LED Indication - Discrete is a type of electronic lighting that has numerous applications in various industries. The application field and working principle of SML-D12U1WT86 are no different from other LEDs and can be used in many applications. This article will take a look at the application field and the working principle of the SML-D12U1WT86.

Application Field of SML-D12U1WT86

The SML-D12U1WT86 is an LED used primarily for indicator lights. It is an extremely low-cost, long-lasting light that is quite reliable and easy to install. The LED produces minimal heat, making it an ideal choice for lighting up signs or discretely providing an indication that something is happening. The low-energy consumption of the LED makes it an excellent choice in many energy-conscious applications such as residential power-saving measures.

In addition to indicator lights, the SML-D12U1WT86 can also be used for single-color display backlighting, such as for digital timepieces, as well as for backlighting numeric displays. It can also be used for products such as handheld electronics, GPS systems, barcode scanners, and consumer products. The LED is also used commonly as an industrial indicator lamp, signaling the status of equipment, switches, or valves.

Working Principle of SML-D12U1WT86

LEDs in general are semiconductors that produce light when electric current passes through them. Inside the SML-D12U1WT86 is a semiconductor material called a die, which contains a layer of n-type materials and a layer of p-type materials. On top of the die are two electrodes, the anode and the cathode, which serve as the positive and negative terminals of the LED.

When current is passed through the LED, electrons in the n-type material start to move towards the anode, while holes in the p-type material start to move towards the cathode. As the electrons and holes combine, they release energy in the form of photons which is perceived as light. The brightness of the LED is determined by the intensity of the current that passes through it, which is in turn determined by the voltage applied to the LED.

In the SML-D12U1WT86, there is a built-in current limiting resistor, which limits the current that passes through the LED and thus controls the intensity of the emitted light. This allows the user to switch the LED on and off easily, as well as control the intensity of the light emitted.

Conclusion

The application field and working principle of the SML-D12U1WT86 LED are much like other LED types, but the low-cost, low-energy aspect and long lifetime makes it a preferred choice for many applications. It’s an excellent choice for residential power-saving measures, indicator lights, backlighting applications, as well as for industrial signaling. The current limiting resistor makes it easy to switch the LED on and off, making it a great choice for any lighting application.
