FIG. 5 is a shade diagram illustrating the state of the shaded line 4 appearing on the surface of the vehicle body 1. FIG. 5 is a view of the vehicle body 1 in which the fusing portion 3 is formed when the reflecting tool is fixed to the vehicle body 1 and then emits light. Each shaded diagram illustrating the state of the shaded line 4 appearing on the surface is shown.

As shown in the drawings, the reflection tool for the restoration of the vehicle body depression according to the present invention, the body portion (R) attached with a thin-film electroluminescent lamp (EL lamp) (EL), It consists of a close fitting fixture 40 for attaching and detaching the main body portion (R) at any position on the surface of the vehicle body (1).

The main body part R is formed of a substrate 10 having a predetermined thickness and each aluminum electrode 24 and 25 in a stripe form that is repeatedly formed at a predetermined interval on the back surface which is seated on and in contact with the substrate 10. Deposition is performed to form shaded electrode lines 27 through which the respective aluminum electrodes 24 and 25 themselves can selectively transmit the light emitted toward the front surface thereof, and then to the outside from each of the aluminum electrodes 24 and 25. The wire 26 to which power can be applied is made of a thin film type electroluminescent lamp 20 drawn out.

Here, electroluminescence (EL) refers to a phenomenon in which light is emitted when a strong electric field is applied to a solid. The cause of light emission is that free electrons accelerated by an electric field exist in a light emitting material. This is because an electron of a specific impurity (active agent), which is a light emitting center, is excited and emits energy when it returns to the original state. The use of such a light emitting principle is an EL element, and is used for a display such as a computer screen, an optical amplifier, and the like, and other researches on the application in the television field have been conducted.

The EL element is a light emitting body using an electroluminescent principle, and is formed by attaching electrodes to both surfaces of a light emitting layer (fluorescent layer) molded into a plate shape. The light emitting layer is a solidified light emitting material such as powdered zinc sulfide (ZnS), and has a plastic type and a ceramic type. One of the electrodes may be a metal, but the other uses a transparent electrode to emit light to the outside.

The EL lamp 20 applied to the present invention is formed by forming a thin film of about 10 μm by mixing the fluorescent layer 21 with a dielectric and placing it between a transparent electrode and a capacitor. The EL lamp 20 emits fluorescent light when an AC voltage is applied. .

That is, the electroluminescent lamp 20 applied to the present invention includes a fluorescent layer 21 coated with a zinc sulfide-based special phosphor, and stripes formed repeatedly on the rear surface of the fluorescent layer 21 at predetermined intervals. A pair of aluminum electrodes 24 and 25 that are formed in a vapor deposition form and anodized with the insulating band 23 interposed therebetween, and each of the aluminum electrodes 24 and 25 toward the front surface of the fluorescent layer 21. A stripe-shaped shaded electrode line 27 and wires 26 drawn from the aluminum electrodes 24 and 25 so as to apply a voltage between the aluminum electrodes 24 and 25; The light emitted from the fluorescent layer 21 is transmitted as well as the transparent protective film 22 formed in close contact with the entire surface of the fluorescent layer 21 to protect the fluorescent layer 21.

2 and 3, the shaded electrode lines 27 are arranged at equal intervals while maintaining a line width of a predetermined width.

On the other hand, the substrate 10 is made of a semi-transparent material so that the light of the electroluminescent lamp 20 can be reflected to the front side without scattering, it can be made of glass or acrylic plate.

In some cases, as illustrated in FIGS. 2 and 3, a transparent having a predetermined thickness overlaid on the front surface of the electroluminescent lamp 20 to more firmly protect the electroluminescent lamp 20. The plate 30 may be further provided.

As the coupling structure between the substrate 10 and the transparent plate 30, holes are formed at respective corresponding positions, and then the clamping screw 32 is adopted. However, in addition to the screw fastening method, it is also possible to bond using an adhesive, and any other bonding method may be used.

In addition, the close contact fixture 40 is a flexible wire that can be bent freely so as to hold the main body portion (R) and to be installed in a direction that is easy to work on the surface of the vehicle body 1 or the like to observe the surface curvature A gooseneck 41 is provided, and the close fixture 40 is coupled to an end of the flexible wire 41 so as to be fixed to the surface of the vehicle body 1.

