast, light 9b radiated downward by a single lamp-type fluorescent lamp 6, When passing through the prism cutting portion 9 b of the light-transmitting lamp army 9, it is refracted by traveling farther into the roadway long axis direction 31 than directly below the lighting fixture 3. In addition, a single lamp holder type fluorescent lamp 6 The light 8 radiating obliquely upwards and upwards, the specular reflection surface 8a of the reflecting plate 7 receives the front and back sides of the obliquely lower side, passes through the transparent portion 9a of the light-transmitting lamp army 9 and the length of the roadway is The axis direction 31 travels farther than the light 9a and 9b.

Description of the Invention (21) A plurality of members with mutually different refractive indices , Or set a proper refractive index slope in a single member 'or other treatments. Furthermore, it is assumed that the vertical angle of the optical center of the fluorescent lamp 6 which is perpendicular to the long axis direction of the lamp tube 6 (the cross-section drawing direction 32 in FIG. 7) and does not include the section in the long axis direction is a vertical angle of zero degrees At this time, if the transparent portion 9a of the light-transmitting lampshade 9 is a plane for the areas where the left and right vertical angles of the optical center of the fluorescent lamp 6 are 45 degrees or more, the plane is obliquely incident due to the radiation from the lamp 6 The incident angle of light will become shallower, so that such an incident chirp will be totally reflected on the surface. Therefore, even if the flat surface (that is, the transparent portion 9a of the light-transmitting lampshade 9 is transparent, the actually transmitted light will be reduced. In contrast to this, the roadway lighting device 3 or 33 of the present invention shown in FIG. 7 or 8) The constitution 'is provided in the transparent portion 9a of the translucent lamp sheet 9 with a curved surface portion 9d in the range of 45 degrees or more and 60 degrees or less from the vertical angle of the left and right optical centers of the fluorescent lamp 6. Therefore, since the fluorescent lamp 9 6 The incident angle of the radiated light becomes deeper, which can avoid the problem of total reflection. In addition, the part of the translucent lampshade 9 that exceeds 60 degrees of the vertical angle, because the incident angle of the light is deep, it is not necessary to make a curved surface. The larger the width of the reflecting plate 7 (the width measured in the direction 31 in Figures 7 and 8) measured along the direction perpendicular to the light emitting tubes 6a and 6b of the lamp tube 6, the larger the self-fluorescent lamp. 6 The ratio of the light emitted upward from the specular reflecting surface 8a to the obliquely lower side makes the lighting efficiency increase. However, if the width of such a reflecting plate 7 is increased, the lamp tube storage portion ι〇3 The increased internal volume reduces the thermal insulation of fluorescent lamp 6. ， Fluorescent lamp 6 has the characteristics of a significant decrease in lamp efficiency when the ambient temperature decreases. Therefore, the paper size is applicable to the Chinese National Standard (CNS) A4 wash case (210X297 mm) (please read the note f on the back first) (Fill in this page again.)

Description of the invention (22) The internal volume of the lamp housing 106 needs to be made as small as possible. P-51 Another On the other hand, in recent years, the negative impact of outdoor lighting on residential environment or astronomical observations (obstacle light) has caused problems. Therefore, in Japan, government agencies have established a law on light pollution standards. Among them, in general urban areas, the upper beam should be regulated. It is 15% or less of the full beam. This means that more than 85% of the light supplied from the light-emitting tubes 6 a and 6 b must be radiated downward. The light-emitting tubes 6 a and 6b are irradiated in the light of 360 degrees The 180-degree side (full beam ratio is 50%) belongs to the lower beam. Therefore, if you want to achieve the above, the light above 126 degrees (the full-beam ratio is 35%) in the upper 180 degrees should be reflected by the reflective plate 7 Shine down. To do this, you must Geometrical conditions such as the diameter of the light-emitting tubes 6a and 6b, the distance between the light-emitting tubes 6a and 6b and the reflective plate, and the width of the reflective plate 7 are set within a certain range. Figure 9 shows assuming that the diameter of the light-emitting tubes 6a and 6b (only the uppermost light-emitting tube 6a is shown in Figure 9) is 28 mm in diameter, and the distance between the top of the light-emitting tube 6a and the reflective surface 7 is 2 mm to 3 Omm In this case, the relationship between the width W of the reflection plate 7 and the vertical line λ of the line connecting the end of the reflection plate 7 from the center of the light-emitting tube 6a. From the figure 9 'In the case of the light-emitting tube diameter of 2 8ππη In order to reflect the light converted from the above 126 degrees into the vertical angle of the vertical angle α = 63 degrees or more, it is necessary to set the width W of the reflecting plate 7 to about 63 mm to 175 mm. That is to say, the reflecting plate 7 When the width is set to be more than twice or less than seven times the diameter of the light emitting tube, the upper beam can make up less than 15% of the total beam. In addition, in the measurement of the result shown in FIG. 9 above, the minimum distance between the uppermost surface of the light-emitting tube 6a and the reflective surface 7 is set to 2 mm, which is due to the lamp (issue -25- Standard (CNS) A4 specification (210 x 297 mm) Du Yin, the Consumer Procurement Co-operation of the Central Procurement Bureau of the Ministry of Economic Affairs *. 