LIGHT EMITTING DIODE INCLUDING A WAVELENGTH CONVERSION MATERIAL AND A DIFFUSION MATERIAL AND MANUFACTURING METHOD THEREOF CAPABLE OF IMPROVING THE UNIFORMITY OF COLOR TEMPERATURE DISTRIBUTION

摘要

PURPOSE: A light emitting diode including a wavelength conversion material and a diffusion material and a manufacturing method thereof are provided to increase a uniform light emission area by scattering and dispersing light from a light emitting diode through a diffusion layer. ;CONSTITUTION: A light emitting diode chip(20) is formed on a base structure(10). A light emitting diode chip includes a first clad layer, a second clad layer, and an active layer. A first material layer(30) is formed on the light emitting diode chip. A first protection layer(22) is formed on the first material layer. A second material layer(40) is formed on the first protection layer.;COPYRIGHT KIPO 2011
