Because of its good light efficiency, good stability, environmentally friendly and energy -saving because of its good light efficiency, good stability, and good energy saving.Patch emitting diode is used in ordinary lighting and commercial lighting, but it is more for street lights and large parking lots or indoor direction lighting.This is because the service life of the glowing diodes in the actual application is much higher than that of ordinary light bulbs, and the required energy consumption is lower.

Patching light -emitting diode positive and negative poles
Observation method of the method of positive and negative pole judgment of the glowing diodes: The positive and negative judgment of the patch luminous diode can be judged from the two leading lines on the side of its side.The negative electrode is large.Secondly, the pins of the glowing diodes of the patch are short. Usually, the long pins are the positive electrode, and the short pins are the negative electrode.Masterpiece detection method of positive and negative pole judgment methods of patch glowing diodes: When the multi -meter -of -meter -of -glow diode positive and negative poles are detected through a multimeter, be sure to use the gear of "R*10K" to detect it.During the test, the two tablets are connected to the two leads of the emitting diodes.If the surface of the table is turned over half, there is a light point in the glowing diodes, indicating that the patch glowing diodes are positive.At this time, the positive pole is connected to the black watch pens, and the red table pens are connected to the negative electrode.The two tablets are connected to the light -emitting diode, and (reverse access), the shot is not moving.Regardless of whether it is positive or reverse access, the acupuncture point is not moving or the deflection is over, indicating that the glowing diodes of the patch are damaged.
