As far as street lamps are concerned, the ambient temperature of LED street lamps is not static. The range of use of LED street lamps determines that they are greatly affected by the environment. For example, if the temperature changes, the LED current will increase, the voltage will increase, and the LED current will also increase. increase. Long-term operation beyond the rated current will greatly shorten the life of the LED lamp. The LED constant current is to ensure that the working current value is constant when environmental factors such as temperature and voltage change, that is to say, the current in the LED street lamp is fixed regardless of the weather, thus ensuring the LED street light. It does not shorten the life due to power changes.
