Description

  The present invention reduces the reflection as much as possible by the non-reflective plate without colored glass in the sunlight reflected on the traffic signal, and the display is made with colored optical fibers on the non-reflective plate set with the inclination angle, so that the driver can reliably The present invention relates to a non-reflective traffic signal device that recognizes traffic signals and integrates traffic signals in the direction opposite to the traveling direction to reduce costs.

  Conventionally, traffic lights at intersections are separated from each other in the same direction and in the opposite direction, but the signal bodies are separated and the wiring is externally attached. It was. In addition, in order to improve the luminous intensity, the lamp of the light source has become heavy, and the weight has been increased including the colored glass.

  This colored glass is used in three colors of red, blue, and yellow, but the surface has an arc shape to prevent reflection of sunlight. However, the reflectance is high in the morning and evening, and the signal display may not be confirmed temporarily. In reality, it is necessary to gradually go to a place where the signal display can be seen while checking the operation status of the surrounding cars and the traffic lights on the left and right. is there. In addition, a sunshade is set on the display lamp, but this is also not effective when the sun rises or at sunset.

  Therefore, recently, a traffic signal device using a plurality of LEDs for position display has been developed, and unlike the conventional lamp specification, it is easy to see, but the above problem still remains.

  The present invention does not combine traffic signals with the same display in the direction opposite to the direction of travel in back-to-back configuration, but as an integrated compact design, while reducing costs and reducing reflection on the display surface by sunlight. However, it ensures that the driver can confirm the traffic signal display. The same applies to a single traffic signal.

Means to solve the problem

  The non-reflective integrated traffic signal box of the present invention is divided into three parts, with a red display on the upper left and right, a yellow display on the left and right in the middle, and a blue display on the lower left and right. A plurality of optical fiber cables extending from the right and left are uniformly installed on the non-reflective display unit, and the non-reflective plate is inclined.

  At the same time, the outer peripheral fiber of the display circle is projected to make it easy not only to check the display in the forward direction but also from the left and right.

Effect of device

  According to the present invention, by combining the same display separation type traffic signal lights in the same box, six light sources required can be reduced to three half light sources, and the production material cost and the installation cost are greatly reduced. Since a plurality of optical fibers are used, the traffic signal body can be made compact, and the display performance can be improved simply.

  The optical fiber itself emits red, yellow, and blue light and extends from the light source in the center to the left and right. The end of the optical fiber is joined to a black non-reflective part, and each of the color displays is plural. Because there is, it becomes clear. In addition, the non-reflective part that is a joint part is inclined so that the direction of the light of the optical fiber is directed to the driver, thereby further facilitating the display confirmation.

  Further, by making the outer peripheral circular optical fiber of the display unit protrude from the non-reflecting plate, it is possible to check the display in the horizontal direction or the oblique direction.

  The non-reflective display part is made of a material that does not reflect light, and can be made to be black, so that the reflection of sunlight can be reduced. However, by adding an inclination angle, the reflected light of sunlight cannot reach the eyes. . Thereby, the display confirmation of the traffic signal is further improved.

  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view of the present invention and a side view thereof, in which the depth dimension of a traffic light box 10 in which a traffic light in the direction opposite to the traveling direction is integrated is shortened as much as possible to make it compact. Since this traffic light box 10 is for assembling internal wiring and the like in the state of FIG. (A), it is to create the traffic light box 10 with the front view of FIG. In the state where the internal wiring and the like are completed, a lid is applied from above to take measures against wind and rain.

  As for the inside of the traffic light box 10, it is red, yellow, and blue from the top in accordance with the traffic light, but it can be changed. Therefore, the inside of the traffic light box 10 is divided into three sections. This three-stage internal structure is the same in other structures except that each color is different.

  At the left and right ends of the traffic light box 10, the non-reflective plate 13 including the non-reflective display unit 3 is installed within a downward inclination angle of 60 to 75 degrees. The non-reflecting plate 13 is preferably a film that does not reflect light, but if it is a paint, it is a matte material or the like. Materials that combine particles such as concrete and bricks are those that do not bounce the dazzle of sunlight, and in any case prevent reflection of sunlight, are heat resistant, and include ceramics and ores. Weather resistant materials that can withstand sunlight, wind and rain, etc. are preferred. If the color is black, the color and discrimination of the optical fiber can be improved.

