How to choose led street bulb
1 Adjust the operating voltage of the LED lamp to adjust the luminous intensity of the LED.
2 A small change in the operating voltage of the LED will cause a large current change. If the current exceeds the maximum current of the LED lamp beads, it will be burned. Therefore, the LED lamp must be powered by a constant current power supply.
3 High-quality LED lamp beads have a lifetime of over 1 million cycles and exceed any previous light source, so LEDs have a long life and durability.
4 Experiments prove that the LED power is lower than 50% of the rated power, LED heat will drop to 60-70%, the LED lamp temperature is low, the longer the light attenuation period (abbreviated as light failure), the longer the life of the LED lamp. long.
