Common problems and solutions of LED lamp
Adddate:2017-09-08 16:33????Hits:
1, the problem is caused by abnormal power supply:
01, check the power supply has no normal work, instructions light has not lit, if not lit up, please check the power supply, there is no connection;
Positive and negative power line 02, check whether the same lamp power supply is connected, there is no reverse, if any of the above problems, please be connected correctly.
2, LED lamp for voltage requirements:
01, nominal 3V LED, in fact, different colors have different requirements on the current, the current minimum are yellow, red, green, white, blue. Too much electricity will scorch the wick.
02, the use of 2.4V rechargeable batteries, yellow easy to burn, because even if the voltage is not large, but the current is too large, at random will still be burned.
03, when using the button battery, the battery voltage is 3V because the button though, but because the button battery discharge current is very small, so the 3V LED lamp will not be burned. Therefore, when using the LED lamp, should select the appropriate power, voltage and current attention.
04, the power supply, if not in line with the LED lamp rated requirements, need to install circuit is improved. The common resistance!
3, how to divide the light color of the braided LED beads:
In case of no power, it is recommended that a 3V button battery be prepared in order to facilitate selection at the time of purchase. The battery can be used to conveniently check what light the LED is emitting.
4, high power LED lamp burn reason:
01, the upper and lower two filament, our industry called gold wire, pure gold, to do conductive use, two positive, two negative, and really good products will have fifth lines, welded on the zener tube, play a protective role
02, the filament becomes shorter, has been very clear to tell you, you have been burned by high current lamp, equivalent to a circuit breaker
03. High power 1W drive current is about 350mA, the working voltage is between 3.2-3.6V. Please pay attention to it when using. Excessive current will burn the lamp
04, the general three 1W lamp aluminum substrate is about 12V drive, and there is no direct use of 220V, you see whether it is less a constant current source, or less a 12V driver power?
Reason 5, yellow LED lamp:
The reason why the outer seal of LED is yellow is mostly due to the mismatch between epoxy resin and curing agent, but it can not rule out too long baking time.
Solution: buy complete sets of outer sealing and solidifying agent, such as the Shanghai fine chemical model 800 or 2339 glue will not appear in this case, the other focusing on production management and control, strictly according to the work instruction operation, avoid baking time is too long or less, this is a good control of the situation.
6 reasons, LED lamp leakage:
When the equipment is out of order, the personnel do not wear the electrostatic Bracelet (if there is rope). Caused by improper electrostatic protection. Again in the course of packaging, welding line PAD welding deviation, and finally the quality of the chip itself hidden trouble.
7, LED lamp should be capacitive, inductive load problem:
In fact, the two are not, LED lamp is a grade two pipe, it requires a positive turn-on voltage can work, is generally 2-3.5V, in addition, the current size of the brightness can be controlled LED beads. It said LED lamp only converts electrical energy to light.
8, LED lamp pearl decline big reason:
01, the iron stent heat conduction is not good.
02, epoxy yellow.
03, the chip and stent contact is not tight enough.
04, chip attenuation.
