Description
Technical Field
The invention relates to the technical field of illumination, in particular to a blue light removing coating.
Background
Nature does not have separate white light, but the blue light is mixed with the green light and the yellow light to form white light. Green light and yellow light have less energy and are less irritating to eyes; the blue light wave is short, the energy is high, when the blue light reaches the fovea centralis of the macula lutea, lutein contained in the macula lutea can absorb a proper amount of blue light, the incidence of unabsorbed blue light can generate active oxygen, the excessive active oxygen can oxidize and damage retinal pigment epithelial cells, so that the retinal pigment epithelial cells cannot normally provide nutrition and metabolism for visual cells, the visual cell nutrition supply is poor, the main visual cells in the macula lutea are dead, the visual cells are non-renewable, and the visual health is greatly influenced. Especially for children, the retina macula has weak blue light absorption capacity, so that the blue light radiation received by the retina is about 2 times that of adults, and therefore the blue light radiation has the greatest influence on the eyesight health of children and is the group which needs protection most.
In the blue light, not all the wavelengths of the blue light can cause damage to human eyes, as shown in fig. 1, the damage of the 415-455nm wavelength blue light to retinal pigment epithelial cells is 2-4 times of the 480-500nm wavelength blue light, which belongs to harmful blue light and is a wavelength range that needs to be removed particularly; the 480-one 500nm wavelength range blue light has low damage to retinal pigment epithelial cells and large effect of suppressing melatonin secretion, but plays a role in making people refreshed, belongs to harmless blue light and is a wavelength range which needs to be reserved.
In daily schools and families, a fluorescent lamp or an LED lamp is mostly used as a light source for children to study, but due to the light emitting principle of the fluorescent lamp or the common LED lamp, as shown in FIG. 2 and FIG. 3, the light source emitted by the fluorescent lamp or the common LED lamp usually has higher intensity in the range of 415-.
The traditional blue light source that goes realizes going the blue light effect through adopting special light source chip packaging material and packaging technology, like the eyeshield LED lamp for classroom that CN201810417533.8 disclosed, including lamp shade, LED luminescence chip, blue light subduct the device, the beam split effect through the prism throws the position of difference with the light of different wavelengths, then subdues blue light and the complementary yellow light of blue light simultaneously, has so both avoided the blue light to harm eyesight and can keep the color balance of light source to guarantee the color rendering of light source again. In the mode, the LED chip needs to be redesigned and manufactured, so that the cost of the lamp is greatly increased, and the popularization is not facilitated.
