In order to facilitate understanding of the embodiment, first, a healthy lighting method and an intelligent lighting control system for simulating natural light change disclosed in the embodiment of the invention are described in detail.
The first embodiment is as follows:
the embodiment of the invention provides a healthy lighting method for simulating natural light variation trend, which can also be a healthy lighting method for simulating natural light variation in different light climate areas, as shown in fig. 1, and the method comprises the following steps:
s11: and collecting natural light data, obtaining natural illumination data, combining the color temperature data with a preset formula to calculate natural illumination values of a plurality of regions, and obtaining an indoor illumination curve simulating the natural light variation trend.
Preferably, the calculation method of the simulated day-to-day natural light illumination quantity can be as follows: first, each region is obtainedSunshine hours and a total radiation value Q obtained by a ground meteorological station; then, the local illuminance value of each month is calculated according to a formula, wherein the formula is KQA + b1N + b2H + b3e + b4s, where N is the station geographical latitude in degrees and H is the station altitude in meters; e is the average absolute humidity of each month of the measuring station, the unit is millibar, and s is the sunshine of each month of the measuring station; then, according to formula EQ＝Q×KQAnd (5) calculating illumination values of all seasons of the year. As a preferred embodiment of the present embodiment, the amount of light received can be classified into indoor and outdoor light receiving amounts according to the activity patterns of a person. The indoor light quantity can be calculated by combining the lighting coefficient of the building with the total natural light quantity. The outdoor is divided into two cases: when directly exposed to natural light, the total illumination of the natural light is used for calculation; when in the shade of a shade, the scatter luminance values are used. And calculating the daily average light receiving quantity of people in each season of the region, and calculating the maximum daily light receiving quantity of people in each season of the region.
Therefore, the healthy lighting method for simulating the natural light variation trend of different light climate areas can obtain the annual average total illumination value, each seasonal illumination value, each month illumination value and the like of the different light climate areas through calculation, and an indoor illumination variation curve is obtained by combining the values and the light receiving quantity.
According to the natural light illumination value, a visual efficacy curve is referred, and 300-3000lx is taken to be combined with the outdoor natural light change value of the region to obtain y-ax simulating the natural light change trend2The indoor illuminance variation curve of + bx + c (x is outdoor illuminance, a, b, c are constants, y is indoor illuminance, and the variation curve may be a polynomial of a higher order).

The third type of photoreceptor cells (ipRGCs) are referred to as non-visual cells. The iRGCs control the human circadian rhythm, body temperature, heart rate, cortisol, melatonin secretion and alertness and other non-visual biological effects, the human circadian rhythm is influenced by light, the light controls the pineal body to secrete the melatonin, so that the sleep and emotion of the human are influenced, and the light intensity and spectral power distribution influence the melatonin secretion to a great extent. People are easy to have related physiological and psychological health problems in the area with lack of sunlight. Lack of natural light irradiation will have great influence on the biological rhythm of human body, such as biological clock, hormone level in body, emotion, etc.
Therefore, the light is closely related to the biological rhythm of the human body, the natural light is most consistent with the biological rhythm of the human body, and the illumination quantity of different light climate areas has larger difference. For example, in sunlight-deficient areas, many cities or regions lack natural light, and people have related physiological and psychological health problems in sunlight-deficient areas. Artificial light intensity, light source spectrum, etc. can affect the biorhythm of human.
With respect to the prior art, conventional lighting merely meets the basic visual function criteria specified, and does not adequately account for the effects of lighting on human biorhythms. In addition, in the areas with lack of sunlight, the people can work in the artificial light environment which only meets the illumination requirements of the basic visual function for a long time, the physiological rhythm and the health of the people are easily influenced, and researches indicate that illumination switched between strong and weak illumination has obvious influence on a non-visual system. The lack of natural light irradiation in human body caused by long-time activities indoors or lack of sunshine in the area can generate great influence on the biological rhythm of human body, such as biological clock, hormone level in human body, emotion and the like.
The method comprises the steps of collecting natural light data, obtaining natural light illumination data, calculating natural light illumination values of a plurality of regions by combining color temperature data and a preset formula, and accordingly obtaining an indoor illumination control parameter curve simulating the natural light variation trend, enabling the LED lamp to illuminate according to the illumination control parameters, simulating illumination of the natural light variation trend in the regions, achieving illumination simulating the natural light variation trend from the aspect of illumination by utilizing artificial illumination, and enabling a user to receive simulated artificial light. Therefore, the illumination intensity and time adaptive to the natural light are obtained through derivation and calculation, and the scientific healthy illumination method is achieved.

s21: the method comprises the steps of collecting natural light data, obtaining natural illumination data, combining the color temperature data with a preset formula to calculate natural illumination values of a plurality of regions, and combining a visual effect curve to obtain an indoor illumination curve simulating natural light variation trend.
In this step, the preset formula includes: kQ＝a+b1N+b2H+b3e+b4s, wherein, a, b1、b2、b3N is the geographical latitude of the preset land, H is the altitude of the preset land, e is the average absolute humidity of the preset land within the preset time, s is the sunshine of the preset land within the preset time, K is the regression coefficientQIs a preset radiant equivalent. The preset formula further comprises: eQ＝Q×KQWherein Q is the total radiation value, EQFor presetting the total illuminance value, K, of the terrestrial light climateQIs a preset radiant equivalent. And calculating the maximum daily average received light quantity Emax of daily activities of people in the region according to the activity mode of the people. According to the natural illuminance value, referring to the visual efficacy curve, combining the outdoor natural light change value of the area with 300-3000lx, taking winter as an example, and if the sampling interval is 15 minutes, finding out the natural illuminance critical value E at the sampling time according to the collected natural light data0Natural light color temperature data KnAs shown in Table 1, the illuminance collected at this time is denoted as EOuter coverAnd calculating according to the table formula to obtain an indoor illumination change trend curve simulating the change of natural light. As shown in table 2 below:
the preset time can be a time period of one quarter, one month, one week and the like. As a preferred scheme, the preset time is one month, so that e is the average absolute humidity of places in each month, s is the sunshine of places in each month, KQIs the equivalent of radiant light somewhere in each month, EQ＝Q×KQQ in (1) is the total radiation value in each month.
It should be noted that the regression coefficient (regression coefficient) represents a parameter indicating how much the independent variable x affects the dependent variable y in the regression equation. A larger regression coefficient indicates a larger effect of x on y, a positive regression coefficient indicates that y increases with increasing x, and a negative regression coefficient indicates that y decreases with increasing x. For example, in the regression equation Y ═ bX + a, the slope b is called a regression coefficient, and represents that X varies by one unit, and on average, Y varies by b units.
