Lighting cover and manufacturing method of this cover {GLASS COVER FOR ELECTRIC LIGHTING DEVICE AND MANUFACTURING METHOD THE SAME}

The present invention relates to a cover for a lamp and a method of manufacturing the cover, and more particularly to a cover for a lamp and a method for manufacturing the cover that can further enhance the decorative aesthetics while maintaining optimal illuminance. .

In general, the lamp cover is formed in a predetermined shape by forming a glass or synthetic resin in the lamp body to protect the lamp and to produce a variety of indoor atmosphere due to the indirect lighting effect that transmits the light emitted.

In recent years, the above-mentioned lighting cover is recognized as an important means for determining the atmosphere of the building, and the consumption pattern of the consumer is also determined depending on whether or not to obtain a luxurious interior effect, that is, a form that can meet the demand. By printing various patterns on its own, it is possible to obtain an improved interior effect.

As described above, in the method of forming a pattern on the lamp cover, the uneven parts are integrally formed together in a predetermined pattern shape when the cover is molded, or a predetermined pattern is formed by a physical method using a coloring pigment or a sticker after molding. It is common to do

However, in order to form uneven parts integrally on the surface of the lamp cover manufactured by the above-described conventional method, the manufacturing cost of the mold is excessively consumed, and the indirect lighting effect of the cover is reduced by its morphological characteristics so that the cover is reduced. Not only does it degrade its function, but it also comes with manufacturing limitations to achieve decorative effects.

In addition, when a pattern is attached by a physical method using the coloring pigment or sticker, the expression of texture may not be properly exhibited, and the light transmittance of the structure may be remarkably lowered, so that a satisfactory effect may be expected. It becomes impossible.

In addition, since the conventional lighting lamp cover is formed on the surface of the coloring pigment or film paper by a physical method, the adhesive force of the coloring portion and the adhesive portion gradually decreases over time, causing a portion to fall off the surface of the cover or easily broken. Not only is the effect lowered, but also frequent maintenance is inevitable, which in turn lowers the merchandise and reliability of the product.

In addition, the above-described conventional lamp cover has a limit to express the optimum texture simply because a specific shape of the pattern is formed only in a plane, it is difficult to expect a satisfactory decorative effect.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to provide a cover for a lighting lamp that can further improve the decorative aesthetic while maintaining the optimum illuminance (luminance) and a manufacturing method of the cover To provide.
