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. A luminaire using this technology would represent the current state-of-the-art task light. In addition, the technological improvements in thermal management and LED device performance demonstrated in this project will have application to virtually all future LED luminaires.
Approach
The approach taken in this project will be 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.
