Light Emitting Diodes (LEDs)
- LEDs are tiny light bulbs that fit easily into an electrical circuit.
- They don't have a filament that will burn out like ordinary incandescent bulbs, and they don't get hot.
- They are illuminated by the movement of electrons in a semiconductor material.
- The lifespan of an LED is a lot more than the short life of an incandescent bulb by thousands of hours.
- LEDs are in mobile phones, cars and our homes and they come in a huge variety of sizes, shapes, and colours. Many products that we now wear include LEDs to illuminate including fancy dress/seasonal costumes, sporting equipment and visibility wear.
- LEDs are a particular type of diode that converts electrical energy into light.
LEDs are like tiny lightbulbs. However, LEDs require a lot less power to light up by comparison. They’re also more energy efficient, so they don’t tend to get hot like conventional lightbulbs do.
