The present invention relates to a manufacturing method and a structure of a night glow glass, and more particularly to a manufacturing method and a structure of a night glow glass applied in a table lamp, a garden lamp and other illumination devices or various different designs with a night glow effect.
In general, conventional lamps or illumination devices come with a transparent lamp house installed at the exterior of a light emitting unit. In addition to the function of protecting the light emitting unit, the lamp house also provides various changes to give a dazzling effect for the lights produced by the light emitting units through different patterns, colors, pictures, and sandblasting skills which are applied to the surface of the lamp house to improve the quality of the lamps or the illumination devices. However, the method for a conventional glass lamp house to provide a luminescent effect is to heat and soften a glass blank first, and then place the softened glass blank on a blowing device to blow the glass blank into a glass lamp house directly, and then adhere a luminescent material (or a night glow material) onto the glass blank to combine the luminescent material onto a surface of the glass lamp house. The luminescent material combined with the surface of the glass lamp house is deteriorated or faded easily due to its contact with external air and moisture, or scratched during the manufacturing process or after the finished good is manufactured. As a result, the effect and the expiration date of the luminescent material as well as the quality of the glass lamp house will be affected adversely.
In view of the foregoing shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally invented a manufacturing method of a night glow glass to extend the expiration date of the luminescent material and maintain a reliable quality.
Therefore, the primary objective of the present invention is to provide a manufacturing method and a structure of a night glow glass. With a special manufacturing procedure of the night glow glass, a luminescent effect is provided in a glass wall of the night glow glass to give a special visual effect, and the night glow glass with the reliable quality can be applied extensively in various different lamps or illumination devices.
To achieve the foregoing objective, the present invention provides a manufacturing method of a night glow glass, and the manufacturing method comprises the steps of: manufacturing a small glass frit by heating and softening a glass blank; combining a luminescent material by adhering a luminescent material on a surface of the small glass frit, and heating to melt the luminescent material and combine the luminescent material with the surface of the small glass frit; manufacturing a large glass frit by adding a glass blank to a surface of the small glass frit that is combined with the luminescent material, and then covering the luminescent material to form a large glass frit; and shaping a night glow glass by adjusting the hardness of the melted large glass frit, and shaping the large glass frit to form a night glow glass, wherein a layer of luminescent material is melted in a glass wall, and the luminescent material is wrapped into the glass wall to maintain its luminescent effect and prevent deteriorations or color fades.
To make it easier for our examiner to understand the purposes, characteristics and effects of the present invention, preferred embodiments together with related drawings are used for the detailed description of the present invention as follows:
With reference to
(a) Manufacturing a small glass frit by heating and softening a specific quantity of glass blank as shown in
(b) Combining a luminescent material by adhering a luminescent material 13 (or a luminescent powder) onto the whole or a part of a surface of the small glass frit 12 as shown in
(c) Manufacturing a large glass frit by adding the heated and softened glass blank to a surface of the small glass frit 12 that is combined with the luminescent material 13 and spots as shown in
(d) Blowing to form a night glow glass by heating continuously to adjust the softness of the melted large glass frit 14 as shown in
(e) Annealing by returning the finished goods of the night glow glass 10 into a furnace and heating to a specific temperature, and cooling the night glow glass 10 slowly to eliminate the stress produced during the glass manufacturing process and prevent a crack of the glass.
However, the foregoing steps of manufacturing the night glow glass are the main technical characteristics of the invention, but other methods can be used or added to the procedure as needed. For instance, the large glass frit 14 can be heated and softened before it is blown into a night glow glass 10, and then the large glass frit 14 is placed into a thread cutter (not shown in the figure) and turned continuously, such that the luminescent material 13 and the spots are twisted to achieve the effect of forming a spiral distribution on the surface of the large glass frit 14 (as shown in
A night glow glass 10 manufactured by the aforementioned manufacturing method has a transparent property and allows lights to pass through and to be refracted. The night glow glass 10 has a glass wall containing a layer of melted luminescent material 13 and spots, and the spots are distributed spirally on the glass wall of the night glow glass 10, so that a cold light can be emitted from the luminescent material 13 of the night glow glass 10 in nighttime. Particularly for applications in various different lamps or illumination devices, the luminescent material 13 can absorb the light of a light emitting unit (such as a bulb or a light emitting diode, LED) for maintaining the luminescent effect all the time. The luminescent material 13 and spots are formed in the glass wall of the night glow glass 10 and isolated from external air or moisture, so as to assure the color quality and the luminescent effect and prevent the luminescent material 13 and the spots from being scratched and falling off effectively. Obviously, the present invention has a significant improvement over the prior art.
In the night glow glass 10 assembled as a lamp in accordance with the present invention, the shape can be changed as needed to fit different applications. In
