Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a traffic signal light used for a traffic signal installed at an intersection such as a crossroad or a T-shaped intersection.

[0002]

[Prior art]

 The traffic lights that have been used up to now are of the three-light type that have three types of traffic lights of red, yellow, and blue, and are supported on columns by arranging them in one horizontal row or one vertical row in the housing. . Each signal light has a reflecting mirror behind the light source and a color lens that transmits red, yellow, or blue light on the front surface.Three signals of red, yellow, and blue are provided. Of the lamps, only the light source of the signal lamp selected by the control device is energized and transmits red, yellow, or blue light, which is determined by the color lens it has, and, needless to say, the signal lamp is set to that color. It will be lit. In this way, the control device selectively turns on one of the signal lights at an appropriate time and order to organize traffic.

Since the traffic signal currently used has the above-mentioned configuration, particularly when direct sunlight enters the signal lights from the front, especially when the position of the sun in the morning and evening is low. Not only in the signal lamps that are lit but also in the signal lamps that are not lit, the incident light is reflected by the reflecting mirror behind the light source, and this reflected light is emitted through the color lens. Therefore, the signal lights also appear to be lit in the corresponding colors, and in the end, all the signal lights appear to be lit at the same time. However, it may be difficult to distinguish which signal light is on, and it may not work as a traffic signal.

In addition, the current traffic signal is in a disappearing state due to the strong light when the sun is positioned behind the signal light, and it is difficult to determine which one is lit. It can be almost lost.

Further, needless to say, the current traffic signal is of a three-light type and is relatively large in size. Therefore, it is easily affected by the wind and sways due to the wind on a strong wind day. There are also problems such as being difficult to see.

[0006]

[Problems to be solved by the device]

 In the present invention, however, the above problems are solved, and even when direct sunlight enters the signal lamp from the front when the position of the sun in the morning and evening is low, it lights in any color. It can be clearly discerned whether or not there is a signal light, even if sunlight is shining from behind, and the phenomenon of loss of the signal light does not easily occur, and it can be constructed in a small size to reduce the influence of the wind and The problem to be solved is to provide a traffic signal light that does not easily swing.

[0007]

[Means for Solving the Problems]

 The gist of one configuration of the present invention is that a machine box provided with lenses in front and rear openings, a light source arranged in an intermediate portion between the front and rear lenses of the machine box, and the light source located in the central portion thereof. A pair of color filters that pass red light, a pair of color filters that pass blue light, and a pair of yellow light that form two parallel surfaces. The filter section consisting of a pair of color filters to be passed, and the filter section are rotated by 60 degrees about the central axis of the filter section every set time, and each of the pair of color filters is set to the front and rear lenses. And a light source for rotating the light source, which is located between the light source and the light source.

The hexagonal tubular filter unit is rotated by 60 degrees for each set time so that each of the pair of color filters is positioned on a straight line connecting the front and rear lenses and the light source. It is not inconvenient to arrange in any way as long as it can be arranged. It is convenient to arrange the filter part so that its central axis is oriented vertically or horizontally so that the machine box can be configured without being unduly large.

The rotation driving means is free to use any means as long as it can rotate the hexagonal tubular filter portion about the central axis by 60 degrees as described above. Can be used for. Therefore, it is suitable to use an electric motor as the rotation driving means because the control is easy. Although the control means can be configured in various ways, in response to the output of the existing control device which is output at every set time, the hexagonal tubular filter section is rotated by 60 degrees around the central axis as described above. It is configured such that the rotation driving means can be controlled so as to rotate so that the required color filters are positioned between the lenses on both sides and the light source. Alternatively, the existing control device itself is modified to operate in that way.

As the front and rear lenses of the machine case, transparent ones which are generally used in the past can be used. As the light source, a light bulb which is generally used conventionally can be used. A light bulb that emits white light that includes red, yellow, and blue equally is suitable. Further, as the one-to-three types of color filters forming the hexagonal tubular filter section, color filters which are generally used in the past can be adopted. For example, a plate-shaped color filter can be formed into a hexagonal cylinder while being supported by a frame member. Both ends of the hexagonal cylinder are closed by end plates, a rotary shaft is projected from the both end plates along a center line, and the ends of the rotary shaft are rotatably supported by a machine box or a bracket arranged in the machine box. The rotation drive means is connected to one of the rotation shafts through a speed reducer if necessary.

