    Light Emitting Diode (LED) Intensification Breakthrough in New Zealand

    Using ultra-small electronic componentry to intensify (make brighter)the
    ubiquitous LED, the LED output can be increased by up to four times without
    blowing them up as would be expected when you shove too much voltage into
    them. The Free Electron laboratory technicians in Lower Hutt, North Island,
    New Zealand have developed a device to intensify LED's by overpowering and
    cooling LED's to make an otherwise mediocre LED shine furiously bright.

    Given the headlong rush to more Lumens per Watt and the wide range of
    applications that LED's lend themselves to, it is surprising that such
    an add-on component has not, before today, been developed. The LED
    Accelerator brings a solution to bear upon the problem of otherwise poor LED
    luminosity performance. At an increasing rate LED's are being used in
    industry, transport, home and personal lighting, security, communications,
    toys and consumer electronics, the future is bright then, for a company
    that will manufacture and distribute the LED Accelerator.

    In the next few days it is expected that rights to the device will be
    auctioned by eBay and at other auction sites in Europe, and Australasia.

    Time to update information for detractors, supporters and other souls kind
    enough to provide feedback herein:

    The circuit does not change the colour of the LED.

    Most LEDs do not operate at 100% duty - brake lights for example, life
    reduction expectancy therefore UP TO 30%.

    The circuit does not directly influence the efficiency of the LED, it just
    allows a higher voltage to be safely applied to the LED.

    In this incantation the circuit is designed for arrays of LED's, such as
    traffic lights, indicators and tail lights. It's use will be more
    applicable, therefore, to interior lighting, automotive, traffic and
    industrial applications.

    The low power version sinks 1 Amp, and the power device <4 Amps - which is a
    huge output so far as LED applications are involved. At the four Amp rating
    8 devices could easily power aircraft runway lights.


    A typo on the website has been fixed.

    Thankyou for suggestions insofar as Lumileds and Luxeon are concerned.

    Do please post on-topic communiques to this NG rather than posting emails as
    is the want in NG culture.

    An announcement will be issued shortly as to auctioning the rights to
    use/manufacture the device.

    Yours faithfully

    Hmmm... Is it an integrated circuit for pulsing leds higher than they
    are rated? A LED flasher with high frequency so the LEDs have a little
    time to cool down between each pulse, but does look like its
    constantly on?

    Hmmm... I was just a little currious about the breakthrough part,
    really... Overdriving LEDs has been done before, some LEDs even have
    maximum current for a pulse of a specific duration, heat dissipation
    and so on in their datasheet ...

    But I don't want to be nosing in to your industrial secrets or
    anything, sorry...

    I'll be interested to see if the announcement is picked up in the
    mainstream -- Science Magazine, EE Times, IEEE publications, and so on.
    It's hard to associate a genuine scientific breakthrough with a Geocities
    web page.
