摘要 |
The present invention relates to an optical converter and a manufacturing method thereof and a light emitting diode. An optical converter for a light emitting diode includes two substrates, in which, a annular first cavity wall is arranged between the two substrates, and an airtight space filled with an optical conversion substance is surrounded by the first cavity wall and the two substrates. The invention implements the encapsulation and manufacturing of the optical conversion substance for the LED. The structure and the manufacturing method according to the invention can be utilized to encapsulate an active optical conversion substance in the optical converter while avoiding the active optical conversion substance reacting to other active substance, e.g., oxygen, during manufacturing. Furthermore, the optical conversion substance is encapsulated with wafer level chip size packaging to thereby improve the efficiency of manufacturing the optical converter and reduce the cost.
