LED (Light Emitting Diode) is an electronic device that converts electrical energy into light energy. Due to its small size and wide application, LED has been widely used in various modern electronic products. It is the core component of all kinds of electronic displays. Different applications of LED require different working principles.

In general, the most basic working principle of LED is to use the flow of electrons to light up the "doped" semiconductor material. When the electrical current passes through the semiconductor material, the electrons lose energy in the form of photons, and the photons output from the light-emitting layer have different wavelength and color according to the different materials of the light-emitting layer. The range of color and brightness of the LED can also be changed by changing the intensity of the electric current passing through it.

LED Indication - Discrete

LG Indication - Discrete refers to the LED display to achieve information output or other personalized effects by controlling the on or off state of the LED. It is widely used in various electronic devices and mechanical equipment, indicating the operation states, prompting the user tips, and other purposes.

It is mainly used in three main application fields:

1. Industrial field

In the industrial field, the use of discrete LED indicator is also very common. For example, it can be used to indicate the working status of mechanical equipment such as temperature, humidity, and pressure. By sensing the temperature in the operating environment, you can determine the operating temperature of the machine and adjust or turn off the equipment in time.

2. Advertising field

In the field of advertising, discrete LED indicators can also be used to show various patterns and animations. The combination of LEDs of different colors and the frequency of flicker can form numerous different patterns, logos and animations. For example, stores often use LED indicators to display promotional information, promotional slogan, etc., to attract customers\' attention.

3. Automotive field

In the automotive field, discrete LED indicators can be used to indicate the performance of the engine and alert when there is an emergency. Different colors of LED indicators can be used to indicate different functions, such as short circuit or overvoltage. When an exception occurs, the light will give off a corresponding indication, in order to remind drivers of a possible fault.

The working principle of discrete LED indicator is relatively simple. When the controller receives the signal from the sensor, it controls the LED indicator to light up or turn off. It does not have to control the brightness of the LED, so the driving circuit for discrete LED indicator is also relatively simple.

In conclusion, with the advancement of modern electronics, the use of discrete LED indicators has become more and more popular. Due to its simple working principle and wide application, discrete LED indicator has been widely used in various industries. And the development prospect of LED indication - Discrete is very broad.
