JPH1071951A - Signal lamp using light emitting diode - Google Patents

Abstract

PROBLEM TO BE SOLVED: To lengthen the sevice life, simplify maintenance and control, and previously prevent a railroad accident by arranging blue and yellow lamps at a specific rate, and arranging polished glass on a front face of the lamps in order to display a white lamp by using the yellow and the blue lamps of a light emitting diode. SOLUTION: In order to display a white lamp by using yellow lamps 3 and blue lamps 4 of a light emitting diode, the ratio of the blue lamps 4 and the yellow lamps 3 is set at a rate up to 1:3.5 to 1:5.0, and polished glass is arranged on a front face. Since only an electric current half of the yellow lamps can be flowed to the blue lamps, two blue lamps are juxtaposed. When the polished glass 5 is used, the light of an internal electric lamp can be diffused, and colors of blue and yellow are sufficiently mixed, and can be seen as a white lamp even when looked at close range and even when looked from a distance place, and the light is not dispersively looked. Therefore, the service life is lengthened, maintenance and control of a signal lamp can be simplified, safety is enhanced, and a railroad accident can previously be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a railway signal light.

[0002]

2. Description of the Related Art Conventionally, a white light using a nichrome wire has been used. However, in order to extend the life of the device, a light emitting diode has been used and the signal light has been changed to a maintenance-friendly signal light. Diode white light is not available.

[0003]

As described above, there is no white light with a single light emitting diode at present, and the present invention has been developed as an alternative to this, and a white light is displayed by using a light of another color. What you want to do.

[0004]

In order to achieve the above object, a white light is displayed by using a yellow light and a blue light of a light emitting diode, and the ratio of the blue light to the yellow light is 1:
The lamps are installed at a ratio of 3,5 to 1: 5,0, and further, polished glass is provided on the front of these lamps. With such a configuration, a display very close to a conventional white lamp can be obtained. It can be used, has a lifespan more than 10 times longer than that of conventional white lights, simplifies maintenance of signal lights, has high safety, and is equipped with frosted glass. It has the effect of preventing a railway accident from occurring. It should be noted that the ratio of 1: 3, 5 is required for a large-diameter signal light because a large-diameter signal light becomes more visible than a yellow-colored yellow light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail. In order to display a white light by using a yellow light 3 and a blue light 4 of light emitting diodes, the ratio of the blue light 3 to the yellow light 4 is one. :
3,5 to 1: 5,0 are provided, and furthermore, polished glass 5 is provided on the front surface thereof. This will be described in detail with reference to the drawings. The case of a light box with a typical shape will be described.

In a cylindrical light box 1 made of metal, necessary wires 2 and light-emitting diodes such as a yellow light 3 and a blue light 4 are installed, and a polished glass 5 is provided on the front surface thereof.
As shown in FIG. 2, one blue lamp 4 and five yellow lamps 3 constitute one set. This embodiment shows a case where the size of the light box 1 is slightly smaller, and when the size of the light box 1 is larger than this, the ratio of the blue light 4 to the yellow light 3 is 1: 3,5, and the light box 1 is It is divided into four equal parts, and the four sets, each of which is a set of five, are arranged at the positions where they are equally divided into four.
3 is connected as shown in FIG. 3 and A .. is connected to one line and B .. is connected to the other one line. Therefore, in FIG. Even if the line is disconnected, the other one line is wired so as to exert the same effect as almost two lines, and the four hatched blue lights in FIG. The other is a yellow light 3.

The case of FIG. 2 will be described more specifically. As a whole, four blue lamps 4 and twenty yellow lamps 3 are provided, and when current is applied to two lines, all the lamps are turned on. The ratio between the blue light 4 and the yellow light 3 is 1:
5 Next, when the line of A is disconnected, the blue light 4
There are 2 lights, 10 yellow lights, and a ratio of 1: 5.
Similarly, when the line B is disconnected, two blue lights 4 and ten yellow lights 3 are used, and the ratio is 1: 5. In this way, even if one line is disconnected, the other line can serve as a white light.

Of course, various other wiring methods are conceivable, and high-safety wiring should be adopted. The polishing glass 5 may be a flat plate or a convex type, but preferably a convex type. It should be noted that two blue lamps are arranged in parallel because the blue lamp can only pass half the current of the yellow lamp. In addition, by using the polished glass 5, the light of the electric lamp inside is diffused, and the colors of blue and yellow are mixed well, and when viewed from near or far, it can be seen as a white light. Light does not appear separated. By adopting such a configuration, a display very close to that of a conventional white light can be performed, and the life of the signal light is at least ten times longer than that of the conventional white light. It is expensive and has the effect of preventing railway accidents. By the way, when used under the same conditions, the conventional white light has a life of 10,000 hours, and the light emitting diode continues to emit light for 100,000 hours or more.

[0009]

Since the present invention has the above-described structure,
In particular, the use of polished glass on the front makes it clearly identifiable as a white light when viewed from a distance or near, and is very close to the white light conventionally used. A white light can be provided, and further, the life is extremely long as compared with a conventional white light, maintenance and management can be simplified, and a railway accident can be prevented.
