Test Method: Plug trials. In the low-temperature conditions, the regulator voltage to 250V, switch three times, at intervals of not less than 8 seconds (an interval of 8 seconds is to be the capacitance of all the discharge lamps to reduce the mutual interference),[link widoczny dla zalogowanych], in the process , lamps should not be damaged, or they will be disqualified. E: vibration test. Main testing equipment: vibration test stand a number of tests: 10 packaging.
Test method: the test sample and pack it on the vibration test stand, the test frequency modulation in the 0. 5-5 Hz, a period of 1 minute,[link widoczny dla zalogowanych], amplitude of 1.5 cm, up and down, left, before and after the three directions tests were 30 minutes, then remove the sample test, the phenomenon should not be damaged,[link widoczny dla zalogowanych], or they will be disqualified. (BF-LD electromagnetic vibration table vibration table and the simulation of transport BF-SV Series) F: life test. Main Test Equipment: Power supply main test items: the number of normal working life test: 10.
Test Method 1: the lamp connected to rated voltage 220V, allowed to work, start working down the time until each lamp is damaged, note the time of termination, when all the lights damage,[link widoczny dla zalogowanych], find the average working time of light This is the life of the product. Test Method 2: based on the actual lighting products, to take the life of the aging accelerated methods (such as adding high-temperature, high pressure and frequent switching, etc.), according to the actual situation of the aging manufacturing special equipment.
