Investigation, Analysis and Improvement of Induction Lamp Based on SPSS and MATLAB

Firstly finding out the main existing problems of common induction lamps by interviews and questionnaires, this paper, with SPSS analyzing the collected questionnaire data after summarizing and find out its future improvement direction, proposes an induction lamp with following 2 ideas to be verified. The first is its brightness self-adapted to the ambient light. The second is the time of controlling the on and off by judging if someone passes by, more importantly, its brightness self-adapted to the distance between the body and the lamp. With Matlab used to build a function model based on the ambient brightness data from the light sensor, the least square and the best fitting curve are used to determine the functional relationship between CRR (the value is related to the duty ratio of PWM wave controlling the brightness) and ambient brightness, on the basis of it, with Simulink simulating its advantage in energy saving strategy and Proteus hardware simulation illustrating its functional feasibility, verified by real object's data as well.
