Design of intensity detection system for flashing lights based on Labview

To evaluate performance of flashing lights,a new intensity detection system for flashing lights is developed based on the Labview platform in this paper,which not only can detect the flashing waveform in a certain period of time,but also can exactly calculate the peak intensity,efficient intensity,flashing frequency and the flashing time at a high-speed.The parameter calculation principles,hardware configurations and Labview program design are introduced and a effective method is proposed to resolve the problem of data loss easily in the data acquisition process.Finally,detected data are stored by controlling Excel formats.Experimental results show that the designed system can easily detect any flashing waveforms with flashing time greater than 0.1 s,and the acquisition maximum time reach 10 s.It can do a better evaluation for the performance of flashing lights.
