摘要: An LED and method for increasing the reliability of LEDs are provided. The LED contains a semiconductor die, a reflector, and a glass capping structure. The glass structure may be solid or formed from multiple layers of uniform or varying dimensions. The glass structure is coated with a phosphor that emits light of a different wavelength than the die. The phosphor is disposed between adjacent layers if the glass structure has multiple layers. The die is disposed in a cavity of the reflector. The cavity may be evacuated or filled with a transparent material.
