Fuji Polymer Industries Co. has released Sarcon 30HR, a silicone-based thin film that exhibits a 1.7 W/m°K thermal conductivity when placed between a heat source and a nearby heatsink. This thermal interface medium eliminates air gaps between components. The increased surface contact can measurably improve the cooling performance of a heatsink. Sarcon 30HR has a thermal … [Read more...]
Heat Sink Extrusions Meet Space Constraints of LED Light Engines
Ohmite Wakefield Solutions’ 19000 Series of radial-fin heat sink extrusions for LED light engines helps meet space constraints and operating parameters. The heat sink extrusions are black anodized for maximum thermal performance, and their radial-fin design has been optimized for natural convection. OHMITE intends for its product to make matching the right heat sink to the … [Read more...]
CPU Cooler Fan for Maximum Cooling Performance
LEPA introduces its Vortex fan, which uses fluid mechanics to generate a powerful air twirl that concentrates cool air on the hot spots inside a system. At full speed, the Vortex fan achieves a static pressure of 2.18mm-H2O while maintaining a low noise level. That way, it is also an ideal solution for CPU coolers or radiators. LEPA equipped the fan with a PWM speed control, so … [Read more...]
Safety Standards for Higher Level Lighting Products
IEC/TR 62778:2012 provides clarification and guidance for the assessment of blue light hazard of all lighting products that have the main emission in the visible spectrum (380 nm to 780 nm). By optical and spectral calculations, it is shown what the photobiological safety measurements relate about the product and, if this product is intended to be a component in a higher level … [Read more...]
Research Progresses LEDs Made out of Silicon
A recent theoretical study by a University of Waterloo doctoral candidate in nanotechnology engineering suggests that manufacturers may one day make lasers and LEDs out of silicon, a cheaper material with greater thermal conductivity. Silicon is not currently used in LEDs or lasers because of its indirect bandgap, which hinders light emission. The new research suggests, … [Read more...]
