| titleOfInvention | LED unit and its application |
| abstract | The invention discloses an LED unit and its application. The LED unit includes an LED chip, a first phosphor powder and a second phosphor powder. The peak wavelength of the LED chip is 455nm-460nm, the excitation wavelength of the first phosphor powder is 520nm-545nm, and the excitation wavelength of the second phosphor powder is 620nm-650nm , the first phosphor powder and the second phosphor powder are located in the light-emitting direction of the LED chip. The LED unit according to the embodiment of the present invention has at least the following beneficial effects: the peak wavelength band of the blue LED chip used in the embodiment of the present invention is 455-460 nm, and the power intensity is lower than that of the existing conventional chip. The radiation dose of blue light is smaller, so that the content of blue light in the white light obtained by mixing the emitted light of the chip and the excitation light of the phosphor powder is lower. At the same time, by combining green phosphors and red phosphors with specific excitation wavelengths, the mixed white light has better saturation. |
