What aspects do you need to do to detect LED street lights? LED street light is an important infrastructure in cities and towns, and as an important government infrastructure, it is conducive to the living needs of the people. LED street lights also need to be tested every time, which parts to detect, to see what Xiaobian share:
Test the components of LED street lights
1. Test the controller:
The controller's red light indicates that charging is underway, and the red light flashing indicates that the battery is full and the controller is charging with a small pulse current. The yellow light of the controller indicates that the battery has lost power and cannot be illuminated normally. At this time, if the battery line is disconnected and then reconnected, the light will be on. At this time, the controller detects that the battery capacity rises after a day's charging, not the floating voltage of the battery.
2, battery detection:
If the battery is charged and discharged under normal conditions, it is normal. For example, if the voltage is above 12V during detection, and the voltage drops within a short time after the load is connected, the battery is damaged. In addition, it can be the battery in the waterproof shell caused by the short circuit of the positive and negative terminals caused by unstable voltage, usually high voltage is high when low, due to the water caused by the battery discharge too much voltage to 10V below, this time the battery can be used normally after the normal small current cycle charge and discharge, if not normal use, it needs to be replaced. Lead acid batteries in three years due to the decline in capacity will cause the daily solar LED street light turn-off time in advance or rainy days reduced, which is a normal phenomenon.
3. Detection of solar panels:
If the connection of the solar panel is not very strong, it will cause the solar LED street lamp to be charged normally, which is usually manifested as voltage without current. This phenomenon is that the line of the panel is not connected, and the data can be detected directly with the voltage and ammeter after the black electrical cover behind the panel is opened. If there is no current detected directly from the aluminum moor of the panel, it means that the panel has a problem and needs to be replaced.
4, LED light source detection:
The light source can work normally under normal battery voltage, such as the solar LED street light is not bright, you can directly connect the positive and negative electrodes of the light source to the positive and negative electrodes of the battery for detection, such as the light source can be lit up to show that the light source is good, the controller did not supply power to the lamp. So you have to wait until the battery is fully charged again; It only works if the voltage rises. If the lamp is directly connected to the battery, the lamp is not bright, indicating that there is a problem with the light source, which requires timely contact the manufacturer for replacement.
What aspects do you need to do to detect LED street lights? Detection of LED street lights do not need to be simple at all times, generally have professional technicians regularly test and maintain, general product quality will not appear any problems, regular maintenance testing for safety, Liyang lighting professional production and sales of LED manufacturers for you.
