Abstract

The invention discloses a light filter made of an organic material capable of reducing light-emitting diode (LED) blue light harm, which comprises a substrate and a light absorbing material, wherein the light absorbing material is an organic light absorbing material layer which is sandwiched in the substrate, and the absorption wavelength of the light absorbing material is ranged from 440nm to 480nm. By adopting the method, the light filter made of the organic material capable of reducing the LED blue light harm has the advantages that the content of blue light spectrums in white light spectrums can be reduced and the harmful light spectrum range which affects the health of human beings and organisms is decreased.

Description

technical field [0001] The invention relates to the technical field of optical lighting, in particular to an organic material filter for reducing the blue light hazard of LEDs (light emitting diodes). Background technique [0002] The new LED (light emitting diodes, light-emitting diode) lighting source is gradually replacing the conventional lighting source due to its energy-saving, environmental protection, and durable characteristics, and has become the development trend of mainstream world lighting. With the expansion of the LED industry and its wide application, the impact of LEDs on the human body has begun to receive attention. Although LED lighting technology has obvious advantages in energy saving and high-efficiency lighting, at the same time, the harm of LED light sources to the retina and the impact on the rhythm of biological daily life also remind us to clearly see the risks of LED lighting on human biological safety. At present, most of the white LED light is...
