This invention relates to an encapsulating method for sealed and water-proof LED, comprising the following steps: separately weld two leads or three leads onto the two pins of the LED; molding by mould and used for installing the holder of LED; put the LED with lead or various types of ornaments into the holder; buckle the holder; weld the periphery of the buckled holder by ultrasonic machine to form a sealed luminescent light. By means of welding the lead of the luminotron first, putting it into the holder later, and finally sealing it by ultrasonic machine, it can increase the up-to-standard rate and reduce the rejections on the premise of ensuring the sealing effect. |
