DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display using a xenon flash lamp, and more particularly, to an emergency display,
The visibility function such as a warning display can be effectively exerted.

[0002]

2. Description of the Related Art Conventionally, as a display device of this type, a device using a phosphorescent material has been known. This is achieved by irradiating the phosphorescent material with light such as sunlight or a fluorescent lamp from the outside. To emit light for a certain period of time by the excitation of.

[0003]

However, a display using a phosphorescent material has a problem that its use is limited because light emission of the phosphorescent material disappears in a short time.

In view of the above, the present invention uses an internal light source such as a xenon flash lamp to emit flash light from a condenser lens to provide an emergency display,
It is designed to be applicable to uses such as warning display. In addition, the use of a light emitting diode enhances a complementary visual recognition function.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and a light source and a light-emitting element each comprising a flashable xenon flash lamp are arranged inside a case body. The flash of the light source is improved so as to be emitted from the condenser lens. The luminous body has a complementary function and is composed of a luminous diode. The condensing lens is formed entirely or partially from one or a plurality on the end surface side of the cylindrical shape, and is formed on the entire circumferential surface or on the side surface of the cylindrical shape. It is partially formed from one or a plurality. When an illumination function is required, a self-luminous body made of a fluorescent material and a light storage material may be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the display according to the present invention will be described below with reference to the drawings.

FIGS. 1 (a) and 1 (b) show a display device 1 having a cylindrical shape, and a resin lens, for example, a Fresnel lens or the like, is provided on the entire surface of the case body 2 on the end face side. A condensing lens 3 is provided, and a blinkable light source 4 and a light-emitting body 5 composed of a light-emitting diode are arranged in the case body 2.
It is designed to face. In this case, the condenser lens 3
A coloring filter 5a is provided on the inner surface as necessary. Although the circuit of the light emitting diode is not shown, the light emitting diode is usually a semiconductor diode made of gallium arsenide crystal, and functions as a light source when a voltage is continuously or pulsed. Things. And G
It is known that a-Asno emits infrared light, and Ga-P doped with O ₂ and N ₂ emits red light and green light.

The light source 4 is composed of a xenon flash lamp, a so-called strobe lamp, and is configured to be turned on and off by a drive circuit 7 provided on a circuit board 6. The drive circuit 7 includes a capacitor, a transformer,
It is composed of components such as transistors, and is connected to a driving source 8 such as a dry battery, a rechargeable battery, a battery or an AC power source. The purpose of using dry cells and rechargeable batteries is to make them more portable.

FIG. 2 shows another display 1 in which the same parts as those in FIG. 1A are denoted by the same reference numerals. In the display 1, a case body 2 has a long cylindrical shape, and the condenser lens 3 is formed on a part of an outer cylindrical surface thereof so as to be continuous in a circumferential direction. On the inner surface side of the case body 2, not only the light-emitting body 5 composed of the light-emitting diode but also a self-luminous body 9 such as a fluorescent material or a light-storing material for the purpose of complementing the illumination function. Provided. This self-luminous body 9 can be applied not only to a single application of a fluorescent material and a phosphorescent material, but also to a partial combination of the two or a material obtained by stirring and mixing both powders. These self-luminous bodies 9 may be applied with a fluorescent material by application or sheet sticking, and for example, purple-blue light emission, blue light emission, green light emission, etc. are obtained. Luminescent materials are luminous when exposed to sunlight or fluorescent lamps during the daytime, and even when there is no external light, the luminous material itself emits green light or the like. Formed by In addition, it is also possible to form the sheet-like phosphorescent material by bonding or the like. In order to enhance the excitation function of the luminous material and make it more effective, it is important to shorten the distance between the luminous material and the light source 4 and to improve the utilization rate of the luminous flux.

The thus constructed display 1 of the present invention enables emergency display and warning display by a strong flash from the condenser lens 3 even at night. this is,
This is because it can be used as a substitute for smoke emitting lamps, and can cope with emergency troubles of vehicles and automobiles. The display function is also complemented by the illumination function from the self-luminous body 9.

Note that the condenser lens 3 is shown in FIGS.
In the case of (1), it is provided on the entire surface on one end face side, but it may be provided partially or plurally, or may be formed on both end face sides.

FIGS. 2A and 2B show another display 1.
The same parts as those in FIG. 1A are denoted by the same reference numerals. In the display 1, a case body 2 has a long cylindrical shape, and the condensing lens 3 is formed on an outer cylindrical surface thereof so as to be continuous in a circumferential direction. In addition, three light-emitting members 5 composed of light-emitting diodes on the bottom side of the case body 2 are provided, and the remaining inner surface is provided with:
A self-luminous body 9 is provided. And this self-luminous body 9
Is a transmitting surface 9a made of a transmissive phosphorescent material,
A reflection surface 9b made of a reflection type light storage material is formed. The portion other than the light-emitting body 5 on the inner surface side of the case body 2 may be changed so that a fluorescent material is applied, or a mixed powder of a fluorescent material and a phosphorescent material may be applied. This takes into account, for example, that a red phosphorescent material is complemented with a fluorescent material.

The condenser lens 3 is shown in FIGS. 2 (a) and 2 (b).
In the case of, the annular surface is provided as a part of the annular surface continuous in the circumferential direction. However, one or more annular surfaces may be provided partially, or may be formed over the entire circumferential direction.

[0014]

As described above, according to the present invention, since the display 1 is a combination of the light source 4 capable of blinking with the condenser lens 3 formed in the case body 2, the light source There is an advantage that the emergency display and the warning display can be performed by the strong flash from 5. In addition, a visual recognition function such as a warning color by the light emitting body 5 can be used.
This has the advantage that the function can be supplemented.
