Abstract
A device for testing a lighting device including a plurality of light emitting diodes (LEDs) and an LED driver configured to drive the plurality of LEDs to emit light includes a camera configured to image a surface on which light output by the LED lighting device is incident, and generate image data corresponding to an output of the LED lighting device; and a controller configured to compare the image data with a reference condition, and in response to the output of the LED lighting device deviating from the reference condition, control the LED driver to modify brightness of at least a portion of the plurality of LEDs.
