| titleOfInvention | White light-emitting diode |
| abstract | A white light-emitting diode (LED) at least includes a excitation light source and a fluorescent powder, wherein the excitation light source is capable of emitting a light source having a wavelength of 258 to 490nm, and the fluorescent powder is distributed around the excitation light source for receiving the light emitted from the excitation light source. Furthermore, the material of the fluorescent powder is selected from a group consisting of (Ca,Sr,Ba,)8Mg(SiO4)4Cl2: Eu<SP>2+</SP>, Dy<SP>3+</SP>, Mn<SP>3+</SP>. The invented white LED has a higher illumination efficiency and a better color rendering property. |
