Description

technical field [0001] The invention belongs to the technical field of circuits, and in particular relates to a multi-output circuit and a lamp. Background technique [0002] In the prior art, the LED light source has the advantages of high efficiency and energy saving, long life, low voltage controllability, etc., so it is widely used in various lamps. In special environments, lighting fixtures are essential supplies. For example, fire-fighting lamps, in the process of fire-fighting tasks, the requirements for the functions of lighting lamps are relatively high. The more functions of lighting lamps, the easier it is to perform fire-fighting tasks. However, in the control circuit of the existing fire-fighting lighting fixtures, the circuit is relatively simple. If a multi-functional circuit output is realized, multiple circuit boards are required to be combined to realize the circuit. The cost of the circuit is high and the reliability is low.
