LEDs, or Light Emitting Diodes, are everywhere—from the blinker in your smartphone to the streets lit up at night. Let’s dive deep into the world of LEDs to understand what makes them glow so efficiently and the myriad ways they illuminate our world.
What Are LEDs?
LEDs are semiconductor devices that emit light when an electric current flows through them. Unlike traditional incandescent bulbs, LEDs don’t have a filament that will burn out, making them more sustainable and long-lasting.
The History of LEDs
LED technology dates back to the early 20th century, but it wasn’t until the 1960s that the first practical LED was developed. This breakthrough led to the widespread use of LEDs we see today.
How LEDs Work
At their core, LEDs work by allowing electrons to combine with electron holes within the device, releasing energy in the form of photons—this process is called electroluminescence.
The Benefits of LED Lighting
The advantages of LEDs over traditional lighting are numerous, including higher efficiency, longer lifespan, more durable, and environmentally friendly.
Types of LEDs
There are several types of LEDs, including miniature, high-power, and OLEDs (Organic LEDs), each serving different purposes across a range of applications.
The Color Science of LEDs
LEDs can produce a wide spectrum of colors, controlled by the materials and mechanisms within the semiconductor. This makes them ideal for various displays and lighting needs.
Applications of LEDs