  Inside the non-reflecting plate 13, a display part outer circumference circular optical fiber 11 having the same outer diameter as the display part of the traffic signal device and a hole in which a plurality of display part outer circumference inner optical fibers 12 are installed are also bored inside. The outer diameter of the optical fiber is about 10 mm, but it is easy to check the display by setting the outer diameter to at least 5 mm. Further, as shown in FIG. 2A, the holes are uniformly opened along the outer periphery circle of the display unit, and the outer periphery circle is also uniformly formed, but the interval ratio is larger than the interval between the outer periphery circles. It may be large.

  FIG. 2B is a diagram in which each optical fiber is configured on the non-reflecting plate 13, but the display portion outer periphery circular light fire bar 11 is projected from the non-reflecting plate 13 and installed. When the traffic signal display unit of the present invention is seen in front of the traveling direction, all the traffic signal display units can be confirmed satisfactorily, but the display confirmation of the traffic signal on the left and right is made easier to see. The projection size of the outer circumference circle is preferably as small as possible. However, in consideration of display confirmation, a projection of at least about 5 mm is required.

  With the horizontal direction as a reference, a red light source 4 is installed at the center from the top, a yellow light source 5 is installed at the middle, a blue light source 6 is installed at the bottom, and then a plurality of red optical fibers 7, yellow optical fibers 8, and blue optical fibers 9 are extended to the left and right. The non-reflecting plate 13 is installed.

  Although it is installation of each optical fiber to the non-reflecting plate 13, it is a point that it inserts and the circumference | surroundings use an adhesive material so that there is no rain leak. Also, it is to block rain and the like from entering from the end of each optical fiber. In other words, the optical fiber is preferably end-treated from the beginning, and if the surface is slightly concave, the light is diffused a little, thereby filling the gap of the display unit, One surface display like a conventional colored glass is made possible with the light of the optical fiber. Further, since the light is concentrated and the degree of advancement is large, the certainty of display is improved.

  On the upper part of the outer peripheral circle of the display part of the non-reflecting plate, the sunshade 2 provided in the conventional traffic signal is used as the sunlight reflection prevention from above. It is desirable to install in.

  FIG. 3 shows the state when the driver reflects light from sunlight and the light of the optical fiber of the traffic signal device of the present invention is reflected by a non-reflecting plate. In other words, the non-reflective plate prevents the reflection of the sun, but here, if it is reflected, it will be verified in what state angle it enters the driver's eyes 16.

  The sunlight incident angle A14a of the sun A can be said to be in a state around 7 o'clock in the morning in summer or around 5 o'clock in the evening. The sunshade 2 is passed and begins to hit the non-reflecting plate 13, but the reflected light A14b reflects the sunlight toward the front because the non-reflecting plate 13 is inclined. In the evening, the sun gradually tilts, and in the sun B, it becomes almost parallel to the horizon. As shown in FIG. 3, the sunlight incident angle B15a is not reflected to the driver's eyes 16 because the non-reflecting plate 13 is inclined downward even at an incident angle parallel to the horizon, that is, 0 degrees. It is. Thus, since the sun cannot enter from below the horizon, sunlight is not reflected on the driver's eyes 16 by tilting the reflector, in other words, the conventional traffic signal Thus, the state where the reflection on the display unit enters the driver's eyes 16 and the display confirmation becomes difficult disappears.

  In addition to this, the location where sunlight reflects is provided with a non-reflecting plate 13 as in the present invention, so that a double reflection measure can be taken. Furthermore, it can be said that the traffic signal display can be surely confirmed by installing an optical fiber having good transmittance.

(A) is an enlarged view of the display unit shown in the side view of FIG. 1, and (B) is an enlarged view of the display unit outer circular optical fiber and the display unit outer circular optical fiber installed on the non-reflecting plate. is there.
