Every year on television and other media louder and more clearly states that the mineral reserves at the end, so the cost of energy is increasing, and it is time to think about saving.This also applies to electric power as its reception is interconnected with other areas (oil for the lubrication of bearings of generators, metal smelting plants for the wire and so on.).To reduce the cost of paying the bills at first advised not to forget to turn off the light in the rooms where it is not necessary, then replace the light sources in the more advanced, and in the end - to apply the technology of "smart house".Turn off the lights have all learned to computerization of the home of an average citizen is still far away, but to learn what the luminous flux and change the bulb - it is the time, especially fluorescent and LED solutions are already available in every market stall, not to mention the shops.
Few people know that choosing a replacement usual incandescent lamps, it is necessary to pay attention not only to the consumption of new models of electric power and color temperature, but also on the emitted light beam.To forget this is not recommended, as the situation may arise when the vaunted model of the new lamp on the old parameter yields.Its light output may be less than the serve faithfully.Such a change would allow and even save energy, but is unlikely to bring joy.What is the light output with respect to light lamps?This is the amount of radiant energy component of the entire spectrum of radiation that is detected by the human eye, and is defined as "light."For measurement, a special spherical recorder.
luminous flux of the filament lamp, for many years is the standard light source, long-measured and determined to visit.Released in 1999 for the popular 60-watt bulbs, it indicates the minimum value of the luminous flux not less than 620 lm (lumens) and varieties with increased flow must produce more than 710 lumens.And, after a month of continuous operation of the luminous flux reduction should not fall below 85% of nominal.On this parameter incandescent none.A lot or a little - 600 lumens?
To answer this question it is necessary to get acquainted with the technical specifications of their modern counterparts, based on light-emitting diodes.Luminous Flux LED lamps indicate the packages, not all manufacturers.The reason is clear: it is always written in large letters, the power consumption (it is really small) and color temperature and, moreover, the light output either not mentioned or written in small letters.
For example, consider the incandescent lamp 100 watts and equates it LED model.Everyone knows that LEDs have a relatively low capacity, but allows to effectively deliver the light energy in terms of watts each.If an incandescent lamp (100 W), this parameter is 10 lm / W, then the entire LED 61 lm / W.Someone has already found that the luminous flux of the LED lamp power of 11 W 617 lm, while the 100 W incandescent - 1000 lm.Bottom line: at present for the replacement of Example incandescent need to purchase a 15 W LED model.
Every day there are new varieties of bulbs that can more efficiently deliver light energy.Using advanced control circuits and diodes can increase the final efficiency.The main thing when buying - read specifications given by the manufacturer.And not only what is written in large letters on the front side, but the rest of the specified parameters.
