This book provides an in-depth introduction to the fundamentals and practical aspects of LED lamp design. Covering light generation, efficiency, theoretical limits, efficiency limiting factors, and LED lamp design elements, it explains the principles of large-space and 3D object illumination for developing competitive LED lamps. It presents design and simulation requirements for LED lamps with real examples that demonstrate how to make more energy-efficient and higher-quality lamps. This book also applies lamp output metrics and characterization methods to retail and prototype lamps for comparison.
