1. A lamp power supply based on dual-bus control, comprising:
an input module configured for providing alternating current, a rectifying module configured for converting input alternating current into direct current, and a driving module configured for controlling load driving, wherein:
the input module, the rectifying module and the driving module are connected to each other through a dual bus, and the lamp power supply further comprises:
a detection module, configured to acquire and detect a bus voltage output by the rectifying module;
a data transmission module, configured to transmit configuration control information; and
a control module, configured to send a turn-on signal to the data transmission module to receive the configuration control information provided by the data transmission module, in the case that the detection module detects that the bus voltage is less than a first preset voltage, and
wherein the detection module and the data transmission module are connected to the dual bus through respective wires, so that the detection module and the data transmission module are both connected to the rectifying module.
