Natural visual environment desk lamp imitating super visual area, and control method

Abstract

The invention discloses a natural visual environment desk lamp imitating a super visual area, and a control method. The natural visual environment desk lamp comprises a light regulating device, an array lamp panel and a photodetector, wherein the array lamp panel comprises a multispectral array lamp bank composed of seven kinds of visible light and A ultraviolet light sources and used for generating and controlling simulated natural spectra; the illumination of a detected area is transmitted to the light regulating device through the photodetector, and the light regulating device comprises anillumination control module and an spectral rhythm control module with preset optical environment data of the super visual area; the illumination control module is used for starting and controlling the multispectral array lamp bank so that control over the illumination is achieved, and the spectral rhythm control module is used for controlling the multispectral array lamp bank so that the controlover spectral rhythm is achieved. The invention provides the desk lamp with natural light distant vision and tracing vision training devices, and according to the desk lamp, the natural light illumination, spectra and rhythmic change of the simulated super visual area are controlled with an intelligent technology; and a health mini-vision environment working area for preventing myopia at a critical period of an eyeball development window is formed.

Description

technical field [0001] The invention relates to the technical field of visual environment adjustment, in particular to a table lamp imitating the natural visual environment of a super visual zone and a control method. Background technique [0002] Epidemiological surveys show that the incidence of myopia in the world is still increasing year by year. According to data, there are currently 1.4 billion people suffering from myopia in the world, and it is expected to increase to 2.5 billion by 2020. The proportion of myopia in mainland China is 47%. Together with the United States, Japan, Singapore and China's Hong Kong and Taiwan regions, it belongs to the region with the highest rate of myopia in the world. Recent epidemiological surveys in the United States, Singapore, Australia, China and other regions have found that children with myopia spend less time outdoors than children with emmetropia. It is also found that 2 to 3 hours of outdoor activities and exposure to natural ...

Problems solved by technology

[0014] There are full-spectrum halogen lamps (such as SOLUX halogen lamps, color temperature: 4700k), with a wide spectral range of 380nm-760nm, and a peak wavelength around 600nm, including short-wavelength ultraviolet light, purple light, and medium-wavelength light with high energy Yellow light, green light, and long-wavelength red light, but the spectral peak is obviously biased towards the red light range; the spectrum and illuminance of the mixed light "solar spectrum LED eye protection panel light" will not change, and it cannot be adjusted during the day The spectrum changes with natural light
