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), 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,[link widoczny dla zalogowanych], a period of 1 minute,[link widoczny dla zalogowanych], amplitude of 1.5 cm, up and down,[link widoczny dla zalogowanych], left, before and after the three directions tests were 30 minutes, then remove the sample test,[link widoczny dla zalogowanych], the phenomenon should not be damaged, 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, 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.
