The newly developed Vitralit® UD 1405 adhesive is an innovative adhesive system for fibre and filament winding. For high efficiency, Vitralit® UD 1405 can be applied during the winding process and immediately cured with high intensity LED curing systems. This adhesive and curing system is ideal for Carbon or Glass Fibre filament winding associated with Carbon Fibre Reinforced … [Read more...]
Thermal Management of Chip-on-Board LED Systems and Their Aging Response to Cyclic Power
By: Lisa Mitterhuber, Julien Magnien, Elke Kraker Introduction Twenty years ago, a lamp had exactly one purpose—to illuminate the room. A typical incandescent lamp lasted a year and failure was caused by a filament or/and a glass breakage [1]. Nowadays typical lighting is based on LED technology, which is considered as durable. Due to the fact that many materials are … [Read more...]
Solder Joint Lifetime of Rapidly Cycled LED Components
Reprinted from the June, 2014 Issue ACTIVE LEDs in a consumer TV product are boosted and dimmed with the video picture content. Boosting and dimming of LEDs is a powerful means to improve visual experience, either through the application of active LEDs in an ambient light feature or through dimming and boosting of the display LEDs in a direct-lit video display. Active … [Read more...]
What…Use Lasers and LEDs for Cooling?
In a recent blog “Some New Cooling Ideas are Needed Here,” I suggested (hoped?) that someone would figure out how to leverage the thermal laws of physics to devise innovative cooling systems which go beyond widely used, conventional techniques of conduction, convection, and radiation. The reason for looking beyond these solutions is that they seem to have reached a limit as to … [Read more...]
Thermal Management of Displays/Signage in Outdoor Enclosures
Introduction/Background The pace of development in the electronics and telecommunication fields has been accelerating in all aspects of the business. For example, electronics/telecommunications equipment has traditionally been housed in large buildings, smaller buildings (sheds) and outdoor cabinets. The introduction of electronics to the outdoor environment has imposed … [Read more...]