4: Revised page of the Chinese manual for patent applications (June 1990) V. Description of the invention (23) Light (Pipe) When the lamp is in contact with the reflecting surface, a phenomenon such as a reduction in lamp performance due to vibration may occur, so it is set as a distance that does not cause such an adverse effect. The structure of Fig. 7 is provided in the light-transmitting lampshade 9 and is provided with a cut-out portion 9b within a range of 45 degrees from the left and right vertical angles to the optical center of the labor lamp 6 respectively. In addition, as shown in FIG. 8, the prism cutting portion 9 b is provided on the side portion of the light-transmitting lamp cover 9 above the center position of the light pipe 6 b located at the lower position. The prism cutting portion 9 c refracts the light traveling in the upward space and causes it to travel on the road. This can improve the lighting efficiency on the road surface and reduce the obstacle light to the surroundings. The solid line C in (6) (a) indicates the light distribution of the A section obtained by the roadway lighting device 3 of the present invention having the structure shown in FIG. 7. The dotted line B indicates the light distribution of the A section obtained when the same diffusive flat plate is used as a reflection plate in the past. The single lamp holder type labor light 6 and the transparent light cover 7 are still the same as those in FIG. 7 . In addition, the solid line A is the light distribution of the section A that can be obtained by the conventional roadway lighting equipment described above with reference to FIG. 13. From the result of FIG. 6 (a), it is known that the light distribution of the roadway lighting fixture 3 according to this embodiment passes through the center of the roadway lighting fixture 3 and is perpendicular to the roadway surface at the time of installation. The light distribution shape of the A section with a parallel edge is a symmetrical batwing shape with respect to the B section perpendicular to the side edge of the roadway. As a result, compared with the former, the light distribution in the vicinity of the middle (vertical angle of about 75 to 80 degrees) of the adjacent lighting poles is increased. In contrast, the light distribution near the bottom (0 ~ 30 degrees) is reduced. However, the illuminance near the bottom is originally high, so there will be no reduction. -26 (CNS > A4 wash case (210x297 mm) (please read the note on the back before filling in this page) Order 45104 2 A7 ___B7________ 5. Description of the invention (24) Negative effects. On the contrary, the present invention is uniform due to uniformity of illumination (Minimum illuminance / average illuminance) will satisfy the aforementioned predetermined threshold, so that the effect of darkness will not be felt psychologically. Fig. 10 is a calculation result of the illuminance distribution of the road surface obtained by the roadway lighting method of the present invention expressed in a mode. Specifically, in accordance with the arrangement mode of the roadway lighting appliances described with reference to the first circle, the roadway according to the present invention is installed at a position of 4.5m in height at a height of 4.5m in a roadway with a width of about 5m at a distance of 35m. Under the state of lighting fixtures (in the case of roadway lighting fixtures 3 in Figure 7) (assuming that the light beam of roadway lighting fixtures 3 = 3000 lm), assuming the conservative rate of the lights = 0.72, calculate the Illumination Figure 10 shows the distribution of the illuminance when the road surface is viewed from above, calculated from the above, using the isoline. In addition, the installation position of the lighting equipment in the middle of the roadway is equivalent to the corners on the lower right and lower left of the road. The figure also shows the direction of the long axis of the roadway 31 and the direction of the transverse axis 32 of the roadway. From the 1st 10th, it can be seen that according to the present invention, the average road illumination = 3.1 lx, the minimum illumination 0.9 lx 'maximum illumination = 8 · 8 lx, the uniformity of the road surface illumination Gl = 0.29 and G2 = 0.1, which meets all the above-mentioned better standards of the road surface illumination level or the uniformity of the road illumination.

