LED Indication - Discrete

Discrete LED Indication is a type of light-emitting diode (LED) that is used in many applications such as automotive lighting, industrial lighting, and street lighting. They are known for their low power consumption and long life span. The following article is about the application field and working principle of the SLA560BC4T3F LED.

Application Field

The SLA560BC4T3F LED is a discrete LED, specifically designed for application in the field of automotive lighting. This LED has the potential to be used in a variety of applications such as signal indication, warning indicators, and lighting for instrument clusters, headlight beams, indicator lights, and dashboards. In addition, the SLA560BC4T3F LED can also be used in industrial lighting such as indoor and outdoor lighting, and street lighting.

Working Principle

The SLA560BC4T3F LED is a forward-biased diode, meaning that current flows from the cathode to the anode. When a voltage (Vin) is applied to the LED, electrons flow from the n-type semiconductor to the p-type semiconductor, and a photon is released as a result of the recombination of electrons and holes. The wavelength of the photon is determined by the material of the LED; the SLA560BC4T3F LED is a red LED, so it emits a red light.

In addition to the forward-biased diode, the SLA560BC4T3F LED also has a resistor (Rin) in parallel to it. This resistor limits the current flow through the LED and prevents it from burning out. The amount of current drawn is dependent on the supply voltage, the forward voltages of the diode, and the resistance of the resistor. The optimum current for the SLA560BC4T3F LED is 30mA. When the forward voltage of the diode is 3V, the resistance of the resistor should be 470Ω.

Conclusion

The SLA560BC4T3F LED is a discrete LED designed for use in automotive lighting and other applications. It has a long life span and low power consumption due to its forward-biased diode and resistor setup. The current flow through the LED is limited by the resistor, allowing for optimum current flow.
