Abstract

The invention discloses an LED (Light-Emitting Diode) doped optical filter, which comprises a first substrate, a second substrate, a first light absorbing material and a second light absorbing material, wherein the first light absorbing material is doped in the first substrate; the second light absorbing material is doped in the second substrate; both the first light absorbing material and the second light absorbing material comprise rare-earth oxides; the absorbing wavelength of the first light absorbing material is 570-600 nanometers; and the absorbing wavelength of the second light absorbing material is 440-480 nanometers. Due to the adoption of the LED doped optical filter, the spectral content of two segments of different wavelengths in a white light spectrum can be readjusted, the color rendering of an LED is enhanced, and unbeneficial spectrum bands which influence the health of human beings and organisms are reduced.

Description

technical field [0001] The invention relates to the technical field of optical lighting, in particular to a doped filter for improving the color rendering of LEDs (light emitting diodes) and reducing blue light hazards. Background technique [0002] The new LED (light emitting diodes, light emitting diode) lighting source is gradually replacing the conventional lighting source and becoming the mainstream lighting field in the world due to its energy-saving, environmental protection and durable characteristics. Although LED lighting technology has obvious advantages in terms of energy saving and high-efficiency lighting, at the same time, the poor color rendering of LED light sources can easily lead to color weakness, which cannot restore true colors, and there are different proportions of ultraviolet and blue spectrum segments in the spectrum of LEDs. These are affecting the rhythm of our daily life, and at the same time reminding us to clearly see the risks of LED lighting ...
