Lamps of Halogen And Their Benefits Over Standard Bulbs

Tuesday, June 16th, 2009

For any lighting situation, general or for specific accenting, Halogen lighting is the ideal solution.

It is distinguished by its brilliance and provides lively illumination of spaces, rich in contrast and promotes an active and creative workspace.

When shone onto a coloured surface, they look brighter and more appealing than they would under normal incandescent light.

With halogen lights you create your own custom lighting solutions for any occasion as they are available in different colours and sizes, and with or without a reflector.

The usual places you will see halogen lights are places like hotels or retail fashion stores, ideal for bright, pleasant atmosphere and a clean sparkling light.

Halogen lamps can provide extremes of widespread, soft, shadow-free illumination or sharply defined narrow beams thereby allowing creative accents.

Because halogen lights give off a cleaner, crisper light, and allow for savings on energy, soon they will undoubtedly replace traditional incandescent light bulbs.

The Science Behind Light Bulbs

Thursday, May 14th, 2009

The structure of a light bulb is fairly simple. At the base, there are two small metal contacts which are connected to the ends of the electric circuit. These metal contacts are attached to two hard wires. These wires are attached to a fine metal filament. This filament stands in the centre of the bulb, held in place by a glass mount. The filament and all the wires are encased in a glass bulb which is filled with an inert gas, like argon.

When a light bulb is connected to a power supply, the electrical current runs from one metal contact to the other, moving through the filament and all the wires. Electrical current in a solid conductor is measurable by the movement of free electrons (ones that detach themselves from atoms) from an area with a negative charge to an area with a positive charge.

As the electrons zip along through the filament, they are constantly bumping into the atoms that make up the filament. The energy of each impact vibrates an atom — in other words, the current heats the atoms up. A thinner conductor heats up more easily than a thicker conductor because it is more resistant to the movement of electrons.
