the LED lamp bead as semiconductor light-emitting diodes (leds), it USES the semiconductor materials. Can directly into the electric energy into light energy; It has low consumption, high brightness, colourful, anti-vibration effect is good, long service life, low exothermicity, is a green lighting.
as the semiconductor light-emitting diode devices for LED lamp bead, belongs to electronics, so it is more sensitive to electrostatic, in addition will also because of the reason of electrostatic, caused it to appear a series of problems. So in the packaging, need to be failure voltage test.
by the small make up to say, you know whether for the LED diode more deeply.
