Environmental light self-adaptive adjusting method used for biological clock adjusting glasses

Abstract

The invention discloses an environmental light self-adaptive adjusting method used for biological clock adjusting glasses. The environmental light self-adaptive adjusting method includes the following steps: step 1, presetting an adjusting light intensity value a; step 2, monitoring and collecting an environmental light intensity value B; step 3, calculating intensity D of light which is already used in environmental light according to a formula: D=cXB, wherein c is a constant and is determined by wave length of a used light source; step 4, calculating to acquire an intensity value of light that the light source needs to provide according to a formula: E=A-D; step 5, if a value of the E is smaller than 0, closing an LED array, and if the value of the E is larger than 0, using a method of adjusting duty ratio to adjust a light intensity value of the LED array to be E according to the value of the E. The environmental light self-adaptive adjusting method is practical and more intelligent in adjusting LED lamp intensity, a light source emitted by an LED is combined with natural light to enable an intensity value of light received by a user to be constant all the time, intensity of light needed by the user can be adjusted accurately and quickly, and the user can feel more comfortable during use, so that the biological clock of a human body can be adjusted better.

Description

technical field [0001] The invention relates to a medical care control method, in particular to an ambient light self-adaptive adjustment method for biological clock adjustment glasses. Background technique [0002] Sleep is crucial to a person's normal life, but there are many people whose biological clock is disordered due to the pressure of life or the influence of the external environment, which seriously affects their physical and mental health. For example, primary and secondary school students who are under pressure to enter school, patients with sleep disorders, patients with seasonal emotional depression, business travelers who need to adjust for jet lag, long-distance drivers and shift workers, etc. The above-mentioned domestic audience exceeds 500 million. Also have a lot of products that are used to regulate external environment on the market at present, but effect is all unsatisfactory. For example, the goLITE BLU energy lamp of Philips in the Netherlands is m...

Problems solved by technology

However, due to the use of white light as the light source, it will affect the retinal visual imaging cells, and the area of ​​the curved reflector is too large, which will have a greater impact on the wearer's reading, walking and other activities

At present, the adjustment instruments on the market do not have the function of adaptive adjustment according to the ambient light
