Research On The Design And Key Technology Of Eye Protection Intelligent Lighting System

At present,the indoor lighting is dominated by high brightness monochromatic lamp.The brightness and color temperature in indoor lighting can not be adjusted,such as the office and the classroom.Prolonged exposure to poor lighting can cause visual fatigue,affect the person's mood and work efficiency.The design of comfortable indoor lighting system has good practical value,which could not only protect eyesight,but also improve work efficiency.In this paper,the lighting system with adjustable brightness and adjustable color temperature is studied.And the intelligent lighting system with eye protection is designed,which could create a comfortable lighting environment.Compared with the traditional lighting system,this system has following innovative points:Firstly,the algorithm based on polar coordinates for dimming is proposed,which can relieve non polar adjustment of brightness and color temperature.In this paper,the colorimetric and luminosity parameter model under polar coordinate system is established by combining the principle of Grasman's color mixing.The chromaticity and photometric are converted into two PWM control variables to realize the independent adjustment of brightness and color temperature.This algorithm could reach the required brightness and color temperature quickly.Aiming at the jitter and flicker problems in the process of dimming,a dynamic smooth dimming mechanism is given,which enhances the sense of dimming experience.Compared with original algorithms,the accuracy of dimming have been greatly improved,and the complexity of algorithm is low.Secondly,the multi light linkage modulation mechanism based on wireless networking technology is designed.The use of self-developed wireless networking technology,lighting equipment can automatically form a network and match the lamp.Multi light linkage can be realized through the overall control and separate control of the lamps,the brightness is adjusted to receive uniform indoor lighting.Thirdly,the client dimming software is designed.The problem of speed mismatch and high latency in the dimming process is solved,and the response speed is improved.At the same time,the data flow resolution mechanism is proposed to optimize the fault-tolerant performance.The humanized interface design makes the operation become simple and convenient.Finally,the intelligent eye lighting system is fully tested.The test data show that the system has achieved the expected design requirements.At the same time,some research results in this paper have been applied and the market reflectes well.
