Title: Pre-molded LED light bulb package

Description:
BACKGROUND OF THE INVENTION 
     As shown in  FIG. 1 , after the chip and gold wire are inserted into the chip cup at the top of the conducting bracket of the old LED, the old LED must be moved into the mold and filled with epoxy resin, which will dry and harden gradually to form the light bulb; the light given off by the chip at the top is dispersed through the epoxy resin. As the light bulb is totally of the injection epoxy resin structure, the drying process is time-consuming and inconvenient; plus, the conducting bracket must be immediately moved into the mold for mold injection to form the light bulb after its chip and gold wire are inserted; otherwise, the non-packaged chip and gold wire are prone to absorb particles, dust and moisture in the air, therefore reducing the lighting effect and shortening the service life. 
     SUMMARY OF THE INVENTION 
     The primary purpose of the present invention is to provide a pre-molded LED light bulb package, wherein the chip and the gold wire outside the chip cup at the top of the conducting bracket are covered with epoxy resin to form the oblate spheroid, which is filled with injection PC or ordinary resin to rapidly condense into LED enclosure, therefore significantly reducing the time of the packaging process and increasing the output capacity of mass production. 
     The secondary purpose of the present invention is to provide a pre-molded LED light bulb package, wherein the chip and the gold wire in the chip cup at the top of the conducting bracket are covered with an appropriate quantity of epoxy resin to form the oblate spheroid to generate the internal optical amplified light source effect. 
     Another purpose of the present invention is to provide a pre-molded LED light bulb package, wherein the upper end of the injection PC or ordinary resin enclosure is of the convex or concave structure to generate the special amplified or integrated light source effect whereby the light source is deflected and amplified internally first and then gathered externally.

     DELTAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Please refer to  FIG. 2  through  FIG. 4 . The present invention relates to a pre-molded LED light bulb package with its main improvements being: the chip and surrounding of the gold wire in the chip cup ( 12 ) at the top of the conducting bracket ( 1 ) are covered with an appropriate quantity of epoxy resin colloid in advance, which is baked under the effects of the cohesion of the colloid to naturally form an oblate spheroid ( 2 ); the spheroid ( 2 ) at the top of the conducting bracket is inserted into the mold and then packaged with injection PC or ordinary resin instead of traditional epoxy resin, which will condense rapidly to form the LED enclosure ( 3 ). 
     In one embodiment of the present invention, the special combination in which the chip and gold wire at the chip cup ( 12 ) at the top of the conducting bracket are covered with an appropriate quantity of epoxy resin in advance to form the oblate spheroid permits standardized mass production in advance. In conjunction with the injection PC and ordinary resin injected into the mold to condense rapidly into the LED enclosure ( 3 ), the time of the packaging process can be significantly reduced and the output capacity of mass production can be increased. 
     Please refer to  FIG. 5  through  FIG. 6 ; the structure of the pre-molded epoxy resin oblate spheroid ( 2 ), together with the firm chip and gold wire, generates the internal optical amplified light source effect, and the upper end of the external injection PC or ordinary resin enclosure is of the convex or concave structure to generate the special multiple amplified or integrated light source effect whereby the light source is amplified internally and then gathered externally.
