Public place light control method

Abstract

The invention discloses a public place light control method. The method aims at seriously controlling the light at night, and provides four natural standards for controlling: firstly, the brightness of the light needs to adjust to illuminance on the ground when the moon is full, the illuminance is about 0.2lux; secondly, the spectrum needs to adjust to the spectrum of candle light in a visible light range; thirdly, the luminophor is free from stroboflash, namely, the change speed of the light needs slow and uses the endogenous rhythm of human as the reference (one period is about 24 hours); fourthly, the light space needs uniform, and cannot have glare. The invention further provides a method for full-blacking the classroom when the students attend the Chinese, English and like language classes according to the control method, thereby reducing the eye using time of the student to a great extent and increasing the secretion of the melatonin of the student; the invention further considers a method for controlling light of barracks, thereby increasing the male hormone level of the personnel in the barrack. Through the adoption of the method disclosed by the invention, the light is seriously controlled from four aspects: spectrum, illuminance, frequency and glare so as to guarantee the health and security of the people.

Description

technical field [0001] The invention relates to public health and lighting, in particular to a method for controlling light in public places. Background technique [0002] Public places refer to classrooms, dormitories, barracks, hospitals, stadiums, subways, squares, shopping malls, streets and other places where many people gather. Now these places are brightly lit, and advertisements displayed or broadcast on light boxes, large LED screens, and TV screens are overwhelming, turning night into day. semiconductor lighting (see figure 1 Neutral white LED spectrum 1) and display have the advantages of energy saving and low cost of use, and people use it unrestrainedly, resulting in light pollution. [0003] A major component of light pollution is its blue light hazard (see figure 1 Blue light peak 1A of neutral white LED), because blue light is a three-primary color, without blue light, there will be no white light and color images. Besides, natural light during the day (se...

Problems solved by technology

[0007] There are four misunderstandings in modern lighting and display (1) At night, the white light of the day is wrongly pursued in terms of spectrum, that is, figure 1 Natural light spectrum in 4; (2) In terms of brightness, the brighter the better, although some lamps can also be dimmed, but the low value of the adjustment range and the purpose of adjustment deviate from the purpose of health (3) In terms of strobe, advertisements pass Flickering to attract eyeballs; displaying images synthesized through the persistence of vision of the human eye, that is, light is changing rapidly, and its frequency far interferes with the internal rhythm of human beings; extensive use of pulse width modulation technology to synthesize colors (spectrum) and adjust Brightness, compared to the amplitude modulation technology advocated by the present invention, is obviously more harmful, and also includes the rapid change of light that is different from the internal rhythm of human beings

(4) In terms of glare, a large number of items with smooth surfaces such as electroplated parts and glass are used. Although they are high-end, the reflected light produced by local angles is particularly bright (that is, glare), which sometimes seriously damages retinal cells, and this glare is compulsive. Yes, for example, when we pour boiling water, our eyes have to receive the glare from the outside of the shiny glass until the pour is over.

Fourth, when designing products and projects, the hazards of partially reflected glare must be fully considered. Obviously, the current lighting and displays have seriously deviated from these four goals, especially the current lighting and displays in public places are even more unscrupulous, so it may It has seriously affected people's health; if these goals can be regained, it may be possible to curb the vicious development of myopia and fertility in the country
