Cree Study Shows LED Lighting is Best Bet for Energy Efficiency

Comparison of the use phase and production energy consumption for various lighting technologies (Carnegie Mellon LCA). LED lighting at an efficacy of 60 lumens per watt has a comparable overall energy consumption to CFL.2 With higher efficacy LED products, A new report on the life-cycle energy usage of energy-efficient lighting by Cree, Inc. shows that LED lighting products are now more efficient than traditional lighting products when compared across the high-volume applications of recessed downlighting and display spotlighting. Evaluating light fixtures and applications, the white paper’s energy comparisons demonstrate that LEDs offer clear advantages in terms of energy costs and environmental impact over traditional lighting such as incandescent, halogen and compact fluorescent bulbs.

On the Standardization of Thermal Characterization of LEDs

Figure 3: Sketches of some mainstream power LED packages. Unlike two decades ago in the IC world, the junction temperature (Tj) of an LED is not just a performance indicator of the thermal design but also plays a major role in lighting design since many properties of the light output of an LED depend on the absolute junction temperature. This means that thermal management should be an integral part of the system design of an LED based lighting solution, resulting in changing roles of different engineering disciplines in the overall design process - as will be discussed later in more detail.
