Home to buy led desk lamp is broken? Can someone fix it?
First, let people to understand together what is LED lamp, LED lamp is with leds (Light Emitting Diode), namely, the desk lamp of light emitting Diode as light source, LED is a solid-state semiconductor devices, it can be directly put DianZhuan into light. LED lamps mainly on my desk, there should be seen! The led lamp is broken? First, what kind of degree, do you want to look bad if only desk lamp light bead is broken, not bright, it is resistance there is a problem, this will need to change the lamp bead and resistance. As for what's in it? This will still get the special repair shop to repair. If if is changing lamp bead, at the time it was bought on the manual of desk lamp, lamp bead size and style are consistent, avoid safety accident. Led lamp is broken, there are one thousand emergency, they cannot rule out, but they can use opportunely coup to solve one by one. Led desk lamp is broken what can I do the second case is all of the lights, less bright than before, that means that may be a desk lamp internal battery is broken, need to replace a battery at the same time also check link and the power of the thread is broken, if it is a wire is broken, change it, this is unable to repair, no equipment, and can't find the repair method, the solution only replacement. Under the condition of led desk lamp is broken what can I do, actually is a small matter.
Led desk lamp is broken happened to do a fourth most often is the lamp not bright, the bright part is divided into light, or is not all bright, if the part is not bright, leads to such a situation has a lot of, or the circuit in the process of transportation, short circuit, or the voltage lead to light bead is broken; Or transmission in the process of welding is not good, if so, in the case of cut off the power the lights bead is not light that were removed, ready to two-way plug into two line.
There are also a lot of emergency, at present is that several kinds of the most common, actually what led desk lamp is broken, this also need careful maintenance and care for at ordinary times, avoid to touch water, avoid excessive lamp switch frequently, it will affect the use of lamps and lanterns, anyhow how bad how to solve, most people do in led desk lamp is broken, is discarded, to buy one, this way is not no, since the advocating environmental protection, can repair to reoccupy is also a very good treatment.
Open the lamp plate, with a digital multimeter measure the lamp bead, bad to use soldering iron to remove, in a better LED lights up welding bead, pay attention to is the cathode, reset can! If no suitable LED lamp bead, can use a other LED lamp bead, if you don't have LED lamp bead can be replaced light-emitting diode tube, pay attention to is the cathode. After electrify leds light is so bright before, not as bright as LED lamp bead. Leds can be in other waste circuit board down a phone charger, or in the place such as waste charging treasure, the computer panel, vcD can be on the front panel, ready to do it, will shine again.
Led lamp production line is simpler, less complicated, general physics students will know their internal circuit structure, can also according to their own learning physical knowledge for repair, is a master of his own academic degree. If not, it may as well borrow coup. Led desk lamp is broken do next the third case is the light switch to normal, the general desk lamp can have between dark and light switch, if so, could be the governor, the interface carefully check, is there any loose or not, whether the governor is out of order, if the governor bad needs to be replaced, just stepping up strong interface
