The invention provides an LED driving power supply. The LED driving power supply comprises an input rectification module, a power supply module, a power supply module, a current regulation signal generation module and a current regulation setting module, wherein the current regulation setting module provides current regulation setting information for the current regulation signal generation module, and the current regulation setting information is preset and fixed for any different lamp; the current regulation signal generation module outputs a current regulation signal to the power supply module according to the current regulation setting information provided by the current regulation setting module; and the power supply module outputs a load power supply required by the LED load according to the current regulation signal output by the current regulation signal generation module. According to the LED driving power supply, the output current can be flexibly adjusted, one set of hardware scheme can meet the requirements of different projects, and the overall design and the production cost is reduced.
Description
technical field [0001] The present application relates to the technical field of circuit design, in particular to an LED drive power supply that can flexibly adjust output current. Background technique [0002] Due to the different voltage, current, and luminous flux specifications of LED lamps, the LED specifications in different projects are different, and the series and parallel connections are different, which makes the voltage and current required for the LED drive power supply often inconsistent. The output voltage of the constant current LED drive power supply has a certain range of adaptation, but the output current is fixed, which cannot flexibly meet the needs of different lamps. This leads to more types of driving power sources and more types of materials. It is impossible to reduce material costs through mass procurement, and it also leads to production complexity and cannot reduce production costs through large-scale production. This requires a universal design...
