Abstract
A Christmas LED bulb manufacturing process includes: taking a conductive wire: taking a conductive wire with a preset length, the conductive wire being a Dumet wire or a platinum wire; removing impurities: removing foreign matters and impurities on a surface of the conductive wire; welding a chip: welding and fixing a LED chip to the conductive wire after impurity removal; sealing: after the chip is welded, injecting one of silica gel, resin and silica gel, or a mixture of resin and a high thermal conductivity material into the LED chip to wrap the LED chip; assembling: inserting the sealed LED chip into a glass tube; and performing glass-sealing: melting two ends of the glass tube for sealing and molding.
