YUANNENGJI LED чийдэнгийн бөмбөлгүүдийг ажиллуулахын тулд тогтмол гүйдлийн бага хүчдэл шаардлагатай, but the mains electricity we usually use is AC high voltage (AC220V). To convert the mains electricity into the electrical energy required by the lamp beads, a device called “LED constant current driver power supply” is needed. As long as the parameters of the driver match the lamp bead board, it can be powered continuously and used normally. Because the LED itself is composed of lamp beads, if one or part of it is not lit, the entire lamp will inevitably dim. Lamp beads are generally connected in series and then in parallel – so if a lamp bead burns out, it may cause a batch of lamp beads to not light up.
One of the functions of the driver is to provide a constant current and a stable power supply environment for the LED lamp beads. LED is a relatively sensitive low-voltage semiconductor device. A qualified driver power supply must comprehensively consider factors such as conversion rate, constant current accuracy, service life, and electromagnetic compatibility.
1: There are obvious black spots on the surface of the burnt lamp beads. Just connect a wire to the back of it to short-circuit; or replace the new lamp beads to solve the problem.
2: LED lamp beads are an important part of LED lamps and the main body of the light. Since LED lamp beads are connected in series and then in parallel, once one of the lamp beads burns out, the entire LED lamp may not light up.
3: Light decay refers to the brightness of the light source becoming lower and lower over time, especially the incandescent lamps and energy-saving lamps we often use, хэрэглэсний дараа асахгүй байж болно.
4: LED-ийн гэрлийн задрал нь өөрөө гэрэлтүүлгийг бүдгэрүүлэхэд хүргэдэг. Гэрлийн задрал нь гэрлийн эх үүсвэрийг хэлдэг, төрөл бүрийн чийдэн, гэрлийн эх үүсвэр гэх мэт, Энэ нь цаг хугацаа өнгөрөх тусам гэрэл гэгээ багасах болно, especially the incandescent lamps and energy-saving lamps we often use, хэрэглэсний дараа асахгүй байж болно.
5: Чиптэй холбоотой асуудал: Чип гэмтсэн үед, LED гэрлийн тод байдал буурах болно, Үүнийг бид бүдэгрүүлэх гэж нэрлэдэг. Хүнд тохиолдолд, LED гэрэл бүхэлдээ асахгүй. Минхонг үндэснээс гэрлийн ялзралыг багасгахын тулд импортын анхны COB өндөр тод чип ашигладаг, мөн ялгарах гэрэл нь жигд, тухтай байдаг, илүү ил тод, тод, урт хугацааны үйлчилгээний хугацаа, гурван жилийн баталгаат хугацаатай.
6: Дулаан тархалтаас үүдэлтэй асуудлууд. Хэрэв дулаан ялгаруулах нөлөө сайн биш бол, гэрлийн эх үүсвэр хөгширнө. Дулаан ялгаруулах чадвар сайн байх тусмаа, the lower the working temperature, the smaller the light decay, and the longer the life of the LED lamp.
7: The probability of fluorescent lamps dimming is much greater than that of LED lamps, because fluorescent lamps are heated by the gas in the lamp tube to emit light. When the heat light tube is aged or damaged, the brightness of the fluorescent lamp will be insufficient due to the reduction of internal gas or poor sealing. Ер нь бол, this problem is mostly caused by damage to the lamp beads. You can remove the lamp board to see if there are black spots on the lamp beads. If there are, the lamp beads are broken. If the driver is broken, the driver board needs to be repaired.
