LED material for filtering yellow lights

Abstract

The invention relates to the technical field of polymer materials and particularly relates to a LED material for filtering yellow lights. The LED material for filtering yellow lights is prepared from 60 to 100 parts by mass of a substrate, 1 to 13 parts by mass of lauric acid diethanolamide, 0.1 to 1.0 part by mass of boron nitride, 0.1 to 0.8 parts by mass of tetrafluoroethylene, 0.2 to 0.4 parts by mass of a dispersant DP310 and 2 to 26 parts by mass of ethylene bis-stearamide, wherein the lauric acid diethanolamide is one or more of epoxy propane, neodymium oxide, polyvinyl alcohol and glass fibers. The LED material for filtering yellow lights has excellent optical performances of yellow light filtering, light transmittance and haze, can effectively filter and eliminate yellow lights produced by a LED lamp, can relieve eye fatigue and can prevent eye damage caused by yellow lights.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an LED material for filtering yellow light and a preparation method thereof. Background technique [0002] The energy crisis, the greenhouse effect, and the reality of the deteriorating ecological environment have prompted people to look for energy-saving lighting alternatives. Light-emitting diode (Light Emitting Diode, LED), because of its small size, long life, rich color and outstanding energy-saving and environmental protection features, has been increasingly widely used in the fields of display, transportation, electrical appliances and lighting. One of the key technologies for cleaner production and sustainable development. my country's LED industry has begun to take shape and has a good momentum of development. However, because the general LED light source is white light, and it is easy to produce yellow light, it will cause eye fatigue, so it needs to be el...

AI Technical Summary

Problems solved by technology

However, because the general LED light source is white light, and it is easy to produce yellow light, it will cause eye fatigue, so it needs to be eliminated.

At present, there is no report about filtering yellow light in LED lamps in relevant literature and patents. Traditional glass production technology uses neodymium oxide rare earth to achieve similar effects. However, due to the variety of LED lamp materials, there are PC, PMMA, PCTG And other materials, the refractive index of the material is different, resulting in a large gap in the light transmittance and haze of the modified material, so it is particularly important to find a matching light-absorbing filler
