Blue light prevention desk lamp

Abstract

The invention discloses a blue light prevention desk lamp. The blue light prevention desk lamp comprises a pedestal, a connecting element, a lamp shade and an LED light source, wherein the lamp shade with an opening is mounted on the pedestal through the connecting element; the LED light source is arranged in the lamp shade; and a blue light absorbing layer is arranged on the inner surface of the lamp shade. According to the blue light prevention desk lamp disclosed by the invention, since the blue light absorbing layer, which can filter the beam emitted by the LED light source to remove blue light and reduce outgoing blue light and can absorb blue light in the beam emitted by the LED light source, is arranged on the inner surface of the lamp shade, the blue light which is emitted outwards from the whole desk lamp, is greatly reduced, so that the desk lamp is beneficial for preventing human eyes from being hurt by blue light and plays a role of protecting the eyes. And meanwhile the desk lamp has the advantages of simple structure, energy saving and low cost, is beneficial for market popularization and application, and has a wide application prospect.
