Investigation of photodetectors’ characteristics and assessment of their applicability for control the spectral distribution of LED luminaire light flux

Abstract

The main purpose of this research is to investigate the applicability of multi-color photodetectors for controlling the spectral distribution of LED lighting. Spectral sensitivity of various sensors in the visible region was investigated. An assessment of the possibility to control and adjust the light output of the lighting equipment in relatively narrow spectral zones has been made. The obtained results provide non-standard practical guidelines for feedback and controlling the light flow characteristics for different specialized applications.
