USA - Cree ( http:// ) won the top prize in the 2009 Lighting for Tomorrow - Solid State Lighting Competition. The Cree LR6-DR1000 recessed downlight was awarded the coveted Grand Prize at an award ceremony at the American Lighting Association (ALA) Conference this week.

The Cree LRP-38, a PAR38 bulb, and the LR6-HE (high-efficiency) were also recognized with Special Focus Awards for technical innovation and high efficiency, respectively.

The Grand Prize-winning Cree LR6-DR1000 is a high-output six-inch downlight that produces more than 1000 emissions of light output. Targeted for commercial release early next year, the LR6-DR1000 is designed to operate off an input power of less Than 13 Watts, delivering an efficacy in excess of 73 lumens per Watt which makes it the most efficient, specification-grade LED downlight.

The winner of the technical innovation award, the LRP-38 bulb features Cree
Released in May 2009, the LRP-38 is replacing halogen and ceramic metal halide (CMH) lamps in numerous applications including fresh food displays, furniture stores, retail environments and Museums.

This international design competition is organized by the ALA, the US
The Panel of Energy (represented by Pacific Northwest National Laboratory) and the Consortium of Energy Efficiency. A panel of 11 judges from various areas of the lighting industry evaluated the entries based on color appearance, color rendering, efficiency, innovation and other criteria.

Cree is lighting the LED revolution with breakthrough products that redefine energy-efficient illumination, said Gary Trott, vice president of market development, Cree LED Lighting. Over the past three years, every Cree LED Lighting product has won a Lighting for Tomorrow award.

D-sub Connector Contacts

D-sub Connector Contacts
A D-sub connector is a form of connector commonly found in electronic and computer systems. It consists of a D shaped metal band and two or more parallel rows of either pin contacts (male) or socket contacts (female). D-sub connector contacts can vary in size, material, current rating, length and resistance.

The most common type of connector is the crimp contact. These are assembled by inserting a stripped wire end into the cavity at the rear of the contact. The cavity is then crushed using a crimp tool, gripping the contact to the wire.

What are D-sub connector contacts used for?
The D-sub connector contacts carry the signal from the source to the destination across the D–sub connection.

Types of D-sub connector contacts
Most D-sub connectors are supplied with contacts ready in place. Contacts can be replaced if damaged or if the application of the D-sub connector is to be changed from the original design specification.

High-current, high-voltage, or co-axial inserts require larger contacts. The material of the D-sub connector contact can be changed if the robustness or quality of the connection needs to be improved.
