摘要
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. This glass encapsulated LEDs are potent for light sources for displays such as portable projection systems and LCD back lights. (C)2008 The Ceramic Society of Japan. All rights reserved.
