Description

  The present invention relates to a pedestrian signal lamp, and more particularly, to an LED type pedestrian signal lamp using an LED (light emitting diode) as a light source.

  In recent years, LED-type signal lamps have been put into practical use for the purpose of reducing power consumption and labor required for maintenance and management.

  As an LED type pedestrian signal lamp, for example, an LED unit in which a large number of LEDs (light emission color: red or blue) are mounted on a printed wiring board is used as a light source, and the LED unit is accommodated in a lamp case. The front cover arranged on the front side of the LED group has a structure in which a translucent part (doll part) and a light shielding part of a pattern (doll) shaped like a pedestrian are provided, and only the doll part emits light in red or blue. There is a specification signal lamp (for example, refer to Patent Document 1).

  In addition, when a conventional pedestrian signal lamp switches from a blue lighting display of “crossable” to a red lighting display of “non-crossable”, it indicates that the signal is switched by blinking the blue display. He urged the attention of crossing. However, elderly people and children sometimes got stuck because the signal turned red while crossing the pedestrian crossing. Moreover, even if it is not an elderly person, the remaining lighting time of a signal cannot be predicted until the signal starts blinking, so it may be necessary to hurry or to cross a pedestrian crossing. In addition, the red light is frustrating or forcibly crossing because it is not known how long the waiting time is.

As one of methods for solving such inconvenience caused by the unknown remaining time of signal display, for example, a pedestrian signal lamp as described in Patent Document 2 has been proposed. In this type of signal lamp, zebra patterns indicating the remaining time of the display signal are provided on both the left and right sides of the doll symbols of the upper and lower light emitting sections. For example, in the case of a red signal, the center doll symbol lights up in white, and the left and right zebra patterns of the doll symbol illuminate in red and turn off sequentially from the top as time passes. It has come to show.
JP 2001-81738 A JP-A-6-96388

  Unlike the current general signal display, the signal light device for pedestrians described in Patent Document 2 is a method in which the left and right zebra patterns of the doll pattern are lit in red or blue. When the time is short, only a part of the zebra pattern is lit in red, and the red signal's original “impossible to cross” indication is diminished and the distinctiveness is lowered. There is a risk of inviting. In particular, since visibility is lowered at night, such signal display is not preferable in consideration of the safety of pedestrians.

  Therefore, the lighting form of the doll symbol of the traffic signal lamp indicating “crossing is impossible” or “crossing is possible” must be a display that can be easily seen by anyone and can be appropriately judged without changing the current lighting pattern. That is, it is preferable to display the remaining time in a range that does not affect the display of the original red signal or blue signal in compliance with the standards of the current traffic signal lamp.

  Accordingly, the present invention has been made in view of the above-described problems, and ensures a standard size and form that can comply with the standards of current traffic signal lamps regarding the color and shape of the light emitting part, while at the time of red light. It is possible to display the waiting time of the car and the remaining crossing time at the time of the green light, to set a time guide when crossing the pedestrian crossing, to relieve irritability and to encourage safe crossing The present invention provides an LED-type pedestrian signal lamp excellent in distinguishability and visibility regardless of whether it is day or night.

  In order to achieve the above-described object, in the LED type pedestrian signal lamp according to the present invention, a first light emitting unit that displays “crossing is impossible” and a second light emitting unit that displays “crossing is possible” are arranged above and below. ing.

  The light-transmitting plate provided in each light-emitting unit is provided with a light-shielding part that shields the light-transmitting part of the doll pattern and the part other than the light-transmitting part, and the LED arranged behind the light-transmitting part of the doll pattern Puppet designs are displayed by group. In addition, a plurality of remaining time display light transmitting portions are provided in the vicinity of the end portions of the respective light transmitting plates, and the remaining time display light transmitting portions are arranged by LEDs arranged behind the remaining time display light transmitting portions. Is configured to light up.

  When the doll symbol of the first light emitting unit having such a configuration is lit on, the second light emitting unit lights the remaining time display translucent unit group, and changes the lighting mode of the remaining time display translucent unit group to the time. It is characterized by displaying the waiting time until crossing is possible by changing with the progress of.

