How to Design with LEDs: Iterative Approach Yields Fully Optimized Lighting Systems

How to Design with LEDs

While the cost of light emitting diodes (LEDs) is decreasing, they are still relatively expensive and their adoption should be carefully considered before making the switch. Optimization of the optic and other system components can reduce the number of LEDs needed and reduce the overall cost of the LED lighting fixture. Solid state lighting (SSL)…


Challenges of Determining LED Useful Life

LED Useful Life

The transition to light emitting diodes (LEDs) from conventional light sources brings several new challenges to lighting engineers and designers. LEDs are much different than incandescent bulbs, especially in terms of useful life. It’s easy to determine the useful life of an incandescent lamp; if the light goes out, its useful life is over. This…
