TRANSPARENT LIGHT EMITTING DIODES |
| 摘要 |
A transparent light emitting diode (LED) includes a plurality of III-nitride layers, including an active region that emits light, wherein all of the layers except for the active region are transparent for an emission wavelength of the light, such that the light is extracted effectively through all of the layers and in multiple directions through the layers. Moreover, the surface of one or more of the III-nitride layers may be roughened, textured, patterned or shaped to enhance light extraction. |

1. A light emitting device, comprising:
a lead frame having a transparent plate; and a light emitting diode (LED) chip, placed on or above the transparent plate in the lead frame, emitting light through at least front and back sides of the LED chip; wherein the transparent plate in the lead frame allows the light emitted from the LED chip to be extracted out of the LED chip from the front or back side of the LED chip. |
