Bulb: varieties

Lamps are devices intended to illuminate the space and create an artificial light source. They differ in the shape, size, capacity, value and type of voltage as well as method of obtaining lighting. The most popular is the traditional incandescent light bulb. In addition to her use halogen, fluorescent, energy saving, neon, xenon, quartz, and other types of lamps.

Currently, the incandescent lamp may have different power, size, and operating voltage. These devices are constructed as follows. In a glass bulb, a metal arc (usually tungsten) through which an electric current flows. During the passage of the electricity is heated, and the bulb begins to emit a large amount of heat and light energy. The main disadvantage of this device is the large amount of heat.

During the replacement of the devices immediately after shutdown or in the process, you can burn yourself if you do not use protection. In addition, the lamp cannot be used in fixtures that are limited by the temperature level. For example, in the night bra should not be an incandescent lamp of 100 watts. However, the devices have many advantages. First is a large range of capacities (from 15 to 1000 watts). In addition, light bulbs can be powered by different voltages (AC or DC, from 1 to 240 volts). Incandescent may have a scattering and transparent envelope.

Halogen lamps are similar to their counterparts, only in their flasks fumes of bromine or iodine. A small improvement can increase the luminous efficiency and increase the service life of the device twice. The rest is the usual device.

Incandescent lumen also contains a gas which, thanks to a special coating (phosphor), causing visible light emission after the passage of the current through it. The advantage of these devices is the high power supply voltage reaching the level of 380 volts. Also these devices have a low temperature heat (40 degrees), and their lifetime is much higher.

Fluorescent Lamp is mainly applied in the production conditions for illumination of industrial premises, creating a light that is as close as possible to natural.

Energy Saving lamp is a device which has a reduced energy consumption. By design, it is discharge. This device uses up to eighty percent less energy than ordinary incandescent lamp, the service life is increased 5 times. In addition, energy saving lamps and little heat. The main drawback is their relatively slow intensity and high cost. Despite this, they are gaining popularity among consumers.

Ultraviolet and quartz lamps are used in special spheres of human activity. For example, in medicine, the quartz performs bactericidal function or used for the treatment of patients. The ultraviolet light used in forensics, trade, as well as in tanning beds for tanning.
