Abstract
The present disclosure relates to an emergency lighting circuit, an emergency start control method thereof and an emergency lighting system. When an emergency start condition is met, matching can be performed in a preset dimming database according to type information of load lighting equipment connected to a current emergency lighting circuit to obtain a dimming parameter value matching a power value required by the load lighting equipment, and finally, the load lighting equipment is directly controlled to start with the dimming parameter value. Through the above solution, when emergency lighting is started, there is no need to spend time in regulating power of the load lighting equipment, and a corresponding power value can be ensured when the load lighting equipment is started, which is highly reliable in emergency lighting start.
