Description

Lamp protection cover {GLOBE FOR A LAMP}

The present invention relates to a protective lamp protection lamp, and more particularly, to prepare a protective cover of the indoor and outdoor lighting by separating the two semi-circles, respectively, and then simply by assembling two semi-circles by an appropriate coupling means to be assembled. The present invention relates to a lighting lamp protective cover that can be used.

Public facilities, such as schools and hospitals, are equipped with various types of indoor and outdoor lighting, which are covered by protective covers of glass or polycarbonate. Recently, a protective cover made of polycarbonate which is not easily broken is used instead of a glass protective cover. Conventional representative methods of manufacturing such polycarbonate globes include injection and extrusion blow types, sheet blow types and cold parison types. Among them, in the case of the injection blow type, the sealing parison is formed by injection molding and then surrounded by a blow mold, and is disclosed in detail in Korean Patent No. 171223, filed on October 19, 1998.

In the manufacturing method of this, a neck mold for forming the neck portion of the protective tool is attached, the core mold and the cavity mold are attached, and resin is injected around the core mold to form a parison. Next, after the parison is moved from the cavity mold to the blow mold using the core mold as a support, the blow mold is closed and the air inlet (not shown) provided in the core mold is opened to inject air into the mold. After cooling, the neck mold and blower mold are opened to take out the finished product.

However, in the case of manufacturing a protective lamp cover in this way is cumbersome and time-consuming because of the large number of work processes, resulting in an increase in manufacturing costs. In addition, since the protective cover is made of a single circular body, the molding operation is very difficult, and there is a fear that the overall thickness is uneven because it is molded by injecting air. In particular, in order to integrally form the intermediate part of the circular body smoothly and precisely, there is a problem in that the width of the resin part to be expanded to this part must be strictly set. In addition, in the case of the conventional circular protective cover takes a lot of space at the time of storage, there is a problem that the logistics cost is excessively expended because the quantity that can be loaded during transportation is limited.

An object of the present invention for solving the above problems is to separate the protective cover into the lower and upper hemisphere, respectively, and then molded into a single circular body by using a coupling means formed on the circumferential surface of the lower and upper hemispheres, and thus the workmanship and It is possible to reduce the manufacturing cost and to provide a light protection cover that can be molded easily.

In addition, another object of the present invention is to provide a protective cover, such as the illumination efficiency is increased, and especially the mass production is advantageous because there is no need to strictly set and control the width of the resin portion expanded in a smooth columnar shape compared to the prior art.
