[Solar Light Factory School] Common Qu0026A of 3 Solar Lawn Lights (Picture)

Solar lawn lights have been widely distributed and promoted, but everyone still has many questions about it. What are the three questions that they often encounter? Let the solar lamp factory lighting editor answer these questions for you. 1. What impact does the advancement of the boost circuit power have on the solar lawn lamp LED light? Low-power solar lawn lights usually have a boost circuit. If a vibration circuit is selected, an inductance boost is used. Standard color code inductors are used for the inductance, and open magnetic circuits are used in the standard color code inductors. The magnetic flux loss is large, so the circuit power is low. If a closed magnetic circuit is used to make an inductive boost, such as a magnetic ring, the power of the boost circuit will be greatly improved. The characteristics of the LED are close to the Zener diode, the operating voltage changes by 0.1V, and the operating current may change by 20mA. For safety, the use of series current-limiting resistors under normal circumstances, the huge energy loss is obviously not suitable for solar lawn lights, and the brightness of the LED changes with the operating voltage, and the current must be actively limited, otherwise the LED will be damaged. Usually the peak current of the LED is 50-100mA. If the high-energy battery is reversely connected or the battery is unloaded, the peak voltage of the booster circuit may exceed this limit and damage the LED. 2. What are the packaging methods for solar lawn lamp batteries? Currently, there are two main packaging methods for solar lawn lamp batteries, laminated and glued. Laminating technology can guarantee the operating life of solar cells for more than 25 years. Although the glue is beautiful at the time, the operating life of the battery is only 1-2 years. Therefore, low-power solar lawn lights below 1W can be packaged with epoxy without excessive life expectancy. For solar lawn lights with regular service life, it is recommended to use laminated packaging. 3. What is the process of turning on and turning off the solar lawn lamp? Solar lawn lights turn on and turn off lights are the process of gradual dimming. On the one hand, it can add solar lawn lights to illuminate, and on the other hand, it can control the uniform output current of the battery by changing the flashing duty cycle, extending the operating time of the system, perhaps under the same conditions , Can reduce the power of solar cells.
