| titleOfInvention | LED lamp bead fluorescent powder capable of reducing blue light harm, LED lamp bead and preparation method of LED lamp bead fluorescent powder |
| abstract | The invention relates to the technical field of LED lamp bead manufacturing, and particularly discloses LED lamp bead fluorescent powder for reducing blue light harm, an LED lamp bead and a preparation method thereof. The LED high-wavelength blue light chip adopted by the fluorescent powder for reducing the blue light hazard, the LED lamp bead and the preparation method thereof are formed by superposing P-GaN, MQWs, N-GaN and Sapphire, the main wavelength is 465 and 470nm, the peak band of the short-wave blue light emitted by the LED lamp bead at present is shifted to 464nm from 430 and 455nm (the typical value is 450 nm), the harmful blue light is eliminated from the aspect of a light source, the color cast cannot be caused, the high luminous efficiency and the color rendering index of an LED lighting product are ensured, and a Liquid Crystal Display (LCD) can normally display images. |
