Abstract
A light-emitting diode structure with transparent window covering layer of multiple films includes one (or several) first transparent covering layer(s) and one (or several) second covering layer(s), which are formed on the outside of the light-emitting diode chip. The light-emitting diode chip can emit light in more than two wavelengths to increase the transmission of the different wavelengths and the taking out efficiency of the light-emitting diode. The first transparent covering layer(s) and the second covering layer(s) are deposited each on the other on the outside of the light-emitting diode chip. The surface of the light-emitting diode with the covering layers is smooth. The contacting parts of the first transparent covering layer(s) and the second covering layer(s) are connected by a strong adhesive force and the contacting parts of the covering layer and light-emitting diode chip also are connected by a strong adhesive force.
