The advantage of Energy saving lamps (Energy saving light)
The operated theory of electronic Energy saving lamps: Conversely change 50HZ to 20-50KHZ high rate voltage by mading use of the ecetronic ballast to light up the fluorescence light.

Energy saving lamps are several advantages as follows:

1. High shine efficiency.
Shine efficiency means the rate of the luminous flux gave off from one lamp-house and that wasting electric power,
which could be figured with lumen per tile or LM/W ( The luminous flux means the rate of flow of light per unit of time, which is the important guide for scaleing of the light, showed by LM.) Just compare with the fluorescence lights and ordinarily lights closely, the fluorescence lights are 5 or 6 times lighter than the ordinarily lights, such as the luminous flux of 11W energy saving lamps is equal to the 60W ordinarily incandescence lights.
2. long natureal life.
The natureal life means the total time of the finished light from lighting up to burn or the total time from working till it under the standard of natureal life. the rating natureal life of a ordinarily incandescence lights bulb is 1000 houres, while the compact luorescence lights is 5000 houres.
3.The good color rendering.
Different lamp-house shows fidderent color. We mensurate it with CRI (Color rendering index), its range is from 0 to 100.
The CRI of incandescence light and day sunshine is 100. The height of CRI directly feedback the quality of color rendering of light.
The higher CRI of light could more clearly show the true color of the object under its irradiation.
otherwise, the object would distortion. Normally, if the CRI of light is over than 75, the object
could show the true color truly and won't distortion.
The compact fluorescence light is made by rare soil tricolor fluorescence k powder, which CRI is about 80RA,
which is obviously highter than the CRI of general fluorescent lamp. If made by low-cost halogen powder as the material, it won't have this kind of effect.
4. Small volume, beauty scykotm, and convenient use.
Since compact fluorescence light has upper power factor, so Energy saving lamps volume small and beauty,
Energy saving lamps also could be used as the beautiful ornament. The lamp holder of integrative energy saving lights has same specification as general bulb, so it could instead of general bulb directly. The market for Energy saving lamps is large, so they are easily popularized and used.
Energy saving lamps could be said that the compact fluorescence light centralizes the saving of power and long life of daylight lamp, the small volume and good color rendering, and convenient use of incandescence light and this kind of advantages. It feels no regret to be the model lamp-house during the modern indoor lights.
