Abstract

PROBLEM TO BE SOLVED: To easily attract attention, and to enhance visivility over a large distance, by providing two kinds of luminous display means having a light emitting diode and a xenon lamp as light sources. SOLUTION: Flash patterns comprising light from the first four luminous display means 11 neighboringly arranged with a large number of light emitting diodes 17 and light from the second two luminous display means 21 having one xenon lamp 28 respectively are diversified, and sufficient attention is called thereby by lights different in brightness. Even when stains are deposited to deteriorate light transmittances of transparent cover bodies 27 for covering resin lenses of the diodes 17 and the xenon lamps 28, high brightness of flashes emitted from the xenon lamps 28 facilitates visivility in a disant view. Since a light reflecting means 31 reflects a headlight of an automobile or the like to be made visible, a function for a mark is maintained to secure safety even when a trouble that two kinds of the luminous display means 11, 21 are not luminous at the same time is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign device which is temporarily placed on a road for warning, guidance, advertisement, or the like, or is temporarily or permanently attached to a building or a structure.

[0002]

2. Description of the Related Art Signs used to prevent vehicles and people from entering construction sites at roads, buildings, and other construction sites to measure safety, and signs to notify the existence of various facilities, etc. What is installed in the office or required at night is provided with a light emitting display means using an incandescent lamp or a light emitting diode as a light source.

A light emitting diode as a light source is widely used in place of an incandescent light bulb because a dry cell can be used as a power source, and since it generates a very small amount of heat and has a long life. On the other hand, since light emitting diodes have low luminous intensity and narrow light distribution characteristics, those sealed in a resin lens are further arranged inside a light transmitting plate having a light diffusing function, or a large number of light emitting diodes are arranged close in an exposed state. In this way, it can be seen from a wide distance.

As one example, Japanese Utility Model Application Laid-Open No. Sho 62-143708 discloses that a large number of light emitting diodes are housed in a single case so that a large luminous intensity can be obtained, and a large number of the light emitting diodes are arranged as required light emitting display means. It is indicated in the gazette.

[0005]

The light-emitting display means using the light-emitting diode as a light source is kept lit or blinks repeatedly in a predetermined pattern, but it is unavoidable that both are monotonous. However, there is an unsatisfactory part of the sign's original function of giving a stimulus that evokes sufficient attention.

Further, since the sign device provided with the light emitting display means is installed outdoors in an environment exposed to the wind and rain, dirt adheres to the light transmitting plate and the resin lens to lower the light transmittance, and the light transmitting plate and the resin lens are reduced in nature. In addition, there is a problem that the light emitted from the light emitting diode having a low luminous intensity is blocked to make it difficult to visually recognize the light from a distant place. Therefore, frequent cleaning is troublesome.

According to the present invention, a conventional light-emitting display device is provided by adding a light-emitting display device for facilitating attention and facilitating visual recognition from a distance to a sign device having a light-emitting display device using a light-emitting diode as a light source. It is intended to solve the problems that the emitted light pattern is monotonous, so that sufficient attention is unlikely to be called for, and that it is easy to make it difficult to see from a distance due to the adhesion of dirt.

[0008]

As a means for solving the above-mentioned problems, the present invention comprises two kinds of light-emitting display means using at least one light-emitting diode and at least one xenon lamp as light sources. .

A xenon lamp is known as a lamp that emits a flash of high brightness and close to natural daylight. Since it emits strong light that cannot be obtained with a light emitting diode, it is easy to call attention and dirt adheres to the lamp surface. It can be easily recognized even from a distance. In addition, since a flash is emitted by discharging the charge stored in the capacitor, the power consumption is small, and the light emitting interval can be shortened without shortening the life of the battery by using a dry battery as a power supply. In addition, when one fails, the other emits light so that the labeling function can be maintained.

Further, as another means, the present invention includes a light reflecting means in addition to two kinds of light emitting display means using at least one light emitting diode and at least one xenon lamp as a light source.

The light reflecting means reflects the light of a headlight of an automobile or the like to make it visible, and provides safety when both the light emitting diode and the xenon lamp stop emitting light due to the exhaustion of the dry battery or the failure of the control circuit. It is useful as an alternative means of ensuring performance.
