In today’s world, you just can’t escape LEDs. You switch on a device, and there’s a good chance that an LED is behind it. LEDs are there in almost everything you use (and don’t use) all around you – in all sorts of gadgets in your home, mobile phone, cars, street lights, offices, auditoriums, industrial lighting, ....you get the picture. They come in all kinds of sizes, shapes, and colors, but no matter your opinion of the LED: they are here for the long haul!
LED stands for “Light Emitting Diode” and they create light by electroluminescence in a semiconductor material. To put it simply, electroluminescence is the phenomenon of a material emitting light when electric current or an electric field is passed through it. Some advantages of LEDs over, say, incandescent lamps are that, though they are much smaller in size than a traditional light bulb, LEDs emit more light per watt and the on/off time is much shorter than other types of electric light sources. What’s more is that their lifespan is drastically longer, and LEDs are quite hardy and resistant to damage from heat and vibrations.
DID YOU KNOW?
For over 30 years, LEDs have been used in various areas and applications. GoodBulb is excited to report that we have kept pace with the advancement in LED technology to stay ahead of the curve and bring the most relevant and efficient lighting products to our customers! Did you know that in recent years, the white LEDs' luminous efficacy has increased to a startling 130 lumens per watt and more? This is a trend that will continue into the future with more breakthroughs in this rapidly evolving industry.
LIGHT BULB MOMENTS
In 1962 Nick Holonyak Jr., employed in General Electric, invented the first light-emitting diode that emitted light in the visible part of the frequency range. It was a red LED. In 1972, M. George Craford, who was a graduate student of Holonyak, invented the first yellow LED and an even brighter red LED, to boot!
