Description
Technical field
The present invention relates to a kind of method and system of the LED of utilization natural imitation light.
Background technology
In many cities, there are a common phenomenon in many markets and office building, and be day and night, indoor brilliantly illuminated forever.Yet this modern architecture that relies on artificial light and air conditioner ventilation fully, the people that cause living in wherein suffer from a kind of modern architecture syndrome (SBS).Its symptom shows as headache, feels sick, has a throat-ache, asthma attack etc., if the variation of the long-term imperceptible natural phenomenas of people (as daylight), building syndrome will be aggravated.So natural daylight is great to people's health, psychology and meaning of life, can not be ignored.Tested one: 1971 year, Britain scientist Order Ellsworth and cloth Reed Gus pass through the investigation to the employee of the Utilities Electric Co. of a running in 24 hours, finding to work under unalterable lamp lighting for a long time to cause sense organ sensitivity to descend, thereby reduces productivity.Experiment two: nineteen ninety-five, an investigation has been done by the horse flood operating room of Sacramento, the California, USA provincial capital, in Wal-Mart chain storage supermarket, is positioned under the skylight, overcharges 40% by the cashier of natural lighting than other position.Experiment three: at 1998 and 2002, horse flood operating room has done another investigation again, respectively 20,000 from the inferior state of markon's good fortune, the state of Colorado and Massachusetts are investigated, the result shows: in the unified examination of standard, 26% the student who gives a lesson in the daylight illumination classroom is arranged approximately, better than the student performance of giving a lesson in the artificial light classroom.Can draw the people by above three experiments and be unable to do without natural daylight, by the composition basically identical that emits beam of spectrum analysis natural daylight composition and incandescent lamp, and difference just is that natural daylight changes, and artificial light source is indeclinable.According to throughout the year seasonal variations with day alternates with night in one day, the human body natural has formed distinctive biological clock of getting along amiably and peacefully with the Nature, abnormal conditions will occur if be in the illumination servant who is different from natural daylight for a long time.So someone directly introduces indoor use with sunlight by refraction and reflection.Though this method is energy-conserving and environment-protective, pure nature just can't not have natural lighting when having sunlight.The scientist who has tries every possible means by light natural daylight to be come out at lab simulation under the situation that breaks away from the sun, but no longer has been natural daylight after changing.
Summary of the invention
The object of the present invention is to provide a kind ofly can not have sunlit place can experience the natural law of light yet, the different light that the Nature four seasons and circadian variation are produced, under the situation that breaks away from sunlight in the indoor system that utilizes LED natural imitation light that embodies.
The technical solution used in the present invention is: a kind of method of utilizing LED natural imitation light, it is characterized in that: ⑴ is divided into the different changing pattern of many groups with annual weather by the four seasons and weather conditions, and gather the brightness of time point correspondence in each changing pattern and the data of colour temperature, brightness, colour temperature and indoor temperature, the data of degree humidity of changing pattern and time point correspondence are made database; ⑵ user arranges required time point and changing pattern by button, microprocessor is controlled light that each LED lamp send corresponding brightness and colour temperature according to the pattern that the user sets by control bus under present mode, and controls air-conditioning, humidity controller, the adjusting of sound box lamp accessory temperature, humidity and the Nature sound; ⑶ transducer is gathered indoor each parameter and is sent to microprocessor, and microprocessor is compared according to each parameter of gathering and the data in the database, realizes each LED lamp is finely tuned according to comparison result.
A kind of system that utilizes LED natural imitation light is characterized in that: comprise microprocessor, LED lamp, transducer, database, described transducer has light sensor, temperature sensor, humidity sensor; Be provided with lamp pearl and the multichannel light modulation power supply of 2000K, 5700K, three kinds of 7000K or more kinds of colour temperatures in the described LED lamp; The brightness of annual various changing pattern and time point correspondence and the data of colour temperature are arranged in the described database; Indoor each parameter of each transducer collection is sent to microprocessor, and the luminous ratio of each lamp demonstrates the different-colour under the different brightness in the microprocessor control LED lamp.
The present invention also is provided with humidity controller, air-conditioning and sound equipment, in order to realize the variation of humidity, temperature and sound.
The LED that the present invention adopts is solid-state illumination light source of new generation, be the new and high technology of tool development of 21 century and potentiality, its long-life (50,000 hours), energy-conservation (than incandescent lamp power consumption minimizing 80%), environmental protection, do not contain distinguishing features such as harmful mercury metal, no infrared ray and ultraviolet radiation.Controller can go out different colour temperatures by the luminous rate regulation of adjusting two kinds of extreme colour temperature led light sources.The color LED light source can utilize the red, green, blue principle of three primary colours, under microprocessor controls, make three kinds of colors have 256 grades of gray scales and mixing arbitrarily, can produce 256 * 256 * 256=16777216 kind color, it is changeful to form different photochromic combinations, realize colourful dynamic change effect and various image, and the LED color rendering index can reach more than 90%.
The present invention is according to the different amounts that can influence the melatonin of human secretory of light component, and the lamp of the different-colour that sends.Such as, need hang down the lamp of colour temperature in the time of sleep, the lantern festival of low colour temperature makes human body produce more melatonin, thus the people is easier to be sleeping.And in work, need the light of higher color temperature, and the melatonin of human secretory can reduce, thus operating efficiency raises.
The different light that the present invention can produce the Nature four seasons and circadian variation embody indoor under the situation that breaks away from sunlight, thereby people can not have sunlit place can experience the natural law of light, comfortable, healthy life yet.
