The invention discloses a sulfuration test method for verifying LED lamp bead anti-sulfuration technology. After sulfuration test, testing data deviation of each parameter of the LED lamp bead goes beyond the range of errors allowed; what's more, when a sulfurized LED lamp bead sample is placed under the microscope for observation, bottom of the LED lamp bead is found black obviously. According to the test method, validity and reliability of the anti-sulfuration technology are verified by way of sulfurizing the LED lamp bead which is treated with anti-sulfuration technology. The conclusion made after the verification of the method is that anti-sulfuration has no effect and cannot realize the function of anti-sulfuration; meanwhile, through verification of the method, authenticity and effectiveness of the anti-sulfuration technology are confirmed.
