Beschreibung
Zusammenfassung:	The utility model discloses a power type white light emitting diode which comprises a base. A groove is arranged in the middle of the base, a blue LED chip and a red LED chip are fixed in the groove, and the blue LED chip and the red LED chip are packaged in the groove through a fluorescent powder layer. Through the addition of green fluorescent powder into yellow fluorescent powder, the defect that the green light component of an ordinary LED in 500 nm is insufficient is compensated; meanwhile, through the red light compensation of the red light LED chip, compared with an ordinary LED, the utility model improves the color reproduction characteristic within a green light range and a red light range, a luminescent spectrum of the utility model is more similar to a luminescent spectrum of an electric incandescent lamp, and meanwhile, spectra of violet light, ultraviolet light and infrared light are reduced, therefore, the utility model provides a healthy and comfortable light source.