  Further, according to the present invention, when the doll symbol of the second light emitting unit having the above-described configuration is turned on, the remaining time display translucent unit group is turned on in the first light emitting unit, and the remaining time display translucent unit group is turned on. It is characterized in that the traversable time is displayed by changing the lighting form with the passage of time.

  In addition, the present invention lights one doll symbol of the first light emitting unit or the second light emitting unit configured as described above, and lights the remaining time display translucent unit group in the other light emitting unit. By changing the lighting mode of the time display translucent part group with the passage of time, the traversable time or the waiting time until traversable is displayed.

  According to such an invention, “crossing is impossible” or “crossing is possible” is displayed on either one of the light emitting units, and at the same time, the crossing possible time or the waiting time until crossing is possible on the other light emitting unit. , "No crossing" without affecting the display form of each light emitting unit of "crossing impossible" or "crossing possible" as before, and without adding a new display unit for time display to the traffic light Alternatively, the remaining time can be shown as a display separate from the “crossing allowed” display. Therefore, while complying with the standards of traffic signal lamps, the remaining time of signal display can be notified by the number of lighting of the remaining time display translucent part, alleviating the irritability of pedestrians, or forcibly crossing And can be regulated.

  In the LED-type pedestrian signal lamp having the above-described configuration, it is preferable that the lighting mode of the remaining-time-displaying translucent part group is configured so that the lights are sequentially turned off as time passes. Or it is preferable that the lighting form of the translucent part group for remaining time display is comprised so that light may be decreased in order with progress of time.

  Thereby, the pedestrian can easily determine the crossing possible time or the waiting time until the crossing is possible, and the crossing safety of the pedestrian can be improved.

  Moreover, it is preferable that the lighting mode of the remaining time display translucent part group that is turned off or dimmed in this way is configured to be turned off or dimmed in order from the top as time elapses. Thus, by changing the lighting state of the remaining time display translucent part group in order from the top, it is easier to understand, and it is possible to show the pedestrian the time that can be crossed or the waiting time until the crossing is possible.

  Further, in the present invention, the translucent plate is provided with a translucent frame at the periphery of the remaining time display translucent unit group, and the translucent unit frame is formed by the LED group disposed behind the translucent unit frame. It is configured to illuminate, and at the same time as the transmissive part group for displaying the remaining time is lit, the transmissive part frame around it is also lit, thereby starting the lighting of the transmissive part group for displaying the remaining time. The ratio of the remaining time to the lighting time until the end may be displayed.

  With such a configuration, the lighting time from the start to the end of lighting of the remaining time display translucent part group is indicated by the translucent part frame, and the lighting mode of the remaining time display translucent part group is indicated inside the translucent part frame. Since it changes, the pedestrian can know at a glance the ratio of the remaining time to the lighting time, and can immediately determine the crossing possible time or the waiting time until crossing is possible.

  Moreover, the LED type pedestrian signal lamp according to the present invention has a lighting control unit having a timer for measuring a lighting time from the start to the end of lighting of each light emitting unit, and the first light emitting unit or the first light emitting unit by the timer. The previous lighting time information in each of the two light emitting units is acquired, and the remaining time until lighting switching is calculated based on this lighting time information.

  According to this invention, since the lighting control unit acquires lighting time information and controls lighting, the lighting time from the start to the end of lighting is grasped at any time to calculate the crossing possible time or the waiting time until crossing is possible, Can be adjusted automatically.

  In addition, the LED-type pedestrian signal lamp lights the doll symbol in red in the first light emitting unit and the translucent unit for remaining time display in blue, and displays the doll symbol in blue in the second light emitting unit and the remaining time display. It is preferable to unify the luminescent color of each light-emitting part when the light-transmitting part is lit in red. That is, when the signal is red, the doll symbol of the first light emitting unit is displayed in red and the remaining time display translucent unit of the second light emitting unit is lit red. When the signal is blue, the doll symbol of the second light emitting unit is displayed in blue. In addition, the remaining time display translucent portion of the first light emitting portion is also lit in blue.

  Thereby, a clear signal display can be configured to improve the distinguishability and visibility, and an appropriate determination can be made at the time of crossing the road without causing confusion to the pedestrian.

