When LEDs are used for a lighting fixture, in general, multiple LEDs, not a single one, are installed in the unit. Operating a single LED generates high heat; all the more heat is generated when multiple LEDs are mounted on a board due to the mutual effect. Then, the junction temperature (hereinafter referred to as TJ) of each LED gets higher, than in a single usage, leading to the decrease in their lifetimes and their luminous flux. Minimizing TJ equates to better thermal management, allowing for a longer lifetime. Therefore, LEDs must be mounted with the optimal pitch among them. This document shows the optimal pitch between LEDs by demonstrating some configurations.
