Heat tape offers 0.8W/mK

Bond-Ply 800 from Bergquist takes thermal conductivity to 0.8W/mK, and cures at room temperature. The double-sided tape is intended for attaching heat spreaders or heatsinks to assemblies like LED light engines, motor controllers, power converters, or high-performance processors. It has a fibreglass carrier and acrylic…

Just when you thought there was nothing new in optics

Ledil has shortened a collimator for CoBs by some cunning Fresnel-like compression. Called Winnie and for CoBs up to 21mm source diameter, it is only 19mm thick for beams from +/-8° to +/-14°, depending on source size. Even with the unusual light intake, not much has been lost in…