  According to the LED type pedestrian signal lamp 1 of the present invention configured as described above, the waiting time at the time of a red signal is ensured while ensuring the standard size and form that can comply with the standards of the current traffic signal lamp. It is possible to display the remaining available crossing time at the time of a green light, to easily determine whether or not a pedestrian can cross the road, and to restrict annoying and unreasonable crossing at the time of a red light. Thereby, the crossing safety | security of a pedestrian can be improved and the prevention of a traffic accident can be aimed at.

  Hereinafter, the best mode for carrying out an LED type pedestrian signal lamp according to the present invention will be described with reference to the drawings. In addition, although many forms can be considered as the LED-type pedestrian signal lamp according to the present invention, in the following description, three forms of them and modifications thereof will be shown, and constituent elements overlapping with each embodiment will be described. Examples 2 and 3 will be described using the same reference numerals as those in Example 1 below, and detailed description thereof will be omitted.

[Example 1]
1 to 3 show Embodiment 1 of the LED type pedestrian signal lamp of the present invention, FIG. 1 is a front view showing the pedestrian signal lamp, and FIG. 2 is an exploded view showing a second light emitting portion of the signal lamp of FIG. FIG. 3 is a block diagram showing a configuration of a lighting control system in the signal lamp of FIG.

  In the LED-type pedestrian signal lamp 1, a first light emitting unit 1A that displays "crossing is impossible" and a second light emitting unit 1B that displays "crossing is possible" are arranged vertically. On the front side of the LED-type pedestrian signal lamp 1, ridges 3 and 3 are arranged to cover the upper region on the front side of the light emitting units 1A and 1B.

  Each of the light emitting units 1A and 1B includes an LED substrate 12 on which a large number of LEDs (13B and 13R) are mounted, a front cover 14, a translucent plate 15, a presser cover plate 16, a unit case 11, and the like. The unit case 11 is a resin molded product (for example, made of ABS resin), and an LED substrate 12 is accommodated in the case. The front cover 14 is made of a resin molded product formed into a lens shape with a transparent resin such as polycarbonate resin.

  The translucent plate 15 is made of a member obtained by applying a light shielding film to a transparent resin plate such as, for example, a methacrylic resin plate. The translucent portion 151 of the doll pattern shaped like a pedestrian and the portions other than the translucent portion 151 are shielded. A light shielding portion 152 is provided. In the illustrated translucent plate 15, the doll symbol C <b> 1 of the translucent part 151 indicates “cannot traverse”, and the doll symbol C <b> 2 indicates “can traverse”.

  A group of LEDs mounted on the LED substrate 12 is arranged behind the light transmitting portions 151 of the doll symbols C1 and C2. The light emission color of the LED group is red (LED13R) for the doll symbol C1 of the first light emitting unit 1A and blue (LED13B) for the doll symbol C2. Thereby, the translucent part 151 of the translucent plate 15, that is, the doll symbol C1 can be lit in red and the doll symbol C2 can be lit in blue.

  Further, in the present invention, a total of ten remaining time display light transmitting portions 18 a and 18 b are provided in the vicinity of the end portion of each light transmitting plate 15. The remaining time display light-transmitting portions 18a and 18b are substantially square light-transmitting portions, and are arranged at equal intervals on the left and right sides of the doll symbols C1 and C2. Then, behind the remaining time display translucent portions 18a and 18b, a blue LED group 13B is arranged in the first light emitting unit 1A, and a red LED group 13R is arranged in the second light emitting unit 1B. That is, the remaining time display translucent portions 18a on the left and right sides of the doll symbol C1 can be lit in blue, and the remaining time display translucent portions 18b on the left and right sides of the doll symbol C2 can be lit in red. Yes.

  The translucent plate 15 and the presser cover plate 16 having such a configuration are arranged between the front end surface of the unit case 11 and the front cover 14 in a state of being overlapped with each other. In this state, the front cover 14 is screwed onto the unit case 11. The light emitting portions 1A and 1B are configured to be held between the unit case 11 and the front cover 14 by being fixed.

