Zusammenfassung: | The invention discloses a method for rapidly and effectively detecting aging, and relates to the technical field of LED lamp aging detection. Comprising the steps of LED lamp bead sample selection, LED lamp bead sample preliminary detection, LED lamp bead overcurrent detection, LED lamp bead aging detection, LED lamp bead high and low temperature circulation detection, LED lamp bead high and constant temperature aging detection and LED lamp bead subsequent spot check detection. LED lamp beads are randomly selected from a plurality of LED lamp bead finished products according to different fields of colors, models, materials, power and the like, and 100-150 samples are selected from each group in the same field to ensure that the detection cardinal number is large, so that the detection accuracy is ensured, the authority of a detection result is ensured, and by adopting a high and low temperature cycle detection method, the detection efficiency is improved. The LED lamp bead is placed in an environment with alt |
