The progress of LED technology means that outdoor lighting has entered a new era. LED not only has high luminous efficiency, but also has long life, energy saving and environmental protection. Therefore, LED technology is used in street lamps, and LED street lamps are vigorously promoted. When choosing
LED street lights, you can no longer match the power supply to the street lights as before. We not only choose the power supply according to its power, but also configure it according to our actual needs. Let the LED street light manufacturers show you how to choose the power supply according to the power of the LED street light.
Constant current power supply is the first choice for
LED street lights. The calculation should be based on the specifications of the LED. The current and voltage of the LED of different LED street lamp manufacturers are different, and the lower the RF value and voltage of the LED, the better. General .V. If any, V is better than the former. The current is in mA.
, Then select the current according to the series-parallel relationship of your
LEDs, and the voltage of the constant current power supply will be automatically adjusted according to the number of LED strings.
, you need a low-cost design that can reduce the LED lamp beads and increase the current to achieve.
, if you require a stable and long life, press the normal current or a little less.
It is also worth mentioning that when choosing LED street lamp power supply, you must buy it from a regular LED street lamp manufacturer, and try to require brand power supply. Brand power supply is longer than ordinary power supply in terms of workmanship, materials and service life. Moreover, a brand power supply is not much more expensive than an ordinary power supply.
