Lamps are devices designed to illuminate a space and create an artificial light source. They differ in shape, size, power, denomination and type of voltage used, as well as the method of obtaining lighting. The most popular is the traditional incandescent lamp. In addition to it, halogen, fluorescent, energy-saving, neon, xenon, quartz and other types of lamps are used.
Currently, the incandescent lamp can have different power, size and operating voltage. These devices are arranged as follows. A metal arc (usually made of tungsten) is located in a glass bulb, through which an electric current flows. During the passage of electricity, heating occurs, and the incandescent lamp begins to radiate a large amount of heat and light energy. The main disadvantage of this device is the allocation of a largeamount of heat.
When replacing appliances immediately after switching off or during operation, you can get burned if you do not use protective equipment. In addition, lamps cannot be used in fixtures that are limited in temperature. For example, a night sconce should not have a 100 watt incandescent lamp. However, the devices also have many advantages. Firstly, this is a large power spread (from 15 to 1000 watts). In addition, light bulbs can be powered by various voltage sources (AC or DC, from 1 to 240 volts). An incandescent lamp may have diffusing and transparent bulbs.
Halogen lamps are similar to their counterparts, only in their flasks there are bromine or iodine vapors. A small improvement allows you to increase the light output and double the service life of the device. Otherwise, it is a normal device.
The lumen incandescent lamp also contains a gas that, thanks to a special coating (phosphor), causes visible light emission when a current passes through it. The advantage of these devices is the increased supply voltage, reaching 380 volts. Also, these devices have a low heating temperature (up to 40 degrees), and their service life is much higher.
Daylight lamp is mainly used in industrial environments to illuminate industrial areas, creating light that is as close as possible to natural light.
Energy-saving lamp is a device thatwhich has reduced energy consumption. By its design, it is gas-discharge. This fixture uses up to eighty percent less electricity than a conventional incandescent light bulb, while 5 times longer life. In addition, energy-saving lamps do not heat up very much. The main disadvantage is their relatively slow heating and high cost. Despite this, they are gaining popularity with consumers.
Ultraviolet and quartz lamps are used in special areas of human activity. For example, in medicine, quartz performs a bactericidal function or is used to treat patients. Ultraviolet is used in forensics, trade, and also in solariums to get a tan.
