Design Considerations for Direct Mountable Chip LEDs (NxSxExxA) for High-Density Applications

As a result of growing trends to reduce the size and increase the light energy of LED-based luminaries, the demand for compact, high luminous flux and high efficiency LEDs has been increasing. Since Nichia’s NxSxExxA LEDs are smaller in size than other LEDs that produce the same amount of light energy, they are more suitable for high-density applications that require high brightness and high luminous flux. This document provides information on how the optical characteristics of the luminaire are affected when NxSxExxA LEDs are being used in a high-density application and what issues arise when heat is concentrated on the areas between the LEDs, as well as Nichia’s evaluation results on these issues
