Do not understand electronic circuits, lamp repair is very simple, usually bad lamp, the circuit board is broken, then there are bad switch, plug broke, poor contact wire and so on. . . . If you do not know the circuit, it is recommended to buy two, a spare, so as not to accidentally ruining. Thank you! !
Many buyers friends asked us, I bought your desk plate, can not use this in my desk lamp above, we can guarantee that: as long as your original board 2 lamp into the outlet 2 (that connected the original lamp board above the line, a total of only four lines). And lamp power of between 7W --- 27W. Then we will be able to directly use this board, do not change elsewhere. Some people will ask how long can buy our plate, for how long depends on the quality, not blowing out, I'm on my quality of confidence. General operating problems buy back if not damage the circuit board, the one after lighting quality is very stable.
The quality of the lamp is generally look at the head of the plastic tube and tube rupture is serious black, black and can not be broken, as well as the eyes can not see the problem, such as tube leaks, broken inner filament, lamp capacitance bad (that is colored red or Yuan two feet), we have a bad capacitor sent, please rest assured that this lamp is bad bad repair, it is necessary to replace. When you find power after the lamp head a little red hair, this time may be bad capacitor and lamp bad lamp, the circuit board is good. Some bad circuit board can be seen that some can not see, mainly to see the fuse and resistor have no bad marks.
Inspection methods provided thanks customers: two needles lamp bad lamp pins judging method: turn on the light plastic seat foot, you can see inside the structure and four needle-like, just to hide the capacitor in the lamp foot, only two leads lines. At this point you can use four-pin lamp judge good or bad way, measured with a multimeter
Tip: red is positive and the other end connected to the two lines lamp!
Lamp repair tips: Lamp board is connected all the wires, the first open lamp switch, and then plug the power cord into what 220V, just pay attention to insert it, the best power-on time of less than 2 seconds, the shorter the better, preferably one second clock time. Look at the lamp is bright look, if we can look bright, congratulations, lamp plate repaired. . If you do not look bright, it is necessary to re-examine switches, wires, tubes, etc. are normal, until you find the problem re-energized for 1 second try, or if the lamp is broken, it will burn long power circuit board. If the lamp is not broken, then the question mark is still rare, but this method please be sure to keep in mind, when did repair lights. Otherwise, the money did not fix also affect the mood lamp oh.
[Note: this baby photographed after the re-use if the buyer himself under the premise does not use, do not take yourself recommend, it is recommended to find a professional staff to help you connect later. In order to avoid the premise of non-technical, to the board burned. (The board has a test at the factory, some of the buyers themselves improper installation or improper operation of the board is burnt out. Said that the quality of the board), please understand that we look a little, are puerile, we definitely do not bad It will be shipped. ]
Usually bad lamp, capacitor unworthy, pick the wrong line, or are burned fried, use caution. Immediately burning the lamp or capacitive bad bad ...
The following are the customers to share experiences, the point does not shine can take a look:
Customers to share experiences: not this capacitor lamp will not light, because only 100V DC voltage
Rectifying plate and output capacitor, the voltage pulse to above 200V, capacitance and to good, some light will shine, because the lamp parallel capacitor will reduce the pressure drop, cap lamp near the bad capacitor capacitance can also play a role, and not bad on a capacitor safer
Some old-fashioned lamp in the tail lamps and a capacitor, for the town board.
27w lamp filter capacitor is 250V.6.8uf. Replaced 250v.10uf, the rectifying plate and the capacitor, the oscillation transformer Bibi had a large file on the line, the oscillation transformer also big 0.2 or more than the original, can be pushed 7-32w
Manufacturers Re: shunt capacitance does good for lamps, thus reducing the filament current, increase lamp life, but the parameters must be reasonable for the job, not just added, large capacitance, and sometimes difficult to start the lamp, particularly cold days .
If the lamp capacitance is 682, plus a 682, might not bright spot
Capacitive lamp itself, increase the capacitance of the circuit board is not very good, that the lamp may be old-fashioned lamp ballast,
There are no neon bulb inside the capacitor, it is more suitable.
To a four-wire line: that the four stages, divided into two groups, two from each line connected to the capacitor.
(Four outlet tube leads into two groups, according to the general color or wires and together, the two groups from each of a line connected to two capacitors foot rest tube drawn two lines meet us on board a white line it)
Learn talent photographed Oh, we do not understand technology, please understand.
Tips: Because manufacturers rectifying plate is sometimes not the same batch, individual original color and image a little bit different, does not affect the quality, pro ease of use.
