Did anyone see the Solid State Lighting invention on the ABC New
Inventors program last Wednesday?
... or watch the video:
Does the following description sound like anything out of the
ordinary? Surely the idea of using the LEDs themselves to rectify
current is nothing new. In fact I suspect that's how my LED night
light works, ie by using strings of antiparallel diode pairs.
As for the claim that "his LED lights have an ingenious way of
directing the electric current", what does he mean by that?
I seem to recall that he said that his innovation involved
"architectural" changes (redesigned lenses?), and that the LED current
was 415mA. Presumably he is using off-the-shelf LEDs.
Here is an excerpt from the Overview:
"There are some LEDs being used for bulk lighting applications, but
these require rectifiers (to transform the current from AC to DC) as
well as heat sinks and cooling fans to run ? not Keith?s lights.
So far, engineers have been scratching their heads as to how the
lights achieve the massive power saving and low heat losses. Keith
will only say that his LED lights have an ingenious way of directing
the electric current ? the rest is a secret! (aka snake oil ???)
Keith has also developed an innovative way to change the current from
the mains AC into the DC needed to run an LED. The diode itself is
used to ?rectify? the current. By doing this, Keith?s lights save more
power and run much cooler than current lights."
