Abstract
An LED decorative light bulb and its manufacturing method are disclosed. The LED decorative light bulb has a frame with a negative pole and a positive pole separate from each other. After first copperplating, first nickeling, second copperplating, and second nickeling processes, a crystalplate is melted on the top of the negative pole and a lead extending therefrom is molten on the positive pole. The frame is then covered by epoxy resin and the Decorative light bulb is formed. The LED decorative light bulb is able to be installed in a conventional base which is then fitted in a conventional bulbholder. The crystalplate is higher than the upper edge of the base so that its light is not obscured by the upper edge.
