Problems solved by technology

[0002] The current LED white light lighting is basically packaged on the blue LED with glue mixed with yellow phosphor powder to convert part of the blue light into yellow light, and the blue light and yellow light are mixed to obtain white light, but the white light realized by this method contains Blue light generally has relatively more components, long-term use will cause damage to eyesight and health, and the color rendering index of this white light is low, which cannot truly reflect the original color of the object

Embodiment 1

[0060] When preparing LED lamps, blue LEDs are used. When the blue LEDs are packaged, no fluorescent powder or quantum dots are added to the glue, and 0.4wt% quantum dots are mixed into the diffusion plate. The composition of the quantum dots includes red quantum dots, orange quantum dots, Yellow quantum dots and green quantum dots Quantum dots. Among them, the lighting spectrum of LED lamps is as follows: figure 1 shown.

Embodiment 2

[0062] The difference from Example 1 is that 0.6wt% phosphor powder is mixed into the diffusion plate, wherein the composition of the phosphor powder includes red phosphor powder, orange phosphor powder, yellow phosphor powder and green phosphor powder, and the proportion of phosphor powder of each color is the same as Example 1. Among them, the lighting spectrum band distribution of LED lamps and figure 1 similar.

Embodiment 3

[0064] The difference from Embodiment 1 is that 0.2wt% quantum dots are mixed into the diffusion plate, wherein the composition of the quantum dots includes red quantum dots and cyan quantum dots. The blue LED is packaged with ordinary yellow fluorescent powder glue, and finally the lighting spectral distribution of the LED lamp is obtained. figure 1 similar.

Abstract

The invention discloses a method for regulating and controlling the illumination spectrum of an LED lamp and the LED lamp. The method for regulating and controlling the illumination spectrum of the LED lamp comprises the following steps that quantum dots and / or fluorescent powder are / is dispersed in a diffusion plate of the LED lamp, the quantum dots and / or the fluorescent powder are / is suitable for generating a spectrum of an expected wave band under excitation of LED light sources, and illumination light of a needed color is achieved. According to the method, the quantum dots and / or the fluorescent powder are dispersed in the diffusion plate to obtain the illumination light with the needed color, so that heat dissipation of LED lamp beads cannot be affected, the stability and the service life of the quantum dots and / or the fluorescent powder can be improved, and meanwhile the waveband distribution of the illumination spectrum of the LED lamp can be improved.

Description

technical field [0001] The invention belongs to the display field, and in particular relates to a method for regulating and controlling the lighting spectrum of an LED lamp and an LED lamp. Background technique [0002] The current LED white light lighting is basically packaged on the blue LED with glue mixed with yellow phosphor powder to convert part of the blue light into yellow light, and the blue light and yellow light are mixed to obtain white light, but the white light realized by this method contains Generally, there are relatively many blue light components, and long-term use will cause damage to eyesight and health. Moreover, the white light has a low color rendering index and cannot truly reflect the original color of the object. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a method for regulating t...
