How long can the led blister signboard work normally under the working environment of about 40 degrees with three air conditioners? How much impact does it have on air conditioning?

The normal working temperature of led is generally allowed to be below 65 degrees, which is absolutely safe and has no influence on the service life. The service life of a single led can reach tens of thousands of hours. Usually, the reason why it doesn't work is caused by the driving circuit. When you install it around the outdoor unit of an air conditioner, you should mainly consider the heat dissipation of the outdoor unit. Poor ventilation may have a certain impact on the cooling effect.
