[0041] This application also relates to a method for preparing the LED lamp, which at least includes the following steps:
[0042] (1) Add the rare earth oxide to the organic solvent I according to the proportion, and then add the coupling agent to obtain the blue light absorber after dispersion; the mass percentage concentration of the rare earth oxide in the blue light absorber is 30%-50%, Organic solvent I is selected from a mixed solvent of xylene and cyclohexanone;
[0043] (2) Anatase titanium dioxide powder, rare earth element oxide powder and triethyl borate are mixed in proportions and then ground, and ground at 60-100°C for 6-15 hours to obtain particles with a particle size of 10nm or less Nano powder; disperse the prepared nano powder in an organic solvent II to form a sol. The organic solvent II is selected from a mixed solvent of ethyl acrylate and cyclohexanone. The mass percentage of the nano powder in the sol is 30-40 %; That is, a coating containing titanium diox...
Embodiment 1
[0058] An LED lamp includes an LED luminous body and a lamp tube covered outside the LED chip. The lamp cover contains a blue light absorber, and the blue light absorber contains rare earth oxides with a particle size ranging from 5 to 60 nm; the surface of the lamp cover is provided with The environmental purification functional layer contains a titanium dioxide photocatalyst doped with rare earth elements and boron elements.
[0059] among them:
[0060] (1) The preparation method of blue light absorber is:
[0061] Add coupling agent to the mixed solvent of xylene and cyclohexanone (volume ratio 4:1), then add rare earth oxides, and relax. The mixing method adopts shaking with an ultrasonic generator at 40°C for 40 minutes to mix the system Until a red-yellow transparent homogeneous liquid composition is formed, a blue light absorber is obtained; wherein the mass percentage concentration of the rare earth oxide in the blue light absorber is 50%, and the addition amount of the cou...
