Beschreibung
Zusammenfassung:The invention provides a lighting source color temperature monitoring device for monitoring the color temperature change of a lighting source. The lighting source color temperature monitoring device comprises a light sensing detecting element and a comparison unit; the light sensing detecting unit is positioned close to the lighting source to sense and detect light from the light source as well as outputting real-time voltage or real-time current; the comparison unit is connected with the light sensing detecting element to preset corresponding reference voltage or reference current generated by the light sensing detecting element under different color temperatures of the lighting source; the comparison unit is used for comparing the reference voltage or reference current with the real-time voltage or real-time current. The lighting source color temperature monitoring device is able to monitor the color temperature of the lighting source on real time.
