Cold and hot attitude photoelectricity testing arrangement of LED

The utility model provides a cold and hot attitude photoelectricity testing arrangement of LED, including the test box, be used for circuit board, power control module, light detector, temp. Control module and the host computer of welded connection LED's pin, be equipped with the control by temperature change probe that is used for surveying LED pin temperature among the temp. Control module. Theutility model discloses weld LED on the circuit board, make things convenient for power control module to control LED's power sum voltage, through setting up temp. Control module, pop one's head in through temp. Control module's control by temperature change and survey the temperature of LED's pin to confirm the temperature of LED work, surveys accurate, and the time control LED operating temperature, can survey LED's luminance simultaneously through light detector, and through host computer analysis processes, in order to obtain luminous efficacy and the voltage parameter that correspond of LED under each temperature
