A stage light free from damage of sunlight includes a light body and a control assembly, and a light avoiding system. When the light body is in a power-on state, the control assembly controls the light avoiding system not to work; and when the light body is in a power-off state, the control assembly controls the light avoiding system to implement a light avoiding action. According to the present invention, smart light avoiding according to a sunlight status can be achieved by means of a light avoiding system. The light avoiding system has advantages of a high automatic recognition level, a flexible access system, and being cost-effective and easy to implement.