  Such a pedestrian signal lamp 1 lights and displays one doll symbol of the first light emitting unit 1A or the second light emitting unit 1B, and at the same time, transmits all remaining time display translucent units 18a, It is set as the mechanism which lights 18b. As the time elapses, each remaining time display translucent portion 18a, 18b of the other light emitting portion is turned off in turn, and the lighting mode is changed to change the remaining light emitting portion where the doll symbol is turned on. It is possible to inform the pedestrian of the lighting time of the vehicle, that is, the crossing time or the waiting time until the crossing is possible.

  As shown in FIG. 3, a lighting control unit 5 is provided in the lighting control system of the pedestrian signal lamp 1. A signal lighting signal is transmitted to the lighting control unit 5 from a signal controller (not shown) at a road intersection or the like. Further, the power supply voltage for driving the LED is supplied from the power supply unit 6 to the lighting control unit 5. Thereby, the lighting state of 1st light emission part 1A and 2nd light emission part 1B is made to switch with progress of time.

  Further, the lighting control unit 5 is provided with a timer T that measures the lighting time from the start to the end of each of the first and second light emitting units 1A and 1B. The previous lighting time information is acquired, and the remaining time until lighting switching can be calculated based on this lighting time information. Then, the lighting control unit 5 supplies the power supply voltage from the power supply unit 6 to the corresponding LED group in accordance with the signal lighting signal transmitted from the signal controller.

  Next, the lighting form of each light emission part 1A, 1B of the signal lamp device 1 for pedestrians of embodiment is demonstrated, referring FIG. 4, FIG.

  When the signal lighting signal from the signal controller is a signal to light the first light emitting unit 1A, the lighting control unit 5 supplies the red LED group 13R of the first light emitting unit 1A to the power supply voltage from the power source unit 6. Is supplied, and as shown in FIG. 4A, the doll symbol C1 is lit in red, indicating that “crossing is impossible”. At the same time, the power supply voltage from the power supply unit 6 is also supplied to the red LED group 13R of the second light emitting unit 1B, and the remaining time display translucent unit 18b is lit in red. At this time, the timer T starts measuring the lighting time from the start of lighting of the first light emitting unit 1A.

  With the passage of time, the red LED group 13R of the second light emitting unit 1B is turned off sequentially from the portion corresponding to the upper left remaining time display light transmitting portion 18b, and the remaining time display light transmitting portion that is lit. The number of 18b decreases. For example, as shown in FIG. 4 (b), if the upper left three of the remaining time display translucent part 18b are turned off, the pedestrian waits for a while after the signal lamp 1 turns red. Can be determined.

  When the time further elapses, all of the remaining time display translucent portion 18b on the left side of the second light emitting unit 1B is turned off, and then the remaining time display translucent portion 18b on the right side is turned off sequentially from the top. For example, as shown in FIG. 4C, if the remaining time display translucent part 18b is turned on in the remaining two stages, the pedestrian can determine that the waiting time of the red signal is reduced.

  When the signal lighting signal from the signal controller is a signal to light the light emitting unit 1B, the lighting control unit 5 supplies the power supply voltage from the power source unit 6 to the blue LED group 13B of the second light emitting unit 1B. Then, as shown in FIG. 5 (a), the doll symbol C2 is lit in blue, indicating that “crossing is possible”. At the same time, the power supply voltage is also supplied to the blue LED group 13B of the first light emitting unit 1A, and the remaining time display translucent part 18a is turned on.

  The lighting time is measured by the timer T, and the remaining time display translucent part 18a of the first light emitting part 1A is turned off sequentially from the upper left as time elapses. For example, at the stage shown in FIG. 5 (b), the pedestrian can determine that a certain time has passed since the signal lamp 1 turned green, and when the stage shown in FIG. 5 (c) is reached, It is possible to determine that the remaining crossing time is short, and it is possible to take measures such as crossing at the next green light without crossing with this green light.

  As described above, according to the pedestrian signal lamp 1, the remaining waiting time at the time of the red signal and the guideline of the crossing possible time at the time of the green signal are walked by the changing number of the remaining time display translucent portions 18a and 18b. People can be informed, annoyance can be alleviated, and unreasonable crossing can be restricted, and traffic accidents can be prevented.

