Blue-light-removing light diffusion material, photocureable coating and LED light source

Abstract

The invention provides a blue-light-removing light diffusion material, photocureable coating and LED light source. The blue-light-removing light diffusion material comprises PC, an organosilicon lightdiffusion agent, a nano rare earth oxide and an antioxidant; the blue-light-removing photocureable coating is prepared from UV-cured acrylate, nano rare earth oxide, rare earth naphthenate and elargol; the blue-light-removing LED light source comprises an LED chip, a light-emitting surface of the LED chip is covered with a blue-light-removing fluorescent coating, which comprises fluorescent powder and the blue-light-removing light diffusion material and / or blue-light-removing photocureable coating. By adding rare earth elements in a proper proportion, harmful blue light is reduced, eye pathological harm and human body rhythm harm of myopia, cataract and maculopathy caused by blue light are effectively avoided, harmless blue light is added, melatonin secretion is inhibited, the effect of refreshing people is achieved, meanwhile, spectrum distribution is uniform, uniform and soft light emitting is guaranteed, glare is avoided effectively, and the light source provided by the invention is particularly suitable for replacing a fluorescent lamp in a classroom, so that the eyesight of children is protected.

Description

technical field [0001] The invention relates to the field of anti-blue light, in particular to a blue light-removing light diffusion material, a photocurable coating and an LED light source. Background technique [0002] There is no single white light in nature itself, but white light is produced by mixing blue light, green light, and yellow light. Green light and yellow light have less energy and are less irritating to the eyes; blue light has short wavelength and high energy, and when it reaches the fovea of ​​the macula, the lutein contained in the macula will absorb an appropriate amount of blue light, and the unabsorbed blue light will emit Excess reactive oxygen species will oxidize and damage retinal pigment epithelial cells, making retinal pigment epithelial cells unable to provide nutrition and metabolism to visual cells normally, resulting in poor nutritional supply of visual cells, and eventually leading to the death of the main visual cells in the macula.

Problems solved by technology

[0004] In daily schools and families, fluorescent lamps or LED lamps are often used as light sources for children to learn, but fluorescent lamps and ordinary LED lamps have light-emitting principles such as figure 2 and image 3 , the light source emitted by it usually has a higher intensity in the wavelength range of 415-455nm, and a lower intensity in the wavelength range of 480-500nm, which not only makes the harmful blue light intensity higher, causing damage to human eyes, but also harmless blue light The intensity is low, which increases the discomfort of human eyes
