Will the light turn on if the positive and negative poles are reversed? What should I do?If it was an ordinary light bulb, it usually did not need to be divided into positive and negative poles. As long as the circuit was connected in the opposite direction, it would still emit light. However, there might be situations such as open circuit and reverse breakdown, but there would not be a short circuit (usually with a current limiting resistance). Different situations needed to be analyzed in detail. If it is an LED lamp, when it works under the direct current power supply: if the direct current power supply is less than 5V, even if the positive and negative poles are connected in reverse, there will be no reverse breakdown; if the direct current power supply is between 5V -30V, the positive and negative poles are connected in reverse, the situation is complicated; if the direct current power supply is above 30V, the positive and negative poles will be broken down in reverse.(However, this situation is rare, because usually the LED power supply will not exceed 30V); If the LED is connected to an AC circuit above 30V (such as a 220V AC power supply LED indicator circuit), the LED will definitely be broken down in the negative half cycle of the AC power supply.
If you find that the positive and negative poles of the lamp are reversed and do not light up or there is a problem, you should first cut off the power supply and then connect the positive and negative poles correctly. For bulbs or LED lights that may be damaged, it is necessary to check whether they can still work normally. For example, the LED lights may need to be checked whether they are broken. If they cannot work normally, they may need to be replaced.
