Reliability design, by definition, that is testing whether the product user to use a reliable testing technology. The test technique using the success of the quality of the product has a significant effect, which implement the product throughout the design and production process. When an indoor lighting products are designed, it's life how long? How bad can an environment (such as high temperature, low temperature and vibration, etc.) to run? Manufacturers must first be aware of the experiment. Then, using the elements included in the manual to remind users to a number of precautions to avoid damage due to improper operation user products. Here are some reliability tests on simple methods and projects. Lighting product reliability test items mainly: A: high-temperature test B: the impact of high temperature and pressure start test C: low temperature test D: low-temperature high-pressure shock start test E: Vibration Test F: Life Test G: aging test H: small scale I: pilot. Here are just the use of these items. (Rated voltage of 220V for example) made them part of the equipment required. A: high-temperature test. Test Method: tested lamps into the thermostat, connect the circuit, the voltage regulator's output voltage to 180V (voltage regulator power supply only to the tested light), turn the power incubators, the temperature set at 60 , when the temperature rose to 60 box opens when the lamp power supply, observe the lamp is working, then the regulator rose 250V, allowed to work 24 hours, observe the results. In case of light damage to materials, such as abnormal heat deformation of the experiment when the failure. B: the impact of high temperature and pressure start test. Test method: connect trials. In the high temperature conditions, the regulator voltage to 250V, switch three times, each time interval of not less than 8 seconds (an interval of 8 seconds is the capacitance to be full discharge lamps to reduce the mutual interference), in th e process , lamps should not be damaged, or be disqualified. C: low temperature. Test Method: tested lamps into the cold box, connect the circuit, the voltage regulator's output voltage to 180V (voltage regulator power supply only to the lamp under test), open the cool box and power supply, the temperature set at -15 , when the temperature dropped to -15 inside the time to remain two hours to allow light to cool, open the lamp power supply, observe the results. In case of light damage and other abnormalities could not be activated when the failure of the experiment. (Bell brand constant temperature and humidity box BE-TH Series) D: low-temperature high-pressure shock start test. Test method: connect trials. In the low temperature conditions, the regulator voltage to 250V, switch three times, each time interval of not less than 8 seconds (an interval of 8 seconds is the capacitance to be full discharge lamps to reduce the mutual interference), in the process , lamps should no t be damaged, or be disqualified. E: vibration test. Test Method: Test sample packaging, on the vibration test stand, the test frequency modulation in 0.5? 5 Hz, 1 minute period, amplitude of 1.5 cm, in the up and down, around, around three directions test were 30 minutes, then remove the sample test phenomenon should not be damaged, or be disqualified. (BF-LD electromagnetic vibration table vibration table and the simulation of transport BF-SV Series) F: Life Test. Test Method 1: the lamp connected to rated voltage 220V, allowed to work, note the start of working hours, when each lamp is damaged, note the time of termination, when all of the lamps is damaged, find the average working time lighting This represents the product life. Test Method 2: based on the actual lighting products to take the life of the aging accelerated methods (such as high temperatures, high pressure and frequent switching, etc.), based on the actual situation of the aging equipment manufacturer dedic ated. G: aging test. Test methods; to first voltage to 250V, turn off the power, then the aging of Taiwan products installed, switch three times, each time interval of 8 seconds, then power off, then voltage to 170V, power observation, and finally the voltage transfer to 250V, 2 hours after the aging, the switch 3 times at intervals of 8 seconds, the end of aging. Over the course of the experiment were found to the problem of substandard products, need of repair.
