Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a color blind person (total blind person,
Traffic lights that can be distinguished also by persons with partial color blindness such as red-green blind, yellow-blue blind, etc.).

[0002]

BACKGROUND OF THE INVENTION The automobile is widely used as a means of daily transportation, business activities, and distribution of trucks and the like in modern times. In order to drive a car, it is necessary to obtain a license, but a color blind person cannot obtain a license because of a low discriminating ability of a signal light.

[0003]

[Problems to be solved by the present invention]
The deprivation of the right to obtain a license is severe for color blind people. In other words, just being a color blind person does not have the right to drive a car that is very convenient for daily traveling, etc., and cannot engage in occupations that use cars, which is unequal.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a traffic signal light that can be identified by color blind persons.

[0005]

The traffic light of the present invention comprises:
The following technical measures were adopted. [Means of Claim 1] A traffic signal lamp lights and displays one of a red lamp, a yellow lamp and a blue lamp, and each of the lamps lights and displays a different shape. The lighting color of the blue lamp includes green, blue-green, in addition to blue.

According to a second aspect of the present invention, in the traffic light of the first aspect, each of the lamps includes a plurality of light emitting diodes,
A holding plate for holding the large number of light emitting diodes,
The shape is illuminated and displayed according to the arrangement of the light emitting diodes.

According to a third aspect of the present invention, in the traffic signal lamp according to the first aspect, each of the lamps includes a light bulb and a reflector disposed behind the light bulb, and has a predetermined shape in front of the light bulb. A shape transmission plate that transmits only light is disposed, and the shape is lit and displayed by light transmitted through the shape transmission plate.

[0008]

Function and Effect of the Invention

[Operation and Effect of Claim 1] The traffic signal light is for lighting and displaying any of a red lamp, a yellow lamp, and a blue lamp. With this arrangement, it is possible to identify which lamp is on, not only for a person with normal color vision but also for a color blind person. By using such a traffic light, even a color blind person can identify which lamp is lit, and thus can learn a license.

According to the second aspect of the present invention, the traffic light of the second aspect turns on a selected lamp by turning on a large number of light emitting diodes held by a holding plate without using a reflecting mirror. The selected lamp illuminates and displays a predetermined shape. In this way, because there is no reflector,
Even if the solar light hits, there is no problem that a lamp that is not turned on appears to be turned on. In the morning and evening, even if the lamp hits the lamp, it is easy to visually recognize which lamp is turned on. In addition, the power consumption of a large number of light emitting diodes can be lower than the power consumption of a light bulb used in a traffic signal light so far, so that the power consumption of the traffic signal light can be reduced.

[Action and Effect of Claim 3] The traffic signal light of claim 3 is the same as the traffic signal light that has been adopted so far.
It is only necessary to add a shape transmission plate. That is, since it can be dealt with simply by adding a shape transmission plate that allows only light of a predetermined shape to pass in front of the light bulb in the conventional traffic signal lights, the present invention can be implemented without a large increase in cost.

BEST MODE FOR CARRYING OUT THE INVENTION

[First Embodiment] FIGS. 1 and 2 show a first embodiment of the present invention.
FIG. 1 is a front view of a traffic light, and FIG.
Is a sectional view of a traffic light. As shown in FIG. 1, the traffic light 1 includes a single signal box 2 in which a red lamp R, a yellow lamp Y, and a blue lamp B are arranged. Each lamp R,
As shown in FIG. 2, Y and B are respectively provided in three holes 3 arranged in a row on the front plate of the signal box 2, and an eave 4 for blocking sunlight is attached to the front surface of each hole 3. Have been.

Each of the lamps R, Y and B has a holding plate 5 attached inside the hole 3 of the signal box 2 and a lens 6 attached to the front of the hole 3. The holding plate 5
A large number of light-emitting diodes 7 are held on the front surface, and the lighting state of these many light-emitting diodes 7 is controlled by energization control similar to that of a conventional bulb. Further, the front surface (the surface on the lens 6 side) of the holding plate 5 is provided in black, which easily absorbs light.

Each of the lamps R, Y and B displays different shapes depending on the arrangement of a large number of light emitting diodes 7. Specifically, as shown in FIG. 1, when the red lamp R is turned on, the red lamp R visually displays “x shape” representing “stop”, as shown in FIG. Further, when the yellow lamp Y is turned on, the yellow lamp Y visually displays a “△” indicating “caution” due to the arrangement of the many light emitting diodes 7. Further, the blue lamp B is arranged by a large number of light emitting diodes 7,
When lit, a “視 覚” representing “advance” is visually displayed.

The traffic signal light 1 lights one of a red lamp, a yellow lamp, and a blue lamp.
Each of the red, yellow, and blue lamps lights and displays a different shape such as x, ×, and と 同時 に simultaneously with the color display. For this reason, it is possible to identify which lamp is on, not only for a person with normal color vision but also for a color blind person. In this way, even a color blind person can identify which lamp is lit by the lighting display of the shape, and thus can learn a license.

Further, since the traffic signal light 1 of this embodiment does not have a reflecting mirror, the lamps R, Y, B which are not lit even in the position where the sun rays hit the lamps R, Y, B in the early morning or at sunset. There is no malfunction that appears to be lit. Furthermore, since the power consumption of the large number of light emitting diodes 7 can be lower than the power consumption of the bulb used in the ordinary traffic light, the power consumption of the traffic light 1 can be reduced.

Further, the traffic light used so far can be replaced with the traffic light 1 of the present invention simply by replacing the bulb and the reflector in the conventional traffic light with the holding plate 5 holding a large number of light emitting diodes 7. Can be changed. In other words, the traffic light can be changed to a traffic light that can be recognized by a color blind person at a low cost without having to completely replace the traffic light.

In the first embodiment, an example in which a normal LED is used is shown as an example of the light emitting diode 7, but a super LED may be used. This Super LE
D generates about twice the luminance with the same power consumption as compared with a normal LED. For this reason, the number of super LEDs used for each of the lamps R, Y, B can be reduced to half the number of ordinary LEDs. As a result, the normal LED
And only half of the power consumption is required, and the power generated by the traffic light 1 can be further reduced.

FIG. 3 is a sectional view of a traffic light according to a second embodiment. In the above-described embodiment, the traffic signal light 1 is provided by adding a shape transmission plate 10 that allows only light of a predetermined shape to the traffic signal light used so far. The traffic signal lights that have been used so far are the bulb 11,
A reflector 12 disposed behind the light bulb 11;
1 and a lens 6 disposed in front of the
The shape transmission plate 10 is arranged in front of a light bulb 11.

Although the shape transmitting plate 10 of this embodiment is shown as being disposed inside the lens 6, it is provided by coating the inner surface or outer surface of the lens 6, or is attached to the inner surface or outer surface of the lens 6. May be provided. As described above, since the traffic signal light which has been used so far is used as it is, it is possible to change to a traffic light which can be recognized by a color blind person at a low cost.
