(6) environmental pollution: no harmful metal mercury.
(7) Color: change the current can change color, light-emitting diodes by chemical modification methods, adjust the material& acute;s band structure and band gap, to achieve multi-color light orange red Huanglv Lan. As for the red LED, as the current increases, it can turn to orange, yellow small current, and finally to green.
(8) Price: LED& acute;s are expensive, compared to incandescent lamps, LED prices few can be comparable to the price of an incandescent lamp, but usually each signal to be 300 to 500 diodes.
3.3 LED& acute;s electrical characteristics
Unipolar LED is a PN junction diode formed by a semiconductor inorganic material, which is a semiconductor PN junction in a diode, the voltage - current relationship between the called volt-ampere characteristics. Figure 3.2 shows, LED electrical parameters include the forward current, forward voltage, reverse current and reverse voltage, LED must to work properly at the right current and voltage driven. LED& acute;s can be obtained by testing the electrical characteristics of the maximum allowable LED forward voltage, forward current and reverse voltage, current, and in addition, the LED can be determined optimum operating electric power.
