LED light bulb and manufacturing process thereof

A LED light bulb, comprising:

• a glass shade and a LED bead, the LED bead being encapsulated in the glass shade, the LED bead comprising a first pin, a second pin, a LED illuminant, and a package body, the first pin and the second pin projecting out from a base of the glass shade, wherein
• a first bent segment is formed at a top end of the first pin, and a second bent segment is formed at a top end of the second pin, the first pin forms a structure comprising a first base and a first inclined segment and the second pin forms a structure comprising a second base and a second inclined segment, the first inclined segment being connected between the first base and the first bent segment, the second inclined segment being connected between the second base and the second bent segment, an included angle between the first inclined segment and the first bent segment and an included angle between the second inclined segment and the second bent segment being both acute angles, the first bent segment and the second bent segment being bent in opposite directions perpendicular to a plane defined by the first base and the second base, the first bent segment and the second bent segment being substantially disposed on a first plane to form a mounting platform, the first plane being substantially perpendicular to an axial direction of the glass shade, the first bent segment and the second bent segment are spaced apart on the first plane, and projections of the first and second bent segments overlap in a direction perpendicular to a length direction of the first bent segment;
• the LED illuminant is disposed flatly on the first bent segment and the second bent segment from top to down, the LED illuminant is secured on the mounting platform, wherein the LED illuminant includes an LED chip being disposed on a front side of a substrate, a positive weld joint surface and a negative weld joint surface being provided on a back side of the substrate that faces the first plane and on which the positive weld joint surface and the negative weld joint surface are formed for connection to the first bent segment and the second bent segment, the positive weld joint surface and the negative weld joint surface being spaced apart by an insulative gap, the first bent segment being welded to the positive weld joint surface and the second bent segment being welded to the negative weld joint surface, such that the LED illuminant is supported by the first bent segment and the second bent segment at overlapping projections of the first bent egment and the second bent segment;
• and
• the package body encapsulates the LED illuminant and respective weld joints between the LED illuminant and the first bent segment and between the LED illuminant and the second bent segment.