  The remaining-time display light-transmitting portions 18a and 18b are turned off in order from the upper left to the lower, and then turned off from the upper right to the lower, as well as from the lower right to the upper. Any form may be used as long as it is a change form having a certain regularity, such as a form to be turned off or a form in which the light is turned off from top to bottom simultaneously. Further, it is possible to increase the number of the remaining time display translucent portions 18a and 18b from 10 as illustrated and sequentially turn off the light by two. The number of the remaining time display translucent portions 18a and 18b is appropriately determined in consideration of visibility from pedestrians according to the size of the road where the pedestrian signal lamp 1 is provided, the waiting time of signals, and the like. Preferably it is selected.

  In addition, the pedestrian signal lamp device 1 according to the present invention is not limited to the illustrated form with respect to the shape and arrangement position of the remaining time display translucent portions 18a and 18b, and is visually recognized according to the size of the road. Any shape and position that is easy to use may be used.

  Further, in the above embodiment, the description has been given of the case where the first light emitting unit can display the crossing possible time and the second light emitting unit can display the waiting time until crossing is possible, but the present invention is not limited thereto. However, it may be configured such that only one of the crossing time and the waiting time until crossing can be displayed.

[Example 2]
Next, a second embodiment of the LED type pedestrian signal lamp according to the present invention will be described.

  FIG. 6: is a front view which shows Example 2 of the LED type pedestrian signal lamp device of this invention. The LED-type pedestrian signal lamp device 1 of this embodiment is characterized by the configuration of the remaining time display translucent portion arranged near the end of each translucent plate (15) and its lighting form. The components are the same as those in the first embodiment.

  As shown in the drawing, in each of the light emitting units 1A and 1B, there are 16 remaining time display translucent portions 19a and 19b, 8 on the left side of the doll symbols C1 and C2, and 8 on the right side of the doll symbols C1 and C2. Each is provided. These remaining time display translucent portions 19a and 19b are rectangular translucent portions, and are arranged at equal intervals. Behind each remaining time display translucent part 19a, 19b, a blue LED group (13B) is arranged in the first light emitting part 1A, and a red LED group (13R) is arranged in the second light emitting part 1B. (See FIGS. 2 and 3).

  The lighting mode of the remaining time display translucent portions 19a and 19b is configured to be dimmed in order from the top and the left simultaneously with the passage of time. That is, when the doll symbol C1 of the first light emitting unit 1A is lit in red and indicates “cannot cross”, at the same time, in the second light emitting unit 1B, all the remaining time display translucent portions 19b are first displayed in red. Illuminated. The remaining-time-displaying translucent part 19b that has been lit is moved downward from the portion corresponding to the uppermost remaining-time-displaying translucent part 18b in the left and right LED groups (13R) as time passes. It is configured so that it will fade out in order.

  The dimming of the LED group is controlled, for example, by modulating the pulse width of the voltage supplied to the plurality of LEDs (PWM control in synchronization with the power supply frequency) with reference to the peak point of the AC voltage waveform from the AC power supply. The light intensity is adjusted to about 10% to 15% of the maximum luminance. As a result, the number of remaining-time display light-transmitting portions 18b that are lit at the maximum luminance sequentially decreases with the passage of time.

  Therefore, as illustrated in FIG. 6 (a), if the remaining time display translucent portion 19b is dimmed in both the left and right sides and the remaining lower half is lit, the pedestrian can use this signal light. It can be determined that about half of the lighting time from when the device 1 becomes a red signal to when the device 1 switches to the blue signal has elapsed.

  When the time further elapses and the lighting time of the first light emitting unit 1A ends, all of the remaining time display translucent portion 19b is turned off. Then, the signal lighting signal from the signal controller transmits a signal indicating that the light emitting unit 1B is turned on, and the doll symbol C2 of the second light emitting unit 1B is lit in blue to indicate that “crossing is possible”. At the same time, the power supply voltage is also supplied to the blue LED group (13B) of the first light emitting unit 1A, and all the remaining time display translucent portions 19a are lit in blue.

