led solar street light project is not only affected by the global environment, but also has its industry specificity. led solar street light power supply is the more important development direction of led.
1. why led solar street light driver should be unchanged? led lighting material characteristics determine its impact by the environment, such as temperature changes, led current increases, voltage increases, led current increases, etc.. Long time over the rated current work will greatly shorten the life of led lights. led constant current is to ensure that its operating current value in the temperature, voltage and other environmental factors change to remain unchanged.
2. led solar street light power supply working voltage Generally speaking, the recommended working voltage of led is 3.0-3.5V, after testing, most work at 3.2V, so according to 3.2V calculation is reasonable. . n lamp beads in series, the total voltage = 3.2 * n.
3. what is the more suitable working current in led solar street light? For example, the rated current of led is 350 mA, and some factories use and design for 350 mA. In fact, in the current heat, this work is more serious. After several comparison tests, the 320 mA design is an ideal attempt to reduce heat and convert more energy into visible light.
4. In order to make the led solar street light power supply work in a very wide AC85-265V input voltage range, it is more important to connect the led panels in series and parallel. Try not to add wide voltage, can be divided into AC220V and AC110V to ensure the reliability of power supply.
