| 摘要 |
A light emitting diode ( 10, 20, 30, 40 ) includes an illuminant element ( 12 ) and a package ( 14, 24, 34, 44 ). The illuminant element defines an optical axis (OO', O<SUB>1</SUB>O<SUB>1</SUB>', O<SUB>2</SUB>O<SUB>2</SUB>', O<SUB>3</SUB>O<SUB>3</SUB>'). The package has a transparent surface ( 141, 241, 341, 441 ) oblique to the optical axis. The illuminant element is disposed inside the package. Light illuminated by the illuminant element emits from the light emitting diode via the transparent surface.
