Abstract
Disclosed are a color converting element and a method for manufacturing the color converting element. The disclosed color converting element includes: first wavelength conversion cells spaced apart from one another; and second wavelength conversion cells arranged among the first wavelength conversion cells. The first and second wavelength conversion cells are made of a material containing glass. The color converting element of the disclosed technology is configured in that color converting cells having different color converting characteristics are periodically arranged, when the color converting element is applied to a color converting glass material which may improve thermal and chemical durability of white LEDs, thus minimizing the degradation of efficiency or luminance caused by an interaction between color converting phosphors or active ions and allowing for ease of adjustment of color rendering index.
