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...]
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...]
Flip Chip Micron Scale Thermal Mapping Solution
Microsanj has introduced flip chip micron scale thermal mapping solution, a new high performance product in the Thermoreflectance Nanotherm Series. The NT220A, featured at the IPFA-2012 Conference in Singapore, adds near-infrared capability to support through-the-substrate thermal imaging. This feature enables accurate high resolution thermal mapping and analysis of flip-chip … [Read more...]
New Technique for Making Brighter, Cooler LEDS
A new technique for making brighter and cooler LEDs has taken the first leap from research laboratory to market. The new manufacturing system, called liquid forging, dramatically improves the way tiny electronic devices keep cool with a thermal conductivity double that of conventional techniques such as casting. The liquid-forging method was developed by A*STAR’s Singapore … [Read more...]
