YUANNENGJI Manik lampu LED memerlukan voltan rendah DC untuk berfungsi, 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 ialah peranti semikonduktor voltan rendah yang agak sensitif. Bekalan kuasa pemandu yang layak mesti mempertimbangkan secara menyeluruh faktor seperti kadar penukaran, ketepatan arus yang berterusan, hayat perkhidmatan, dan keserasian elektromagnet.
1: Terdapat bintik-bintik hitam yang jelas pada permukaan manik lampu yang terbakar. Hanya sambungkan wayar ke belakangnya ke litar pintas; atau gantikan manik lampu baru untuk menyelesaikan masalah.
2: Manik lampu LED adalah bahagian penting lampu LED dan badan utama cahaya. Oleh kerana manik lampu LED disambung secara bersiri dan kemudian secara selari, apabila salah satu manik lampu terbakar, keseluruhan lampu LED mungkin tidak menyala.
3: Pereputan cahaya merujuk kepada kecerahan sumber cahaya yang semakin rendah dari semasa ke semasa, terutamanya lampu pijar dan lampu penjimat tenaga yang sering kita gunakan, which may not light up after use.
4: The light decay of the LED itself causes the brightness to dim. Light decay refers to the light source, such as various lamps and light sources, which will become lower and lower in brightness over time, terutamanya lampu pijar dan lampu penjimat tenaga yang sering kita gunakan, which may not light up after use.
5: Chip problem: When the chip is damaged, the brightness of the LED light will decrease, which is what we call dimming. In severe cases, the entire LED light will not light up. Minghong uses original imported COB high-brightness chips to reduce light decay from the root, and the light emitted is uniform and comfortable, more transparent and bright, with a long service life and a three-year warranty.
6: Problems caused by heat dissipation. If the heat dissipation effect is not good, the light source will age. The better the heat dissipation performance, 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. Secara umumnya, 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.
