Anonymous users2024-01-23The LED fluorescent lamp currently produced by our company, in the test process, it was found that the DB3 triggers the diode to start after cooling, which is not necessarily the reason for BD3. Try to check the value of the energy storage capacitor and the current limiting resistor coming from the power supply, and the withstand voltage.

Anonymous users2024-01-22For such a two-color LED lamp, if one of the colors is not lit, the first thing to see is whether the group of LED light sources that are not lit is not well wired, or the lamp beads are black and damaged. If not, then the probability of failure of the LED driver is very high, and it is recommended to find the LED driver with the same specifications for replacement. If the LED light source is black and damaged, then both the light source and the LED driver must be replaced.
The living room lamp drive is generally not rotten, basically the lamp beads are rotten, which should be connected in series, so the rotten one will affect that group + build a stool + check carefully + whether there is a lamp bead burned + the naked eye can basically see the gold wire burned off and blackened + a small black spot + as long as there is a black spot is burned + multiple light strip series circuits are generally burned several + the whole half (half is generally 5-6 light strips will not light up, and the living room headlights are generally controlled by two groups of ballasts + so only half is not lit).
If the circuit voltage is stable and normal, it is recommended to change to another brand of lamp.
No need to buy a new one, show you a way.
With this design, you can see that this single is divided into two halves for power supply, half is controlled by a rectifier, and the other half is broken, it must be a problem with the rectifier, or the connection failure of the entire light strip, you can replace the light strip or replace the rectifier, and the price is relatively cheap. >>>More
Big brother, this problem, it depends on how long you have been buying, the warranty is new, if it is installed, it is free of warranty, I don't know other people's manufacturers, a combination of LITE brand yes, we have installed them for three years without any problems, until now.
The voltage required for LED lights is particularly low, so the emitters are connected in series, so one is broken and the other is not lit.
