Eye-protecting desk lamp based on double light source simulation of sunlight spectrum

Abstract

This application belongs to the field of lighting technology and discloses an eye-protecting desk lamp based on a dual-light source simulating the solar spectrum. The lamp includes a housing assembly comprising a base, a column, and lamp heads. The bottom end of the column is rotatably connected to the top center of the base. Two lamp heads are provided, each symmetrically and movably connected to the top two sides of the column via adjusting connectors, allowing the lamp heads to rotate bidirectionally along both the longitudinal and transverse axes. Each lamp head has a first light source cavity and a second light source cavity at its bottom. An LED light panel is fixedly installed in the first light source cavity, and a modified halogen lamp is detachably and fixedly connected to the second light source cavity. This application, by combining LED and xenon-aluminum lamps as light sources, leverages the advantages of both to obtain a continuous high-energy spectrum from blue light to red light and all the way to near-infrared, which is closer to the natural solar spectrum, providing a more comfortable visual experience, better color rendering, and is more beneficial to the visual health of teenagers.
