In everyday life, incandescent lamps and gas-discharge lamps are most convenient for use. They are suitable for many types of luminaires and are easy to use. For industrial and street lighting, certain types of discharge lamps are used - sodium high and low pressure.
Incandescent lamps have a short lifespan and low efficiency, but due to their affordable price and wide distribution, they are still used for home lighting. But recently, traditional incandescent ones have been replaced by gas-discharge ones. Lamps of this type have been used in industrial lighting - in offices, schools, shop windows, hospitals. They are distinguished by their long service life and economy.
Gas-discharge energy-saving lamps contain mercury vapor in the bulb. Due to an electric discharge in metal ions, ultraviolet light is emitted, which is converted into visible light by a phosphor - a special substance. The flask has a curved shape in the form of a tube or spiral folded several times. Such lamps are most in demand for home lighting: their small dimensions allow them to be installed in almost any lighting device and save on electricity.
The discharge can also use inert gases (neon, xenon, and others) or sodium vapor. They significantly save energy, have high efficiency and are used in industrial lighting. The most advantageous lamps of this type are sodium lamps.
Sodium low pressure gas-discharge lamps emit monochrome yellow light and have a low transmission of the light spectrum. Therefore, they are used in street lighting: the efficiency of such lamps is high, and the color of the luminous flux in this case does not matter.
High pressure sodium bulbs have found their way into greenhouse production: bright orange light has no side effects of ultraviolet radiation and promotes plant growth all year round. They have the highest efficiency among discharge light bulbs.
The OSRAM incandescent light bulb, despite the abundance of modern types, remains in demand. It does not require additional starting devices, it works stably in different environmental conditions and has a low inertia when turned on. Incandescent lamps and other types - gas-discharge, energy-saving, LED - can be ordered with delivery from a reliable manufacturer: https://lightcom24.com .