In the support of the main body portion R of the present invention, the main body portion R is reduced in weight, so that only one fastening fixture 40 including the flexible wire 41 is sufficient. Therefore, since the operator can be adjusted to various angles by bending only one flexible wire 41 in any desired direction, work convenience can be significantly improved.

Here, although the various embodiments are possible as the tight fixture 40, it is preferable to apply a permanent magnet, the adsorption plate, etc., because it is a simple structure.

A method of determining the degree of curvature of the surface of the vehicle body 1 by the shaded line 4 which appears when the reflective tool of the present invention having the structure as described above is applied will be described with reference to FIGS. 4 and 5. Is as follows.

As mentioned above, FIG. 4 shows the state of the shaded line 4 appearing on the surface of the vehicle body 1 in which the depression 2 is formed when the reflective tool is fixed to the vehicle body 1 and then emits light. That is, since the shape of the shaded line 4 is projected convexly deformed upward and downward at the position according to the change in the surface curvature of the depression 2 position, the sheet metal can be easily beaten by tapping it from the inside of the vehicle body 1. Restoration can be done.

On the contrary, FIG. 5 shows the state of the shaded line 4 appearing on the surface of the vehicle body 1 in which the fusing portion 3 is formed when the reflective tool is fixed to the vehicle body 1 and then emits light. That is, in this case, the shape of the shaded line 4 is concave and deformed upwards and downwards at the position according to the change in the surface curvature at the position of the fusion part 3, so that this part is knocked out from the outside of the vehicle body 1. If you unfold it, you can easily restore the sheet metal.

On the other hand, Figure 6 and Figure 7 shows the structure of the electroluminescent lamp 20 according to another embodiment applied to the reflective tool for the restoration of the vehicle body depression of the subject innovation, Figure 6 is the electroluminescent lamp 20 7 is a surface of the vehicle body 1 in which the depression 2 and the fusion unit 3 are formed when the reflective tool to which the electroluminescent lamp 20 of FIG. 6 is applied to the vehicle body 1 and then emits light is emitted. Each shaded diagram shows the state of the shaded lines shown in.

As shown in the figure, the shaded electrode line 27 of the electroluminescent lamp 20 according to another embodiment of the present invention is a small acute angle from the surface of the vehicle body 1, such as the operator's observation angle In order to easily measure the shadow line 5 projected on the surface, the thickness of each line is formed differently, and each shaded electrode line 27 having a differential width is arranged at equal intervals.

The present invention illustrates a structure in which the line thickness of the shaded electrode line 27 is gradually tapered downward, and the change of the shaded line 5 according to the surface shape of the recessed portion 2 and the fusion portion 3 is previously described. As described.

The present invention can be applied to the sheet metal work as well as the body of the door, bonnet, and the like will be more useful.

As described above, the reflective tool for restoring and repairing the body recessed part of the present invention is light and installed by accommodating a very thin sheet-type electroluminescent lamp inside to form a thin-film lightweight type structure having an integrated lighting device. It is very easy to use and economical as it has semi-permanent life compared to previous separate lighting devices that use fluorescent lamps with short lifespan. The change in the shaded lines projected on the surface of the vehicle body by the shaded electrode lines formed on the front surface of the vehicle body is clearly shown, thereby exhibiting various advantages to quickly and accurately determine whether the surface is distorted.

In particular, the reflective tool for the restoration of the body recessed part of the present invention is deposited in the form of stripes in which the electrodes of the electroluminescent lamp are repeatedly formed at predetermined intervals, and thus are applied as a shading line forming means for selectively transmitting light, thereby further reducing the weight of the thin film. Therefore, the main body itself is further lighter in supporting the main body part, so that only one fastening fixture including the flexible wire may be provided, and one flexible wire can be freely bent in an arbitrary direction desired by the operator when using it. Since it is possible to adjust the various angles by only to have the advantage that the work convenience can be significantly improved.

The present invention has been described with reference to the embodiments shown in the accompanying drawings, which may be regarded as exemplary, and those skilled in the art may conceive various modifications and equivalent embodiments therefrom.
