Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an etching glass according to the present invention, showing the front and back surface features of the etching glass 40.

The etching glass 40 according to FIG. 1 is made of transparent safety-tempered glass which is resistant to high temperature and has an etching part 41 for forming a pattern or characters on the back surface of the body.

It is preferable that the safety tempered glass is made of heat resistant tempered glass which is not burned up to a maximum of 1200 ° C.

The surface of the etching portion 41 of the etching glass 40 is preferably roughly polished so that light is diffused and uniformly diffused.

As described above, the etching part 41 in the etching glass 40 is formed by the fine goldsmelt injection method, and a method of engraving the glass by spraying the fine goldsmay has already been proposed, and a detailed description thereof will be omitted.

2 is a perspective view showing that a non-yellowing paint 42 is applied to the etching part 41 of the etching glass 40. The non-yellowing paint 42 is a polyurethane (PU) (Poly methymethacrylate) series, PBMA (polybutylmethacrylate) series and PS (polystyrene) series having a self-refractive index in a polyester binder, a pigment for color implementation, and the mixture can be coated Based solvents.

The non-yellowing paint (42) is preferably formed of a paint containing a fluorescent material so as to enhance the light-transmitting effect of the LED light source (30).

FIG. 4 is a perspective view showing the non- FIG. 9 is a horizontal cross-sectional view and detailed view of an etch glass 40 coated with a paint or an opaque paint, and FIG. 9 is a schematic view showing an actual arrangement of a finished fire safety guide lamp, Fig. 10 is an actual photograph of a fire safety guiding light which is formed by arranging the LED at the edge portion and is made of a non-yellowing paint and an opaque paints, and visually, unlike a general fire safety guiding light, Can be confirmed.

The pattern or character to be transmitted to the user is engraved on the back surface of the body of the etching glass 40. Since the etched pattern or characters formed on the side of the etched glass 40 form a constant thickness, A sufficient display device effect can be obtained through the etched portion 41 etched on the glass and the non-yellowing paint 42 applied to the inside of the etching portion even if the light source 30 and the light source 30 are not illuminated. The non-yellowing paint 42 that reflects or transmits a part of light exhibits a more clear and stereoscopic effect and has high attention and clarity.

Heat-resistant color glass having the same shape as the groove of the etching part 41 may be used instead of the non-yellowing paint applied to the etching part 41 in the etching glass 40. [

Whether the paint to be coated on the portion 43 outside the etching area is to be a light-transmitting paint or an opaque paint depends on the visual effect. The difference in visual effect is that, as shown in FIGS. 9 and 10, And the difference in transparency of the paint applied to the portion 41 outside the etching area and the portion 43 outside the etching area causes the three-dimensional feeling to be visually felt differently.

It is preferable that the opaque paints are treated with paints which are colored but not transmittable with light.

It is also preferable to use a safety-enhanced glass material resistant to high temperature instead of the etchant glass 40, and a glass printed on the rear surface of the body by a silk screen technique, It has the same clarity as the guide light, but the entire exterior is made of fire-retardant material.