The gist of the second configuration of the present invention is a machine box having lenses at front and rear openings, and a light source arranged in the middle of the lenses at the front and rear of the machine box, which are red, blue and yellow. The traffic signal lamp is configured by: a light source capable of selectively emitting the above light and a switching means for switching the emission color of the light source for each set time, and the above problems can be solved by this.

Any light source can be adopted as the light source as long as it can selectively emit red, blue, and yellow light. For example, adopting a light source that has three light emitting parts that can generate light of each color, or configure one light source that has three individual light sources that can generate the above three types of light. It may be done.

As the front and rear lenses of the machine case, transparent lenses which are generally used in the past can be used. Further, as the switching means for switching the emission color of the light source for each set time, a switch generally used in general can be adopted.

[Action]

 Since the present invention is configured as described above, if it is installed and used at a required intersection or the like in place of a conventional communication signal light, the following effects can be obtained and various advantages can be obtained. .

First, one aspect of the present invention will be described as follows. At each set time, the hexagonal cylindrical filter section is rotated by the rotation driving means, and, for example, a pair of red color filters are located between the light source and the lens, and the signal lamp lights up in red. Will be done. When the required time has elapsed and the rotation drive means rotates, the filter section rotates, and a pair of blue color filters are now positioned between the light source and the lens, and the signal light turns blue. It will be lit. Then, after the required fixed time has elapsed, the rotation driving means is also driven to rotate, whereby the filter portion is rotated, and a pair of yellow color filters are located between the light source and the lens, respectively. The signal light will be illuminated in yellow. Next, after a lapse of a certain short time, the rotation driving means rotates to rotate the filter section, and as described above, the pair of red color filters are respectively located between the light source and the lens, and Will illuminate red.

As described above, the red, blue, and yellow lighting cycles are repeated, and although it is one signal light, it is possible to emit three kinds of signals of red, blue, and yellow as in the conventional case. .

The traffic signal light according to one aspect of the present invention has the above-described structure and operates as described above. Therefore, one traffic light can first constitute a traffic light, and one traffic light can operate in the same manner as the conventional traffic light. Needless to say, since it can be configured with one signal light, the signal can be manufactured in a small size, and problems such as rocking by the wind can be suppressed.

Further, when direct sunlight enters the signal lamp from the front when the position of the sun is low in the morning and evening, the incident light only passes through the lens and the filter portion and travels backward. , It is unlikely that it will look like a color other than the color filter selected at that time. Therefore, the color can be easily discriminated and the function as a traffic light can be accurately achieved.

Similarly, when the position of the sun in the morning and evening is low, even when the sun is positioned behind the signal light, the strong light is reflected by the lens behind, the pair of color filters in the filter section, and It will pass through the front lens and enter the human eye, and only stronger light will be transmitted, and the lighting color will not change. However, since the light coming around the traffic lights is often stronger, it may be a little hard to see, but it is likely that the disappearance phenomenon will occur due to the sunlight from behind like the conventional traffic lights. Therefore, it does not lose its function as a traffic light.

The second aspect of the present invention will be described below. The light emission color of the light source is switched by the switching means at every set time, for example, the red light is emitted first, and after the elapse of a certain time, the switching means is switched to emit the blue light. Then, after a lapse of a predetermined time, the yellow light is emitted by the switching means. Further, after a certain period of time has elapsed, the switching means switches the light and red light is emitted again.

As described above, the red, blue, and yellow lighting cycles are repeated, and although it is one signal lamp, it is possible to emit three kinds of signals of red, blue, and yellow as in the conventional case. .

The second traffic light of the present invention is constructed as described above and operates as described above. Therefore, like the first traffic light of the present invention, first, one traffic light is replaced by the conventional three-light type traffic light. It is needless to say that the same operation as that of the traffic signal can be performed, and since the traffic signal can be configured by one traffic light, it can be manufactured in a small size and the problem of rocking by the wind can be suppressed.

