A glass material and a spherical glass encapsulation process for LEDs were developed. An LED encapsulated by the spherical glass exhibits high directional characteristic and emits collimated lights. The spherical glass encapsulated LEDs are suitable for light sources for displays such as portable projection systems and LCD back lights.
