GLASS SEALANT COATING METHOD AND GLASS SEALANT COATING DEVICE FOR LIGHT-EMITTING DIODE

摘要

A glass sealant coating device for a light-emitting diode is disclosed. The sealant coating device comprises: a syringe comprising a sealant chamber and a sealant nozzle; a sealant pressing unit for providing a discharge pressure of a glass sealant through the sealant nozzle; and a sealant heating unit which is mounted around the syringe such that a discharge temperature of the glass sealant is maintained above a transition temperature and below a melting temperature. Accordingly, the light-emitting efficiency of a light-emitting diode is increased, the thermal stability of the light-emitting diode is increased, a nozzle clogging phenomenon or the air bubbles which may be generated during coating can be prevented, and the generated air bubbles can be easily removed, by using the properties of the glass sealant.
