What is SMD?
“SMD” er en forkortelse for “Surface-Mount Device”.  Det er en type LED, hvor komponenterne er fastgjort direkte til overfladen af et printkort. I sammenligning med “COB” kræver høj lumen (lm) output mere plads til dioderne. Sammenligning: Task Lamp TL5000 bruger 120 x SMD til en output på 5000 lm, mens Task Lamp X4 kun bruger 1 x COB til en output på 3800 lm. SMD’er udsender dog mindre varme, så de kan installeres i plastikkabinetter i stedet for aluminium eller metal. Denne teknologi kaldes ofte anden generations LED.
“SMD” is an abbreviation for “Surface-Mount Device”. It is a type of “LED” where the components are attached directly to the surface of a “printed circuit board”. In comparison to “COB”, high lumen (lm) output requires more room for the diodes. Comparison: Task Lamp TL5000 uses 120 x SMD for an output of 5000 lm, while Task Lamp X4 uses just 1 x COB for an output of 3800 lm. SMDs emit less heat, however, so they can be installed in plastic enclosures rather than aluminum or metal. This technology is often called second-generation LED.
