Abstract

The invention discloses a coated filter of reducing harmfulness of LED blue light, which comprises a base body and a light absorbing material; and the light absorbing material is a coating film located on the surface of the base body and is a rare earth oxide along with an absorbing wavelength of 440-480nm. In this way, the coated filter of reducing harmfulness of LED blue light can reduce blue light spectrum content in white light spectrum for reducing harmful spectrum range influencing health of the people and organisms.

Description

technical field [0001] The invention relates to the technical field of optical lighting, in particular to a coated filter for reducing the hazard of blue light from 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 produ...
