The invention relates to the LED product testing technology field and particularly relates to a temperature control method for an LED driver reliability acceleration test. The temperature control method comprises steps for the LED driver reliability acceleration test comprises steps of obtaining temperature of a component of an LED driver which needs to heat locally and an extra temperature increase under a condition that acceleration factors of each component of a tested LED driver are identical, adopting an ultraviolet light source to irradiate the component of the LED driver which needs to heat locally, using an infrared imaging instrument to test a surface temperature of each component of the tested LED driver, and adjusting the ultraviolet radiation intensity of the ultraviolet light source according to a step measurement result until a temperature requirement is satisfied. The temperature control method for the LED driver reliability acceleration test can perform local heating on components of multiple LED drivers synchronously while performing integral heating on the LED driver to accelerate aging, guarantees acceleration factors of the components of each LED driver are basically identical and thus improves accuracy of the reliability acceleration test of the LED driver.
