YUANNENGJI Өөрийн онцлогийн улмаас, LED must be controlled by technical means to achieve constant current or current limiting, otherwise it cannot be used normally. Common LED lights all achieve constant current of LED lights by adding a driving power supply, but this drive accounts for about 10%-20% of the total power of the entire lamp. When calculating the power of the solar panel and the battery capacity, an additional 10%-20% must be added to meet the power consumption brought by the drive.
Ordinary LED solar light controllers can generally only be set to shut down after 4 hours or 8 цаг, гэх мэт., which can no longer meet the needs of many customers. The industrial version of the controller can be divided into 3 time periods, цаг хугацаа бүрийн хугацааг дур мэдэн тогтоож болно. Ашиглалтын орчноос хамааран, цаг хугацаа бүрийг унтраагдуулсан байдалд тохируулж болно.
Нарны гэрлүүдийн дунд, LED гэрлүүд импульсын өргөнийг зохицуулснаар өөр өөр хүчийг гаргахад хамгийн тохиромжтой. Импульсын өргөн, урсгалыг хязгаарлаж байхдаа, LED гэрлийн бүх гаралтын үүргийн циклийг тохируулж болно. Жишээ нь, нэг 1W LED 7 strings and 5 parallels is placed at night, with other of 35W LED lights. The power is тус тусад нь шөнө орой болон өглөө эрт тохируулна, Шөнө орой 15W, өглөө эрт 25W гэх мэт, and the current is locked, ингэснээр гэрэлтүүлэг шөнөжингөө нийлэгдэж болно.
Ухаалаг гэрэлтүүлгийн хянагчийг програмчилдаг гэрэлтүүлгийн хянагч гэж бас нэрлэдэг, which means that the lighting program of the controller can be modified according to the needs of users, such as modifying the speed, time, pattern, synchronization, asynchronous, гэх мэт. of the flashing light.
Using a stable and reliable 51 single-chip microcomputer as the hardware control core, equipped with upper computer software, the light can be edited and modified, program downloaded, upgraded to computer USB interface communication, гэх мэт., which greatly improves the convenience of the controller. The supporting software can edit and download the compiled control program at will, and has a unique software preview function, which is convenient for modifying and debugging the lighting effect.
The positive and negative poles of the power supply are GND and MODE wires. Now the controller output has four holes. Эхлэх, see if the hole marked with the number 10 is in the middle or at the edge of the four holes. If it is at the edge, then you connect the positive poles of the three LEDs to this hole together, and the negative poles of the three LEDs to the other three holes together. If the number 10 is in the middle, connect the positive poles of the three LEDs to three holes of the same size and close together, and connect the negative poles to the holes on the edge.
The LED solar light controller accounts for a relatively low cost in the LED solar street light system. It seems to be an invisible little thing, but it plays a big role. If the wrong choice is made, the overall stability and life of the system will be greatly reduced. A more mature controller can reduce the overall cost of the system through its functions and achieve the purpose of cost saving.
