Description

Technical Field

[0001] The utility model belongs to the field of simulating solar light sources, and in particular relates to a solar spectrum-like light source. Background Art

[0002] In the prior art, solar spectrum-like light sources are generally evaluated by spectral fitting coefficient (GFC) and spectral relative difference index (ASD), but they do not fully cover the visible spectrum range, so there are certain limitations in evaluating the healthy lighting effect. Therefore, most of the full-spectrum solutions in the prior art lack the 380-420nm violet light part, while 400±20nm violet light can prevent myopia-short-wavelength light slows the growth of refractive eyes, can produce hyperopic reactions, and inhibit lens-induced myopia. Cone cell signaling plays a role in the hyperopic reaction of violet light. The use of near-infrared light (670nm) to correct aging mitochondrial function can improve its membrane potential and adenosine triphosphate production, and reduce age-related inflammation, which is beneficial to the treatment of retinal aging and retinal-related diseases (such as macular degeneration). Therefore, there is a certain deviation between the solar spectrum-like light source in the prior art and the actual solar spectrum. Utility Model Content
