    Announcement: Release embargo until 15 November 2003.

    Light Emitting Diode (LED) Intensification Breakthrough in New Zealand
    laboratory.

    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
    then 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.

  2. Sounds like advertising hype to me. What is needed is a more
    efficient LED, not a brighter LED. It sounds to me as if all they did
    was make the LED brighter, without an increase in efficiency.

    Wow a heatsink, how origainal is that a patentable
    idea, maybe, for an LED. Someone had to come up
    with putting a resistor inside a case with fins.

    Sounds like advertising hype to me. What is needed is a more
    I suspect there's too much prior art to allow this. Surely, by now,
    someone has come up with an ultrabright-red-LED tailbulb replacement
    for a '59 Cadillac?

    Hi Dave,
    Thats no way to keep a 59 in original condition.
    Now a 99 maybe... if the computer is not watching
    the current draw for any difference.

    I don't think a '99 has fins? That seemed to be a requirement, and
    the '59 was quite notorious in that respect.

    Zoom, right by me, I missed the point.
    And a good one.

    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

  10. You seem a bit confused, can you tell us if you think LEDs are
    voltage-mode or current mode devices?
