| titleOfInvention | A kind of white LED light source |
| abstract | The present invention relates to a kind of white LED light source, the mixed fluorescent powder comprising metallic reflection cup, be arranged on the blue-light LED chip bottom metallic reflection cup and be placed in above blue-light LED chip, mixed fluorescent powder is made up of yellowish green fluorescent powder and red fluorescence powder.The present invention is using blue-light LED chip as excitaton source, combine by selecting the red fluorescence powder of the yellowish green fluorescent powder of the rare earth aluminate substrate of specular removal and alkaline-earth silicate matrix, while significantly promoting color rendering index, obtain higher light extraction efficiency, thus realize the white light of specular removal high color rendering index (CRI), meet the technical requirement of general illumination. |
