LED to shoot the light is not very bright, or where the flash is broken?
This is bad the lamp itself, drive the largest than columns, the second is the lamp bead, driving power and light board and a matching problem will also have this kind of like now, that is to say driving power source or lamp plate lamp bead one appeared quality problem, does not match. As you mentioned, if it is in the driver is the same, that is the lamp bead light board has a problem. Return to factory maintenance.
Flash isn't lamp bead bad, this should be a drive and lamp does not match, how much is your driver output volts, current how many, what size of lamp bead, when you load series and form? I can assure you that your lamp voltage than you drive on the output voltage
Two questions inside shoot the lamp to lamp bead is leakage can be determined, at first, no flash is used less, use a long time, and with the leakage of electric lamp bead, commonly known as the internal short circuit, affect the driver's working status and life, lamp bead brightness is not enough, is the droop, lamp bead is not good, the greater the droop. Suggest you to return to the manufacturer, or manufacturers a replacement.
Here's why: 1, the voltage is not enough, need to use multimeter to measure voltage conform to shoot the rated voltage. 2, poor contact: check whether the terminal is loose or have foreign body, make its wiring is good. 3, connection error: LED lights must be in accordance with the wiring diagram connection, not in series.
I will do it for you, I myself solved the same problem with you, first determine in power, is the drive you say is useless, it sure is a problem of lamp bead, the lamp will be unwrapped LED lens until you show bead, flat on the table, the lamp lights up, access to electricity, you get a wire, wire stripping out at both ends of a nod to ready you can use this wire to short circuit test lamp bead, is to use this wire ends to point in a lamp bead on two feet, a light bead lamp beads point, until the point in a grain of lamp bead suddenly the lamp height is normal, so congratulations you, you find the bad, take it with a thin copper wire electricity ferrochrome in bad light bead welding of two feet on the KO, then there may be some friend to ask, if broken two or three grain of lamp bead to do? , it doesn't matter, you when I come back again hair a question answer just forget to summarize, why w leds will appear such circumstance, because this dozen grains is in series with the lamp bead, so a single bad overall don't bright
