When Thomas Edison invented the light bulb in 1879 he turned darkness into light. Half a century later Russian researcher Oleg Losev found a way to turn light into magic when he created the first light emitting diode or LED. This technology has come a long way since then and battery powered LED lights will increasingly light our way as we journey into the future.
Edison’s technology ruled for many years but it is being phased out in many places. The truth is that the LED is simply better and more cost effective than the light bulb. It lasts a lot longer and does not get hot. Gone are the days when this technology was only used to light up the numbers on your radio clock. It is here to stay and has become the shining star in the world of light.
When you combine the versatility of the LED with the power of the battery the sky is the limit. These days LED chips are highly efficient and can provide enough illumination to light up any outdoor trouble spot for added security. Whenever there is a need to illuminate an area outdoors LEDs are present. The diode has become a fully fledged light source and will continue to be that well into the future.
Light emitting diodes have already started taking over in car lights and flashlights. Wherever we go in times to come the LED will go with us to guide us through the dark.
It is now also possible to transform landscapes into enchanted fairy tale worlds with LEDs shaped as illuminated works of art. Outdoor areas can come to life when the sun sets with hundreds of shining fairies, stars or raindrops thanks to the power of battery powered LED lights. These lights can also be used to make walkways safer.
They have proved to be invaluable in the medical world as well. Sometimes a surgeon may need extra light to see into a shadowy area during a procedure. A traditional light bulb comes with heat which may burn the patient. A light emitting diode is cold to the touch. It can even be built into a pen.
In indoor areas these lights are cropping up in unexpected places. They are making their way into closets and pantries. It is no longer necessary to scratch around in the dark to find the right shirt hiding in the shadows at the back of your closet.
The future of light has arrived. Battery powered LED lights will shape our night skies in the years to come. It has brought a new convenience and beauty to our world. It is not difficult to see why this technology is being increasingly embraced in so many fields.
