SYNOPSIS: ENERGY SAVING LAMP CONTROLLER helps in reducing energy consumption by reducing the applied voltage wthout a proportionate reduction in the illumination level. In large scale industries, the three phase voltage is maintained at 415 Volts as per requirement. this means that the voltage across phase and neutral will be 239 Volts. This is far above the rated voltage of the lamps. Lot of energy is wasted as the corresponding benefit in terms of illumination is not obtained. Life of the lamps also get reduced. The ESLC can be used to reduce the voltage applied to the lamps to anywhere between the supply voltage and 180 volts TO SAVE ENERGY AND EXTEND LIFE OF THE LAMPS.

These are suitable for flourescent and other types of lamps including incandescent, mercury vapour, metal halide and quartz. The device enables the user to adjust level of savings upto 50%. The first 10% saving can be realised without any perceptible drop in illumination level. The ESLC controls entire circuits of lighting from the lighting distribution board and is a superior alternative to switching off lamps, on a selective basis to save energy. Further delamping results in uneven distribution of lighting. With the ESLC it is possible to reduce the energy consumption wthout substantially reducing the level of illumination and obtain even distribution. It is easy to install.

OPTIONAL
Facility to control the output of the ESLC based on the ambient light i.e., when the ambient light is high, the output of the ESLC is automatically reduced to obtain the best energy saving possible wthout any reduction in the level of illumination.

PERFORMANCE TEST REPORTS

Performance Test at an Engineering Unit :

LOAD : 12 Nos. of 40 Watts fluorescent lamps with Electronic Chokes.

I.         Without Energy Saving Lamp Controller :

Voltage	:	219 V
Current	:	3.1 A
Power	:	219 * 3.1 *1 (P.F is considered as unity, because, load is with Electronic choke)
	:	678.9 W

II. a.   With Energy Saving Lamp Controller(auto mode) :

Voltage	:	209 V
Current	:	2.9 A
Power	:	209 * 2.9 *1
	:	606.1 W

Energy Saving 678.9 - 606.1 W = 72.8 W

In percentage : 72.8/678.9 * 100 = 10.7%

II. b.   With Energy Saving Lamp Controller(manual mode) :

Voltage	:	180 V
Current	:	2.9 A
Power	:	180 * 2.9
	:	522 W

Energy Saving 678.9 - 522.0 W = 156.9 W

In percentage : 156.9/678.9 * 100 = 23.1%

Conclusions :

a)       Energy saving in auto mode (automatic adjustment of voltage based an ambient                 light) 10.7%

b)       Energy saving when output voltage is manually set at 180 : 23.1%

Performance Test at a Textile Unit given by the Customer :

We wish to inform you that we have tested your Energy Saver Light Controller (make Vijay Energy Products, Madras) with 20 Nos. 80 Watts Tube Light Fitting for a week and the test results are as follows :

Average Energy consumed/hr. Without the Energy Saver	2.02 units
Average Energy consumed/hr. With the Energy Saver	1.74 units
Saving	0.28 unit

Assuming the cost of energy is Rs.3/- per unit, there is a saving of Rs.20/- per day or Rs.7258/- per year.
