Description

Safety sign panel of using E / L sheet

The present invention relates to a safety sign using an electroluminescent sheet to protect workers from various hazards such as the workplace and the surrounding environment.

More specifically, it is possible to minimize the occurrence of various safety accidents by clearly notifying the surrounding environment and disasters such as construction sites to workers or passers at daytime as well as at night by the light emitting sheet which emits itself clearly when power is applied. It relates to a safety sign using a light emitting sheet.

In general, in various workplaces such as construction sites or factories, various accidents are constantly occurring due to worker's carelessness, lack of safety education, mistakes of working colleagues, non-wearing safety equipment such as protective equipment, or the environment around the workplace. Due to the physical injuries suffered by the workers themselves, they suffer as well as mental and physical damage to their family and colleagues.

Therefore, in the workplace where there are many risk factors and high incidences of safety accidents, safety signs marked with figures and / or letters are attached to predetermined positions that can be easily identified by the workers, thereby repetitively informing the workers of the surrounding environment and risk factors. At the same time, it is consciously informed to minimize the occurrence of safety accidents.

That is, as shown in Figure 1, when lifting or moving the steel pipe or reinforcement of heavy weight using a crane as an example in the work site, the worker is injured when the lifting object falling of the hanging heavy weight in the crane In order to prevent the worker from entering and leaving under the salvage object, a safety sign with a picture is attached to a predetermined position where the worker can easily identify.

However, as described above, the safety signboards are written with letters and pictures, such as pate, so that the worker is not able to easily identify the safety signs even during the day due to the fading or discoloration of the paint due to the neglected outdoor environment. There will be no more safe signage. As a result, the original function of using the safety signboard is lost, and there is a problem that the safety awareness of the worker is thin and the probability of occurrence of a safety accident increases.

In addition, the construction site works mainly in the outdoor environment where the environment is poor, and when the dust is easily accumulated on the surface of the safety signboard, the sharpness of the safety signboard is degraded. Therefore, the surface of the safety signboard should be periodically cleaned. Aftercare is absolutely required.

In addition, when installing the lighting means for irradiating the safety signage so that the worker or passer-by can easily identify the aforementioned safety signage during the day or at night, the cost of manufacturing the safety signage increases due to the complicated structure of the safety signage. In addition, there is a problem that the maintenance cost increases according to the power consumption.

Accordingly, an object of the present invention is to provide a light emitting sheet that allows an operator to easily identify safety signs such as during the day as well as at night to protect the operator from safety accidents caused by various disasters and the surrounding environment. It is to provide a safety sign used.

Another object of the present invention is to eliminate the need for a separate lighting system, such as a lamp, and greatly reduce the cost and power consumption of manufacturing safety signage due to the simplified structure, the light emitting sheet to minimize the maintenance costs to follow up It is to provide a safety sign using.

Another object of the present invention is to provide a safety sign using a light emitting sheet that can keep the operator clear of safety consciousness even when the safety signboard is installed outdoors in a poor working environment. To provide.

The purpose of the present invention described above, in the safety signage to protect the operator from various hazards and the surrounding environment, such as the workplace, the printed layer except for the text to be displayed, the printed layer around the printed layer, The light emitting sheet which emits light when the power is applied, emits the text, the carbon layer applied to the back surface of the light emitting sheet to supply power to the light emitting sheet, and the power applied to the light emitting sheet is controlled so that the text is emitted. And an inverter configured to have a first state to be retained and a second state in which the text is continuously blinking, and a protective plate formed on the back surface of the printed layer to prevent foreign matter from penetrating from the outside. By providing a safety signboard used.

According to a preferred embodiment, a power source using a solar cell, a storage battery, an A / D converter may be used as the power source.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to be described to be easily implemented by those skilled in the art in order to facilitate understanding of the present invention, This does not mean that the technical scope of the present invention is limited.

As shown in Figure 2 to 4, the safety sign using the light emitting sheet according to the present invention, safety signage, to protect the worker from various hazards and surrounding environment in the construction site or industrial site, etc. It can be applied to signs, various commercial signs.

Therefore, according to a preferred embodiment of the present invention, except for the letter (a), figure (b) to be displayed or the text (1) to combine them, the printed layer (3) is printed around the background (2) And a light emitting sheet 4 that emits light upon application of power and emits text 1; a, b; and a carbon layer 5 that is applied to the bottom of the light emitting sheet 4 to supply power to the light emitting sheet 4 ( a carbon layer) and an inverter 6 for controlling the power applied to the light emitting sheet 4 to have a first state in which the text 1 is kept in a luminous state and a second state in which the text 1 is continuously blinking. and a protective plate 7 formed on the back surface of the printing layer 3 to protect the light emitting sheet 4 and the like from being prevented from penetrating foreign substances such as water and dust from the outside.

At this time, preferably, as the power supply to the above-described light emitting sheet 4, a power source using a solar cell, a storage battery, an A / D converter may be used.

Reference numeral 8 denotes an adapter for converting AC 110 / 220V into DC 12V as a power source applied to the light emitting sheet 4 described above.

Hereinafter, a method of using the safety sign using the light emitting sheet according to the present invention will be described.

As shown in FIG. 4, as an example, safety signs are installed in a workplace such as a construction site having a high frequency of accidents so as to protect the worker or a pedestrian from falling objects. .

In other words, 'Hazard' and 'Falls' are displayed as letters (a) to warn workers or passers-by the dangers and surroundings of the workplace, and the worker wears a 'safety hat' with the symbolism to work after wearing a hard hat. By wearing the safety signboard (b) of the figure (b) of the worn picture it is possible to minimize the occurrence of safety accidents by raising the safety awareness of the worker.
