FAQ

Patch LED light broken one, short circuit can use it?
Patch LED lamp LED wick is usually series, and a bad, can temporarily short-circuit, temporary use, because after short-circuit, this LED wick voltage will be assessed to other LED wick, accelerate other LED wick aging.The damaged LED wick needs to be secured as soon as possible.
Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?
If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.
What is the principle used in SMD LED lamp, should pay attention to what the problem?
LED white is the light emitting diode, a PN junction to the most important use of SMD beads is the heat, according to the different manufacturer beads, glue package is not the same, should pay attention to pre baking time and temperature, the latter should pay attention to the patch temperature, the most important is the price, many manufacturers in order to cost savings, internal chip used is too small does not meet the standards, support steal frugal material, with iron, the failure cycle shortened, LED lamp can not reach the ideal effect. Again, the LED supply current must not exceed the rated value, which is an important factor in damage to lamps and lanterns
SMD LED lamp working voltage?
Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage
LED light SMD LED package in what form, trouble you under the guidance of...
The LED chip has bumps and is welded to the PCB board using FLIP CHIP to packaging technology.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.
Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?
LED high power and low power, small white rated current and LED wafer, such as a chip is 20MA two 40MA.... High power 0.5W, 100-150MA, 1W, 350MA current rating in the relevant product specifications
How do led patches measure good or bad?
Use the two stage tube test of the multimeter, the red pen is connected, and the black pen is negative. If there is a bee, the sound is bad, and if the light is bright, it is good
What does patch LED light mean?
The screen is divided into standard lamp and patch type, the light emitting diode lamp is inserted into the circuit board, and the patch is a patch welded on the circuit board. Two light sources are not the same. If only light, not so clear.
