    Kaga Components Co Ltd is exhibiting a power supply apparatus for LEDs that has a lifetime of 100K hours. This was shown in an exhibition in Tokyo which took place on April 15 to 17, 2009. The apparatus which is currently under development was exhibited for the first time. How this was achieved? Well, the electrolytic capacitor was removed from the circuit to achieve this lifetime. At the same time the power supply circuit was also downsized. LEDs are going to be lighting source of the future because of its environmental advantages but unfortunately the lifetime of existing LEDs is as low as 10,000 hours.


    No details have been disclosed because the product is still patent pending. The price ranges from US $ 5 to US $ 6.
