Blue light proof LED lamp structure

Abstract

The invention discloses a blue light proof LED lamp structure comprising an LED base, an LED light-emitting chip, an LED lens and a blue light proof layer. The LED light-emitting chip is installed onthe LED base, and the LED lens is arranged on the LED base, and wraps the LED light-emitting chip; the blue light proof layer is formed by alternately arranging a plurality of high refractive index layers and low refractive index layers, and the low refractive index layers comprise SiO2; the high refractive index layers comprise one of TiO2, HfO2, Ta2O5 and OS-50, and the LED light-emitting chip comprises fluorescent powder; and the blue light proof layer is plated on the inner side, the outer side or the both sides of the LED lens. According to the blue light proof LED lamp structure, harmfulblue light wavebands are blocked effectively, and eyes are prevented from being injured by harmful blue light.

Description

technical field [0001] The invention relates to an anti-blue light LED lamp structure. Background technique [0002] In recent years, LED, as one of the new high-efficiency solid-state light sources, has significant advantages such as long life, energy saving, and environmental protection. It is widely used in a series of lighting fields such as computers, mobile phones, TVs, and LED lights and display screens. Blue light excites phosphors to form a composite light, but high-energy short-wave blue light can cause severe damage to the retina, easily causing shrinkage or even death of retinal pigment epithelial cells, and the death of light-sensitive cells will lead to vision loss or even complete loss. It is irreversible. Blue light can also cause macular degeneration. The crystals in the human eye will absorb part of the blue light and gradually become cloudy to form cataracts. Especially children’s crystals are relatively clear, which is more likely to cause macular degener...

It is irreversible. Blue light can also cause macular degeneration. The crystals in the human eye will absorb part of the blue light and gradually become cloudy to form cataracts. Especially children’s crystals are relatively clear, which is more likely to cause macular degeneration and cataracts. An LED lens is added to the LED chip to adjust the light path of the light emitted by the LED chip
