Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a traffic signal that uses a high-intensity LED in a lighting section to facilitate the determination of the color being lit and can display various signs by a computer program.

[0002]

[Prior art]

 In a conventional traffic signal, the lighting unit is a light bulb. The color of the light emitted depends on the color of the light bulb, and it is only possible to turn on the color of each light bulb. Since light bulbs are also used for auxiliary signals such as arrows, only the type of auxiliary signal is required, and the traffic signal becomes larger by that amount, so it may be difficult to judge the signal information at an instant. , It may interfere with safe traffic. On the other hand, when the light of the sun shines straight into the traffic signal in the morning or in the evening, the light bulbs that are not lit become bright and it is difficult to determine which color light bulb is lit. The second drawback is the short life of the light bulb. It occurs because filament is used as the light source of the light bulb. Another drawback is that it uses a power line as a power source, so it cannot be used when electricity is not supplied due to a power failure.

[0003]

[Problems to be solved by the device]

 It is necessary to make it easy to determine the traffic signal information in order to instantly read the signal information when looking at the traffic signal. To that end, it is desirable to reduce the number of traffic lights that are illuminated. It must be possible to instantly determine which color is lit even in the morning, in the evening, or when the sunlight directly enters the traffic light. If the life of the light-emitting part is not long, the traffic signal itself will be out of order, making it impossible to use the road safely and it is economically inconvenient. It must be usable even if power is cut off due to a power outage.

[0004]

[Means for Solving the Problems]

 The structure is as follows. (A) Attach the lighting part of (1) to the main body of (2). (B) The eaves of (3) are provided above the lighting part of (1). (C) Inside the main body of (2), the lighting control circuit of the lighting part, the memory of the program of the lighting sign, and the power supply part for driving these and the lighting part are housed. The apparatus is operated as described above.

[0005]

[Action]

 As shown in FIG. 1, the lighting part of (1) is attached to the main body of (2). In addition, the eaves of (3) are installed above the lighting part of (1) to make it easier to see the markings even when the altitude of the sun is high or during precipitation. Inside the main body of (2), the lighting control circuit (5) of the lighting unit (4) shown in FIG. 2, the memory (6) of the program of the lighting indicator, and the power supply unit for driving these and the lighting unit ( 7) is stored. As shown in FIG. 3, the lighting portion of (1) is a combination of high-luminance LEDs of three colors of red, blue, and yellow arranged on the entire surface. These send the data about the marking format sent from the memory (6) of the lighting sign program to the lighting control circuit (5), and perform marking according to which of the high-intensity LEDs is turned on according to the data. In addition to the power line, the power supply section (7) is also equipped with a rechargeable battery, and plays the role of an exchange communication unit even in the event of a power failure. If a rechargeable battery is installed outside the traffic signal, a solar battery can be used to charge the rechargeable battery. Basically, the traffic signal of the present invention can function as a traffic signal only by having one lighting unit.

[0006]

【Example】

 As shown in FIG. 4, by combining three lighting units of the present invention, as a traffic light at a complicated intersection, by providing arrow signals on both sides and providing a traffic light with ordinary three-color marking in the center, An easy-to-understand traffic signal can be realized. Since the traffic light itself is light and there are few restrictions on the mounting position, various devices can be added. For example, it has a function of notifying the control department that a signal has failed, and a vehicle number reading device for cracking off on illegal vehicles.

[0007]

[Effect of device]

 Since there are few marking points, it is possible to instantly read the signal information when looking at the traffic signal. Even in the morning, in the evening, or when the sunlight directly enters the traffic light, the colors other than the ones that are lit are not visible, so you can instantly determine which color is lit. The long life of the light emitting part reduces the breakdown of the traffic signal itself, allows safe use of the road, and is economically advantageous. Even if power is cut off due to a power outage, it can be used with the built-in rechargeable battery. It consumes less power than a light bulb and can be used with a built-in rechargeable battery. Since the traffic light itself is light and there are few restrictions on the mounting position, various devices can be added. For example, it has a function of notifying the control department that a signal has failed, and a vehicle number reading device for cracking off on illegal vehicles.
