The testing rules of lighting product

A: High temperature test
The main test equipment:thermostat、thermometer、pressure regulator、voltmeter and the clock
The main test project: High temperature and low pressure start、The high temperature operation is safety
Number of tests: 10
The test method: Put lamps under test in the constant temperature box,connection circuit,adjusting the output voltage of voltage regulator till

180V,open the illuminant of constant temperature box,set the temperature at 60 ℃, open the power supply of luminaries when the temperature in

the cabinet up to 60 ℃, observe the luminaries working correctly or not, then adjust the voltage regulator till to 250v, let it work for 24 hours, observe

the results. If occur luminaries damage, material thermal deformation and abnormal phenomena,therefore the experiment is unqualified.
B: The test start of high temperature and high pressure
The main test equipment:thermostat、Thermometer、pressure regulator、 voltmeter and the clock
The main test project: High temperature startup performance and reliability
Number of tests: 10
The test method: Then follow the above test, under the condition of high temperature, adjusting the voltage of voltage regulator till 250V,Switch 3

times,each times interval is not less than eight seconds,in the process, the luminaries should not be damaged, otherwise will be regarded as not

qualified.
C: The low temperature test
The main test equipment:Power supply、Low temperature box、thermometer、pressure regulator、voltmeter and the clock
The main test project: Low temperature start
The test method: Put luminaries under test into the low temperature box,connect the rated voltage power supply, the temperature is set in -15 ℃, when

the temperature of cabinet inside drop to -15℃ then keep 2 hours again, after let the luminaries fully cooled, open the luminaries power supply, observe

the results, if occur luminaries damage, can’t start or abnormal phenomena,therefore the experiment is unqualified.
