The LED emits light in brilliant colors with excellent contrast

We define the LEDs efficacy (at maintained lumen per watt) of NeoPac Light Engines at 71.4 lm/W (maintained) for White and 50 lm/W (maintained) for Warm in 2009 and this results the said maintained-lumen output at the said power of the three standard NeoPac Light Engines.We further define the efficacy of NeoPac Light Engines at 100 lm/W (maintained) for White and 70 lm/W (maintained) for Warm in 2010 and it will result the same form factor to deliver same lumen output as in 2009 by keeping the same driving current at 530mA. But the power of the three NeoPac Light Engines will be automatically reduced from 14W (1000 lm/700 lm) to 10W (1000 lm/700 lm), from 10W (700 lm/500 lm) to 7 W (700 lm/500 lm) and from 7W (500 lm/350 lm) to 5 W (500 lm/350 lm) since the 8 chips NeoPac Emitter will be replaced by 6 chips NeoPac Emitter for the 14 W-based NeoPac Thermal Module, the 6 chips NeoPac Emitter will be replaced by 4 chips NeoPac Emitter for the 10 W-based NeoPac Thermal Module, the 4 chips NeoPac Emitter will be replaced by a new developed single big chip (70 mil) NeoPac Emitter for the 7 W-based NeoPac Thermal Module respectively.

The tiny dimensions of these components enable a very large number of pixels to be accommodated in a small display area. The LED is housed in a black package that reflects hardly any ambient light at all. The LED emits light in brilliant colors with excellent contrast.With this LED it is possible to have a pixel spacing of only 2 mm so that a great many pixels can be provided in a small area.For example, an area of less than 10 m2 is sufficient to display pictures in HDTV quality and accommodate more than 2 million pixels. A 2.5 x 4.0 m display achieves a system luminance of 1500-2500 cd/m2.This corresponds to around ten times the luminance of a conventional LCD TFT screen.Perfect color mixing takes place in the package itself thanks to the specially developed encapsulation material. Color appearance remains constant across the entire viewing angle, and the picture appears vibrant even when viewed from the side. Ambient light cannot ruin the picture quality because it is barely reflected at all by the black package in which the LED is housed.

The new LED is optimized for general lighting, consumer, and general applications with a high luminous flux requirement and as an alternative to incandescent lamps. Typical end products will include street lighting, architectural lighting, general illumination, and automotive applications such as daytime running lights, interior lighting, fog lights, and door ajar warning lights.The 2009 Lighting for Tomorrow (LFT) competition is to take place May 14-15. OnSpeX, a division of CSA Group and a global provider of consumer product performance evaluations, inspections and advisory services is hosting the judging event for the competition at its testing facility in Cleveland, Ohio, the U.S.
