Discrete Light Emitting Diodes (LEDs) are single-chip optoelectronic devices that convert electrical energy into light through electroluminescence. This product category forms the foundation of modern indication systems, offering advantages including low power consumption, long lifespan, and high reliability. Their importance spans across consumer electronics, industrial equipment, automotive systems, and communication infrastructure.
| Type | Functional Characteristics | Application Examples |
| Visible LEDs | Emits light in visible spectrum (400-700nm), available in multiple colors | Indicator lamps, display backlighting, decorative lighting |
| Infrared LEDs | Emits 700nm-1mm wavelength radiation, invisible to human eye | Remote controls, security sensors, night vision systems |
| High-Brightness LEDs | Enhanced luminous intensity (>1000mcd) with advanced packaging | Automotive lighting, outdoor displays, emergency signage |
| UV LEDs | Ultraviolet spectrum emission (280-400nm) | Sterilization equipment, counterfeit detection, curing systems |
Typical discrete LED construction includes:
| Parameter | Significance | Typical Range |
| Wavelength | Determines light color and application suitability | 375nm-940nm |
| Luminous Intensity | Measures brightness output (mcd) | 50-10,000mcd |
| Forward Current | Operating current rating | 20-150mA |
| Forward Voltage | Electrical potential drop | 1.8-3.6V |
| Viewing Angle | Light emission spread measurement | 5 -120 |
Primary application sectors include:
| Manufacturer | Product Series | Key Features |
| Cree Inc. | XLamp XP-G3 | High brightness (3200mcd), 120 viewing angle |
| OSRAM Opto | OSTAR Projection | High-power LED for automotive lighting |
| Nichia Corp. | NSHU5991 | UV LED (365nm) for curing applications |
| Everlight Electronics | LTST-C19HE8WT | Tri-color LED for RGB indication |
