This LED emits hyper red light with a dominant wavelength of approximately 645nm, making it suitable for applications requiring red light sources. The LED is encapsulated in colorless diffused resin, which contributes to its wide viewing angle of 160 degrees, ensuring visibility from different directions.
This component is characterized by a forward voltage range of 1.8V to 2.6V at a standard test current of 20mA. It has been designed with chip technology based on Gallium Arsenide Phosphide (GaAsP), known for its efficiency in red light emission. The LH R974-LP-1 is also equipped with ESD protection, capable of withstanding up to 2kV according to ANSI/ESDA/JEDEC JS-001 (HBM), enhancing its robustness in various operating environments.
LEDs
LEDs (Light Emitting Diodes) are semiconductor devices that emit light when an electric current passes through them. They are widely used in various applications due to their efficiency, long life, and compact size. LEDs come in different colors, sizes, and brightness levels, making them versatile for a range of lighting and signaling applications.
When selecting an LED for a specific application, it's important to consider factors such as color, intensity, viewing angle, and power requirements. The color of the LED is determined by the material composition of the semiconductor, while the intensity and viewing angle are influenced by the design of the LED package and lens. Power requirements, including forward voltage and current, are critical for ensuring the LED operates efficiently without being damaged.
LEDs are used in a wide range of applications, from simple indicator lights to complex display and lighting systems. They are preferred in many applications for their energy efficiency, low heat output, and long lifespan. In addition to these benefits, LEDs offer fast switching times and are resistant to shock and vibration, making them suitable for use in harsh environments.
When integrating LEDs into a design, engineers must also consider thermal management, as LEDs can generate significant heat at high power levels. Proper heat sinking and thermal management techniques are essential to maintain the performance and reliability of LED components over their intended lifespan.
