The goal is not just to place LEDs on a board, but to ensure that heat generated by each LED can be transferred efficiently to the copper core and then dissipated uniformly across the entire lamp structure. If thermal design is weak, the result is immediate: brightness inconsistency, color drift, and reduced reliability.<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Thermal design must start from junction temperature control<\/mark><\/strong><\/p>\n\n\n\n<p>The most practical way to begin is to define the allowable LED junction temperature, because this directly determines light stability in surgical environments.<\/p>\n\n\n\n<p>A simplified engineering model is:<\/p>\n\n\n\n<p><strong>Tj = Ta + P \u00d7 R\u03b8(total)<\/strong><\/p>\n\n\n\n<p>Where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Tj<\/strong> = LED junction temperature<\/li>\n\n\n\n<li><strong>Ta<\/strong> = ambient temperature inside the lamp head<\/li>\n\n\n\n<li><strong>P<\/strong> = power per LED<\/li>\n\n\n\n<li><strong>R\u03b8(total)<\/strong> = total thermal resistance from junction to ambient<\/li>\n<\/ul>\n\n\n\n<p>This formula is not theoretical\u2014it directly tells you whether your PCB structure is acceptable.
