How LED Light Bulbs Are Made

Hundred-and-thirty years ago, Thomas Edison created the first successful test of the durable incandescent lamp. Some minor improvements along the way, basic Edison lights up in the technology world since then. This is about to change. We are on the cusp of the solid-state lighting revolution, which will ultimately replace Edison's light bulbs more energy-efficient lighting solution. Solid state LED will eventually replace nearly all of the hundreds of billions of incandescent and fluorescent lamps are used throughout the world. In fact, as a step in this direction, Obama introduced a new chairman last June, more stringent standards for lighting, which supports the phasing out of incandescent bulbs (which has been prohibited in parts of Europe).

To understand how a revolutionary new LED light bulbs and why they are still expensive, is instructive to examine how it is produced and compared to the manufacture of incandescent light bulbs. This article describes how the bulbs will be made contrary to this process, a description of a typical manufacturing process for LED bulbs.

So, let's start by taking a look at how the production of conventional light bulbs. You will see that this is a classic example of the automated industrial process refined for more than a century of experience.

While the individual incandescent bulb differ in size and power, each of the three basic parts: the filament of the bulb, and the base। The filament made of tungsten. Although very fragile, heat-resistant tungsten fibers is above 4500 ° Fahrenheit. The connecting wires are generally introductory or nickel-iron wire. The wire is dipped in a borax solution to the wire is stuck to the glass better. The bulb itself is made of glass, and contains a mixture of gases, usually argon and nitrogen, which increase the life of the filament. Air is pumped out of the lamp, and location of the gas. The standardized base holds the entire assembly into place. The fund called the "Edison screw base." Aluminum is used for external and internal glass used to insulate the fund.
