LED (light-emitting diode) power source analysis and test system

Abstract

The invention discloses an LED (light-emitting diode) power source analysis and test system, which comprises a variable electronic load, an alternating current-direct current electric quantity tester and a test system; wherein the alternating current-direct current electric quantity tester is used for real-timely detecting electrical parameters relevant to an LED power source to be tested and analyzing and processing a detected signal correspondingly; the test system is used for determining an electric quantity signal collected when the variable electronic load is varied, synchronously reading a signal tested by the alternating current-direct current electric quantity tester, and correspondingly forming a power source analyzing test result file; the alternating current-direct current electric quantity tester is connected with the LED power source to be tested and is used for synchronously testing input current, input voltage, power and power factors of the LED power source to be tested; the LED power source to be tested can supply power to the variable electronic load; and the variable electronic load and the alternating current-direct current electric quantity tester are connected with the test system. The LED power source analysis and test system has a simple structure, is convenient to arranged, is simple and convenient to operate, has a good effect and full functions, and can be used for synchronously testing a direct current program control electronic load and an alternating current electronic parameters of the LED power source.

Description

technical field [0001] The invention belongs to the technical field of analysis and testing of power supply operating parameters, and in particular relates to an analysis and testing system of an LED power supply. Background technique [0002] With the use of solar LED street lights more and more widely, the problems that arise during its use have attracted more and more attention.
