How to wire solar led street light?
In the case of solar led street light wiring, ensure the output of constant current power supply, because the LED itself must be protected by constant current power supply or overcurrent according to the method, otherwise it will not work normally. Leds Usually, the way to choose a lamp is to add another led driver to achieve a constant current power supply for the led, but this must result in a loss of output power, resulting in more power consumption by adding a separate LED driver. The street lamp gradually outputs the current and starts working within the set time range. Power adjustment: Adjust the output power in the application. The chroma of the LED lamp can be manipulated by adjusting the output power.
1. Determine the installation position of street lamps. According to the engineering drawings and the geological environment survey on site, the installation position of the street lamp should be determined according to the distance of 40 meters between the street lamps in the non-shaded area on the top of the street lamp. Otherwise, the installation position of the street lamp should be replaced appropriately.
2. Solar panels For perishable goods, the customer is not allowed to place lifting objects on them during installation. During the installation of solar panels, we should make clear the group outlet behind the solar panels. The sheathed wire must be stripped off when wiring. Multi-core copper wires used in solar led street light must be tightened during use. Not allowed to expose the group out of line thorns. If not properly controlled, there will be a short circuit fault, the diode will burn.
3, in the excavation of the deep foundation pit to build battery boxes, buried rechargeable batteries. If the deep excavation is not wide enough, everyone will dig again, and there is enough interior space to accommodate the battery box.
4. When installing the solar led street light source, two wires are drawn from the lamp port for the convenience of installation personnel. According to different lamp port styles, the wiring mode is different, but the positive and negative terminals are the same. When wrapping with tape, pull gently with your hand to avoid loose connection, surge and fall.
5. Concrete pouring of street lamp foundation embedded parts: in the foundation pit excavation one meter deep, the pre-welded embedded parts are placed in the foundation pit, one end of the wire hose is placed in the middle of the embedded parts, and the other end is placed in the embedded battery. The embedded parts, roadbed and road should be kept at the same level.
The solar led street light control panel has four wires that match three machines and devices with solar panels, rechargeable batteries and street lights. The details are as follows.
General network cable connections refer to the following connections:
Bright red wire: positive induction wire connecting all mechanical equipment;
Dark blue line: negative electrode of solar panel;
Gray black line: rechargeable battery negative pole;
Green line: street lamp negative pole;
solar led street light connection mode:
Connect the positive electrode of the panel, the positive electrode of the rechargeable battery and the positive electrode of the street lamp to the red bar of the control panel, then connect the negative electrode of the solar panel to the green wire, the negative electrode of the rechargeable battery to the black bar, and finally the negative electrode of the street lamp to the emerald green.
Red bar: positive level of all mechanical equipment;
Green line: negative pole of solar panel;
Black bar: negative electrode of rechargeable battery;
Green: negative pole of street lamp;
