Full service verbal design agency Zenmark recently assisted SWITCH Lighting with the development of a name for their new LED cooling technology. Newly-named LQD Cooling System, SWITCH Lighting’s patented LED cooling technology utilizes a coolant made of liquid silicone and a highly efficient piston that deals with internal pressure. The two components work in sync to cool the … [Read more...]
Detailed System Level Modeling of LEDs
Introduction Developments in solid state lighting (SSL) in recent years have led to an extensive increase in the driving current of light emitting diodes (LEDs). Although corresponding increases in light output and efficiency has also been noted, current lighting design applications require the implementation of multiple diodes to allow its utilization in universal lighting … [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...]
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...]
