Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedestrian auxiliary signal light and a pedestrian auxiliary signal light device using the same.

[0002]

2. Description of the Related Art Pedestrian signal lights are installed near intersections and crosswalks at points other than intersections. A conventional pedestrian signal light is supported by a support pole or the like standing upright on the roadside and installed on the ground. This pedestrian traffic light on the ground generally has a structure in which a red light emitting portion and a blue light emitting portion that are partitioned from each other are arranged in parallel.

However, pedestrian traffic lights on the ground are
Visibility is not always good because it is installed on the opposite side of the pedestrian crossing, not on the front side of the pedestrian crossing.

Therefore, conventionally, a red light emitting lamp which is buried in the ground along a pedestrian stop line on a pedestrian crossing and which emits light in conjunction with a pedestrian signal light on the ground is an auxiliary signal light for pedestrians. Was proposed as (Shokaisho 62-11769
No. 9). This pedestrian auxiliary signal light has a configuration in which a plurality of illumination lights are arranged one-dimensionally (in a line) in one housing having a length that extends over the entire length of the pedestrian stop line.

According to this conventional pedestrian auxiliary signal light,
When crossing is prohibited, red light is emitted at the foot of the pedestrian along the stop line, which improves visibility and makes people feel closer to stopping, which further improves traffic safety.

[0006]

However, since the conventional pedestrian auxiliary signal light is composed of only the red light emitting lamp, it is possible to assist the pedestrian signal light on the ground when stopping (prohibiting crossing). However, it is inconvenient for pedestrians to check the progress (crossing) without looking at the pedestrian signal lights on the ground. Especially for elderly people with bent waists and short children, it is difficult to see the pedestrian signal lights on the ground, so it is extremely important to look at the pedestrian signal lights on the ground and make sure that you can cross the pedestrian crossing. It's inconvenient.

The present invention has been made in view of the above circumstances, and can completely assist the function of a pedestrian signal light on the ground, thus improving traffic safety and facilitating the confirmation of pedestrian signals. It is an object of the present invention to provide an pedestrian auxiliary signal lamp that can be performed at low cost.

[0008]

In order to solve the above-mentioned problems, the pedestrian auxiliary signal light according to the first aspect of the present invention comprises:
It is a pedestrian auxiliary signal light that is buried in the ground near the pedestrian stop position on the pedestrian crossing and can emit multiple colors in conjunction with the pedestrian signal light on the ground. It is two-dimensionally mixed in one housing. It is provided with a plurality of sets of light emitters arranged and having mutually different emission colors. In the present specification, the pedestrian signal light on the ground includes not only a pedestrian-dedicated signal light but also a vehicle-purpose signal light that can be seen when a pedestrian crosses a pedestrian crossing. .

According to the pedestrian auxiliary signal light of the first aspect, it is buried in the ground near the pedestrian stop position on the pedestrian crossing and can emit light in a plurality of colors in conjunction with the ground pedestrian signal light. It emits light at the foot of pedestrians and shows the same contents as the signal lights for pedestrians on the ground. Therefore,
The function of the pedestrian traffic light on the ground can be fully assisted, and not only can traffic safety be improved, but it is also possible to check the signal regarding the progress (crossing) by just looking at your feet. Therefore, the pedestrian can confirm the signal, and it is extremely effective especially for an old man with a bent waist or a short child.

In order to completely assist the function of a pedestrian signal light on the ground, when realizing a pedestrian auxiliary signal light that is embedded in the ground and can emit light of multiple colors, this pedestrian auxiliary signal light also has Similar to the pedestrian auxiliary signal light, it is conceivable to partition the light emitting unit for each color. However, in this case, the sum of the areas of the light emitting portions of the respective colors is the area of the entire light emitting portion, so that the size must be increased and the cost is inevitably increased. In addition, if the size is increased, the effect will be great if the height of the ground partially changes, and it is necessary to secure sufficiently strong strength to prevent damage due to it, which also increases costs. I cannot escape. On the other hand, in the pedestrian auxiliary signal light according to the first aspect, since a plurality of sets of light emitters having mutually different emission colors are arranged in a two-dimensional manner, the light emitting portions of the respective colors are integrated, The area of the entire light emitting portion can be made considerably smaller than that in the case of dividing the light emitting portion for each color. Therefore,
According to the first aspect, the size can be reduced and the cost can be reduced. Also, even if the height of the ground partially changes due to miniaturization, the effect is small, so
It is not necessary to secure a very strong strength, and the cost can be reduced from this point as well. Since the conventional pedestrian auxiliary signal light is configured to be long over the entire length of the stop line, the influence is large when the height of the ground and the like partially changes, and the strength is high. It is necessary to secure the cost, which is unavoidable. In this respect, in the first aspect, since the light emitters are two-dimensionally arranged, it is not necessary to configure the elongated shape. Moreover, since the light emitters are two-dimensionally arranged, the light emitting area can be increased and the visibility can be improved.

