One, the characteristics of different
Light-emitting diodes compared to ordinary diodes have a small size, colorful, low power consumption, high luminous efficiency, fast response time, vibration and long service life and other advantages.
Two, different uses
1, light-emitting diodes: light-emitting diodes in modern society has a wide range of uses, such as lighting, flat panel display, medical devices.
2, ordinary diodes: mainly used in household appliances, industrial control circuits.
Three, the role of different characteristics
1, light-emitting diodes: through the electron and hole complex release energy to emit light, it is widely used in the field of lighting, light-emitting diodes can be efficiently converted into light energy.
2, ordinary diodes: the use of diodes and resistors, capacitors, inductors and other components for a reasonable connection, constituting a different function of the circuit, can be realized on the alternating current rectifier, on the modulated signal detection, limiting and clamping, as well as on the power supply voltage regulator and so on a variety of functions.
