Abstract
The present invention provides a lighting fixture and lighting system for automatically adjusting a color temperature. The optimal color temperature is obtained by adjusting step by step using the light intensity, the infrared movement signal, the visibility, the human body temperature and the environment temperature. Specifically, the color temperature is compensated for and adjusted by the light sources of at least two light emitting units. In this way, the adjustment range of the color temperature is extended, making it possible to obtain the optimal color temperature.
