LED lamp, adjustable light, new to buy less than a week; Strip, it took more than 4 years. This morning on the strip, light will flash. To strip of the others will be fine. But the same old jack plug in the computer, but everything is normal, but the strip will issue "hissing" sound. Supposedly the lamp power is smaller than a computer, this is how to return a responsibility? I think baidu has said strip contact.
You have the phenomenon of poor contact strip inside It is ok to exclude poor contact
Used for strip after a long time, the contact piece there is deviation between, the plug of the lamp and the computer plug, its size and shape is little different, because of poor contact, slight of spark and arc, resulting in the "hiss" noise. Computer power supply is switching power supply, its adaptation wide voltage range and unstable power supply also can make the normal operation of the computer, and LED bulbs have unstable voltage, because the internal circuit has energy storage component, coupled with its low power consumption, and induced voltage, flashing would happen. Recommend replacing strip.
Lights flash that strip poor contact, the lamp power is small, so can't hear hissing "sound, the computer power is relatively larger, current is big, hissed." sound that strip poor contact; If you have the tools to open the strip to see whether the contact deformation, the whole connection piece, make can remove plug well, your problem is solved.
