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

1. INTRODUCTION
An electrodeless lamp is a light source in which the power required to generate light is transferred from the outside of the lamp envelope by means of (electro)magnetic fields, in contrast with a typical electrical lamp that uses electrical connections through the lamp envelope to transfer power. There are three advantages of eliminating electrodes:
Extended lamp life, because the electrodes are usually the limiting factor in lamp life.
The ability to use high efficiency light-generating substan ....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
