Light source illumination: Light sources have different photoelectric characteristics due to their different emission conditions. In order to select lighting sources correctly, it is necessary to have an understanding of their electrical characteristics, photoelectric characteristics, and applicable scenarios. 1. Classification of light sources: The classification of lighting sources is based on the different forms of light emitted. It can be divided into two categories: radiation light sources and gas discharge lighting light sources. The former uses current to pass through an electric wire, heating it to an incandescent state and emitting visible light; The latter utilizes the atoms of certain elements to be excited by electrons and produce radiation.
