Currently, increasing requirements for sources of e-mail. lighting, especially in terms of saving electricity. energy. Such devices include the LSP lamp (dust and water tight luminescent lamp). At the same level of illumination, it consumes two times less electricity than ordinary incandescent lamps. The luminescent light sources installed in it have a much longer life than Ilyich’s bulbs.
Purpose and device
The LSP lamp can be installed both on walls and on the ceiling. It is usually used for lighting industrial premises, in the air of which there is an increased content of dust and moisture. Increased moisture resistance is achieved by tightly pressing the lampshade to the base of the lamp using special clamps, as well as a sealant laid along the entire perimeter of the base. The lamp housing is made of metal. For those rooms where tightness is not so important, LSPs without a sealant with fewer clamps are used, with a degree of protection IP-43. Their cost is less than that of hermetic ones. The plafond is made of opaque shock-resistant polymer glass. For ease of use, it is attached to the metal base with a cord that allows you to hold it in a disconnected position. It is not recommended to use the LSP lamp in residential premises, but if you still decide on this, then it is necessary to provide mixed lighting, that is, do not exclude the combined use with incandescent lamps or others (for example, halogen or LED). This is necessary to reduce the harmful effects of fluorescent lighting on human vision.
Control gear
The LSP lamp is equipped with ballast control equipment (PRA) (in common parlance - a throttle), designed to ignite and maintain the combustion of a fluorescent lamp. The package also includes:
- starter involved in the ignition process;
- a capacitor designed to compensate for reactive power (the system, of course, can work without it, but the efficiency will decrease dramatically).
Advantages of electronic ballasts
The above-described structural elements of the lamp have several disadvantages. For example, during operation, the throttle may hum, the lamps flicker for a long time before ignition, and the starter creates radio interference. Therefore, now luminaires with electronic ballasts installed in them are becoming more widespread. Consider their advantages:
- saving email energy up to 30%;
- the lamp life is increased up to 50% compared to those fixtures that use electromagnetic ballasts;
- there is no ripple in the light flux ;
- lamps turn on without delay;
- completely silent work;
- the mass of the device is less.
The cost of such a lamp is, of course, higher, but over time, these costs pay off and give significant savings. Lighting devices are available with one, two or four lamps of various capacities. For example, the LSP 2x36 EPRA lamp is a two-lamp lamp with electronic ballasts. The power of one lamp is 36 watts. And LSP 2x40 lamps have two 40 W lamps.
All these devices are powered by AC with a rated voltage of 220 V.
