LED
LEDs (Light Emitting Diodes) are semiconductor devices that emit light when an electric current passes through them. They are widely used in a range of applications, from simple indicator lights to complex display and lighting systems. LEDs offer advantages such as high efficiency, long life, low power consumption, and compact size.
When selecting an LED, important parameters to consider include color, wavelength, brightness (luminous intensity), forward voltage, and current. The choice of color and wavelength depends on the application's requirements. Brightness is crucial for visibility in various lighting conditions. Forward voltage and current specifications ensure compatibility with the rest of the circuit.
LEDs are used in a multitude of applications, including consumer electronics, automotive lighting, outdoor signage, and medical devices. Their small size and efficiency make them suitable for portable and battery-powered devices. Additionally, the ability to control the brightness and color of LEDs has led to innovative uses in decorative and ambient lighting.
Proper handling and mounting of LEDs are important to maintain their performance and longevity. This includes considerations for thermal management, current regulation, and protection against electrostatic discharge (ESD). Designers must also take into account the LED's viewing angle and intensity distribution to achieve the desired lighting effect.
