Although
artificial lighting consumes 20 percent of
U.S.
energy production, it has low efficiencies – from 10 percent for incandescent
lamps to 30 percent efficient (high cost) lamps.
This project will develop a unique process to produce high efficiency,
porous ceramic, incandescent light bulb filaments with tailorable spectral
emission characteristics. The
process will be based on a previously-developed, proprietary technique for
producing porous boride and nitride materials with high thermal shock and
tailorable emission performance. Phase
I will use the proprietary technique to produce robust, selective emitter
components for lamp applications. Efficacy will be proven by building working
demonstration lamps with 400-700 nm spectral emission, low-power/high-output
heating elements, and suitable electrical connections.
The lamps will be characterized for lumens/watt, power consumption, wall
temperature, and life expectancy. Phase
II will optimize materials and processes and demonstrate repeatability in high
lamp performance and cost effectiveness.
Commercial
Applications and Other Benefits as described by awardee:
Commercial applications for this technology should exist in efficient
lighting products for industrial/residential applications and igniters for
gas/oil fired industrial/residential furnaces and appliances.
