A red LED (Light Emitting Diode) is a semiconductor device that emits light when an electric current passes through it. The color of the light emitted by an LED is determined by the semiconductor material used in its construction, with red LEDs using gallium arsenide phosphide or aluminum gallium arsenide as their active material.
Where To Use Red Led
Red LEDs are commonly used in a variety of applications, including indicator lights on electronic devices, signage and displays, and even as a light source for general illumination purposes due to their long lifespan and low energy consumption.
Key Features Of Red Led
Low power consumption, typically in the range of milliwatts to tens of watts
Long lifespan, often up to 50,000 hours or more under normal operating conditions
High efficiency, converting electrical energy into light with minimal loss
Rugged construction suitable for harsh environments and high reliability
How To Use Red Led
Connect the anode to a positive power source and the cathode to a negative power source
Ensure that the voltage applied is within the recommended range, typically between 1.8V and 2.3V for most red LEDs
Operate the LED at a current level suitable for the desired brightness and lifespan, usually in the range of 10mA to 100mA
Monitor the LED's temperature to prevent overheating, which can lead to premature failure
How Red Led Is Manufactured
The manufacturing process of a red LED involves several key steps:
Technical Specification Of Red Led
Forward Voltage (Vf)
1.8 - 2.3 V
Forward Current (If)
10 - 100 mA
Luminous Intensity (Im)
10 - 100 mcd
Operating Temperature Range (°C)
-40 to +85 °C
Power Dissipation (Pd)
100 - 500 mW
The specifications outlined above provide a general overview of the key characteristics and operating parameters of a typical red LED. However, it is essential to consult the specific datasheet provided by the manufacturer for detailed information on the product's performance and limitations.
Description Of Red Led
A red LED is a compact, low-power electronic component that produces light through the recombination of electrons and holes in a semiconductor material. Its primary function is to convert electrical energy into optical radiation, making it a crucial component in various applications, from indicator lights to illumination systems.
Related Products & Synonyms Of Red Led
Some related products of red LEDs include green and blue LEDs, which are used in similar applications but emit light at different wavelengths. The term "red light emitting diode" is often used as a synonym for the product.
