Luminescent lamps are very popular today due to uniform and bright lighting which is given. Their practicality and reliability perfectly is suitable for inhabited, office, sports, industrial and trade rooms. However, as well as any other luminous sources, luminescent lamps have the advantages and shortcomings.
All about luminescent lamps
Luminescent lamps are flasks with gaseous luminous source. The visible luminescence is allocated by phosphor and ultra-violet radiation which are combined and evenly fill space with the soft muffled luminescence.
Dome fluorescent lamps happen:
- raster; - consignment notes. Laid on lamps whereas raster designs are ideal for false ceilings best of all are suitable for the room without false ceiling. Also there are models of luminescent lamps intended for rack ceilings.
Laid on lamps, unlike raster, possess the simple, but precisely thought over design. Thanks to it, they light the much bigger area, spending at the same time less energy, than raster lamps.
Most often laid on luminescent lamps use in rooms with very high ceilings.
It is possible to establish laid on designs on ceilings with any surface. At burn-out of lamp it is easy to replace it with new bulb which will allow to save significantly on the maintenance of the luminescent lamp at the expense of the long term of the service.
Pluses of luminescent lamps
In comparison with traditional lamps, the surface luminescent mounted luminaire has bigger luminous efficiency, wide choice of shades, notable power saving and long term of operation. Today simple electromagnetic lamps were succeeded by modern models with electronic puskoreguliruyushchy devices. They are absolutely silent, do not flicker and evenly distribute light. Electronic ballasts allow new lamps to consume 30% less electric power, increase life cycle by one and a half times, not to be afraid of sharp temperature differences and smoothly work in extreme conditions.
Lamps with pylevlagootalkivayushchy cover which as much as possible protects them from moisture, dust and other foreign substances are in quite great demand.
In addition, modern luminescent lamps have the increased capacity and efficiency, are protected from short circuit, are more reliable, do not demand frequent technical maintenance and suppress radio waves. The average resource of such lamps is calculated for ten years of trouble-free operation.
Minuses of luminescent lamps
Among shortcomings of luminescent lamps are: restriction of single power up to 150 W, complexity of schemes of connection, lack of light at low tension in networks, the increased noise during the work and acoustic hindrances, the high price, harmful pulsations of luminous flux and big sensitivity to voltage surges.
As such lamps contain substances, unhealthy (mercury and phosphorus), on the expiration of operation they need to be utilized properly.
At temperature reduction the luminescent lamps can not be lit or die away. Also in their radiation there is no part of color range that can result in fatigue of eyes and distortion of color perception. Besides, fluorescent lamps by the end of term of the service reduce luminous flux, several minutes are warmed at inclusion, are sensitive to cold, react to increase in humidity and often flicker at resource exhaustion from intensive use. One more serious minus of luminescent surface mounted luminaires is harm from ultra-violet radiation. In premises it is not recommended to use lamps which power exceeds 20 W.
Luminescent lighting
Luminescent surface mounted luminaires can be with the mirror reflector, white raster and also with the opal or prismatic diffuser of light. Most such lighting is demanded at offices, hotels, shopping centers, gyms, however luminescent lamps will perfectly fit also into apartment interior.
The lamp with addition of special substances which give the chance to change color of luminescence will become stylish option of room luminescent lighting.
At the correct placement of surface luminescent mounted luminaires even the room with big area will be ideally lit. This kind of lighting equipment creates pleasant soft illumination, giving large amount of light and consuming at the same time the minimum quantity of the electric power during the work in the room or its repair. Also today it is possible to get with delivery not only normal fluorescent lamps – on sale are ring, ultra-violet and bactericidal lamps. With their help it is possible to compensate lack of ultraviolet during the autumn and winter period, to disinfect the room and to receive the quiet equal luminescence which is not irritating eyes.
