Problems solved by technology

Although this method is energy-saving and environmentally friendly, it is purely natural, but it cannot have natural light when there is no sunlight
Some scientists have tried to simulate natural light indoors without the sun through lighting, but it is no longer natural light after conversion.

Embodiment Construction

[0011] Below in conjunction with accompanying drawing and specific examples the present invention will be further described:

[0012] From figure 1 As can be seen, the present invention comprises the following parts:

[0013] 1. Microcontroller: Control each lamp to emit light with corresponding intensity and color temperature according to the mode set by the user in the current mode through the control bus, and control the air conditioner, humidity controller, audio lamp accessories to adjust the temperature, humidity, and nature sound;

[0014] 2. Various sensors: equipped with light sensor, temperature sensor and humidity sensor to detect the brightness, temperature and humidity of indoor light;

[0015] 3. LED lights: Each LED light is equipped with three or more color temperature lamp beads of 2000K, 5700K, 7000K and multi-channel dimming power supply. The dimming power supply can receive the system bus control signal to control the lighting ratio of the three lights I...

Abstract

The invention discloses a method and a system for simulating natural light by an LED (light emitting diode). The system is characterized by comprising a microprocessor, an LED lamp, a sensor and a database, wherein the sensor is provided with a light sensor, a temperature sensor and a moisture sensor; lamp beads of three or more color temperatures of 2000K, 5700K and 7000K and a multipath light regulation light source are arranged in the LED lamp; the database comprises the data of various yearly variation modes of luminance and temperature color corresponding to time points; each indoor parameter collected by each sensor is sent to the microprocessor; and the luminescence proportions of three lamps in the LED lamp are controlled by the microprocessor to display different color temperatures under different types of luminance. According to the invention, different lights generated by the variation of natural four seasons as well as day and night can be embodied indoors under the condition of no sunlight, so that people can feel the nature law of light in places with no sun irradiation, and therefore people can comfortably and healthily live.

Description

technical field [0001] The invention relates to a method and system for using LEDs to imitate natural light. Background technique [0002] In many cities, there is a common phenomenon in many shopping malls and office buildings. The interior is always brightly lit, day and night. However, this kind of modern building, which completely relies on artificial light and air-conditioning ventilation, causes people living in it to suffer from a kind of modern building syndrome (SBS). Its symptoms are headache, nausea, sore throat, asthma attack, etc. If people do not feel changes in natural phenomena (such as sunlight) for a long time, building syndrome will be exacerbated. Therefore, natural light is of great significance to people's body, psychology and life, and cannot be ignored. Experiment 1: In 1971, British scientists Aldsworth and Bridgs investigated the employees of a 24-hour electric power company and found that working under constant electric light for a long time woul...