Further, even when direct sunlight enters the signal lamp from the front when the position of the sun is low in the morning and evening, the incident light only passes through the lens and travels rearward, and at that time. It cannot be seen as a color other than the selected emission color. Therefore, it is easy to distinguish the colors, and the function as a traffic light can be accurately achieved.

Similarly, when the position of the sun in the morning and evening is low, even if the sun is positioned behind the signal light, the strong light passes through the lens in the back and the lens in the front, and is emitted by the human. It is incident on the eye of the eye, and only stronger light is transmitted, and the lighting color does not change. However, the light coming from around the traffic lights is often stronger, so it may be a little hard to see, but like the conventional communication lights, there is a phenomenon of disappearance due to sunlight from behind. Since it does not happen, it does not lose its function as a traffic light.

It is located between 1 and 1, and the signal light will be lit in yellow. Next, after a lapse of a preset short time, the electric motor 5 is rotated to rotate the filter unit 4, and as described above, the pair of red color filters 4a and 4a are respectively connected to the light bulb 3 and the light bulb 3. It is located between the lenses 1 and 1, and the signal light will turn on red again.

The above red, blue, and yellow lighting cycle is repeated, and although the traffic light is composed of one signal light, it is possible to emit three kinds of signals of red, blue, and yellow as in the conventional case. Becomes

Next, a second embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 4 to 6, the traffic signal light of this embodiment is arranged in a machine box 12 having lenses 11 and 11 at front and rear openings and an intermediate part between the lenses 11 and 11 before and after the machine box 12.

The machine box 12 has a substantially spherical shape. A support ring 16 is arranged in the center of the machine box 12, and three arms 16 a, 16 a, 16 a extending toward the center of the support ring 16 are provided at the tips of the three arms. Each of the light bulbs 13a, 13b, 13c is supported. As shown in FIGS. 4 and 5, the support ring 16 is fixed in parallel with the lenses 11, 11 by four support rods 16b, 16b. It goes without saying that the outer ends of the four support rods 16b, 16b ... Are fixed to the machine case 12. As the lenses 11 and 11, transparent lenses that are generally used conventionally are adopted.

The change-over switch is selectively changed over to supply power to any of the three light bulbs 13a, 13b and 13c which emit red, blue and yellow light according to a signal from an existing control device.

The above lighting cycle of red, blue, and yellow is repeated, and it is possible to emit three kinds of signals of red, blue, and yellow in the same manner as the signal lamps of the conventional three lamps, though it is one signal lamp.

[0038]

[Effect of device]

 Since the traffic signal light of the present invention is constructed and operates as described above, it goes without saying that it can function as a signal light similar to that performed by the conventional three signal lights. Since the traffic light can constitute the traffic light, it can be manufactured in a small size, and problems such as rocking by the wind can be suppressed.

Even when direct sunlight is incident on the signal lamp from the front when the position of the sun is low in the morning and evening, in the case of the present invention, the incident light passes through the lens and the filter unit and goes backward. It is only transparent, and it cannot be seen as a color other than the color filter selected at that time. Therefore, it is easy to distinguish the colors, and the function as a traffic light can be accurately achieved.

At the same time, in the case of the second aspect of the present invention, the incident light only passes through the lens and travels rearward, and a color other than the emission color selected at that time. Can never be seen in. Therefore, the color can be easily discriminated and the function as a traffic light can be accurately achieved.

However, since the light coming from around the traffic lights is often stronger, it may be a little difficult to see, but it is likely that the disappearance phenomenon will occur due to the sunlight from behind like the conventional traffic lights. Therefore, it does not lose its function as a traffic light.

Similarly, when the position of the sun in the morning and evening is low, in the case of the second aspect of the present invention, even when the sun is positioned behind the signal light, the strong light is reflected by the lens behind and It will pass through the front lens and enter the human eye, and only stronger light will be transmitted, and the lighting color will not change. However, the light coming from the surroundings of the signal lights will be stronger in most cases, so it may be a little difficult to see. Therefore, it does not lose its function as a traffic light.
