Briefly Describe The Technical Requirements Of LED Street Lights
The LED street light project is not only affected by the global environment, but also by its industry specificity. LED street lamp power supply is the most important development of LED.
1. Why should the LED street light driver be constant? The characteristics of LED lighting materials determine that they are affected by the environment, such as temperature changes, LED current increase, voltage increase, and LED current increase. Exceeding the rated current for a long time will greatly shorten the life of the LED lamp. LED constant current is to ensure that its operating current value remains unchanged when environmental factors such as temperature and voltage change.
2. LED street lamp power supply working voltage Generally, the recommended working voltage of LED is 3.0-3.5V. After testing, most of them work at 3.2V, so it is reasonable to calculate by 3.2V. N lamp beads are connected in series with the total voltage = 3.2 * N.
3. What is the most suitable working current for LED street lights. For example, the rated current of LED is 350 mA, and some factories use it to do it, and the design is 350 mA. In fact, this work is very serious under the current heat. After several times For comparison tests, a design of 320 mA is an ideal attempt to reduce heat and convert more energy into visible light.
4. Wide-voltage LED street lamp drive In order to make the LED street lamp power supply within a wide range of AC85-265V input voltage range, the series-parallel connection of the lamp panel LEDs is very important. Do not apply wide voltage as much as possible, and can be classified into AC220V and AC110V as much as possible to ensure the reliability of power supply.
