| 摘要 |
The present invention provides a low-cost light-emitting diode having little irregular color. A light-emitting diode converts light of a first light emission wavelength emitted from an LED as a primary light emission source into light of a second light emission wavelength, using one or a few kinds of phosphor materials. A thin film mainly made of a phosphor material is applied to a light extracting surface of the LED as the primary light emission source, thereby converting a wavelength and emitting light of the secondary light emission wavelength.
