FAQ

The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
Shunt split current series split voltageIs your single lamp voltage rated voltageIn addition to the red and green LED lights, the voltage is between 2 and 2.4, and the other colors are 3 to 3.6V
What, in what way do I shunt the LED?
The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.
How to detect LED SMD beads
The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.
How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you
You can also use the ohmmeter's ohmmeter. To dial multimeter, to "ohm X1" file, the light emitting diode when the red pen is connected to the positive terminal of SMD LED, the black probe is connected to the negative terminal of SMD LED.
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 are the storage requirements of SMT patch LED (LED)?
Moisture-proof packing- anti SMD LED in the transport and storage of moisture absorption, SMD LED shall be placed in sealed moisture-proof bag, inside put damp proof agent for protection, and placed the humidity humidity SMD display card packaging bag.
Patch LED features
The principle of luminescence is that of cold luminescence, not by heating or discharging light, so the component life is about 50~100 times longer than that of tungsten filament bulb, and about one hundred thousand hours.
