Description

EL cable (EL (Electro Luminescence) CABLE}

The present invention relates to an escape route for subway, shipyard, coal mine tunnel, tunnel, cave emergency guide light, fire and power failure of buildings and underground structures, and 119 light lines for rescue workers to escape from a fire filled scene (Electro Luminescence) CABLE. More specifically, the present invention relates to an EL (Electro Luminescence) CABLE, which is used for position indication and confirmation, backlight of an LCD, thin plate of an advanced wristwatch, ) Is linearly coated and cured to increase the tensile strength, physical strength, and durability of the EL cable so as to enhance the function of the display and confirmation, as well as to enhance the optical performance of the EL cable will be.

In general, EL (Electro Luminescence) refers to luminescence emitted by electricity. This phenomenon is called luminescence, in which light is radiated by energy other than heat. In particular, it is also called electric poles minnesons that cause light by applying an electric field.

The EL lamp using such an EL has an advantage of being an ideal planar light source of a thin plate shape. The EL lamp is a thin phosphor light emitting layer having a thickness of about 20 탆 by dispersing a special phosphor of a sulfur- It is inserted between parallel electrodes and driven by alternating current. The reason for making one side transparent is to emit the copied light.

There are three types of EL lamps currently on the market.

1. A glass-plastic type EL lamp having a structure in which a transparent electrode is mounted on a glass substrate, a phosphor is hardened with a plastic binder to form a thin-film light-emitting layer, and aluminum is vapor-deposited thereon to form a metal plate electrode.

2. A ceramics type EL lamp in which a white enamel is coated on an iron substrate, and an enamel foot and a layer are formed thereon and a transparent electrode is further added.

3. Flexible plastic EL lamp made by wrapping an aluminum foil on a plastic film, making a light emitting layer hardened with a plastic binder thereon, and then repeatedly layering an electrically conductive glass paper.

The above-mentioned EL lamps all have a thickness of 0.5 to 5 mm, a length of about 40 cm, and a power source frequency of 50 to 60 Hz, 500 Hz, and 2000 Hz, and 200 V and 50 Hz are only 20 lux (lx) It is difficult to use it as a general lighting, so it is used for a somewhat dark place indication, a mood illumination, a luminosity light of the instrument panel, a night vision lamp, a footstep.

The emission color of the EL lamp differs depending on the composition of the phosphor, but blue, green, and orange are primary colors.

As described above, the conventional EL lamp, which is currently widely used, is formed as a relatively thin thin plate, and is attached in a tape form.

Therefore, since the conventional EL lamp as described above is formed in the form of a thin plate, it has a weak end which is weak in tensile strength, durability, and does not have a three-dimensional effect in the form of a thin plate.

In order to solve the above problems, the applicant of the present application filed a patent application No. 30-0361892 (hereinafter referred to as "prior art") (hereinafter referred to as "prior art"), A luminescent material comprising a core wire made of a good soft synthetic resin material, a luminescent material coated on a copper wire to which the AC electrode is applied, an inner lining surrounding the same and a luminescent material, a light transmitting body having good permeability and coated with a color layer on its outer surface, Core wire, luminescent material, outer shell covered to wrap the light carrier, and connecting jack for end waterproof, explosion proof and extension.

There is a problem in that the light emitting material and the light transmitting body are spirally wound around the outer periphery of the core wire so that the light emitting material and the light transmitting body can not be clearly emitted when the light is diverted through the outer shell. That is, when the light is transmitted to the light transmitting body, the light does not have directivity so that it is directed toward the outer shell, and the light is scattered in the inner shell to scatter.
