MANUFACTURING METHOD AND STRUCTURE OF LIGHT-EMITTING DIODE WITH MULTILAYERED OPTICAL LENS

摘要

A manufacturing method and a structure of a light-emitting diode (LED) with a multilayered optical lens are provided. The manufacturing method includes the steps of: providing an LED chip; forming at least one inner protective layer covering the LED chip and its wire connecting points; and forming an outer protective layer covering the inner protective layer. Both the inner and outer protective layers are optical resin layers while the inner protective layer is harder than the outer protective layer. The structure of the LED includes: an LED chip; at least one inner protective layer covering the LED chip and its wire connecting points; and an outer protective layer covering the said inner protective layer. The relatively hard said inner protective layer can resist external force transmitted by the outer protective layer and protect the LED chip and its wire connecting points from damage by the external force.
