Abstract

The invention relates to an illuminating device with a blue light reducing microstructure. The illuminating device comprises an aluminum substrate, an LED white light chip and a glass substrate which are horizontally arranged at intervals up and down; the blue light reducing structure comprises a blue light narrow-band reflecting film and a titanium oxide coating layer which are arranged at an interval, the blue light narrow-band reflecting film comprises a first silicon oxide film, a first titanium oxide film, a second silicon oxide film and a second titanium oxide film which are arranged in sequence, and the titanium oxide coating layer wraps the LED white light chip and is laid on the absorption surface of the aluminum substrate; blue light of the LED white light chip is reflected to the titanium oxide coating layer through the blue light narrow-band reflecting film to be absorbed, harmful high-energy photons in the wave band of 420 nm-450 nm can be greatly reduced, the blue light reducing effect is improved, and the anti-blue light effect for specific children crowds is achieved; and the processing difficulty and the process cost are reduced, and the application crowd of the illuminating device is expanded.

Description

technical field [0001] The invention relates to the field of lamp structures, in particular to a lighting device with a microstructure for reducing blue light. Background technique [0002] Due to its energy saving, long life, environmental protection and other characteristics, LED lighting devices are widely used in daily life and are gradually replacing conventional lighting sources. Based on the light-emitting principle of white LEDs, the higher the brightness of LED lighting with the same power, the more blue light components in the lighting light. Blue light can easily cause eye damage, especially macular degeneration. Blue light can penetrate the lens and reach the retina, causing optical damage to it, accelerating the oxidation of cells in the macular area, generating a large number of free radicals, leading to cataracts and macular degeneration. [0003] According to research, the degree to which blue light is harmful to the eyes varies by age. For older people, t...
