High-Power LED Market Estimates (US$MM)
−
Flat Panel HD-TVs can use 5000 LEDs per TV, which is a prime
target for a PFC-IC for use with discrete LEDs.
−
General Illumination applications would benefit from a full custom
PFC-SSL IC, with PFC and LEDs integrated on a single chip.
Technology Trends
→ Incandescent
→ Fluorescent
→ Compact Fluorescent
→ Solid State Lighting (“SSL”) LEDs
→ PFC-SSL estimated over $100MM by 2011

LEDeep Technology Overview

Power-Factor-Corrected Solid-State Lighting
−
Directly power LEDs from the grid.
z
z
z
z
Eliminates the AC to DC power conversion
Electric utilities charge more for non-unity power factors,
and the PFC is a near unity PF usage
Power supply monitoring allows PFC to assist the whole
circuit to have improved PF.
Helps fix poor PF from other devices on the same utility
circuit, including Compact Fluorescent lamps, motors,
compressors.

Power-Factor-Corrected Solid-State Lighting (“PFC-SSL”)
PFC correction circuit turns
on the number of LEDs
that draws a near-linear
current as the AC voltage
varies from 0 volts to
115/230 Volts.
Pseudo-resistive load
Adding intelligent controls
allows for this topology to
absorb the noise from
other energy consumers to
help the overall circuit have
a unity power-factor.

A divisional patent application can be filed with claims related
to PFC-SSL, and additional patent applications can be filed.
Original US Pat App. 2007/0276455 as a base for divisional
patent application claiming PFC-SSL:
−
“... A final aspect of the invention provides various
circuits that may be used to power the LEDs used in
the present systems and devices. ... FIG. 15 shows a
direct line voltage power supply that has a useful
near unity power factor LED transfer function which
is useful to remove the need for a switching power
supply utilizing resistor ladder network to creates
bias for transistors. ...”
