LEDs or Light Emitting diodes have been around since the 1960’s as ‘practical’ electronic components. There have been huge advances in their efficiency and light output in the last several years. They come in many colors today and I’m sure there will be more in the future.
The use of LED’s as light sources has now become mainstream to the point that some of us are now using LED lights in our homes to replace incandescent light bulbs and even replacing CFLs (Compact Fluorescent Lamps) in some applications. Some of you will remember the Flick Watch of the seventies. The originator was the Pulsar. Back in 1972 few consumer gadgets were as cool and sought after if you could afford one, as the led watch. The Pulsar watch’s debut on the Johnny Carson show in 1972 kicked off the craze – the Pulsar P1 is generally accepted as the first electronic digital watch. Battery life with these watches was terrible. The face of the watch remained dark until you flicked it to turn on the LEDs and see the time in red. These watches from a practical viewpoint were only useful indoors as the LEDs were simply not bright enough to be seen in sunlight. Some folks are selling some of these “retro” watches today as collector’s items. One website is www.retroleds.com and there are others. Today LED’s come in several colors, some of which are used in phototherapy products. As this website develops we’ll be adding products with Blue, Red and perhaps Yellow LEDs in addition to the bright white LEDs used in the Amjo Sun BRIGHT.
Amjo Sun “BRIGHT” Internal Structure
|Shown here are 25 of the 108 LEDs in theAmjo Sun “BRIGHT”. This structure is uniform and machine made making our lights unique.||This is a single LED. Notice how it is focused towards the front. All of the light generated by the LED is aimed at you!|
This is a photo of the older technology used in some of the lights made by our competitors. It’s easy to see that their assemblies are not as uniform and subject to vibrational challenges and other issues. There can be minor differences between each of the LEDs presenting variations across the face of the unit and if the maker uses a semi-opaque diffuser the light from these older LEDs never gets out of the box.
The Amjo Sun products from ‘the company with the sunny disposition‘ continue to lead the way.