It is conceivable to house a plurality of light emitters in individual housings and arrange them individually on the ground in a scattered manner. However, it is extremely troublesome to embed each light emitter. It is necessary and unavoidable for cost increase. In contrast,
In the first aspect, since a plurality of sets of light emitters (each set is made up of a plurality of light emitters) are arranged in one housing, the burying work does not require labor and is inexpensive.

A pedestrian auxiliary signal light according to a second aspect of the present invention is the pedestrian auxiliary signal light according to the first aspect, wherein one of the plurality of light emitters emits light of a different color. It is red, and the emission color of the other one of the plurality of sets of light emitters is blue. As a result, the function of a normal pedestrian auxiliary signal light can be completely assisted. However, the pedestrian auxiliary signal light according to the first embodiment may include, for example, a yellow light emitter set in addition to the red light emitter set and the blue light emitter set.

A pedestrian auxiliary signal light according to a third aspect of the present invention is the pedestrian auxiliary signal light according to the first or second aspect, wherein the pedestrian auxiliary signal light is illuminated and displayed by each of the plurality of light emitters. The plurality of sets of light emitters are arranged so that the patterns are different from each other. In this case, the signal can be transmitted not only by the difference in color but also by the shape, so that, for example, even a color-blind person can easily identify the signal. The shape pattern may be a character pattern, as will be described later, or an arbitrary mark or the like.

A pedestrian auxiliary signal light according to a fourth aspect of the present invention is the pedestrian auxiliary signal light according to the third aspect, wherein the shape pattern which is displayed by each of the plurality of sets of light-emitters is displayed in letters. It is a pattern.

A pedestrian auxiliary signal light according to a fifth aspect of the present invention is the pedestrian auxiliary signal light according to any one of the first to fourth aspects, wherein the plurality of sets of the plurality of sets are provided in the light emitting window portion of the casing. A dichroic mirror that transmits light of the wavelengths emitted by the light emitters and substantially reflects light of other wavelengths is provided.

According to the fifth aspect, sunlight having almost all wavelength components is reflected by the dichroic mirror and does not enter the inside of the housing. Therefore, the temperature rise inside the housing due to the radiant heat of sunlight is reduced, and the malfunctions due to the temperature rise of the electronic components arranged inside the housing are reduced. Then, the dichroic mirror transmits light of a wavelength emitted by each of the plurality of sets of light emitters,
There is no problem with light emission by the light emitter.

A pedestrian auxiliary signal light according to a sixth aspect of the present invention includes a plurality of pedestrian auxiliary signal lights according to any one of the first to fifth aspects, and the plurality of pedestrian auxiliary signal lights cross each other. These are scattered around the pedestrian stop position on the sidewalk.

According to the sixth aspect, since the plurality of pedestrian auxiliary signal lights are scattered around the pedestrian stop position on the pedestrian crossing, the signals can be transmitted over a wide range. it can. Although it is inevitable to increase the cost by constructing a large size without arranging them in a scattered manner as described above, each pedestrian auxiliary signal light can be downsized as described above, and therefore the cost is low as a whole.

There is. An O-ring 8 is interposed between the transparent plate 4 and the support frame 5 in order to ensure waterproofness so that water does not enter the inside of the housing.

The housing body 2 has a stepped portion, the support frame 5 is fitted to the stepped portion, and the screw 9 inserted in the support frame 5 is screwed into the screw hole provided in the housing body 2. As a result, the support frame 5 (hence the lid 3) and the housing body 2 are fixed. An O-ring 10 is interposed between the support frame 5 and the housing body 2 so as to ensure waterproofness so that water does not enter the inside of the housing.

In the present embodiment, a plurality of red LEDs 11R (one set of light emitters) and a plurality of blue LEDs 11B (one set of light emitters) are two-dimensionally mixed in the housing. It is arranged. Multiple red LEDs 11R
And the plurality of blue LEDs 11B are mounted on the printed board 12, the printed board 12 is arranged below the transparent plate 4, and the red light and the blue light emitted from the LEDs 11R and 11B are radiated to the outside through the transparent plate 4. It has become so. In this embodiment, the printed circuit board 12 is fixed to the support frame 5 with the screws 13 and the spacers 14.

In the present embodiment, the plurality of red LEDs are
11R and the plurality of blue LEDs 11B are evenly distributed over substantially the entire area of the transparent plate 4, and the plurality of red LEDs 1 are provided.
The shape pattern emitted and displayed by 1R and the shape pattern emitted and displayed by the plurality of blue LEDs 11B have the same substantially rectangular shape.

