The invention discloses a complete LED bulb and a manufacturing method thereof. The complete LED bulb comprises a lamp holder, a bulb shell, a drive assembly, a heat dissipation piece connected between the lamp holder and the bulb shell and a light source assembly connected in the bulb shell. The bulb shell and the heat dissipation piece are connected through secondary injection molding of a secondary injection molding body, and the formed bulb shell and the heat dissipation piece form an integrated complete bulb appearance. The complete LED bulb has the following advantages that the heat dissipation effect is greatly improved, production of complete bulbs with higher power can be achieved, the yield is high, and the automatic production of the whole complete LED bulb is advantageously achieved. 本发明公开了种全泡LED灯及其制作方法，该全泡LED灯包括灯头、泡壳、驱动组件、装接于灯头与泡壳之间的散热件及装接在泡壳中的光源组件，所述泡壳与散热件通过二次注塑体二次注塑成型连接，成型后的泡壳和散热件形成整体的全泡外形。它具有如下优点：散热效果大大提高，可实现更高功率的全泡灯的生产，良品率高，有助于实现全泡LED灯整灯的自动化生产。
