    LTST-C190GKT device package

    LTST-C190GKT schematic symbol

    The invention of LED (light emitting diode) is considered as one of the biggest milestones in semiconductor and electronics technology. Before LEDs, the incandescent light bulbs and halogens lamps were the only electric powered light sources available. The use of photoelectric phenomena in the semiconductors brought forth a great revolution. Today LEDs are used in all types of electronic circuits and scientific applications. Devices like IR remote controllers, seven segment displays, automotive headlights, camera flashers, and medical lights owe their existence to LED technology. Today LEDs are available in all type of shapes, colors and sizes to fit a large array of applications.
