FPGA based LED illumination Control System

The resource utilization can be improved by the dynamic reconfiguration technique based on FPGA. The methods and prociples for dynamic reconfiguration is discussed in this article. Here, Xilinx Virtex- FPGA and SMCS Ethernet PHY (Physical Layer Transceiver) is utilised to implement a remote dynamic reconfiguration scheme. The RFDRS (Remote FPGA Dynamic Reconfiguration System) can remotely control the changes freely in the eight LED (Light emitting diodes) lighting modes. This method can be v ....etc

Palm-vein detection is a biometric system which has mainly been devel-
oped in Japan and is already in commercial use, e.g. in nance and health
care. The pattern of veins in a human palm is a randotypical feature that
emerges during tissue growth and is therefore likely to be distinct even for
identical twins. At the same time, it o ers a relatively large feature vector,
resulting in attractive error rates being possible.
In this proposed project, a palm vein pattern sensor is to be developed,
which will require a combination of physica ....etc

White LED (Light Emitting Diode) is expected to be the next generation of lamps due to its properties such as high brightness, reliability, low consumption and long life span. In this article , the proposed system for indoor optical wireless duplex channel communication system, as an access to the Internet, utilizing both white LED lights and infrared LEDs is described. The illuminance and power distribution, impulse response, and modulation techniques has been studied in this article. LED lights and receivers design strategies has also been d ....etc

Abstract
Until recently, however, the price of an LED lighting system was too high for most residential use. With rising sales and falling prices, it has been said that whoever makes the best white LED will open a gold mine.

White LED lighting has been used for years by the RV and boating crowd, running off direct current (DC) battery systems. It was then popularized in out-of-network homes, powered by photovoltaic cells. It used to be that white LED was only possible by rainbow groups of three LEDs - red, green and blue - and cont ....etc

I feel as though there are many individuals on this site who haven't had the opportunity to see what our customers are doing with our products . I know browsing through thread after thread to see results can be daunting, so I've gone ahead and collected photos from many various grow demonstrations that are either completed, near completion, or in progress to show you that the future of lighting technology is here!

There are two ways of producing high intensity white-light LED. One is to first produce individual LEDs that emit three primary colors ? red, green, and blue, and then mix all the colors to produce white light. Hence the product is called multi-colored white LEDs (sometimes referred to as RGB LEDs). Because its mechanism is involved with sophisticated electro-optical design to control the blend and diffusion of different colors, this approach has rarely been used to mass produce white LEDs in the industry. Nevertheless this method is particular ....etc
