Taiyuan Teng Yuan ad with you to resolve punching word lamp beads emitting principle: the principle of piercing the word lamp beads is illuminated, the voltage across the PN junction to a certain barrier, plus the forward bias voltage of the times when the barrier fell, P Most carriers region and N region to the other diffusion. Since the electron mobility is much greater energy than the hole mobility, so there will be a large number of electrons into the P diffusion region, P region constitute the minority carrier injection, hole recombination of these electrons and valence band to obtain the composite of in the form of energy release out, to form a perforation word lamp beads light. My company has first-class equipment, price concessions, welcomed the choice of us! Punching the word can be called "piercing the word" luminous characters Shanxi pictures, also called "Punch word."
