5mm Super Bright Clear Red LED

Description 5mm Super Bright Clear Red LED The 5mm Super Bright Clear Red LED is one of the most common and versatile electronic components used in modern circuits. Recognized for its efficiency, reliability, and low cost, this light-emitting diode (LED) has become a standard choice for countless applications ranging from power indicators to decorative displays. Despite its simplicity, the component is based on solid-state semiconductor technology and demonstrates the fascinating principles of electroluminescence. Because of its brightness, durability, and ease of integration into circuits, this LED is a fundamental component in electronics education, prototyping, and commercial product design. Basic Description This LED features a clear 5mm red lens that houses the semiconductor material. The physical size, 5mm in diameter, makes it suitable for breadboard use, panel mounting, and PCB installations. It has a typical forward voltage of 2.0Vand a rated forward current of 20mA, which means that it requires a current-limiting resistor when connected to a power source to prevent damage. The cathode, or negative lead, is identified as the shorter pin, while the longer pin is the anode. This polarity must be observed carefully when wiring the component into a circuit. The LED is commonly used as a status or power indicator, an element in opto-electronic sensors, or simply for visual effects. Because of its affordability and efficiency, the 5mm red LED is considered a staple in electronics kits worldwide. Operating Conditions and Specifications The 5mm Super Bright-Clear-Red-LED is designed to operate within a specific voltage range. Its minimum operating voltage is approximately 3.5V, while the recommended operating voltage lies between 9V and 12V. The maximum operating voltage should never exceed 13V. At an optimal voltage of 9V, the LED can achieve a luminous intensity of up to 80mcd, producing a strong and visible red light. Key specifications include: Forward Voltage: 2.0V typical Rated Forward Current: 20mA Maximum Current: Must not exceed 20mA Wavelength: ~630nm (red color) Luminous Intensity: 8,000mcd (maximum) Viewing Angle: 30° The narrow viewing angle provides a concentrated beam of light, making the LED appear very bright when viewed head-on, which is especially useful in indicator and signaling applications. Working Principle At its core, the LED is a two-lead semiconductor light source. When a suitable voltage is applied across its terminals, electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. This process is called electroluminescence, and it is responsible for the visible glow of the LED. The color of the emitted lightdepends on the energy band gap of the semiconductor material used. In this case, the material is engineered to produce light at a wavelength of around 630 nanometers, corresponding to bright red. Applications Understanding the 5mm Super Bright Clear Red LED The 5mm Super Bright-Clear-Red-LED is widely used in various fields: Power and Status Indicators: Provides clear visual feedback in devices to show whether a circuit or system is operating. Displays and Signage: Used in simple numeric displays, message boards, and back-lighting. Opto-electronic Sensors: Functions as part of emitter-detector pairs in sensors for object detection and distance measurement. Educational Projects: Ideal for teaching basic electronics due to its low cost and ease of use. Decorative Lighting: Adds visual effects to DIY projects, toys, and art installations. Usage Considerations While LEDs are robust, they are also sensitive to current. Exceeding the rated forward current of 20mA can permanently damage the component. For this reason, it is critical to never connect an LED directly to a power supply. A current-limiting resistor should always be used in series to control the flow of current. For example, with a 4.5V power supply, a resistor of at least 50 ohms is needed to limit the current below 20mA. The exact value of the resistor can be calculated using Ohm’s Law, depending on the supply voltage and LED forward voltage. Conclusion The LED may appear to be a small and simple component, but it represents a powerful combination of solid-state physics and practical utility. With its high brightness, compact form, and reliability, it is indispensable in modern electronics. From simple circuit indicators to complex sensor systems, this LED plays a vital role in ensuring functionality and providing visual feedback. Its affordability and versatility make it an essential component for both beginners and professionals in electronics. By understanding its operating principles and proper usage, anyone can successfully integrate the 5mm Super Bright-Clear-Red-LED into a wide range of projects. Dimensional Drawings
