Led while product standards and testing methods can not be in the product development, but the product standards and testing methods should be followed as much as possible the progress of product design and development, [link widoczny dla zalogowanych] because the development of standards and testing methods for product development process itself is summary of discussions and review process, as long as basic conditions mature, product standards and develop more timely detection methods, the more they can reduce the product development process of blindness.
testing requirements in figure 2 connection. [link widoczny dla zalogowanych] figure 2 start the test circuit and test the connection process, follow these steps: click a sign of led control unit connected to the smallest led load. to control the output voltage control devices, thereare multiple parallel load, leaving only a minimal load.
at the same time, the measurement control devices shall not exceed the led maximum output current or nominal maximum output voltage. after completion of the measurement, disconnect the s1 and s2, wait 15 minutes before closing s1, [link widoczny dla zalogowanych] oscilloscope set above, and then closing s2, the valid values recorded at this time is the oscilloscope controls work after connecting the connection led module current and connection voltage should not exceed the led module is equipped with the rating (current and / or voltage) of 1.1 times.
