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 particula ....etc

Design and manufacture of “White Metal Thrust Bearing”



Abstract of the project :
White metal bearings transmit the thrust exerted by shafts rotating at high speeds to the foundation of the machine. White metal thrust bearings were invented by Anthony Michell in 1905. Here, pads are used instead of rollers or balls and the bearing housing is flooded with a hydrodynamic fluid under pressures of about 100 bar in order to minimize ....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 ....etc

Black Holes
A black hole is a region of space from which nothing, not even light, can escape. John Michell, using Newton’s ideas of gravity as a force, saw that if a strong enough gravity were at the surface, that not only could material objects not leave the surface, but light itself may bend and be trapped Karl Schwarzchild (1873-1916) In 1916 used Einstein’s General Relativity to define a Black Hole Defined the “event horizon” gravitational radius of a black hole AKA the … “Sch ....etc

Until recently, though, the price of an LED lighting system was too high for most residential use. With sales rising and prices steadily decreasing, it's been said that whoever makes the best white LED will open a goldmine.
White LED lighting has been used for years by the RV and boating crowd, running off direct current (DC) battery systems. It then got popular in off-the-grid houses, powered by photovoltaic cells. It used to be that white LED was possible only by rainbow groups of three LEDs -- red, green, and blue -- and controlling the c ....etc
