The goal of this project is to accelerate
the use of energy efficient light emitting diode (LED)
technology for general lighting applications by developing
a task lamp utilizing high brightness LEDs in a consumer
acceptable light fixture, and utilizing new materials
that have high thermal conductivity that will enhance
lifetime and performance of the LEDs.
Lawrence
Berkeley National Laboratory
is leading the research and development work for this
project.
The
objectives of this project are to:
- Develop
a thermally conductive substrate onto which LEDs
are mounted that enhances the operation of LEDs at
high power loadings while maintaining highest performance
and reliability of the LED.
- Incorporate
the latest developments in LED, phosphor and micro-optics,
to achieve the highest system performance.
- Design,
prototype and transfer technology to luminaire manufacturers
for the production of a commercial grade LED task
light with efficiency equal to or greater than comparable
incandescent and CFL luminaires.

This
project meets the PIER goal of improving the energy
cost/value of California's Electricity by accelerating
the introduction of a more efficient light source as
a replacement for today's inefficient incandescent and
comparable compact fluorescent task lamps. This
project also develops an enabling technology that will
have a significant impact on LED technology, accelerating
the applicability of this energy efficient technology
to broad range applications in solid state lighting.