Also in Figs. 7 and 8, the specular reflection surface 8a of the reflection surface 7 has a shape protruding toward the lamp tube storage portion 106 (fluorescent lamp 6), but the specular reflection surface is- 27- This paper size applies to China National Standard (CNS) A4 (210 X 297 (Centi) 451 04 2 A7 ___B7_ 5. Explanation of the invention (25) (reflective plate) may also have a flat plate or other shapes. Specifically, the 12th circle (a) ~ (b) indicates the specular reflection of the present invention Examples of the combination of the shape of the surface (reflection plate) and the lamp. Also shown in Figures 11 (a) and (c) are examples of the combination of the reflecting surface (reflection plate) and the lamp of the prior art. Figure 11 (b) ) And (d) show the general light distributions that can be obtained by using the constitutions of Figure 11 (a) and (c). First, according to the prior art, the first circle (a) is the diffusion on the plate. The reflecting surface 8x is composed of a single light-emitting tube 11. However, in this case, as shown in Section 11 (b), an approximately elliptical light distribution is formed, making it almost impossible to reflect light to a distance. The diffusive reflection surface mentioned above refers to the surface which reflects the incident light in all directions. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. As for section (c), a single light-emitting tube 11 is combined on a reflecting surface curved so that the opposite side of the light-emitting tube 11 becomes convex. In this case, as shown in Section 11 (d), the light is distributed by irradiating the reflected light in a direction opposite to the incident light so that the light can reach farther than directly below. However, this shape is the light distribution of general road lighting equipment and is not suitable for roadway lighting equipment. The reason is that the installation interval of the roadway lighting fixtures is 6 to 9 times the installation height, but the interval of the road lighting fixtures is 3 to 4 times the installation height. The vertical angle is 50 ~ 65 degrees, which is different from street lighting appliances. In contrast, FIG. 12 (a) of the modified example of the embodiment of the present invention is flat, but is not a diffuse reflection surface, but a reflection surface (mirror reflection surface) 8b forming a mirror surface is combined into a single fluorescent tube 11 Into a composition. Among them, -28- This paper size is in accordance with Chinese National Standard (CNS) A4 (210 * 297 mm) 45104 2 as B7. V. Description of the invention (26) The so-called specular reflection surface means that the incident light can be directed to a certain direction. The surface whose direction is strongly reflected. In this case, it is possible to reflect light farther than the configuration of the flat plate-shaped diffuse reflection plate 8x using the conventional technology shown in FIG. 11 (a). With this configuration, the reflecting surface 8b (reflection plate) does not need to be provided with a curved portion (convex portion), and therefore has the advantage of being the thinnest type.

Figure 12 (b) shows a single lamp holder type fluorescent lamp 6 provided by overlapping two light-emitting tubes 6a and 6b in an up-down direction, and a mirror surface that is convex toward one side of the fluorescent lamp 6 as a whole. The reflection plate 8c is a combination. According to this structure, as compared with the case of using the flat specular reflection plate 8b as shown in Fig. 12 (a), the light can be reflected far away, so it has the advantage of improving the uniformity of the illuminance on the road. If the fluorescent lamps 6 having a plurality of light-emitting tubes 6a and 6b are combined into a flat mirror-like reflecting surface 8b as shown in FIG. 12 (a), the light emitted from the upper-stage light-emitting tube 6a directly above will be reflected from the reflecting surface 8b. The regular reflection is absorbed by the upper-stage light-emitting tube 6a. However, if it is constituted according to 121 (b), the specular reflection surface 8c has a V-shaped overall convex shape toward the fluorescent lamp 6. Therefore, from the upper stage, The light emitted from the light-emitting tube 6a directed upwards will hardly return to the light-emitting tube 6a after being reflected on the specular reflection surface 8c, and will be reflected to the downward direction. Therefore, it is also possible to improve light emission efficiency from this point.
