Color balance anti-blue-ray lens, glasses and equipment and manufacturing method thereof

Abstract

The invention discloses a color balance anti-blue-ray lens, glasses and equipment and a manufacturing method thereof. An all-dielectric multilayer film pile with characteristics of two selective transmission attenuation band characteristics is deposited on the front side of a lens body; a wide-band anti-reflection multilayer film pile of the visible light band is deposited on the back side; the color balance anti-blue-ray lens meet the requirements that the transmission rate at the 420nm to 450nm band is lower than or equal to 65 percent; the transmission rate at the 565nm to 595nm band is lower than or equal to 70 percent; the transmission rate at the 460nm to 555nm band is higher than or equal to 85 percent; the transmission rate at the 605nm to 700 nm band is higher than or equal to 85 percent; the transmission rate at the 300nm to 380nm band is smaller than or equal to 1 percent; the color coordinate of the integral transmission spectrum is positioned in a range (0.333+ / -0.005, 0.333+ / -0.05). The proper high-low-refractive-index film layer design is selected, so that the transmission attenuation can be realized in the specific high-energy blue-ray band; the corresponding attenuation compensation can be performed in the color complementation band, so that the anti-blue-ray human eye protection without color balance distortion can be realized. The color balance anti-blue-ray lens, glasses and equipment and the manufacturing method have the advantages that the structure is compact; the manufacturing process is simple; the cost is low; the large-scale production is easy.

Description

technical field [0001] The invention relates to a living device, in particular to a color-balanced anti-blue light lens, glasses, equipment and a manufacturing method thereof, which can be applied to fields such as display and life medicine. Background technique [0002] At present, the display screen or lighting system on the market is often realized by white LED, because the LED light source has the advantages of low-voltage power supply, low energy consumption, strong applicability, high stability, short response time, no pollution to the environment, and multi-color light emission. At present, the most common way to prepare white LEDs is to use gallium nitride blue LEDs plus YAG phosphors. The radiation spectral intensity of gallium nitride blue LED is mainly concentrated in the range of 400-500nm, and the peak radiation intensity is limited around 415-455nm. The radiation spectral intensity of this white light LED has strong radiation intensity in blue light, especiall...
