Patch LED light does not flash, why?
Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
Hit the meter on the buzzer and measure the patch individually. If the flash is a patch, the light goes off.
Are you saying that lamp is flashing? You can check the power output, according to your standard parameters and SMD beads, lamp panel series parallel mode, calculate the power output to output power of the test, you may be wrong, power, overload, but also the effective part of you may be the circuit for power transmission is not stable or low
There are three main reasons:1, the temperature is too high, resulting in LED lights, dead lights.2, do not do anti-static measures, electrostatic breakdown chip, resulting in damage to the LED light.3, the use of LED lamp quality is too bad, the purchase price reasonable LED lights
