The thermal design of an LED fixture affects its light output, efficiency, cost, lifetime and reliability. LED based fixture designers and managers who are concerned about any of the above lighting fixture parameters are highly recommended to consider the practical simple concepts outlined in the following series of “Thermal Design Considerations” application notes. Thermal management
Written by engineers, for engineers, our application notes are designed to share our brightest ideas with the technical depth and details to help you embed ERP LED drivers into your next lighting fixture design.
Heat transfer can occur in three different modes: conduction, convection and radiation. The purpose of this application note is not to bombard the reader with a ton of equations. However, a fixture designer must be well aware of the controlling parameters in the equations in each heat transfer mode. Understanding and utilizing the key parameters
