LED LIGHTING DEVICE HAVING A PHOSPHOR COMPOSITION |
摘要 |
<p>There is herein described a phosphor composition for converting the light emitted from LED dies. The phosphor composition has an emission dominant wavelength responsive to an excitation dominant wavelength. The phosphor composition includes a first phosphor, a second phosphor and a third phosphor. The phosphor composition has a first weight ratio of the first phosphor and the second phosphor, and a second weight ratio of the second phosphor and the third phosphor. The first and second weight ratios are arranged so that the emission dominant wavelength increases as the excitation dominant wavelength increases.</p> |
