JPH04134521U - traffic sign - Google Patents

Abstract

(57) [Summary] (with modifications) [Purpose] When a car is detected at night, the traffic sign lights up in a color that complies with the law. [Structure] A white light emitter is attached to a sign board, and when a sensor detects a traveling vehicle at night, the white light emitter emits light using power obtained from a solar cell. [Effects] The white light emitting material allows the sign to be displayed in white, complying with regulations.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for traffic signs that properly convey traffic information to drivers at night. It is related to

0002

[Conventional technology]

Traffic signs include sign boards attached to poles and lamps that can be used at night. Some of them have been devised so that they can be clearly understood even in the middle of the day.

0003

[Problem that the idea aims to solve]

In the above configuration, if the sign board is simply attached to the pole, Traffic safety is often difficult to see, noticed late, or overlooked. This is a problem in terms of all countermeasures.

0004 On the other hand, those combined with lamps do not have the above problems, but the electricity cost increases, In addition, in the case of a place without electric light lines, construction work such as wiring is required each time, making the installation difficult. Preparation costs are high.

[0005] The purpose of this invention is to save energy while ensuring that signs are clearly visible even at night, while still being legal. The objective is to provide traffic signs that comply with the regulations.

[0006]

[Means to solve the problem]

The configuration of the present invention is as follows.

[0007] Draw cut-out letters, symbols, and shapes on the sign board, and paste colored luminescent materials on the back side. When the light from a running vehicle is sensed, the power is turned on and the colored luminous body emits light. A traffic sign composed of punched letters, symbols, and figures in color to represent night time.

[0008] Solar cells are used to store electricity during the day, and this power is used to power colored light emitters. Turn on and off the power switch to turn on the lights of vehicles such as cars and motorcycles. This is done by a controller driven by a car detection sensor that generates a signal when detected. A traffic sign consisting of.

[0009] In addition, colored luminescent material may be applied alone or in combination to the surface of the sign board. A sign board can also be constructed by combining them.

0010

[Effect]

During the day, electricity is obtained from solar cells, and this electricity is stored in a battery. When the vehicle detection sensor detects the lights of a running vehicle, this sensor sends a signal to the controller. Then, the controller turns on the power switch of the colored light emitter to cause the colored light emitter to emit light. system Goki turns off the colored light emitters when the car passes a traffic sign. Na The controller performs the above control only at night using the signal from the day/night identification sensor, and does not operate during the day. Power consumption is reduced without any problems.

【Example】

Figure 1 shows a traffic sign according to the present invention. The code 1 is the pole, 2 is the signboard, and 3 is the control. This control device 3 includes a vehicle detection sensor 4, a day/night identification sensor 5, and a solar sensor. It consists of a battery 6 and a battery 7.

0012 8 is a white light emitter attached to the back side of the sign board 2, and this white light emitter 8 is The battery 7 is used as a power source.

[0013] 9 has punched out characters such as "Stop" or other figures on sign board 2. The light from the white light emitter 8 reaches the front surface of the sign board 2 through the punched part 9. It can be seen from the front. Note that the white light emitter 8 used in the examples is an EL (spark light) Tanley Electric Co., Ltd. trademark).

[0014] The above traffic sign stores electricity in battery 7 using solar cell 6 during the day, and at night. When this happens, the control device 3 is activated by the day/night identification sensor 5, and the vehicle detection sensor 4 is activated. When it detects a car's light, it supplies power to the white light emitter 8 to emit light, and when a car passes by, it emits light. It shuts off the electricity and extinguishes the light.

[0015]

[Effect of the idea]

As described above, the present invention enables signs to emit light when detecting car lights at night. Therefore, it is effective in terms of traffic safety measures, and since it uses solar cells, it is also effective in terms of energy saving measures. is also valid.

[0016] In addition, by using colored light emitters, it is possible to avoid white color, which is legally restricted as a traffic sign. In addition to colored letters, symbols, and figures, signs can be freely illuminated in other colors. I can do it.

Claims (4)

[Scope of utility model registration request] [Claim 1] Draw cut-out characters, symbols, and figures on a sign board, and attach a colored light-emitting body to the back side of the sign board, and when the light of a running vehicle is sensed, the power is turned on, and the colored light-emitting body emits light and punches out. A traffic sign composed of colored characters, symbols, and shapes that are displayed at night. [Claim 2] Solar cells are used to store electricity during the day, and this power is used as a power source for colored light emitters, and the power switch is turned on and off using a signal when the lights of a moving vehicle such as a car or motorcycle are detected. A traffic sign configured to be operated by a controller driven by a vehicle detection sensor that generates a traffic sign. 3. The traffic sign according to claim 1, wherein the colored light emitter is a white light emitter. 4. The traffic sign according to claim 2, wherein the sign is constructed by pasting a colored luminous material alone or in combination on the surface of a sign board.