  For example, as shown in FIG. 6 (b), if the remaining time display translucent portion 19a has been dimmed by six from the top and the left, the pedestrian will see this signal lamp 1 turn green. It can be determined that about three-quarters of the lighting time from switching to a red signal has elapsed, and the remaining crossable time is short.

  With this configuration, the signal lamp 1 is completely extinguished as time passes when the remaining time display translucent portions 19a and 19b display the crossing possible time or the waiting time until crossing is possible. Instead of going, it is lit in a dimmed state that is dimmable and visible from the top, so that the surroundings of the signal lamp 1 are dark at night, etc., and it is difficult to see the display of each light emitting unit 1A, 1B. Even if it exists, it can be made easy to grasp | ascertain how much the lighting form of the translucent part group for remaining time display changed.

  Therefore, the change in the lighting mode of the remaining-time display translucent portions 19a and 19b can be shown by comparing the lighting part at the maximum luminance and the lighting part in the dimmed state regardless of the ambient brightness of day and night. The ratio of the remaining time to the lighting time from the lighting start to the end of the remaining time display translucent part group can be surely notified to the pedestrian.

[Example 3]
Next, a third embodiment of the LED type pedestrian signal lamp according to the present invention will be described.

  FIG. 7: is a front view which shows Example 3 of the LED type pedestrian signal lamp device of this invention. In the LED type pedestrian signal lamp 1 of this embodiment, in each of the light emitting portions 1A and 1B, a light transmitting portion frame 21 is provided at the peripheral portion of the light transmitting portion group for displaying the remaining time of the light transmitting plate (15). The other components are substantially the same as those in the first embodiment.

  As shown in the figure, the translucent part frame 21 of the remaining time display translucent part group is formed to surround the remaining time display translucent parts 20a and 20b provided on the left and right of the doll symbols C1 and C2. ing. And behind this translucent part frame 21, in the 1st light emission part 1A, blue LED group (13B) is arranged, and in 2nd light emission part 1B, red LED group (13R) is arranged. That is, LED groups having the same color as the light emission color of the remaining time display translucent part group surrounded by the translucent part frame 21 are respectively arranged behind the translucent part frame 21. Thereby, the translucent frame 21 is configured to light up in blue or red.

  Each of the translucent frame 21 indicates a lighting time from the start to the end of lighting of the remaining time display translucent unit group. Then, as the time elapses, the lighting mode of the remaining time display translucent part group is changed inside each translucent part frame 21.

  For example, as shown in FIG. 7 (a), while the doll symbol C1 of the first light emitting unit 1A is lit in red and “uncrossable” is displayed, the second light emitting unit 1B has a transparent frame. 21 is lit red. Inside the light-transmitting light-transmitting part frame 21, the remaining-time display light-transmitting part 20b is sequentially turned off from the top as time passes, and a waiting time until traversing is possible is displayed.

  Further, as shown in FIG. 7B, while the doll symbol C2 of the second light emitting unit 1B is lit in blue and “crossing is possible” is displayed, the first light emitting unit 1A is lit in blue. Inside the translucent frame 21, the remaining time display translucent portion 20a is sequentially turned off from the top as time elapses, and the crossable time is displayed. The lighting mode of the remaining time display translucent portions 20a and 20b is changed so that both the left and right are turned off sequentially from the top in the same manner as in the second embodiment.

  Thus, when the remaining time display translucent portions 20a and 20b are turned on to display the crossing possible time or the waiting time until crossing is possible, the surrounding translucent portion frame 21 is also turned on simultaneously. Since the ratio of the remaining time to the entire lighting time is shown, it becomes easy to judge how much time has passed even in a situation where it is difficult to visually recognize the display of each light emitting unit 1A, 1B such as at night, Pedestrian crossing safety can be improved.

  The lighting mode of the remaining-time display translucent part group may be a form in which the light is not only turned off in order from the top inside the translucent part frame 21 but also dimmed. Moreover, although it is easy to visually recognize that the luminescent color of the translucent part frame 21 is red or blue as described above, the present invention is not limited to these luminescent colors and may be any color.

  INDUSTRIAL APPLICABILITY The present invention can be effectively used as a pedestrian signal lamp for enhancing pedestrian crossing safety at an intersection or the like.
