| titleOfInvention | LED lamp test circuit |
| abstract | The utility model discloses a LED lamp test circuit, which belongs to the technical field of test circuits and comprises the following components: the system comprises a plurality of program-controlled constant current modules, a plurality of current-controlled constant current modules and a plurality of voltage-controlled constant current modules, wherein the program-controlled constant current modules are used for providing constant current for each loop to light the LED and isolating and collecting VF on the MOS; the short circuit scanning module among PIN is used for realizing a short circuit testing function of PIN, and is connected with the program-controlled constant current modules; the constant current reference module is used for providing voltage reference for each constant current module and is connected with the program-controlled constant current modules; the voltage-resistant module control signal and switch feedback output module is connected with the constant current reference module; and the DCDC module is used for providing a corresponding voltage source for the whole circuit and is connected with the program-controlled constant current module. |
