Description

[Detailed description of the invention] This invention is made of transparent plastic.

It also relates to traffic signs and other signs that use flexible round rod-shaped light guides.

A variety of signs using light guides have recently been studied, compared to conventional signs (two signs) in which nighttime paint is applied to the display surface, and the present invention is one proposal in this regard.

Figure 1 shows the basic configuration of this invention, (1)
(2) is a front plate made of transparent plate glass or plastic; (2) is a round bar-shaped light guide each forming one dot; and (2) is made of transparent plastic.
and has flexibility. And the dot is a character that will be explained later.

It is the smallest unit of a symbol or figure (picture).

One end of the light guide is fixed to the back side of the front plate (1), and the other end is located at the light generating device (3).

That is, the light generating device (3) is composed of a light source (for example, a halogen lamp) (4) and a reflector (RBFLECTOR) (51) that reflects the light emitted from the light source (4), and the light guide ( 2: The other end is the reflector (5
Located at the 1st focal point.

Therefore, when the light source (4) is turned on by the power from the power source (6), the light enters from the other end of the light guide and is connected to one end ζ.

Diagram 2 is an example of a case where two required displays are made under the configuration shown in Diagram 1. Diagram 2 shows a traffic sign.

By the way, in the case of signs ζ2, it may be necessary to change the display content of one sign every time a predetermined period of time has elapsed.

In other words, depending on the temporal conditions of the road, it may be necessary to change the content of the regulations from time to time.

This invention proposes a suitable label for such a case, and Figure 3 is an example thereof.

Figure 3 (2, (11 is the front plate, (2-1) ~
(2-0 is a light guide, (3) is a light generator, (4) is a light source, (5) is a reflector, (6) is a power source, (7-1) ~ (
7-11) is an optical switch, which is selectively controlled by a computer (8) in the middle of each light guide (branched into two). Therefore, the above calculation tjj & (8) selects and controls the above optical switch. σe is a memory in which various display patterns are stored and forms part of the computer (8). The memory contains information on which light switch to select according to multiple contents to be displayed, that is, one character to be displayed, etc.
The contents are read out in association with the signal generated from the timer (9) and processed by a computer to selectively control the optical switch.

In other words, initially, for example, the odd-numbered optical switch is set to 0 (the even-numbered switch is OFF at this time), but after a predetermined period of time, the even-numbered optical switch is set to ON (the odd-numbered switch is OFF at this time). be. Therefore,
Initially, the dots on the light guide corresponding to the odd-numbered light switches are indicated, and the dots on the light guide C2 corresponding to the even-numbered light switches are indicated by the dots (2).

Thereafter, display contents based on selected combinations of optical switches are displayed in the same manner. Therefore, one sign C2 can display a plurality of different display contents.

As described above, according to the present invention, it is possible to display two different display contents after a predetermined period of time has elapsed with one sign, and the range of use of the sign can be expanded.

By the way, as in this invention, the above-mentioned light guide.

Signs that combine a light source and 9 reflectors consume less power than conventional signs that use a light source and 9 display masks (representing the shape of displayed characters, etc.) ζ: Illusory image that tends to occur when electricity is not applied (a phenomenon in which conventional signs appear to be lit due to the reflection of sunlight on the display mask surface, even though the light source is not lit under bright sunlight) This eliminates the need for drivers, etc., and makes it an extremely easy-to-read sign.

Claims (1)

[Claims] One end of a plurality of round rod-shaped light guides made of transparent plastic and having flexibility is placed on one side of a front plate made of transparent sheet glass or plastic. A light switch controlled by a computer storing a plurality of display patterns is provided between one end and the other end of the light guide, and the other end of the light guide is connected to a light source and a reflector. The reflector is located at the focus of the reflector of a light generating device consisting of a light generating device (RW), and the light generated from the light source is reflected by the reflector and enters the light from the other end. 41. The device is configured to guide the incident light to one end of the light, and the computer C2 controls an optical switch every time a predetermined period of time elapses to change the displayed content. .