Further, in the present embodiment, a dichroic mirror 15 is provided in the light emitting window portion of the housing for transmitting the light of the wavelengths emitted by the LEDs 11R and 11B and substantially reflecting the light of other wavelengths. . That is, in the present embodiment, the dichroic mirror 15 is arranged on the lower surface of the transparent plate 4, and the dichroic mirror 15 is held by the pressing member 16 fixed to the support frame 5 by the screw 13 and the spacer 14 together. Is fixed against. However, in the present invention, such a dichroic mirror 15 does not necessarily have to be provided.

A pipe 17 for protecting a wiring cable (not shown) and guiding the wiring cable to the inside of the casing is attached to the side of the casing body 2.

The red LED 11R and the blue LED 11B may be interlocked so that the light emitting patterns of the red LED 11R and the blue LED 11B completely match the light emitting patterns of the red light emitting portion and the blue light emitting portion of the pedestrian traffic light on the ground. The two may be linked so as to be partially changed. For example, in the case where the pedestrian traffic light on the ground has a yellow light emitting portion, when the yellow light emitting portion is lit, the blue LED 1
You may blink 1B. Also, the blinking of the blue light-emitting part and the lighting of the yellow light-emitting part of the pedestrian traffic light on the ground indicate that the end of the crossing is promoted, not the start of the crossing, so basically only at the start of the crossing. In the pedestrian auxiliary signal light 1 that the pedestrian will see, when the blue light emitting portion of the pedestrian signal light on the ground is blinking or the yellow light emitting portion is lit, the blue LED 11B is not emitted and the red LE is emitted.
The D11R may be made to emit light.

The pedestrian auxiliary signal light 1 thus constructed is embedded in the ground 20 near the pedestrian stop position on the pedestrian crossing, as shown in FIG. For example,
As shown in FIG. 3, three pedestrian auxiliary signal lights 1 are scatteredly arranged near the stop position on one side of the pedestrian crossing 30,
Three auxiliary signal lights 1 for pedestrians are also scattered near the stop position on the opposite side of the pedestrian crossing 30. However, in the present invention, one pedestrian auxiliary signal lamp 1 may be arranged on each side of the pedestrian crossing 30, and the number and arrangement pattern thereof can be arbitrarily determined. In FIG. 3, 31
Is a roadway, 32 is a sidewalk, and 30a is a stop line of the pedestrian crossing 30.

The plurality of pedestrian auxiliary signal lights 1 thus arranged in a scattered manner constitute the pedestrian auxiliary signal light device according to the embodiment of the present invention.

However, in this case, the sum of the areas of the light emitting portions of the respective colors is the area of the entire light emitting portion, so that the size must be increased and the cost is inevitably increased. In addition, if the size is increased, the effect will be great if the height of the ground partially changes, and it is necessary to secure sufficiently strong strength to prevent damage due to it, which also increases costs. I cannot escape. On the other hand, in the present embodiment, a plurality of red L
Since the ED 11R and the plurality of blue LEDs 11B are arranged two-dimensionally in a mixed manner, the light emitting portions of the respective colors are integrated, and the total area of the light emitting portions is considerably smaller than when the light emitting portions of the respective colors are divided. can do. Therefore,
According to the present embodiment, the size can be reduced and the cost can be reduced. Further, even if the height of the ground partly changes due to miniaturization, the effect is small, so there is no need to secure a very strong strength, and cost can be reduced from this point as well. . Since the conventional pedestrian auxiliary signal light is configured to be long over the entire length of the stop line, the influence is large when the height of the ground and the like partially changes, and the strength is high. It is necessary to secure the cost, which is unavoidable. In this respect, in the present embodiment, since the LEDs 11R and 11B are two-dimensionally arranged, it is not necessary to make the LED elongated. Besides, LED
Since 11R and 11B are arranged two-dimensionally, the light emitting area can be increased and the visibility can be improved.

For example, in the above-mentioned embodiment, the LED is used as the light emitting device, but the light emitting device is not necessarily limited to the LED.

In the above embodiment, the red LED 1
Although only 1R and blue LEDs were used, the emission colors are not limited to red and blue, and yellow LEDs may be added, for example.

Further, in the above-described embodiment, as described above, the shape pattern displayed by the plurality of red LEDs 11R and the shape pattern displayed by the plurality of blue LEDs 11B are the same. Red LED11R and blue L
The ED 11B may be arranged. In this case, the signal can be transmitted not only by the difference in color but also by the shape, so that, for example, even a color-blind person can easily identify the signal.
