LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

The ELM21003YD is an example of an LED. This type of LED is used in applications such as circuit board indicators, arrays, light bars, bar graphs, and many others. The main advantage of using this type of LED is that it is energy efficient, durable, and reliable. It also has a wide operating temperature range, excellent shield performance, and is available in a variety of different packages and colors.

Application Fields

The ELM21003YD is mainly used in systems that require a visible indicator to signify an event or action. This could be a circuit board indicator in a product such as a computer motherboard, an array which is used to show the status of a machine, or a light bar which is used to alert users of an emergency. In addition, these LEDs can be used in bar graphs that show the level of a particular measurement such as temperature or pressure. This type of LED is also popular in applications such as reverse engineering or product prototyping.

Working Principle

The working principle of the ELM21003YD involves the use of two important components to produce light. These two components are the semiconductor substrate and the light emitting diode (LED). The semiconductor substrate acts as a support structure for the LED, allowing electrons to travel between the two components. This process is known as electroluminescence, which is the result of electrons being excited when energy is applied to the LED.

Once the energy is applied, electrons then travel through the semiconductor substrate and activate the LED, producing a visible light. This process occurs very quickly, within nanoseconds, resulting in a very short pulse of light. The intensity of the light produced depends on the amount of energy applied to the LED and the distance between the LED and the semiconductor substrate.

Summary

The ELM21003YD is an example of an LED that is used in many applications that require a visible indicator. It is efficient, durable, and reliable and is available in a variety of packages and colors. Its working principle involves the use of electron travel from a semiconductor substrate to a LED, producing a visible light at a very short pulse. This LED is popularly used in circuit board indicators, arrays, light bars, bar graphs, and many other applications.
