ILLUMINATION DEVICE HAVING DUAL-EMITTING LIGHT EMITTING DIODE (LED) DIE STRUCTURES |
| 摘要 |
An illumination device has a dual-emitting LED die structure in which a first p-n diode structure emits primary light having a peak at a first wavelength, and a second p-n diode structure emits primary light having a peak at a second wavelength that is longer than the first wavelength. A phosphor medium is positioned to be stimulated by the primary light of the dual-emitting LED die structure, and in response emits secondary, wavelength converted light, thereby contributing to a combined white illumination. Other embodiments are also described and claimed. |

1. An illumination device comprising:
a dual-emitting, light emitting diode (LED) die structure having
a first diode structure that is to emit primary light having a peak at a first wavelength, anda second diode structure that is to emit primary light having a peak at a second wavelength that is longer than the first wavelength; and a phosphor medium positioned so as to be stimulated by the primary light of the dual emitting LED die structure and in response emit secondary, wavelength-converted light. |
